Description

Technical Field

[0001] This utility model relates to the field of vacuum forming door panel processing technology, and in particular to a hot pressing device for bonding vacuum forming door panels. Background Technology

[0002] Vacuum-formed doors are a term that combines the material and the process. "Vacuum" refers to the vacuum suction process; "formed" refers to the surface PVC film; "formed" refers to the door panel before the PVC film is pressed onto it after milling; and "pressed" refers to the pressure applied during the PVC film forming process. It is simply called a vacuum-formed door.

[0003] Most vacuum-formed door panels are made of two or more different boards as the base material during production. After the two or more different boards are initially bonded together with adhesive, they are sent into a door panel hot press machine for pressure and heating to cure the adhesive and finally shape the board.

[0004] Existing hot pressing devices have the following drawbacks in practical use:

[0005] When hot pressing the sheet material, it is necessary to place the sheet material into the feeding frame to limit the position of multi-layer sheet material and prevent misalignment during hot pressing. After hot pressing, since the sheet material is located in the feeding frame, it is inconvenient for the staff to remove the sheet material from the feeding frame, which makes the operation time-consuming and labor-intensive and reduces the efficiency of hot pressing the sheet material. Utility Model Content

[0006] In the existing technology, when hot pressing sheet materials, it is necessary to place the sheet materials into a feeding frame to limit the movement of multiple layers of sheet materials to prevent misalignment during hot pressing. After hot pressing, the sheet materials are located in the feeding frame, making it inconvenient for workers to remove them. This results in time-consuming and labor-intensive operations, reducing the efficiency of hot pressing. This utility model provides a hot pressing device for bonding vacuum-formed door panels.

[0014] The beneficial effects of this utility model are:

[0015] This invention utilizes a lifting mechanism to lift the sheet material within the feeding frame after hot pressing, allowing the sheet material to move out of the feeding frame. This facilitates the handling of the sheet material by workers, reduces unloading time, and improves the efficiency of hot pressing processing.

The device includes a pulley 21 and an electric telescopic rod 22, which are fixedly installed at the bottom of the inner wall of the installation cavity 25. A lifting inclined plate 23 is fixedly installed at the output end of the electric telescopic rod 22. The pulley 21 is in contact with the lifting inclined plate 23, and the lifting inclined plate 23 is slidably connected to the bottom of the inner wall of the installation cavity 25.

[0027] Reference Figure 2 and Figure 3 As shown, a moving mechanism 4 is provided between the inner walls of the support frame 2. The moving mechanism 4 includes a limiting slide plate 9, a fixed plate 10, a support leg 11, and a universal wheel 12. There are two of each of the limiting slide plate 9, the support leg 11, and the universal wheel 12. Both sides of the inner wall have limit grooves 13. Limiting slide plates 9 are slidably installed in the limit grooves 13. The limiting slide plates 9 are fixedly connected to the feeding frame 8.

The guide rod 7 can ensure the stability of the hot pressing plate 6 when it is raised and lowered.

[0029] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0030] In use, after the sheet material is hot-pressed, the stepper motor 15 is started to drive the threaded rod 16 to rotate. The rotation of the threaded rod 16 drives the threaded slider 17 to move. The movement of the threaded slider 17 drives the feeding frame 8 to move. The movement of the feeding frame 8 drives the support leg 11 and the universal wheel 12 to move through the limiting slide plate 9 and the fixing plate 10. The support leg 11 and the universal wheel 12 support one end of the extended feeding frame 8, ensuring the stability of the feeding frame 8 after it is extended. Then, the electric telescopic rod 22 is started, which drives the lifting inclined plate 23 to move. The movement of the lifting inclined plate 23 causes the pulley 21 to move upward along the inclined surface. The upward movement of the pulley 21 drives the lifting column 20 to move upward. The upward movement of the lifting column 20 drives the lifting plate 19 to move upward. Thus, the lifting plate 19 can lift the sheet material in the feeding frame 8, allowing the sheet material to move out of the feeding frame 8, making it easier for workers to pick up the sheet material and reducing the unloading time.
