All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] Embodiment 1

[0023] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a dry laminating device for PVC decorative films, including a machine body 1. Two mounting boxes 5 are slidably connected to the front end of the machine body 1. The two mounting boxes 5 are symmetrically designed up and down, and the machine body 1 plays a limiting role on the mounting boxes 5, so that the mounting boxes 5 can slide smoothly. A connecting rod 13 is slidably connected to the lower side inside the mounting box 5. The mounting box 5 plays a limiting role on the connecting rod 13, so that the connecting rod 13 can slide smoothly. An installation frame 8 is arranged outside the connecting rod 13. A flattening roller 9 is rotatably connected inside the installation frame 8. The installation frame 8 provides an installation space for the flattening roller 9. A protective ring 17 is sleeved outside the flattening roller 9. The protective ring 17 is in direct contact with the PVC decorative film and can be replaced, so that the PVC decorative film can be flattened smoothly and stably.

[0024] During use, by moving the two mounting boxes 5 towards the adjacent side, the mounting boxes 5 can drive the flattening roller 9 to fit with the upper and lower sides of the PVC decorative film. Then, when the PVC decorative film is wound up, it can be flattened by the flattening roller 9. This not only makes the adhesive coating inside it evenly distributed, but also makes the surface of the film free from wrinkles or abrasions, so that the quality of the production and processing of the PVC decorative film is relatively high.

[0025] Embodiment 2

[0026] On the basis of the first embodiment, in order to realize the convenient up-and-down movement of the mounting box 5, two support blocks 2 are fixedly connected to the left and right sides of the front end of the machine body 1. A bidirectional lead screw 3 is rotatably connected inside the two support blocks 2 on the right side. The support block 2 on the right side limits the internal bidirectional lead screw 3, so that the bidirectional lead screw 3 can rotate smoothly. Two nuts 4 are threadedly connected to the outside of the bidirectional lead screw 3. The left end of the nut 4 is fixedly connected to the right side of the mounting box 5. A guide rod 7 is fixedly connected to the inner sides of the two support blocks 2 on the left side. Two sliding sleeves 6 are slidably connected to the outside of the guide rod 7. The guide rod 7 limits the internal sliding sleeve 6, so that the sliding sleeve 6 can slide smoothly. The right side of the sliding sleeve 6 is fixedly connected to the left side of the mounting box 5. By using the sliding sleeve 6 and the guide rod 7 in cooperation, the mounting box 5 can move up and down stably.

[0027] When it is necessary to move the mounting box 5 up and down, by rotating the bidirectional lead screw 3, the bidirectional lead screw 3 can drive the two nuts 4 to move towards the adjacent side, and then the nut 4 can drive the mounting box 5 at the corresponding position to move towards the adjacent side. At this time, the mounting box 5 can drive the sliding sleeve 6 to move, and then the sliding sleeve 6 can slide on the outside of the guide rod 7, so that the mounting box 5 can slide more smoothly.

[0028] Embodiment Three

[0029] On the basis of the second embodiment, in order to achieve a better flattening effect of the flattening roller 9, a placement groove 10 is opened inside the mounting box 5. A rubber block 11 is fixedly connected to the upper side of the inner wall of the placement groove 10. A push plate 12 is fixedly connected to the bottom end of the rubber block 11. The push plate 12 is slidably connected inside the placement groove 10. The placement groove 10 limits the push plate 12, so that the push plate 12 can slide smoothly. A connecting rod 13 is fixedly connected to the upper side of the push plate 12. Multiple connecting rods 13 are equidistantly distributed, so that the force on the push plate 12 is more uniform.

[0030] After the flattening roller 9 contacts the PVC decorative film, the flattening roller 9 can push the connecting rod 13 to move outward through the mounting frame 8, and then the connecting rod 13 can squeeze the placement groove 10 through the push plate 12 to deform. Then when the placement groove 10 makes a reset movement, the placement groove 10 can push the push plate 12 to move inward, and then the push plate 12 can push the mounting frame 8 to move inward through the connecting rod 13, so that the mounting frame 8 can push the flattening roller 9 to closely fit the PVC decorative film.

[0031] Embodiment Four

[0032] On the basis of Embodiment 3, in order to replace the flattening roller 9, a clamping groove 15 is formed in the upper side inside the mounting frame 8. The connecting rod 13 is engaged with the inside of the clamping groove 15. A plurality of sealing grooves 16 are formed in the inside of the clamping groove 15. A plurality of sealing rings 14 are fixedly connected to the outside of the connecting rod 13. The outer side of the sealing ring 14 is designed in a conical shape, so that the sealing ring 14 can conveniently enter the inside of the clamping groove 15. The sealing ring 14 is matched with the sealing groove 16, and the sealing ring 14 is attached to the inside of the sealing groove 16, thereby increasing the friction between the connecting rod 13 and the clamping groove 15, and further making the installation of the mounting frame 8 relatively stable.

[0033] When disassembling the flattening roller 9, by pulling the mounting frame 8 in a direction away from the connecting rod 13, the sealing ring 14 can be disengaged from the inside of the sealing groove 16, so that the connecting rod 13 can be disengaged from the inside of the clamping groove 15, and then the mounting frame 8 can be conveniently disassembled, and the flattening roller 9 can be conveniently disassembled. When installing the flattening roller 9, by engaging the connecting rod 13 with the clamping groove 15, during this process, the sealing ring 14 enters the inside of the clamping groove 15 and slides inside it, so that the clamping groove 15 can squeeze the sealing ring 14 to deform. When the sealing ring 14 makes a reset movement, the sealing ring 14 can be attached to the inside of the sealing groove 16, and then the friction between the connecting rod 13 and the clamping groove 15 is relatively large, thereby making the installation of the mounting frame 8 relatively stable.

[0034] In actual use, first, the connecting rod 13 is engaged with the card slot 15. During this process, the sealing ring 14 enters the inside of the card slot 15 and slides inside it, so that the card slot 15 can squeeze the sealing ring 14 to deform. When the sealing ring 14 makes a reset movement, the sealing ring 14 can fit with the inside of the sealing groove 16, so that the frictional force between the connecting rod 13 and the card slot 15 is relatively large, making the installation of the mounting bracket 8 relatively stable. Then, by rotating the bidirectional lead screw 3, the bidirectional lead screw 3 can drive the two nuts 4 to move towards the adjacent side, so that the nut 4 can drive the mounting box 5 at the corresponding position to move towards the adjacent side. At this time, the mounting box 5 can drive the sliding sleeve 6 to move, so that the sliding sleeve 6 can slide on the outside of the guide rod 7, making the mounting box 5 slide more smoothly, so that the mounting box 5 can drive the flattening roller 9 to fit with the upper and lower sides of the PVC decorative film. When the PVC decorative film is wound up, it can be flattened by the flattening roller 9. After the flattening roller 9 contacts the PVC decorative film, the flattening roller 9 can push the connecting rod 13 to move outward through the mounting bracket 8, so that the connecting rod 13 can squeeze the placement groove 10 to deform through the push plate 12. When the placement groove 10 makes a reset movement, the placement groove 10 can push the push plate 12 to move inward, so that the push plate 12 can push the mounting bracket 8 to move inward through the connecting rod 13, making the mounting bracket 8 push the flattening roller 9 to closely fit with the PVC decorative film, not only making the adhesive coating inside it evenly distributed, but also preventing wrinkles or abrasions on the film surface, and improving the quality of the production and processing of the PVC decorative film.
