a spinning device

Abstract

The invention discloses a spinning device which comprises a rack, a glue supply spinneret mechanism, a heat box, a spinning yarn breakage sensor, a twisting mechanism and a coiling mechanism, wherein the glue supply spinneret mechanism, the heat box, the spinning yarn breakage sensor, the twisting mechanism and the coiling mechanism are arranged on the rack; the glue supply spinneret mechanism comprises a glue supply tube and a spinneret plate which is connected with the glue supply tube; the spinneret plate is arranged inside the heat box and sides of the spinneret plate are wrapped by copper edges; the spinning yarn breakage sensor is positioned on the outer side of a spinneret outlet of the heat box; the spinning yarn breakage sensor is used for detecting whether spinning yarn is broken or not; the twisting mechanism comprises a twisting stopper, a first yarn guider and a second yarn guider; the coiling mechanism comprises a rotating rack and a rotating rack driver; a pair of coiling rollers in parallel are arranged on the rotating rack. According to the spinning device disclosed by the invention, as the sides of the spinneret plate are wrapped by the copper edges, the thermal resistance of the spinneret plate can be improved; due to arrangement of the spinning yarn breakage sensor on the outer side of the spinning outlet of the heat box, the waste yarn rate is reduced; the twisting stopper is far away from the spinning outlet, so that the problems that the twisting stopper is short in service life and the like in the prior art as the twisting stopper is too close to the heat box is solved.

Description

technical field [0001] The invention relates to the field of spinning equipment, in particular to a spinning device. Background technique [0002] A spinning unit is a machine that forms a fiber-forming polymer solution or melt into filaments. According to different fiber spinning methods, the spinning device 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 set in a hot box for a long time, the spinneret is easily d...

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 set in a hot box for a long time, the spinneret is easily deformed due to long-term heating, which affects the spinning effect Seriously, it will also cause the spinneret hole to be blocked, which will affect normal production; after the spinning comes out of the hot box, due to the sudden drop in temperature, the spinning will easily break at the spinning outlet of the hot box, which will seriously cause the defense line to be in the heat. Accumulation in the box, while the winding mechanism is idling, resulting in a high waste yarn rate; in addition, the twist stoppers used for twisting in the existing dry spinning machines are mostly directly installed at the spinning outlet of the hot box. The temperature here 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 It has a service life of about 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
