After the closed-loop control system along the roller conveyor belt installation package and calibration scales, with the central controller on the controller control room, packing machine machine closed loop control system for continuous correction heavy bag. Special attention is required in the closed-loop control system, heavy bag as a reference to calibrate the scale, the scale calibration testing including tare weight of the total weight of each bag, there is no automatic tare function, you can not make adjustments to its tare weight change, Therefore, the production process must be cleared up ash, remain stable zero point calibration scales. Works: BGY50 packaging machine, with the new system as a weighing device, mechanical, mechanical and electrical integration, control of the whole process of packing double mouth cement packaging machine, the operator simply plug in the bag, it can be done automatically by the device packaging cement packaging machine company, get qualified satisfaction. When the artificial plug bag, while touch sidekicks signal switch, packaging machines get the signal, three cylinder open the floodgates, unloading indoor cement at high speed rotating blades role ejected through the discharge nozzle, when a set of cement filling given the weight (eg 45Kg), metering devices to signal a single mouth cement packing machine, gate control system actuation of the gate in a half-open position, so that the filling stream flow from the crude state to a trickle until reaching the calibration weight cement packaging machine, measuring device emits a signal once again the shutter is completely closed, while the pressure bag is released, fell on the cement bag belt conveyor transported away from the packaging machine tray, complete a cycle of packaging. Single-mouth cement packing machine, Zhejiang cement packing machine, mechanical and electrical equipment supplied by Chi Long Chi Long Electrical Equipment Co., Ltd. Weifang. Weifang Chi Long Electrical Equipment Co. (www.wfbaozhuangji.com) strong, credible, Shandong Weifang versatile packaging machine industry has accumulated a large number of loyal customers.
