[0032] With the above scheme: after starting the hydraulic cylinder 51, the hydraulic cylinder 51 drives the fixed frame plate 52 to move together with the motor 53, and the motor 53 drives the rotating shaft 541 and the guide roller 542 to move synchronously. The guide roller 542 further drives the ceramic heating body 543 and the heat-conducting shell 544 to move. With the mutual approach of the two heat-conducting shells 544.

[0033] The outer wall of the fixed frame plate 52 is slidably connected with a sliding frame rod 545 at both ends of one side of the outer wall, and the inner wall of one end of the sliding frame rod 545 is rotatably connected with a rubber ball 547. The side wall of the end of the sliding frame rod 545 away from the rubber ball 547 is fixedly connected with a tension spring 546, and the end of the tension spring 546 is fixedly connected to the outer wall of the fixed frame plate 52.

[0034] As shown in Figures 1 to 9 The end of the sliding frame rod 545 is provided with a flattening assembly 55, and the flattening assembly 55 includes a rotating plate 551 rotatably connected to the side wall of the end of the sliding frame rod 545 close to the tension spring 546, and the end of the rotating plate 551 away from the sliding frame rod 545 is rotatably connected with a sliding block 553.

[0035] The side of the fixed frame plate 52 close to the sliding frame rod 545 is provided with a strip-shaped slot 552 at both ends, and the outer wall of one end of the sliding block 553 is slidably connected to the inner wall of the strip-shaped slot 552. The side wall of the sliding block 553 is fixedly connected with a connecting rod 554, and the end of the connecting rod 554 away from the sliding block 553 is fixedly connected with a connecting frame plate 555.

[0036] The top of the connecting frame plate 555 is rotatably connected with a rotating rod 556, the outer wall of the bottom end of the rotating rod 556 is fixedly connected with a silica gel roller 557, the outer wall of the middle end of the silica gel roller 557 is rotatably connected with a rotating ring 558, and the outer wall of the rotating ring 558 is fixedly connected with four scraping strips 559.

[0037] With the above scheme: the sliding frame rod 545 drives the rotating plate 551 to move stably, the rotating plate 551 drives the sliding block 553 to slide along the inner wall of the strip-shaped slot 552, and the sliding block 553 moves towards the direction of the sliding frame rod 545. The sliding block 553 further drives the connecting rod 554 and the connecting frame plate 555 to move, so that the connecting frame plate 555 drives the rotating rod 556 and the silica gel roller 557 to move synchronously.

[0038] The side wall of the connecting frame plate 555 is provided with an auxiliary assembly 56, and the auxiliary assembly 56 includes a square plate 561 fixedly connected to the outer wall of one side of the connecting frame plate 555, a cross rod 562 slidably connected through one side of the square plate 561, a strip-shaped plate 569 fixedly connected to one end of the cross rod 562, and a cleaning strip 564 fixedly connected to one side of the strip-shaped plate 569 away from the cross rod 562.

[0039] With the above scheme: when the connecting frame plate 555 starts to move, the connecting frame plate 555 drives the square plate 561 to move forward together with the cross bar 562. The movement of the cross bar 562 makes the strip-shaped plate 569 move synchronously with the cleaning strips 564, so that the two cleaning strips 564 gradually approach and form effective contact. With the mutual approach of the cleaning strips 564, the fitting effect between the cleaning strips 564 and the heat-conducting shell 544 is significantly enhanced, which not only improves the compactness of the surface contact between the cleaning strips 564 and the heat-conducting shell 544, but also ensures the high efficiency of the cleaning process. Through this action, the cleaning strips 564 can more closely contact the surface of the heat-conducting shell 544, effectively remove dust, impurities or other accumulations thereon, and ensure the cleanliness of the heat-conducting shell 544.

[0040] The outer wall of the heat-conducting shell 544 is in contact with the side wall of the cleaning strip 564 on both sides, the strip-shaped plate 569 is fixedly connected to one side of the square plate 561 away from the cleaning strip 564, and one end of the extrusion spring 563 is fixedly connected to the side wall of the square plate 561.

[0041] The outer wall of the piston plate 565 is slidably connected with the square shell 566, one side of the square shell 566 is fixedly connected to the side wall of the square plate 561, and the outer wall of the square shell 566 is in communication with the strip-shaped shell 567.

[0042] With the above scheme: the airflow in the square shell 566 is compressed and guided into the strip-shaped shell 567 under the extrusion action of the piston plate 565. After the airflow passes through the strip-shaped shell 567, it is discharged outward through the air holes 568 thereon, forming a certain airflow pressure.

[0043] The working principle and use process of the present application are as follows:

[0044] The worker fixes the non-woven fabric cover on the outer wall of the workpiece 4 by ultrasonic welding technology, then places the workpiece 4 on the top of the conveying piece 3, clamps it between the two clamping strips 6, starts the conveying piece 3, moves the workpiece 4 between the two groups of heating assemblies 54, starts the hydraulic cylinder 51, drives the fixed frame plate 52 to move with the motor 53, drives the rotating shaft 541 to rotate with the guide roller 542, drives the ceramic heating body 543 to rotate with the heat-conducting shell 544, and the two heat-conducting shells 544 approach each other to flatten the outer wall of the non-woven fabric on both sides of the workpiece 4; during this process, the motor 53 is started, which drives the rotating shaft 541 and the guide roller 542 to rotate, and the guide roller 542 drives the ceramic heating body 543 and the heat-conducting shell 544 to rotate, which rolls and flattens the protruding non-woven fabric on the side wall of the workpiece 4, reduces the phenomenon of small particles on the outer wall of the non-woven fabric, and thus reduces the surface unevenness.

[0045] When the motor 53 drives the heating assembly 54 to rotate and flatten, the rubber ball 547 in the heating assembly 54 will first contact the non-woven fabric of the workpiece 4, and the rubber ball 547 will drive the sliding frame rod 545 to move under the reaction force of the workpiece 4. The sliding frame rod 545 drives the rotating plate 551 to deflect, and the rotating plate 551 drives the sliding block 553 to slide along the inner wall of the strip-shaped groove 552. The sliding block 553 moves towards the sliding frame rod 545, and the sliding block 553 drives the connecting rod 554 and the connecting frame plate 555 to slide synchronously. The connecting frame plate 555 drives the rotating rod 556 and the silica gel roller 557 to move synchronously, so that the silica gel roller 557 can contact the non-woven fabric of the workpiece 4 in the conveying direction, improving the positioning accuracy of the workpiece 4 and enhancing the positioning and flattening effect of the device on the non-woven fabric. When the silica gel roller 557 moves, the silica gel roller 557 drives the rotating ring 558 and the scraping strip 559 to move. Because the rotating ring 558 rotates on the side wall of the silica gel roller 557, when the scraping knife wall of the scraping strip 559 contacts the non-woven fabric, the scraping strip 559 can scrape the dried non-woven fabric. This process can remove residual substances on the surface of the non-woven fabric, ensuring that the surface of the non-woven fabric is clean and free of impurities.

[0046] When the connecting frame plate 555 moves, the connecting frame plate 555 drives the square plate 561 and the horizontal rod 562 to move, and the horizontal rod 562 drives the strip-shaped plate 569 and the cleaning strip 564 to move. The two cleaning strips 564 move closer to each other, enhancing the adhesion effect of the cleaning strip 564 and the heat-conducting shell 544, effectively removing impurities, dust or other accumulated substances on the surface of the heat-conducting shell 544, ensuring the cleanliness and good heat-conducting performance of the heat-conducting shell 544, and facilitating the flattening work of the heat-conducting shell 544 on the outer wall of the non-woven fabric. At the same time, since the square plate 561 drives the square shell 566 to move towards the heat-conducting shell 544, the piston plate 565 connected by the horizontal rod 562 will slide on the inner wall of the square shell 566. The airflow in the square shell 566 will be extruded by the piston plate 565 and enter the inside of the strip-shaped shell 567. The airflow will be discharged outward through the air holes 568 of the strip-shaped shell 567. When the scraping strip 559 scrapes the impurities of the non-woven fabric, the impurities will adhere to the side wall of the scraping strip 559, and the discharged airflow can effectively carry away these impurities, further ensuring the cleanliness and efficient operation of the equipment. The scraping strip 559 facilitates the scraping and cleaning work of the subsequent non-woven fabric.
