Description

Technical Field

[0001] This utility model relates to the field of spinning processing technology, specifically to a melt filter for spinning processing. Background Technology

[0002] Spinning, also known as fiber forming, is a continuous, quantitative, and uniform process. In this process, the spinning fluid (such as polymer melt or solution) is steadily extruded from the capillary pores of the spinneret or spinneret by the propulsion of a spinning pump (also known as a metering pump), forming liquid fine streams. Subsequently, these liquid fine streams undergo solidification in air, water, or a coagulation bath, eventually becoming filaments. During processing, a melt filter is used, which is an important piece of equipment for high-speed spinning and spinning fine denier filaments. It is used for continuous filtration of polymer melts to remove impurities and unmelted particles from the melt, thereby improving the spinning performance of the melt and ensuring the quality of spinning.

[0003] According to a novel spinning melt filter with application number CN202022866172.0, this solution addresses the issues of small footprint, easy operation, flexible switching between different spinning varieties, and low consumable costs.

[0004] However, the following problems still exist in actual use:

[0005] (1) When in use, the material is discharged only through the melt outlet. There is no effective flow regulation mechanism. The melt outlet flow rate cannot be flexibly adjusted according to production needs, resulting in unstable flow rate during production discharge, affecting product quality, and making it difficult to carry out more efficient operation in reality.

[0006] (2) When in use, the filter screen is tightly connected to the inner wall of the filter section, and the disassembly of the filter screen requires complicated operation steps, which increases the difficulty and time cost of maintenance. In addition, under high temperature and high pressure working environment, the filter screen is easily corroded and blocked by the melt, and needs to be replaced frequently. It cannot meet the need for quick replacement when in use, which affects production efficiency.

[0007] Therefore, this utility model introduces a melt filter for spinning processing. Utility Model Content

[0017] 1.

A first guide plate 3 is fixedly installed at the bottom of the interior of the housing 1, and a second guide plate 4 is fixedly installed on the right side of the interior of the housing 1. The L-shaped fixing plate 5, screw 6, connecting rod 7, sleeve 8, control plate 9, and hand-tightening bolt 10 are used to adjust the filter. The use of the first guide plate 3 and the second guide plate 4 can achieve a more precise and efficient material discharge in reality, avoid the problem of unstable flow during the production process, improve the overall quality, and facilitate more efficient operation in reality.

[0026] Please refer to Figure 4. The housing 1 has an internal dismantling mechanism 21, which includes a top cover 11, a filter cartridge 14, a connecting plate 15, a limiting screw 16, and a T-shaped plate 17. The outer surface of the top cover 11 is fitted to the interior of the housing 1. The top of the filter cartridge 14 abuts against the bottom of the top cover 11. The right side of the connecting plate 15 abuts against the outer surface of the filter cartridge 14. The outer surface of the limiting screw 16 is threaded into the interior of the connecting plate 15. The outer surface of the T-shaped plate 17 is inserted into the interior of the connecting plate 15, and the bottom of the T-shaped plate 17 is fitted to the top of the top cover 11. The outer surface of the limiting screw 16 is threaded into the interior of the filter cartridge 14. A first limiting bolt 18 is installed on the internal thread of the T-shaped plate 17, and the outer surface of the first limiting bolt 18 is threaded into the interior of the connecting plate 15. A second limiting bolt 19 is installed on the internal thread of the T-shaped plate 17, and the outer surface of the second limiting bolt 19 is threaded into the top cover 11. The internal threaded connection, through the use of the top cover 11, filter cartridge 14, connecting plate 15, limit screw 16, T-shaped plate 17, first limit bolt 18, and second limit bolt 19, can achieve the effect of easy and quick disassembly of filter cartridge 14, meet the need for quick replacement of filter cartridge 14, and avoid the impact on production efficiency.

[0027] Please refer to Figures 1 and 2. The outer casing 1 has a discharge port 2 inside. The filtered melt can be discharged through the discharge port 2 to achieve convenient collection. The top cover 11 has a feed hole 12 in the center of its surface. The top cover 11 has mounting holes 13 around its perimeter. The feed hole 12 and mounting holes 13 can be used to conveniently put the melt in and out, as well as connect the whole to external equipment.

[0028] Working principle: During use, when filtering the melt, the mounting hole 13 is opened inside the top cover 11 to connect the outer shell 1 to the external equipment. Then, the melt is fed into the interior of the outer shell 1 through the feed hole 12. After the melt enters the interior of the outer shell 1, the filter cylinder 14 inside the outer shell 1 removes impurities from the melt. The filtered melt is then guided out by the first guide plate 3 fixed to the bottom of the interior of the outer shell 1 and the second guide plate 4 fixed to the right side of the interior of the outer shell 1. When controlling the discharge, the back of the hand-tightening bolt 10 can be removed from the outer surface of the outer shell 1, and then the screw 6 can be rotated, causing the connecting rod 7 fixed to the outer surface of the screw 6 to rotate. When the connecting rod 7 rotates, the position of the control plate 9 can be changed synchronously inside the outer shell 1. After the position of the control plate 9 is changed, the hand-tightening bolt 10 can be tightened again on the screw 6. The outer surface of the control plate 9 is rotated to make it come into contact with the outer surface of the outer shell 1, thereby limiting the rotation of the control plate 9 and controlling the discharge of the filtered melt accordingly.

[0029] When easily disassembling the filter cartridge 14, first remove the second limiting bolt 19 and the first limiting bolt 18 from the inside of the top cover 11 and the connecting plate 15. Then, remove the T-shaped plate 17 from the inside of the connecting plate 15. Next, pull the T-shaped plate 17 out from the upper surface of the top cover 11. There is no corresponding limiting force between the top cover 11 and the inside of the outer shell 1, allowing the top cover 11 to be removed from the inside of the outer shell 1. Finally, remove the limiting screw 16 from the inside of the connecting plate 15 and the filter cartridge 14. This separates the filter cartridge 14 from the bottom of the top cover 11, allowing for the replacement of the filter cartridge 14. During installation, first abut the top of the filter cartridge 14 against the bottom of the top cover 11, then abut the right side of the connecting plate 15 against the outer surface of the filter cartridge 14. After that, install the limiting screw 16 inside the connecting plate 15, with the outer surface of the limiting screw 16 against the filter cartridge 14. The internal components are connected, and then the top cover 11 is installed on the outer surface of the connecting plate 15, with the outer surface of the top cover 11 abutting against the inside of the outer shell 1. Then, the T-shaped plate 17 can be inserted into the inside of the connecting plate 15, with the bottom of the T-shaped plate 17 fitting against the top of the top cover 11. Finally, the first limiting bolt 18 is installed on the inside of the T-shaped plate 17 and the connecting plate 15, and the second limiting bolt 19 is installed on the inside of the top cover 11 and the T-shaped plate 17, ensuring the stability of the filter cartridge 14 during use and the ease of disassembly.
