Sheet Margarine Packaging Machine

The following figure shows the position and main working process of the sheet margarine packaging machine in the entire sheet margarine packaging machine:

The main components of the sheet margarine packaging machine

A typical sheet margarine packaging machine usually consists of the following four functional modules, which are the technical core of the sheet margarine packaging machine.

1. Fixed-length cutting device

This device is the entry position of the sheet margarine packaging machine, responsible for cutting the continuous oil sticks into uniformly sized sheeted butter blocks.

•      Servo motor drive: The cutting length can be set within the range of 100-350mm, matching the production line's rhythm (usually 16-30 pieces/minute).

•      Temperature-controlled anti-sticking blade: The blade is equipped with heating function to prevent the butter from sticking, ensuring a smooth and clean cut surface.

•      Follow-up cutting function: The cutting knife moves synchronously with the oil stick during the conveying process and completes the cutting, ensuring that the cut surface is perpendicular to the direction of the oil stick's movement. This is the key technology that ensures the uniform weight of each sheet.

•      Vertical deviation control: The vertical deviation of the cut surface from the oil stick's axis ≤ ±2 degrees, laying the foundation for the subsequent folding packaging.

2. Paper supply and initial forming device

After the sheeted butter is cut, it immediately enters the paper supply and initial forming area of the sheet margarine packaging machine.

•      Automatic paper supply and cutting: The equipment automatically supplies and cuts aluminum foil composite paper or sheepskin paper, with the paper size precisely matching the butter block. The sheet margarine packaging machine generally uses aluminum foil paper to effectively block oxygen and light.

•      Forming first and then filling: The machine first presses the packaging paper into an open "small square box", and then pushes the cut butter blocks into it. This is a common design of the sheet margarine packaging machine to improve the packaging speed and regularity.

•      Positioning accuracy: The deviation of the butter block on the packaging paper ≤ ±1mm.

3. Folding and packaging mechanism

Folding and packaging is the core position of the sheet margarine packaging machine, directly determining the appearance of the final product.

•      Multiple mechanical folding: Multiple sets of delicate mechanical guide rods complete actions such as "side folding → top covering → both ends sealing" in sequence, tightly wrapping the butter block into the familiar brick shape.

•      Rotation finishing position: During the folding process, the sheet margarine packaging machine usually sets a rotation mechanism to rotate the butter block 90°, so as to handle the both ends sealing more neatly and make the packaging more beautiful.

•      Adaptive flexibility: The advanced folding mechanism can be adjusted to adapt to different thicknesses (8-30mm) and lengths (100-350mm) of sheeted butter, without frequent mold replacement.

4. Sealing and shaping device

After folding, the sheet margarine packaging machine will perform the final sealing and shaping of the packaging.

•      Heat sealing or pressing: According to the type of packaging material (heat-sealed aluminum foil or cold-sealed paper), the corresponding sealing method is adopted to ensure a firm and good seal.

•      Shape shaping: The butter block after packaging is slightly shaped to make the four corners square and the size consistent (length/packaging deviation ≤ ±1mm).

The conveying and control of the sheet margarine  packaging line

Apart from the sheet margarine  packaging machine itself, the entire sheet margarine  packaging line also relies on the following auxiliary systems to achieve continuous and stable operation:

•      Food-grade conveyor belt: The conveyor belt throughout the sheet margarine  packaging line uses imported food-grade materials to ensure hygiene and safety.

•      Alcohol automatic cleaning system: The scraper is closely attached to the conveyor belt and cleaned with alcohol to prevent residual butter from contaminating. This is the hygiene guarantee for the sheet margarine  packaging line to achieve long-term continuous production.

•      PLC intelligent control system: The operating parameters, fault diagnosis, and automatic counting of the sheet margarine  packaging machine and the entire sheet margarine  packaging line are all managed by the PLC system, enabling fully automated operation.

•      Dynamic detection and rejection: Integrated with a dynamic weighing scale and a metal detector, it automatically rejects products with unquality weight or containing foreign substances， ensuring the qualified rate of the sheet margarine  packaging line's finished products.

When choosing a suitable sheet margarine  packaging machine for your sheet margarine  packaging line， it is recommended to focus on the following points：

1. Speed matching： Ensure that the processing speed of the sheet margarine  packaging machine matches the discharge capacity of the upstream stop pipe to avoid material accumulation or material shortage.

2. Specification range： Confirm whether the adjustable thickness (8-30mm) and length (100-350mm) of the sheet margarine  packaging machine cover all your product lines.

3. Rapid changeability： If you produce multiple specifications of tablet butter， prioritize choosing a sheet margarine  packaging machine with rapid changeability to reduce downtime.

4. Hygiene design： The equipment of the sheet margarine  packaging line should be easy to disassemble and clean， with a smooth body without dead corners. Features such as alcohol scraper cleaning are very helpful for long-term stable production.

5. Line integration capability： Choose an experienced supplier to ensure that the sheet margarine  packaging machine can seamlessly connect with the upstream stop pipe， downstream detection， stacking and packaging equipment， forming a complete sheet margarine  packaging line.
