After the automatic Filling machine enters the automatic operation state, open the feeding door and start feeding. The feeding device is fast and slow two-stage feeding mode. When the weight of the material reaches the fast feed set value, stop the fast feed and keep the slow feed; When the weight of the material reaches the final set value, close the feeding door to complete the filling process; The unloading door of the weighing hopper will be automatically closed after the material is discharged, and the material will be automatically transported down. Gland and transfer to next station. Such a cycle of automatic operation. The most direct and accurate way of mass quantification is through weighing.

The Liquid filling machine is composed of electronic weighing unit, conveying device, cylinder filling gun, lifting mechanism, etc. The storage silo is a buffer silo for material storage and provides a nearly uniform material flow; The gate is located at the bottom of the storage bin and is used to seal the material in the storage bin when the equipment is repaired or fails. The cutting device is composed of a cutting hopper, a cutting door, a pneumatic component, a filling valve, etc. It provides fast and slow feeding in the process of electronic weighing, and the material flow of the fast and slow feeding can be adjusted separately to ensure that the quantitative filling meets the accuracy and speed requirements of the measurement. The function of the filling valve is to balance the air pressure difference in the liquid filling machine; It is mainly composed of a weighing bucket, a bearing bracket and a weighing sensor, which completes the transformation of the weight to the electrical signal and transmits it to the control unit; The electrical control device is composed of a weighing controller, electrical components and control cabinet, which is used to control the filling work of benzene liquid and make the whole filling work orderly according to the pre-set program.
