Pimple-free silk falling method applied to semi-continuous spinning machine

Abstract

The invention belongs to the field of semi-continuous spinning, and in particular discloses a pimple-free silk falling method applied to a semi-continuous spinning machine, which comprises the following steps of: A, breaking silk; B, sucking the silk into a silk suction device by adopting the silk suction device; C, taking a spinning cake out; and D, reversing the head. In the invention, the conventional silk falling method for the semi-continuous spinning machine is changed, and security problem caused by the use of iron cutters in silk falling is solved. Through pimple-free silk falling technology of the invention, a process of scraping silk waste pimples by using the iron cutters in the silk falling is saved, silk falling time is shortened, silk waste produced in the silk falling is reduced, the quality problem, caused by the silk waste produced by scraping the silk waste pimples in the silk falling, of rough pimpled silk is simultaneously solved, and the silk waste is directly sucked into a silk waste bucket.

Description

technical field [0001] The invention belongs to the field of semi-continuous spinning, and specifically relates to a lump-free doffing method suitable for a semi-continuous spinning machine. Background technique [0002] Doffing is a step of forming a silk cake after spinning (the silk sliver is spun in the centrifugal cylinder for a specified time, the silk sliver is interrupted, the silk cake formed in the centrifugal cylinder is taken out, and then the silk sliver is poured into the centrifugal cylinder Spinning process), the traditional doffing steps can be simply summarized as follows: first turn off the electric spindle - break the filament - wind the waste silk on the acid removal roller - lift the bracket - uncover the big cover of the drum - —Taking silk cakes—covering the big lid of the drum—pressing the bracket—turning on the electric ingot—scraping waste silk lumps—turning over. Specifically, after the silk sliver enters the centrifugal cylinder and is spun in t...

Problems solved by technology

Due to the current domestic and foreign semi-continuous spinning machines, when doffing, the filaments are first interrupted, and the filaments are wound on the high-speed rotating acid removal roller of the spinning machine to form large silk lumps, and then the filaments are poured into the centrifuge. Before pouring into the tank, it is necessary to scrape off the silk lumps with an iron knife, and when the iron knife scrapes the silk lumps, due to the high-speed rotation of the acid removal roller, the iron knife is easy to scratch the hands, arms, etc., causing safety hazards, and due to the semi-continuous spinning The filaments of the silk machine contain a large amount of water, and due to the machine specificity of the semi-continuous spinning machine, the suction force of the suction device used in the existing silk suction method is not strong enough to meet the requirement of sucking the waste silk. Require

[0003] The existing doffing method mainly has the following deficiencies: 1. The safety is poor. When doffing, it is necessary to use an iron knife to scrape the waste silk lumps wound on the pickling roller by rotating at high speed, which is not safe to scrape the waste silk lumps

Second, the doffing time is long, the doffing waste is much, and the production cost is high

3. The labor intensity is high, and the labor intensity of the car worker scraping the waste silk pimples during the doffing is high
