[0001] The utility model relates to the technical field of paper cutters, in particular to a positioning mechanism frame of a paper cutter. Background Art

[0002] Paper cutters are used to handle the paper cutting needs in the later stage of printing. They have developed from mechanical paper cutters to tape-controlled paper cutters, and then to cutting systems with microcomputer control, color display, full image operation-guided visual processing, and computer-aided cutting, external programming, and editing of production data, which shorten production preparation time, increase cutting accuracy, reduce labor intensity, and make operation safer.

[0003] After searching, the utility model patent with announcement number CN216152466U discloses a positioning mechanism of a hydraulic paper cutter, including a paper cutter and a positioning device, the positioning device including a fixed seat, a vertical cylinder, a push plate, a connecting seat and a connecting rod, the fixed seat is fixedly connected to the paper cutter and is arranged on the paper cutter, the vertical cylinder is connected to the fixed seat and is arranged on the fixed seat, the push plate is connected to the output end of the vertical cylinder and is located on the side of the vertical cylinder away from the fixed seat, the connecting seat is fixedly connected to the fixed seat and is located on the side of the fixed seat close to the push plate, the connecting rod is slidably connected to the connecting seat and fixedly connected to the push plate and is located on the side of the push plate close to the connecting seat, the vertical cylinder works to push the push plate forward, and then push the paper; the position of the push plate is limited by the connecting seat and the connecting rod to keep it stable, thereby achieving the purpose of pushing the paper forward stably.
