ZHZ-300 High Speed Shrink Sleeve Label Sealing Machine is specifically designed for folding film materials (such as PET, PVC, etc.) into reel-shaped packaging material.

1. The main motor is a frequency converter motor, utilizing vector inverter for closed-loop control, yielding high-precision speed regulation and ensuring uniform glue application at both low and high speeds.
2. Unwinding tension is controlled by a 2.5kg magnetic powder brake with a tolerance of ±0.5kg.
3. Automatic tension adjustment during acceleration and deceleration, compensating via inertia.
4. EPC unit from Pausource (TAIWAN brand) offers a tracking tolerance of ±, with a maximum tracking speed of 25mm/s and side-to-side adjustment range of ±70mm.
5. Unwinding features a 3-inch air shaft.
6. Traction steel roller (pressure roller) is 90mm in diameter and 320mm in width, with a chromium-plated, precision-machined surface.
7. Traction rubber roller measures 90mm in diameter and 320mm in width, manufactured from polyurethane rubber.
8. Steel roller clutch employs pneumatic cylinders (diameter: 50mm, 20mm stroke) on both sides for simultaneous operation; adjustable pressure.
9. Traction rubber roller operates independently, driven synchronously by a vector inverter motor.
10. Rewinding roller uses a 3-inch batten-type air shaft.
11. Rewinding section is equipped with an independent motor and magnetism-based tension control, delivering low heating and stable, precise tension.
12. Rewinding conicity tension (semi-diameter tension curve; speed-tension curve): automatically stops upon reaching the preset rewinding length or diameter, or when the minimum unwinding diameter is reached.
13. The gluing unit is fitted with a solenoid valve needle valve and a flow metering pump. The pump automatically regulates glue delivery—activating during operation and shutting off when stopped.
15. The center of the machine houses an idle guide roller made from aluminum alloy, hard-anodized (similar to brown guide roller); upon rotation, static balance is ±0.4g; coating specification: Φ30mm–Φ300mm; maximum gluing speed is 300m/min; sealing accuracy: ±0.3mm.
16. Aluminum format plates configure label sizes; different plates available for various label dimensions.
