Automatic rubberizing device for inner ring rubberizing machine

The invention discloses an automatic rubberizing device for an inner ring rubberizing machine, which comprises a connecting seat arranged on a rack, and the connecting seat is provided with a rubberizing head capable of lifting to extend into a workpiece inner ring or far away from the workpiece inner ring; and the adhesive tape sticking head is connected with a rotary drive and an adhesive tape sticking drive, wherein the rotary drive can drive the adhesive tape sticking head to rotate around the outer wall of the adhesive tape sticking head, and the adhesive tape sticking drive drives the diameter of the adhesive tape sticking head to be increased in the workpiece ring so that the adhesive tape surrounding the periphery of the adhesive tape sticking head can be stuck to the inner ring of the workpiece. The diameter of the rubberizing head is increased through rubberizing driving, the adhesive tape which surrounds the outer surface of the rubberizing head and is sticky on the surface of the inner ring of the
