Haiwell PLC HMI four-head filling machine-wiggling cover machine solution

2020-08-07 16:36:51 market

The four-head automatic piston liquid filling machine is improved on the basis of the original two-head filling machine series products, and some additional functions are added. Make the product operation, installation adjustment, equipment cleaning, maintenance and other aspects more simple and convenient.

Widely used in daily chemical, oil and other industries, can be used for filling with different high viscosity fluids. The machine design is compact and reasonable, the appearance is simple and beautiful, the filling quantity adjustment is convenient.

2. Introduction of control scheme

The filling machine consists of three parts: Storage tank, filling mainframe and frequency conversion speed control conveyor part.

The storage tank is located in the upper part of the machine and is an normal pressure tank with liquid level sensor and feed solenoid valve.

The liquid from the previous process is put into the tank through the solenoid valve, when the appropriate level height is reached. The signal is sent out by the liquid level sensor, and the solenoid valve is closed and stopped by the electrical control part. When the material surface drops to a certain position, the feeding solenoid valve can be opened and fed again.

In the lower part of the storage tank, the outlet is connected with the suction pipe of the filling engine through the pipeline. When the main engine works, the liquid in the storage tank is pumped into the piston cylinder, and then filled into the bottle through the nozzle.

After filling completed, then send to the torsion cover machine part for mouth covering by conveyor belt.

In addition to the above control, there is an human machine interface to achieve the following control requirements:

* A parameter monitoring: HMI real-time display filling volume, filling speed, filling completion number and other operating parameters, as well as control system hand automatic switching and modification, and display process diagram;

* Alarm information: real-time display of alarm information and can query historical fault parameters;
