[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] like Figure 1 As shown, this utility model provides a technical solution: a laminating device for plywood production, comprising:

[0030] The frame 1 has multiple conveying rollers 2 rotatably arranged inside the frame 1, and a U-shaped mounting plate 11 with its opening facing downward is provided on the top of the frame 1. A pressing roller 10 for pressing and coating plywood is rotatably arranged inside the U-shaped mounting plate 11.

[0031] The top of the frame 1 is provided with a U-shaped support plate 3 with the opening facing downward. A pair of mounting grooves 5 connected to the inner wall of the U-shaped mounting plate 11 are symmetrically opened on the side of the U-shaped support plate 3 away from the U-shaped mounting plate 11. A mounting block 6 is provided inside each pair of mounting grooves 5. A take-up roller 7 for unwinding the film is rotatably arranged between the pair of mounting blocks 6.

[0032] The top of the U-shaped mounting plate 11 is equipped with a clamping assembly 8 for pressing the mounting block 6. This design allows the clamping assembly 8 to release pressure on the mounting block 6. Then, by applying force to the take-up roller 7, the mounting block 6 is disengaged from the mounting groove 5, and the take-up roller 7 is disengaged from the U-shaped mounting plate 11, facilitating its removal. By applying force to the take-up roller 7, which has the mounting block 6 attached and the film wound around it, a pair of mounting blocks 6 are placed inside the corresponding mounting groove 5. When the mounting block 6 is tightly fitted into the mounting groove 5, the clamping assembly 8 clamps the mounting block 6, completing the placement and fixing of the take-up roller 7. This facilitates the replacement of the take-up roller 7, saves replacement time, and improves lamination efficiency.

[0033] Reference Figure 3 , Figure 4 and Figure 6 The pressing assembly 8 includes a guide groove 82 formed on the inner wall of the U-shaped support plate 3 and connected to the mounting groove 5. The guide groove 82 is located above the mounting groove 5, and a pressing block 81 is disposed inside the guide groove 82. A pressing electric push rod 83 connected to the pressing block 81 is disposed on the top of the U-shaped support plate 3. This design uses the pressing electric push rod 83 in the pressing assembly 8 to drive the pressing block 81 to move vertically along the guide groove 82, causing the pressing block 81 to fit or separate from the mounting block 6, facilitating the pressing operation of the mounting block 6 and improving the stability of the take-up roller 7 when unloading the film.

[0034] Reference Figure 1 and Figure 2 The mounting block 6 has a force-applying rod 4 located inside the mounting groove 5 on the side away from the U-shaped mounting plate 11, with the end of the force-applying rod 4 fitting against the side wall of the U-shaped mounting plate 11. This design of the force-applying rod 4 facilitates the application of force to the mounting block 6 and makes it easy to place and remove the mounting block 6.

[0035] Reference Figure 5 , Figure 7 and Figure 8 The top of the U-shaped mounting plate 11 is provided with a lifting drive assembly 9 for driving the pressure roller 10 to move in the vertical direction;

[0036] The lifting drive assembly 9 includes a lifting electric push rod 91 mounted on the top of the U-shaped mounting plate 11. A U-shaped frame 92, with its opening facing downwards, is mounted on the telescopic shaft of the lifting electric push rod 91 and is located inside the U-shaped mounting plate 11. The film pressing roller 10 is rotatably mounted inside the U-shaped frame 92. This design allows the lifting electric push rod 91 in the lifting drive assembly 9 to drive the U-shaped frame 92 to move vertically, which in turn drives the film pressing roller 10 to move vertically, facilitating the pressing operation of the film.

[0037] Reference Figure 1 , Figure 5 and Figure 7Inside the frame 1, a guide roller 12 is rotatably located directly below the pressing roller 10, and a drive motor 13 connected to the guide roller 12 is provided on the side wall of the frame 1.

[0038] The upper surface of the guide roller 12 is flush with the upper surface of the conveyor roller 2, and the guide roller 12 is located between adjacent conveyor rollers 2. This design drives the guide roller 12 to rotate through the operation of the drive motor 13. The guide roller 12 interacts with the film pressing roller 10 to coat the plywood with film while moving the coated plywood along the upper surface of the conveyor roller 2.

[0039] Reference Figure 3 , Figure 4 and Figure 6 A connecting bearing 61 is provided at the connection between the take-up roller 7 and the mounting block 6. This design improves the stability of the take-up roller 7 when unloading the film by means of the connecting bearing 61.

[0040] Reference Figures 1-8 As an embodiment of this utility model: when it is necessary to laminate plywood, the worker places the film on the surface of the plywood by taking up the roller 7; then, the lifting electric push rod 91 in the lifting drive assembly 9 drives the U-shaped frame 92 to move downward, and the downward movement of the U-shaped frame 92 drives the pressure roller 10 to move downward and fit against the upper end face of the film. Under the action of the pressure roller 10 and the guide roller 12, the film is ensured to fit against the upper end face of the plywood; finally, the drive motor 13 drives the guide roller 12 to rotate, and the rotation of the guide roller 12 cooperates with the pressure roller 10 to move the laminated plywood along the surface of the conveyor roller 2.

[0041] After the film on the take-up roller 7 is used up, the electric push rod 83 in the pressing assembly 8 drives the pressing block 81 to move upward and release the pressure on the mounting block 6. Then, the force rod 4 applies force to the take-up roller 7, causing the mounting block 6 to disengage from the mounting groove 5 and the take-up roller 7 to disengage from the U-shaped mounting plate 11, making it easy to remove the take-up roller 7. By applying force to the take-up roller 7 with the mounting block 6 and the film wrapped around it, a pair of mounting blocks 6 are placed in the corresponding mounting groove 5. When the mounting block 6 is tightly fitted with the mounting groove 5, the electric push rod 83 in the pressing assembly 8 drives the pressing block 81 to move downward and press the mounting block 6, completing the placement and fixing of the take-up roller 7. This facilitates the replacement of the take-up roller 7, saves replacement time, improves film coating efficiency, and enhances the practicality of this utility model.
