A high-efficiency cotton opening machine for refined cotton

Abstract

The invention relates to the technical field of refined cotton and discloses a refined cotton opening machine high in cotton opening efficiency. The refined cotton opening machine high in cotton opening efficiency is used for decomposing a cotton package (9) into sheet matter or floccule. The refined cotton opening machine high in cotton opening efficiency comprises a feeding device, a defibering device and a feeding plate (1) arranged between the feeding device and the defibering device. The defibering device comprises at least two stages of defibering rollers used for defibering of the cotton package (9), the defibering rollers are sequentially arranged in a staggered mode from the feeding end to the discharging end, defibering teeth are arranged on the outer layers of the defibering rollers, the defibering device comprises the two stages of defibering rollers used for defibering of the cotton package (9), the defibering rollers are composed of the first-stage defibering roller (2) and the second-stage defibering roller (3), and a pre-pressing roller (4) is arranged between the first-stage defibering roller (2) and the second-stage defibering roller (3). By means of the refined cotton opening machine high in cotton opening efficiency, defibering efficiency is improved, the labor intensity of workers is lowered, and it is also guaranteed that defibering quality meets the technological requirement.

Description

technical field [0001] The invention relates to the technical field of refined cotton, in particular to a cotton opener. Background technique [0002] Cotton fiber is an important textile raw material. In order to facilitate transportation, manufacturers generally compact cotton fiber into a square cotton bale and sell it to users. When users use it, they must use a cotton opener to decompose the cotton bale into sheets. or flocs. The existing refined cotton opener is a traditional structure such as figure 1 As shown in the figure, it is composed of three parts: belt conveyor, feeding plate, and loosening roller. The cotton bales enter the feeding plate through the belt conveyor and perform linear motion, while the loosening roller for decomposing the cotton bales rotates and passes through the cotton bales. The weight of the bag itself is used as the pressing force, and the nail teeth on the loosening roller slowly loosen the packed cotton material. Although the structur...

AI Technical Summary

Problems solved by technology

The existing debonding roller adopts a detachable circular nail-tooth structure, which has complicated manufacturing process and low service life, and because the rotation accuracy of the deflaking roller is poor, in order to avoid interference, the gap between the nail teeth and the feeding plate is usually large, resulting in a large amount of The tail flower can not be relieved

During the defrosting process, the cotton material will also wrap the nail teeth, passivate the nail teeth, and increase the defibration resistance, resulting in insufficient defrosting layers and poor defrosting effects

[0006] Due to the above problems, in actual operation, in order to ensure the effect of defrosting, the only way to reduce the amount of feed is to control the speed of the belt conveyor as much as possible to ensure the effect of defusing

And when unpacking, it is often necessary to manually disassemble the cotton bales into two layers, and place the feeding materials horizontally and staggered to reduce the amount of tailings and the frequency of blocking flowers. Even if these methods are adopted, the problem cannot be solved fundamentally, and the quality of defoliation still cannot meet the process requirements
