Problems solved by technology
In the existing technology, only cold lamination can be performed on intermittent rotary printing machines, that is, glue is needed to bond the paper and film, and the conditions are limited; if hot lamination is used, the intermittent rotary paper feeding method will be difficult It will cause local overheating of the film, resulting in overheating marks on the surface of the film, and the quality of the coating will be poor

The intermittent rotary hot laminating printing machine is characterized in that an unwinding component, an intermittent rotary printing component, a hot laminating component and a winding component are arranged front and back, the hot laminating component comprises a hot laminating roller and a bottom pressing roller which are arranged up and down, and the hot laminating roller is in transmission connection with a laminating roller motor; a paper inlet floating roller and a paper outlet floating roller are respectively arranged at the paper inlet end and the paper outlet end of the hot laminating component; during working, the paper feeding floating roller and the paper discharging floating roller are driven by a servo motor to synchronously act in the front-back direction, so that intermittent rotary paper feeding entering the hot laminating component is converted into full rotary paper feeding, and meanwhile, full rotary paper feeding leaving the hot laminating component is converted into intermittent rotary paper feeding again. On the basis of the intermittent rotary press, the hot laminating function is added, the hot laminating quality is guaranteed, meanwhile, the multi-functional configuration of front and back gold stamping, front and back silk printing, flat circle die cutting and the like is achieved, the selectivity is high, and the multi-functional rotary press can better adapt to printing production of high-grade printed matter.
Description
technical field [0001] The invention relates to the technical field of printing equipment, in particular to an intermittent rotary printing machine. Background technique [0002] Intermittent rotary printing machines are widely used in label printing and PS plate printing. For some high-end printed products (such as red wine labels), the surface of the paper needs to be coated after printing, that is, a layer of transparent film is attached to the surface of the printed and bronzing paper. The film is then printed and stamped on the surface of the film, and finally wound up. In the existing technology, only cold lamination can be performed on intermittent rotary printing machines, that is, glue is needed to bond the paper and film, and the conditions are limited; if hot lamination is used, the intermittent rotary paper feeding method will be difficult This will lead to local overheating of the film, causing overheating marks on the surface of the film, and the quality of th...
