Fully-auto Straight Servo Sleeve Sealer & Shrink Tunnel

Key Features:

• Compact, straight-through design, ideal for long products: Features a unique straight-through structure where products are fed in at one end and discharged directly at the other. The product flow does not require directional changes and is not limited by product length. The machine’s compact design allows for easy deployment even in factory settings with limited space, reducing the complexity of production line retrofits.
• Optional Servo Configuration for Mixed-Size Production: A servo-equipped version is available to enable mixed-size production on a single line. When handling packaging orders with multiple product categories and sizes, there is no need to repeatedly stop the machine for manual adjustments; the equipment automatically adapts to size changes, effectively reducing changeover and debugging time while improving overall production line utilization. This makes it ideal for manufacturers with a wide variety of product categories. The standard pneumatic cylinder version achieves a maximum packaging speed of 15 pieces per minute, meeting medium to high production capacity requirements.
• Independent motor-controlled film release system: The film feeding mechanism is equipped with an independent drive motor to control film release. This ensures precise film feeding response and stable film tension. It adjusts the film feed amount based on the actual length of the workpiece, reducing film stretching, deformation, slackness, and wrinkling, thereby minimizing unnecessary film waste.
• High-quality electrical components ensure stable and reliable operation: Core components—including sensors, cylinders, PLCs, touchscreens, temperature controllers, and variable-frequency drives—are all sourced from internationally renowned brands. The mechanical, pneumatic, and electrical systems work in seamless coordination, resulting in a low failure rate during prolonged continuous industrial production; component configurations can be flexibly adjusted to meet specific customer project requirements.
• Large-Chamber Hot-Air Shrink Tunnel: Equipped with a large-capacity hot-air shrink tunnel featuring ample chamber space, independently adjustable conveyor speed, and uniform hot-air circulation. This ensures thorough heating of large or multi-item bundled products, guaranteeing uniform shrinkage of PE heat-shrink film and a neat, aesthetically pleasing finished product appearance.
• Standardized workbench height facilitates integration with upstream and downstream processes: The workbench height of the main unit and the shrink tunnel is uniform, allowing for seamless integration with upstream conveyor lines as well as downstream palletizing and case-packing equipment. This enables either full integration into a fully automated production line for unmanned operation or flexible production as a standalone unit with manual loading.

Applications:

Widely applicable for the collective heat-shrink packaging of bottled product sets, boxed kits, foam-packed items, and various boxed products, covering numerous industries such as personal care, hardware, building materials, consumer goods, and industrial products. It can handle both standard-sized, neatly arranged goods and longer workpieces; it is particularly suitable for scenarios where a single production line in a factory needs to rotate between producing multiple product specifications, enabling bottom-tray-free collective plastic packaging that facilitates the stacking of goods in warehouses and logistics transportation.
