Description

Technical Field

[0001] The utility model specifically relates to the technical field of curved laser engraving devices, in particular to a printing roller pattern laser engraving device. Background Art

[0002] With the continuous advancement of science and technology, laser technology is increasingly being applied to industrial processing. Laser engraving offers significant advantages, including high precision, high speed, and non-contact processing. Laser engraving of printing roller patterns enables precise engraving of complex designs, significantly improving both quality and precision. Laser engraving also allows for rapid response to diverse design requirements, shortening product development cycles. Furthermore, the laser engraving process eliminates tool wear and mechanical vibration, reducing equipment maintenance costs and the impact on the work environment.

[0003] Chinese Patent Publication No. CN 212353421 U-type discloses an engraving machine for the production of printing rollers for mask machines, comprising a waste bin, a mounting plate welded to the left side wall of the waste bin, a motor fixed to the left side wall of the mounting plate, an output end of the motor extending to the right side of the mounting plate and fixedly connected to the driving gear, a driven gear rotatably connected to the top of the waste bin, a linkage rod fixed to the top of the driven gear, a bearing plate welded to the top of the linkage rod, a first bearing seat fixed to the top of the bearing plate, and a blower fixed to the top of the waste bin. The engraving machine for the production of printing rollers for mask machines can conveniently blow the waste chips that fall from the waste bin into the waste chip inlet through the blower and drop them into the waste bin. The use of an arc-shaped enclosure and an extension plate effectively ensures the efficiency of waste chips entering the waste bin from the waste chip inlet, reducing the generation of flying waste chips.

[0004] When the above-mentioned engraving machine for printing roller production is in use, the initial position of the laser engraving knife is close to the printing roller. When the diameter of the printing roller to be laser engraved is large, when the printing roller is placed between the first bearing seat and the second bearing seat, the laser engraving knife will hinder the placement of the printing roller, making the above-mentioned engraving machine for printing roller production unable to meet the laser engraving work of printing rollers of different diameters, causing certain obstacles to the preliminary preparation work for laser engraving of the printing roller.
