Liquid Paste Packaging Machine, Vertical Back-Seal Bag, Four-Side Seal Bag, Pillow Bag, Roll Film Packaging Machine

The butter vertical packaging machine is a specialized application of vertical automatic packaging machines. It is designed for packaging oil and fat products that are solid or semi-solid at room temperature (such as butter, cheese, margarine, and condiment pastes). Its core feature is that the forming, filling, and sealing processes are all completed vertically, making it ideal for packaging bulk, granular, and sauce-like products.

1. Working Principle

Film Roll Installation and Pulling: A roll of packaging film (such as composite film or aluminum foil) is installed on the machine and smoothly pulled out by a pulling mechanism.

Forming: The film passes through a key former and is rolled into a tube.

Longitudinal Sealing: The longitudinal seam of the tube film is sealed by a heat-sealing device, forming a continuous tube.

Film Pulling and Positioning: A film pulling motor (typically a servo motor or stepper motor) precisely pulls the film downward a distance equal to the bag length.

Horizontal Sealing and Cutting: When the film reaches the predetermined position, the horizontal sealing device performs two simultaneous actions:

Seals the top of the current bag.

Seals the bottom of the next bag.

Then cuts the film between the two seals, separating the individual bags.

Metering and Filling: This is a critical step in butter packaging. During the intervals between the horizontal sealing device's operation, a metering system located above the machine fills a measured amount of butter into the formed bags via a hopper. Common metering methods include:

Piston Metering: The most commonly used method uses the piston movement of a pneumatic cylinder to pump and eject a fixed volume of butter. It offers high precision and is suitable for viscous materials.

Screw Metering: Suitable for powders and fine particles, it can also be used for butter, but it is necessary to prevent oil from sticking.

2. Key Features and Advantages

High Efficiency: With a high degree of automation, packaging speeds can reach dozens to hundreds of bags per minute, far exceeding manual packaging.

High Precision: Utilizing a sophisticated metering device and servo control system, each bag of butter is guaranteed to have a consistent weight.

Attractive Packaging: Uniform bag shapes, neat and secure seals, and precise pattern alignment enhance product quality.

Hygiene and Safety: The equipment is primarily constructed of stainless steel, making it easy to clean and meeting food hygiene standards. Aseptic or semi-aseptic packaging is possible.

Flexibility: By replacing the former and adjusting parameters, the machine can accommodate packaging of varying sizes and shapes (e.g., back-seal, three-side seal, four-side seal).

Material Savings: Using roll film reduces material costs compared to pre-made bags and reduces storage space.

3. Applications

Dairy Industry: Butter, cheese, cream, sour cream, etc.

Bakery Industry: Margarine, shortening, jam, fillings, etc.
