Multi-roller ginning device used for cotton spinning

Abstract

The invention relates to the technical field of compression roller ginning equipment, in particular to a multi-roller ginning device used for cotton spinning. The multi-roller ginning device comprises an unginned cotton feeding port (1), cotton feeding rollers (2), a cotton storage box (3), a cotton cleaning roller (4), a cotton rolling box (6), a front box (7), a middle box (8), a cotton extracting licker-in (11) and a hairbrush roller (16); unginned cotton which is smooth in surface is difficult to be hooked by sawteeth on a saw blade roller (10), falls out of the device from a gap between the cotton extracting licker-in (11) and a resistance shell rib (9) in the front box (7) and does not enter the middle box (8), so that content of impurities like cotton seeds and dead cotton in ginned cotton is lowered. The multi-roller ginning device has the advantages that the sawteeth on the saw blade roller are inclined, so that separating rate of fibers and the cotton seeds is increased; the content of the impurities in the ginned cotton is low, and ginning efficiency is high.

Description

technical field [0001] The invention relates to the technical field of pressure roller cotton ginning equipment, in particular to a multi-roller cotton ginning device for cotton weaving. Background technique [0002] Cotton is an important economic crop in my country, with 5.3333 million hectares planted all year round, and it is the main source of income for cotton farmers in my country. However, there are still many deficiencies in cotton ginning. In ancient times, cotton ginning relied on manual work and pressing rollers. The original manual cotton ginning is to spread the seed cotton on the supporting plate and rub it with a pressing roller, so that the fibers are pressed between the pressing roller and the supporting plate and left in front of the mouth line of the two with the help of friction, and the cottonseed is blocked. The back of the mouth line where the pressure roller and the supporting plate are in contact, and moves backward with the rolling motion of the p...

The original manual cotton ginning is to spread the seed cotton on the supporting plate and rub it with a pressing roller, so that the fibers are pressed between the pressing roller and the supporting plate and left in front of the mouth line of the two with the help of friction, and the cottonseed is blocked. The back of the mouth line where the pressing roller and the supporting plate are in contact, and moves backward with the rolling motion of the pressing roller; its ginning efficiency is low, and the separation rate of fibers and cotton seeds is poor

The subsequent cotton gin uses a pair of pressure rollers to replace the manual support and pressure rollers. The upper roller rotates at a slower speed and the lower roller rotates faster. When the two rollers rotate in the opposite direction, the cotton fiber is pulled by the friction of the pressure rollers. When separated from the cottonseed, the rotation of the pressing roller can be operated by hand or by foot. The fiber made by the pressing roller gin has a high impurity rate, poor fiber uniformity, less residual fiber on the cottonseed, and yellow root content in the lint. More, the yellow root content in the lint is more, which is not good for the quality of the yarn, because the yellow root is not easy to remove during the spinning process
