Seed cotton foreign fiber separating and opening machine

Abstract

The invention relates to a seed cotton foreign fiber separating and opening machine for separating and removing a foreign fiber in a machine picked seed cotton processing link. The machine comprises a machine shell, wherein the upper part of the machine shell is provided with a feed opening and a discharge opening, and the lower part is provided with an impurity discharge opening; a fluidizing chamber comprising an upper cavity and a lower cavity is arranged in the machine shell; the volume of the upper cavity of the fluidizing chamber is larger than that of the lower cavity of the fluidizing chamber; the lower part in the fluidizing chamber is provided with a shifting rod disperser; the shifting rod disperser comprises a shifting rod which is vertically arranged at the bottom of the fluidizing chamber and an opening plate which is arranged on the shifting rod; the lower part of the fluidizing chamber is provided with an air inlet, the air inlet is connected with a fan; a mesh partition plate is arranged at the upper part of the air inlet in the fluidizing chamber; and an air stopping device is arranged near the feed opening in the fluidizing chamber. The invention has simple structure, production cost saving and good effects of seed cotton opening and foreign fiber separation, and can effectively prevent the damage to the seed cotton fiber by mechanical force action.

Description

Technical field: [0001] The invention relates to a seed cotton foreign fiber separating and loosening machine for separating and removing foreign fibers in the machine-harvested seed cotton processing link. Background technique: [0002] Foreign fibers in cotton refer to non-cotton fibers that are mixed into cotton during the production, processing and circulation of seed cotton and have a serious impact on the quality of cotton and its products, such as chemical fibers, hair, silk, plastic film, dyed thread, etc., colored Fiber, chemical fiber, and hair are commonly known as "three silks". Foreign fibers mixed into seed cotton are easily broken into scattered single fibers, which are difficult to remove in textile processing. During spinning, scattered single fibers are easy to break the cotton yarn and reduce production efficiency; during weaving, it affects the quality of the cloth surface; during dyeing, due to different coloring, it affects the appearance, causing grea...

AI Technical Summary

Problems solved by technology

Existing cleaning equipment for organic cotton harvesting cannot effectively remove foreign fibers such as residual film. At the same time, after multiple cleaning processes, the residual film is broken and mixed into lint, which increases the difficulty of subsequent textile enterprises to remove impurities.

[0004] From the perspective of domestic and foreign products currently on the market, the research on the separation and treatment of foreign fibers in cotton is mainly concentrated in the process of opening and cleaning lint in the textile industry after ginning, while the research on the separation of foreign fibers such as residual film of machine-picked seed cotton There are still few reports. At present, the sorting of machine-picked seed cotton residual film is mostly carried out manually, which is labor-intensive, time-consuming and labor-intensive, and seriously hinders the promotion process of machine-picked cotton technology.

Before cleaning the three-filament seed cotton, it generally needs to go through the preparation process of opening. The structure of the cleaning machine currently used is complicated, which increases the production cost.
