Understanding the Feeding Methods of Pillow-Type Packaging Machines

In today's society, the demand for food products is continually expanding, leading to the rapid evolution of production equipment and an increase in production speed. The emergence of pillow-type packaging machines has significantly accelerated the pace of light industry production, fulfilling a vast market demand. Let's delve into the various feeding methods employed by pillow-type packaging machines.

1. Push Block Automatic Feeding

Push block automatic feeding utilizes a chain-based conveyor system where blocks are attached to the chain at regular intervals. These blocks automatically advance the products along the conveyor. The speed of material feeding is controlled by adjusting the chain's speed. This feeding method is suitable for packaging materials with regular shapes or moderate weight. It ensures smooth and accurate material feeding, making it ideal for high-speed production. However, there may be gaps between push blocks, which could lead to material jamming for thinner materials.

2. Belt Automatic Feeding

Belt automatic feeding employs a conveyor belt system to transport materials. It often includes sensors for material detection. With servo motors and mechanical controls, this method can automatically adjust for varying product placements, ensuring proper packaging without gaps or misalignment. It offers flexibility, stability, and accuracy, making it suitable for a wide range of material sizes and shapes. However, it's more suitable for packaging materials with lower cleanliness requirements, although food-grade belts can be used for food or hygienically sensitive materials.

3. Film Automatic Feeding (Back Film Feeding)

Film automatic feeding, also known as back film feeding, involves placing products directly onto packaging film. The film then transports the products during packaging. This method requires printed or marked films where products are manually placed between the marks for automated packaging. It is commonly used in pillow-type packaging machines for food products with strict cleanliness requirements. It ensures hygienic packaging, smooth operation, and accuracy, particularly for sticky materials. However, it may have a slower packaging speed compared to the other methods mentioned above.

Each feeding method has its advantages and considerations, catering to different packaging needs based on product characteristics and production requirements. Pillow-type packaging machines play a crucial role in meeting the dynamic demands of modern production environments, offering efficiency and precision in packaging operations.
