1. The StructureFundamentally, the heavy-duty decoiler machine has a sturdy frame made of regular H-shaped steel, however manufacturers frequently utilize I-beams as well. The frame, which has rounded corners, gives the entire device a strong basis. Carefully welded from steel plates, it has bearing support points that are positioned for maximum longevity. After the welding process, the surface is carefully polished, stress-relieved, and then bearing holes are precisely machined using cutting-edge CNC machinery.
2. The Mechanism of Drive
The motor and worm gear reducer are the driving mechanism's fundamental components, and they are located inside the base enclosure. Smooth and effective operation is ensured by a system of belts and pulleys connected to the shaft, which facilitates power transmission seamlessly.
3. The System of Expansion and Contraction
The heavy-duty decoiler's drum-shaped expansion and contraction mechanism is essential to its operation. It consists of a shaft with a threaded hole on one end and a sliding sleeve covering it. Attached to the end of the sleeve is an adjustment bolt that threads into the threaded aperture. The sleeve is surrounded by rotating rods, each of which has a support tile plate fastened to its opposite end. The shaft is adorned with guide baffles that have waist holes to allow for accurate adjustment. Blocking blocks are used to stiffen the protruding blocks on one end of the support plate so that they do not accidentally shift and line up with the waist holes. By manipulating the adjusting bolt, the support plate's distance from the shaft can be adjusted, providing the best possible adaption to a variety of coil inner diameters.
4. The System of Electrical Control
The electrical control system is located next to the equipment and consists of an electrical control box and, for models larger than 500, an induction frame. Important parts including transformers, time relays, AC contactors, and switch buttons are located inside the control box. Through insulating pads, the induction rod is attached to the heavy material rack's frame discharge port. Induction lines connect the induction rod to the control box. The induction start and stop functions of the machine may be precisely controlled with this arrangement.
