high frequency plastic welder high frequency plastic welding machine
The high-frequency plastic welding machine mainly includes a high-frequency generator, a heating coil and a workpiece movement clamping mechanism. High-frequency plastic welding machine induction heating has very high heating efficiency, can be heated to high temperature in a very short time, and obtains an excellent hardened layer; only this kind of heat treatment technology will be greatly affected by the shape of the workpiece, not every workpiece Both apply high frequency heat treatment technology.
1. Leakage of high frequency plastic welding machine
1. The frequency of the machine is 27.12MHZ, use a frequency detection instrument to test whether the frequency is correct;
2. The machine itself is equipped with a circuit device. The high-frequency plastic welding machine checks whether the circuit connecting the machine head to the bottom plate is in good contact;

3. There is a grounded copper sheet from the rack to the upper balance board, check whether the copper sheet is pressed properly;
4. The machine is a three-phase four-wire power supply. Before starting the high-frequency plastic welding machine, please check whether the zero line is connected;
5. If the machine is placed on a wet ground, the operator of the high frequency plastic welding machine should wear rubber-soled shoes to operate.
2. The power distribution switch of the high frequency plastic welding machine tripped
When the high-frequency plastic welding machine has this fault phenomenon, you should pay attention to distinguish whether it trips when there is high-frequency output or when there is no high-frequency output. When the high-frequency plastic welding machine has no high-frequency output, it trips, please check whether the filament transformer is leaking, and whether the connecting cable has a damaged insulation layer;
This failure phenomenon of high frequency plastic welding machine is mostly a problem with the protection board: 1. Whether the spark protection sensitivity is adjusted too high; 2. Whether the shunt resistor connected in parallel with the overcurrent protection relay is open or poorly connected; 3. Resonant cavity (oscillating barrel) 4. Whether there is any leakage in the heating tube.
