Short fiber post-processing string-up device and short fiber post-processing string-up method

Abstract

The invention provides a short fiber post-processing string-up device and a short fiber post-processing string-up method. The short fiber post-processing string-up device comprises a creel, a yarn guide, an oil bath and a first drawing machine and is characterized in that a braided rope with treelike branches is horizontally laid on the upper surface of the yarn guide, a tail branch of the braided rope is wound on a guide roller, used for winding yarns, of the yarn guide, a secondary tail branch of the braided rope is arranged in the oil bath in a forked manner, and the end of the braided rope is wound a drawing roller, used for drawing the yarns, of the first drawing machine. The short fiber post-processing string-up device and the short fiber post-processing string-up method have the advantages that when the device simple in structure is used, the braided rope is divaricated into a plurality of treelike branches corresponding to number of strands according to needs, the branches are connected with ends of the strands, and keeping drawing under a certain tension can be realized by demanding of one operator pulling the end of the rope and another operator helping to spread yarn sheets, so that manpower is greatly reduced, and waste of raw materials is avoided.

Description

technical field [0001] The invention relates to a spinning-in device and method for post-processing of short fibers. Background technique [0002] The production of staple fiber usually goes through main processes such as spinning, winding, barrel dropping and post-processing. Through spinning, winding and falling into the barrel, the raw silk for a certain period of time is laid in the silk barrel according to certain rules. A certain number of raw silk in the silk barrel is called a batch. The purpose of post-processing is to combine these The raw silk in the barrel is drawn, shaped, crimped, cut and packaged to produce products suitable for further processing requirements of spinning. [0003] Pull out a silk head from each silk barrel belonging to the same batch of raw silk, put them side by side, and wind them around the equipment running at low speed according to certain rules under manual traction to complete the post-processing operation, which is called fresh head...

AI Technical Summary

Problems solved by technology

[0004] According to the difference of staple fiber equipment and process requirements, a batch of raw silk ends should be divided into several pieces before spinning (take 3 pieces as an example below), and each piece includes several bundles of raw silk (3 pieces respectively include 5, 9,5 bundles of raw silk), three operators are required to pull a piece of yarn each, and when encountering equipment that needs to pass through, someone needs to "relay" to complete it, which determines that more people are required to complete the spinning operation

[0005] At the same time, due to the manual pulling of the filaments during the threading process, it is difficult to establish the tension of the filaments as soon as possible. When the filaments without tension pass through the surface of high-temperature equipment, due to the nature of the polymer material, the filaments will become very stiff. It is difficult to pull, so it must be cut off at any time before continuing to pull to the next device

Usually, a head lift needs to be stopped several times to cut off the hard wires, which not only causes too much waste wires, but also increases the intensity and difficulty of the operation.
