Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present invention.

[0023] Refer to Figures 1 - 4 , a cardboard film laminating device, including a frame body 1. A conveyor belt 3 is arranged between the inner walls on both sides of the frame body 1. Baffles 5 are fixed on both sides of the top of the frame body 1 by bolts. A second fixing frame 4 is fixed on the top of the frame body 1 by bolts. Sliding grooves 19 are formed on both sides of the second fixing frame 4. An installation frame 13 is slidably connected in the two sliding grooves 19. A guiding groove 14 is formed at the bottom of the installation frame 13. Two sliding frames 15 are arranged in the guiding groove 14. A power mechanism for adjusting the positions of the two sliding frames 15 is arranged between the two sides of the installation frame 13. One side of each of the two sliding frames 15 is rotatably connected with a roller 17. A heating plate 16 is arranged on the circumferential outer wall of the roller 17. A cutting assembly for cutting the film is arranged on the top of the frame body 1. A straightening assembly for tensioning the film is arranged on the top of the installation frame 13. An extrusion plate 20 is welded to the bottom of the installation frame 13. Tension springs 18 are fixed to the bottoms of both ends of the installation frame 13 by bolts, and the other ends of the tension springs 18 are fixed to the sliding grooves 19. By changing the positions of the two sliding frames 15 through the power mechanism, the positions of the two sliding frames 15 are matched with the size of the cardboard. The cardboard is placed on the conveyor belt 3, and the film is attached to the cardboard. The conveyor belt 3 is started, and the cardboard and the film are assisted and extruded by the extrusion plate 20, so that the film better adheres to the cardboard. The heating plate 16 cuts the film extending out of both sides of the cardboard, and the cutting assembly cuts the film connecting the two cardboards, completing the film lamination of the cardboard and improving the versatility of the device.

[0024] In the present invention, the power mechanism includes a bidirectional lead screw 12. The bidirectional lead screw 12 is rotatably connected between the inner walls on both sides of the installation frame 13. Both ends of the bidirectional lead screw 12 pass through the installation frame 13 and are welded with hexagonal blocks. The bidirectional lead screw 12 is threadedly connected with the two sliding frames 15. By rotating the bidirectional lead screw 12 through the hexagonal block, the sliding frame 15 is driven to slide in the guiding groove 14. The structure is simple and the manufacturing cost is low.

[0025] Among them, the cutting component includes a first fixing frame 2, which is fixed to the top of the frame body 1 by bolts. An electric telescopic rod 6 is fixed to the outer wall of the top of the first fixing frame 2 by bolts. The piston rod of the electric telescopic rod 6 passes through the first fixing frame 2 and is fixed to a connecting plate 7 by bolts, and the connecting plate 7 slides within the first fixing frame 2. A heating rod 8 is provided at the bottom of the connecting plate 7. When the electric telescopic rod 6 is started, the electric telescopic rod 6 drives the connecting plate 7 and the heating rod 8 to move downward, making the heating rod 8 contact the film and cutting the film. The film can be cut at any position according to the setting, further improving the applicability of the device.

[0026] Among them, the straightening component includes a lower pressing plate 11, which is slidably connected to the top of the mounting frame 13 through guide rods. Two fixing columns 10 are welded to the top of the lower pressing plate 11. A counterweight 9 is sleeved on the circumferential outer sides of the two fixing columns 10. Mounting grooves 21 are formed on the opposite sides of the lower pressing plate 11 and the mounting frame 13. An auxiliary roller 22 is rotatably connected between the inner walls on both sides of the mounting groove 21. The auxiliary roller 22 reduces the friction between the film and the lower pressing plate 11 and the mounting frame 13, avoiding wear of the film. The film passes through between the lower pressing plate 11 and the mounting frame 13. The counterweight 9 presses the lower pressing plate 11 downward, causing the two auxiliary rollers 22 to squeeze the film and assisting in straightening the film, thus avoiding film bending and resulting in failed film pasting, and improving the film pasting success rate of the device.

[0027] Working principle: During use, the two-way lead screw 12 is rotated through the hexagonal block, thereby driving the carriage 15 to slide within the guide groove 14, making the positions of the two carriages 15 match the size of the cardboard. The cardboard is placed on the conveyor belt 3, and the film is attached to the cardboard. The conveyor belt 3 is started, and the cardboard and the film are assisted and squeezed by the pressing plate 20, making the film better adhere to the cardboard. The heating plate 16 cuts the film that extends beyond both sides of the cardboard. The electric telescopic rod 6 drives the connecting plate 7 and the heating rod 8 to move downward, making the heating rod 8 contact the film and cutting the film connected between the two cardboards, completing the film pasting of the cardboard.

[0028] Finally, it should be noted that: For those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
