TECHNICAL FIELD
[0001] The utility model relates to a printing machine, concretely relates to a high stability printing unit. BACKGROUND
[0002] The printing machine is a kind of equipment for printing processing to substrate to obtain required pattern. The structure of printing unit mainly includes ink supply assembly, plate roller and compression roller, and ink is transferred to plate roller by ink supply assembly during work, and plate roller and compression roller cooperate to print and process the substrate passing through. The defects of traditional printing equipment are as follows: 1. The traditional transmission mode is that compression roller is linked with plate roller, so plate roller stops, and compression roller also stops when plate roller rotates, compression roller also rotates. According to different printing requirements, two processes are divided, the first process is that plate roller is variable speed, and compression roller also stops when plate roller stops, and substrate is driven by traction roller, so substrate does not stop, and substrate and compression roller are in " one static one motion " state, and then friction is generated, and substrate is damaged. The second process is that plate roller is constant speed, and substrate is variable speed, and in this process, plate roller always drives compression roller to rotate, but substrate is variable speed with traction roller, and there is stop state, and then friction is generated between substrate and compression roller, and substrate is damaged; 2. The traction assembly of substrate is usually arranged close to winding mechanism, and in actual use process, because the distance between substrate and traction assembly is far when substrate passes through printing assembly, the position precision of substrate traction conveying to printing unit is difficult to guarantee, and the precision of subsequent printing is influenced.
