Abstract

The invention discloses a PVC plastic film thermal cutting device for packaging, which comprises a side frame, an unwinding roller is arranged on one side of the side frame, a limit ring is arranged on the outer end of the unwinding roller, and a first conveying roller is arranged on the front of the side frame , the outer end of the first conveying roller is provided with a first driven wheel, the front of the side frame is provided with a second conveying roller, and the outer end of the second conveying roller is provided with a second driven wheel; the back of the side frame is provided with a drive motor, driving The front part of the motor is provided with a drive shaft, the drive shaft passes through the side frame, the end of the drive shaft is provided with a drive wheel, and the drive wheel is connected to the first driven wheel through a belt; the front of the side frame is provided with a driven roller, and the driven roller The outer end of the side frame is provided with a drive wheel, and the other side of the side frame is provided with a cutting table. The lift of the lifting frame of the present invention drives the cutting block to realize vertical lifting adjustment, the electric heating knife at the lower part of the cutting block is energized and generates heat, and the cutting block can quickly cut the PVC plastic film on the cutting table through the electric heating knife .

Description

technical field [0001] The invention relates to a cutting device, in particular to a thermal cutting device for PVC plastic film for packaging. Background technique [0002] Biaxially oriented polypropylene film is made by co-extruding polypropylene particles to form a sheet, and then stretching in both vertical and horizontal directions. Due to the orientation of the stretched molecules, this film has good physical stability, mechanical strength, air tightness, high transparency and gloss, and is tough and wear-resistant. It is currently the most widely used printing film, and the general thickness is 20~ 40μm, the most widely used is 20μm. The main disadvantage of biaxially oriented polypropylene film is poor heat sealability, so it is generally used as the outer film of composite film. For example, after compounding with polyethylene film, the moisture resistance, transparency, strength, stiffness and printability are all ideal. It is suitable for Hold dry food. Since ...
