Straightening is an important link for eliminating residual stress and improving the plate shape, and the process technology of straightening has important influence on the quality of finished products. During straightening production, due to continuous bending deformation of the plate strip, oxide scale scales attached to the surface of the plate strip fall off. And whether scale cinder can be effectively discharged in time directly influences the normal operation of the straightening machine and the surface quality of finished products.

The scale collecting device of the straightening machine common in the market generally adopts a structure that a guide groove is used for telescopic receiving of the scale and a trough is used for swinging and dumping. As shown in fig. 1, the scale collecting apparatus of the prior art straightener includes a horizontally disposed inner fixing bracket 1' installed on the housing. A swinging frame 2 'is hinged on the housing window at the left side of the internal fixed bracket 1'. The swing frame 2 'is hinged with the outer side end of a piston rod of the swing hydraulic oil cylinder 3', the cylinder body of the swing hydraulic oil cylinder 3 'is hinged with the oil cylinder hinge point support 4', and the oil cylinder hinge point support 4 'supports the swing hydraulic oil cylinder 3'. A scrap receiving mechanism is arranged above the swinging frame 2'. The scrap receiving mechanism comprises a receiving groove 5', and the receiving groove 5' is arranged on the chain wheel driving mechanism. The chain wheel driving mechanism comprises a driving motor 6' arranged on the swinging rack 2', a driving chain wheel 7' is arranged on an output shaft of the driving motor 6', driven chain wheels 8' are respectively arranged at two ends of the swinging rack 2', chains 9' are arranged on the driving chain wheel 7' and the two driven chain wheels 8', and a material receiving groove 5' is connected to the chains 9 '.

When scraps are received, a hydraulic oil cavity of the swing hydraulic oil cylinder 3 'presses to enable a piston rod to extend out, the piston rod drives the swing frame 2' to rotate around a hinged point with the memorial archway, after the swing frame 2 'is lifted to a horizontal position from an inclined position, the driving motor 6' rotates forwards to drive the driving chain wheel 7 'to rotate, and the driving chain wheel 7' drives the chain 9 'to move towards the direction of the internal fixed bracket 1'. The chain 9' drives the material receiving groove 5' connected to the chain to move until the material receiving groove 5' moves to the inner fixing bracket 1' and is positioned at the material receiving position, and the scales freely fall into the material receiving groove 5'.

When the machine is inclined, the driving motor 6' rotates reversely to drive the driving chain wheel 7' to rotate reversely, so that the chain 9' moves reversely to drive the material receiving groove 5' to move to a discharging position from a scrap receiving position of the internal fixed bracket 1', then a hydraulic oil cavity of the hydraulic swing oil cylinder 3' presses to retract a piston rod, the swing rack 2' rotates around a hinge point with the memorial archway to descend to an inclined position, and then scales automatically slide into the collecting hopper 10' at the lower part along the inclined material receiving groove 5'.
