Description

Technical Field

[0001] The utility model relates to the technical field of filter cloth production, and particularly relates to a needle punching forming device for PPS fiber filter cloth. Background Art

[0002] The PPS fiber filter cloth is made of polyphenylene sulfide fiber as the main raw material. Polyphenylene sulfide is a kind of high molecular polymer. The PPS fiber is spun into fiber bundles by a spinning machine, and then the fiber bundles are woven into filter cloth by a loom. Then, the filter cloth is subjected to needle punching treatment to increase its thickness and density, so as to improve the filtering performance. After that, singeing treatment is carried out to remove impurities and burrs on the surface of the filter cloth and make its surface smoother. Finally, sizing treatment is carried out to make the filter cloth reach the ideal size and shape. However, there are some problems in the traditional PPS fiber filter cloth production equipment. For example, the fiber distribution is uneven during the needle punching process, which affects the strength and tightness of the filter cloth. In order to solve the above problems and improve the efficiency and quality of filter cloth needle punching, the utility model comes into being. Content of the Utility Model

[0025] Working principle:

[0026] During use, the base 1 is fixed to the ground as the base of the overall equipment. The PPS fiber raw material is fed between the wire mesh plates 24 through the feeding roller 25 in the needle punching device 2. Then, the hydraulic rod 21 drives the needle punching plate 22 to reciprocate up and down. The needles 23 on the needle punching plate 22 repeatedly puncture the fiber layer, causing the fibers to entangle with each other, thereby enhancing the strength and tightness of the PPS fiber filter cloth;

A uniform roller 35 is connected through a lead screw 33 and a carriage 34. The uniform roller 35 cooperates with the feeding roller 25 to evenly comb the PPS fiber raw material, so that the PPS fiber raw material is dispersed and evenly enters between the wire mesh plates 24 for better needle punching work. When it is necessary to adjust the distance between the uniform roller 35 and the feeding roller 25, start the drive motor 31. The drive motor 31 drives the carriage 34 to move through the lead screw 33, and the carriage 34 drives the uniform roller 35 to move, thereby adjusting the distance from the feeding roller 25;
