The 5-ton hydraulic unwinding machine is a commonly used auxiliary equipment for tile pressing machines and cold bending production lines. It relies on hydraulic systems to achieve coil tensioning and unwinding operations, with a compact structure and stable operation. It is mainly used for carrying and feeding metal coils such as color steel coils, galvanized coils, and cold-rolled coils, and is widely suitable for small and medium-sized color steel processing, advertising buckle plates, ordinary purlins and other production lines.

Equipment structure composition

• Host rack: Made of welded national standard steel, with a stable structure and good load-bearing performance, it is not easily deformed during long-term operation.
• Hydraulic tensioning spindle: blade type tensioning structure, hydraulic drive completes core support and contraction, automatic centering, adapted to standard steel coil inner diameter.
• Hydraulic power unit: Integrated hydraulic pump station and oil pipeline, stable output pressure, providing power for tensioning action.
• Material pressing arm device: mechanical/pneumatic material pressing arm, pressing the outer ring of the coil to prevent loose or loose materials during operation and shutdown.
• Braking mechanism: Pneumatic braking device, which quickly locks the coil when stopping to avoid inertia rolling.
• Guiding roller: assists in supporting the sheet metal, ensuring straight feeding and reducing sheet metal deviation and bending problems.
• Operating components: Simple control buttons that control hydraulic tension, contraction, and brake start stop, with intuitive operation.

Core advantages

• Hydraulic tensioning, firm centering: Hydraulic blade type tensioning, uniform clamping force, high concentricity of the coil, no shaking or deviation during unwinding, and less likely to collapse of the tail material.
• High cost-effectiveness and strong practicality: simple structure, low procurement and usage costs, suitable for small and medium-sized production lines, meeting the needs of conventional coil unwinding.
• Stable operation and protection of the board: The passive unwinding resistance is moderate, and the board is transported smoothly without scratching the surface coating. The appearance quality of the finished product is guaranteed.
• Easy to operate and quick to get started: manual control mode, simple functions, and operators can use it without professional training.
• Easy maintenance: Hydraulic components and seals are universal standard parts, easy to replace, only need to check hydraulic oil and lubricate rotating parts daily, with low operation and maintenance costs.
• Wide adaptability: It can be matched with various equipment such as color steel tile pressing machine, advertising buckle machine, lightweight purlin machine, etc., with strong versatility.

Application scope

• Supporting equipment: single-layer/double-layer tile press, C84 advertising buckle machine, lightweight color steel wall panel/roof panel forming machine, etc.
• Applicable enterprises: small and medium-sized color steel processing plants, advertising decoration material factories, and small steel structure processing households.
• Processing materials: Conventional metal coils such as color steel coils, galvanized coils, and cold-rolled coils weighing 5 tons or less.
