This machine is a flat-plate aluminum-plastic-aluminum blister packaging system designed for sealing capsules, tablets, pills, and similar products. It uses a main drive transmission and control system to complete forming, filling, sealing, coding, and cutting in a continuous process. The equipment is built in modular sections, which allows the line layout to be adjusted according to different packaging formats and production requirements.
Performance characteristics
Main drive system
The main drive uses a large-power transmission mechanism. The main shaft is driven by a chain row rather than a conventional gear train, which reduces gear-related noise and positioning error during long-term operation. This arrangement improves running stability and makes the machine easier to maintain.
Electrical control system
The control section uses imported electrical components. Depending on production needs, the machine can be equipped with a missing-material replenishment device and a defective-product detection and rejection device. The replenishment device automatically adds material when a cavity is detected as empty, so the packaging process remains continuous. The detection and rejection device identifies and removes incorrectly filled or sealed units, which helps maintain packaging quality.
Sectional modular design
The machine is arranged in two main sections. The first section handles PVC forming, feeding, and heat sealing to create the base blister cavities and fill them. The second section performs cold forming of tropical aluminum, heat sealing, and punching to complete the aluminum seal and cut the finished blister cards. This separated design allows the production flow to be adjusted for different blister sizes, materials, and process sequences. For critical non-standard parts in these modules, such as forming dies, sealing plates, and guide rails, we can provide custom machining based on customer-supplied drawings.
Photoelectric control system
A photoelectric control system is used for automatic feeding of PVC, PTP aluminum foil, and rigid aluminum, as well as automatic scrap edge punching. The system maintains synchronization across long-distance multi-station operation, reduces manual intervention, and improves overall production efficiency.
Optional photoelectric detection and correction device
An optional photoelectric detection and correction device can be added, working with an imported stepping motor for traction. This supports registered printing and packaging with graphic alignment. The feature improves visual consistency of printed blister cards and is suitable for products that require higher packaging appearance standards.
Applicable products
The machine is suitable for blister sealing of capsules, uncoated tablets, sugar-coated tablets, soft capsules, injection vials, irregularly shaped tablets, and other pharmaceutical products. It can also be used for packaging of medical devices, light chemical products, food items, and electronic components.
Working process
Forming
The upper and lower heating stations soften the PVC material so that blister cavities can be formed into the required shape.
Heat sealing
After the cavities are filled, the upper heating station seals the PVC to the aluminum foil, creating a closed blister cavity.
Coding
Production date, batch number, and other required information are printed on the package surface for traceability and identification.
Indentation
The package is creased to assist later cutting or folding. In some processes, slight heating is applied to improve the crease quality.
Cutting
A cutting station separates the continuous web into individual finished blister cards with consistent dimensions and clean edges.
Output
After all operations are completed, the finished blister cards are conveyed out for downstream packaging or direct storage.
Summary
The machine combines modular construction, chain-driven main transmission, and photoelectric synchronization to complete forming, filling, sealing, coding, and cutting in a continuous automatic process. Its main characteristics are low operating noise, stable long-distance synchronization, configurable optional modules, and broad applicability to pharmaceutical and light industrial blister packaging. Hansheng Automation can provide custom precision machining for critical non-standard parts used in this type of equipment, based on customer drawings or samples.
