Check that all bottom corners of online checkweigher are uniformly stressed and locked. Check the gas pressure reducing valve to ensure that its output pressure is 0.5-0.8Mpa. Check all surfaces in contact with materials in online checkweigher to ensure that they are clean, tidy and free of any adhesive residues. Check that the outlet of the feeding weighing platform is 0.2~1mm higher than the inlet of the weighing weighing platform, and the outlet of the weighing weighing platform is 0.5~2mm higher than the inlet of the discharging belt.
