[0002] At present, the common heat insulation pad on the market is a regular cuboid structure, and the packaging film material used is also a regular quadrilateral shape, the size of the regular film material is larger than that of the heat insulation pad, so the film material cutter is needed for slitting, but since the film material cutter is also of the same structure as the common heat insulation pad, the film material cut is also of a regular quadrilateral shape, and the use of regular film material for packaging the heat insulation pad product with a boss and a cut corner structure has the following defects: 1. Excessive empty space or film material wrinkle accumulation at the cut corner position; 2. The film material is difficult to paste with the core material at the step, and the hollow drum phenomenon occurs. The use of the conventional film material cutter to cut the film material cannot meet the cutting requirement of the special-shaped structure heat insulation pad, but if the shape of the film material is changed according to the special-shaped structure heat insulation pad, the manufacturing cost of the heat insulation pad will be greatly increased.
