[0016] (1) By providing a glue storage tank, a glue coating roller, a sizing roller, a feeding port and a positioning shaft, when reprocessing, when the device exports the film from the outside of the film roller, the glue coating roller will adhere to the bottom of the film. The rotation of the glue coating roller drives the sizing roller at the bottom to rotate.

[0028] Specifically, as Figure 1 and Figure 3 shown, during reprocessing, when the device exports the film from the outside of the film material roller 2, the glue coating roller 5 will fit on the bottom of the film. The rotation of the glue coating roller 5 drives the bottom glue applying roller 21 to rotate. While the glue applying roller 21 rotates, the adhesive in the glue storage tank 4 is applied to the outside of the glue coating roller 5. Then the glue coating roller 5 evenly applies the adhesive on the bottom of the plastic film, ensuring uniform coating during continuous operation. And the adhesive can be added through the feeding port 22, realizing automatic and uniform application of the adhesive.
[0029] Embodiment 2: At the top of the frame 1, a fixing plate 13 is fixedly connected. At the top of the fixing plate 13, an electric cylinder 12 is fixedly connected. The output end of the electric cylinder 12 penetrates through the fixing plate 13 and is fixedly connected with a mounting frame 11. At both sides of both ends of the mounting frame 11, limiting grooves 24 are provided. At the top of both ends inside the frame 1, two groups of limiting plates 25 are respectively fixedly connected. Inside the mounting frame 11, a pressing roller 14 is movably connected. At the top inside the frame 1, a positioning roller 6 is movably connected;
[0030] The center line of the positioning roller 6 and the center line of the pressing roller 14 are in the same vertical plane, and the limiting grooves 24 are slidably connected with the limiting plates 25;
[0031] The pressing rollers 14 inside the mounting frame 11 are arranged at equal intervals, and the positioning rollers 6 inside the frame 1 are arranged at equal intervals;
[0032] Specifically, as Figure 1 and Figure 4As shown in the figure, during processing, the plastic film outside the film roller 2 and the printed matter outside the paper roller 3 are led out and bonded together and passed through between the positioning roller 6 and the pressing roller 14. Then, the electric cylinder 12 is started to drive the mounting frame 11 to descend. The mounting frame 11 then drives the pressing roller 14 inside it to descend. The pressing roller 14 cooperates with the positioning roller 6 to quickly press and bond the film. And the limiting plate 25 fits inside the limiting groove 24 to effectively limit the mounting frame 11, ensuring the stability of the pressing roller 14 during processing and lifting, and realizing automatic pressing of the film.
[0033] Embodiment 3: Fixed frames 20 are fixedly connected to the same side of both ends of the frame 1. A driving seat 18 is movably connected inside the fixed frame 20. The output end of the driving seat 18 is fixedly connected to a mounting disc 19. One end of the mounting disc 19 is fixedly connected to a hexagonal shaft 7. A winding drum 9 is arranged on one side inside the frame 1. A hexagonal hole 8 is arranged inside the winding drum 9. One end of the fixed frame 20 is fixedly connected to a cylinder 17. A tensioning roller 10 is movably connected to one side inside the frame 1;
[0034] The hexagonal hole 8 is movably connected to the hexagonal shaft 7. The center line of the winding drum 9 and the center line of the hexagonal hole 8 are on the same vertical plane;
[0035] The output end of the cylinder 17 extends into the fixed frame 20 and is fixedly connected to the driving seat 18. The mounting disc 19 is movably connected to the winding drum 9;
[0036] Specifically, as Figure 1 and Figure 2 shown, during processing, first wind the film around the outside of the tensioning roller 10 and then wind it around the outside of the winding drum 9. Then, start the driving seats 18 at both ends to drive the hexagonal shaft 7 to rotate through the mounting disc 19. The hexagonal shaft 7 then drives the winding drum 9 to rotate through the hexagonal hole 8 to automatically wind the film. After winding is completed, start the cylinders 17 at both ends to drive the driving seat 18 to move towards one end. The driving seat 18 drives the hexagonal shaft 7 to disengage from the inside of the hexagonal hole 8, and the winding drum 9 can be removed from inside the frame 1 to facilitate blanking, realizing automatic winding of the film and convenient blanking.
[0037] Working principle: When the utility model is in use and during reprocessing, when the device exports the film from the outside of the film roller 2, the glue coating roller 5 will adhere to the bottom of the film. The rotation of the glue coating roller 5 drives the rotation of the upper glue roller 21 at the bottom. While the upper glue roller 21 rotates, the adhesive glue inside the glue storage tank 4 is applied to the outside of the glue coating roller 5. The glue coating roller 5 then evenly applies the adhesive glue to the bottom of the plastic film to ensure uniform coating during continuous operation. And the adhesive can be added through the feeding port 22. During processing, the plastic film outside the film roller 2 and the printed matter outside the paper roller 3 are exported and adhered together and passed through between the positioning roller 6 and the pressing roller 14. Then, the electric cylinder 12 is started to drive the mounting frame 11 to descend. The mounting frame 11 then drives the pressing roller 14 inside it to descend. The pressing roller 14 cooperates with the positioning roller 6 to quickly press and adhere the film. And the limiting plate 25 fits inside the limiting groove 24 to effectively limit the mounting frame 11 and ensure the stability of the pressing roller 14 during processing and lifting. During processing, first, the film is wound around the outside of the tension roller 10 and then wound around the outside of the winding drum 9. Then, the driving seats 18 at both ends are started to drive the hexagonal shaft 7 to rotate through the mounting disc 19. The hexagonal shaft 7 then drives the winding drum 9 to rotate through the hexagonal hole 8 to automatically wind the film. After winding is completed, the cylinders 17 at both ends are started to drive the driving seat 18 to move towards one end. The driving seat 18 drives the hexagonal shaft 7 to disengage from the inside of the hexagonal hole 8, and the winding drum 9 can be removed from the inside of the machine frame 1 to facilitate material discharging.
