Principles of liquid filling machine

The filling machine is the packaging machine of the accurate amount of packaging products in various containers. Among them, liquid irrigation machines are widely used in various industries such as dailyization, oils and other industries, and can fill various high -viscosity fluids. The design of the machine is compact and reasonable, the appearance is simple and beautiful, and the amount of filling is easy to adjust. If you want to operate the liquid filling machine, you must understand its working principle.

  Working principle of liquid irrigation machine:

  1. When the tray rises, push the bottle from the bottle mouth to the lining tube, and the plunger installed on the upper part of the support pipe will rise from time to time, the air pressure in the air pipe will decrease, and the entrance of the main filling head will open.

  2. As the tray continues to rise, the plunger will continue to rise, and the ventilation port in the upper part of the catheter will open. Due to negative pressure, the air in the air pipes and the residual nights will be discharged from the body.

  3. When the liquid filled in the bottle reaches the height of the liquid can, the filling will stop immediately.

  4. The tray and the plunger dropped together, the air in the upper part of the air catheter was compressed, so the liquid in the negative pressure in the air duct was discharged into the bottle, and then entered the top of the main entrance to close the top of the filling head. On the mouth of the storage liquid-the current outlet-the storage tank of the air catheter is in a short period of time, and then put down the tray-close the filling port to complete the filling. There are also quantitative irrigation, pressure filling and more advanced liquid level detection and filling, airflow filling, etc. There are also a variety of filling heads, and the structure of filling heads that belong to the same type of filling does not have to be the same.
