1. Typical applications

It is suitable for quantitative filling of 200L foam free liquid in chemical, food and pharmaceutical industries.

2. System Overview

GZM-200L explosion-proof liquid upper type liquid quantitative filling scale adopts liquid surface filling method, which is suitable for filling a variety of foam free liquid materials. The uniquely designed filling head device is easy to operate, with fast and accurate filling; And ensure to the greatest extent possible the leakage of residual liquid upon completion of infusion. When operating, the operator only needs to simply align the barrel mouth directly below the filling head, press the [Start] button on the handle, and the filling head will automatically insert into the barrel, and the empty barrel will be automatically peeled. Then open the filling valve and accurately fill at two speeds; After the filling is completed, the filling head automatically lifts to the outside of the bucket, the drip tray automatically connects to the bottom of the spray gun, and the bucket is manually pushed out of the weighing table by rotating the cover to complete the process.

3. System features and functions

The entire system is manufactured according to explosion-proof standards, with an explosion-proof level of EXdiaIIBT4

The control system is manufactured using high-end electrical components such as Mitsubishi PLC programmable controllers from Japan, with reliable performance;

The filling gun is our company's proprietary design, which allows for quick disassembly and easy maintenance with bare hands;

The sealing and soft connection parts are made of Teflon, which is solvent resistant, acid and alkali resistant, and has a long service life;

The system adopts a two-stage adjustable filling method for large and small materials, which improves accuracy and production capacity;

■ Equipped with automatic protection function for the top bucket, used to automatically lift the filling gun when it is not inserted into the bucket and not perform filling;

Unique anti drip device to prevent materials from dripping onto barrels and weighing platforms, affecting packaging and rollers;

Choose two filling modes, net weight and gross weight, to meet the different filling needs of users;

Free setting of target quantity, suitable for quantitative filling in various weight ranges;

Dual window display dedicated filling control instrument, which can display information such as target quantity, filling quantity, number of barrels, cumulative quantity, etc;

The filling head height can be manually adjusted, suitable for packaging drums of different heights;

Equipped with automatic identification of the tare weight range of empty barrels and the function of filling without barrels;

Equipped with automatic detection of filling target quantity exceeding the tolerance function, and can freely activate the automatic drop correction function;

The controller is equipped with manual buttons and emergency stop buttons for all actions, for use in special situations;

The controller can store 30 sets of filling value parameters, which can only be called when in use;

Equipped with self fault diagnosis, interface testing, digital calibration, anti vibration setting, and upper computer communication functions;

Adopting one click operation: start - gun head descent - automatic peeling - filling - completion of gun lifting - leak detection.

6. Workflow

A. The operator moves the empty barrel to the weighing platform, so that the filling gun head is directly above the barrel mouth;

B. The operator presses the [Start] button;

C. The filling head is automatically inserted into the barrel and the weight of the container is checked to be qualified. The tare weight is automatically removed, and the ball valve and the bottom valve of the gun head are opened for quick filling. When the weight reaches a small material value, the filling speed decreases. When the weight reaches the target amount and reduces the advance amount, the two valves are fully closed. The filling head automatically lifts the gun out of the barrel, and the anti drip tray receives the liquid. Error detection and display are performed;

D. The operator moves the heavy bucket out of the weighing platform and turns the lid. A filling process is completed;

E. Repeat steps A-D for continuous filling.
