　　1. Automatic control of cotton feeding

　　The principle of automatic cotton feeding control is to timely feedback the ginning current to the microcomputer based on the density of the seed cotton roll. After a series of data processing, the voltage signal is sent to the frequency converter. Through frequency conversion speed regulation, the speed of the feeding motor is controlled to adjust the feeding amount. The density of the seed cotton roll is high, and the pressure on the sawtooth is also high. At the same time, the fiber content in the seed cotton roll increases, which increases the hooking force of the sawtooth on the seed cotton roll, accelerating the movement of the seed cotton roll and improving yield. But when the density of the cotton roll is too high, its movement resistance will greatly increase, which will actually hinder the operation of the cotton roll and be not conducive to improving yield.

　　2. The extension of the saw blade in the working box

　　The extension of the saw blade refers to the length of the saw blade extension measured perpendicular to the surface of the rib arc, 100mm below the working point of the rolled rib along the rib arc surface. During the embossing process of the embossing machine, the amount of saw blade extension directly affects the yield of the embossing. Generally speaking, increasing the extension of the saw blade increases the effective number of working teeth of the saw blade in the work box, enhances the ability of the saw blade to hook and pull fibers, and helps to increase production.

　　3. Prevent severe friction

　　During the processing of seed cotton, due to the friction between the movement of seed cotton and lint and the processing equipment, strands and knots are often formed. The parts that are prone to producing strands and knots are the working boxes of the sawtooth gin. Therefore, we should regularly inspect to ensure the smoothness of the saw blade (including serrations), ribs, and cotton roll box.
