Yingtai: The Components of High-frequency Tube Sealer

High-frequency Tube Sealer, as an essential piece of equipment in industrial production, is primarily composed of mechanical and electrical parts. The mechanical part applies pressure to the mold through mechanical transmission, enabling the workpiece to be heat-sealed and formed. The electrical part converts the power frequency electrical energy into high-frequency electrical energy through electrical components, which is then transmitted to the mold, causing the PVC plastic molecules to rearrange and generate a large amount of heat to achieve the welding effect.

The ten main components of a high-frequency heat sealing machine are:

1. Electron Tube: The electron tube acts as a high-speed switch, enabling the inductor and capacitor on the high-frequency circuit to charge and discharge, achieving oscillation.

2. Oscillation Chamber (Oscillation Barrel): The oscillation chamber is the core of the high-frequency machine. It consists of an inductor and a capacitor, made from processed aluminum plates. The oscillator is a coaxial oscillator.

3. Grid Resistor: The grid resistor is composed of one or several high-power resistors, providing a bias voltage to the electron tube.

4. Filament Transformer: The filament transformer converts 220V or 380V voltage into the voltage required by the electron tube filament (e.g., converting 380V to 6.3V).

5. High-Voltage Transformer: The high-voltage transformer converts 220V or 380V voltage into the voltage required by the electron tube anode (e.g., converting 380V to 7000V).

6. High-Voltage Rectifier: The high-voltage rectifier converts the AC voltage, after being stepped up by the high-voltage transformer, into DC voltage to supply the anode of the high-frequency heat sealing machine's electron tube.

7. Overcurrent Protection Circuit: The overcurrent protection circuit protects the electron tube from overload current.

8. Spark Protection Circuit: The spark protection circuit safeguards the mold. When sparking occurs in the workpiece, the spark protection circuit can react instantly within a hundredth of a second, stopping the high-frequency oscillation immediately.

9. Capacitor: In the high-frequency heat sealing machine, capacitors serve various functions, including bypass capacitors, coupling capacitors, and DC-blocking capacitors.

10. Inductors: In the high-frequency machine, inductors serve various functions, including high-frequency isolation inductors, circuit inductors, and coupling inductors.
