The bucket scale is equipped with an environmentally friendly frame, a visible window, and automatic lifting and sliding doors for loading and unloading buckets. During filling, a closed space can be formed. The Electronic scale is composed of a PLC programmable controller, weighing module, and visual system, etc. It has strong control capabilities and a high degree of automation. The PLC has an Ethernet communication interface, which can communicate with the owner's system. This machine has functions such as not filling without a bucket and not filling if the bucket opening is incorrect, avoiding waste and pollution of materials and preventing contamination. It also demonstrates excellent performance in the integration of mechanical and electrical systems. 

The filling electronic scale achieves the input of pulse frequency through weight sensing. When the frequency of the pulses decreases, the speed of the stepper motor slows down; when the frequency increases, the speed increases. To achieve adjustable measurement size and improve measurement accuracy, it is required that the rotational speed of the screw be adjustable and the position be accurately positioned. A stepper motor is used to control the rotational speed and number of rotations of the screw. This not only simplifies the mechanical structure but also makes the control very convenient. Without overloading, the rotational speed of the stepper motor and the stopping position only depend on the frequency and number of pulses of the pulse signal, and are not affected by changes in load.
