Description

Technical Field

[0001] This utility model relates to the field of laminating machine technology, specifically a mobile cutting device for a laminating machine. Background Technology

[0002] A laminating machine is a type of machine used to bond paper, board, and film together under pressure from rubber rollers and heated rollers to form a paper-plastic composite. It can be divided into two main categories: instant laminating machines and pre-coated laminating machines.

[0003] In the prior art, utility model patent with announcement number CN211390515U provides a mobile cutting device for a laminating machine, including a laminating machine. A base plate is fixedly connected to the laminating machine and located directly below the laminating machine's discharge port. A cutting groove is opened on the side of the base plate away from the ground and corresponding to the laminating machine's discharge port. A sliding groove is opened on the front and back of the base plate and located at the center of the base plate. An electric push rod is fixedly connected to the side of the sliding groove near the laminating machine. A slider is fixedly connected to the end of the electric push rod away from the laminating machine and located inside the sliding groove. A fixing plate is fixedly connected to the side of the slider away from the base plate and located outside the sliding groove.

[0004] The moving cutting device of the current laminating machine is unable to unfold the film in the cutting area. Wrinkles in the cutting area affect the cutting effect. It is necessary to first restrict the movement of the film on both sides of the cutter, and then move the cutter to cut. This requires two steps, which affects the use of the equipment. Therefore, we propose a moving cutting device for the laminating machine to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a mobile cutting device for a laminating machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mobile cutting device for a laminating machine, comprising a laminating machine, a worktable on one side of the laminating machine, a cutting mechanism on the worktable, the cutting mechanism being used to cut a film, the cutting mechanism including a bracket on the worktable, a telescopic rod at the top of the bracket, a movable plate connected to the extended end of the telescopic rod and used to raise and lower the movable plate, a cutter for moving and cutting the film being provided at the bottom of the movable plate, a limiting rod moving through the outer side of the cutter on the movable plate, a spring moving through the bottom of the limiting rod and connected to a pressure plate pressed on the film, the spring being used to push the pressure plate down to return to its original position, and an unfolding mechanism being provided on the pressure plate.

[0007] Preferably, the unfolding mechanism is used to unfold the film between the two sets of pressure plates.

[0008] Preferably, the unfolding mechanism includes a groove formed at the bottom of the pressure plate, a rotating shaft is rotatably provided in the groove, and a roller for pushing the film unfold is fixedly connected to the rotating shaft.

[0009] Preferably, the bracket has a U-shaped structure, the telescopic rod has a telescopic length greater than the height difference between the cutter and the bottom of the pressure plate, and the movable plate is used to support the spring and the lifting of the cutter.

[0010] Preferably, the cutter is a film cutter, and the limiting rod is provided with two sets of movable plates symmetrically distributed on both sides of the cutter, and the limiting rod is a square rod.

[0011] Preferably, the top end of the spring is connected to the bottom of the movable plate, the bottom end of the spring is connected to the top of the movable plate, and a protective layer is provided at the bottom of the pressure plate.

[0012] Preferably, one end of the rotating shaft is connected to an electric motor for driving the rotating shaft to rotate, the electric motor on the rotating shaft is mounted on the pressure plate, the roller is an elastic rubber roller, and the bottom of the roller is below the bottom of the pressure plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The extension rod extends and pushes the moving plate downward. The moving plate pushes the spring and pressure plate to move. The movement of the pressure plate causes the rotating shaft and rollers to follow. When the rollers contact the film, the extension rod stops. Then, the motor is started to drive the rotating shaft to rotate. The rotating shaft drives the rollers to rotate. The rotating rollers contact the film and push the film to unfold, so that the film in the cutting area can be unfolded, avoiding wrinkles that affect the cutting effect.

[0015] 2. After the film in the cutting area is unfolded, continue to operate the telescopic rod to push the moving plate downward. When the force on the roller exceeds the deformation force of the roller, the roller deforms, allowing the bottom of the pressure plate to contact the film. The pressure plate is then restricted from moving further downward. The moving plate moves downward and compresses the spring. The spring's reaction force pushes the pressure plate to compact the film, restricting the film's movement. At the same time, the cutter follows the moving plate and moves downward to contact the film and cut it. This restricts the movement of the film on both sides of the cutter when the moving cutter cuts, improving the equipment's efficiency. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-3 A mobile cutting device for a laminating machine includes a laminating machine 1, a worktable 2 on one side of the laminating machine 1, a cutting mechanism 3 on the worktable 2, and an unfolding mechanism 4 on a pressure plate 37. The unfolding mechanism 4 is used to unfold the film between two pressure plates 37. The unfolding mechanism 4 includes a groove 41 opened at the bottom of the pressure plate 37, a rotating shaft 42 rotatably disposed in the groove 41, and a roller 43 for pushing the film unfolding is fixedly connected to the rotating shaft 42. One end of the rotating shaft 42 is connected to a motor for driving the rotating shaft 42 to rotate. The motor on the rotating shaft 42 is disposed on the pressure plate 37. The roller 43 is an elastic anti-slip rubber roller, and the bottom of the roller 43 is below the bottom of the pressure plate 37.

[0022] The film exits from the discharge port of the laminating machine 1 and falls onto the worktable 2. The drive telescopic rod 32 extends and pushes the moving plate 33 downward. The moving plate 33 pushes the spring 36 and the pressure plate 37 to move. The movement of the pressure plate 37 causes the rotating shaft 42 and the roller 43 to move accordingly. When the roller 43 contacts the film, the drive telescopic rod 32 stops, and then the motor is started to drive the rotating shaft 42 to rotate. The rotating shaft 42 drives the roller 43 to rotate. The rotating roller 43 contacts the film and pushes the film to unfold, so that the film in the cutting area (the film between the two sets of pressure plates 37) can be unfolded, avoiding wrinkles that affect the cutting effect.

[0023] The cutting mechanism 3 is used to cut the film. The cutting mechanism 3 includes a bracket 31 mounted on the worktable 2. A telescopic rod 32 is provided at the top of the bracket 31. The extended end of the telescopic rod 32 is connected to a moving plate 33 and is used to raise and lower the moving plate 33. A cutter 34 for moving the film is provided at the bottom of the moving plate 33. A limit rod 35 moves through the moving plate 33 outside the cutter 34. A spring 36 moves through the bottom of the limit rod 35 and is connected to a pressure plate 37 pressed on the film. The spring 36 is used to push the pressure plate 37 down to restore its original position. The bracket 31 has a U-shaped structure. The telescopic rod 32 can be an electric or hydraulic telescopic rod. The telescopic length of the telescopic rod 32 is greater than the height difference between the bottom of the cutter 34 and the pressure plate 37. The movable plate 33 is used to support the lifting of the spring 36 and the cutter 34. The cutter 34 is a film cutter. The limiting rod 35 has two sets of movable plates 33 symmetrically distributed on both sides of the cutter 34. The limiting rod 35 is a square rod. The top end of the spring 36 is connected to the bottom of the movable plate 33, and the bottom end of the spring 36 is connected to the top of the movable plate 33. The bottom of the pressure plate 37 is provided with a protective layer.

[0024] After the film in the cutting area is unfolded, the telescopic rod 32 continues to be operated to push the moving plate 33 downward. When the force on the roller 43 is greater than the deformation force of the roller 43, the roller 43 deforms, allowing the bottom of the pressure plate 37 to contact the film. The pressure plate 37 is restricted from continuing to move downward. The moving plate 33 moves downward to compress the spring 36. The reaction force of the spring 36 pushes the pressure plate 37 to compact the film, restricting the movement of the film. At the same time, the cutter 34 moves with the moving plate 34. The cutter 34 moves downward to contact the film and cut the film. This restricts the movement of the film on both sides of the cutter 34 when the moving cutter 34 is cutting, improving the efficiency of the equipment.

[0025] Working Principle: The film of this invention falls onto the worktable 2 from the outlet of the laminating machine 1. The drive telescopic rod 32 extends, pushing the moving plate 33 downwards. The moving plate 33 pushes the spring 36 and pressure plate 37 to move. The pressure plate 37 moves, causing the rotating shaft 42 and roller 43 to follow. When the roller 43 contacts the film, the drive telescopic rod 32 stops, and then the motor starts, driving the rotating shaft 42 to rotate. The rotating shaft 42 drives the roller 43 to rotate, and the rotating roller 43 contacts the film, pushing it to unfold. This allows the film in the cutting area to be unfolded, avoiding wrinkles that affect the cutting effect. After the film is unfolded, the telescopic rod 32 continues to push the moving plate 33 downward. When the force on the roller 43 exceeds the deformation force of the roller 43, the roller 43 deforms, allowing the bottom of the pressure plate 37 to contact the film. The pressure plate 37 is then restricted from moving further downward. The moving plate 33 moves downward and compresses the spring 36. The reaction force of the spring 36 pushes the pressure plate 37 to compact the film, restricting the film's movement. At the same time, the cutter 34 moves with the moving plate 34. The cutter 34 moves downward and contacts the film to cut it. This restricts the movement of the film on both sides of the cutter 34 during cutting, improving the equipment's efficiency.

[0026] The telescopic rod 32, roller 43 and motor are all existing technologies and will not be described in detail here.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
