Description

Technical Field

[0001] The utility model belongs to the technical field of pre-coating film slitting, in particular to a slitting machine with adjustable width for pre-coating film. Background Art

[0002] The pre-coated film is composed of a base material and an adhesive layer. The base material is usually a polyester film and a biaxially oriented polypropylene film. Compared with the film produced by the transmission coating and laminating process, the pre-coated film is more environmentally friendly and convenient.

[0003] According to the patent authorization publication number CN219669725U, a PE heat shrink film slitting mechanism that is easy to adjust the slitting width is disclosed, including a winding module and a slitting module, the winding module includes a mounting base plate, a plurality of rectangular plates connected to the top of the mounting base plate, a first rotating shaft installed between two rectangular plates, a second rotating shaft movably connected between the two rectangular plates, and a motor connected to the front end of the second rotating shaft, and the slitting module includes two support plates connected to the top of the mounting base plate.

[0004] The above prior art often has the following problems when used:

[0005] When the above device is used, the blade is moved and fixed by manually adjusting the bolt, which is time-consuming and labor-intensive, prone to errors and has low production efficiency;

[0006] When the above device is in use, no corresponding transmission device is arranged between the first rotating shaft and the second rotating shaft. As a result, when the motor drives the second rotating shaft to rotate, the first rotating shaft and the second rotating shaft are connected through the membrane, so that the first rotating shaft rotates with the second rotating shaft. However, under this traction force, the tension of the membrane itself can be easily destroyed, resulting in damage to the quality of the membrane and affecting production efficiency.
