Common problems in application of automatic aluminum blister packaging machine

Automatic aluminum blister packing machine can be distinguished by molding and hot-pressing sealing. According to production experience, it is found that automatic aluminum blister packing machine is easy to have problems in foam cover molding and hot-sealing. According to the principle that the PVC film is heated through the mold and shaped into the desired shape and size by compressed air or vacuum during the forming of the blister, the problems of the blister should be solved from the following aspects.

(1)Is PVC film (hard film) a qualified product?

(2) Is the temperature of the heating device too high or too low?
(3)Does the surface of the heating device adhere to PVC?
(4) whether the molding mold is qualified, whether the molding hole is smooth, whether the air hole is unobstructed;
(5) Is the cooling system of molding die working normally and effectively?
(6)The vacuum and exhaust rate of drum vacuum forming can reach the normal value. There is no normal loss of the pipeline.
(7) Whether the compressed air of the flat positive pressure forming is clean and dry, whether the pressure and flow can reach the normal value, whether the pipeline has abnormal loss;
(8)Flat plate positive pressure molding die whether parallel clamping PVC belt, whether there is leakage phenomenon.

Some advanced aluminum-plastic bubble-cover packaging machines are equipped with various automatic monitoring devices, which can play a variety of protective roles and automatically stop the operation of the machine when the following problems are found:

(1) Safety cover open;
(2) insufficient compressed air pressure;
(3) insufficient heating temperature;
(4) PVC film or aluminum foil used up;
(5) packaging of drugs used up;
(6) mechanical overload of some workstations;
(7) circuit overload.

The machine cannot start operation until the following problems are solved.

(1) The safety cover is not completely closed;
(2) the compressed air pressure is insufficient;
(3) the heating temperature is insufficient;
(4) the lack of PVC or aluminum foil film;
(5) overload or other failures have not been eliminated;
(6) the function button is set incorrectly, the emergency stop key is not reset, etc.
