Electrothermal film intaglio printing equipment

Abstract

The invention discloses electrothermal film intaglio printing equipment. The electrothermal film intaglio printing equipment comprises a conveying deviation rectifying device, a carbon paste roll printing device, a first drying channel device, a silver paste roll printing device, a second drying channel device, a third drying channel device and a rolling shaft transmission system. The conveying deviation rectifying device is used for loading and conveying a photomask, and the carbon paste roll printing device, the first drying channel device, the silver paste roll printing device, the second drying channel device and the third drying channel device are sequentially arranged on a transmission path of the rolling shaft transmission system. The rolling shaft transmission system comprises a first water cooling roll arranged close to an outlet of the first drying channel device and a second water cooling roll arranged close to the second drying channel device. According to the electrothermal film intaglio printing equipment, the production efficiency, the printing effect and the product percent of pass can be improved.

Description

technical field [0001] The invention relates to the technical field of electric heating film, in particular to an electric heating film gravure printing equipment. Background technique [0002] The existing electrothermal film gravure printing equipment adopts one-time printing process, without feeding device and cooling design after drying, resulting in low production efficiency, poor printing effect and low pass rate. Moreover, in the latest electrothermal film gravure printing equipment, after the electrothermal film is printed with the corresponding slurry layer and is initially dried through its corresponding drying channel, it is generally directly printed on another slurry layer or It is the next level of drying operation. However, since the electrical characteristics of the slurry layer are not stable after the initial drying of the electrothermal film, if the next step of slurry printing or next-level drying operation is carried out directly, it will easily cause e...

Problems solved by technology

However, since the electrical characteristics of the slurry layer are not stable after the initial drying of the electrothermal film, if the next step of slurry printing or next-level drying operation is carried out directly, it will easily cause electrical failure of the electrothermal film, which restricts The qualified rate of product production
