Abstract

The invention relates to the field of film processing and manufacturing, in particular to a film die-cutting machine for reducing edge damage. The technical problems that when an existing die cutting machine conducts die cutting on a thin film, the edge of a thin film piece can be damaged, and sheet separation is difficult to achieve are solved. According to the technical scheme, the film die-cutting machine for reducing edge damage comprises a mounting plate, a film edge processing system, a die-cutting system and the like; the upper side of the front of the mounting plate is connected with a die-cutting system; the front part of the mounting plate is connected with a film edge treatment system. A traditional film die-cutting mode is abandoned, the contour line with the length larger than the specification length is formed on the opposite side of the die-cutting film piece in a die-cutting mode firstly, then the two remaining edges of the film piece are subjected to die-cutting, meanwhile, upward tensile force is applied to the lower portion of the die-cutting position of the film piece, the edges of the film piece are prevented from being wound when being broken, and the film piece is prevented from being broken. Meanwhile, the film sheet is separated in a lower suction mode, edge wrinkles of the film sheet caused by friction force between the cutting blade and the film belt are avoided, and edge damage of the film sheet is reduced.

Description

technical field [0001] The invention relates to the field of film processing and manufacturing, in particular to a film die-cutting machine for reducing edge damage. Background technique [0002] Die-cutting machine is also called beer machine, cutting machine, CNC stamping machine, mainly used for die-cutting of some corresponding non-metallic materials, stickers, EVA, double-sided tape, electronics, mobile phone rubber pads, etc. [0003] Existing die-cutting machines use cutting tools to cut out the rough outline of the polyester film, and then trim the outline a second time. This conventional method is difficult to completely fall off the polyester film sheet. At the same time, cutting applies a tension force in one direction to the polyester film tape, which easily causes the edge of the sheet to curl when it breaks. During the cutting process, the friction between the cutting blade and the film tape causes the edge of the film to wrinkle. The shape of the sheet is irr...
