Description

Technical Field

[0001] The utility model relates to the field of cold cutting machines, in particular to a plastic film cold cutting machine. Background Art

[0002] As we all know, plastic film generally refers to films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, which are used for packaging and as coating layers. Plastic packaging and plastic packaging products occupy an increasingly larger share in 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, steamed food packaging, fast food packaging, etc. These products have brought great convenience to people's lives. Among the many types of plastic films, polyethylene film is widely used as a raw material for packaging bags, food bags and various containers because of its colorless, tasteless, odorless, translucent, non-toxic, insulating and other properties. The cold cutting machine uses a cold cutting tool for cutting, that is, there is no heating between the tool and the material being cut, so the material being cut will not be thermally deformed during the cutting process.

[0003] When the existing cold cutting machine is in use, it lacks a feeding structure and needs manual feeding, which not only wastes manpower but also has low cutting efficiency. Utility Model Content

The plastic film can be clamped and positioned by the clamping assembly, and the plastic film can be driven to move on the processing table 2 by the driving assembly. The plastic film can be cut in the cooling device 3 by the cold cutting assembly. The friction between the plastic film and the clamping plate 7 can be reduced by the guide shaft 8, so that the plastic film can move more smoothly. After the second motor 13 is started, the drive shaft 15 can be rotated, thereby providing a "thrust" to the plastic film. In addition, the positions of the two clamping plates 7 are convenient for adjustment on the processing table 2, and the positions of the two drive shafts 15 are also convenient for lifting, so that the structure can be convenient for cutting plastic films of different sizes, which can reduce the limitations of the structure when used.

[0025] In this structure, the cold cutting assembly includes a first lifter 4 and a first motor 5. The first lifter 4 is fixed at the upper end of the cooling device 3. The first motor 5 is located inside the cooling device 3. The output end of the first motor 5 is provided with a cooling knife 6 for cutting the plastic film. The output end of the first lifter 4 passes through the cooling device 3 and is connected to the first lifter 4. Starting the first motor 5 can make the cooling knife 6 rotate, and starting the first lifter 4 can make the cooling knife 6 descend, thereby cutting the plastic film.

[0026] When it is necessary to clamp plastic films of different sizes, the position of the clamping plate 7 needs to be temporarily adjusted. Two thrusters 9 are symmetrically arranged at the front end of the processing table 2. The output ends of the thrusters 9 are connected to the clamping plate 7. Starting the thrusters 9 can move the clamping plate 7, which facilitates the adjustment of the position of the clamping plate 7.

A plurality of slide grooves 10 are symmetrically arranged at the front end of the processing table 2. A slider that cooperates with the slide groove 10 is arranged at the lower end of the clamping plate 7. When the clamping plate 7 moves, the slider will slide in the slide groove 10, thereby providing a guide structure between the clamping plate 7 and the processing table 2, and improving the stability of the clamping plate 7 when it moves.

[0029] In this structure, the propeller 9 is a pneumatic cylinder, the first lifter 4 and the second lifter 14 are hydraulic cylinders, and the first motor 5 and the second motor 13 are both servo motors.
