[0035] The working principle and use process of the utility model are as follows: after the user starts the cylinder 4 to drive the cutting knife 3 to move downward to cut the paper corner, the cutting knife 3 will generate a downward force on the movable bar 7, and then the movable bar 7 moves downward under the action of the cutting bar, so that the bottom of the movable bar 7 contacts the top of the contact detector 6, so that the contact detector 6 detects the current contact with the movable bar 7, and then the contact detector 6 will send an electrical signal to increase the data displayed on the data display board 11. After the cylinder 4 drives the cutting to reset, the elastic force of the spring 8 can push the movable bar 7 to reset quickly for the next detection. In the process of the movable bar 7 moving, the movable bar 7 will drive the limit rod 91 to move up and down. Move, and then use the sliding cooperation between the limit rod 91 and the limit groove 92 to limit the tilt of the movable bar 7, so as to avoid the movable bar 7 from tilting during the movement, which makes the movable bar 7 unable to contact the contact detector 6, thereby improving the stability of the movable bar 7.

[0036] To sum up: the cutting device for producing paper corner protectors is provided with an active bar 7. After the user starts the cylinder 4 to drive the cutting knife 3 to move downward to cut the paper corner protector, the active bar 7 moves downward under the action of the cutting bar and contacts the top of the contact detector 6. Then the contact detector 6 will send an electrical signal to increase the data displayed on the data display panel 11 by one, thereby solving the problem that after the paper corner protector is cut, the number of cuts cannot be counted, resulting in the user being unable to understand the number of paper corner protectors cut that day during the use of the cutting machine, thereby affecting subsequent use.
