Problems solved by technology

[0003] In the process of use, due to the fixed shape of the spinning structure, only one cross-sectional shape of chemical fiber can be produced. When it is necessary to produce chemical fiber of other cross-sectional shapes, it is necessary to install the spinneret on the chemical fiber spinning machine. Remove and replace the spinnerets with different cross-sectional shapes, and because the spinnerets work under high temperature conditions, for safety, it is usually necessary to close the spinning machine, and then disassemble and replace the spinnerets after they cool down to a safe temperature. The first process is very time-consuming, which leads to the reduction of production efficiency, so to solve this problem, we need a special spinneret for the production of velvet and soft special-shaped fibers to solve this problem

Embodiment 1

[0029] refer to Figure 1-4 , a special-purpose spinneret for the production of velvet soft special-shaped fibers, including a front cover 1, a back cover 2, and a spinneret body 4. The back cover 2 is connected to the front cover 1 through bolts 201, and the spinneret body 4 is rotatably connected to the front cover. 1 and the back cover 2, the front cover 1 is sealed with a box body 101, the box body 101 and the front cover 1 form a hollow cavity 1011, the box body 101 is connected with a feeding pipe 102, and the spinneret body 4 is arranged in turn. There are a first special-shaped hole 404 and a second special-shaped hole 405, and the rear cover 2 is provided with a discharge hole 202. When in use, the raw material is transported into the box body 101 through the delivery pipe 102, and first processed and formed through the first special-shaped hole 404 , when holes with different cross-sections are required, the spinneret body 4 is rotated between the front cover 1 and t...

Embodiment 2

[0031] refer to Figure 1-4 , a special-purpose spinneret for the production of velvet soft special-shaped fibers, which is basically the same as that of Embodiment 1, and furthermore, the front cover 1 is rotatably connected with a rotating shaft 301, and the spinneret body 4 is provided with a shaft hole corresponding to the rotating shaft 301 401, the upper end of the rotating shaft 301 is fixedly connected with the handle 3, the lower end of the rotating shaft 301 is connected with the spinneret body 4 through the shaft hole 401, and the limit key 302 is slidably connected on the rotating shaft 301, and the shaft hole 401 is provided with a position corresponding to the limit key 302. The keyway 402 drives the rotating shaft 301 to rotate by turning the handle 3 , so that the spinneret body 4 is driven to rotate by the limit key 302 .

Embodiment 3

[0033] refer to Figure 1-4 , a special-purpose spinneret for the production of velvet soft special-shaped fibers, including a front cover 1, a back cover 2, and a spinneret body 4. The back cover 2 is connected to the front cover 1 through bolts 201, and the spinneret body 4 is rotatably connected to the front cover. 1 and the back cover 2, the front cover 1 is sealed with a box body 101, the box body 101 and the front cover 1 form a hollow cavity 1011, the box body 101 is connected with a feeding pipe 102, and the spinneret body 4 is arranged in turn. There are a first special-shaped hole 404 and a second special-shaped hole 405, and the rear cover 2 is provided with a discharge hole 202. When in use, the raw material is transported into the box body 101 through the delivery pipe 102, and first processed and formed through the first special-shaped hole 404 , when holes with different cross-sections are required, the spinneret body 4 is rotated between the front cover 1 and t...

Abstract

The invention discloses a spinneret plate especially used for velvet soft specially-shaped fiber production and belongs to the fiber production field. The spinneret plate especially used for velvet soft specially-shaped fiber production comprises a front cover, a rear cover, and a spinneret plate body. The rear cover is connected to the front cover through a bolt. The spinneret plate body is rotatably connected between the front cover and the rear cover. A box body is sealed and connected to the front cover. The box body and the front cover form a hollow cavity. The box body is connected to afeed delivery pipe. The spinneret plate body is successively provided with a first specially-shaped hole and a second specially-shaped hole. The rear cover is provided with a discharge hole. In the invention, through the feed delivery pipe, a raw material is conveyed to the box body. Through the first specially-shaped hole, processing and forming are performed. When the holes with different crosssections are needed, the spinneret plate body is rotated between the front cover and the rear cover so that the processing and forming are performed through the second specially-shaped hole and outputis performed through the discharge hole.

Description

technical field [0001] The invention relates to the technical field of fiber production, in particular to a special-purpose spinneret for the production of velvet and soft special-shaped fibers. Background technique [0002] The spinneret is also called the spinning cap. The function of the spinneret is to transform the viscous polymer melt or solution into a thin stream with a specific cross-section through the micropores, and solidify it through a coagulation medium such as air or a coagulation bath. to form filaments; [0003] In the process of use, due to the fixed shape of the spinning structure, only one cross-sectional shape of chemical fiber can be produced. When it is necessary to produce chemical fiber of other cross-sectional shapes, it is necessary to install the spinneret on the chemical fiber spinning machine. Remove and replace the spinnerets with different cross-sectional shapes, and because the spinnerets work under high temperature conditions, for safety, ...
