Description

Technical Field

[0001] The utility model relates to the technical field of gravure printing roller electric engraving, in particular to a gravure printing roller protection structure. Background Art

[0002] Gravure printing, referred to as "gravure printing", is a plate-making technology in which an image is carved into a recessed shape from the surface. In the existing gravure plate roller processing process, an electric engraving machine is used to engrave on the plate roller to produce a gravure print on the plate roller, and then the processed gravure plate roller is used for printing.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that Chinese Patent Publication No.: CN217968827U discloses a protective structure for an electric engraving gravure plate roller, including an electric engraving machine operating table, both sides of the top of the electric engraving machine operating table are fixedly connected with sealing covers, and both sides of the top of the electric engraving machine operating table are fixedly connected with rotating brackets. In the utility model, the U-shaped protective cover is pulled to translate on the top of the electric engraving machine operating table. At this time, the rack on the U-shaped protective cover is meshed with the corresponding circular gear for transmission, so that the main bevel gear and the slave bevel gear are meshed with the transmission rod to rotate. At this time, the slave bevel gear at the other end of the transmission rod drives the corresponding main bevel gear and the circular gear to rotate in the opposite direction, so that the two U-shaped protective covers move synchronously relative to or opposite to each other to open or close. It only needs one hand to operate and is convenient to use; pull the brush plate on the waist groove so that the adjusting rod drives the brush plate to brush the inner side of the glass plate to avoid sewage adhering to the glass plate and blocking the processing position, so that the operator can observe the processing status conveniently.

[0005] However, the above patent still has some problems that need to be improved during actual use. The most obvious one is that after repeated use, a gap will form between the brush plate and the glass plate due to wear, resulting in the brush plate being unable to fully fit with the inner side of the glass plate, thereby affecting the cleaning effect and efficiency of the sewage on the glass plate.

[0006] To this end, we proposed a gravure printing roller protection structure to solve the above-mentioned drawbacks. Utility Model Content
