Fully-auto Vertical Sleece Sealer & Shrink Tunnel (Linear Type）

Key Features:

• High-Temperature-Resistant Metal Chain Conveyor: The entire machine uses metal chain plates as the conveying medium, which can withstand the high-temperature environment of the heat shrink chamber. Workpieces are fed steadily into the shrink oven, eliminating the issues associated with conventional belts—such as heat-induced aging, deformation, and flaking that can contaminate products—making it suitable for long-term, continuous industrial production.
• Vertical Dual-Reel Film Configuration: The film frame features a vertical dual-reel layout, maximizing space utilization. It supports large-size film reels, reducing the frequency of film changes and increasing the production line’s effective operating time. Film reel installation, removal, and maintenance are simple, making it easier for operators to perform film changes.
• Dual-Mode Feeding for Automated Applications: The feeding and unloading system supports two operating modes—workpieces can be manually placed for loading and unloading, or the system can be integrated with robotic arms for fully automated loading and unloading. This design accommodates both small- to medium-batch manual production and large-scale unmanned assembly line requirements.
• Anti-adhesive Coated Vertical Sealing and Cutting Blade: The blade surface undergoes a special coating treatment that effectively prevents weld residue from adhering to the blade during high-temperature film welding and cutting. This reduces film adhesion failures, maintains stable cutting performance during prolonged continuous operation, and minimizes the frequency of cleaning and maintenance.
• Dual Safety Protection Mechanism: An integrated dual-safety protection system combining sensor detection and mold positioning identifies the workpiece’s location during the sealing and cutting process, preventing accidental damage to valuable and precision components and reducing the risk of production scrap for high-value workpieces.
• Compact, Linear Machine Layout: Featuring a straight-in, straight-out structure with a clear material flow path, the machine has a compact overall width, simplifying production line layout in the workshop. It can be directly integrated into existing assembly lines without requiring major modifications to the workshop layout.

Applications:

Widely used for POF heat-shrink packaging of cylindrical and ring-shaped upright workpieces, such as sealing rings, rubber hoses, tape rolls, ring-shaped hardware components, and coils; suitable for rubber product manufacturers, automotive parts factories, and tape manufacturers. It can operate as a standalone machine with manual loading, or be integrated with robotic arms and upstream processing equipment to build a fully automated post-processing packaging production line.
