In the production line, the dynamic weight checker which is frequently used in the production line runs for several hours every day without interruption, during which a large number of products are continuously transported. Some minor faults will inevitably occur. Therefore, in view of the error problem of the on-line weight checker, we summarize some pertinent troubleshooting methods, so that users can get rid of the faults. Reference in use.
First, the instantaneous flow of the gravimeter fluctuates greatly. Solution: align the belt of conveyor with the center line of pallet;
Second,The zero point is high. Solution: It is necessary to maintain the on-line weight detection system and clean up and zero-setting operation regularly.
Third, the measurement error is large. Solution: Check the installation of solid structure of pipeline weighing equipment, correct the position of conveyor belt, measure the length of weighing bridge is appropriate, whether the instantaneous flow is normal, etc.
Fourth, the output value fluctuates frequently. Solution: It is necessary to align the belt with the center line of the tray, and then calibrate it again.
Fifth, the repeatability of calibration is not good. Solution: If the speed signal of the on-line weight detector is abnormal, it shows that the weighing signal is unstable, and the contact of the weighing sensor terminals should be checked.
6. No cumulative value under load. Solution: Clean up the dust deposited in the material box on the conveyor belt scale body, and keep the surface of the conveyor belt clean.
At the same time, we should always do the following two things:
1. Horizontal correction. Check whether the horizontal position of the weighing body of the online weighing machine is balanced. If the position is inclined, adjust the weighing foot so that the blister is placed in the center position.
2. Clean the scale. The specific method is to cut off the power supply and unplug the power cord. After soaking the gauze, wring it dry, dip it in a little neutral cleaning liquid, and use it to clean the weight of the balance tray, display the filter and separate the surface part of the scale body.
