Load Cell Stability And Balance
Hanzhong Quanyuan Electronic Co.,Ltd | Updated: Oct 17, 2017

In the production of tobacco industry, the proportion of cut tobacco is one of the key technological links. The ratio of cut tobacco is the base of the cut flow in production, and the real-time and uniform blending of the stalk wire, the expanded tobacco, the sliced tobacco and the residual silk according to their respective setting ratio and cut are carried out. The matching electronic belt weigher is the core equipment to finish the process of this process. Load Cell And one of the key factors that affect its accuracy is the acquisition accuracy and stability of weighing signals, which will directly affect the quality of the cut-tobacco ratio, Load Cell and thus determine the stability and equilibrium of the intrinsic suction quality of the subsequent cigarette-end products.

The electronic belt Weigher classifies according to its work use, generally divides into the metering type, the control type, the ratio type three kinds. Metering-the instantaneous flow and cumulative weight of the measured material; control-balanced control of material weight so that the material according to the set flow through; matching type-to achieve cut, stem wire, thin slices of silk, residue, such as the setting ratio; Load Cell the proportion-type electronic belt weighing system consists of multiple weighing devices and centralized control, set weighing, proportioning in one, With the function of interactive multi-task and multi-parameter measurement, Load Cell the dynamic cumulative weighing and flow control of many kinds of tobacco can be carried out and blended according to certain proportion.

All kinds of tobacco are carried by a limited tube (or directly falling) to the belt of the weighing device, with the belt moving forward, when it through the weighing device effective weighing section, Load Cell its weight through the conveyor belt and metering roller to load sensor, sensor sensing load generated signal directly into the weighing module, The data collected and transformed by the weighing module is directly fed into the PLC data acquisition system by the S7 system bus, which detects the unit length weight q (/) on the weighing section, while the speed measuring device detects the belt running Velocity v (m/s), and obtains the instantaneous flow and the cumulative quantity and displays it through the

The ratio-type electronic belt Weigher control system is based on the material instantaneous flow of the main weighing device, as the setting flow of the mixing device, Load Cell and comparing the instantaneous flow of the mixing device with the set flow signal, the PID control operation is made by using PLC, which is compared with the matching proportion operation of the weighing device. The output speed modulation signal adjusts the speed of the motor, thus changing the speed of the belt to achieve the purpose of automatically adjusting the blending flow.

After using the electronic weighing module, Load Cell the stability of the load signal is obviously improved. In order to make the whole electronic belt weigher system accuracy and stability will achieve an optimal state, in the process of concrete use, Load Cell we should also pay attention to other factors that affect the stability of the load signal, such as: whether the bearing lubrication on the balance is good, the belt is clean, Load Cell the balance between the edge and the belt is a foreign body and so on.
