Design and application of electric fusion welding machine

A high-efficiency energy-saving plastic electric fusion welding machine has been successfully developed in the market and put into production in large quantities. High-efficiency and energy-saving plastic electric fusion welding machine, special electric fusion welding machine for sewage pipeline connection, special electric fusion welding machine for gas / water supply, special electric fusion welding machine for steel belt reinforced polyethylene spiral corrugated pipe, etc.

Developed and developed an electric fusion welding machine dedicated to plastic pipe welding. The working principle, hardware structure and software design flow of the system are given. The electric fusion welding machine uses a single-chip microcomputer as the basic control unit and uses fuzzy-PID algorithm to achieve butt welding. Temperature control; LCM128645ZK dot matrix liquid crystal display module with Chinese character library is used as display device, two-wire serial AT24C01 chip is used to memorize the user's temperature setting value, and solid-state relay SSR is used as the PWM-controlled switching device. The simulation results show that using fuzzy-PID control algorithm, the controller can exert the characteristics of strong robustness, good dynamic response and small overshoot of fuzzy control, while also possessing the dynamic tracking quality and steady-state accuracy of PID controller. Very good real-time performance. Practical application shows that the control device has the advantages of small size, strong anti-interference ability, convenient use and strong versatility.
