The invention discloses a tray recovery component of a magnetism isolating rod tray feed mechanism. The tray recovery component of the magnetism isolating rod tray feed mechanism comprises a sliding plate, wherein a vertical connecting plate perpendicular to the sliding plate is fixed on the upper plane of the sliding plate via a reinforcing rib; a transverse mounting plate is fixed on the upper end face of the vertical connecting plate via a reinforcing rib; a recovery lifting air cylinder is fixed on the lower end face of the transverse mounting plate via an air cylinder fixing element; a piston rod of the recovery lifting air cylinder penetrates through the transverse mounting plate; a recovery lifting plate is fixed at the upper end of the piston rod via an air cylinder connecting element; two lifting guide posts are fixed on the lower end face of the recovery lifting plate via a guide post bearing; guide oil jackets are mounted on the transverse mounting plate and located on the two sides of the piston rod of the recovery lifting air cylinder; the two lifting guide posts penetrate through the guide oil jackets corresponding to the lifting guide posts on the transverse mounting plate; and a recovery connecting plate perpendicular to the recovery lifting plate is fixed on the upper end face of the recovery lifting plate via a reinforcing rib. With the adoption of the mode, the component is convenient to operate, recycles a tray and has high working efficiency.
