Spinning pack for phenolic resin fiber spinning machine

Abstract

The invention discloses a spinning pack for a phenolic resin fiber spinning machine. The spinning pack for the phenolic resin fiber spinning machine comprises a shell body, a connecting base and a spinneret plate, wherein the shell body is of a cylindrical shape, the spinneret plate is provided with through holes and is disposed on the bottom inside a cavity of the shell body 1, the middle of the connecting base is provided with a flow passage, and the upper end of the connecting base is fixedly connected on a material nozzle of the spinning machine. The spinning pack for the phenolic resin fiber spinning machine is characterized in that the upper portion of the spinneret plate inside the cavity of the shell body is sequentially provided with a filter screen, a guide plate, a distributing plate, a gland and a fastening screw barrel. The middle of the gland is fixedly connected with the lower end of the connecting base. The fastening screw barrel is fixedly connected with the upper portion of the shell body. The flow passage of the connecting base is sequentially communicated with corresponding through holes on the gland, the distributing plate, the guide plate, the filter screen and the spinneret plate. The spinning pack for the phenolic resin fiber spinning machine is simple in structure, convenient to use, easy to operate, and capable of timely filtering out large particulate matters in the process of spinning so as to prevent the blocking phenomenon of the through hole of the spinneret plate from occurring, prolong service life of the spinneret plate and guarantee production efficiency.

Description

[0001] technical field [0002] The invention relates to a phenolic resin fiber production equipment, in particular to a spinneret assembly for a phenolic resin fiber spinning machine. Background technique [0003] In the current phenolic resin fiber production process, the material is now melted and stirred, and then sent to the spinning machine by a metering pump for spinning. The spinning assembly used on the spinning box of the current spinning machine is a separate spinning There are through holes on the spinneret, and the material is extruded from these through holes under pressure to become a fibrous tow. The disadvantage of this spinneret is: because the molten liquid contains larger particles of materials or impurities , It is easy to block the through holes on the spinneret, resulting in frequent replacement of the spinneret and reducing production efficiency. Contents of the invention [0004] The object of the present invention is to provide a spinnere...
