Technical Field

[0001] The utility model relates to the technical field of paper cutters, in particular to a paper cutter capable of preventing deviation. Background Art

[0002] A paper cutter is a mechanical device used to cut paper, cardboard and other materials. It can cut paper, cardboard and other materials into the required size and shape. There are many types of paper cutters, the most common ones are manual paper cutters, electric paper cutters, hydraulic paper cutters, etc. Different types of paper cutters have different characteristics and applicable scopes, and can be selected according to actual needs. Paper cutters have been widely used in printing, packaging, paper product processing and other industries.

[0025] The side of the plug rod 21 close to the lifting plate 6 is fixedly connected to the surface of the lifting plate 6, and a slot 22 is provided on the inner side of the gantry 4. When the cylinder 5 is started, the output shaft of the cylinder 5 will push the lifting plate 6 to slide downward, and the lifting plate 6 will drive the plug rod 21 to slide in the slot 22, and the plug rod 21 will gradually move downward, the plug rod 21 is located on the inner side of the slot 22 and is slidably connected to the slot 22, the inclined block 23 penetrates the gantry 4 and is slidably connected to the gantry 4, and a contraction cavity 24 is provided on the inner side of the cutting table 1, and the inclined block 23 The insert rod 21 penetrates the contraction cavity 24 and is slidably connected. After the insert rod 21 moves downward for a certain distance, the arc surface at the bottom of the insert rod 21 will conflict with the inclined surface of the inclined surface block 23, thereby forcing the insert rod 21 to push the inclined surface block 23 to retract into the contraction cavity 24. The surface of the inclined surface block 23 located inside the contraction cavity 24 is fixedly connected with a positioning rod 25, which penetrates the cutting table 1 and is slidably connected. The left side of the inclined surface block 23 is fixedly connected with a spring 1 26, and the end of the spring 1 26 away from the inclined surface block 23 is fixedly connected to the inner side of the contraction cavity 24.
