A kind of automatic silk clearing recovery spinning machine

Abstract

The invention discloses a spinning machine with a function of automatically cleaning silks. The spinning machine comprises a rack, a glue-supply spinning-jetting mechanism, a hotbox, a broken silk sensor, a twisting mechanism and a winding mechanism, wherein the glue-supply spinning-jetting mechanism, the hotbox, the broken silk sensor, the twisting mechanism and the winding mechanism are arranged on the rack; the glue-supply spinning-jetting mechanism comprises a glue supply pipe and a spinneret plate connected with the glue supply pipe, and the spinneret plate is arranged in the hotbox; the broken silk sensor is arranged on the outer side of a silk outlet of the hotbox and is used for detecting whether the silks are broken; a broken silk treatment assembly and a silk recovery box are arranged at the bottom of the hotbox, a heater and a spinning solution recovery pipe are arranged on the silk recovery box, and the spinning solution recovery pipe is communicated with the glue supply pipe; the winding mechanism is arranged below the twisting mechanism. According to the spinning machine with the function of automatically cleaning the silks, which is provided by the invention, due to arrangement of the broken silk sensor, the broken silk treatment assembly and the silk recovery box, the broken silk sensor is used for detecting whether the silks are broken, the broken silks are immediately cleaned by the broken silk treatment assembly after the broken silks are found, and the silks are recovered and reutilized.

Description

technical field [0001] The invention relates to the field of spinning equipment, in particular to an automatic silk cleaning recovery spinning machine. Background technique [0002] A spinning machine is a machine that forms a fiber-forming polymer solution or melt into filaments. According to different fiber spinning methods, the spinning machine is divided into three types: wet spinning machine, melt spinning machine and dry spinning machine. [0003] The dry spinning machine usually includes a spinning mechanism, a hot box and a winding mechanism, which sprays the spinning dope out of the fine spinning by means of the spinning mechanism, and is heated and shaped by the hot box, and then the spinning is twisted and rolled. winding to produce spinning products of various materials and specifications. [0004] There are still many problems in the production process of the existing dry spinning machine: after the spinning comes out of the hot box, due to the sudden drop in ...

AI Technical Summary

Problems solved by technology

[0004] There are still many problems in the production process of the existing dry spinning machine: after the spinning comes out of the hot box, due to the sudden drop in temperature, the spinning is easy to break at the spinning outlet of the hot box, which will seriously cause the line of defense. Accumulated in the hot box, while the winding mechanism is idling, resulting in a high waste yarn rate, if the spinning accumulated in the hot box is not cleaned in time, it will also block the spinning outlet of the hot box; most of the waste yarn after cleaning It is directly discarded, resulting in a waste of materials. The current dry spinning machine has no means to remelt the waste silk for recycling.

In addition, the twist stoppers used for twisting in existing dry spinning machines are mostly directly installed at the spinning outlet of the hot box. Due to the high temperature here, it is usually above 45°C, and the miniature twist stoppers Bearings are easily deformed by heat in a high temperature environment, which greatly reduces their service life. At present, the twist stopper of the existing dry spinning machine only has a service life of about 10 months, while its designed service life is about 3 years , which requires frequent replacement of twist stoppers, which not only increases material consumption, but also affects production efficiency
