As a carton factory, what should we pay attention to in the quality inspection of nailing boxes and pasting boxes?

1, box pasting: Pay attention to the amount of glue, the amount of glue is too small, the glue can't get into the paper, and the glue is not firm. When the amount of glue is large, it dries slowly. After stacking, it is easy to overflow the glue in the carton below due to the weight above, causing adhesion.

2. The "outside" of the carton at the joint should be in the middle of the pressing line at the joint, and it should not deviate too much from the inside to the outside, otherwise it will affect the size of the carton. Sticking boxes and nailing boxes are the same thing.

3. There can be no "scissors ruler" in the plastic box and nail box. The so-called scissors ruler means that the distance between the rubber mouth and the "outer" edge is different, with the upper width and the lower width, or the upper width and the lower width, just like two rulers in the shape of scissors. In this case, it is a common problem that the box is not square after loading, so pay attention to it.

Extended data:

According to the purpose of inspection, it can be divided into control inspection, receiving inspection and quality organization inspection and appraisal.

On the premise of ensuring the quality of carton products, carton enterprises can set up quality inspection institutions according to local conditions and be equipped with quality inspection personnel. Process inspection generally has the following forms: first article inspection, which is a preventive inspection in the manufacturing process of carton products, and is applicable to many types. The first article inspection shall be carried out by the operator himself and approved by the full-time inspector.

Patrol inspection means that inspectors check the product quality of related processes at regular intervals at the production site. Completion inspection refers to the inspection of a batch of processed products, mainly referring to the products between processes. Finished product inspection is the last inspection before corrugated box products reach users.

Product physical quality audit, the contents of physical quality audit of carton products are as follows:

The quality defects of cartons are divided into heavy defects and light defects, and detailed inspection items are written. After the actual audit, the quality defect items and audit results shall be recorded. Analyze the quality defects in time, fill in the carton quality audit report as detailed as possible, report the audit results to the competent leaders and relevant departments, and transmit and file them as quality information and data in time.

Quality control of production site: create a good production order and environment. Keeping the production site clean and hygienic is also an indispensable condition to ensure the quality of cartons. Such factors as working area, stacking and general transportation of appliances and products, workers' operating environment, and site cleanliness have important influences on the production and manufacture of corrugated boxes, which should be stipulated.

Therefore, the corrugated box production site can be effectively controlled point by point. The measures that can be taken include: formulating the management standard of corrugated box production site, regular inspection and assessment, site, machinery, equipment, raw materials, products in process, and station appliances. Take effective measures to reduce the damage caused by bumping, scratching, pollution and rough handling during carton handling.

Semi-finished products and semi-finished products should be listed and marked: in particular, there is no printing on the products coming down from the cardboard production line. If it is not listed, it is easy to cause confusion and mistakes in the case of similar varieties and specifications.
