Fully-auto Corner Sealer and Shrink Tunnel

This fully-auto Corner Sealer and Shrink Tunnel integrates a four-corner sealing and cutting mechanism with a heat-shrink tunnel, making it a professional all-in-one packaging device designed for small and medium-sized products. The equipment can autonomously complete the entire process, including feeding, bag making, sealing and cutting, corner trimming, waste collection, and heat shrinking, creating a smooth and refined packaging appearance while providing all-around protection for the product. Fully automated operation effectively reduces manual intervention, ensuring consistent packaging quality for every finished product, and is suitable for medium-speed automated production lines.

Key Features:

Formula Mode Changeover: Supports formula selection, allowing for one-click parameter retrieval when switching between different packaging products, making product changeover and debugging convenient and efficient.

Intelligent Size Adjustment: Optional automatic product size adjustment function eliminates the need for repeated manual adjustments, significantly reducing operational difficulty.

Four-Corner Cutting Design: Employs a dedicated four-corner linkage cutting structure, completely solving the "dog ear" wrinkle problem of packaging film, resulting in smooth edges and precise, fast sealing.

Negative Pressure Waste Collection: Equipped with an automatic negative pressure waste suction device, it promptly removes cutting residue, preventing waste from scattering and interfering with the production line, ensuring continuous and smooth operation.

High-Sensitivity Feed Detection: A high-sensitivity sensor is installed at the feed end, coupled with PLC dual logic linkage, ensuring accurate feed positioning even at high speeds.

Multi-Servo Cooperative Control: Core mechanisms such as conveying, cross-cutting, and corner cutting are all driven by independent servo motors, precisely linked with the control system, ensuring high-speed and stable operation of the entire machine.

Dedicated Shrink Tunnel: Equipped with a precision temperature-controlled shrink oven, compatible with cross-linked film materials, allowing the film to tightly adhere to the product, providing dustproof, moisture-proof, and scratch-proof protection.

Comprehensive Safety Protection: The entire machine adopts a steel frame structure, with locks and safety sensors on the doors, and protective components added to the inlet and outlet, protecting operator safety and extending equipment lifespan.

High-Quality Component Configuration: The entire machine uses electrical control, sensing, pneumatic, and transmission components from well-known international brands, ensuring stable performance, low failure rate, and long-term continuous operation.

Ten servo motors are configured to control the coordinate work of the conveyor part the cross cutting knife and corner cutting knife respectively.

Applications: Widely applicable to packaging of snack foods, gift boxes, cosmetics, pharmaceuticals, small digital products, daily necessities, etc., especially suitable for batch packaging of regular boxed and small combined goods. It is the preferred equipment for improving packaging quality and production efficiency of various small and medium-sized automated production lines.
