What are the main Parts of Blister Packing Machine?

As a professional in the pharmaceutical packaging industry, you're undoubtedly familiar with blister packing machines. These devices are widely used in pharmaceutical, food, and consumer goods industries to efficiently package products in plastic or aluminum foil blisters. This article will provide you with a detailed introduction to the main components of a blister packing machine, helping you better understand and operate this complex equipment.

 

1. Feeding System

The feeding system is the starting point of the blister packing machine, responsible for accurately delivering products to the packaging position. This system typically includes the following components:

- Vibrating bowl: Used to arrange and transport bulk products in an orderly manner.
- Conveyor belt: Transfers products from the vibrating bowl to the packaging position.
- Counting device: Ensures the correct number of products are placed in each blister.
- Hopper: Temporarily stores products waiting to be packaged.

You should note that different types of products may require different feeding methods. For example, for fragile tablets, you might need to use gentler feeding methods such as gravity feeding or soft brush feeding.

 

 

2. Forming Station

The forming station is the core part of blister packaging, responsible for shaping flat plastic or aluminum foil material into blisters with cavities. The main components include:

- Heating device: Heats the plastic material to a pliable state.
- Pressure forming mold: Presses the heated material into the desired blister shape.
- Cooling system: Rapidly cools the formed blisters to maintain their shape.
- Vacuum device: Creates a vacuum during the forming process to ensure precise blister shapes.

You need to choose suitable molds based on the size and shape of different products. Regularly checking and maintaining the various components of the forming station can ensure the quality and consistency of the blisters.

 

 

3. Filling Station

The filling station is responsible for accurately placing products into the formed blisters. The precision of this stage directly affects the quality and efficiency of packaging. The main components include:

- Pusher: Pushes products into the blisters.
- Positioning device: Ensures products fall accurately into each blister.
- Detection system: Checks for missing or incorrectly placed products.
- Cleaning device: Removes any product residue that may adhere to the edges of the blisters.

You can adjust the parameters of the filling station, such as pushing speed and force, to accommodate different types and sizes of products.

 

4. Sealing Station

The sealing station's function is to seal the blisters containing products with a covering material (usually aluminum foil). This process is crucial for protecting the product and extending its shelf life. The main components include:

- Heating device: Heats the sealing material to the appropriate temperature.
- Pressure rollers: Apply pressure to ensure the sealing material adheres tightly to the blister.
- Cooling system: Rapidly cools the sealed package.
- Tension control device: Controls the tension of the sealing material to avoid wrinkling or excessive stretching.

You need to adjust the sealing temperature, pressure, and time according to different packaging materials and product characteristics to ensure optimal sealing effects.

 

 

5. Punching Station

The punching station is responsible for cutting the continuous blister packaging into individual or multiple unit packages. This process requires a high degree of precision to ensure the integrity of each packaging unit. The main components include:

- Punching mold: Cuts the blisters according to the packaging design.
- Pressure device: Provides sufficient force for clear cutting.
- Waste collection system: Collects and processes waste generated during the cutting process.
- Positioning system: Ensures the accuracy of each cut position.

You can replace the punching molds according to different packaging designs, but be sure to maintain the sharpness and precision of the molds to obtain clean-cut edges.

 

6. Output System

The output system is responsible for conveying the completed blister packages out of the machine and preparing them for subsequent packaging or storage. The main components include:

- Conveyor belt: Transports the cut blister packages out of the machine.
- Sorting device: Classifies packages according to preset conditions.
- Stacking device: Neatly stacks packages for subsequent handling.
- Counting system: Records the number of packages produced.

You can choose suitable output methods according to the production line's needs, such as direct conveying to a cartoning machine or manual packaging area.

 

7. Control System

The control system is the "brain" of the blister packing machine, coordinating the work of each part to ensure the smooth progress of the entire packaging process. The main components include:

- PLC (Programmable Logic Controller): Controls the operation of the entire machine.
- Touch screen interface: Allows operators to easily monitor and adjust parameters.
- Sensor network: Monitors the operating status of various parts of the machine in real-time.
- Safety system: Quickly stops the machine in case of abnormalities to protect operators and equipment.

You need to be familiar with the operation of the control system to quickly adjust parameters to meet different production requirements.

 

 

8. Auxiliary Systems

Although auxiliary systems do not directly participate in the packaging process, they are crucial for ensuring the normal operation of the equipment and product quality. The main components include:

- Pneumatic system: Provides compressed air for various components.
- Vacuum system: Used for forming and product fixation.
- Cooling system: Controls the temperature of equipment and products.
- Lubrication system: Ensures smooth operation of mechanical parts.

You need to regularly check and maintain these auxiliary systems to ensure the stable operation of the entire equipment.

 

9. Quality Control System

The quality control system runs throughout the entire packaging process, ensuring product quality at every stage. The main components include:

- Visual inspection system: Checks product integrity and packaging quality.
- Weight detection device: Ensures each package meets weight standards.
- Seal inspection: Checks the integrity of blister seals.
- Rejection system: Automatically removes non-conforming packages.

You can adjust the parameters of the quality control system according to product characteristics and quality requirements to achieve optimal detection results.

 

10. Cleaning System

The cleaning system ensures hygiene and safety throughout the packaging process, which is particularly important. The main components include:

- Dust removal device: Removes dust and particles from the air.
- UV sterilization lamp: Sterilizes packaging materials and products.
- Automatic cleaning device: Periodically cleans key components.
- Waste collection system: Collects and processes waste generated during production.

You need to establish strict cleaning procedures and ensure that operators follow them rigorously to maintain a high standard production environment.
