Fully-auto Sleeve Sealer & Shrink Tunnel (Multi-rows)

Key Features:

• High-Precision Material Recognition and Positioning: Equipped with imported photoelectric sensors, the system accurately detects and identifies the position of materials. Working in conjunction with the mechanical structure, it automatically aligns and groups products into multiple rows, reducing the need for manual sorting and placement and lowering labor costs. There is no need for frequent mold changes; different multi-row packaging modes can be selected directly on the touchscreen to accommodate a variety of packaging quantities.
• Mechatronic Intelligent Control System: Utilizing a PLC paired with a touchscreen HMI, the system enables coordinated operation of mechanical, electrical, and pneumatic components. Operators can directly access different packaging programs via the interface, and the system includes a built-in production counting and statistics function, allowing factories to record production capacity data in real time. Core components throughout the machine are sourced from leading global brands, ensuring a low failure rate; component configurations can also be flexibly adjusted to meet customer budgets.
• Smooth Belt-Type Feed Conveyor: The feed station employs a belt conveyor structure, ensuring fast and stable material transport while minimizing the risk of scratches or impacts on the surfaces of boxes and bottles. The equipment can be optionally equipped with a color film positioning system to ensure precise alignment and wrapping of heat-shrink film with printed patterns, meeting the higher aesthetic packaging standards required for branded products.
• Coordinated and Stable Sealing, Cutting, and Shrinking Output: The specialized cross-cutting and sealing blade features high-temperature resistance and anti-adhesion properties, ensuring strong seal seams during high-speed continuous production and reducing defect rates caused by seam cracking. The conveying speeds of the sealing and cutting unit and the shrink tunnel can be adjusted independently. The spacious chamber ensures thorough and uniform hot air circulation, allowing the PE film to heat evenly and resulting in flat, snugly fitted finished packaging.
• Flexible production line adaptability: The system can be configured with a curved feed assembly to adapt to the existing layout of the production line, eliminating the need for major modifications to the current assembly line. The working heights of the main unit and the shrink tunnel are standardized, facilitating seamless integration with upstream feeding equipment and downstream case packing and palletizing equipment. It can be integrated into fully automated production lines for unmanned operation or used as a standalone machine with manual loading.
• Reduced packaging material consumption: Multiple items can be bundled together without the need for paper trays, eliminating the costs associated with purchasing and storing paper trays. This optimizes the company’s overall packaging costs while ensuring effective bundling and dust protection.

Applications:

Widely used for bottom-tray-free shrink packaging of square boxes and round bottles—such as food gift boxes, medicine boxes, cosmetic packaging, bottled beverages, and bottled personal care products—supporting both single-row and multi-row combination packaging. Suitable for back-end packaging processes in food processing plants, pharmaceutical companies, and personal care production facilities, it can be integrated into fully automated production lines for high-volume production or operated in manual loading mode to fulfill small- to medium-sized batch orders.
