The bucket-type Electronic scale is submerged for filling, preventing the material from foaming. The parts in contact with the material are made of 316L stainless steel, which is corrosion-resistant. The double-speed filling process is fast first and then slow, ensuring both speed and accuracy. After the filling is completed, the cap is screwed on and the label is pasted and coded. The bucket separation device at the front end of the labeling machine. This is a fully automatic single-side labeling machine with high labeling accuracy, neat and wrinkle-free labeling, firm labeling, and no detachment. This is the operation situation of the entire fully automatic liquid filling production line. The filling electronic scale uses a PLC system. To ensure the accurate and reliable operation of each part of the device during the filling process, the weighing and Filling machine controls each sensor, relay, switch, and solenoid valve through the PLC program. After the filling bucket is placed on the conveyor belt, the conveyor transports it to the filling position. The proximity switch arranged at the filling position automatically senses and transmits the sensing signal to the PLC control system. The PLC controls the conveyor motor to stop rotating, and at the same time controls the lifting cylinder to drive the roller arm to rise, moving the filling bucket to the filling gun position of the filling machine. The photoelectric sensor at the end of the filling gun automatically senses the position of the filling bucket, and the cover suction device starts to suck the cover off. Then the filling gun begins to fill liquid into the filling bucket, and the weighing module transmits the weight signal of the liquid in the bucket to the PLC control system. When the preset weight is reached, the PLC controls the filling gun to stop filling, the cover suction device automatically seals the cover, and the conveyor motor is started to transport the filling bucket away. 

The weighing filling machine compares the filling weight value with the set weighing value based on the set weighing value as required. This system uses the output signal from the electronic scale as the judgment basis and realizes the control of the weighing filling machine using PLC to achieve automatic quantitative filling of materials. The weighing instrument is used to display the weight value of the materials and uses the output signal from the electronic scale as the judgment basis. The weighing instrument and the electronic scale cooperate to complete the quantitative weighing of the materials. At the same time, PLC is used to control the sequence of the filling action and is combined with related actuating drive devices to achieve the control of the electrical system for the processes such as weighing material filling, quantitative weighing, and automatic filling. The Filling system, Weighing system, and bucket discharging system are controlled by PLC to control the on-off of the filling solenoid valve, discharging solenoid valve, and bucket solenoid valve through the pneumatic system to drive the opening and closing of the hopper valve and the clamping and releasing of the material bucket. During the material filling process, automatic processing operations such as bucket clamping, material supply, weighing, and discharging need to be completed. The main structure of this designed product consists of the material supply device, weighing device, bucket device, frame, and pneumatic transmission system. The entire system action sequence is controlled by PLC.
