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

Key Features:

• Automated Multi-Layer, Multi-Row Stacking and Consolidation: Equipped with a lifting stacking cylinder and a lateral material-pushing mechanism, this system automatically stacks and consolidates products in multiple layers and rows according to production processes. It eliminates the need for complex custom molds; the number of products stacked per group can be adjusted simply by setting parameters on the touchscreen. This addresses the pain points of low efficiency and uneven placement associated with manual stacking, while accommodating diverse packaging requirements.
• Anti-adhesion Reinforced Sealing and Cutting Blade Assembly: Utilizes specialized sealing and cutting blades treated with a proprietary process, offering excellent resistance to adhesion and high temperatures. The resulting seals are strong and secure; even during high-speed continuous production, the seals are unlikely to crack. This reduces defects caused by adhesive residue or incomplete seals, ensuring consistent and uniform packaging quality during prolonged mass production.
• Chain-Type Smooth Conveyor System: The feeding station employs a chain conveyor structure with responsive drive mechanisms and smooth material handling. The positioning of stacked boxes during conveyance remains stable, minimizing jams and misalignment issues, and providing a reliable foundation for subsequent film wrapping and sealing operations.
• Customizable Dual-Film-Frame Upgrade: Supports an optional dual-film-frame assembly capable of holding two film rolls. This allows for quick switching when one roll runs out, reducing downtime caused by roll changes and further increasing the effective production time of the entire production line.
• Integrated Mechatronic Control: The speeds of the main unit and the shrink tunnel can be adjusted independently, while the worktable height remains consistent, facilitating seamless integration with upstream and downstream production lines; Core electrical components throughout the machine are sourced from leading brands to ensure stable operation, and component configurations can be adjusted to meet specific customer requirements.
• Fully Enclosed Safety Design: All moving parts are equipped with protective enclosures to prevent accidental contact; the hot-air shrink tunnel features a fully enclosed chamber structure that ensures uniform heat circulation, allowing the PE shrink film to heat evenly and resulting in smooth, snugly fitted packaging.

Applications:

Widely applicable for bottomless, bundled heat-shrink packaging of square boxed products such as food gift boxes, medicine boxes, cosmetics boxes, and stationery packaging boxes. Supports single-layer multi-row or multi-layer stacked packaging. Suitable for back-end packaging processes in food processing plants, pharmaceutical companies, and personal care product factories. It can either integrate with upstream automated production lines to achieve unmanned continuous production or operate as a standalone machine with manual loading, flexibly handling small-to-medium batch orders.
