The invention discloses an anti-deviation device of a rubber vulcanization conveying belt. The anti-deviation device of the rubber vulcanization conveying belt solves the problem that an existing conveying belt anti-deviation device does not adapt to plane conveying of rubber products. The anti-deviation device of the rubber vulcanization conveying belt comprises a rack, a conveying belt body, twotransmission rollers and two rotating shafts, and is characterized in that the inner side of the conveying belt body is provided with a plurality of ring closed transmission grooves; the two transmission rollers are each provided with transmission protrusions matched with the transmission grooves; a supporting plate is arranged on the inner side of the conveying belt body; a plurality of rows ofupper rolling wheel supports are arranged on the upper surface of the supporting plate; a plurality of upper rolling wheels are rotationally supported on the upper rolling wheel supports in the running direction of the conveying belt; and the upper rolling wheels are matched in the transmission grooves of the conveying belt body. The anti-deviation device of the rubber vulcanization conveying belthas the beneficial effects of being reasonable in design, reliable to use, capable of achieving plane conveying of the rubber products and good in anti-deviation effect.
