Using the existing pulse heat sealing technology, the metal pressure head is heated by electric current in a short time to achieve rapid film welding. After adjusting the distance between the two heating rollers 11, the first film clamp 501 of different diameters can be replaced, so that the first film clamp 501 can always clamp the film even when there is no product coating.

[0028] See the instructions attached Figure 5 and Figure 7 As shown, the second clamping roller structure 13 includes two parallel second end blocks 1302, with a second film clamping rod 1301 detachably disposed between the two second end blocks 1302.

After adjusting the distance between the two heating rollers 11, the second film clamping rollers 1301 of different diameters can be replaced, so that the second film clamping rollers 1301 can always clamp the film when there is no product lamination.

[0029] See the instructions attached Figure 1 、 Figure 4 、 Figure 5 and Figure 9As shown, the clamping and rotating support structure 3 includes a first electric telescopic rod 301, which is fixed to the roller bracket 801 via a fixing base 302.

[0030] See the instructions attached Figure 3 and Figure 9 As shown, the gear rotation support structure 4 includes a vertical beam 401, which is fixedly mounted on the push rod of the first electric telescopic rod 301.

The film feed roller 2 is provided with a second gear 404 that meshes with the first gear 403. A crossbeam 405 is fixedly mounted on the lower end of the vertical beam 401. The two ends of the crossbeam 405 are rotatably connected to support wheels 406 for supporting the film feed roller 2. Through the above-mentioned specific structural design, the rotation of the output shaft of the first motor 402 can drive the rotation of the first gear 403, and the rotation of the first gear 403 can drive the meshing second gear 404 to rotate, thereby driving the film feed roller 2 to rotate under the support of the support wheels 406, thereby feeding the film. It can also cooperate with the tension adjustment detection structure 7 to adjust the tension of the film. The output end of the digital display control panel 10 is electrically connected to the input end of the first motor 402.

[0031] See the instructions attached Figure 3 、 Figure 4 and Figure 5 As shown, the gear linkage drive structure 9 includes a fourth gear 904 disposed at the ends of the first clamping roller structure 5 and the second clamping roller structure 13, respectively, and a second gear 902 disposed at the end of the heating roller 11. A third gear 903 is meshed and connected between the second gear 902 and the fourth gear 904. The other end of the heating roller 11 is provided with a second motor 901 for driving its rotation. In actual application, the gear linkage drive structure 9 can achieve linkage between the first clamping roller structure 5, the heating roller 11, and the second clamping roller structure 13. The gear speed ratio can be adjusted by using second gears 902, third gears 903, and fourth gears 904 of different diameters, thereby ensuring that the outer edges of the first clamping roller structure 5, the heating roller 11, and the second clamping roller structure 13 have the same linear speed, thereby achieving synchronous transmission of the film. The output end of the digital display control panel 10 is electrically connected to the input end of the second motor 901.

[0032] See the instructions attached Figure 3 and Figure 10 As shown, the elastic clamping adjustment structure 6 includes an arc-shaped guide hole 601 provided on the roller bracket 801, a guide slider 602 is slidably provided in the arc-shaped guide hole 601, and the shaft end of the clamping roller structure is connected to a first rotating shaft 606, the first rotating shaft 606 is rotatably connected to the guide slider 602 through a bearing and is fixedly connected to the shaft end of the fourth gear 904, a rotating rod 605 is rotatably provided on the first rotating shaft 606, one end of the rotating rod 605 is rotatably connected to the roller bracket 801 through a second rotating shaft 607, and the rotation axis of the second rotating shaft 607 and the rotation axis of the third gear 903 are collinear with each other. The other end of the rotating rod 605 is rotatably connected to a rotating connecting block 609, and a second electric telescopic rod 610 is provided on one side of the rotating connecting block 609. The second electric telescopic rod 610 is hinged and rotated to the roller bracket 801 through a hinge shaft 611. The push rod head end of the second electric telescopic rod 610 slides through the through-hole provided at the corresponding position of the rotating connecting block 609 and is fixedly connected to the limiting sleeve 608. A blocking sleeve 603 is fixedly provided on the push rod of the second electric telescopic rod 610, and a spring 604 is nested on the outside of the push rod of the second electric telescopic rod 610 between the blocking sleeve 603 and the rotating connecting block 609. Through the above-mentioned specific structural design, the elastic clamping adjustment structure 6 can achieve adaptive adjustment of the spacing between the two first clamping roller structures 5 and the two second clamping roller structures 13. Specifically, when the product passes between the first clamping roller structure 5 and the two second clamping roller structures 13, the elastic deformation of the spring 604 and the sliding of the guide slider 602 within the arc-shaped guide hole 601 enable the first and second clamping roller structures 5 and 13 to elastically press the film and the product together. Furthermore, after the spacing is adjusted, the second electric telescopic rod 610 can also adjust the spacing between the two first clamping roller structures 5 and the two second clamping roller structures 13, accommodating the lamination of products of different sizes and thicknesses. Another function of the elastic clamping adjustment structure 6 is to clamp and secure the film between the rollers after lamination, preventing the film from falling off the rollers. The output of the digital display control panel 10 is electrically connected to the input of the second electric telescopic rod 610.

[0033] See the instructions attached Figure 2 、 Figure 3 and Figure 8As shown, the tension adjustment detection structure 7 includes a crossbar 701 fixedly disposed between the two side brackets 101. A third electric telescopic rod 702 is fixedly disposed on the crossbar 701. The push rod tip of the third electric telescopic rod 702 is connected to a wheel frame 704 via a pressure sensor 705. A tension adjustment roller 706 is rotatably disposed on the wheel frame 704. One end of the tension adjustment roller 706 is provided with a rotary encoder 707, which is mounted on the wheel frame 704. Two first guide rods 703 are symmetrically disposed on either side of the third electric telescopic rod 702. One end of each first guide rod 703 is fixedly connected to the wheel frame 704, and the other end of each first guide rod 703 slides through first guide holes defined in corresponding positions on the crossbar 701. The overall function of the tension adjustment detection structure 7 is to detect and dynamically adjust the tension of the film fed from the film feed roller 2 in real time, thereby ensuring that the film maintains appropriate tension during conveying and laminating, thereby guaranteeing the stability of the laminating quality. Specifically, the third electric telescopic rod 702 drives the dancer roller 706 to move horizontally, thereby varying its pressure on the film and adjusting the film's tension. A pressure sensor 705 senses the pressure between the dancer roller 706 and the film, reflecting the film's tension. The dancer roller 706 directly contacts the film, adjusting film tension by changing its position. A rotary encoder 707 detects the rotational speed of the dancer roller 706, indirectly reflecting the film's conveying speed and length. The two first guide rods 703 guide the movement of the wheel frame 704, ensuring smooth movement of the dancer roller 706 and preventing deviation from affecting adjustment accuracy. The output of the digital display control panel 10 is electrically connected to the input of the third electric telescopic rod 702. The outputs of the pressure sensor 705 and rotary encoder 707 are each electrically connected to the input of the digital display control panel 10.

[0034] A conveyor 12 is provided on one side between the two first clamping roller structures 5 and on one side between the two second clamping roller structures 13. The height of the upper transmission surface of the conveyor 12 is flush with the height of the upper side of the heating roller 11 located below. Through the above-mentioned specific structural design, the main function of the two conveyors 12 is to realize the transportation of the vehicle-borne components to be coated, so that they can smoothly enter between the upper and lower second clamping roller structures 13, and be guided out from between the upper and lower first clamping roller structures 5 after the coating is completed. The height of the upper transmission surface of the conveyor 12 is flush with the height of the upper side of the heating roller 11 located below, which can ensure that the vehicle-borne components to be coated maintain a smooth transition during the transmission process, avoid tilting or jamming of the components when entering the coating area of ​​the heating roller 11 due to height difference, and ensure that the components are always in a horizontal state during the coating process. In addition, after the height of the upper heating roller 11 is adjusted, it will not affect the use of the conveyor 12. The output end of the digital display control panel 10 is electrically connected to the input end of the conveyor 12. Working principle and technical effects of the present invention: During use, the vehicle-mounted components to be coated are transported by the conveyor 12 close to the side of the second clamping roller structure 13. Since the upper surface of the conveyor 12 is at the same height as the upper side of the heating roller 11 below, the components can smoothly enter between the upper and lower second clamping roller structures 13. After being heated by the heating roller 11 to complete the coating, they are transported and exported by the conveyor 12 on the side of the first clamping roller structure 5, thus completing the entire conveying process.

[0035] The film feeding roller 2 rotates to feed the film under the support of the clamping rotating support structure 3 and the drive of the gear rotating support structure 4. When the exported film passes through the tension adjustment detection structure 7, the tension adjustment roller 706 contacts the film, the rotary encoder 707 detects the film conveying speed, and the pressure sensor 705 senses the film pressure. The third electric telescopic rod 702 drives the tension adjustment roller 706 to move according to the detection results, and cooperates with the guidance of the first guide rod 703 to dynamically adjust the tightness of the film to ensure that the film tension is appropriate.

[0036] The gear linkage drive structure 9 drives the first clamping roller structure 5, the heating roller 11 and the second clamping roller structure 13 to rotate in conjunction. After the component enters with the conveyor, the second clamping roller structure 13 clamps the product and the film under the action of the elastic clamping adjustment structure 6 to ensure a firm fit. Under the heating and pressure of the upper and lower heating rollers 11, the film is bonded to both sides of the component; the upper and lower corresponding first clamping roller structures 5 clamp the film under the action of the elastic clamping adjustment structure 6, and the electric heating pressure ring 508 of the first film clamping roller 501 heats and presses the edge of the film; when the transmission of the product is stopped, the first clamping roller structure 5 and the second clamping roller structure 13 clamp the film under the action of the elastic clamping adjustment structure 6 to keep it elastically pressed and fixed.

[0037] The hydraulic cylinder 802 of the spacing adjustment assembly 8 drives the upper roller bracket 801 along the second guide rod 803.
