Description

Technical Field

[0001] This utility model relates to the technical field of thin film coating baking equipment, and in particular to a TPU thin film coating baking equipment for rapid cooling and winding. Background Technology

[0002] TPU film coatings are widely used in various fields such as medical and health, electronics, industry and sports due to their excellent high tensile strength, high tensile strength, toughness and aging resistance. In the production process of TPU film, coating baking is a crucial step that directly affects the quality and performance of the film. However, traditional TPU film coating baking equipment often faces problems of low cooling and winding efficiency after baking, which not only affects production efficiency but may also have an adverse effect on the quality of the film.

[0003] Chinese patent discloses a rapid cooling and winding TPU film coating baking device (authorization announcement number CN222057943U). This patented technology allows for the circulation of a low-temperature medium through water pipes on both sides of the cooling pipe. During use, the delivered film can be wound in an "S" shape around the outside of the heat-conducting ring for transport. The low-temperature medium flowing inside the cooling pipe cools the film on the outside, thus achieving the cooling effect of the film coating baking device.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: Due to the fixed nature of the take-up roller, these devices are inadequate when processing TPU films of different widths or sizes. For narrower films, the width of the take-up roller often exceeds the actual width of the film, causing the film to easily slip or wrinkle on the roller during the winding process, thus affecting the flatness and quality of the film. For wider films, the insufficient width of the take-up roller makes it impossible to completely wrap the film, which also affects the winding effect and the appearance of the final product. Utility Model Content

[0005] The technical problem to be solved by this invention is that the existing technology has the disadvantage of not being able to adjust the width of the winding roller. To address this, we propose a TPU film coating baking device for rapid cooling and winding.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1 - Figure 5As shown, this utility model provides a technical solution: a rapid cooling and winding TPU film coating baking device, including an operating table 1, a baking device 2 installed at the top of the operating table 1, a driving device 3 installed at the top of the operating table 1, a first winding roller 4 installed on one side of the driving device 3, a connecting rod 5 slidably connected inside the first winding roller 4, a second winding roller 6 provided on the side of the connecting rod 5 away from the first winding roller 4, a vertical plate 7 provided on the side of the second winding roller 6 away from the connecting rod 5, an adjustment groove 8 opened at the top of the operating table 1, a base plate 9 slidably connected inside the adjustment groove 8, the top of the base plate 9 being fixedly connected to the bottom of the vertical plate 7, a control groove 10 opened at the front end of the operating table 1, and a sliding groove 10 inside the control groove 10... An adjusting block 11 is dynamically connected. A through groove 12 is opened at the top of the control groove 10. An insert block 13 is fixedly connected to the top of the adjusting block 11. A straight groove 19 is opened at the bottom of the base plate 9. Several slots 20 are opened at the rear end of the straight groove 19. The operator pushes the adjusting block 11 into the control groove 10, so that the adjusting block 11 moves into the straight groove 19 and drives the insert block 13 to release the limit between it and the slot 20, so that the limit between the vertical plate 7 and the base plate 9 is also released. The operator moves the vertical plate 7, so that the vertical plate 7 drives the second winding roller 6 to move, thereby adjusting the distance between the first winding roller 4 and the second winding roller 6, thereby achieving the winding and baking of TPU film coatings of different specifications.

[0023] Reference Figure 3 and Figure 4 As shown in this embodiment: the size of the insert 13 is adapted to the size of the slot 20, and the surface of the insert 13 is inserted into the interior of the slot 20. By adapting the size of the insert 13 to the size of the slot 20, the stable positioning of the insert 13 inside the slot 20 is ensured. The driving device 3 forms friction with the inner wall of the slot 20, which further enhances the fixing effect between the insert 13 and the slot 20. In actual operation, when the adjusting block 11 is pushed into the straight groove 19, the contact surface between the insert 13 and the slot 20 will slide relative to each other due to the movement of the adjusting block 11, thereby releasing the limit of the vertical plate 7 and the bottom plate 9.

[0024] Reference Figure 2 As shown in this embodiment: sliding grooves 14 are provided on both sides of the inside of the adjusting groove 8, and a rotating shaft 15 is rotatably connected inside the vertical plate 7. Rollers 16 are fixedly connected on both sides of the rotating shaft 15. The surface of the rollers 16 is slidably connected to the inside of the sliding groove 14. When the operator moves the vertical plate 7, the vertical plate 7 drives the rollers 16 to slide inside the sliding groove 14. Through the above arrangement, the vertical plate 7 and the base plate 9 can move stably inside the adjusting groove 8.

[0025] Reference Figure 2As shown in this embodiment: a return spring 17 is fixedly connected to one side of the inside of the adjustment groove 8, and a push plate 18 is fixedly connected to one side of the return spring 17. When the operator pushes the vertical plate 7 and the bottom plate 9 into the adjustment groove 8, the vertical plate 7 pushes the push plate 18 to compress and store the return spring 17. After the operator releases the limit of the vertical plate 7 and the bottom plate 9, the push plate 18 pushes the vertical plate 7 and the bottom plate 9 to move outward a small distance under the action of the return spring 17, so that the operator can make adjustments.

[0026] Reference Figure 5 As shown in this embodiment: both ends of the first take-up roller 4 are provided with guide grooves 21, and both ends of the connecting rod 5 are fixedly connected with guide blocks 22. The surface of the guide blocks 22 is slidably connected to the inside of the guide grooves 21. When the operator moves the connecting rod 5, the connecting rod 5 drives the guide blocks 22 to slide inside the guide grooves 21. Through the above settings, the precise movement and positioning of the connecting rod 5 and the first take-up roller 4 inside the guide grooves 21 are ensured. This design not only improves the convenience of operation, but also enhances the stability and durability of the overall structure.

[0027] Reference Figure 4 As shown in this embodiment: A storage spring 23 is fixedly connected to the side of the adjusting block 11 near the inside of the control groove 10, and the side of the storage spring 23 away from the adjusting block 11 is fixedly connected to the inside of the control groove 10. When the operator pushes the adjusting block 11 into the control groove 10, the adjusting block 11 compresses the storage spring 23 to store force, and drives the insert block 13 to release the limit between itself and the slot 20. After the operator adjusts the appropriate position of the base plate 9, the insert block 13 is aligned with the control groove 10 and the adjusting block 11 is released. Under the action of the rebound force of the storage spring 23, the adjusting block 11 moves quickly to the outside and drives the insert block 13 to be inserted into the slot 20 for fixation.

[0028] Reference Figure 4 As shown in this embodiment: sliding grooves 24 are provided on both sides of the control groove 10, and sliding blocks 25 are fixedly connected to both sides of the adjustment block 11. The surface of the sliding block 25 is slidably connected to the inside of the sliding groove 24. When the operator moves the adjustment block 11, the adjustment block 11 drives the sliding block 25 to slide inside the sliding groove 24. Through the above settings, the movement trajectory of the adjustment block 11 is fixed, and the adjustment block 11 is prevented from extending too far outward and falling off.

[0029] Working principle: The operator pushes the adjusting block 11 into the control slot 10, causing the adjusting block 11 to move into the straight slot 19, and driving the insert block 13 to release its limit between itself and the slot 20. This also releases the limits of the vertical plate 7 and the bottom plate 9. The operator moves the vertical plate 7, causing it to drive the second winding roller 6 to move, thereby adjusting the distance between the first winding roller 4 and the second winding roller 6. This allows for the winding and baking of TPU film coatings of different specifications. The size of the insert block 13 is matched with the size of the slot 20, ensuring the stable positioning of the insert block 13 inside the slot 20. The drive device 3 and the slot 20... The inner wall of the slot 0 generates friction, further enhancing the fixing effect between the insert 13 and the slot 20. In actual operation, when the adjusting block 11 is pushed into the straight groove 19, the contact surfaces of the insert 13 and the slot 20 will slide relative to each other due to the movement of the adjusting block 11, thereby releasing the limit of the vertical plate 7 and the bottom plate 9. When the operator moves the vertical plate 7, the vertical plate 7 drives the roller 16 to slide inside the slide groove 14. Through the above settings, the vertical plate 7 and the bottom plate 9 can move stably inside the adjusting groove 8. When the operator pushes the vertical plate 7 and the bottom plate 9 into the adjusting groove 8, the vertical plate 7 pushes the push plate 18 to compress the return spring 1. 7. After the compression and storage process, the operator releases the limiting positions of the vertical plate 7 and the bottom plate 9. Under the rebound force of the return spring 17, the push plate 18 pushes the vertical plate 7 and the bottom plate 9 to move outward a small distance to facilitate adjustment. When the operator moves the connecting rod 5, the connecting rod 5 drives the guide block 22 to slide inside the guide groove 21. Through the above settings, the precise movement and positioning of the connecting rod 5 and the first take-up roller 4 inside the guide groove 21 are ensured. This design not only improves the convenience of operation but also enhances the stability and durability of the overall structure. When the operator pushes the adjusting block 11 into the control groove 10, the adjustment... The segment 11 compresses and stores the energy in the storage spring 23, causing the insertion block 13 to release its limit from the slot 20. After the operator adjusts the base plate 9 to the appropriate position, the insertion block 13 is aligned with the control slot 10 and the adjustment block 11 is released. Under the action of the rebound force of the storage spring 23, the adjustment block 11 moves quickly outward and causes the insertion block 13 to be inserted into the slot 20 for fixation. When the operator moves the adjustment block 11, the adjustment block 11 causes the sliding block 25 to slide inside the sliding groove 24. Through the above settings, the movement trajectory of the adjustment block 11 is fixed, while preventing the adjustment block 11 from extending too far outward and causing it to fall off.
