Description

Technical Field

[0001] This utility model relates to the field of spinneret technology, specifically to a spinneret filter assembly. Background Technology

[0002] Spinnerets are key components used in the production of chemical fibers to extrude polymer melts or solutions into filaments through micropores. Spinnerets are usually thin metal plates covered with densely packed small holes. The shape, size, and distribution of these holes are carefully designed, and they are mostly made of materials such as stainless steel and nickel alloys. These materials have good corrosion resistance, high temperature stability, and mechanical strength, and can work stably for a long time in the complex environment of chemical fiber production.

[0003] The spinneret filter assembly is an important component of the melt spinning spinneret assembly. It is mainly used to filter impurities and unmelted particles in the polymer melt, ensuring the smooth progress of the spinning process and improving fiber quality. The polymer melt enters the spinneret filter assembly through the central feed hole. First, it is filtered by the filter screen to intercept impurities and unmelted particles. The melt after being filtered by the filter screen enters the distribution plate. Through many small holes on the distribution plate, the melt is evenly distributed to various parts. Then it is pressed onto the spinneret and finally extruded into fibers through the spinneret holes.

[0004] The prior art patent document CN215209713U provides a filter-type spinneret. This filter-type spinneret, by inserting a tool into the operating chamber and rotating the operating rod, causes the rotating chamber to rotate. This allows the rotating chamber to move downwards through the threaded connection between the inner circumferential wall of the threaded ring and the threaded groove. This further drives the extrusion ring downwards, causing the extrusion ring to stop extruding the extrusion rod. Then, through the tension of the spring, the extrusion rod is disengaged from the extrusion groove. The spinneret and the filter screen can then be pulled out of the installation chamber together, facilitating the subsequent cleaning of the spinneret and the filter screen.

[0005] The aforementioned prior art, although the spinneret filter can rotate the rotating chamber by rotating the operating lever, thereby moving the rotating chamber downwards and causing the extrusion rod to move downwards, and then the spring tension allows the spinneret and filter screen to be pulled out of the installation chamber together, facilitating personnel cleaning, has an overly complex structure during use. Moreover, the device is mostly located inside the housing and is subject to the extrusion force of the pressure plate. The use of a large number of delicate components can easily lead to damage, thus affecting the efficiency of production and processing. Therefore, we need a spinneret filter assembly.

The filter screen 306 is installed inside the support frame 302 via the sliding of the second slider 305, allowing for its installation and disassembly through sliding. After the support frame 302 is installed, the first screw 307 is passed through the fixing plate 303 and the first nut 308 and tightened by rotation, thus securing and reinforcing the support frame 302. This component design makes it very convenient for personnel to disassemble and clean the filter screen 306 without using complicated disassembly methods. The design is simple and increases the stability of the device.

[0021] Specifically, the melt box 1 is equipped with a pressing mechanism 4, and the installation assembly 5 is equipped with a spinneret body 6.

[0022] Through the above technical solution, the molten raw material can be transported into the melt box 1 by the setting of the feed pipe 2, and the raw material is filtered by the filter mechanism 3 by the pressing mechanism 4, and then extruded by the spinneret body 6.

[0023] Specifically, the melt box 1 forms a sliding structure with the first slider 301 and the support frame 302, and the support frame 302 is installed inside the melt box 1. The support frame 302 forms a fixed structure with the handle 304 through the fixing plate 303.

[0024] Through the above technical solution, the sliding of the first slider 301 can play the role of sliding installation of the support frame 302. The fixing plate 303 and handle 304 provided on the front of the support frame 302 can be easily pulled out by personnel, making it convenient to disassemble the support frame 302.

[0025] Specifically, the support frame 302 forms a sliding structure with the filter screen 306 through the second slider 305, and the filter screen 306 is installed inside the support frame 302.

[0026] Through the above technical solution, the filter screen 306 is slidably installed inside the support frame 302 by the second slider 305, thereby allowing it to be disassembled and installed by sliding, which facilitates the disassembly and cleaning of the filter screen 306 by personnel.

[0027] Specifically, the support frame 302 is fixed by a first screw 307 and a first nut 308, and there are two first screws 307.

[0028] By using the above technical solution, the first screw 307 passes through the fixing plate 303 and is rotated and tightened with the first nut 308, which can play the role of fixing and installing the support frame 302 and can strengthen it.

[0029] Specifically, the mounting frame 501 has a rotating structure with a rotating shaft 502 and a buckle 503, and there are two buckles 503.

[0030] With the above technical solution, the buckle 503 can be manually rotated, and the rotation of the rotating shaft 502 can drive the buckle 503 to rotate, thereby engaging and fixing it with the fixing bolt 504.

[0032] By using the above technical solution, the second screw 505 is passed through the mounting frame 501 and rotated and tightened with the second nut 506, which can reinforce the mounting frame 501 and prevent it from easily falling off.

[0033] Working principle: When using this spinneret filter assembly, firstly, manually rotate the first screw 307 to remove it from the first nut 308. Then, pull the handle 304 outward by hand. The sliding of the first slider 301 causes the support frame 302 to slide, thereby disassembling it. Then, pull the filter screen 306 outward. The sliding of the second slider 305 causes the filter screen 306 to slide synchronously, allowing for the disassembly and cleaning of the filter screen 306. When disassembling and maintaining the spinneret body 6, first rotate the second screw 505 to remove it from the second nut 506. Then, manually rotate the buckle 503. The rotation of the rotating shaft 502 causes the buckle 503 to rotate, separating it from the fixing bolt 504. This allows the installation frame 501 to be disassembled. The spinneret body 6 is installed in the groove inside the installation frame 501, thus removing the spinneret body 6 along with the installation frame 501. This completes all the work.
