The Liquid automatic filling scale adopts the filling method on the liquid surface, which is suitable for filling a variety of non-foaming liquid materials. The uniquely designed filling head device is easy to operate, filling quickly and accurately; and maximize the guarantee of residual liquid dripping when filling is completed. Adopting large turntable bearing and linear rail, it can move around the column left and right, front and back, and the pneumatic operation knob is more convenient for operation, which is easy and quick to operate, with left and right disc brakes and front and rear side brakes, which can prevent the filling gun from touching the mouth of the barrel, and make the filling more convenient.
020-34563445After the automatic liquid filling scale calibrates the tare weight, it outputs a fast feeding signal to the feeding device, causing the fast feeding cylinder in the feeding device to control the feeding door to open rapidly, and the material flows into the weighing hopper at a relatively large flow rate. By receiving signals from the weighing sensor, the system continuously monitors the weight changes in the weighing hopper. When the weight of the material entering the weighing hopper approaches the fast feeding set weight, the system controls the fast feeding cylinder to quickly close, and the fast feeding signal switches to a slow feeding signal. At this time, the material flows into the weighing hopper at a smaller flow rate to ensure that the system controls the material flowing into the weighing hopper with high precision.
The operation of a liquid filling scale includes: calibrating the tare weight → fast feeding → slow feeding → weighing calibration → unloading. The control system checks the tare weight. If the tare weight is not zero, the weight compensation is given to the filling set weight to ensure that the net weight of the weighed material is not affected by the tare weight of the weighing hopper and always remains at the user's set value.
The control system, through the operation of the system's mathematical model, can accurately predict a lead amount, stop the entire feeding process, and make the final weight of the material in the weighing hopper set by the user. After the feeding is completed, the system enters the weighing verification state. The purpose of weighing verification is to further confirm whether the weight of the material entering the weighing hopper is within the allowable range of the user's set weight error after both fast and slow feeding stop. If it is within the error range, the system will perform the unloading operation; otherwise, the system will alarm and wait for the operator to handle it. After the operator has completed the handling, the system will continue to run.
After the system has completed unloading, the unloading door in the weighing hopper closes immediately, thus completing one cycle of operation for the system. At this point, if the operator sets it to continuous working mode, the system will start the next cycle of operation. The filling barrels, which are already filled with materials, fall onto the containers and undergo processes such as capping and transfer.
