Abstract

The invention discloses an automatic uncoiler and roller shearing machine speed matching control system which comprises a shearing motor controller, an uncoiling motor controller, a plurality of photoelectric switch sensors and an adder. The shearing motor controller is used for controlling a shearing motor of a shearing machine and has a speed feedback function, the uncoiling motor controller is used for controlling an uncoiling motor of an uncoiler, the photoelectric switch sensors are vertically mounted on the inner wall of a loop pit at intervals, and the adder is connected with output ends of the photoelectric switch sensors; a D/A (digital/analog) conversion circuit is connected with a speed feedback signal output end of the shearing motor controller, and an output end of the D/A conversion circuit is connected with input ends of the photoelectric switch sensors. The automatic uncoiler and roller shearing machine speed matching control system has the advantages that the automatic uncoiler and roller shearing machine speed matching control system is simple in structure, reasonable in design, convenient to implement, popularize and utilize, low in cost and high in adjustment precision, reliability and practicality, the rejection rate and the strip longitudinal shearing production cost can be reduced, the production efficiency can be obviously improved, and a good service effect can be realized.
