Description

TECHNICAL FIELD

[0001] The utility model relates to a plate roller processing equipment technical field, concretely relates to a plate roller end face polishing device. BACKGROUND

[0002] The plate roller is a component on the printing machine, which is used for transmitting the printing plate and tightly pressing on the printing substrate to complete the printing work. The plate roller is usually made of metal and has certain hardness and wear resistance, which can ensure the precision and quality of the printed matter. Different types and specifications of printing machines use different types and specifications of plate rollers. The plate roller is divided into hollow roller and solid roller, shaft roller and non-shaft roller, which is generally used for plate making. The surface of the roller is plated with copper, and the pattern is engraved by a intaglio electronic engraving machine, and then a layer of chromium is plated. After finishing, it is delivered to the printing factory, which is commonly used for printing of plastic packaging.

[0003] During use in the printing factory, the plate roller has a service life limit. When the plate roller exceeds the service life, it needs to be sent back to the plate making factory for repair. The plate roller sent back by the printing factory exceeds the service life and has a thick layer of oil on both ends. In the prior art, manual decontamination is usually used, but the manual decontamination consumes a lot of time, and the oil contains toxic substances, which affects the health of workers.

[0004] Patent CN220095923U discloses a plate roller end head oil cleaning device, which comprises a base body, a clamping mechanism for clamping the plate roller and a cleaning mechanism for cleaning the oil on the end head of the plate roller. The clamping mechanism and the cleaning mechanism are arranged opposite to each other, and the cleaning mechanism corresponds to the end head of the plate roller clamped by the clamping mechanism. The clamping mechanism and / or the cleaning mechanism are slidingly connected with the base body. However, the above-mentioned patent has some deficiencies. The above-mentioned patent can only polish the oil on one end of the plate roller. When polishing the other end, the plate roller needs to be turned over, which is time-consuming and laborious. Moreover, after long-term polishing, the brush head on the cleaning mechanism needs to be replaced, which takes time and polishing cannot be carried out during the replacement time, which cannot meet the existing work rhythm.
