Working principle
Through the cylinder's movement of forward and backward to make the piston which is located in the cylinder do reciprocating movement, so as to occur the negative pressure in the preceding chest of the cylinder
The piston is pulled backward when the cylinder make forward movement, the material cylinder occurred negative pressure, the materials in the barrel are pressed into the feeding pipe by pressure and go into the material pipe through unidirectional valve of feeding and discharging materials .
It adopts pneumatic vacuuming and capping. Simply put the bottle into the lower mold, click the start button, and the device will automatically vacuum the cap and finish it at the same time. The machine is also equipped with an automatic operation switch. When the gear switch is switched to the automatic position, the device will automatically run without having to click the start button every time.
This machine can choose different capping heads and lower caps according to different bottle types and calibers, regardless of bottle type. The capping tension and vacuum strength can be adjusted to
achieve the best results.
