[0016] By adopting the above technical solution: The PC film is the film to be embossed, the PMMA film plays a strengthening role, and the PET film plays a protective role. When embossing, the PC film, PMMA film, and PET film are preheated via the preheating roller 10. If the PET film does not need to be preheated, it can bypass the preheating roller 10. Then, the PC film, PMMA film, and PET film pass between the rubber roller 9 and the microprism annular plate 13. The lifting block 7 drives the support roller 8 and the rubber roller 9 to move upward, enabling the PC film to be embossed through the microprism annular plate 13. After embossing, the PC film, PMMA film, and PET film are cooled by the first cooling roller 14 and the second cooling roller 39. Then, the film is wound on the upper winding table 15 and the lower winding table 16. If the outer side does not need protection, the PET film can be wound on the lower winding table 16, and the PC film and PMMA film can be wound on the upper winding table 15. If the outer side needs protection, the PC film, PMMA film, and PET film can be wound on the upper winding table 15. Through the above operations, continuous embossing of the film can be achieved, thereby improving the embossing efficiency.

[0017] As Figure 1 、 Figure 2 shown, a guiding roller 17 is arranged inside the unwinding frame 1; a first adjusting roller 18 is arranged on the hot pressing frame 2; a side pressing roller 19 is arranged below the first adjusting roller 18; the side pressing roller 19 is located inside the side block 20; the side pressing roller 19 is located on one side of the preheating roller 10; the side block 20 is connected to the first oil cylinder 21; the lifting block 7 is connected to the second oil cylinder 22.

[0018] By adopting the above technical solution: The guiding roller 17 guides the PC film, PMMA film, and PET film respectively to enter the hot pressing frame 2, and the first adjusting roller 18 adjusts the film to prevent the film from wrinkling; the first oil cylinder 21 can adjust the distance between the side block 20 and the preheating roller 10, thereby adjusting the distance between the side pressing roller 19 and the preheating roller 10 to facilitate adjusting the distance between the side pressing roller 19 and the preheating roller 10 according to the thickness of the film, so as to achieve a good preheating effect; the second oil cylinder 22 can control the position of the lifting block 7, thereby controlling the positions of the support roller 8 and the rubber roller 9, and can adjust the position of the lifting block 7 according to the thickness of the film, so as to better emboss the film.

[0019] As Figure 2 、 Figure 3 、 Figure 4 shown, a fixed block 23 and a moving block 24 are arranged on the hot pressing frame 2; one side of the moving roller 12 is located on the moving block 24; the moving block 24 is connected to the third oil cylinder 25; one side of the heating electromagnetic roller 11 is located on the fixed block 23; the other side of the moving roller 12 is arranged on the first limiting strip 26; the other side of the heating electromagnetic roller 11 is arranged on the second limiting strip 27.

[0020] By adopting the above technical solution: One end of the moving roller 12 penetrates through the moving block 24, and one end of the heating electromagnetic roller 11 penetrates through the fixed block 23. The upper ends of the first limiting strip 26 and the second limiting strip 27 are circular rings. The other side of the moving roller 12 is arranged on the circular ring on the first limiting strip 26, and the other side of the heating electromagnetic roller 11 is arranged on the circular ring on the second limiting strip 27. The moving block 24 is located on the guide rail on the hot pressing frame 2, and the third oil cylinder 25 enables the moving block 24 to move on the guide rail, and the fixed block 23 is fixedly connected to the hot pressing frame 2 so that the heating electromagnetic roller 11 is stably arranged.

[0021] When it is necessary to replace the micro prism annular plate 13, after the third oil cylinder 25 and the subsequent fourth oil cylinder 35 are started, the moving block 24 and the moving roller 12 move closer to the fixed block 23 and the heating electromagnetic roller 11. Then, the fixed block 23 and the moving block 24 are removed, and finally the micro prism annular plate 13 is replaced. After replacement, it is convenient to press different patterns on the film. When the fixed block 23 and the moving block 24 are removed, since the other sides of the heating electromagnetic roller 11 and the moving roller 12 are respectively located on the circular rings on the second limiting strip 27 and the circular rings on the first limiting strip 26, the heating electromagnetic roller 11 and the moving roller 12 can be prevented from falling off.

[0022] As Figure 3 、 Figure 4 shown, a first bottom block 28 is arranged below the first limiting strip 26; a second bottom block 29 is arranged below the second limiting strip 27; the second limiting strip 27 is threadedly connected to the second bottom block 29; there is a block groove 30 on the first bottom block 28; the first limiting strip 26 penetrates through the block groove 30; a limiting screw 31 is arranged on the first limiting strip 26; the limiting screw 31 is threadedly connected to the first limiting strip 26 and is located on both sides of the first bottom block 28.

[0023] As Figure 4 shown, there is a chute 32 on the hot pressing frame 2; there is a slider 33 on the chute 32; the other side of the moving roller 12 penetrates through the slider 33 and is located on the first limiting strip 26; the slider 33 is connected to a protruding block 34; the protruding block 34 is connected to the fourth oil cylinder 35.

[0024] By adopting the above technical solutions: The second limiting strip 27 and the second bottom block 29 are threadedly connected, so that the connection between the second limiting strip 27 and the second bottom block 29 is firm, and further the heating electromagnetic roller 11 is stably arranged; One end of the first limiting strip 26 penetrates through the block slot 30. When moving the moving block 24 and the moving roller 12, the third oil cylinder 25 and the fourth oil cylinder 35 are started to drive the moving block 24 and the slider 33 to move respectively. The slider 33 moves on the chute 32 and the moving block 24 moves on the guide rail. Their moving directions are the same, so that the moving roller 12 moves closer to the heating electromagnetic roller 11, which is convenient for removing the fixed block 23 and the moving block 24 to replace the micro prism annular plate 13; The protruding block 34 enables the fourth oil cylinder 35 to drive the slider 33 to move.

[0025] As Figure 1 shown, there is a fifth oil cylinder 36 on the hot pressing frame 2; The fifth oil cylinder 36 is connected to the rotating rod 37; One end of the rotating rod 37 is connected to the hot pressing frame 2 through the inserting rod 38; A first cooling roller 14 is arranged between the rotating rods 37; A second cooling roller 39 is arranged on one side of the first cooling roller 14.

[0026] By adopting the above technical solutions: The inserting rod 38 connects the rotating rod 37 and the hot pressing frame 2, so that the rotating rod 37 rotates around the inserting rod 38. When the telescopic shaft of the fifth oil cylinder 36 extends and retracts, it can drive the rotating rod 37 to rotate, so as to adjust the positions of the rotating rod 37 and the first cooling roller 14 according to the thickness of the embossed film, so as to better cool the film. After cooling on the first cooling roller 14, it is cooled again by the second cooling roller 39, so that the cooling effect is better.

[0027] As Figure 1 shown, a winding roller 40 is arranged on the winding frame 3; A second adjusting roller 41 is arranged between the winding rollers 40; A constant temperature lamp 42 is arranged on the unwinding frame 1; The constant temperature is connected to the sixth oil cylinder 43.

[0028] By adopting the above technical solutions: The winding roller 40 guides the film; The second adjusting roller 41 adjusts the film to prevent the film from wrinkling, so that the film can be stably wound on the upper winding table 15 and the lower winding table 16; If the embossed film does not need protection, the PET film can be wound on the lower winding table 16. If protection is needed, the PC film, PMMA film and PET film can be wound on the upper winding table 15 to complete the winding of the film; The constant temperature lamp 42 adjusts the distance from the film through the sixth oil cylinder 43, so as to keep the temperature of the film after preheating and prevent the temperature of the film from decreasing during embossing.

[0029] In summary, the present invention has the following beneficial effects: When embossing, the upper winding table 4 places the film roll to be embossed, i.e., the PC film roll, the middle winding table 5 places the PMMA film roll, and the lower winding table 6 places the PET film roll; when embossing, the PC film and the PMMA film are preheated via the preheating roller 10, and then enter between the rubber roller 9 and the microprism annular plate 13 for embossing. The pattern on the microprism annular plate 13 is printed onto the PC film, and then the film is cooled via the first cooling roller 14 and the second cooling roller 39 and finally wound onto the upper winding table 15 to complete the embossing. Through the above operations, continuous and rapid embossing can be achieved, thereby improving the embossing efficiency.

[0030] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention shall be included within the protection scope of the present invention.
