Automatic centering device of belted layer of tyre building machine

Abstract

The invention discloses an automatic centering device of a belted layer of a tyre building machine. The automatic centering device comprises left and right guide plates arranged above a feeding rack, wherein the left guide plate is fixedly provided with a left splint; an automatic centering device is additionally arranged at a feeding head part close to a belt drum; shaking hand wheel causes a screw rod to rotate to push the right guide plate at one side to move; a synchronous belt is driven by the splint to cause a left guide roll to simultaneously move toward the opposite direction, so that the distance between two rows of rolls is close to the width of the belted layer; and a cylinder shaft extends out to push the guide plates to move within a narrow range. After the belt material contact the belt drum, a photoelectric sensor sends out an electrical signal to control the cylinder shaft to retract; and the left and right guide plates clamp and center materials, thereby achieving an automatic centering function. The center of the mechanism deviates from the center of the drum, a nut is screwed off, a bolt is regulated to cause the whole device to transversely move, and the nut is screwed down after the center is centered, thereby improving the quality of a molded tyre.

Description

technical field [0001] The invention relates to a centering device, in particular to a belt layer automatic centering device of a tire building machine. Background technique [0002] The carcass feeding frame of the molding machine is used to automatically provide the inner liner, cord, sidewall and slit wrap to the carcass drum; the belt layer feeding frame and the tread feeding frame provide four layers to the belt drum respectively. Belt plies and tread fabrics. The main engine mainly completes the lamination, shaping, rolling, and turn-up molding of the carcass material, belt layer material, tire fabric, and pad rubber on each forming drum, and removes the formed tire blank. According to different tire specifications, the width of the belt layer will vary from 80 to 370mm. It is equipped with a mechanical centering device when uncoiling, which can align the centerline of the material with the centerline of the belt drum to ensure the bonding quality. However, after be...

AI Technical Summary

Problems solved by technology

However, after being conveyed by the conveyor belt, or when the width of the belt layer changes, the material may be biased to one side, so that the belt layer cannot be in the middle position when it is attached to the drum, which will affect the quality of the formed tire.
