Servo rapid feeding and waste discharging device for shearing

The servo rapid feeding and waste discharging device for shearing comprises a connecting support, a servo motor is installed on the connecting support through a machine base, an output shaft of the servo motor is fixedly connected with a gear, meanwhile, a rack is installed on the gear, an air cylinder is installed on the upper side of the servo motor through a support, and the air cylinder is fixedly connected with the rack. The end, away from the air cylinder, of the first connecting block is hinged to the bottom of the rotary connecting block. According to the servo rapid feeding and waste discharging device for shearing, after shearing work is completed, a conveying belt supporting roller downwards abuts against a tensioning conveying belt, then a servo motor works to drive the conveying belt to rotate, and machined plates are conveyed to a sorting device; and after conveying of the machined plates is completed, the other motor works to drive the conveying belt frame to do linear motion and rapidly retrea
