Aluminum plastic blister packaging machine FAQ

   There are many different forms of aluminum-plastic blister Packaging machines due to different manufacturers. The performance levels of domestic and foreign products are also very different. At present, the existing aluminum-plastic blister packaging machines can be roughly divided into the following four categories: Roller continuous aluminum-plastic blister packaging machine, plate rolling continuous aluminum-plastic blister packaging machine, flat-plate intermittent aluminum-plastic blister packaging machine, flat continuous aluminum-plastic blister packaging machine.
The aluminum-plastic blister packaging machine can be distinguished by molding and hot-press sealing, and the molding is divided into a drum type and a flat type. The flat positive pressure forming effect is better than the drum type vacuum forming; the heat sealing is also divided into the drum type and the flat type flat type hot pressing sealing effect is better than the drum type hot pressing sealing, and the drum type hot pressing sealing is in the speed, reliability, etc. The aspect is superior to the flat type thermocompression sealing.
According to the production experience, it is found that the aluminum-plastic blister packaging machine is prone to problems in blister forming, hot-press sealing, etc., and the following briefly describes how to solve these problems.
Blister molding
According to the blister forming method, the PVC film (hard piece) is heated and then passed through a mold and molded into a blister of a desired shape and size by using compressed air or vacuum. Therefore, when the formed blister has a problem, it is necessary to proceed from the following aspects. solve:
(1) Whether the PVC film (hard piece) is a qualified product;
(2) Whether the temperature of the heating device is too high or too low;
(3) Whether the surface of the heating device adheres to PVC;
(4) Whether the forming mold is qualified, whether the forming hole is smooth, and whether the air hole is smooth;
(5) Whether the cooling system of the forming mold is working properly and effectively;
(6) Whether the vacuum degree and exhaust rate of the drum type negative pressure forming can reach the normal value, and whether the pipeline has abnormal loss;
(7) Whether the compressed air of the flat positive pressure forming is clean and dry, whether the pressure and flow rate can reach the normal value, and whether the pipeline has abnormal loss;
(8) Whether the flat positive pressure forming mold clamps the PVC belt in parallel and whether there is air leakage.
2. Hot press sealing
In the hot-press sealing process of the drum type aluminum-plastic blister package, the PVC tape and the aluminum foil are hot-pressed by the mutually parallel roller-shaped heat sealing roller and the anilox roller under the action of a certain temperature and pressure. Sealed. The contact between the heat seal roll and the anilox roll is a linear contact and the required pressure is relatively small.
In the hot-press sealing process of the flat aluminum-plastic blister package, the PVC tape and the aluminum foil are heat-sealed by the parallel flat heat-sealing plate and the anilox plate in the same plane under a certain temperature and pressure. Combined. The contact between the heat seal plate and the anilox plate is in a planar contact, and the required pressure is relatively large.
Whether it is a drum type or a flat type hot-press sealing, when there are problems such as unclear heat-sealing netting, different shades of the net, and heat-closing PVC belt running position causing foaming, etc., it is necessary to solve the following aspects:
(1) Whether the aluminum foil is a qualified product, and whether the heat sealing surface is coated with a hot melt that meets the requirements;
(2) Whether the temperature of the heating device is too high or too low;
(3) Whether the operation of PVC belt or aluminum foil has abnormal resistance;
(4) Whether the heat-sealing mold is qualified, whether the surface is smooth and smooth, and whether the blister formed on the PVC belt can be smoothly inserted into the hole of the heat-sealing roller (plate);
(5) Whether the texture on the anilox roller (plate) is clear and the depth is consistent;
(6) Whether the cooling system of the heat-sealed mold is working properly and effectively;
(7) Whether the pressure required for heat sealing is normal;
(8) Is the heat seal roller (plate) and the anilox roller (plate) parallel?
3. Some advanced aluminum-plastic blister packaging machines are equipped with various automatic monitoring devices, which can play various protection functions and automatically stop the machine when the following problems are found:
(1) The safety shield is open;
(2) Insufficient compressed air pressure;
(3) The heating temperature is not enough;
(4) PVC film or aluminum foil is used up;
(5) The packaged medicines are used up;
(6) Some stations are mechanically overloaded;
(7) The circuit is overloaded.
4. At the same time, the machine cannot start running until the following problems are resolved:
(1) The safety shield is not completely closed;
(2) Insufficient compressed air pressure;
(3) The heating temperature is not enough;
(4) Lack of PVC or aluminum foil film;
(5) Overload or other faults have not been eliminated;
(6) The setting of the function button is incorrect, and the emergency stop key is not reset.
In addition to the above mentioned problems, other problems may be encountered in the actual use of aluminum-plastic packaging machines . Specific analysis of specific problems is required. Careful and careful search for the causes of problems is the key to eliminating and solving problems.
