The electronic bucket material scale adopts computer automatic control for the weighing operation of the Electronic scale, a vacuum suction system to ensure no dripping or leakage, and fast and slow speed double-speed filling to ensure filling accuracy; the structure is compact and reasonable, the operation is stable and reliable, and the installation and operation are simple. The automatic Filling machine has functions such as accurate measurement, fast filling speed, convenient cleaning, drip-proof, automatic hole insertion function, ensuring no dripping or leakage with fast and slow speed filling, ensuring filling accuracy, automatic hole insertion function, saving time with an arbitrary stop button, facilitating cleaning of the pipeline and disuse. The liquid filling scale through the RS485 interface, ModbusRTU protocol communication of the ARM control system, can achieve automatic switching between the gravity flow mode and the pump liquid addition mode, setting of weight parameters, using weight intelligence judgment, can realize automatic start-stop control of the Filling system under the pump liquid addition operation state, and complete the accurate measurement, display, settlement, and printing functions of the filling volume, setting of upper and lower limits of pressure, weight, and temperature parameters, realizing the emergency cut-off function in the abnormal state of the filling pipeline, effectively avoiding accidents. It can realize functions such as query and automatic accumulation of filling times, filling amounts, and filling amounts.

The Liquid filling machine includes a filling machine frame, an electronic scale support, a conveying platform, and a material container; the circumferential surface of the material cylinder is provided with a filling valve, through a track composed of an upper ring and a lower ring in an inclined position, using this track to control the piston to alternately draw the material in the material cylinder into the material cavity or press the material in the material cavity into the container, while cooperating with the use of the electronic scale to control the operation of the driving mechanism, opening or closing the ascending channel by the swing rod, thereby making the feeding channel connect between the feeding port and the material cavity or the filling channel connect between the filling port and the material cavity, consisting of the feeding valve plug, the piston, and the support ring, effectively controlling the output of the material. When the piston rod drives the feeding valve plug to move upward, due to the friction between the piston sealing ring and the cylinder wall, its movement lags, causing the feeding port to open; continuing to move upward, the limit block push component component moves upward, the lower cavity of the material cylinder forms a vacuum, only the periphery of the supporting ring is open, the material will flow along the direction indicated by the arrow in the figure into the material cylinder until the feeding action is completed. When the piston rod and the feeding valve plug move downward, the movement lags, the feeding valve plug contacts the piston and seals, and continues to push downward, the material is pushed out to complete the discharging action.

The automatic filling machine is driven by a stepless speed regulating motor, achieving the movement of the lifting worktable, and on the filling machine lifting worktable, there is a liquid storage and filling gun for filling, the outer wall of the storage and filling gun is evenly distributed with hydraulic cylinders, the material cylinders are connected by a lifting type filling valve. The liquid in the storage and filling gun is supplied by an electromagnetic directional valve, during operation, the filling gun is set by the electronic scale to the target value, sucks liquid from the storage tank, so the liquid level in the storage tank changes constantly, sensors must be set at the lowest and highest liquid levels, when the storage and filling gun is at the lowest liquid level, its sensor sends a signal, making the electromagnetic directional valve open, the liquid in the high-level storage tank flows into the storage and filling gun. When the liquid level in the tank reaches the highest point, its sensor sends a signal, making the electromagnetic directional valve close, then the high-level storage tank stops supplying liquid to the storage and filling gun. To achieve the above working principle, it is required to set an automatic control circuit for the position.
