Blister packing machine is an important equipment in packaging. It can pack tablets, कैप्सूल, pills, candies, electronic cigarettes, soft capsules, big honey pills… It can also pack liquids such as ketchup, chocolate, honey, perfume, वगैरह. It is an aluminum-pvc, aluminum-aluminum dual-purpose machine. Full servo drive, each station can be adjusted by hand wheel, convenient and fast, controlled by PLC programmable program.
Blister Packing Machine Working Principle
Blister packing machines are essential in the packaging industry, providing a secure and visually way to package various products. The working principle of a blister packing machine involves several key processes: गठन, feeder, मुद्रण, and cutting. Understanding each of these processes is crucial for optimizing the operation and maintenance of the machine. Here, we’ll delve into the detailed working principle of blister packing machines.
1. Forming Station
The first step in the blister packaging process is forming the blister cavities, which will hold the products. This step can be carried out through either thermoforming or cold forming. Generally, alu-pvc blisteres is formed by hot forming, and alu-alu blisters is formed by cold forming.
Thermoforming: In this process, a plastic film (usually PVC, PVDC, or PET) is fed into the machine and heated until it becomes pliable. The heated film is then molded into the desired cavity shape using a forming die. The die presses the heated film into the mold, creating the blister cavities.
Cold Forming: For products requiring better barrier properties, cold forming is used. In this method, a laminate of aluminum foil is fed into the machine and pressed into a mold using a forming die. This process does not involve heating and is typically used for products sensitive to moisture and oxygen.
2.Feeder Station
Once the blister are formed, the next step is filling these blisters with the product. This is usually done through an automatic feeding system that accurately places the product into each blisters. The filling process must be precise to ensure that each product fits correctly into its respective blisters without spillage or misalignment.
The feeding method can be selected according to the characteristics of the material. Brush feeders, guide feeders, and special feeders can be used.
Brush feeders are generally used for aluminum-plastic packaging, and the brush will not damage the material. It uses the brush to put the tablets or capsules into each blister. This feeding method is economical and practical.
Why are some materials packaged in aluminum-plastic packaging and some in aluminum-aluminum packaging? This is determined according to the characteristics of the product. Aluminum-aluminum packaging is for some materials that need to be stored away from light.
Guide feeders are generally used for aluminum-aluminum packaging. The brush feeding method will damage the surface of the aluminum foil and even scratch it. Therefore, guide feeders are selected for fast feeding speed.
There are also special feeders, which are expensive and are not recommended unless it is the characteristics of the material.
3.Heat Sealing Station
After the blisters are filled, the next step is heat sealing. Sealing material aluminum foil over the filled blisters and bonding it. The sealing process typically involves the following steps:
Heating: The alu foil and the edges of the plastic blisters are heated to a specific temperature.
Pressure Application: A sealing die applies pressure to bond the alu foil to the plastic film, creating a secure. This ensures the product is protected from external elements such as moisture, रोशनी, and air.
4.Cutting Station
The final step in the blister packing process is cutting. The sealed blister packs are cut into individual units or strips. This step involves:
Perforation: Creating perforations between individual blister packs if they need to be separated easily.
Cutting Die: A cutting die cuts the sealed sheet into the desired shapes and sizes, producing the final blister packs ready for packaging and distribution.
The working principle of a blister packing machine is a systematic process that ensures products are securely packaged in a visually appealing and protective manner. By understanding the intricacies of forming, भरने, मुद्रण, and cutting, operators can optimize the machine’s performance, ensuring efficient and high-quality blister packaging.
