CONTACT PRESSURE STABILITY APPARATUS OF TIRE AND CUTTING KNIFE IN TIRE TRIMMING MACHINE

摘要

The present invention relates to a tire trimming equipment for removing the extraction rubber present on the surface of the tire after the tire vulcanization operation, in particular, stabilizing the contact pressure between the tire and the cutting knife when removing the extraction rubber of the tire to reduce equipment trouble and re-trimming In a tire trimming equipment with reduced work, the present invention relates to a device for stabilizing contact pressure between a tire and a cutting knife. ; To this end, the present invention is the tire chucking unit 4 and the tire chucking unit 4, which pulls the tire 2 carried by the conveyor 1 by the elevating cylinder 3, and mounts the chucking operation. Or push cylinder (5), an electromagnet (6) connected between the cylinder (5) and the tire chucking unit (4), a running rail (7) for guiding the movement of the tire chucking unit (4), the tire chuck To the weight chuck 10 and the tire chucking portion 4 connected to the wire 8, which pulls the king portion 4 at a predetermined weight through the wire 8 and contacts the cutting knife 9 with a constant contact pressure. In the tire trimming device comprising a cutting knife (9) for removing the extraction rubber from the surface of the tire (2) rotated by, the anti-rotation assembly (11) is mounted at one end of the tire chucking portion (4) The reverse rotation prevention assembly 11 lifts the latch gear 12 and the latch gear 12. Which has a structure consisting of elevating cylinder 13 and the latch gear horizontal forward horizontal rack gear 15 is provided on 14 to 12 are engaged works.
