[0024] The cleaning structure includes a plurality of guide slide bars 61. The two guide slide bars 61 on the same side are respectively slidably mounted on the two cleaning boxes 6. The two ends of the two guide slide bars 61 are respectively fixedly mounted with mounting rods 62 and scraping blocks 63. The two scraping blocks 63 are respectively in contact with the two tension control rollers 5. The inner walls of the two cleaning boxes 6 are fixedly mounted with suction pipes 64. The two suction pipes 64 correspond to the two tension control rollers 5 respectively. The two cleaning boxes 6 are fixedly mounted with conveying pipes 65. The two conveying pipes 65 are respectively connected with the two suction pipes 64. The two conveying pipes 65 are fixedly mounted with fans 66. The two fans 66 are respectively fixedly mounted on one side of the two support frames 3. A recovery pipe 67 is fixedly installed on each of the two fans 66, and a recovery frame 68 is fixedly installed at one end of each of the two recovery pipes 67. The two recovery pipes 67 are respectively connected to the two recovery frames 68. Recovery boxes 69 are movably installed on the inner walls of the two recovery frames 68. Ventilation filter plates 610 are fixedly installed on the inner walls of the two recovery boxes 69. A limiting hole 41 is provided on the movable connecting rod 4, and a limiting shaft 42 is rotatably installed in the limiting hole 41. The limiting shaft 42 is fixedly installed on one side of the support frame 3. Linkage holes 81 are provided at both ends of the connecting rod 8. Linkage shafts 82 are rotatably installed in the two linkage holes 81. The two linkage shafts 82 are respectively fixedly installed on the movable connecting rod 4 and At the output end of the tension control cylinder 7, two positioning slots 611 are provided on the recovery frame 68, and positioning slide blocks 612 are movably installed in the two positioning slots 611.

One end of the spring 613 is fixedly installed on one side of the scraper block 63, and the other end of the spring 613 is fixedly installed on the inner wall of the cleaning box 6. By controlling the extension and contraction degree of the tension control cylinder 7, the squeezing force of the tension control roller 5 can be adjusted to achieve the effect of adjusting the tension of the non-woven fabric, and the non-woven fabric will generate friction with the tension control roller 5 during the production movement. Thereby, the tension control roller 5 is driven to rotate, and the rotating tension control roller 5 will contact the scraper block 63, so that the scraper block 63 can scrape off the impurities attached to the tension control roller 5, and a spring 613 is sleeved on the guide slide bar 61, and the spring 613 can squeeze the scraper block 63 so that it can stick to the surface of the tension control roller 5, thereby improving the scraping effect.

[0025] The working principle is as follows: during use, the nonwoven fabric can be passed through between the two tension control rollers 5, and the output end of the tension control cylinder 7 can be controlled to extend and retract by opening the two tension control cylinders 7. When the output end of the tension control cylinder 7 extends and retracts, it will drive one end of the connecting rod 8 to flip and move through the corresponding linkage hole 81 and the linkage shaft 82, so that the other end of the connecting rod 8 pulls or pushes one end of the movable connecting rod 4 to flip. When the movable connecting rod 4 flips, it will rotate on the restriction shaft 42 through the restriction hole 41, so that the movable connecting rod 4 can achieve the flipping effect. The continuously flipped movable connecting rod 4 will The two tension control rollers 5 are driven to move, so that the tension control rollers 5 can be squeezed on the non-woven fabric. The squeezing force of the tension control rollers 5 can be adjusted by controlling the extension and contraction degree of the tension control cylinder 7, so as to achieve the effect of adjusting the tension of the non-woven fabric. In the process of production and movement, the non-woven fabric will generate friction with the tension control rollers 5, thereby driving the tension control rollers 5 to rotate. The rotating tension control rollers 5 will contact the scraper block 63, so that the scraper block 63 can scrape off the impurities attached to the tension control rollers 5. The guide slide bar 61 is sleeved with a spring 613, which can squeeze the scraper block 63 so that it can stick to the tension control The surface of the system roller 5 is improved to improve the scraping effect. During the process, the corresponding fan 66 can be turned on. The fan 66 can use the conveying pipe 65 and the suction pipe 64 to suck out the scraped impurities, and then transport them to the recovery box 69 on the recovery rack 68 through the recovery pipe 67. By setting the ventilation filter plate 610, ventilation can be carried out, and at the same time, impurities are blocked and stored in the recovery box 69. After that, only the recovery box 69 needs to be pulled out from the recovery rack 68 to clean the internal impurities. By setting the positioning slide groove 611 and the positioning slider 612, the recovery box 69 can be prevented from shifting during the installation process. By turning on the adjustment motor 9, the screw rod 91 can be driven to rotate. The rotating screw rod 91 will drive the linkage slider 92 to slide by cooperating with the threaded hole 94. The sliding linkage slider 92 will slide in the guide slide groove 95, thereby limiting the sliding direction of the linkage slider 92. The continuously sliding linkage slider 92 will drive the fixed plate 93 to slide, so that the fixed plate 93 can drive the two support plates 2 to slide on the bottom plate 1, and then the moving support plate 2 drives the support frame 3 to move, and finally achieves the effect of adjusting the position of the two tension control rollers 5, so as to adjust to the appropriate position according to the length of the non-woven fabric for tension control.

A fixing plate 93 is fixedly mounted on one side of the linkage slider 92, and the fixing plate 93 is slidably mounted on the top side of the bottom plate 1. The fixing plate 93 is fixedly mounted on the side where the two support plates 2 are close to each other. A threaded hole 94 is provided on the linkage slider 92, and the screw rod 91 is threadedly mounted in the threaded hole 94. A guide hole 94 is provided on the bottom plate 1. The linkage slider 92 is slidably installed in the guide slide groove 95. By turning on the adjustment motor 9, the screw rod 91 can be driven to rotate. The rotating screw rod 91 will drive the linkage slider 92 to slide by cooperating with the threaded hole 94. The sliding linkage slider 92 will slide in the guide slide groove 95, thereby limiting the sliding direction of the linkage slider 92. The continuously sliding linkage slider 92 will drive the fixed plate 93 to slide, so that the fixed plate 93 can drive the two support plates 2 to slide on the bottom plate 1, and then the moving support plate 2 drives the support frame 3 to move, and finally achieves the effect of adjusting the position of the two tension control rollers 5, so as to adjust to the appropriate position according to the length of the non-woven fabric for tension control.
