A kind of automatic cleaning waste liquid spinning machine

Abstract

The invention discloses a spinning machine with a function of automatically cleaning 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 is arranged at the bottom of the hotbox and is used for cleaning spinning solution flowing from the spinneret plate to a base plate of the hotbox; a wastewater recovery box is fixed at the base plate of the hotbox and is used for recovering the spinning solution cleaned out by the wastewater cleaning assembly; 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 the wastewater, which is provided by the invention, the wastewater cleaning assembly and the wastewater recovery box are arranged at the bottom of the hot box, and immediately clean and recover the spinning solution dropped from the spinneret plate, so that pollution of the spinning solution not cleaned for a long time to the interior of the hotbox can be prevented, 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 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 located in the...

AI Technical Summary

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; in addition, the twist stoppers used for twisting of existing dry spinning machines are mostly directly installed at the spinning outlet of the hot box, because here The temperature is high, usually above 45°C, and the miniature bearing of the twist stopper is easily deformed by heat in a high temperature environment, which greatly reduces its service life. At present, the twist stopper of the existing dry spinning machine is only about The service life of 10 months, and its design service life is about 3 years, which requires frequent replacement of the twist stopper, which increases material consumption and affects production efficiency
