1、Principle and maintenance knowledge of liquid filling machine


One type of liquid filling machine, double-head automatic piston liquid filling machine: This machine has two synchronous filling heads, and the filling material is fast and accurate. It adopts German FESTO, Taiwan AirTac, SHAKO pneumatic components and Taiwan Delta's electronic control components, and its performance is stable. The material contact parts are made of 316L stainless steel. Adopting Korean optical eye device, Taiwan PLC and French electrical components. Convenient adjustment, no bottle filling, accurate filling and counting function. Filling bulkhead with anti-drip and wire drawing, filling and lifting system for anti-high foam products, positioning system for ensuring bottle mouth positioning and liquid level control system. So what are the principles and maintenance knowledge of the liquid filling machine?


Principle of liquid filling machine


A. The filling machine is a fully automatic quantitative liquid filling machine, which is suitable for filling various oils, such as lubricating oil and edible oil.


B. This model is equipped with touch screen display, variable frequency speed control conveyor belt 8 meters, automatic induction type capping machine and vacuum anti-drip device.


C. The filling machine has the characteristics of beautiful appearance, high filling precision, convenient adjustment and easy operation.


1. Man-machine interface, directly set the filling amount;


2, PLC program control, inverter speed straight line filling;


3, high-precision volumetric flowmeter, accurate and reliable quantitative;


4, mechanical seal plus vacuum suction double anti-drip;


5, first fast and then slow double flow rate efficient filling.


Liquid filling machine maintenance knowledge


One: the machine can't start:


1. Turn on the power, turn on the power switch, and check the fuse.


2. Release the emergency stop button.


3. Turn on the air pressure and keep it at around 6 kg.


4. Check if the switching power supply has DC24V power output.


5. Check if the touch screen and PLC communication line are loose.


Two: no blanking:


1. Check the air pressure and check the touch screen maintenance mode screen.


2. Check if the nozzle is closed and check the circuit.


3. Feeding.


4. Check the air pressure, check whether the injection cylinder and cylinder are dead, check whether the nozzle is closed under the touch screen maintenance mode screen, and check the circuit.


Three: filling dose is not allowed:


1. Check the feed system.


2. Filter and clean the pipeline.


3. Replace the pneumatic valve seal ring, air pipe leak, and replace the pneumatic valve.


4. Clean the solenoid valve and replace the solenoid valve.


5. Clean the sound and replace the sound.


6. Adjust the ball valve to reduce the impact force and increase the dive depth.


7. Replace the O-ring.


8. Adjust the injection cylinder magnetic switch.


Four: leakage:


1. Tighten the lower nozzle and replace the lower nozzle seal.


2. Replace the lowering tube.


3. Clean the pneumatic valve and replace the pneumatic valve gasket.


4. Replace the injection cylinder seal.


Knowledge development: filling production line


Definition of filling production line: Due to its special working principle, the production line can realize the route formed by a series of production activities, such as processing, conveying, assembly and inspection, starting from raw materials into packaging equipment. The production line has greater flexibility and can be adapted to the needs of multi-variety production. The application of the filling machine production line can realize the high-volume production of food, medicine and daily chemical enterprises, and thus help the production enterprises achieve the goal of high-speed production. In the past, the filling machine production line was not the choice of the user company.
