Production line equipment composition
1. Uncoiling machine
Body and drum, press roller device, screed drive device, shovel head straight head device, brake system, hydraulic system, coil stopping device, operating table.
Equipment working principle and characteristics:
The uncoiler is used to support the tape coil and provide raw materials for the production line.
The structure adopts the form of active uncoiling cantilever drum with hydraulic four-link expansion and contraction. The press roller is driven by hydraulic motor, which can realize active and passive, complete the function of finding and preventing loose coil; The shovel head straight head function is realized by the hydraulic cylinder; Equipped with lead straightening roller device; Coil anti-loosening device; Coil inertial braking damping device; The coil blocking device is end-face coil blocking to prevent loose coil; Hydraulic system and electronic control operating system, can achieve up and down unwinding.
