Description

Technical Field

[0001] This utility model relates to the field of plastic sheet processing technology, specifically to an automatic plastic sheet laminating and pressing device. Background Technology

[0002] As is well known, in the traditional sheet lamination and pressing process, the equipment usually applies downward pressure to laminate and press the sheet. The downward pressure drive device (such as cylinder, hydraulic cylinder, etc.) in traditional equipment needs to provide sufficient force to ensure that the lamination material can be tightly adhered to the sheet surface. Since each operation requires a large downward pressure, these drive components are under high load for a long time, which can easily lead to rapid wear of mechanical parts, increase maintenance frequency and maintenance costs. The operation process of many traditional equipment is relatively cumbersome, especially when changing batches of sheets of different thicknesses and sizes, which requires manual intervention to complete the adjustment steps before pressing. This not only increases labor costs, but also limits the improvement of production efficiency. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides an automatic film-coating and pressing device for plastic sheets, which has the following advantages:

[0016] This automatic plastic sheet laminating and pressing device replaces the traditional method of directly applying downward pressure with an elastic support mechanism. This reduces the direct stress on the main drive components, meaning that key mechanical parts no longer bear continuous high-load operation, effectively extending their service life and reducing equipment maintenance frequency and costs. During the lamination process, the heating mechanism heats the pressing rollers, ensuring that the laminating material receives appropriate heat treatment while being pressed. This helps the lamination adhere more firmly to the sheet surface, avoiding problems such as bubbling and wrinkling, thus improving lamination quality. The moving mechanism controls the position change of the curved plate, realizing an automated process from lamination to pressing and then stopping the operation. This simplifies the operation steps, eliminates the need for frequent manual intervention, improves work efficiency and production continuity, and ensures the consistency and reliability of each lamination and pressing operation.

[0022] 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.

[0023] Please see Figure 1-4This utility model relates to an automatic plastic sheet laminating and pressing device, comprising a worktable 1, a support plate 2 and a pressing mechanism on the worktable 1, a laminating mechanism 3 and a fixing plate 4 on the support plate 2, and a pressing mechanism including a U-shaped frame 5 and a pressing roller 6. A driving mechanism and a heating mechanism are provided between the pressing roller 6 and the U-shaped frame 5. An elastic support mechanism is provided between the top of the U-shaped frame 5 and the fixing plate 4. Arc edges 7 are formed on both sides of the bottom of one end of the U-shaped frame 5, and an arc groove is formed at the bottom of one end of the U-shaped frame 5. An arc-shaped plate 8 is provided on the arc groove, and a moving mechanism is provided between the arc plate 8 and the support plate 2. In this embodiment, the sheet material is conveyed to the worktable 1 via the conveyor belt of the previous process equipment. Then, the sheet material on the worktable 1 is coated with film by the film coating mechanism 3. Then, the moving mechanism is controlled to move the arc plate 8 away from the arc groove and to one end of the U-shaped frame 5. At this time, the arc plate 8 presses the U-shaped frame 5 upward, and the elastic support mechanism between the fixed plate 4 and the top of the U-shaped frame 5 is compressed and deformed. After the arc plate 8 leaves the bottom of the U-shaped frame 5, The elastic support mechanism provides downward elastic support to the U-shaped frame, allowing the pressing roller 6 to rest against the top of the board. Heating of the pressing roller 6 by the heating mechanism and rotation by the drive mechanism ensures the film is pressed firmly onto the board, resulting in a stable and reliable film-pressing operation. The downward pressure from the elastic support mechanism is sufficient to ensure the pressing roller 6 applies sufficient pressure to the film on the board. After film-pressing, the moving mechanism re-presses the arc plate 8 upwards along the arc edge 7 against the U-shaped frame 5. The elastic support mechanism moves upwards under pressure, and the arc plate 8 rests against the arc groove of the U-shaped frame 5, stopping the pressing operation. The pressing operation can then be restarted by controlling the moving mechanism to move the arc plate 8 linearly away from the arc groove. This structure automatically activates the elastic support mechanism to provide elastic support to the pressing roller 6, thus achieving the pressing operation after film-pressing the board. This solves the problem of traditional pressing equipment directly generating downward pressure, requiring frequent maintenance of the main drive components.

[0024] To further facilitate the rotation of the pressing roller 6, in this design, the driving mechanism includes a driving motor 9 and bearing seats 10. The bearing seats 10 are installed at both ends of the pressing roller 6 and connected to the U-shaped frame 5. The driving motor 9 is installed on the U-shaped frame 5 and connected to one end of the pressing roller 6. By controlling the output end of the driving motor 9 to rotate the pressing roller 6, the pressing roller 6 can be rotated at a stable angle through the bearing seats 10 at both ends, thereby facilitating the pressing operation of rotating the pressing roller 6.

[0025] In order to facilitate the heating operation of the pressing roller 6, in this solution, the heating mechanism includes a heating tube 11. The heating tube 11 is located inside the pressing roller 6 and installed on one side of the U-shaped frame 5. The heating tube 11 being located inside the pressing roller 6 facilitates the heating of the pressing roller 6, and the heating tube 11 being installed on one side of the U-shaped frame 5 facilitates the wiring assembly and use of the heating tube 11.

[0026] The aforementioned moving mechanism can be any type of linear moving device. In order to further improve the stability and accuracy of linear movement, in this solution, the moving mechanism includes an electric telescopic rod 12. The electric telescopic rod 12 is installed on one side of the support plate 2. A connecting frame is provided between the output end of the electric telescopic rod 12 and the arc plate 8. By controlling the output end of the electric telescopic rod 12 to move the connecting frame linearly, the connecting frame drives the arc plate 8 to move linearly, thereby facilitating the adjustment of the position of the arc plate 8.

[0027] To provide stable elastic support for the pressing roller 6, in this design, the elastic support mechanism includes a fixed column 13 and a lifting column 14. The fixed column 13 is installed at the bottom of the fixed plate 4, and a fixed groove is provided inside the fixed column 13. A lifting hole is provided at the bottom of the fixed groove. The lifting column 14 is located in the lifting hole and connected to the top of the U-shaped frame 5. A limiting plate 15 is provided between the lifting hole and the fixed groove, and an elastic component 16 is provided between the limiting plate 15 and the top of the fixed groove. The elastic component 16 in the fixed groove exerts an elastic downward pressure on the limiting plate 15. When the arc plate 8 leaves the arc groove, the pressing roller 6 can elastically press down against the plate to perform the pressing operation. The limiting plate 15 can prevent the lifting column 14 from disengaging from the lifting hole.

[0028] To improve the pressing stability, this solution includes multiple elastic support mechanisms. These multiple elastic support mechanisms can provide more balanced elastic support for the U-shaped frame 5, further improving the pressing effect.

[0029] In order to stabilize the lifting and lowering movement of the U-shaped frame 5, in this solution, a sliding groove 17 is provided on one side of the support plate 2, and a slider 18 is provided between the sliding groove 17 and one side of the U-shaped frame 5. The slider 18 in the sliding groove 17 is driven by the U-shaped frame 5 to move linearly up and down, thereby enabling the U-shaped frame 5 to move more stably in a linear manner.

[0030] The aforementioned chute 17 and slider 18 can be of any shape. In order to further improve the stability of the U-shaped frame 5 in lifting and moving, in this solution, the chute 17 and slider 18 are both T-shaped. The T-shaped chute 17 and slider 18 can further improve the stability of the U-shaped frame 5 in linear lifting and moving.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
