Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to an intelligent high-speed four-color cross-cutting printing machine which is convenient for replacing printing rollers. Background Art

[0002] The four-color cross-cutting printing press is a press that applies ink or pigment on the surface of the printing roller, then places the printed paper under the printing roller, and generates pressure by rotating the printing roller to transfer the ink or pigment to the paper, forming patterns, text, images and other printed products for people to use. The printing roller is one of the main accessories of the printing press and mainly plays the role of coating the ink. Impurities remaining on the printing roller during use will form a glaze layer on its surface, reducing the surface area of ​​the printing roller, so the printing roller needs to be removed for cleaning.

[0003] As disclosed in the publication number: CN211843588U, a printing press that is convenient for replacing printing rollers comprises a machine body, the top of which is fixedly connected with a first fixed platform and a second fixed platform, a placement slot is provided inside the first fixed platform, a through hole is provided on the right side of the placement slot, a motor is fixedly connected to the inner wall on the left side of the placement slot, a clamping block is fixedly connected to the output end of the motor, the clamping block is clamped on the left end of a rotating rod, a printing roller is provided on the outside of the rotating rod, and a slide slot is provided inside the second fixed platform. The printing press that is convenient for replacing printing rollers can make the fixed rod snap into or out of the fixed hole through the cooperation between the top block and the concave block, so that the connecting rod is fixed or movable in the slide slot, and the printing roller can be conveniently disassembled or installed, thereby improving the efficiency of replacing the printing roller and reducing the difficulty of the operator's work, and the device is simple to operate and suitable for promotion.

[0004] When a common intelligent high-speed four-color cross-cutting printing press that is easy to replace the printing roller is in use, although the fixed roller can be inserted into or disengaged from the fixed hole through the cooperation between the top block and the concave block, so that the connecting rod is fixed or movable in the slide groove, thereby conveniently removing or installing the printing roller, but when installing or removing the printing roller, the printing roller needs to be manually moved out of or into the printing press, which is inconvenient to operate. Since the printing roller has a certain weight, it is easy to damage the printing press during operation, and it is also easy to cause injury to the operator. Utility Model Content
