Uniform cotton distributing system suitable for photoelectric sorting

Abstract

The invention discloses a seed cotton uniform distributing and sorting system suitable for photoelectric sorting. The system comprises a rack; a three-pipe cotton distributor is arranged on the rack; an air-lock valve is arranged below the three-pipe cotton distributor; a three-roller cotton distributing box is arranged below the air-lock valve; seed cotton thrown out by the three-roller cotton distributing box enters a cotton slipping ramp; a vertical cotton slipping channel is arranged below the cotton slipping ramp; and a photoelectric recognition and sorting box is arranged in the vertical cotton slipping channel. Foreign fibers and other impurities are hit and removed through a high-frequency electromagnetic valve, the seed cotton falls into a brush roller below the equipment, and the sorted seed cotton is discharged and enters a subsequent cotton ginning workshop. According to the invention, cotton balls conveyed along with a pipeline can be fully scattered, fine impurities such as dust, broken leaves and scrap iron wrapped in the cotton balls are primarily cleaned, and the seed cotton and the uncleaned foreign fiber impurities in the vertical cotton channel are conveyed at a constant speed through high-speed rotating airflow of the brush roller; and high-speed recognition and high-frequency sorting are carried out in the recognition and sorting box, so that other foreign fibers are removed, and the sorting precision is improved.

Description

technical field [0001] The invention relates to the technical field of cotton processing, in particular to a uniform cotton distribution system suitable for photoelectric sorting. Background technique [0002] At present, my country is a big cotton production and consumption country, and cotton processing and textile play an important role in the national economy. Due to the limitation of national conditions, there are problems of high content of foreign fibers and impurities in real estate cotton and machine-picked cotton. This problem has not been effectively solved for a long time, which has seriously affected the quality of cotton yarn and cloth surface, and has become a major problem recognized by my country's textile industry. [0003] Before the impurity removal process of seed cotton, the transportation of seed cotton and the uniform cotton distribution process are extremely important. Whether the cotton flow is loose or not is related to whether foreign fibers can ...

AI Technical Summary

Problems solved by technology

[0004] In the existing cotton blending technology, most of the cotton blending equipment used for photoelectric sorting is difficult to efficiently cooperate with the cotton processing technology, especially the key technologies such as uniform blending of seed cotton, initial cleaning of impurities, and cotton flow control greatly affect photoelectric sorting promotional use of

In addition, the existing photoelectric foreign fiber machine is basically for the identification and sorting of foreign fibers in lint cotton. The identification and sorting technology of foreign fibers in seed cotton is rarely reported. The important reason is that the pretreatment process of seed cotton is complicated, and various impurities in it Difficult pretreatment, if all kinds of dust, iron filings, broken leaves and other impurities cannot be effectively removed, photoelectric separation will be difficult to achieve the expected effect
