This Automatic Film Overwrapping and Sealing Machine is the ideal choice for manufacturers requiring adaptable, efficient, and user-friendly packaging solutions for high-quality, tamper-evident sealing of boxed products. With its advanced servo system, modular control, and comprehensive safety features, it stands out as a reliable and versatile asset in diverse production environments.
1. Automatic Feeding
In the feeding phase, the machine automatically transports the items to the designated positioning area. This process uses a linear feed design, ensuring stable and orderly movement of items into the packaging workflow, minimizing manual handling and increasing efficiency.
2. Film Feeding and Cutting
The machine draws packaging film from the roll and accurately cuts it to the appropriate length based on product dimensions. Dual servo motors control the film length, allowing for easy adjustments to accommodate different packaging specifications.
3. Film Folding
The machine folds the film around the product, wrapping it entirely. The folding system uses a precision mechanical structure to ensure the film edges are neat and closely aligned with the product surface, enhancing the overall appearance.
4. Heat Sealing
After folding, the heat sealing unit activates to secure the folded edges. The PLC-controlled heat sealing process ensures that the seal is tight without damaging the film, meeting packaging integrity requirements.
5. Edge Folding and Shrinking
Following heat sealing, the machine folds the film edges for a cleaner finish. For specific products, a heat-shrink option can be activated to make the film fit closely to the item, achieving a 3D wrap effect.
6. Finished Product Output
The wrapped products are automatically conveyed to the output section, where they are collected as finished items. The conveyor system is designed to prevent scratching, ensuring that the packaging remains intact and visually appealing. Products can then proceed directly to further inspection or downstream packaging steps.
7. Waste Collection
Excess film from the cutting and folding stages is collected through the waste recovery system, reducing material waste and keeping the workspace clean.
8. Tear Strip and Coding (Optional)
The machine can be equipped with an optional tear-strip and coding device. The tear-strip allows for easy opening of the package, while the coding device can print production dates, batch numbers, and other traceable information on the film.
9. Safety Protection and Fault Alarms
The machine includes multiple safety mechanisms. If issues such as jamming or misfeeds are detected, the machine will automatically stop and alert the operator to ensure safety. The PLC and touchscreen interface provide real-time monitoring and fault diagnostics, making it easy for operators to perform timely maintenance.
