Filling machines are mainly a small class of products in packaging machines. From the perspective of packaging materials, it can be divided into liquid filling machines, paste filling machines, powder filling machines, and granule filling machines. The lecture is divided into the semi-automatic filling machines and an automatic filling production lines. Recently, with the QS certification of food, edible oil manufacturers have begun to pay attention to product quality and packaging. Therefore, fuel dispensers occupy an important position in fuel dispensers.
The working principle of the filling machine:
Driven by the transmission machinery, all parties can coordinate the division of labor and achieve the effect of linkage. There is a special infrared sensor on the feeding track of the bottle to receive the induction. When the bottle reaches a certain number, it will automatically block the back bottle. After the front bottle is full, it will automatically release to fill the empty space in the back bottle. Bottle without filling. When the bottle enters the lower position of the filling head, other working parts stop and only the filling head works. When the bottle leaves, the filling head stops working, the rail part works, and the bottle stopper is released. The clean bottles from the bottle washing machine are sent to the bottle feeding screw of the filling machine by the bottle conveyor belt, and then sent to the bottle fixed cylinder of the turntable through the bottle feeding star wheel and raised. Under the guidance of the centering device, the bottle mouth tightly presses the filling mouth of the filling valve to form a seal. After emptying the bottle, the backpressure gas (CO,) in the liquid storage tank rushes into the bottle. When the air pressure in the bottle is equal to the air pressure in the liquid storage tank, the liquid valve is opened under the action of the liquid valve spring. At this time, the object is guided by the umbrella-shaped reflection ring on the return duct. It will automatically be poured into the glass bottle along the bottle wall. The carbon monoxide in the glass bottle is sent back to the liquid storage tank through the return air pipe. When the object rises to a certain height and closes the tracheal opening. Stop the object automatically. Then the liquid valve and the gas valve are closed, and the pressure gas in the bottleneck part is discharged to prevent the gas-carrying objects from spraying out when the glass bottle descends, thereby completing the entire filling process.
