[0023] Embodiment

[0024] Please refer to Figures 1-5 , the present utility model provides a technical solution: a flattening device for plastic film processing, including a support frame 1, and a flattening assembly for flattening the plastic film is installed on the support frame 1.

[0025] By setting the flattening component, the wrinkled plastic film can be first smoothed and then flattened, improving the flattening effect of the plastic film. The flattening component includes a fixed block 4, two support plates 5 and two pressure rollers 6. An installation frame 3 is installed at the top of the support frame 1. The fixed block 4 is fixedly connected to one side of the installation frame 3. The two support plates 5 are fixedly connected to both sides of the top of the installation frame 3. The two pressure rollers 6 are respectively installed between the two sides of the fixed block 4 and the two support plates 5. One end of each of the two pressure rollers 6 is fixedly connected with a first bevel gear 7. Fixed frames 8 are installed on both sides of the support frame 1. A rotating shaft 9 is installed on the fixed frame 8. A second bevel gear 10 is installed at the top end of the rotating shaft 9. A worm gear 11 is installed at the bottom end of the rotating shaft 9. A driving component is installed between the two fixed frames 8. The worm gear 11 drives the second bevel gear 10 to rotate through the rotating shaft 9. The second bevel gear 10 drives the first bevel gear 7 at one end of the pressure roller 6 to rotate, thereby driving the two pressure rollers 6 to rotate in the same direction, so as to smooth the wrinkled plastic film to both sides. At the same time, when the plastic film passes between the pressure roller 6 and the driving roller 2, the plastic film can be flattened.

[0026] Using a driving motor 13 as the power source reduces the failure rate of the device and makes the device easy to maintain. A driving roller 2 is installed inside the support frame 1. The driving roller 2 is located below the two pressure rollers 6. The driving component includes a worm 12 and a driving motor 13. The worm 12 is rotatably connected between the two fixed frames 8. The driving motor 13 is installed on the outside of one fixed frame 8. The output shaft of the driving motor 13 is fixedly connected to one end of the worm 12 extending outside the fixed frame 8. The second bevel gear 10 is meshed and connected to the outside of the first bevel gear 7. The worm 12 is meshed with the outside of the worm gear 11. The output shaft of the driving motor 13 drives the worm 12 to rotate, and the worm 12 drives the worm gear 11 to rotate, so that the worm gear 11 drives the second bevel gear 10 to rotate through the rotating shaft 9.

[0027] A connecting frame 14 is installed on one side of the top of the support frame 1 where the installation frame 3 is located. A connecting roller 15 is installed inside the connecting frame 14. A tensioning roller 16 is installed on one side of the driving roller 2 inside the support frame 1. Adjusting components are arranged on both sides of the support frame 1. When the plastic film is flattened, it first passes between the driving roller 2 and the pressure roller 6, and then passes through the connecting roller 15 and is wound around the outside of the tensioning roller 16, so as to ensure the flatness of the plastic film. Both the driving roller 2 and the connecting roller 15 are driven by motors.

[0028] By setting the adjusting component, the flatness of the plastic film can be improved; the adjusting component includes a frame body 17, a slider 18 and a bolt 19. The frame body 17 is fixedly connected to both sides of the support frame 1. Through grooves are formed on the inner sides of both sides of the support frame 1 within the frame body 17. The slider 18 is slidably connected to the inside of the frame body 17 and is movably connected to the connecting shafts at both ends of the tension roller 16. The bolt 19 is threadedly connected to one end of the frame body 17, and one end of the bolt 19 is rotatably connected to one side of the slider 18. By rotating the bolt 19, the slider 18 is driven to move inside the frame body 17, thereby driving the tension roller 16 to be adjusted forward and backward, so as to adjust the tension degree of the plastic film winding and ensure the flatness of the plastic film winding.

[0029] Regarding the working principle or structural principle, when the wrinkled plastic film needs to be wound, the driving motor 13 is controlled to start through the switch group. The output shaft of the driving motor 13 drives the worm 12 to rotate, and the worm 12 drives the worm wheel 11 to rotate, so that the worm wheel 11 drives the second bevel gear 10 to rotate through the rotating shaft 9, and the second bevel gear 10 drives the first bevel gear 7 at one end of the pressure roller 6 to rotate, thereby driving the two pressure rollers 6 to rotate in the same direction, so as to smooth the wrinkled plastic film to both sides. At the same time, when the plastic film passes between the pressure roller 6 and the driving roller 2, the plastic film can be flattened, improving the effect of flattening the plastic film; at the same time, by rotating the bolt 19, the slider 18 is driven to move inside the frame body 17, thereby driving the tension roller 16 to be adjusted forward and backward, so as to adjust the tension degree of the plastic film winding, and the flatness of the plastic film can be improved; when the plastic film is flattened, it first passes between the driving roller 2 and the pressure roller 6, and then passes through the connecting roller 15 and is wound around the outside of the tension roller 16, so as to ensure the flatness of the plastic film.
