What is a paper cutter?

Paper cutter is the equipment for cutting flat paper in paper industry. It is divided into flying knife paper cutter (divided into single knife and double knife) and flat knife paper cutter. Swing cutter includes a longitudinal cutting mechanism consisting of an upper knife and a lower knife and a transverse cutting mechanism consisting of a rotating long knife and a fixed bottom knife. It can cut 6~ 10 paper roll at the same time. The flat knife paper cutter is a platform with a lifting knife, which cuts flat paper into specified sizes. Used to cut large pieces of paper into small pieces.

Classification of paper cutting machinery

Paper cutters are composed of household paper cutters and industrial paper cutters, with various types and different degrees of automation.

Household paper cutter

Household paper cutters are composed of paper cutters such as toilet paper cutter, napkin cutter, paper cutter, square cutter, drum cutter, toilet paper cutter and facial tissue cutter. According to the different paper products, the corresponding paper cutting machinery is also different.

Toilet paper cutter

Toilet paper cutter refers to band saw, that is, band saw cutter used to cut toilet paper roll. Band saw cutting machine is equipped with automatic sharpening and moving platen device, which can cut the required roll paper into finished products according to the required length and width.

Suggestion: If you need to find paper cutter products, try to find paper-making machinery and equipment manufacturers, such as Gorgeous Machinery: Gorgeous Machinery is located in Weifang City, Shandong Province, mainly engaged in paper cutters such as toilet paper cutter, web cutter, band saw cutter, napkin cutter, square cutter and facial tissue cutter.

Industrial paper cutter

Industrial paper cutters include manual paper cutters, electric paper cutters and numerical control paper cutters, which are mainly used for cutting industrial paper or other products. Suggestion: If you need to find an industrial paper cutter, you should know the purpose of the product as much as possible and find the corresponding equipment manufacturer.

develop

Paper cutter is a traditional product, which is used to meet the paper cutting demand in the later stage of printing. From mechanical paper cutter to magnetic tape

Paper cutter control Paper cutter has developed into a cutting system with microcomputer program control, color display, full image operation guidance and visual processing, computer-aided cutting external programming and editing production data, which makes production preparation time shorter, cutting accuracy higher, labor intensity lower and operation safer.

A paper cutter with high cutting performance is suitable for cutting labels, carbon paper and hardcover books. Semeigao specializes in manufacturing high-precision, high-speed hob web paper cutter.

Small paper cutter

Small paper cutters are divided into thick paper cutters and small office paper cutters.

Thick paper cutter

Thick paper cutter, some people call it manual cutter from the driving mode, desktop cutter from the placement position and so on. This paper cutter is mainly suitable for cutting paper neatly before binding a small number of documents. This paper cutter is widely used in office or finance, as well as photo studios and digital print shops.

Characteristics of thick paper cutter:

1) The maximum cutting width is generally around 430 mm.

2) Small, easy to use, does not take up too much space.

3) The cutting precision of the incision is not high.

4) Cheap and economical.

Small office paper cutter

The structure of small office paper cutter is complex, which is mainly composed of main machine, workbench, paper pressing mechanism, paper pushing mechanism and cutting mechanism. This paper cutter is mainly suitable for cutting paper neatly before binding a large number of documents. The paper cutter is widely used in modern digital express printing, middle and high-grade office, library, national public service institutions and small and medium-sized printing.

From paper pushing mechanism to cutting mechanism, it can be divided into manual paper cutter (purely mechanical structure) and electric paper cutter.

From the driving mode of paper pressing mechanism, it can be divided into mechanical paper pressing and hydraulic paper pressing.

Judging from the size display mode and the positioning of the paper pusher, it can be divided into digital display paper cutter and program-controlled paper cutter (the paper cutter with pure mechanical structure is generally embedded with a steel ruler on the table, and the control of the paper pusher is the same as that of the digital display paper cutter). The main difference between digital display paper cutter and program-controlled paper cutter lies in the control of paper pushing mechanism. Program-controlled paper cutter not only greatly improves the efficiency, but also effectively reduces the labor intensity of operators.

High-end small office paper cutter is not only reflected in the stability of cutting accuracy and performance, but also has multiple protection in safety, which is embodied in dual-hand differential protection and photoelectric protection.

Characteristics of small office paper cutter;

1) The cutting width is generally between 430mm-800mm.

2) Small, easy to use, does not take up too much space.

3) A large number of cutting objects can be cut.

4) The cutting precision of the cut object is high.

5) According to the size and configuration of cutting width, the price ranges from several thousand yuan to several hundred thousand yuan.

Problems needing attention in the use of paper cutter

material

In the actual use process, the paper cutter has to face a variety of cutting objects, except paper and cardboard, as well as leather, plastic, cork floor and PS version. Because there are many kinds of materials to be cut, different paper pressure should be adopted according to different materials, and the angle of cutting edge should be changed to ensure high-quality cut products.

Cutting edge opening angle

The choice of cutting edge angle is a very important part of cutting work. In other words, a good paper cutter should be equipped with a good paper cutter blade and sharpening technology. However, in the after-sales service of paper cutter, we found that many paper cutter users often ignored this point. The way, method and angle of sharpening the paper cutter blade are wrong, which increases the impact force during cutting, causes the safety screw to loosen or even break, and finally causes mechanical damage.

The range of materials that need to be cut by paper cutter is wider and wider, such as beer aluminum foil label, carbonless copy paper, honeycomb cardboard, magnetic card, photosensitive film and so on. These materials will encounter different practical problems in the cutting process. For example, when carbon-free copy paper is cut, it is prone to indentation, while when magnetic cards and photosensitive films are cut, the paper presser cannot be fixed, resulting in cutting out waste products. These problems can be solved smoothly by adjusting the pressure of printing machine and improving the blade and cutting transmission system. However, as far as I know, only some domestic paper cutter manufacturers can solve all these problems.

Flat paper cutter

abstract

Flat paper cutter is a widely used cutting machine, which can be used to cut paper, leather, plastic, cardboard and other materials. Paper cutter is mainly composed of main machine (also known as gantry), workbench, paper pushing mechanism, paper pressing mechanism and cutting mechanism. The paper pushing mechanism is used for paper pushing positioning and post-adjustment; The paper pressing mechanism presses the positioned paper to ensure that the original positioning accuracy is not destroyed during cutting; The cutting mechanism is used for cutting the paper; The side baffle is used as a side stop gauge; The workbench plays an auxiliary role.

Printing, packaging, book binding and other production from cutting to finished product printing, wool binding need to be cut with a paper cutter, so the paper cutter is an important equipment for post-press processing. Flat paper cutter is widely used in printing plants, binding plants, packaging plants, paper products processing plants and so on.

Cutting technology of flat paper cutter

1) Adjust the position of the paper pusher according to the size of the cut paper.

2) Place the punched paper near the front surface of the paper pusher and the side baffle to position the paper.

3) The paper presser first descends to press the paper, and then the cutter descends to cut the paper.

4) After cutting, the cutter leaves the paper stack and returns, and then the paper presser rises and resets.

Factors affecting the safe use of paper cutter

The safety of paper cutter is a problem that many digital printing practitioners easily ignore, which affects the safe use of paper cutter from the following aspects:

1. Brake device. In order to save money, many manufacturers use the circuit braking principle, that is, the upper and lower limit sensors cut off the power supply of the cutter motor to brake. This equipment may lead to extremely dangerous situations such as "knife sliding" in the case of sudden power failure, loose socket and sensor failure. In order to put an end to this situation, the motor assembly with mechanical braking device must be adopted, so that no matter what circuit fault occurs, the motor is locked to avoid accidents.

2. The principle of double button operation. This requires pressing two buttons at the same time, otherwise the cutter motor will not act, which can ensure the absolute safety of single-person operation.

3. In the actual use process, it is often necessary for two people to cooperate with the operation, so the situation becomes very dangerous, which requires the paper cutter to be equipped with front and rear safety covers. When the safety cover is opened, the motor will not act to ensure safety.

4. The above are the safety factors that affect the use process. Therefore, when repairing and replacing the blade, the blade holder should be used to ensure that the blade is closed, which not only ensures the safety of people, but also ensures that the blade is not damaged.

5. Furthermore, the removed blade must not be put aside at will to avoid hurting people.

Therefore, first of all, we should buy equipment with high safety factor, and secondly, we should develop good habits, so as to ensure the safety at work.

Classification of flat paper cutter

1. From the driving mode of the paper pushing mechanism, the flat paper cutter can be divided into electric paper cutter (the positioning of the paper pushing mechanism can only be realized by manually pressing the button or controlling the motor or mechanical transmission mechanism to operate the corresponding mechanism), program-controlled paper cutter (the automatic positioning of the paper pushing mechanism can be realized by program-controlled system, and the positioning mode of the electric paper cutter can also be realized) and intelligent digital paper cutter between the two modes (the control system can realize automatic rough positioning and then perform manual fine adjustment).

2. Programmable paper cutter can be divided into three ways: stepping motor control, variable frequency speed control and AC servo control.

Both stepping motor control and frequency conversion speed regulation can achieve positioning accuracy of 0. 1mm and speed of 8- 14 m/min (the specific accuracy and speed will vary greatly depending on the control system and electrical components selected by the manufacturer), but the stepping motor control mode is noisy when starting, which is not favored by many paper cutter manufacturers and users.

Compared with variable frequency speed control, AC servo control mode has made a great breakthrough in the positioning accuracy and speed of paper cutter pushing board. The positioning accuracy can reach 0.025-0.0 15 mm, and the paper pushing speed can reach 16-20 m/min (the specific accuracy and speed will vary greatly depending on the control system adopted by the manufacturer and the electrical components selected).

3. From the operation interface (operation mode) of program-controlled paper cutter, it can be divided into three modes: button, touch screen, button and touch screen.

The program-controlled paper cutter operated by key mode appeared for the first time, and its efficiency was doubled compared with that of digital paper cutter, which improved the work efficiency for many users and created more wealth, and was favored by customers. However, after the new technology comes out, this mode can not be compared with the touch screen operation mode in terms of intuition and simplicity.

The touch screen operation mode can easily realize the functions of equal division, equal distance, cycle size, calculator use, calculation result input program and so on. , and the operation is simple and intuitive (the key operation mode requires the combination of several keys to realize some functions, and many customers consult the manufacturer for use after the operator is replaced, but the manual cannot be found); On the screen, there is an intuitive display of the state of the detection switch in each running link of the machine, which provides great convenience for troubleshooting common faults and saves time and money for the users and manufacturers of paper cutters.

The dual mode of buttons and touch screen can be used in combination, which can meet the old habits of some operators. At the same time, it provides additional input methods, which has a relative improvement in durability. However, in the case of touch screen operation mode, the interface and operation menu designed by the paper cutter manufacturer are reasonable, and the quality of the selected screen is stable and reliable, its significance is not great.

4. From the driving mode of paper pressing mechanism, it can be divided into mechanical paper pressing and hydraulic paper pressing.

Hydraulic paper pressing method can more accurately ensure the tolerance accuracy of equal length after cutting (commonly known as the accuracy of upper and lower knives), especially when cutting the incision with high density, the difference is particularly obvious. Therefore, with the emergence of hydraulic paper cutter, customers who require higher cutting accuracy no longer choose mechanical paper cutter.

The clutches of the paper pressing mechanism and the cutting mechanism are all driven by hydraulic pressure, which is also called full hydraulic or double hydraulic paper cutter. Full-hydraulic or double-hydraulic paper cutter has greater cutting force and obvious advantages when cutting high-density cutting objects, and the clutch is not easy to slip, so it is not necessary to adjust the gap of the clutch frequently.

5. According to the size display mode and the moving positioning of the paper pusher, it can be divided into digital paper cutter and program-controlled paper cutter (the paper cutter with pure mechanical structure is generally embedded with a steel ruler on the table, and the control of the paper pusher is the same as that of the digital paper cutter).

The main difference between digital display paper cutter and program-controlled paper cutter lies in the control of paper pushing mechanism. Program-controlled paper cutter not only greatly improves the efficiency, but also effectively reduces the labor intensity of operators.

6. From the width (maximum cutting width) of the flat paper cutter, it can be divided into split paper cutter (also called half-open paper cutter) and full-open paper cutter (full-sheet paper cutter). It has been mentioned in many articles, so I won't go into details here.

High-end flat paper cutter is not only reflected in cutting accuracy, performance stability, selection of materials, components and control system, but also has multiple protections in safety, which are embodied in dual-hand differential protection, photoelectric protection, electronic knife lock and so on.

Technical performance level of paper cutter products

Mainly manifested in the cutting accuracy, accuracy retention, quality stability, operation convenience and safety of the paper cutter.

There is a certain gap between domestic paper cutter technology and international advanced countries, mainly as follows:

① The control system is relatively backward and lacks automatic detection devices. As for the control system, China has just started to use PLC, while foreign countries adopt full-line computer control, which is used to monitor and adjust the executive components and preset parameters, thus automatically adjusting under computer control, greatly shortening the auxiliary time and ensuring the reliability of work.

② The complete set is poor, and domestic paper cutters are rarely equipped with peripheral equipment, that is, cutting production lines.

③ There is a certain gap between appearance and ease of use. However, through the efforts of domestic paper cutter manufacturers in recent years, the gap between domestic paper cutters and foreign products is rapidly narrowing, and some technologies are even at the leading level. At present, the control mode of foreign paper cutters is basically color microcomputer program control, while domestic paper cutters are mainly digital display, and a large number of mechanical paper cutters lacking safety protection exist and are sold. Microcomputer-controlled paper cutter is the development trend of paper cutter, and it is replacing other paper cutters with faster speed and larger area.

After pressing the "cut" button, the cutting machine runs up and down for more than two times, and the cutting machine is weighed. The main reasons for the connection of the cutter are that the limit switch of the cutter of the paper cutter fails or does not touch the limit switch, and the relay contact is stuck or slow.

Selection points of paper cutter

What can't be ignored is the price of paper cutter, which is an important factor in choosing Shenweida paper cutter. Compared with imported paper cutters, Shenweida has obvious price advantage and excellent performance. Preferential price is the main reason for customers to choose Shenweida paper cutter, and the after-sales service in China is also in place. At present, Shenweida paper cutter has the highest market share in China because of its high cost performance and practical benefits.
