The utility model relates to the technical field of PVC (polyvinyl chloride) boards, in particular to a PVC board feeding device with a positioning structure, which comprises a positioning support seat, a driving roller, a driven roller and a transmission belt, the positioning support seat is of a U-shaped structure, the driving roller is rotatably mounted in the positioning support seat, and the driven roller is rotatably mounted in the positioning support seat. Driven rollers are rotationally arranged in the positioning supporting seat at equal intervals, and a transmission belt is connected between the driving roller and the driven rollers. According to the PVC plate feeding device with the positioning structure, through the design that the detachable extension plate is arranged at the upper end of the baffle of the mechanism assembly, when the extension plate is installed, the overall height of the baffle is increased, the conveying requirement of large-batch PVC plates is met, and when the extension plate is detached, the height of the baffle is not changed, and the conveying requirement of conventional batch PVC plates is met; by means of the design, the height of the baffle can be automatically adjusted according to the number and specification of the plates, and the limitation that a traditional device cannot flexibly adapt to different numbers of plates is effectively solved.
