Double-face printing device for plastic thin film

Abstract

The invention relates to the technical field of plastic thin film printing, in particular to a double-face printing device for a plastic thin film. The double-printing device comprises an unrolling mechanism, a pre-printing room, the plastic thin film, pressing rolls, a double-face printing room, a base, a cooling mechanism and a rolling mechanism, the unrolling mechanism is fixed to the end of the base, and the rolled plastic thin film is placed inside the unrolling mechanism; the plastic thin film penetrates through the pre-printing room, and the two parallel pressing rolls are fixed to theends of the pre-printing room; the double-face printing room is fixed to the top of the base, and the interior of the double-face printing room penetrates through the plastic film; the plastic thin film passes through the cooling mechanism, and the end of the plastic thin film is connected with the rolling mechanism. The double-face printing device is flexible to operate and can cool the printed plastic thin film, avoids rubbing dirt and sticking dirt, and improves printing quality.

Description

technical field [0001] The invention relates to the technical field of plastic film printing, in particular to a plastic film double-sided printing device. Background technique [0002] Plastic film is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, used for packaging and as a coating layer; plastic packaging and plastic packaging products account for an increasing share of the market The larger, especially the composite plastic flexible packaging, has been 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, cooking food packaging, fast food packaging, etc., these Products have brought great convenience to people's lives.

Problems solved by technology

[0003] The plastic film prints patterns on its surface by printing, so that it can be used in various fields. The existing printing equipment is directly wound into the winding shaft after printing. Due to the high temperature of printing, the pattern after printing It is easy to be transferred to other positions, causing dirt and stickiness; it is not flexible enough when unwinding and rewinding at the same time
