[0014] (1) When the embossing equipment processes PVC decorative film, it is equipped with components such as positioning rails, shafts, second telescopic cylinders and conveying wheels at the front and rear ends of the right side of the processing box. The positioning rails in the above components can protect and limit the PVC film on both sides, so that the embossing equipment has a certain positioning mechanism for the PVC decorative film, so that the PVC decorative film moves along a certain trajectory, ensuring the processing effect of the PVC decorative film. Before the PVC decorative film enters, the dust on the surface of the PVC decorative film can be sucked into the dust collection box by the dust removal hood, dust suction pipe and dust collection box, so that the upper surface of the PVC decorative film is clean before entering the interior. When embossing is performed later, it is not easy for dust to be sucked into the surface of the PVC film and affect the quality of embossing.

[0015] (2) When processing PVC decorative film, PVC decorative film of different thicknesses will be processed. If it is necessary to emboss PVC decorative film of different thicknesses, the heating embossing roller can be pushed to move stably up and down inside the processing box by setting components such as the first telescopic cylinder, connecting block, guide groove and sliding rod, so as to change the distance between the heating embossing roller and the support roller, thereby facilitating the embossing processing of PVC decorative film of different thicknesses.

[0016] (3) By setting up components such as a fixed retaining ring, a fixed block, a rotating shaft and a retaining block, the surface of the heated embossing roller of the embossing equipment is prone to dust and other issues as the usage time increases, which affects the processing effect of PVC. At this time, the addition of the above components makes it easy to disassemble and maintain the heated embossing roller from the inside of the processing box, thus making the heated embossing roller easy to maintain and simple to operate.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides an embodiment: a multi-layer composite embossing device for PVC decorative film with a positioning mechanism, including a processing box 1. A mounting block 20 is provided at the top of the processing box 1, a servo motor 12 is installed at the rear end of the mounting block 20, a heating embossing roller 4 is installed inside the mounting block 20, a fixing frame 9 is fixed at the bottom of the processing box 1, and a support roller 10 is movably arranged inside the fixing frame 9. A mounting frame 6 is installed on the right side of the processing box 1, a negative pressure fan 7 is installed at the bottom of the mounting frame 6, and an electric heater 8 is installed at the bottom of the negative pressure fan 7. Support frames 17 are installed at both the front and rear ends of the left side of the processing box 1, a second telescopic cylinder 11 is installed at one end of each support frame 17, and a positioning device is installed at one end of each second telescopic cylinder 11. The bottom of the positioning track 2 is movably mounted with a conveyor wheel 19 via a shaft 3. One end of the positioning track 2 is equipped with a guide rod 18. A dust collection box 28 is installed on the right side of the top of the processing box 1. A dust collection screen 29 is installed inside the dust collection box 28. A suction pipe 27 is installed at the top of the dust collection box 28, and a dust removal hood 26 is installed at the bottom of the suction pipe 27. A dust collection fan 30 is installed at the bottom of the dust collection box 28. The positioning track 2 is provided in two sets. The two sets of positioning tracks 2 form a telescopic structure through a second telescopic cylinder 11. The cross-section of the guide rod 18 is smaller than the cross-section of the support frame 17. A sliding structure is formed between the guide rod 18 and the support frame 17. The design of the sliding structure allows the second telescopic cylinder 11 to push the positioning track 2 to move back and forth stably.

[0025] Specifically, if Figure 1 Diagram and Figure 3 As shown, the second telescopic cylinder 11 is activated to push the positioning track 2 forward or backward, adjusting the distance between the two sets of positioning tracks 2 to a suitable size. This positions and guides the PVC film as it moves to the right, allowing it to move along a certain trajectory. Before the PVC film enters the processing chamber 1, the dust extraction fan 30 is activated to suck the dust from the bottom surface of the PVC film into the dust collection mesh 29 inside the dust collection chamber 28 through the dust extraction pipe 27 and dust hood 26, ensuring the upper surface of the PVC film is clean before it enters the processing chamber 1.

[0026] A mounting base 13 is installed at the top of the inside of the processing box 1, and a first telescopic cylinder 5 is installed at the bottom of the mounting base 13. A connecting block 14 is installed at the bottom of the first telescopic cylinder 5, and a sliding rod 16 is installed at the bottom of the connecting block 14. A guide groove 15 is provided on one side of the sliding rod 16, and the guide groove 15 is located at the front and rear ends inside the processing box 1. The cross-section of the sliding rod 16 is smaller than the cross-section of the guide groove 15. The sliding rod 16 and the guide groove 15 form a sliding structure. The design of the sliding structure allows the first telescopic cylinder 5 to push the heated embossing roller 4 to move up and down stably.

[0027] Specifically, if Figure 2 As shown, when the thickness of the processed PVC film is different, the height of the heating embossing roller 4, that is, the distance between the heating embossing roller 4 and the support roller 10, can be adjusted according to actual needs. When adjusting, the first telescopic cylinder 5 is activated and the sliding rod 16 slides inside the guide groove 15 to push the heating embossing roller 4 to move upward or downward stably, so that the distance between the heating embossing roller 4 and the support roller 10 is adjusted to a suitable size for use.

[0028] Assembly blocks 22 are fixed on both sides of the heated embossing roller 4. Mounting blocks 20 are provided on one side of each assembly block 22. Mounting blocks 20 are movably connected to the first telescopic cylinder 5. Fixing blocks 23 are fixed on the outer side wall of the assembly block 22. Fixing rings 21 are hinged to the outer side wall of each fixing block 23 via a rotating shaft 24. Locking blocks 25 are movably provided inside each fixing ring 21. One end of each locking block 25 is fixed to the outer side wall of the mounting block 20. The cross-section of the fixing ring 21 is larger than the cross-section of the locking block 25. The fixing ring 21 and the locking block 25 form a locking structure. There are four sets of fixing rings 21. The four sets of fixing rings 21 are arranged in a ring on the outer side wall of the assembly block 22. The design of the locking structure and the ring distribution design make the heated embossing roller 4 and the mounting block 20 stably installed together.

[0029] Specifically, if Figure 2 and Figure 4As shown, when disassembling and maintaining the heated embossing roller 4, open the door at the front of the processing box 1, flip the fixing ring 21 in sequence to disengage it from the outer wall of the locking block 25, and then pull the heated embossing roller 4 downward to separate the assembly blocks 22 on both sides from the mounting blocks 20. After cleaning and maintaining the heated embossing roller 4, align and attach the assembly blocks 22 and mounting blocks 20 on both sides of the heated embossing roller 4, and rotate the fixing ring 21 to engage with the corresponding locking block 25. The heated embossing roller 4 can then be reinstalled for continued use.

[0030] Working principle: In use, the multi-layer PVC film coated with adhesive is dusted off by the dust removal cover 26 and enters the processing box 1 from the left side. During the conveying of the PVC film, the positioning track 2 protects the two sides of the PVC film and positions it, allowing the PVC film to enter between the heating embossing roller 4 and the support roller 10 according to a certain trajectory. The heating embossing roller 4 is heated, and the heating embossing roller 4 and the support roller 10 heat and squeeze the multi-layer PVC film. At the same time, the printed pattern on the surface of the heating embossing roller 4 is also printed on the surface of the PVC decorative film. The PVC decorative film with the hot-pressed pattern moves to the right. The negative pressure fan 7 is turned on and blows air to the electric heater 8, so that the hot air blows downward onto the PVC decorative film pressed together, promoting the drying of the embossed pattern on its surface, and then the processing box 1 moves out to the right.
