Technical Field

[0001] The utility model relates to the technical field of slitting devices, in particular to a stretch film slitting device which is easy to position. Background Art

[0002] Film is a transparent and soft sheet. Its raw materials are mostly plastic, rubber and adhesive. First, multiple materials are mixed and dissolved together. After the material particles are homogenized, the material is discharged and pressed and shaped by relative rollers to squeeze the material into a thin film.

[0003] In order to facilitate the transportation and carrying of the film, it needs to be wrapped and stored on a rod in the later stage of its manufacture. If it is to be taken out and used, a slitting device is used to cut the film wrapped on the surface of the rod to avoid damage to the film due to the cut. However, previous film cutting devices all use a fixed structure to restrict the film rod, which is quite inconvenient to replace when the film is used up.

[0004] Now, a new type of stretch film slitting device that is easy to position is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a stretch film slitting device that is easy to position, so as to solve the problem of inconvenience in replacing film materials raised in the above background technology.

[0015] (1) By wrapping a membrane body around the outside of the sleeve, first press down the ring and guide the sliding sleeve to move down along the guide rod. At this time, the support spring is squeezed and shortened, and the sleeve with the membrane body is placed in the box body. When the top of the sleeve is sleeved on the outside of the fixed rod, loosen the ring and allow the spring to support the sliding sleeve and sleeve it on the bottom of the sleeve. The sleeve is sleeved and limited at the upper and lower parts, which does not affect the rotation of the sleeve by the motor and can also prevent the sleeve and the membrane body from separating from the box body;

If no cutting is required, the blade connected to the shift block is guided to be embedded in a sleeve of a groove and stay there to avoid unnecessary damage to the membrane;

[0017] (3) By fixing a support block at the center of the side of the cover, the support block will fit into the docking block at the moment the cover is closed, guiding the pressure block to embed into the storage groove. At this time, the guide rod will slide out of the slot along the hole, and the second spring will also be squeezed and apply reverse pressure, pushing the pressure block toward the docking block and squeezing and fixing the center of the membrane body to prevent the membrane body from moving back and forth along the through groove of the box body.
