In operation, the paper cutter manufacturer should also consider the convenience of operation and the friendliness of human-computer interaction. Generally produced paper cutters need to have certain automation functions. When the paper is input, the machine needs to start cutting by itself, or only one or two buttons can be started to work, of course, the latter is considered from the aspect of safety performance. The second is whether the machine has a relevant detection function after the paper cutting is completed, which can make the paper cutter stop automatically to ensure the efficiency of the next paper cutting and the safety of this paper cutting. These functions need to be considered and implemented by the cutter manufacturer at the beginning of design.
