Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to an automatic plate-changing printing device. Background Art

[0002] A printing press is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding (including folding). Its principle is to first make the text or image to be printed into a printing plate, install it on the printing press, and then apply ink to the place where the text and image are on the printing plate manually or by the printing press, and then directly or indirectly transfer it to paper or other substrates.

[0003] The existing printing device needs to replace the printing plate after printing is completed to carry out the next printing operation. However, the general printing device needs to stop the printing machine when replacing the printing plate, and then replace the printing plate. This replacement method reduces the printing efficiency of the printing device, and during the installation of the printing plate, it is necessary to twist multiple bolts to disassemble and assemble the printing plate. The installation process is cumbersome, which greatly reduces the work efficiency of the staff. Utility Model Content

[0038] Working principle:

[0039] The staff connects the printing plate body 5 and the connecting seat 403 to one end of the connecting plate 304, and then rotates the driving handle to drive the threaded column 406 to rotate.

When the printing plate body 5 needs to be replaced, the staff starts the electric push rod 306 to make the top printing plate body 5 detach from the inside of the printing slot 2, and then starts the driving motor 307 to drive the driving shaft and the rotating shaft 305 to rotate. The rotating shaft 305 drives the printing plate body 5 at one end to rotate through the connecting plate 304, so that the printing plate body 5 to be used is rotated to the bottom of the printing slot 2, and then the electric push rod 30 6 is retracted, so that the printing plate body 5 moves to the inside of the printing groove 2 and is in a working state. When the electric push rod 306 is retracted to drive the support plate to move, the support plate drives the tooth plate 11 on one side to move, and the tooth plate 11 makes the tooth plate 11 on the other side move in the opposite direction through the gear 12 meshing on one side. The tooth plate 11 drives the top cross plate and the connecting piece to slide on the outer surface of the column 6, and the connecting piece drives the supporting frame 7 to move, so that the conveying roller 8 inside the bearing frame 7 is close to the upper surface of the printed object, and then the servo motor 10 is started to drive the driving shaft and the pulley to rotate, so that the roller shaft below drives the meshing wheel 9 and the meshing tooth chain on the outer surface to rotate synchronously, so that the several roller shafts and the meshing wheel 9 on both sides rotate synchronously, and the roller shaft drives the conveying roller 8 on the outer surface to rotate synchronously, so as to move the printed object and perform continuous printing operations.
