[0035] Each set of limiting components is provided with a pushing device at both ends. The pushing device includes an elastic telescopic component and a reset block 24.

A sponge 16 is provided on the limit block 15.

[0037] Furthermore, a PLC controller is installed on rack 1.

[0038] The working principle of this technical solution is as follows:

[0039] Board positioning: Place the board to be coated on the belt conveyor 2 between two adjacent sets of limiting components. Each set of limiting components consists of two parallel limiting bars 14. The two sides of the board are laterally limited by positioning blocks 17 to ensure that the board is centered. The gap between the limiting bars 14 is reserved as the cutting channel of the cutter 27.

[0040] Film preparation: The film roll is installed on the film roller 6, and the film body is drawn out and covered on the upper surface of the board.

[0041] Lamination and conveying process: Start belt conveyor 2, the belt drives the limiting components and the plate to move forward at a uniform speed, and the film is continuously bonded to the plate under the pressure of pressure roller 3 to complete the lamination.

[0042] Linkage of limit components: Each limit component is equipped with a pushing device at both ends. When the limit component moves to the automatic film cutting station, the movable rod 23 of the pushing device contacts the end of the moving frame 13. Under the action of belt thrust, the movable rod 23 pushes the moving frame 13, so that the moving frame 13 moves synchronously with the limit component.

[0043] Automatic film cutting process: When the moving frame 13 moves, the movable column 31 fixed on it contacts the inclined plate 18 of the guide plate assembly. The inclined surface of the inclined plate 18 forces the cutter mounting rod 26 to press down. The cutter mounting rod 26 overcomes the elastic force of the first spring 29 and moves down, so that the cutter 27 is inserted into the gap of the limiting stop strip 14. When the movable column 31 moves to the triangular plate structure at the junction of the inclined plate 18 and the flat plate 19, the cutter 27 drops to the lowest point and cuts the film between the two adjacent plates.

[0044] Reset Phase: After the membrane is cut, the reset block 24 disengages from the wedge block 25. During the process of the reset block 24 contacting the inclined surface of the wedge block 25, the movable rod 23 retracts into the sleeve 22 under the action of the second spring 30, realizing the automatic separation of the movable rod 23 from the moving frame 13. After the reset block 24 separates from the wedge block 25, the moving frame 13 is released from the thrust constraint. The spring spring 20 pulls the moving frame 13 along the slide rail of the frame 1 to reset through the pull rope 21. The reset endpoint is positioned by the limit block 15, and the sponge 16 on its surface buffers the collision. During the reset process of the moving frame 13, the movable column 31 slides along the side of the plate 19. When it disengages from the plate 19, the cutter 27 and the movable column 31 return to the initial high position.

[0045] Cyclic operation: When the next set of limit components moves the sheet to the film cutting station, the push device triggers the moving frame 13 to move again, repeating the cutting process to achieve continuous film coating operation.

[0046] This technical solution has the following advantages:

[0047] 1. The film cutting is triggered by mechanical linkage, eliminating the need for additional sensors and ensuring strict synchronization between the cutting action and the board conveying. No machine stoppage is required during the cutting process, thus improving work efficiency.

[0048] 2. The spring 20 provides the restoring force, and with the cooperation of the guide plate assembly, the movable column 31, the first elastic component and the second elastic component, the movable frame 13 can be quickly and accurately reset.

[0050] like Figure 1 and Figure 2 As shown, the sheet laminating machine proposed in this embodiment, compared with the first embodiment, the laminating device in this embodiment includes a pressure roller 3, a first fixed frame 4 and a roller frame 5.

[0051] In this embodiment, rotating the handwheel 9 drives the threaded rod 8, causing the roller frame 5 to move down along the first guide rod 10, so that the pressure roller 3 presses the film and the surface of the board to achieve pre-bonding; the handwheel 9 can adjust the height of the pressure roller 3 to adapt to different thicknesses of boards and films, ensuring uniform bonding.
