Wool tops unwinding and feeding device

Abstract

The invention discloses a wool tops unwinding and feeding device and belongs to the field of textile processing mechanical equipment. An unwinding mechanism, a drafting mechanism and a tops guide mechanism are horizontally fixed to a fixture sequentially from top to bottom in the vertical direction; rolled wool bearing rollers are horizontally and rotationally connected to two sides above the fixture sequentially in the horizontal direction, an upper feeding plate, an upper drafting plate, a lower drafting plate and a lower discharging plate are horizontally arranged on one side of the fixturesequentially from top to bottom, a front bracing upper roll and a front bracing lower roll are horizontally and rotationally connected to a front bracing support sequentially from top to bottom, a rear gracing main roll and a rear bracing auxiliary roll are rotationally connected to each side of a rear bracing support sequentially in the horizontal direction, and a pneumatic conveying guide tubeis vertically communicated with the bottom of a collection hopper. The wool tops unwinding and feeding device is reasonable in structural design, allows drafting to be performed stably and evenly during unwinding and conveying of wool tops, and allows the drafted wool tops to be automatically braced and fed continuously and efficiently, so that the needs for production and use are met.

Description

technical field [0001] The invention belongs to the field of textile processing machinery and equipment, and in particular relates to a top unwinding and feeding device, which is mainly applied to the field of top drawing processing. Background technique [0002] Tops are slivers made of woollen raw materials. In the wool spinning process, wool fibers are first processed into tops, and then spun into wool. After combing and combing, the wool is combed and prepared and finished. , that is, the wool top is made. The process is worsted wool spinning. The wool spinning and combing process includes carding, sliver management, combing, whole sliver, rewashing, sliver refining, roving and spinning. The main process flow of the top processing is: the loose clean wool is made into tops by a carding machine, and most of the fibers in the tops are hook-shaped. Short fibers and residual weeds and hair particles that meet the process requirements are washed and dried to remove oil stain...

AI Technical Summary

Problems solved by technology

After the production and processing of wool tops in the previous process, the wool tops generally exist in the form of fine wool top rolls. Therefore, in the production and processing of wool tops in the subsequent process, the wool tops need to be unwound and transported. The existing wool top rolls have low unwinding efficiency. , it is difficult to efficiently drive the wool top roll to rotate and unwind, and the existing wool top roll unwinding mechanism is difficult to apply to wool top rolls of various sizes and specifications. After the wool top on the existing wool top roll is processed by the previous process, the wool top The fiber is not fully drawn, so it is necessary to draw the wool top evenly during the unwinding process of the wool top. It is difficult for the existing wool top processing mechanism to draft synchronously during the transmission of the wool top, and it is necessary to complete the unwinding of the wool top Afterwards, the drafting is carried out section by section, and the drafting efficiency of the wool top is low, and in the drafting process of the wool top, the existing wool top drafting device draws the wool top section by section, which easily causes each section of the wool top to be stretched. Both ends are over-drawn and the middle part of the wool top is not sufficiently drawn, so it is difficult to draw the wool top continuously and reciprocally evenly, and the drafting quality of the wool top is also poor. When wool tops are processed into shorter length wool tops, a cutting knife is mainly used to cut the wool tops section by section. After the wool tops are cut by the cutting knife, not only will the wool top fibers be damaged, but also the length of the wool top fibers will be shortened, resulting in The quality is reduced, which affects the production and processing quality of wool tops, and cannot meet the needs of production and use.
