The discharge mechanism 90 is used for storing the sheared reinforcing bars 100 for storage or subsequent processing. Optionally, the discharge mechanism includes a discharge shelf for storing the severed rebar 100.

In addition, the reinforcing steel bar cold rolling straightening production line of the embodiment further includes a control mechanism, and the control mechanism is electrically connected to the pay-off mechanism 60, the phosphorus removal mechanism 110, the powdering mechanism 120, the cold rolling mechanism 10, the drawing mechanism 70, the traction mechanism 20, the counting mechanism 80, the straightening mechanism 30, the supporting mechanism 40, the flying shear mechanism 50, and the discharging mechanism 90, respectively, so as to control the start and stop cooperation of each mechanism.
