[0021] The present invention will be described in detail below with reference to the accompanying drawings.

[0022] A PVC film material gluing device, such as Figure 1-Figure 2 As shown, it includes a box body 1, and a feed port 2 and a discharge port 3 are respectively provided on both sides of the box body 1. A transmission roller group 4 for transmitting film materials is provided in the box body 1, and a gluing roller 5 and a gluing roller 6 are rotatably connected to it are provided in the box body 1. The gluing roller 6 and the gluing roller 5 are in contact with each other. A moving block 7 is provided above the gluing roller 5, and a plurality of gluing heads 8 distributed in an array are provided on the moving block 7. The gluing heads 8 are each provided with a hose 9 connected to it at one end. The upper end face of the box body 1 is provided with a through groove 10 for the other end of the hose 9 to extend. Different glues are stored in their own independent storage boxes. One end of the hose 9 extending out of the through groove 10 is connected to the corresponding storage box. A valve is installed on the gluing head 8, and a driving device for driving the moving block 7 to move is provided on the inner wall of the box body 1.

[0023] The driving device includes a groove 11 arranged on the inner wall of the box body 1, and a screw rod 12 rotatably connected to the inner wall of the groove 11 is provided. A nut seat is provided on the screw rod 12, and the nut seat is integrally formed with the moving block 7. A cavity is provided on the inner wall of the box body 1, and a motor 13 for driving the screw rod 12 to rotate is installed in the cavity. The motor 13 is a servo motor, and the output shaft of the motor 13 is transmission-connected to one end of the screw rod 12.

[0024] A limiting block 14 is fixedly connected to the side wall of the moving block 7 away from the nut seat. The inner wall of the box body 1 is provided with a limiting groove for the limiting block 14 to be inserted and moved. When the nut seat and the moving block 7 move with the rotation of the screw rod 12, the limiting block 14 will be inserted into the limiting groove and move, making the moving block 7 more stable during the movement.

[0025] A mounting block 15 is fixedly connected to the inner wall of the box body 1, and a scraper 16 is rotatably connected to the side wall of the mounting block 15. A rotating mechanism for driving the scraper 16 to rotate is provided on the inner wall of the box body 1. The rotating mechanism includes a gear 17 rotatably connected to the mounting block 15, and the scraper 16 is fixedly connected to the gear 17. An electric cylinder 18 is fixedly connected to the inner wall of the box body 1, and the output end of the electric cylinder 18 is fixedly connected to a rack 19 meshing with the gear 17.

[0026] A collecting trough 20 is provided below the scraper 16 , and the collecting trough 20 is fixedly connected to the inner wall of the box body 1 . A guide groove 21 is provided on the upper end surface of the scraper 16 .

[0027] Working principle: When the PVC film material passes through the box body 1 through the transmission roller group 4, the glue output by the glue roller 5 will first be coated on the surface of the glue roller 5, and the glue roller 5 will then be evenly coated on the surface of the glue coating roller 6 through rotation. The glue coating roller 6 then coats the glue on the surface of the film material to complete the gluing process. When different types of glue need to be coated on the glue roller 5, the motor 13 can be used to drive the screw rod 12 to rotate. During the forward and reverse rotation of the screw rod 12, the nut seat will reciprocate along the screw rod 12, and the nut seat can drive the moving block 7 to move left and right, so that the different glue heads 8 on the moving block 7 come above the glue roller 5, and then open the valve on the corresponding glue head 8 to realize glue discharging and coating. When it moves to the appropriate position, the motor 13 is turned off and the rotation of the screw rod 12 is stopped. In this way, different discharging heads can be replaced to quickly change the type of glue, and each hose 9 and glue discharging head are independent, which can reduce the occurrence of mixing between various glues and improve the efficiency and quality of gluing.

[0028] At the same time, after the PVC film is coated with glue, it will be discharged from the discharge port 3 through the transmission of the transmission roller group 4. The scraper 16 will scrape off the excess glue on the surface of the PVC film, so that the glue coating on the surface of the PVC film is more uniform. According to the gluing requirements of different PVC film materials, the scraper 16 can be driven to rotate by the rotating mechanism to change the distance between the end of the scraper 16 and the film material. The rack 19 is driven to move by the telescopic electric cylinder 18. The movement of the rack 19 can drive the gear 17 to rotate. After the gear 17 rotates, it can drive the scraper 16 to rotate, so that the scraper 16 can scrape off glue of different thicknesses. The excess glue scraped off can be gathered in the collection tank 20 along the slope and guide groove 21 on the surface of the scraper 16, which is convenient for recycling the glue.

[0029] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
