Cotton feeding roller component for rotor spinning machine

Abstract

The invention relates to a cotton feed roller component for a rotor spinning machine, which belongs to the technical field of texture and is used for solving the problem that a metallic roller is unfavorable for controlling strands. The cotton feed roller component comprises an electromagnetic clutch, a dust hood, a cotton feed roller bearing, a hand-operated button and a cotton feed roller. The improved roller shaft and cotton feed part are split assembling structures; the cotton feed part is an elastic rubber roller; the side of the hand-operated button of the roller shaft is provided with a rubber roller mounting section; and the rubber roller is sleeved on the rubber roller mounting section and is tightly matched with the rubber roller mounting section. The cotton feed roller component is characterized in that: 1. an elastic jaw is formed between the cotton feed roller and a cotton feed plate, can effectively control the strands and improve impurities removing efficiency and the evenness of the formed yarn; and 2. the elastic rubber roller is adopted to avoid the phenomenon that the metallic roller abrades the cotton feed plate due to automatic stop failure.

Description

technical field [0001] The invention relates to a textile machinery part, in particular to a cotton feeding roller assembly for a rotor spinning machine, which belongs to the technical field of textiles. Background technique [0002] At present, the structure of the feeding roller assembly used in the rotor spinning machine is as follows: Image 6 As shown, its composition includes electromagnetic clutch 2, dust cover 1, cotton feeding roller bearing 3, cotton feeding roller and manual button 9. Cotton feeding roller is made of roller shaft 4 and metal roller 16, wherein, the cotton feeding position is the key part of roller assembly. The cotton feeding part of the cotton feeding roller assembly of the rotor spinning machine has always been a metal roller with an integrated structure with the roller shaft, and a rigid jaw is formed between the metal roller and the metal cotton feeding plate. It has been found through long-term use practice and research that this steel jaw i...

Problems solved by technology

After long-term use practice and research, it is found that this kind of steel jaw is not good for controlling whiskers

like Figure 7 As shown, the sliver 11 is elliptical under the action of the metal roller, and the fibers on both sides of the sliver cannot be effectively controlled. Large, resulting in insufficient carding of fiber bundles, uneven transfer amount, resulting in uneven yarn evenness and quality decline

In addition, when the self-stop failure of the cotton feeding roller occurs, the metal roller will wear the cotton feeding plate, and the worn cotton feeding plate will further reduce the control force of the sliver, which will make the yarn evenness worse and the slubs will increase.
