Lint cotton pretreatment device

Abstract

The invention discloses a lint cotton pretreatment device, which relates to the technical field of foreign fiber detection and classification system matched devices. The device comprises a rack roller (6), wherein a plurality of bulges are distributed on the outer surface of the rack roller (6) and are used for hooking and pulling lint cotton to be treated in the rotating process of the rack roller (6). The cotton can be loosened through the loosening treatment of the device provided by the invention, and the elasticity can be recovered, so the foreign fiber can be totally or partial exposed onto the surface of the cotton as much as possible, and the identification, the detection and the metering of the cotton foreign fiber are favorably realized.

Description

technical field [0001] The invention relates to the technical field of matching devices for foreign fiber detection and classification systems, in particular to a lint pretreatment device capable of maintaining the shape of foreign fibers. Background technique [0002] Foreign fibers in cotton refer to non-cotton fibers and colored fibers that are mixed into cotton during the process of cotton picking, tanning and purchasing, which have a serious impact on the quality of cotton and its products, such as chemical fibers, hair, hemp rope, etc. Although the content of foreign fibers in lint is small, it has a serious impact on the quality of cotton textiles. Foreign fibers mixed into the leather surface are likely to break the cotton yarn and reduce production efficiency; when weaving, it affects the quality of the cloth surface; when dyeing, it affects the appearance and causes great harm to the quality of cotton yarn and cloth surface. Therefore, the on-line detection, measu...

AI Technical Summary

Problems solved by technology

In the traditional production process, the methods of loosening the extruded cotton balls mainly include beating with rods and direct airflow transmission, etc. However, this extruded cotton balls only rely on the blowing of rods It cannot be loosened, and the length of the fiber will be damaged if the blow is too heavy; it is difficult to loosen the clump even if it is transmitted by air flow, and the light in the cotton foreign fiber detection channel cannot penetrate the cotton layer, and the camera will not be able to identify the foreign fiber in it
