The workflow of the blister packaging machine
1. PVC preheating of blister packaging machine
Start the machine to heat up. Close the upper and lower heating plates, and heat the PVC plastic sheet between the upper heating plate and the lower heating plate. After preheating, under the action of traction, it enters the blister forming mold. The upper molding die for blister molding is fixed, and the lower molding die rises to the upper limit under the action of the cam and presses the PVC plastic sheet hard. At this time, the air valve is opened, and the compressed air passing through the filter pressure reducing valve enters the cavity of the lower molding die through the upper molding die, and the PVC plastic sheet is formed by positive pressure.
2. Feeding of blister packaging machine
After forming the PVC plastic sheet into a certain shape, the feeder will transport the packaged material into the blister. Specially shaped materials are manually fed. It is equipped with a photographic inspection system that can automatically remove debris from the printing plate.
3. Heat sealing of blister packaging machine
After charging and heating the PVC blister and aluminum foil, they are bonded in a linear or point-sealed manner so that the material does not come into contact with the outside world.
4. Blister packaging machine printing number and batch number printing
For the already formed plates, print codes.
5. Blanking of blister packaging machine
According to the requirements and output of the board, the contour of the finished PVC is punched out.
