Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an automatic blister packaging machine. Background Art

[0002] The automatic blister packaging machine is a device for packaging capsule medicines. It uses various functional components to realize the hot pressing molding of capsule placement grooves and capsule filling of PVC sheets in turn, and then uses the hot air mechanism to achieve bonding with aluminum-plastic film, and finally cuts it into a whole sheet of medicines with uniform specifications.

[0003] In actual use, after the PVC sheet is used to place the capsule, it is laminated with the aluminum-plastic film to ensure that the two are close to each other, and then the two are heat-treated and bonded by a hot air mechanism. However, in this process, since the aluminum-plastic film is light in weight, and the lower surface of the PVC sheet is convex after the capsule placement groove is hot-pressed, if it is excessively squeezed during lamination, the capsule is easily ejected. If no extrusion lamination is performed, the aluminum-plastic film and the PVC sheet are easily misaligned, resulting in a decrease in the qualified rate of finished products after subsequent lamination. For this reason, an automatic blister packaging machine is specially provided to solve the above problems. Utility Model Content
