Description

Technical Field

[0001] The utility model relates to the technical field of film cutting equipment, in particular to a film material slitting machine for preventing edge warping. Background Art

[0002] Film material slitting machine is a kind of equipment specially used for cutting film materials, which is widely used in packaging, printing, electronics and other industries. Film material slitting machine uses advanced cutting technology to cut roll film into sheets of required size. Its workflow usually includes unwinding, cutting, winding and other steps, and is equipped with tension control, deviation correction control and detection devices to ensure the accuracy and stability of cutting.

[0003] In the laser cutting process, in order to avoid the cutting edge from warping, a fitting cutting mechanism is generally used to support the lower side of the film material, and at the same time, the film material is kept tight through a tensioning mechanism to avoid affecting the cutting quality. However, in order to ensure appropriate tension, the existing equipment uses a tensioning roller mechanism as a third-party support. This mechanism is prone to change the tilt angle of the film material and cannot effectively maintain the horizontal state of the film material to be cut; and the existing cutting support mechanism cannot effectively fit the lower surface of the film material, which is easy to cause the edge to warp during the cutting process and affect the quality.
