Manufacturing: The 10T or higher-capacity unwinding machine is designed to support steel coils and facilitate coil unwinding. It consists of a wire-diameter rail base, an expandable and retractable winding drum, hydraulic cylinders and rotary joints, three-axis rotation mechanism, a servo-motor-driven power and transmission system, pneumatic disc brakes, and a coil-unwinding clamping arm assembly. During initial coil unwinding and threading, the machine operates in active unwinding mode; under normal operation, it can switch between automatic unwinding or counter-tension unwinding modes, making it suitable for processing various types of sheet materials. The pressure roller can firmly clamp the material end, and after cutting through the packaging straps, it can rotate freely, facilitating the expansion, contraction, and movement of the unwinding machine. Advantages: The entire production line features high speed, smooth operation, and exceptional stability.

Manufacturing of the feed clamp conveyor (with a five-roller leveling device): polyurethane clamp rollers, five sets of leveling rollers, plate head leveling for plates thicker than 2.0 mm, controlled by servo motors. Advantages: Protects the plate surface from scratches and ensures stable operation at high speeds.

Manufacturing of the Slitting and Shearing Main Machine (with Dual Knife Holders): The disc shear consists of several components, including the main body, the power unit, and the base. The lower knife shaft is fixed. The upper knife shaft uses copper-block turbine rods for precise and accurate vertical movement. The knife holder frame is driven by a servo motor and leadscrew for smooth and controlled motion. By using spacer sleeves to arrange the knives, slitting specifications can be freely configured according to specific requirements.

Flat Tension Station Manufacturing: The flat tension station consists of upper and lower clamping devices, a slitting shear machine, guiding rollers, and a base. The separating shafts pre-divide the coil material to prevent overlapping; the tensioner adjusts the winding tension to ensure neat and orderly coiling.

Belt Tension Station Manufacturing: High-wear-resistant, low-elongation polyurethane or rubber synchronous belts are selected. The pulleys feature an anti-slip tread design to ensure sufficient transmission friction. Equipped with screw rod or cylinder-type adjustment components, the system achieves a precision of ±0.5 N, enabling fine-tuning of belt tension and rapid locking, thus accommodating various belt material requirements. The frame is constructed from welded steel plates, subjected to aging treatment to relieve internal stresses, and fitted with dust covers and safety guards, striking a balance between rigidity and operational safety. The tension station is connected to the main drive system of the slitting machine via a coupling or synchronous pulley, ensuring a speed synchronization error of no more than 1% and preventing uneven stretching of the belt material.

Seamless Reel Winding Machine Manufacturing: The machine is constructed using No. 45 steel that has undergone tempering treatment, with the surface finished via chrome plating or nitriding (hardness ≥ HRC50) to ensure wear resistance and deformation resistance. The shaft features a pneumatic expansion design with an expansion accuracy of ±0.1 mm, guaranteeing secure core fixation and convenient loading and unloading. Precision Control of the Drive System: The drive system is equipped with a servo motor paired with a planetary gearbox, achieving a transmission ratio error of no more than 0.02%. A ball screw transmission is employed, ensuring a winding speed response time of ≤0.1 s and enabling real-time synchronization with the slitting machine’s cutting speed. Frame and Balancing Structure: The frame adopts a box-type welded structure, subjected to vibration aging to relieve internal stresses, with a deflection of ≤0.2 mm/m. It is fitted with a hydraulic balancing device to ensure uniform force distribution on the winding shaft during the winding process, thereby preventing tilting of the material end faces.

Electrical System: The system includes one main operator console, one auxiliary unwinding console, and one auxiliary stacking console. The entire line adopts centralized control. The main operator console features a 10-inch digital display, functions for adjusting high and low speeds, manual feed, continuous cutting, and fault alarms. The speed-control system’s programmable logic controller (PLC) is a product of Siemens. Electrical control components are either imported products or joint-venture products of comparable quality. Standard electrical cabinets, the main control console, auxiliary control consoles, push-button boxes, detection devices, as well as cables and wires are also included. A touch screen interface allows for convenient switching between manual, single-cycle, and automatic modes, and enables real-time monitoring of the operational status of each component, ensuring safe and efficient operation of the production line.
