[0002] PE protective film is a widely used plastic film material, mainly made of polyethylene resin, with good flexibility and certain puncture resistance. The protective film needs to be cut using a cutting device during the production process. The current cutting device uses a reel to spread the protective film flat on the table, and then uses a cutting tool to cut it. However, most of the cutting devices do not have a positioning structure, and it is difficult to position the protective film during cutting, which leads to problems such as uneven cutting or non-parallel edges of the protective film, thereby affecting the overall quality of the product. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] like Figure 1-4 As shown, the utility model provides a technical solution: a PE protective film cutting device that is easy to disassemble, including a body 1, a fixed block 2 is connected to the body 1, a motor 3 and a cutting tool 4 are arranged on the body 1, one end of the motor 3 is connected to an anti-slip belt 5, the fixed block 2 is connected to a workbench 6, the fixed block 2 is externally connected to a fixed rod 7, the fixed block 2 is internally rotatably connected to a threaded rod 16, and the threaded rod 16 is externally threadedly connected to a movable plate 12;

[0020] The motor 3 is connected to the cutting tool 4 through the anti-slip belt 5, and one end of the fixed rod 7 is connected to the fixed plate 8, and the fixed rod 7 is slidably connected to the card plate 9, and the card plate 9 is rotatably connected to the roller 10. By setting the card plate 9, when the roller 10 is clamped in the card plate 9, when the protective film on the surface of the roller 10 is pulled, the roller 10 will rotate in the card plate 9, so that the card plate 9 plays a certain auxiliary role in the rotation of the roller 10, avoiding the roller 10 from bumping when rotating;

[0021] The fixing rod 7 is connected with a spring 11, and the fixing plate 8 is connected to the card plate 9 through the spring 11. By setting the spring 11, when the card plate 9 is affected by the thrust or tension, it will move on the surface of the fixing rod 7, and the card plate 9 will drive the spring 11 to deform when moving, so that the spring 11 plays a certain supporting role for the movement of the card plate 9. When the card plate 9 loses resistance, it will be reset by the spring 11;

[0022] A guide rod 18 is connected inside the fixed block 2, and a movable plate 13 is slidably connected outside the guide rod 18. A spring 19 is connected to the outer sleeve of the guide rod 18. One side of the movable plate 13 is connected to a limit plate 14, and one side of the movable plate 12 is connected to a limit plate 15. A rotating rod 20 is rotatably connected inside the fixed block 2, and a roller 21 is connected outside the rotating rod 20. A connecting belt 22 is rotatably connected outside the roller 21, and one end of the threaded rod 16 is connected to a motor 17.

[0023] By providing the guide rod 18, when the movable plate 13 is affected by the tension, the movable plate 13 will move on the surface of the guide rod 18, so that the guide rod 18 plays a certain guiding role in the movement of the movable plate 13, thereby preventing the movable plate 13 from getting stuck during movement;

[0024] The second moving plate 13 is connected to the fixed block 2 through the second spring 19, the second motor 17 is connected to one side of the fixed block 2, one end of the connecting belt 22 is connected to the first moving plate 12, and the other end of the connecting belt 22 is connected to the second moving plate 13;

[0025] By setting the connecting belt 22, when the moving plate 12 is subjected to thrust, the connecting belt 22 will be driven to rotate on the surface of the roller 21, and the moving plate 2 13 will move with the rotation of the connecting belt 22, so that the moving plate 1 12 and the moving plate 2 13 can achieve the function of synchronous movement, avoiding the moving plate 1 12 and the moving plate 2 13 from being misaligned when moving.

[0026] The working principle of the utility model is:

[0027] When the cutting device is in use, a thrust can be applied to the card plate 9. When the card plate 9 moves on the surface of the fixed rod 7, the spring 11 is deformed, and then the roller 10 wrapped with the protective film is placed on the position of the card plate 9. When the card plate 9 is released, it is reset by the action of the spring 11. After the reset, the card plate 9 is clamped with the roller 10, and then the protective film in the roller 10 is placed above the workbench 6.

[0028] When the threaded rod 16 is driven to rotate by the motor 2 17, the movable plate 12 will move on the surface of the threaded rod 16. Since the movable plate 12 is connected to the movable plate 2 13 through the connecting belt 22, the movable plate 12 will drive the connecting belt 22 to rotate on the surface of the roller 21 when it moves, and the movable plate 2 13 will move in the guide rod 18 as the connecting belt 22 pulls. The movable plate 2 13 will drive the spring 2 19 to deform when it moves. The limit plate 14 and the limit plate 2 15 can position the protective film after relative movement. When the movable plate 12 is restored, the movable plate 2 13 will be reset by the spring 2 19, and then the cutting tool 4 will be driven to rotate by the motor 1 3 and the anti-slip belt 5, and the cutting tool 4 will cut the protective film in the workbench 6.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0030] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
