A four-roller raw cotton opening and impurity removing device for textile use

Abstract

The invention provides a four-roller raw cotton opening and impurity removal device for the textiles and relates to the technical field of cotton thread spinning. The four-roller raw cotton opening and impurity removal device for the textiles comprises a frame, opening stirring rollers are fixedly connected into the frame, and a first filtering plate is fixedly installed on the portion, below theopening stirring roller, in the frame; a second filtering plate is fixedly connected to the portion, below the first filtering plate, in the frame, a draught fan is fixedly connected to the left sideof the frame, a dust collection box is arranged at the bottom of the second filtering plate, and a finished product collection box is arranged at the right side of the frame. According to the four-roller raw cotton opening and impurity removal device for the textiles, when raw cotton is stirred and pulled, the effect of hitting the raw cotton can also be achieved, the opening effect is improved, separation of impurities from dust is accelerated, in the rotation process, stirring rods can retract, the situation is avoided that the raw cotton winds the stirring rollers, cotton batting which leaks down can be recycled again, and waste of the raw cotton is avoided.

Description

technical field [0001] The utility model relates to the technical field of cotton thread weaving, in particular to a four-roller raw cotton opening and impurity removal device for weaving. Background technique [0002] Raw cotton is a fiber mass obtained by separating the fiber from the cottonseed through ginning. In order to facilitate the transportation of raw cotton, the raw cotton will be compressed to 330-400kg / m 3 Therefore, before spinning, it is necessary to open and remove impurities from the raw cotton. Opening is the process of breaking up large fiber clusters and blocks into small pieces and small bundles, so as to create a better way for further loosening to a single state in the future. Conditions, and in the process of opening, additional functions such as mixing, impurity removal, and dust removal will also occur. [0003] The traditional opening machine firstly stirs and tears the raw cotton through the stirring roller, and then further beats the raw cotton...

AI Technical Summary

Problems solved by technology

[0003] The traditional opening machine firstly stirs and tears the raw cotton through the stirring roller, and then further beats the raw cotton to realize the opening of the raw cotton. The process is cumbersome and the efficiency is low. Raw cotton is easy to lift and wrap the entire stirring roller, and it is prone to entanglement, which makes the stirring roller unable to rotate normally. The general impurity removal device uses negative air pressure and filtering device to suck out impurities and remove them during the opening process of raw cotton. collection, but in the process of absorbing impurities, part of the raw cotton will also be sucked away, resulting in waste of raw cotton
