2, Composition of production line equipment
This production line consists of an unwinding machine, a leveling machine, a shear butt welding machine, a horizontal sleeve, a forming and sizing machine, a solid-state high-frequency welding machine, an online weld eddy current inspection, a hot cutting saw, a flat head machine, a hydraulic press, an output raceway, and a control system.
1. Uncoiler machine
Machine body and drum, pressure roller device, head finding drive device, shovel head straight head device, braking system, hydraulic system, stop roll device, and control panel.
Working principle and characteristics of the equipment:
The uncoiler is used to support the coil and provide raw materials for the production line.
The structure adopts an active unwinding cantilever drum with hydraulic four-bar linkage expansion and contraction form. The pressure roller is driven by a hydraulic motor, which can achieve active and passive functions, such as finding the head and preventing loose rolls; The straight head function of the shovel head is achieved by a hydraulic cylinder; Equipped with a leading straightening and pressing roller device; Roll up anti loosening device; Rolling inertia braking damping device; The roll blocking device uses end face roll blocking to prevent loose rolls; The hydraulic system and electronic control operating system can achieve up and down unwinding.
