Printing machine with translation synchronous moving plates

Abstract

The invention discloses a printing machine with translation synchronous moving plates. The printing machine comprises a machine frame, an embossing roller lifting device and a printing roller liftingdevice. Rectangular lifting grooves are formed in the lower portions of the opposite end faces of a pair of vertical portions of the machine frame correspondingly, lifting supporting blocks matched with the lifting grooves are pivoted to the left end and the right end of a printing roller, lifting supporting blocks are arranged in the lifting grooves in a lifting mode, rectangular inserting limiting grooves are distributed and formed in the middles of the opposite end faces of the pair of vertical portions of the machine frame, connection plates are perpendicularly formed on the exceeding portions of the upper end faces of the pair of lifting supporting blocks, the L-shaped translation synchronous moving plates are horizontally inserted to the upper ends of the connection plates in a left-right mode, the vertical portions of the pair of translation synchronous moving plates are located at the ends away from each other of the pair of translation synchronous moving plates, the vertical portions of the pair of translation synchronous moving plates are matched with the inserting limiting grooves, electromagnets are installed on the lower portions of the side walls away from each otherof the pair of inserting limiting grooves, and the vertical portions of the pair of translation synchronous moving plates are made from metal. Printing quality is ensured, and the service life of theprinting machine is prolonged.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a printing machine with translational counterparts. Background technique [0002] Some paper cutters preliminarily cut the printed paper, then arrange and stack the cut paper, and then further cut the stacked paper, so the work efficiency is low. [0003] The embossing mechanism of the gravure printing machine in the prior art is mainly divided into a direct pressure type and a swing type, wherein the direct pressure type imprinting mechanism mainly pushes the embossing roller to move up and down through two cylinders arranged at both ends of the embossing roller, thereby Realize imprinting and release action. At that time, the embossing mechanism had the following disadvantages: 1. Since the up and down movement of the embossing roller was completed by two different cylinders, it was easy to cause the down movement of the two ends of the embossing roller to be out of...

AI Technical Summary

Problems solved by technology

At that time, the embossing mechanism had the following disadvantages: 1. Since the up and down movement of the embossing roller was completed by two different cylinders, it was easy to cause the down movement of the two ends of the embossing roller to be out of sync, which would affect the embossing of the printing machine. Quality; 2. When the printing machine fails or the power is cut off, the piston rod of the cylinder will drop under the gravity of the embossing roller, and the embossing roller will press on the printing roller. The long-term pressing of the embossing roller will cause the printing tube to bend Even damaged, which seriously affects the normal operation of the printing press
