Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, and more specifically, to a printing roller for a printing machine. Background Art

[0002] The printing press cylinder (roller) is a core component of printing machinery. Its surface finish and geometric accuracy have a significant impact on the quality of printed products. Especially when printing fine prints, the slightest error can reduce the overall effect of the print, causing blurring or distortion on both sides of the printed product. The acidic inks, alcohol, water, and other chemical raw materials used in the printing process can corrode the sides of the printing press cylinder (roller), often causing local collapse and spots on the inking and plate cylinders (rollers). Chrome-plated cylinders (rollers) are often dented by foreign matter. Furthermore, long-term and excessive use can cause wear and failure of printing equipment.

[0003] During the printing process, the existing equipment requires different molds for each batch of printing, resulting in different sizes of printing rollers each time. Therefore, the discharge mechanism needs to be adjustable to meet long-term use. Therefore, a printing roller for a printing press has been introduced to solve this problem. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a printing roller for a printing machine. The technical problem to be solved by the present invention is: since the molds required for printing in each batch are different, the size of the printing roller used each time is also different, so the discharge mechanism needs to be adjustable to meet the problem of long-term use.

[0005] To achieve the above object, the utility model provides the following technical solution: a printing cylinder for a printing press, comprising a bracket assembly, a feeding assembly is provided inside the bracket assembly, and a moving assembly is provided at the bottom of the bracket assembly;

[0006] The bracket assembly includes a support frame, screw holes are opened on both sides of the top of the support frame, multiple locking grooves are opened on the top of the support frame, both sides of the bottom of the support frame are fixedly connected to the movable frame, sliding grooves are opened on the inner wall of the movable frame, multiple limit bars are fixedly connected to the bottom of the support frame, multiple lock holes are opened on the surface of the limit bars, a first rotating opening is opened through the surface of the movable frame, printing rollers are provided on the inner sides of the multiple movable frames, both ends of the printing rollers are fixedly connected to the first rotating column, recovery frames are provided on the inner sides of the multiple limit bars, locking blocks are fixedly connected on both sides of the recovery frame, and a discharge plate is fixedly connected to the outer surface of the recovery frame.

[0013] Technical effects and advantages of this utility model:

[0014] 1. The utility model is provided with a bracket assembly and a feeding assembly.
