Potato Chip Packaging Machine for Nitrogen-Filled, Vacuum-Effective, Multifunctional Pre-made Bags for Puffed Food

A "pre-made bag potato chip packaging machine" is a very common and critical piece of equipment in the food packaging industry. It refers to an automated machine that uses pre-made, pre-printed bags (i.e., pre-made bags) to weigh, fill, and seal potato chips.

I. What is a pre-made bag potato chip packaging machine?

Unlike a "form-fill-seal" bagging machine, a pre-made bag packaging machine does not manufacture the bags itself. Instead, it uses bags with three or four side seals already produced by a professional bag manufacturer. The advantages of this packaging method are:

Beautiful packaging: Pre-made bags typically utilize high-quality printing techniques (such as gravure printing), resulting in more vibrant and complex designs.

High packaging speed: Because on-site bag making is eliminated, packaging speed is typically higher, making it suitable for large-scale production.

Various bag types: These machines can accommodate a variety of special bag types, including stand-up pouches, zipper bags, and custom-shaped bags.

II. Core Workflow

A typical pre-made bag potato chip packaging machine operates as follows:

Bagging: A robotic arm or suction cup device accurately removes a pre-made bag from the bag storage.

Bag Opening: A clamp grips the bag opening on both sides and opens it using air blowing or suction cups.

Filling: Simultaneously with the bag opening, an upstream multi-head combination weigher accurately weighs the potato chips to a specified weight.

The potato chips are quickly and accurately poured into the opened bag through a filling funnel.

Degassing: Before sealing, the machine removes excess air from the bag through vibration or compression to prevent crushing of the chips during transport and maintain a flat package.

Sealing: A heat sealer heats and pressurizes the bag opening to complete the seal. For zipper bags, the zipper is also sealed first.

Shaping and Output: After sealing, the bag is released and transported via a conveyor belt. It may also pass through cooling and shaping devices to achieve a more crisp appearance.

Inspection and Rejection: Throughout the entire process, a visual inspection system may check whether the bag opening is fully open, the seal is intact, and the date/batch number is legible. Unqualified products are automatically rejected.

III. Main Components of the Equipment

Automatic Bagging Mechanism: Responsible for the stable and high-speed feeding of pre-made bags.

Bag Opening Device: Ensuring reliable bag opening every time is key to efficiency.

Multi-Head Combination Weigher: One of the "brains" of the packaging machine, it utilizes multiple weighing hoppers to achieve high-precision weighing at high speeds.

Filling System: Guides the chips into the bag, reducing debris and dust.

Heat Sealing System: The core actuator, whose temperature, pressure, and time control directly impact seal quality.

PLC Control System: The central nervous system of the entire equipment, coordinating the operation of various components and allowing the operator to set parameters.

Inspection Systems: These systems, such as checkweighers, metal detectors, and visual inspection systems, are used for quality control and product safety.

IV. Key Features and Advantages

High Precision: The combination weigher typically achieves a weighing accuracy of ±0.5-1 gram.

High Efficiency: A wide range of speeds is available, ranging from dozens to hundreds of bags per minute, depending on the number of workstations and the degree of automation.

Flexibility: By replacing the gripper and mold, it can accommodate pre-made bags of varying sizes and shapes.

High Automation: The entire process, from bag removal to finished product delivery, is fully automated, significantly reducing manual labor.

Excellent Shelf Life: A nitrogen flushing system displaces air from the bag before sealing, refilling it with nitrogen to effectively extend the shelf life of the potato chips and prevent them from crushing.
