principle of semi-automatic filling machine

- Jul 13, 2020-

After connecting the air source, the metering cylinder is in the lower part (absorbs enough rubber material under working conditions), and will be reserved by the end of the previous work. Fill the container in place, step on the foot directional valve, the foot directional valve makes the pneumatic directional valve in the left position, and the metering pump of the semi-automatic paste filling machine supplies glue to the outside for filling. The piston rod valve of the metering drive cylinder hits the stroke directional valve, and the stroke valve is reversed, so that the pneumatic directional valve is in the right position, and the metering pump sucks the glue. After one filling, the rubber is prepared for the next filling. When continuous priming is required, set the selector switch to the closed position. At this time, the piston rod of the semi-automatic paste filling machine will refill if it touches the stroke valve. Repeatedly. If the initial infusion, the first infusion will be empty injection. The adjustment of the filling speed and the suction speed is realized by adjusting the one-way throttle valve. The adjustment of the metering value is achieved by adjusting the relative position of the stroke directional valve and the piston rod of the metering drive cylinder.

Infusion speed adjustment of semi-automatic paste filling machine: The infusion speed can be achieved by adjusting the throttle valve.

Selection of filling nozzle: its selection is related to the size of the filling container, the performance of the filling material and the filling volume. There are many types. The semi-automatic paste filling machine can choose different sizes of filling nozzles according to the different filling volume. Generally, the diameter of the filling nozzle is smaller than the diameter of the container, and the resistance is too small. The oblique nozzle with good fluidity and the flat closing nozzle with high viscosity (pictured); the special nozzle for materials. (Users can choose to do according to their product characteristics).
