The fully automatic explosion-proof liquid Filling machine adopts submerged filling method. During filling, the filling head is lowered to the bottom of the bottle first, and then the filling inlet is opened to conduct filling and measurement. This is done to eliminate bubbles generated during filling and to simultaneously raise the filling head to accelerate the filling speed. The filling weight is measured using a two-stage speed control system that is faster at the beginning and slower later, ensuring the accuracy of the measurement. Its main function is to automatically fill liquid materials to the preset weight. During the filling process, it can effectively prevent material overflow and effectively prevent the material itself from polluting the environment, thereby providing effective labor protection for operators. The system works simply, the filling is accurate. The filling machine is mainly composed of the filling head device, the system control part, the Weighing system, and the filling frame platform.

The fully automatic Liquid filling machine adopts microcomputer technology. Through the RS485 interface and the Modbus RTU protocol communication of the ARM control system, the filling machine can automatically switch between the self-flow mode and the pump-filling mode. The setting of weight parameters is realized by using weight-based intelligent judgment, enabling the automatic start and stop control of the Filling system in the pump-filling operation state, and completing the accurate measurement, display, settlement, and printing functions of the filling volume. The upper limit and lower limit settings of pressure, weight, and temperature parameters are realized by the filling system in the event of abnormal filling pipe conditions, effectively avoiding accidents. It can realize functions such as querying and automatic accumulation of filling times, filling volumes, and filling amounts.

The weighing filling machine is a measuring device that uses the rotational motion of a motor for precise weighing. It can centrally control the start and stop of the motor, browse the production flow chart, respond to accident alarms, automatically adjust the running speed of the feeding motor, and adjust the running speed of the grading motor at any time. It displays weight, current, etc. in real time, and regulates the rotational speed of the feeding motor and the grading motor. The start, operation, speed adjustment, and braking of the motor have the high functional versatility of a V/F universal inverter. The analog signal output by PLC is used as the control input signal of the inverter, and the motor speed is controlled by accepting the signal from PLC, and the working status signal of the motor is fed back to PLC.

The weighing filling machine is composed of the feeding pipe, rotor pump, Electronic scale, filling machinery, and control system. During operation, the material passes through the feeding pipe into the filling gun piston of the filling machine, and is continuously advanced by the rotor pump. At the same time, the bucket is weighed by the electronic scale. When the weight of the material reaches the preset value, the control system will automatically stop the rotation of the rotor pump to prevent the material from continuing to be fed. The weighing process is achieved through the rotation of the motor. When the material enters the filling machine, the rotor pump starts rotating, and the material moves forward. At the same time, under the action of the electronic scale, the weight of the material is continuously monitored. When the weight of the material is equal to the preset value, the control system will automatically stop the rotation of the rotor pump. Due to the adjustable rotation speed of the motor, different precision levels of weighing can be achieved by changing its speed, thus meeting the requirements of different quantitative control for filling and completing basic control functions such as data acquisition, process loop control, parameter setting, equipment sequence control, equipment operation monitoring, and alarm, as well as process control functions such as tracking the flow of liquid components in the filling process.

The electronic scale is the weighing system of the weighing filling machine that detects the weight. On the weighing touch screen, the filling amount of the required filling material for the automatic filling machine is set. If the set filling material is less than the minimum limit of the filling material or greater than the maximum limit of the filling material, the system will issue an alarm prompt. When the input filling material volume is within the set filling material volume range, it is compared and operated with the internal set value, and PLC outputs control for the three-level conveyor belt to start sequentially from the lower level to the upper level, and fill the material. If the filling material volume is less than or equal to 10% of the set material filling volume, the conveyor is in low-speed operation; If the amount of material to be filled is more than 10% of the set filling volume, the conveying will automatically switch to high-speed operation, and the filling volume of the material will also increase, thereby increasing the conveying speed and shortening the filling time of the material. When the filled material reaches 90% of the set filling volume, the conveying will automatically switch to low-speed conveying, the material filling volume will decrease, and the material filling volume will stop automatically when it reaches 100% of the set value, indicating that the material filling is complete.
