Description

Technical Field

[0001] This utility model relates to the field of laminating machine technology, and in particular to a cutting mechanism for a laminating machine. Background Technology

[0002] Window film is suitable for various applications, including residential homes, commercial buildings, and public facilities. In residential homes, window film effectively prevents injuries from accidental impacts to the glass, while also improving the thermal insulation performance of doors and windows, thus enhancing the living environment. In commercial buildings, window film not only protects doors and windows from external damage but also reduces heat transfer, lowers energy consumption, and improves the overall performance of the building.

[0003] In the prior art, patent document with publication number (CN112592045B) mentions a cutting device for coated glass production, including a workbench and multiple support seats installed on the top of the workbench. The workbench is equipped with an auxiliary cutting mechanism to facilitate the separation of finished glass and waste materials to improve glass cutting efficiency. This cutting device for coated glass production, unlike the prior art, allows workers to avoid manually breaking off the glass during cutting. Through the auxiliary cutting mechanism, finished glass and waste materials can be easily separated directly, which not only improves cutting efficiency but also prevents burrs around the glass from cutting workers' hands, thus improving safety during the cutting process.

[0004] However, the aforementioned existing technology cannot restrict the direction of the coating during transportation, making it easy for the coating to deviate and difficult to cut a regular coating. Utility Model Content

[0020] This utility model provides a cutting mechanism for a laminating machine, including a frame 1, two rotating rollers 2, two limiting rollers 3, a limiting mechanism, two limiting plates 10, two fixing rods 11, two fixing blocks 12, a tension roller 13, two springs 14, two mounting plates 7, a second lead screw 16, a round rod 17, two moving blocks 18, and two cutting wheels 19. The limiting mechanism includes a first lead screw 4, two sliding blocks 5, a limiting rod 6, a fixing plate 15, four limiting pieces 9, and two rotating wheels 8. The aforementioned solution solves the problem in the prior art that the direction of laminating cannot be restricted during transport, the laminating is prone to deviation, and it is difficult to cut a regular laminating film.

[0021] In this specific embodiment, two rotating rollers 2 are rotatably connected to the frame 1 and are evenly distributed on both sides of the frame 1. Two limiting rollers 3 are rotatably connected to the frame 1 and are located on the surface of the frame 1. The limiting mechanism is disposed between the two limiting rollers 3. The first lead screw 4 is rotatably connected to the frame 1 and is located between the two rotating rollers 2. The limiting rod 6 is fixedly connected to the frame 1 and is located on one side of the first lead screw 4. Two sliding blocks 5 are threadedly connected to the lead screw and are located at both ends of the lead screw. The sliding block 5 corresponding to the mounting plate 7 is fixedly connected and is located at the corresponding sliding block. At the upper end of 5, the rotating wheel 8 is fixedly connected to the corresponding mounting plate 7 and is located below the corresponding mounting plate 7. A first motor 20 is provided on one side of each of the two rotating rollers 2. The two rotating rollers 2 are driven by the first motor 20 to unwind and rewind the film respectively. A second motor 22 is provided on one side of the first lead screw 4. During processing, the second motor 22 drives the first lead screw 4. The threads on both sides of the first lead screw 4 are arranged in opposite directions. Under the movement of the limiting rod 6, the two sliding blocks 5 move accordingly, and the rotating wheel 8 moves to both sides of the film to clamp the film and restrict the direction of film movement.

[0022] The four limiting pieces 9 are fixedly connected to the corresponding rotating wheels 8 and are respectively set on both sides of the corresponding rotating wheels 8. The limiting pieces 9 are stuck above and below the film, which improves the stability of the film.

[0023] Secondly, the two limiting plates 10 are fixedly connected to the frame 1 and located on one side of the corresponding rotating roller 2. The surfaces of the two limiting plates 10 are provided with openings. The two fixing rods 11 are fixedly connected to the corresponding limiting plates 10 and located inside the openings. The two fixing blocks 12 are slidably connected to the corresponding fixing rods 11 and are sleeved on the surface of the corresponding fixing rods 11. The tensioning roller 13 is rotatably connected to the two fixing blocks 12 and located between the two fixing blocks 12. When transporting the film, the diameter of the film on the rotating rollers 2 on both sides changes, which will cause the tension of the film to change. The tensioning roller 13 presses on the film, which improves the stability of film transport.

[0024] Secondly, the two springs 14 cover the surface of the corresponding fixing rod 11 and are located above the corresponding fixing block 12. The springs 14 push the corresponding fixing block 12, so that the rotating roller 2 presses on the film.

[0025] In addition, the two fixed plates 15 are fixedly connected to the frame 1 and located on one side of the frame 1. The second lead screw 16 is rotatably connected to the frame 1 and located on one side of the corresponding limiting roller 3.

The two moving blocks 18 are threadedly connected to the second lead screw 16 and sleeved on the surfaces of the second lead screw 16 and the round rod 17. The two cutting wheels 19 are arranged below the corresponding moving blocks 18. A third motor 23 is arranged on one side of the second lead screw 16. The third motor 23 drives the second lead screw 16 to rotate. The threads on both sides of the second lead screw 16 are arranged in opposite directions. Under the restriction of the round rod 17, the moving blocks 18 move accordingly. A cylinder 21 is arranged above the moving blocks 18. The cylinder 21 pushes the cutting wheels 19 to cut the film.

[0026] When using this utility model, the two rotating rollers 2 are driven by the first motor 20 to unwind and rewind the film respectively. A second motor 22 is provided on one side of the first lead screw 4. During processing, the second motor 22 drives the first lead screw 4. The threads on both sides of the first lead screw 4 are arranged in opposite directions. Under the movement of the limiting rod 6, the two sliding blocks 5 move accordingly. The rotating wheel 8 moves to both sides of the film, clamps the film, and restricts the direction of film movement. When transporting the film, the diameter of the film on the rotating rollers 2 on both sides changes, which will cause the tension of the film to change. The spring 14 pushes the corresponding fixing block 12, so that the tensioning roller 13 presses on the film. The third motor 23 drives the second lead screw 16 to rotate. Under the restriction of the round rod 17, the moving block 18 moves accordingly. A cylinder 21 is provided above the moving block 18. The cylinder 21 pushes the cutting wheel 19 to cut the film.
