The other end of each of the connecting rods is fixedly connected to a limiting plate. A contact plate is slidably connected to the outside of every two connecting rods. A return spring is sleeved on the outside of each of the connecting rods. The return springs abut against the contact plate and the limiting plate. A pull plate is fixedly connected to one side of the contact plate through a side plate. An insert plate is fixedly connected to the other side of the contact plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] In this automatic hot-pressing device for leather bonding, through the configuration of a drive assembly, an installation assembly, and an auxiliary assembly, when leather bonding is required, the leather, adhesive film, and leather are first stacked sequentially on the lower mold. Then, the auxiliary assembly is installed. After the auxiliary assembly is installed, the drive assembly starts operating, simultaneously moving a moving plate.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1 - Figure 7 As shown, this embodiment provides an automatic hot pressing device for leather bonding, including a support platform 1, and further comprising:
[0030] The movable plate 2 is located above the support platform 1. The bottom of the movable plate 2 is symmetrically provided with a base plate 5. The bottom of the two base plates 5 is fixedly connected with a guide plate 6. The upper surface of the support platform 1 is symmetrically provided with a guide rail 7. The interior of the two guide plates 6 is provided with a guide groove for the guide rail 7 to move.
[0031] The drive component is located at the bottom of the support platform 1;
[0032] The positioning frame 14 is fixedly connected to the upper surface of the movable plate 2. The interior of the positioning frame 14 is provided with a connecting plate 12, and the upper surface of the connecting plate 12 is fixedly connected with a lower mold 13.
[0033] The mounting components are symmetrically arranged on both sides of the outer wall of the positioning frame 14;
[0034] The hot press 4 is fixedly connected to the outside of the support platform 1 via the support frame 3;
[0035] Auxiliary components are symmetrically arranged on the upper surface of the movable plate 2.
[0036] The working principle is as follows: When leather bonding is required, simply stack the leather, adhesive film, and leather separately on the lower mold 13, then install the auxiliary components. After the auxiliary components are installed, the drive component starts operating, moving the moving plate 2 synchronously. When the moving plate 2 is directly below the hot press 4, the hot press 4 starts operating, simultaneously pressing the auxiliary components. The auxiliary components then simultaneously press the leather, adhesive film, and leather on the lower mold 13, thus bonding the leather. When the specifications of the lower mold 13 need to be adjusted... When the shape needs to be changed (when it is not necessary to perform hot pressing treatment on the leather to a specific shape, simply replace the lower mold 13 with a flatter mold, and then the leather can be simply hot-pressed and bonded), the connecting plate 12 and the positioning frame 14 can be easily disassembled by installing the components. This makes it easy for the staff to change and adjust the shape of the lower mold 13 without the need for the staff to use bolts or other tools. This effectively improves the disassembly and assembly efficiency of the lower mold 13, reduces the workload of the staff, improves the bonding efficiency of the leather, and effectively improves the overall practicality of the device.
[0037] To effectively adjust the position of the movable plate 2, the drive assembly includes a reciprocating motor 20 fixedly connected to the bottom of the support platform 1. The output shaft of the reciprocating motor 20 is fixedly connected to a drive rod 15 via a coupling. A transmission plate 16 is fixedly connected to the top of the drive rod 15. Connecting blocks 18 are symmetrically arranged at the bottom of the movable plate 2. A sliding rod 19 is fixedly connected between the two connecting blocks 18. A slider 17 is slidably connected to the outside of the sliding rod 19. The slider 17 is hinged to the transmission plate 16. When it is necessary to adjust the position of the movable plate 2, the reciprocating motor... When the machine 20 starts running, the reciprocating motor 20 will drive the drive rod 15 to rotate synchronously. The drive rod 15 will then drive the transmission plate 16 to move synchronously. Since the transmission plate 16 and the slider 17 are hinged to each other, the transmission plate 16 will drive the slider 17 to move synchronously outside the slide rod 19. During the movement of the slider 17, it will drive the moving plate 2 to move synchronously. At this time, the position of the moving plate 2 can be adjusted. Through the setting of the guide plate 6 and the guide rail 7, the stability of the moving plate 2 during the movement can be effectively improved.
[0038] Considering that the lower mold 13 needs to be fixedly installed before the leather is hot-pressed and bonded, the installation assembly includes connecting rods 24 symmetrically arranged on both sides of the outer wall of the positioning frame 14. Each connecting rod 24 has a limiting plate 25 fixedly connected to its other end. A contact plate 26 is slidably connected to the outside of every two connecting rods 24. A return spring 27 is sleeved on the outside of each connecting rod 24, and the return springs 27 abut against the contact plate 26 and the limiting plate 25. A pull plate is fixedly connected to one side of the contact plate 26 via a side plate 28, and an insert plate 29 is fixedly connected to the other side of the contact plate 26. Guide grooves for the insert plate 29 to move are provided on both sides of the outer wall of the positioning frame 14 and the connecting plate 12. When the lower mold 13 needs to be fixedly installed, simply pull the pull plate first. The pull plate will then move the side plate 28 synchronously, and the side plate 28 will then move the contact plate 26 synchronously outside the connecting rods 24. During the movement of the contact plate 26, the return spring 27 is compressed. The contact plate 26 also drives the insert plate 29 to move synchronously. At this time, the connecting plate 12 is inserted into the interior of the positioning frame 14, and then the pull plate is released. At this time, the return spring 27 returns to its original position, driving the contact plate 26 and the insert plate 29 to move synchronously. When the insert plate 29 is inserted into the guide grooves on both sides of the outer wall of the connecting plate 12, the connecting plate 12 and the positioning frame 14 can be fixed. At this time, the lower mold 13 can be fixedly installed, which facilitates the device to perform hot pressing and bonding treatment on the leather in a specified shape. At the same time, it is convenient for the staff to disassemble and replace the lower mold 13 according to its specifications and shape, effectively improving the disassembly and assembly efficiency of the lower mold 13 and reducing the workload of the staff. When only a single bonding treatment of leather is required, the lower mold 13 can be replaced with a flatter mold, which effectively improves the overall practicality of the device.
[0039] In order to effectively extend the service life of the return spring 27, a bellows cover 30 is provided on the outside of each of the multiple connecting rods 24. The two ends of the bellows cover 30 are fixedly connected to the opposite side of the contact plate 26 and the limiting plate 25, respectively. The bellows cover 30 can effectively protect the return spring 27 from dust and water, thereby effectively preventing the return spring 27 from rusting and extending its service life, without affecting the normal use of the return spring 27.
[0040] In order to effectively improve the overall stability of the device, multiple support columns 10 are fixedly connected to the upper surface of the moving plate 2. Each of the multiple support columns 10 is fixedly connected to a support plate 11. Through the setting of the support columns 10 and the support plate 11, the lower mold 13 can be effectively supported, thereby effectively improving the overall stability of the device during the bonding process of the leather.
[0041] In addition, to effectively improve the bonding effect of the leather, the auxiliary components include auxiliary frames 8 symmetrically arranged on the upper surface of the moving plate 2. Damping rods 21 are evenly spaced at the bottom of the inner part of each auxiliary frame 8. A lower pressure plate 22 is fixedly connected to the telescopic ends of the damping rods 21. Abutment springs 23 are fitted around the outside of each damping rod 21, and these springs abut against the lower pressure plate 22 and the auxiliary frames 8. An auxiliary plate 9 is located above the moving plate 2. Guide grooves for the movement of the auxiliary plates 9 are opened on the upper surfaces of both auxiliary frames 8. When bonding the leather is required, simply insert the auxiliary plates 9 into the interior of the two auxiliary frames 8. At this time, the hot pressing equipment 4 starts operating, and the hot pressing... The device 4 presses down the auxiliary plate 9, which in turn moves the pressure plate 22 synchronously. During the movement of the pressure plate 22, the contact spring 23 and the damping rod 21 are simultaneously squeezed. When the bottom of the auxiliary plate 9 touches the outside of the leather, the leather can be effectively bonded through the cooperation between the auxiliary plate 9 and the hot pressing device 4. This avoids damage to the leather caused by the hot pressing device 4 and effectively improves the bonding effect of the leather. After the leather is bonded, the hot pressing device 4 resets. At this time, the damping rod 21 and the contact spring 23 reset synchronously, thereby moving the pressure plate 22 and the auxiliary plate 9 synchronously back to their original positions.
