Adjustable film slitting device and slitting process thereof

Abstract

The invention discloses an adjustable film slitting device and a slitting process thereof. The adjustable film slitting device comprises a lower base, an upper top plate, supporting columns, lower pressing rollers, slitting rollers and a slitting mechanism. According to the adjustable film slitting device, annular cutting grooves are formed in each slitting roller, floating columns are driven to move downwards by rotating adjusting screw rods, so that cutting cutterheads are driven to move downwards, the cutting cutterheads are located in upper sides of the annular cutting grooves, and thus a film is cut by the cutting cutterheads while being supported by the slitting roller to feed, and since the cutting cutterheads are located in the annular cutting grooves, the cutting cutterheads are not in contact with the slitting rollers, thus avoiding scratches on the slitting rollers, and meeting the high performance requirement for additional attached antiskid materials.

Description

technical field [0001] The invention relates to an adjustable film slitting device and a slitting process thereof. Background technique [0002] As a packaging material, plastic film is widely used in food, medicine, chemical industry 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. It brings great convenience to people's life; when the existing film slitting device is slitting, the film is fed through the lower pressing roller and the slitting roller in turn. In order to ensure the cutting stability and non-deformation of the film, The cutting blade is abutted against the slitting roller to feed the film on the slitting roller, and the film is supported by the slitting roller to make the film more stable and less deformed during cutting, but when the cutting blade and the slitting roller abut , the surface of the cutting roller will be ...

[0002] As a kind of packaging material, plastic film is widely used in food, medicine, chemical industry 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 are all It has brought great convenience to people's life; when the existing film cutting device is cutting, the film is fed through the lower pressure roller and the cutting roller in turn. In order to ensure the cutting stability and non-deformation of the film, Put the cutting blade against the slitting roller to feed the film on the slitting roller. The support of the slitting roller to the film makes the film more stable and not easy to deform when cutting, but when the cutting blade touches the slitting roller , the surface of the cutting roller will be scratched and worn, and after a period of use through the non-slip material, it will also cause peeling due to friction and heat, so it is necessary to change the structure and method of cutting, and at the same time ensure that the cutting position is adjusted Adjustability and flexibility
