The 5-ton fully automatic unwinding machine (with a trolley) is the core supporting equipment of the tile press/cold bending production line. It is designed to provide automatic feeding, hydraulic tensioning, and constant speed unwinding functions for metal coils such as color steel coils, galvanized coils, and cold-rolled coils, solving the pain points of manual feeding, coil deviation, and unstable unwinding. It is widely applicable to various tile forming production lines such as C/Z steel, glazed tiles, wall panels, and buckle plates.

Equipment structure composition

• Host rack: thickened steel welding, stress relief during aging, strong load-bearing capacity, and no deformation during operation.
• Hydraulic tensioning spindle: 4 sets of blade type slider structure, hydraulic driven automatic centering tensioning, suitable for different inner diameter coils, and the tail material does not collapse.
• Power drive system: variable frequency motor+reducer, smooth transmission, speed synchronized with the pressure bearing host, anti pulling and anti deviation.
• Hydraulic feeding trolley: independent hydraulic station, dual power lifting and walking, one click automatic alignment with the core, replacing manual feeding by crane, safe and efficient.
• Material arm device: pneumatic/hydraulic pressure arm, presses the outer ring of the coil to prevent it from unwinding or loosening at high speed.
• Induction control system: Roller type ultrasonic sensor, real-time detection of material level, automatic start stop, speed regulation, to avoid material stacking or breakage.
• Electronic control system: independent control cabinet, button/touch screen operation, Chinese and English interface, parameter memory, fault alarm, zero foundation to learn.
• Brake protection: Pneumatic emergency brake+electromagnetic brake, locks the coil in place at the moment of shutdown to prevent inertial unwinding.

Core advantages

• Fully automatic feeding, saving manpower and effort: equipped with a hydraulic trolley, one click automatic lifting, walking, and hole alignment. The 5-ton coil material does not require manual lifting by a crane, and can be operated by one person, greatly reducing labor intensity and safety risks.
• Hydraulic tensioning, precise centering: automatic centering tensioning, high concentricity of the coil, no deviation or shaking during unwinding, suitable for thin/thick plates, high utilization rate of tailings.
• Variable frequency synchronization, stable unwinding: stepless speed regulation linked with the tile pressing host, constant tension unwinding, no stretching or wrinkling of the board, ensuring subsequent forming accuracy.
• Safe protection and reliable operation: anti rolling of the pressing arm, automatic start stop induction, emergency braking, multiple safety protections, suitable for long-term continuous production.
• Strong adaptability and wide universality: compatible with 508/610mm inner diameter coils, suitable for 0.3-1.5mm thickness and ≤ 1250mm width, can be matched with various tile pressing machines and cold bending production lines.
• Durable and easy to maintain, low cost: key components are quenched for wear resistance and durability; Hydraulic/electrical components are standard parts, easy to purchase and replace, only require regular lubrication for daily use, and have low maintenance costs.

Performance characteristics

• Fully automated process: loading → tightening → unwinding → induction speed regulation → shutdown, fully automated, reducing manual intervention.
• Stable structure: thickened frame+solid spindle, strong load-bearing capacity, long-term operation without shaking or deformation.
• Constant tension: frequency conversion+induction control, stable unwinding tension, flat board without scratches or deformation.
• Easy to operate: independent electrical control cabinet, button based operation, simple mode switching, easy for beginners to get started quickly.
• Efficient and energy-saving: variable frequency drive, on-demand speed regulation, low energy consumption; The feeding efficiency is more than three times higher than manual labor.
