If the blister packaging machine has a whole row or a regular row or columns without foaming, the molding part is full, etc., it is necessary to check from the following aspects.
(1) Whether the temperature of the heating plate does not reach the set value before molding, check whether the temperature setting is insufficient or the heating temperature is too high, resulting in PVC stretching and thinness and molding leakage;
(2) The heating plate before molding is not parallel to the molding die or the distance between the heating plate and the molding die exceeds the distance of the blister;
(3) The heated PVC is pressed against the lower mold to cause the PVC to shrink;
(4) The upper and lower heating plates are not parallel to each other, resulting in uneven heating at one end.
(5) Whether the compressed air formed by positive pressure is clean and dry, whether the pressure during operation is lower than 0.4 MPa, and whether the pipeline has abnormal loss;
(6) The pressure of the positive pressure forming die of the plate is insufficient or the PVC tape is not clamped in parallel to check for air leakage;
