A high-efficiency and energy-saving plastic electric welding machine has been successfully developed on the market and put into mass production. High-efficiency and energy-saving plastic electric welding machine, special electric welding machine for sewage pipeline connection, special electric welding machine for gas/water supply, special electric welding machine for steel belt reinforced polyethylene spiral corrugated pipe, etc.
Developed and developed an electric welding machine dedicated to welding plastic pipes. The working principle, hardware structure and software design process of the system are given. The electric welding machine uses a single-chip microcomputer as the basic control unit and adopts fuzzy-PID algorithm to realize butt welding Temperature control; use the dot matrix LCD module LCM128645ZK with Chinese character library as the display device, use the two-wire serial AT24C01 chip to memorize the user's temperature setting value, and use the solid state relay SSR as the switching device for PWM control. The system is MATLAB The simulation results show that using fuzzy-PID control algorithm, the controller can play the characteristics of fuzzy control with strong robustness, good dynamic response, and small overshoot. At the same time, it has the dynamic tracking quality and steady-state accuracy of PID controller. Very good real-time performance. Practical applications show that the control device has the advantages of small size, strong anti-interference ability, convenient use and strong versatility.
