Seed cotton opening device of seed cotton foreign fiber stripping machine

Abstract

The invention relates to a seed cotton opening device of a seed cotton foreign fiber stripping machine. The device is provided with a casing, wherein the upper and lower ends of the casing are opened; a feeding roller and an opening roller are arranged in the casing; the feeding roller is correspondingly and obliquely arranged above the opening roller; feeding sticks are uniformly distributed on the feeding roller; opening sticks are uniformly distributed on the opening roller; the feeding sticks and the opening sticks are staggered with one another; the rotating directions of the feeding roller and the opening roller are opposite; the rotating speed of the feeding roller is between 15 and 45 r / min; the rotating speed of the opening roller is between 200 and 300 r / min; and the feeding roller and the opening roller are arranged in grooves on inner walls on both sides of the casing respectively. The device has a simple structure and a reasonable design. Seed cotton entering from the upper end opening of the casing and air current are prevented from directly flowing into a gap between the feeding roller and the opening roller and good opening effect is achieved. The seed cotton is rapidly dispersed between the feeding roller and the opening roller and opening efficiency is high.

Description

technical field [0001] The invention relates to a seed cotton foreign fiber removal machine, in particular to a seed cotton opening device of the seed cotton foreign fiber removal machine. Background technique [0002] In the textile industry, the impurities mixed in the seed cotton will lead to increased fabric defects, uneven dyeing, affecting the quality of the fabric and causing losses. The seed cotton foreign fiber removal machine is used to remove foreign fibers such as mulch film, hair, chicken feather flakes, and woven bag silk mixed into the seed cotton during planting, picking, and transportation from the seed cotton. At present, foreign fiber removal machines for seed cotton mostly use licker-in winding method, internal suction method, external suction method and other methods to remove foreign fiber impurities; however, these cleaning methods all have serious deficiencies. The licker-in winding method requires frequent replacement of licker-in rollers for cleani...

AI Technical Summary

Problems solved by technology

At present, foreign fiber removal machines for seed cotton mostly use licker-in winding method, internal suction method, external suction method and other methods to remove foreign fiber impurities; however, these cleaning methods have serious deficiencies

The licker-in winding method requires frequent replacement of licker-in rollers for cleaning, which is labor-intensive; many transmissions, high noise, and high power consumption; the effect of removing foreign fibers is not good

Internal suction method and external suction method are not ideal for removing long and heavy foreign fibers

The better foreign fiber removal method is CCD detection method. If the seed cotton to be cleaned of impurities enters the foreign fiber removal machine, if it gathers too much, it will affect the effect of subsequent detection and removal.
