[0019] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. Example

[0020] See Figures 1 to 3 In an embodiment of the utility model, a PET film wrinkle removal device for ribbon production includes a support frame 1, and fixed blocks 7 are provided at the left and right ends of the bottom center of the support frame 1. Guide rollers 8 are installed on the fixed blocks 7. The setting of the guide rollers 8 can guide the PET film, and the PET film can be assisted in flattening during the transportation and movement process.

[0021] Openings 5 ​​are provided on the left and right side walls of the support frame 1, and first squeezing rollers 6 are symmetrically arranged at the upper and lower ends of the openings 5. The first squeezing rollers 6 can extrude, flatten and dewrinkle the PET film made of the ribbon, and can facilitate the guiding processing of the PET film made of the ribbon, thereby facilitating the dewrinkling processing of the PET film made of the ribbon.

[0022] The top center of the support frame 1 is connected to the arc-shaped connecting frame 13 through an elastic connecting component. Several second squeezing rollers 14 are arranged at equal intervals inside the arc-shaped connecting frame 13. The elastic connecting component is used to elastically connect the support frame 1 and the arc-shaped connecting frame 13. The several second squeezing rollers 14 are used to extrude and flatten the PET film, thereby facilitating the wrinkle removal of the PET film.

[0023] The elastic connection assembly includes a first connecting tube 9 fixedly connected to the top of the support frame 1. The top end of the first connecting tube 9 is connected to the connecting block 11 through a connecting spring 10. A connecting rod 12 is provided at the bottom of the connecting block 11. The connecting rod 12 is connected to the arc-shaped connecting frame 13. The second squeezing roller 14 moves upward under the squeezing of the hot flattening roller 20. The second squeezing roller 14 pushes the arc-shaped connecting frame 13 to drive the connecting rod 12 to move upward. The connecting rod 12 drives the connecting block 11 to move upward to squeeze the connecting spring 10. The compression of the connecting spring 10 generates elastic force, which can ensure that the second squeezing roller 14 fits tightly on the surface of the PET film made of the ribbon to perform extrusion and wrinkle removal.

[0024] A telescopic rod 15 is embedded on the support frame 1 at the bottom of the second squeezing roller 14, and a mounting frame 16 is fixed on the top of the telescopic rod 15. The front and rear inner walls of the mounting frame 16 are connected to the connecting shaft 19 through connecting bearings 18. A hot flattening roller 20 is arranged between the connecting shafts 19. A ventilation cavity 28 is provided inside the hot flattening roller 20, and a plurality of ventilation holes 21 are opened at equal intervals on the outer wall of the ventilation cavity 28. The mounting frame 16 is driven to move by the telescopic rod 15, and the mounting frame 16 is tightly connected to the hot flattening roller 20 through the connecting bearings 18 and the connecting shaft 19, which can facilitate the flattening of the PET film. The setting of the ventilation holes 21 can facilitate the ventilation holes 21 inside the ventilation cavity 28 to achieve heating and flattening of the PET film.

[0025] The front and rear ends of the bottom of the installation frame 16 are provided with guide rods 17, which are slidably connected to the support frame 1. When the installation frame 16 moves, the guide rods 17 guide the installation frame 16, thereby ensuring that the installation frame 16 moves smoothly.

[0026] The second connecting pipe 22 is inserted into the front and rear ends of the mounting frame 16. The second connecting pipe 22 passes through the connecting bearing 18 and the connecting shaft 19 and is inserted into the ventilation cavity 28. The setting of the second connecting pipe 22 can facilitate the hot air heating treatment of the ventilation cavity 28.

[0027] A heater 24 is provided on the top of the support frame 1, and an exhaust assembly is provided at one end of the heater 24. The exhaust assembly is connected to the second connecting pipe 22 through a connecting hose 23. An exhaust pipe 27 is provided at the other end of the heater 24. The exhaust pipe 27 is connected to the second connecting pipe 22 through the connecting hose 23. It is heated by the heater 24, and the connecting hose 23 and the second connecting pipe 22 are connected through the exhaust assembly to achieve heating treatment of the inside of the ventilation cavity 28. The hot air is re-added to the inside of the heater 24 through the second connecting pipe 22, the connecting hose 23 and the exhaust pipe 27 for circulating ventilation and heating treatment, so that the PET film can be conveniently heated and flattened.

[0028] The exhaust assembly includes an exhaust pump 25 fixedly mounted on the outer wall of the heater 24. An exhaust pipe 26 is provided at the outer end of the exhaust pump 25. The exhaust pipe 26 is connected to the connecting hose 23. The exhaust pump 25 is used to add the hot air inside the heater 24 to the inside of the connecting hose 23 through the exhaust pipe 26, and the second connecting pipe 22 is used to heat the inside of the ventilation cavity 28, thereby enabling the hot flattening roller 20 to be heated. Example

[0029] In another embodiment of the present invention, this embodiment is different from the above embodiment in that rolling components are provided at the four corners of the bottom of the support frame 1 to facilitate the movement of the equipment. The rolling components include support legs 2 fixedly connected to the support frame 1, and rollers 3 are provided at the bottom of the support legs 2. The outer end of the roller 3 is provided with a brake 4. The setting of the roller 3 and the brake 4 can facilitate the control of the movement and fixation of the equipment, thereby facilitating the use of the device.

[0030] The working principle of the utility model is as follows: the utility model performs preliminary wrinkle removal on the PET film used for making ribbons by placing the PET film used for making ribbons on the first squeezing rollers 6 set at both ends, and then places the film on the outer surface of the hot flattening roller 20 through the guide roller 8. The installation frame 16 is driven by the telescopic rod 15 to move upward under the guidance of the guide rod 17. The installation frame 16 drives the hot flattening roller 20 to drive the PET film used for making ribbons to move upward for flattening. In the process of flattening, the film is heated by punching air through the heater 24, and the exhaust pump is used to pump the film. 25 works, the exhaust pipe 26 adds the heated hot air into the ventilation chamber 28 through the connecting hose 23 and the second connecting pipe 22, and heats, stretches and flattens the film on the surface of the hot flattening roller 20 through the ventilation hole 21. The hot flattening roller 20 moves upward to squeeze the second squeezing roller 14 to move upward. The second squeezing roller 14 drives the connecting block 11 to move upward synchronously inside the first connecting pipe 9 through the arc-shaped connecting frame 13 and the connecting rod 12. The connecting spring 10 is compressed to generate elastic force, which ensures that the second squeezing roller 14 can squeeze and flatten the film, thereby facilitating the production of ribbons.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
