Embossing device for gravure printing machine

Abstract

The invention provides an embossing device for a gravure printing machine, which includes a frame, a cylinder is connected to the beam plate of the frame, and a movable shaft is connected to the power output end of the cylinder, and a press is arranged on the movable shaft. An embossing roller installation shaft, an embossing roller is arranged on the embossing roller installation shaft, and guide tubes that limit the running track of the movable shaft are respectively provided on the two vertical support plates, and on the side walls of the guide tubes An open guide rail groove is provided along the axial direction of the guide tube, and a slider sliding along the axial direction of the guide tube is arranged inside the guide tube, and the two ends of the movable shaft respectively pass through the open guide rail groove and the The sliders are connected. The invention is used for the embossing device of the gravure printing machine, which can ensure the synchronization of the movement of both ends of the embossing roller, and further improve the embossing quality of the gravure printing machine.

Description

technical field [0001] The invention belongs to the technical field of printing machines, in particular to an embossing device for gravure printing machines. Background technique [0002] The embossing devices used in gravure printing machines in the prior art are mainly divided into two types: direct pressure type and swing type. The direct pressure type imprinting device mainly pushes the embossing roller through two cylinders arranged at both ends of the embossing roller. Up and down movement for imprinting and release. However, the disadvantage of this embossing device is: since the up and down movement of the embossing roller is completed by two different cylinders, it is easy to cause the down movement of the two ends of the embossing roller to be out of sync, which in turn affects the embossing of the gravure printing machine. print quality. Contents of the invention [0003] The invention provides an embossing device for a gravure printing machine with synchronou...
