Problems solved by technology
[0002] In the prior art, when the composite film is wound, the general structural design is relatively complicated. If it is necessary to limit the outer diameter of each roll of the composite film after final winding and cut off the material tape, most of them need to set up certain electronic equipment and cutting. Equipment can be effectively processed, and the use of such a more complicated method will invisibly increase production costs

The invention discloses a cutting device used for a composite film. An automatic cutting assembly is arranged at the tangent position of a material strip feeding cavity and a first containing cavity in the length direction of the first containing cavity, and the automatic cutting assembly comprises a heat isolation plate tightly attached to the inner walls of the material strip feeding cavity andthe first containing cavity, a heating plate tightly attached to the lower bottom face of the heat isolation plate, a cutter arranged on the lower bottom face of the heating plate and an electric control device electrically connected with the heating plate; and the cross section of the cutter is triangular. By means of the cutting device in the structural design, when the diameter of the rolled film reaches the inner diameter of a cavity formed by the first containing cavity and a second containing cavity, a material strip located at the upper mold cavity can make contact with the cutter, heatcarried by the cutter automatically fuses the composite film material strip, and the cutting aim is achieved.
Description
technical field [0001] The invention relates to the technical field of production equipment, in particular to a cutting device for a composite film. Background technique [0002] In the prior art, when the composite film is wound, the general structural design is relatively complicated. If it is necessary to limit the outer diameter of each roll of composite film after final winding and cut off the material tape, it is necessary to set up certain electronic equipment and cutting. Equipment can be effectively processed, and the use of such a more complicated method will invisibly increase production costs. Contents of the invention [0003] The purpose of the present invention is to provide a cutting device with simple structure, low cost and convenient winding and cutting of the composite film. [0004] For reaching this purpose, the present invention adopts following technical scheme: [0005] A cutting device for a composite film, comprising an upper mold cavity, a low...
