Hot pressure sealing of blister packing machine

In the process of hot pressing sealing of the drum type aluminum plastic bubble cover packaging, the pvC-belt and aluminum foil are closed by meshing the roller and the roller, which are parallel to each other, under a certain temperature and pressure. The contact between the heat sealing roller and the roller is linear, and the pressure required is relatively small. In the process of hot pressing sealing of plate type aluminum plastic bubble cap packaging, pvC-band and aluminum foil are completed by parallel plate heat sealing plate and reticulated plate in the same plane under the action of certain temperature and pressure. The contact between the heat sealing plate and the reticulated plate is a surface contact, and the pressure required is either cylindrical or flat type hot sealing, when the heat sealing reticulated is relatively large. Clear, different shades of reticulation, thermal bonding P V C with running position caused by rubbing foam and other problems need to be solved from the following aspects:

(1) whether aluminum foil is qualified product, whether the thermal bonding surface is coated with thermal sol in line with the requirements;

(2) whether the temperature of the heating device is too high or too low;

(3) whether there is abnormal resistance to the operation of the P V C band or aluminum foil;

(4) whether the heat sealing mold is qualified, whether the surface is smooth and smooth, whether the bubble cap formed on the PVC belt can be successfully set into the holes of the heat sealing roller (plate);

(5) the anilox roller (plate) on the anilox grain is clear, consistent in depth;

(6) Whether the cooling system of the heat sealing mold works normally and effectively;

(7) Whether the pressure required for heat sealing is normal;

(8) whether the heat sealing roller (plate) and anilo roller (plate) parallel.
