The structure principle of toothpaste filling and sealing machine

The structure principle of toothpaste filling machine

1. The injection method at the bottom of the tube.

2. Use the original air heater.

3. Actively press the hose into the tube mold.

4. Use elastic and tightening tube cups to ensure that the sealing height is consistent.

5. After the fan, the harmful gas generated after heating is discharged to the outside.

6. After the tail is sealed, it is equipped with an air cooling system to prevent heat from being transferred to the paste.

7. The injection system of the mechanical transmission method is selected to ensure the stability of the filling amount.

8. The inner wall of the tube is sealed with hot air, and the outer wall of the tube is cooled by circulating cold water. Make sure the end cap is beautiful.

9. The automatic color marking system of stepping drive the rotation of the tube cup is selected, which can automatically mark the oval and other special-shaped tubes.

The working principle of toothpaste filling and sealing machine

The high-voltage high-frequency electrical signal of 20KHZ is generated by the ultrasonic generator, and then the high-frequency electrical energy is converted into mechanical vibration energy by the ultrasonic converter. The ultrasonic tail sealing mold acts on the plastic hose, and the temperature transmitted to the interface increases through the friction between the surface of the hose and the internal molecules. When the temperature reaches the melting point of the hose itself, the hose interface rapidly melts. Then it fills the gap between the joints. When the vibration stops, the hose is cooled and shaped under a certain pressure to achieve perfect welding. The welded workpiece meets practical requirements such as watertightness and airtightness.
