What are the three major tasks of spinning frame and what is the technological process of spinning frame?

The technological process of spinning frame: roving tube-yarn guide rod-drafting device-front roller-yarn guide hook-steel ring spinning frame tube. If we must compare, I think strength is the most important, because the purpose of yarn is mainly used for textile.

The three main tasks of spinning frame are: drafting: drafting roving into sliver with required fineness and twist; Twisting the sliver into spun yarn with a certain twist; The spun yarn is wound into packages for storage, transportation and further processing.

Mechanism and technological process of spinning frame

Ring spinning frame is the most common. The ordinary ring spinning frame is a double-sided multi-spindle structure, which is mainly composed of feeding mechanism, drafting mechanism, twisting and winding mechanism and forming mechanism. Roving is unwound from the roving tube on the suspension spindle of the roving frame, passes through the yarn guide rod and the yarn guide horn moving slowly back and forth, and is manually fed into the drafting device for drafting.

The drawn sliver is output from the front roller, passes through the yarn guide hook, passes through the traveler and is wound on the bobbin tightly sleeved on the spindle. The spindle rotates at a high speed, and the traveler is driven by the yarn strip with certain tension to rotate on the rim at a high speed. Every time the traveler rotates, the drafted whisker will increase a twist. Because the rotation speed of the traveler is lower than that of the bobbin, the yarn continuously output by the front roller is wound on the bobbin.

The speed difference between the traveler and the bobbin is the number of turns wound by the bobbin in unit time. Relying on the control of the forming mechanism, the collar plate rises and falls according to certain rules, so that the spun yarn is wound into a certain shape of bobbin yarn.
