[0001] This utility model relates to the field of adhesive device technology, and in particular to a TPU film lamination adhesive device. Background Technology

[0002] In the industrial production of TPU film, the lamination and bonding process is a crucial step, playing a decisive role in improving the overall performance of the film and expanding its application range. TPU film, with its excellent elasticity, abrasion resistance, oil resistance and good biocompatibility, is widely used in many industries such as footwear, clothing, automotive interiors, and medical equipment.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: In the actual production process of TPU film, due to the different requirements of different customers for the specifications and performance of the film, it is often necessary to replace guide rollers of different materials, sizes or surface properties according to specific needs. The guide roller installation structure of existing TPU film lamination bonding devices often adopts a fixed design. The guide roller is tightly fixed to the equipment frame through complex mechanical connection methods, such as welding, riveting or permanent connection with high-strength bolts. This design makes the disassembly and replacement process of the guide roller extremely cumbersome, requiring professional tools and a large amount of manpower, and the replacement time is long. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of difficulty in replacing guide rollers, which leads to limited production flexibility. To this end, we propose a TPU film lamination bonding device.

[0021] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0022] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a TPU film lamination bonding device, including a bonding device body 1, a support frame 2 fixedly connected to both sides of the rear end of the bonding device body 1, a guide roller 3 provided on the facing surface of the support frame 2, an adjustment groove 4 provided on both sides of the guide roller 3, an adjustment column 5 rotatably connected inside the adjustment groove 4, a control groove 6 provided at both ends of the adjustment column 5, a push block 7 slidably connected inside the control groove 6, a control rod 8 fixedly connected to the side of the push block 7 near the inside of the control groove 6, an arc-shaped block 9 fixedly connected to both ends of the guide roller 3, a connecting rod 11 slidably connected inside the support frame 2, and a limiting groove 12 provided at both ends of the connecting rod 11;

[0023] Specifically: The worker places the guide roller 3 in the middle of the support frame 2 and inserts the connecting rod 11 through the inside of the support frame 2 into the inside of the adjusting column 5. At the same time, the worker rotates the adjusting column 5, which causes the push block 7 to gradually contact the thicker end of the arc block 9. This causes the arc block 9 to push the push block 7 and drive the control rod 8 to be inserted into the limiting groove 12, thus completing the installation of the guide roller 3.

[0024] Reference Figure 5 As shown in this embodiment: the guide roller 3 has two annular grooves 22 inside, and two annular blocks 10 are fixedly connected to the outer diameter surface of the adjusting column 5. The surface of the annular blocks 10 is slidably connected to the inside of the annular grooves 22.

[0025] Specifically, when the adjusting column 5 rotates inside the adjusting groove 4, it will drive the annular block 10 to slide inside the annular groove 22. This sliding connection design not only enhances the connection stability between the adjusting column 5 and the guide roller 3, but also ensures the smoothness of the adjusting column 5 during rotation.

[0026] Reference Figure 4 As shown in this embodiment: a return spring 13 is fixedly connected to the side of the push block 7 near the control rod 8, and the side of the return spring 13 away from the push block 7 is fixedly connected to the inside of the control groove 6.

[0027] Specifically: When the push block 7 is pushed by the arc block 9, it will compress the return spring 13 and generate a certain elastic force. This elastic force design allows the return spring 13 to quickly push the push block 7 to reset after the arc block 9 is separated from the push block 7, thereby driving the control rod 8 to be pulled out from the limiting groove 12.

[0028] Reference Figure 2 and Figure 4 As shown, in this embodiment: the size of the control rod 8 is adapted to the size of the limiting groove 12, and the surface of the control rod 8 is inserted into the interior of the limiting groove 12;

[0029] Specifically, when the control lever 8 is inserted into the limiting slot 12, the size is compatible, which ensures the stability of the control lever 8 in the limiting slot 12 and prevents it from shaking or falling off. This plug-in design not only simplifies the operation process, but also improves the reliability and safety of the device.

[0030] Reference Figure 4 As shown in this embodiment: guide grooves 14 are provided at both ends of the control groove 6, and guide blocks 15 are fixedly connected to both ends of the push block 7. The surface of the guide block 15 is slidably connected to the inside of the guide groove 14.

[0031] Specifically: When the push block 7 moves to reset under the push of the reset spring 13, the guide block 15 slides inside the guide groove 14. This sliding connection design ensures the stability and directionality of the push block 7 during movement and prevents it from deviating or getting stuck.

[0032] Reference Figure 4 As shown in this embodiment: both sides of the adjusting column 5 are provided with shrinkage grooves 16, and shrinkage blocks 17 are slidably formed inside the shrinkage grooves 16. A thrust spring 18 is fixedly connected to the side of the shrinkage block 17 close to the inside of the shrinkage groove 16, and the side of the thrust spring 18 away from the shrinkage block 17 is fixedly connected to the inside of the shrinkage groove 16. Both sides of the guide roller 3 are provided with limiting holes 19.

[0033] Specifically: When the operator rotates the adjusting column 5 to insert the control rod 8 into the limiting groove 12, the shrinking groove 16 coincides with the limiting hole 19, and under the action of the rebound force of the thrust spring 18, the shrinking block 17 is quickly inserted into the limiting hole 19 to limit the adjusting column 5.

[0034] Reference Figure 4As shown in this embodiment: both ends of the shrinkage groove 16 are provided with sliding grooves 20, and both ends of the shrinkage block 17 are fixedly connected with sliding blocks 21, and the surface of the sliding block 21 is slidably connected to the inside of the sliding groove 20.

[0035] Specifically, the design of the sliding groove 20 makes the movement of the shrink block 17 inside the shrink groove 16 more stable, effectively preventing the shrink block 17 from shifting or getting stuck during the movement. The close cooperation between the sliding block 21 and the sliding groove 20 further enhances the stability and durability of the structure.

[0036] Working principle: The operator places the guide roller 3 in the middle of the support frame 2 and inserts the connecting rod 11 through the inside of the support frame 2 into the inside of the adjusting column 5. At the same time, the adjusting column 5 is rotated, and the adjusting column 5 drives the push block 7 to gradually contact the thicker end of the arc block 9, so that the arc block 9 pushes the push block 7 and drives the control rod 8 to be inserted into the inside of the limiting groove 12, thus completing the installation of the guide roller 3.

[0037] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
