Production method of plastic film edge trimming machine

1. This technology relates to the field of film production, in particular to a plastic film edge trimmer.

Background technique:

2. Plastic film is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins for packaging and as a coating layer. Plastic packaging and plastic packaging products account for an increasing share of the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging , quick-frozen food packaging, retort food packaging, fast food packaging, etc. These products have brought great convenience to people's lives. In the production process of plastic films, film winding machines, film trimming machines and other equipment will be used.

3. For related technologies, refer to the Chinese invention patent with the publication number cn109940669a, which discloses a plastic film edge trimming machine, including a base, and a first support column and a second support column are fixedly connected on both sides of the top of the base One side of the top of the column is fixedly connected with a support rod, the left side of the top of the second support column is fixedly connected with a first telescopic rod, the right end of the support rod and the left end of the first telescopic rod are fixedly connected with a limit plate, and the two limit One side of the plate is fixedly connected with a sleeve rod, the surfaces of the two sleeve rods are movably connected with a feeding shaft, a screw rod is rotatably connected between the first support column and the second support column, and both sides of the surface of the screw rod are rotatably connected There is a movable block, the top of the movable block is fixedly connected with a blade, the bottom of one side of the second support column is fixedly connected with a supporting device, and the left side of the supporting device is movably connected with a receiving shaft.

4. For the above-mentioned related technology, the inventor believes that there are the following defects: when it is necessary to cut films of different widths, it is necessary to manually rotate the screw rod to adjust the position of the blade. In the actual adjustment process, the worker needs to rotate the screw rod, and constantly observe the calibration. The position of the blade takes a long time and affects the efficiency of production.
