| Blister packing also called upper eyelid packing,PTP(press thoughpackaging)for short. It is one of main forms of medicine packing, which is suitfor mechanization of packaging of tablet, capsule, suppositories, pills, solidpreparation medicine, the sticky food and some electronic products.After do plenty of work of market research and analyzing the advantages ofcurrent technology and the development trend of packing machine. The authordeveloped a high speed, multi-functional and a high degree of automationpacking machine-DPP-250C plate-type aluminum-plastic blister packagingmachine. According to requirements of each index commitments, this paperresearched working mechanism and structure of aluminum-plastic blisterpackaging machine and completed the designation of overall scheme of thepackaging machine, the machine structure, driving system and control circuit.Designed and checked the cam,chain,belt and shaft in the transmission system,selected and checked the bearings. According to the requirements of high-speedpacking machine,the author innovated the structure of machine,designed usingtwo heating boards to heat the PVC in the heating box,which shorten the heatingtime. On the basis of analysis of process,make sure that the mechanism of blistermolding and hot sealing and so on must synchronize operation. After detailedcalculation,ensured the working cycle of machine and drew the working cyclediagram. Improved the design methods of packaging machinery and consideredadjustment structure and adjusting method of mechanisms.The machine was composed of mechanical transmission, electrical control,mould and base. Mechanical transmission was composed of heating,transmission, forming,hot sealing, creasing and cutting mechanism. |
