Description

Technical Field

[0001] The utility model relates to the technical field of printing rollers, in particular to a printing plate-making roller. Background Art

[0002] Printing plate making rollers are generally used for plate making. Copper is plated on the surface of the roller, and patterns and texts are engraved by a gravure electronic engraving machine, and then a layer of chrome is plated. In order to facilitate the cleaning of residues on the roller surface, the prior art discloses an anti-corrosion printing plate making roller, with announcement number CN218593920U, comprising a support assembly, a roller assembly and a cleaning assembly. The support assembly comprises a U-shaped plate, side plates fixed on the upper sides of both ends of the U-shaped plate, and a fixed plate vertically fixed to one end of the two side plates. Through holes are provided on the two side plates, grooves are provided on the inner side walls of the two side plates, and a placement groove is provided in the middle part of the outer side of the fixed plate. The roller assembly comprises a rotating shaft with an outer wall fitted in the through hole and a roller body fixed on the outer side of the middle part of the rotating shaft. The cleaning assembly comprises a motor fixed in the placement groove, a lead screw fixed at the output end of the motor and located in the groove, and a movable block arranged on the outer wall of the lead screw. This type of anti-corrosion printing plate making plate roller uses a motor to drive a cleaning brush to approach the plate roller body until the cleaning brush is in contact with the plate roller body. The rotating plate roller body is cleaned by the cleaning brush, thereby replacing traditional manual cleaning of the plate roller, improving efficiency and enhancing cleaning effect.

[0023] Among them, reference Figure 2 The mounting seat 4 includes a lower support block 25 and an upper support block 26. The lower support block 25 is fixedly mounted on the upper side of the mounting side plate 1. Semicircular grooves are provided on the opposite surfaces of the lower support block 25 and the upper support block 26. The lower support block 25 and the upper support block 26 are combined and fixed by bolts so that the two semicircular grooves form a positioning hole. The end of the printing plate roller 2 or the transmission roller 3 can be slidably inserted into the positioning hole.

[0024] The upper surfaces of the two mounting side plates 1 are respectively fixedly mounted with a first adjustment seat 6 and a reciprocating drive machine 7, a rotatable transmission rod 8 is slidably inserted in the first adjustment seat 6, a limit block 9 is arranged in the first adjustment seat 6, and the rotation angle of the transmission rod 8 is constrained by the limit block 9, an adjusting threaded sleeve 10 is fixedly mounted on the surface of the transmission rod 8, a threaded connecting rod 11 is threadedly mounted in the adjusting threaded sleeve 10, a scraper 12 is arranged parallel to the side of the transmission rod 8, the bottom end of the threaded connecting rod 11 is rotatably connected to the scraper 12, the telescopic length of the threaded connecting rod 11 is adjusted so that the cutting edge of the scraper 12 is in sliding contact with the surface of the printing plate roller 2, and when the reciprocating drive machine 7 drives the transmission rod 8 to slide left and right, the scraper 12 moves back and forth along the length direction of the printing plate roller 2.

[0025] For details, see Figure 2 A first adjusting screw 13 is rotatably installed inside the first adjusting seat 6. The first adjusting screw 13 is threadedly connected to the limit block 9.
