Spinning machine with function of automatically cleaning and recovering wastewater

Abstract

The invention discloses a spinning machine with a function of automatically cleaning and recovering wastewater. The spinning machine comprises a rack, a glue-supply spinning-jetting mechanism, a hotbox, a twisting mechanism and a winding mechanism, wherein the glue-supply spinning-jetting mechanism, the hotbox, 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; a wastewater cleaning assembly and a wastewater recovery box are arranged at the bottom of the hotbox, and the wastewater cleaning assembly is used for cleaning spinning solution, which flows from the spinneret plate to a base plate of the hotbox, into the wastewater recovery box; the wastewater recovery box is communicated with the glue supply pipe through a wastewater recovery pipe, and the wastewater recovery pipe is used for recovering the recovered spinning solution to the glue supply pipe; the twisting mechanism is located at a silk outlet of the hotbox; the winding mechanism is arranged below the twisting mechanism. According to the spinning machine with the function of automatically cleaning and recovering the wastewater, which is provided by the invention, due to arrangement of the wastewater cleaning assembly and the wastewater recovery box, the spinning solution dropped from the spinneret plate to a base plate of the hotbox is cleaned, and by utilization of the wastewater recovery pipe, the recovered spinning solution is directly recovered in the glue supply pipe, so that the automation degree is high, and raw materials are saved.

Description

technical field [0001] The invention relates to the field of spinning equipment, in particular to a spinning machine for automatically cleaning and recovering waste liquid. 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: because the spinneret of the spinning mechanism is...

Problems solved by technology

[0004] There are still many problems in the production process of the existing dry spinning machine: because the spinneret of the spinning mechanism is located in the hot box for a long time, and the hot air will be passed into the hot box to make the newly sprayed spinning finalize the shape, After a long time, the spinneret will be deformed, and the spinning effect of the deformed spinneret will become worse, and some spinning stock solution will directly drop from the spinneret to the bottom plate of the hot box. It will cause pollution to the hot box, and also cause a waste of spinning stock solution; the existing dry spinning machine basically uses regular shutdown to manually clean the spinning stock solution on the bottom plate of the hot box. This cleaning method not only affects normal production , which increases the labor intensity of workers

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
