Design of Cutting Machine of Paper Angle Bead

The work aims to study and design a paper angle bead cutting machine which can operate continuously, to improve the cutting efficiency. Through the study of the paper angle bead production mode and characteristics, the mechanical structure and control module of the complete machine were designed, and the principle and key control algorithm were analyzed. The mechanical part included the knife rest, the base, the tray, the transmission, etc. The rotary flying shear and eccentric wheel drive were adopted and the speed tracking of the cutter was analyzed mathematically. Based on STM32 chip, the motor was controlled and various signals were processed. The pulse signal was isolated from external interference through high-speed optical coupler. Touch screen was used for man-machine interaction, and parameters were transmitted to the controller through serial communication. The design of structure realizing the continuous cutting of paper angle bead improved the cutting speed and obtained wider processing range of paper angle bead length, and the simple operation interface increased the usability. Based on the principle of rotary flying shear, the structure continuously cutting the paper angle bead is designed, which can accurately cut the paper angle bead fed continuously.
