Technical Field

[0001] The utility model relates to the technical field of coil material processing, in particular to a film-tearing and feeding device for converting sheet material into coil material. Background Art

[0002] Sheet to roll conversion refers to the process of converting sheet materials into roll materials. The film tearing and feeding device for sheet to roll conversion is an automated equipment, which is mainly used to convert sheet materials into roll materials, and in this process, the original protective film is torn off and a new protective film is attached.

[0003] When the roll material is not effectively pressurized during the film-tearing and feeding process of sheet material to roll material, the winding tightness of the converted roll material may be affected. Because the roll material does not receive proper pressure during the winding process, the material may become loose, resulting in loose winding, increasing the gaps inside the roll material, and affecting the flatness and performance of the material. Therefore, a film-tearing and feeding device for converting sheet material to roll material is proposed to solve the above problems. Utility Model Content

The bracket 21 is arranged on the outside of the coil machine body 1, and the coil roller 22 is connected to the inside of the bracket 21 for winding the sheet material into a coil. The slitting knife 23 is arranged at an angle on the outside of the bracket 21 for tearing the film of the sheet material. The sheet material is placed on the coil machine body 1 and is ready for rolling and tearing the film. The slitting knife 23 is arranged at an angle on the outside of the bracket 21 for tearing the film of the sheet material, that is, peeling off the original protective film. The sheet material after tearing the film is sent to the coil roller 22 and begins to be wound into a coil.

[0023] The coil assembly 2 also includes a support frame 24 horizontally arranged on the outside of the bracket 21. The inner walls of the front and rear sides of the support frame 24 are provided with sliding grooves 25, and the inside of the two sliding grooves 25 are provided with return springs 26. The two return springs 26 are fixed with sliding rollers 27 at one end away from the inner wall of the sliding groove 25. The outer side of the sliding roller 27 is rotatably provided with a pressure roller 28 to apply pressure to the coil to keep the coil even and tight. As the number of layers of the coil increases, the outer side of the coil will contact the pressure roller 28 and push the pressure roller 28 to move outward. The pressure roller 28 is connected to the return spring 26. In the process of being pushed outward, the return spring 26 will pull the pressure roller 28 inward. The pressure roller 28 applies a certain pressure to the coil to ensure that the coil can be wound evenly and tightly.

[0024] In this embodiment, the length of the pressure roller 28 is greater than that of the winding roller 22, so as to apply uniform pressure to the coiled material. The outer side of the pressure roller 28 is covered with a silicone sleeve to reduce the wear on the coiled material. The front and rear ends of the sliding roller 27 are fixed with synchronization frames, and the sliding roller 27 is connected to the two reset springs 26 through two synchronization frames respectively. A U-shaped groove is provided inside the bracket 21 for the winding roller 22 to be placed, so as to facilitate the taking and placing of the winding roller 22 with the coiled material.

[0025] It should be noted that the length of the pressure roller 28 is greater than that of the winding roller 22 to ensure uniform pressure on the entire width of the coil. The outer side of the pressure roller 28 is covered with a silicone sleeve to reduce wear on the coil and protect the surface of the material. Synchronous frames are fixed to the front and rear ends of the sliding roller 27. The sliding roller 27 is connected to two return springs 26 through a synchronization frame to ensure the stability and synchronous movement of the pressure roller 28. The sheet material continues to be wound on the winding roller 22 to form a rolled material. A U-shaped groove is provided inside the bracket 21 to facilitate the taking and placing of the winding roller 22 with the coiled material. The coiled material after film tearing and winding is collected and output as a finished product.

[0026] The working principle of the above embodiment is:

[0027] The sheet material is placed on the coiling machine body 1 and is ready for rolling and tearing. The slitting knife 23 is tilted and set on the outside of the bracket 21 to tear the film of the sheet material, that is, to peel off the original protective film. The sheet material after tearing the film is sent to the coiling roller 22 and begins to be wound into a coil. As the number of coil layers increases, the outside of the coil will contact the pressure roller 28 and push the pressure roller 28 to move outward. The pressure roller 28 is connected to the return spring 26. In the process of being pushed outward, the return spring 26 will pull the pressure roller 28 inward. The pressure roller 28 applies a certain pressure to the coil to ensure that the coil can be evenly and tightly wound. Winding, the length of the pressure roller 28 is greater than that of the winding roller 22 to ensure uniform pressure on the entire width of the coil. The outer side of the pressure roller 28 is covered with a silicone sleeve to reduce wear on the coil and protect the surface of the material. Synchronous frames are fixed to the front and rear ends of the sliding roller 27. The sliding roller 27 is connected to two return springs 26 through a synchronization frame to ensure the stability and synchronous movement of the pressure roller 28. The sheet continues to be wound on the winding roller 22 to form a rolled material. A U-shaped groove is provided inside the bracket 21 to facilitate the taking and placing of the coil roller 22 with the coiled material. The coiled material after film tearing and winding is collected and output as a finished product.
