[0029] A first motor 308 is installed on the gantry frame 2. The rotating shaft 301 is fixedly connected to the output shaft of the first motor 308. When it is necessary to adjust the position of the guide wheel 307 according to the different widths of the plates, the first motor 308 is started. When the output shaft of the first motor 308 rotates, it drives the rotating shaft 301 to rotate. When the rotating shaft 301 rotates, it drives the gear 302 to rotate. When the gear 302 rotates, it drives the two racks 303 to move towards each other. When the racks 303 move towards each other, they drive the connecting rod 304 to move. The connecting rod 304 drives the mounting rod 305 to move. The two mounting rods 305 drive the mounting shaft 306 to move towards the guide wheel 307, thereby simultaneously adjusting the guide wheels 307 on the front and rear sides. Thus, through the cooperation of the gear 302 and the rack 303, it is convenient to quickly adjust the position of the guide wheels 307 on the front and rear sides of the laminating machine body 1, improving the adjustment efficiency of the guide wheels 307.

[0030] The pressing structure 4 includes connecting blocks 401 that are slidably connected to the fixed plate 9 and the guide frame 8 respectively. A connecting shaft 402 is rotatably connected between the two connecting blocks 401. A pressure roller 403 is fixedly connected to the connecting shaft 402.

A material trough 605 is fixedly connected to the fixing plate 9. A second hydraulic rod 604 is fixedly connected to the fixing plate 9. The slider 601 is fixedly connected to the telescopic end of the second hydraulic rod 604. First, remove the front retaining ring 502 from the feeding roller 501. Then, attach the PVC roll film to the feeding roller 501. Then, slide the front retaining ring 502 and the feeding roller 501 until they contact the PVC film roll. At this point, turn the knob 503 to press the knob 503 against the feeding roller 501 and fix the retaining ring 502. Then, pass the film roll between the two connecting rollers 603, then pass it through the drying chamber 12 from above the right guide roller 11, and pull it from above the left guide roller 11 to below the pressure roller 403, where it contacts the sheet. At this point, activate the second hydraulic rod 604. When the extension end of the second hydraulic rod 604 extends, it will drive the slider 601 to move downward. The slider 601 will drive the upper fixed shaft 602 and the connecting roller 603 to move downward, so that the upper connecting roller 603 is pressed against the PVC film. At the same time, activate the first hydraulic... The extension end of the first hydraulic rod 404 drives the connecting block 401 to move downward, causing the connecting block 401 to drive the pressure roller 403 to move downward through the connecting shaft 402, so that the PVC film is adhered to the board. Then, the laminating machine body 1 is started, and the laminating machine body 1 conveys the board. At the same time, the second motor 406 is started. When the output shaft of the second motor 406 rotates, it drives the connecting shaft 402 to rotate. When the connecting shaft 402 rotates, it drives the pressure roller 403 to rotate. When the pressure roller 403 rotates, it cooperates with the laminating machine body 1 to convey the board and adhere the PVC film to the board. At the same time, as the PVC film is continuously fed, it causes the two connecting rollers 603 to rotate. When the connecting rollers 603 rotate, they apply the adhesive in the material trough 605 to the PVC film.

Guide rollers 11 are rotatably connected to the guide shafts 10. A drying box 12 is installed on the fixed plate 9. When the glue in the material trough 605 needs to be added, the container containing the glue is placed in front of the laminating machine body 1, the first connecting pipe 703 is placed in the container, and the suction pump 702 is started. The suction pump 702 will suck the glue from the first connecting pipe 703 to the second connecting pipe 704, and then from the second connecting pipe 704 to the material trough 605 to complete the feeding, reducing the feeding difficulty.
