Description

Technical Field

[0001] This utility model relates to the field of PVC decorative paper hot pressing technology, and in particular to a PVC surface decorative paper hot pressing device. Background Technology

[0002] In the processing of PVC products, hot-pressing the decorative paper onto the PVC surface is a crucial step. Traditional hot-pressing equipment has many shortcomings. For example, uneven hot pressing often leads to air bubbles, voids, or poor adhesion between the decorative paper and the PVC board. This not only affects the appearance quality of the product but also reduces its durability.

[0003] When in use, the existing device requires workers to manually place and position the board and the decorative paper on top. Moreover, the temperature is high after hot pressing, and workers need to wait for a period of time for cooling before the board can be moved and a new board can be placed, which makes the work efficiency low. Therefore, we propose a PVC surface decorative paper hot pressing device. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-5 A PVC surface decorative paper hot pressing device includes a fixed frame 1, with extension frames 2 fixedly installed on the left and right sides of the fixed frame 1. A sheet conveyor belt 3 is rotatably installed between the inner walls of the front and rear sides of the extension frames 2. A first electric telescopic rod 4 is fixedly installed on the top of the fixed frame 1. The output end of the first electric telescopic rod 4 is fixedly installed with the main body 5 of the hot pressing device. A movable box 6 is provided on the top of the fixed frame 1. A limit frame 7 is fixedly installed on the bottom of the movable box 6. The limit frame 7 is slidably installed on the inner side of the fixed frame 1 and the extension frames 2. A sheet clamping box 8 is fixedly installed on one side of the movable box 6. Racks 9 are fixedly installed on the front and rear sides of the top of the fixed frame 1 and the extension frames 2. A first motor 10 is fixedly installed on one side of the movable box 6. A worm gear 11 is fixedly installed on the output end of the first motor 10. Multiple movable shafts 12 are rotatably installed on the inner side of the movable box 6. Worm wheels 13 are fixedly installed on the outer side of the movable shafts 12. The worm wheels 13 and the worm gears 11 mesh with each other. A transmission gear 14 is fixedly installed on the outer side of the movable shafts 12. The transmission gear 14 meshes with the adjacent rack 9.

[0024] A second motor 15 is fixedly installed on one side of the plate clamping box 8. A bidirectional lead screw 16 is fixedly installed at the output end of the second motor 15. Moving sliders 17 are threaded on the left and right sides of the outer side of the bidirectional lead screw 16. A second electric telescopic rod 18 is fixedly installed on one side of the moving slider 17. A clamping block 19 is fixedly installed on one side of the second electric telescopic rod 18. The clamping block 19 is L-shaped and has an anti-slip pad on one side. The anti-slip pad makes it easier for the clamping block 19 to clamp the plate with greater friction, resulting in a better clamping effect. A guide groove is opened on one side of the plate clamping box 8. The moving slider 17 is slidably installed inside the guide groove. The guide groove facilitates the guidance of the moving slider 17, allowing it to slide after being subjected to force. This allows the device to clamp plates of different sizes.

[0025] The top of the fixed frame 1 and the extension frame 2 are provided with a placement groove, and the rack 9 is fixedly installed on the inner side of the placement groove. The placement groove facilitates the placement of the rack 9, so that the rack 9 is at the same height as the fixed frame 1 and the extension frame 2, making it less likely to cause interference during the movement of the movable box 6. The bottom of the movable box 6 is provided with a through groove, and the transmission gear 14 rotates on the inner side of the through groove. The through groove facilitates the engagement of the transmission gear 14 with the rack 9 below after rotation, so that the movable box 6 can be moved under force after the transmission gear 14 rotates.

[0026] The implementation principle of this utility model is as follows: The device can place the board and decorative paper above the board conveyor belt 3 on one side. The first motor 10 drives the worm gear 11 to rotate, which in turn drives the movable shaft 12 to rotate via the worm wheel 13. The movable shaft 12, after rotating, drives the transmission gear 14 to rotate, allowing the transmission gear 14 to mesh with the rack 9. The rack 9 is fixed, so the transmission gear 14, after rotating, can drive the movable box 6 to bear force. The limiting frame 7 can limit the movable box 6, allowing it to move after bearing force. This allows the device to move the board clamping box 8 and the clamping block 19 to one side of the board for clamping. The sheet metal is moved to the bottom of the hot pressing device body 5 for hot pressing. During the movement of the clamping block 19, it can be retracted by the second electric telescopic rod 18, so that the clamping block 19 is less likely to collide with the sheet metal during the movement. According to the size of the sheet metal, the second motor 15 can be controlled to drive the bidirectional lead screw 16 to rotate, so that the bidirectional lead screw 16 can drive the moving slider 17 to move through the thread engagement. The moving slider 17 can drive the second electric telescopic rod 18 and the clamping block 19 to move their positions, so that the second electric telescopic rod 18 drives the clamping block 19 to clamp the sheet metal, making the clamping of the sheet metal more stable and less prone to interference.
