How to solve the problem of checkweigher not weighing
How to solve the problem that the automatic checkweigher cannot be weighed As a high-speed and high-precision online checkweighing product, a large number of products must be transported uninterrupted every day, and it needs to work for many hours without stopping. High-intensity operation will inevitably occur Some minor glitches. So how do you deal with these glitches? 1. The zero point is too high. Solution: It is necessary to regularly maintain the automatic checkweigher machine system and clean up the zero-adjustment operation; 2. The measurement error is large. Solution: Check whether the installation of the solid structure of the assembly line weighing equipment is firm, correct the position of the conveyor belt, measure whether the distance between the weighing bridge is appropriate, whether the instantaneous flow is normal, etc.; 3. There is a load without cumulative value. Solution: Clean the dust accumulation in the material box on the conveyor belt scale body, and keep the surface of the automatic checkweigher machine belt clean; 4. The instantaneous flow fluctuates greatly. Solution: Align the conveyor belt with the center line of the pallet; 5. The repeatability is not good during calibration. Solution: If the speed signal of the checkweigher is abnormal, it means that the weighing signal is unstable, and you should check whether the terminals of the load cell are in good contact. 6. The output value fluctuates frequently. Solution: It is necessary to align the belt with the center line of the pallet, and then re-calibrate; In addition to the above six points, the following two things need to be done regularly: 1. Level calibration. Check whether the horizontal position of the scale body of the checkweigher is balanced. If the position is inclined, please adjust the scale feet so that the blisters are placed in the center. 2. Clean the scale body of the checkweigher machine. Specific steps: 1. Cut off the power → unplug the power cord. 2. Wet the gauze and wring it out → dip in a little neutral cleaning solution → use it to clean the weight sorting scale tray, display filter and the surface part of the sorting scale body.
