Description

Technical Field

[0001] The utility model relates to the technical field of film tearing processing, in particular to a film tearing mechanism for a film material. Background Technique

[0002] When performing a film tearing operation on some products with a film attached to the surface, a film tearing device is required. Nowadays, most film tearing devices stick up the film through the adhesiveness of the tape, and wind up the film and the tape together through the transmission of the transmission table and the winding of the winding roller.

[0003] Nowadays, when stabilizing the tape in the film tearing mechanism, most of them wind the tape roll on the outer wall of the tape roller and limit the tape roll through the limit block. When replacing the tape roll, first, the limit block needs to be disassembled, and then the used tape roll is taken out, making the replacement of the tape roll relatively cumbersome. Secondly, since the film and the used tape are wound around the outer wall of the winding roller after the film is wound, it is relatively laborious to take out the wound film.

[0012] In the present utility model, when placing the tape roll, the tape roll is sleeved on the outer wall of the tape placing roller. Rotating the rotating block drives the rotating plate to rotate. The rotation of the rotating plate causes the arc-shaped block to move away from the inner wall of the arc-shaped groove. At the same time, when the rotating plate rotates, the outer wall of the rotating plate presses against the arc-shaped block. The arc-shaped block is pressed to drive the extension plate to move. The movement of the extension plate drives the moving block to move, and at the same time stretches the connecting spring. The movement of the moving block drives the tip of the pointed block to move towards the inner wall of the tape roll, thereby limiting the tape roll. When disassembling the used tape roll, rotate the rotating block to make the rotating plate rotate. When the arc-shaped groove opened on the rotating plate rotates to one side of the arc-shaped block, the connecting spring resets to drive the moving block and the pointed block to move away from the inner wall of the tape roll. The extension plate drives the arc-shaped block to re-enter the inside of the arc-shaped groove, facilitating the replacement of the tape roll by the staff and increasing the stability of the tape roll.

[0013] In the present utility model, during the film tearing operation, the adhesive surface of the tape roll is located below, and one end of the tape is attached to the outer wall of the plastic sleeve. By turning on the motor drive frame to drive the rotating roller to rotate, the rotating roller rotates to drive the winding roller, the plastic sleeve and the plastic positioning slider to rotate. Then, the tape is guided by the guiding roller, and the product is limited by the limiting roller. The film is torn off by the adhesiveness of the tape. The torn film and tape are wound around the outer wall of the plastic sleeve by the continuous rotation of the winding roller. When the film needs to be collected, turn the motor drive frame to make the rotating roller flip, pull one end of the plastic sleeve, so that the plastic sleeve moves on the outer wall of the winding roller through the plastic positioning slider, and then the plastic sleeve and the winding roller are separated. The film is taken off with the plastic sleeve. A new plastic sleeve is sleeved on the outer wall of the winding roller again through the plastic positioning slider, facilitating the staff to remove the used tape and the torn film. The plastic sleeve and the plastic positioning slider can be recycled with the film and tape. Description of the Drawings

[0030] The usage method and advantages of the present utility model: When this film tearing mechanism for film materials is working, the working process is as follows:

[0031] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, when placing the tape roll, the tape roll is sleeved on the outer wall of the tape placing roller 203. Rotating the rotating block 206 drives the rotating plate 205 to rotate. The rotation of the rotating plate 205 causes the arc-shaped block 305 to move away from the inner wall of the arc-shaped groove. At the same time, when the rotating plate 205 rotates, the outer wall of the rotating plate 205 presses against the arc-shaped block 305. The arc-shaped block 305 is driven by the extrusion to drive the extension plate 304 to move. The movement of the extension plate 304 drives the moving block 302 to move, and at the same time stretches the connecting spring 301. The movement of the moving block 302 drives the tip of the pointed block 303 to move towards the inner wall of the tape roll, thereby limiting the tape roll. When disassembling the used tape roll, rotate the rotating block 206 to make the rotating plate 205 rotate. When the arc-shaped groove opened on the rotating plate 205 rotates to one side of the arc-shaped block 305, the connecting spring 301 drives the moving block 302 and the pointed block 303 to move away from the inner wall of the tape roll through resetting. The arc-shaped block 305 is driven by the extension plate 304 to re-enter the inside of the arc-shaped groove. During the film tearing operation, the adhesive surface of the tape roll is located below, and one end of the tape is attached to the outer wall of the plastic sleeve 502. By turning on the motor drive frame 402 to drive the rotating roller 403 to rotate, the rotating roller 403 drives the winding roller 501, the plastic sleeve 502, and the plastic positioning slider 503 to rotate. Then, the tape is guided by the guiding roller 103, and the product is limited by the limiting roller 104. The film is torn off by the adhesiveness of the tape. The torn film and tape are wound around the outer wall of the plastic sleeve 502 by the continuous rotation of the winding roller 501. When the film needs to be collected, rotate the motor drive frame 402 to flip the rotating roller 403, and pull one end of the plastic sleeve 502, so that the plastic sleeve 502 moves on the outer wall of the winding roller 501 through the plastic positioning slider 503, thereby separating the plastic sleeve 502 from the winding roller 501. The film is removed along with the plastic sleeve 502, and a new plastic sleeve 502 is sleeved on the outer wall of the winding roller 501 again through the plastic positioning slider 503.
