A cotton opener for textile

Abstract

The invention discloses a cotton opening machine for textile, which comprises a cotton feeding mechanism, a pre-loosing mechanism and an opening mechanism; the pre-loosing mechanism and the opening mechanism are sequentially arranged after the cotton feeding mechanism, The pre-releasing mechanism includes a first pre-releasing roller group and a second pre-releasing roller group; the first pre-releasing roller group and the second pre-releasing roller group include an independent upper roller body and a lower roller body, and the lower roller body is Needle rollers of different specifications; and the opening mechanism includes a closed cylinder, and the closed cylinder is provided with a cotton opening roller, and the cotton opening roller includes a rotating shaft and a frame disc bracket arranged on the rotating shaft. , and a plurality of opening assembly assembling plates are uniformly formed on the frame disc support, and the opening assembly assembly plate is hinged with an opening structure with a swing arm. The invention can effectively improve the opening efficiency and opening effect of cotton opening.

Description

technical field [0001] The invention relates to the field of cotton raw material processing equipment in the textile industry, in particular to a cotton opener for textiles. Background technique [0002] It is generally believed that the cotton spinning process generally refers to the spinning process of extracting and pre-processing the cotton fibers in the raw cotton after picking, and then processing it into cotton yarn and cotton thread. In order to facilitate transportation of cotton raw materials before processing, it is usually transported to the textile factory in the form of baling raw cotton bales. The raw cotton bales are in a compacted state, and their packing density is usually 300-600kg / m2. 3 , Cotton in this compacted state usually needs to be opened before processing, to loosen the compressed and entangled fiber raw materials, to loosen and fluff the cotton mass, and to improve the toughness of the cotton fiber to facilitate spinning. High-quality spun yarn;...

Problems solved by technology

[0003] Traditional cotton opening is usually carried out by hand. After the cotton is torn by hand, it is tapped with a wooden stick with a thorn needle or loosened with a bowstring. The opening effect is good, but the opening efficiency is low; while the mechanized Cotton opening is achieved by a cotton opener. The roller on the cotton opener is the most direct key component that determines the opening effect and directly determines the quality of cotton opening. However, the structure of the rollers in the opening carding machine in the prior art is too simple , the opening and carding effect on cotton is poor, and it is easy to cause insufficient cotton bulkiness, and multiple opening operations are required, resulting in a decrease in work efficiency. After the roll is shredded, it is flat on the conveyor belt, which increases the work intensity of the workers and reduces the production efficiency of the opener.
