Paper cutter positioning mechanism for printing processing

The utility model relates to a paper cutter positioning mechanism for printing processing, which comprises a worktable, a paper cutter body is fixedly mounted at the top of the worktable, and a limiting mechanism for positioning cut paper is arranged on the left side of the paper cutter body. The limiting mechanism comprises connecting plates, transverse plates, limiting grooves, limiting blocks, telescopic springs, limiting plates, fixing plates, threaded rods and positioning rollers, the connecting plates are fixedly mounted at the bottoms of the two connecting rods, the transverse plates are fixedly mounted at the bottoms of the two connecting plates, and the limiting grooves are formed in the opposite sides of the two transverse plates. According to the positioning mechanism of the paper cutter for printing processing, through the arrangement of the limiting mechanism, in the forward pushing process of paper, the front side of the paper makes contact with the limiting plate, the left side and the right si
