Double-cotton-box cotton storing and feeding device

Abstract

Disclosed is a double-cotton-box cotton storing and feeding device. The double-cotton-box cotton storing and feeding device is characterized in that the double-cotton-box cotton storing and feeding device is composed of at least two pneumoelectric hybrid control dust discharging type cotton storing boxes which are the same in structure and arranged in parallel front and back, and an air return area arranged around the front cotton storing box and the rear cotton storing box; the front and rear cotton storage boxes comprise front and rear cotton storage box inner cavities defined by left and right inner surrounding plates, front and rear mesh plates, middle mesh plate partition plates and cotton feeding rollers located at the bottoms; a distribution baffle is arranged at the top of each middle mesh plate partition plate; the upper ends of the front and rear cotton storage box inner cavities communicate with a cotton inlet pipeline; the air return area is formed by a space defined by front, back, left and right outer surrounding plates, left and right inner surrounding plates, front and back mesh plates, an air return area top plate and an air return area bottom plate; and an air return pipe is arranged on the lower portion of the air return area opposite to one side of the cotton inlet pipeline.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to a cotton storage and feeding device with double cotton boxes suitable for cotton opening or cleaning equipment with the function of cotton box storage. Background technique [0002] Cotton opening or cleaning equipment is one of the main machines of the combined blowing and carding machine, which shoulders the functions of opening and removing impurities of raw materials. It is common practice to use airflow to feed material into opening or cleaning equipment. When the cotton opening or cleaning equipment adopts the airflow feeding method, the cotton storage box is an indispensable device for the cotton opening or cleaning equipment. [0003] National Utility Model Patent ZL2018 2 1129234.6 "A Gas-electric Mixed Dust-Exhausting Cotton Feeding Box Applicable to Cotton Openers or Weighing Machines" has listed two traditional cotton feeding box devices and a gas-electric hybrid Du...

AI Technical Summary

Problems solved by technology

The stripper of the cotton condenser separates the cotton condensed on the dust basket and drops it into the cotton box, and accumulates it in the cotton box to reach a certain amount of cotton storage. Because the cotton falls by its own weight, the cotton is not dense enough. , small output

At the same time, the cotton is unevenly distributed along the width of the machine, which is not conducive to the opening and removal of impurities on the rear machine

In addition, the traditional cotton box does not have the ability to remove dust, lint and fine impurities

[0005] Chinese patent ZL2018 2 1129234.6 "A Pneumatic-electric Mixed Controlled Dust Exhaust Type Cotton Feeding Box Applicable to Cotton Opener or Weighing Machine", describes a gas-electric mixed control dust-exhausted cotton feeding box device, horizontal storage Cotton is uniform and has a strong ability to remove dust, short fibers and small impurities. It overcomes the uneven horizontal storage of cotton in the traditional cotton box device, which cannot eliminate dust, short fibers and small impurities, and is not suitable for the cotton picking process requirements of spinning machines. disadvantages

However, when the production fluctuates greatly before and after the blowing-carding unit, the cotton storage capacity of the single cotton box is insufficient, the production stability and balance ability is weak, and the cotton supply fluctuations of the pipeline are fully exposed.
