Description

Technical Field

[0001] The utility model relates to the technical field of grinding mechanisms, in particular to a grinding mechanism for folding and feeding paper in a printing machine. Background Art

[0002] The paper conveyor belt for the folding part of the printing machine is generally a belt, and the belt needs to be ring-shaped. Therefore, the two ends of the paper conveyor belt need to be glued. In order to glue firmly, the rubber on the surface of the paper conveyor belt to be glued needs to be polished rough and thin. After searching, a Chinese patent with authorization announcement number CN218017491U discloses a printing machine folding paper conveyor belt grinding equipment. When using it, the staff uses a clamping device to fix the paper conveyor belt on the surface of the mobile platform. The workers can accurately control the position of the mobile platform through the scale line, so that the grinding area of ​​the paper conveyor belt is aligned with the grinding device, and the grinding device grinds the paper conveyor belt. However, the clamping device When in use, press the moving block, the moving block compresses the spring, causing the spring to shrink into the storage chamber, and place the two ends of the paper feed belt between the fixed blocks of the two clamping devices respectively, and then place the clamping block between the two fixed blocks, use the clamping block to clamp and fix the paper feed belt, and then release the moving block. At this time, the compressed spring releases its elastic force, and pushes the moving block out of the storage chamber, so that the moving block fixes the clamping block. Finally, the staff inserts the clamping bolt into the jack, and then screws the clamping bolt into the positioning hole, so that the clamping bolt fixes the clamping block. This clamping method is too cumbersome and cannot achieve positioning quickly. At the same time, it is not easy to align the conveyor belt for clamping. Utility Model Content
