Fully-auto Sleeve Sealer & Shrink Tunnel (For Round Wire)

Key Features:

• Dedicated straight-feed conveying structure optimized for circular disk-shaped workpieces: The feeding conveyor mechanism is custom-designed for circular disk-shaped workpieces, ensuring smooth, linear conveyance. This minimizes rolling misalignment during operation, guarantees stable positioning of welding wire spools and wire coils, and provides a reliable foundation for subsequent film wrapping and sealing. The machine’s straight-in, straight-out layout simplifies integration with production lines; it requires no complex turning mechanisms, making it easy to incorporate into existing factory assembly lines.
• Intelligent Inductive Film Feeding Reduces Film Waste: Equipped with inductive film-following logic, the system dispenses the appropriate length of film based on the actual workpiece dimensions, preventing the uncontrolled dispensing of excess film. This effectively reduces PE film waste, lowers long-term production material costs, and improves raw material utilization.
• Seamless integration of sealing, cutting, and shrinking: The sealing and cutting unit is seamlessly integrated with the heat-shrink tunnel. After sealing and cutting, workpieces are smoothly conveyed directly into the oven chamber. The transfer of round trays is smooth, reducing malfunctions such as jams and misalignment, and ensuring the continuity of batch production.
• Compatibility with automated production lines: The machine can be directly connected to upstream winding and reeling equipment to complete the entire process—automatic loading, wrapping, sealing and cutting, heat shrinking, and cooling—enabling unattended operation. It also supports manual feeding as a standalone unit, accommodating both high-volume production lines and flexible production of small to medium batches.
• Stable heat-shrink forming results: The hot air circulation within the heat-shrink tunnel is thorough and uniform, ensuring even heating of the PE heat-shrink film so that even the corners of the reel material shrink fully; immediate cooling and setting after heat shrinkage result in a smooth, tight wrap with a neat appearance, facilitating the stacking and storage of finished products.
• Industrial-Grade System Configuration: The machine’s control system enables coordinated interaction between mechanical, electrical, and pneumatic components. Conveyor speed supports stepless adjustment, allowing flexible adaptation of the operating cycle to accommodate different workpieces and production capacity requirements, making it suitable for long-term, uninterrupted mass production in factories.

Applications:

Primarily used for PE heat-shrink packaging of welding wire reels, copper wire coils, various wire spools, and other circular reel-type workpieces, this machine is widely used in welding material production plants and metal wire processing enterprises. After packaging, it provides moisture-proof and rust-proof protection for reeled welding materials, preventing moisture absorption and oxidation during storage and transportation, while also offering dust protection and impact resistance. The machine can be integrated into fully automated production lines or used as a standalone unit.
