[0002] At present, there are many types of existing laminating machines, and the laminating action of the product is generally completed by pressing two smooth rollers together. However, during the laminating process, the film may deviate from the direction due to uneven pulling force, which will cause the film attached to the surface of the product to wrinkle, affecting the laminating effect of the product. In addition, the existing laminating machine has not undergone a high-temperature hot pressing process, and its laminating effect is poor and it is easy to fall off.

[0003] In the prior art, a Chinese patent has disclosed an improved high-temperature hot-pressing laminating machine (authorization announcement number: CN110949741A). After high-temperature hot pressing, the application document causes the PVC film skin and the substrate to undergo a physical and chemical reaction under the action of high temperature, so that they are fused together, and then cooperates with subsequent traction rollers to apply a protective film, thereby achieving the purpose of integrated production, cost savings, and reduced energy consumption; however, the hot pressing device in the above document fuses the PVC film skin and the substrate through a hot pressing roller, wherein the hot pressing roller, when performing hot pressing treatment on some substrates, has an uneven surface on some substrates themselves, which causes the substrate to be stuck between the two sets of hot pressing rollers when moving, making it impossible for the substrate to move between the two sets of hot pressing rollers.

[0004] Therefore, a high temperature hot pressing device for a laminating machine is provided to solve the problems raised in the above background technology. Summary of the invention

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0021] See also Figures 1 to 4 A high-temperature hot pressing device for a laminating machine comprises a laminating machine body 1, on which a hot pressing structure 2 is arranged, the hot pressing structure 2 comprises a symmetrical mounting seat 201, the mounting seat 201 is fixedly connected to the laminating machine body 1, a symmetrical driving groove 202 is provided on the mounting seat 201, a first buffer seat 203 and a second buffer seat 204 are respectively slidably connected inside the driving groove 202, a buffer groove 205 is provided on one side adjacent to the first buffer seat 203 and the second buffer seat 204, a sliding rod 206 is fixedly connected inside the buffer groove 205, a slider 208 is slidably connected to the sliding rod 206, a spring 207 is arranged between the sliders 208, the spring 207 is sleeved on the sliding rod 206, two groups of hinged rods 212 are hingedly arranged between the sliders 208, a mounting plate 209 is fixedly connected to the lower side of the second buffer seat 204, and a hot pressing roller 3 is rotatably connected to the mounting plate 209.

[0022] Among them, the coated substrate is placed on the laminating machine body 1, and then the substrate is pushed so that the substrate is inserted between the two groups of hot pressing rollers 3 until it extends between the pressing roller 404 and the roller wheel 402. The hot pressing roller 3 will perform hot pressing treatment on the substrate and the PVC film on the substrate when working, so that the PVC film and the substrate are fused. When the substrate expands in volume due to hot pressing, the substrate will apply pressure to the two groups of second buffer seats 204, and the second buffer seats 204 will transfer the pressure to the two groups of hinged rods 212, so that the two groups of hinged rods 212 will produce shear deformation, thereby offsetting the pressure applied by the substrate to the two groups of second buffer seats 204, so that the substrate can move between the two groups of hot pressing rollers 3 when the volume expands.

[0023] Preferably, Figure 2 As shown, the hinge rods 212 are arranged in an "X" shape, and the two sets of hinge rods 212 are movably connected via a rotating shaft.

[0024] When the two sets of hinged rods 212 are arranged in an "X" shape, when the hot pressing roller 3 is subjected to pressure, the two sets of hinged rods 212 will be shear-deformed, thereby moving the hot pressing roller 3 and preventing the substrate from being stuck between the two sets of hot pressing rollers 3.

[0025] Preferably, Figure 3 As shown, two groups of threaded rods 211 are spirally connected to the mounting seat 201 , and the threaded rods 211 are rotatably connected to the first buffer seat 203 .

[0026] The distance between the two groups of first buffer seats 203 can be adjusted by the threaded rod 211 , and the distance between the two groups of hot pressing rollers 3 can be adjusted according to the thickness of the substrate.

[0027] Preferably, Figure 1 As shown, a symmetrical fixing plate 4 and a symmetrical fixing seat 401 are fixedly connected to one side of the mounting seat 201, and a roller 402 is rotatably connected between the fixing seats 401. A driving motor 403 is installed on one side of the fixing seat 401, and the driving motor 403 drives the roller 402 to rotate. A pressing roller 404 is arranged on the upper side of the roller 402.

[0028] The substrate is disposed between the pressing roller 404 and the roller 402 after passing through the two sets of hot pressing rollers 3, so that the pressing roller 404 presses the substrate on the roller 402, so that when the roller 402 rotates, the substrate can be driven to move.

[0029] Preferably, Figure 1 As shown, a screw rod 406 is rotatably connected to the fixed plate 4 , one end of the screw rod 406 is rotatably connected to the fixed seat 401 , a sliding block 405 is spirally connected to the screw rod 406 , and a pressing roller 404 is rotatably connected between the sliding blocks 405 .

[0030] The position of the sliding block 405 can be changed by rotating the spiral rod 406 , thereby changing the distance between the pressing roller 404 and the roller 402 . Controlling the distance between the pressing roller 404 and the roller 402 can allow the substrate to move smoothly on the roller 402 .

[0031] Preferably, Figure 4 As shown, a symmetrical limit seat 5 is installed on the laminating machine body 1, a limit plate 502 is slidably connected to the limit seat 5, a ball is installed on the adjacent side of the limit plate 502, a limit rod 501 is spirally connected to the limit seat 5, and the limit rod 501 and the limit plate 502 are matching components.

[0032] The limiting plate 502 limits the substrate on the laminating machine body 1 to prevent the substrate from being offset during movement.

[0033] Working principle: by placing the coated substrate on the laminating machine body 1, and then pushing the substrate so that the substrate is inserted between the two groups of hot pressing rollers 3 until it extends between the pressing roller 404 and the roller wheel 402, wherein the hot pressing roller 3 will perform hot pressing treatment on the substrate and the PVC film on the substrate during operation, so that the PVC film and the substrate are fused, when the concave and convex surface of the substrate is in contact with the hot pressing roller 3, the convex surface of the substrate will exert pressure on the two groups of second buffer seats 204, and the second buffer seats 204 will transfer the pressure to the two groups of hinged rods 212, so that the two groups of hinged rods 212 will produce shear deformation, and the slider 208 will move on the slide rod 206, so that the second buffer seat 204 will move up, thereby offsetting the pressure exerted by the substrate on the two groups of second buffer seats 204, so that the uneven substrate can move between the two groups of hot pressing rollers 3.
