Problems solved by technology

[0002] An important step in the tire building process is the front-to-back wrapping process of the tire carcass material, especially in the turn-up process, most of the processes use capsules for turn-up, but because the capsules cannot rotate with the building drum in the past, The carcass material and the capsule are worn due to friction during the molding process, and the proportion of the composition and structure of the capsule is not good, resulting in greater wear and tear of the turned-up capsule during the tire turn-up process, which has a greater impact on the control of production costs. pressure
[0003] In addition, the apex rubber bead ring should be buckled after wrapping and before turning it back. In the traditional buckle ring process, because the buckle ring structure is too simple, the apex rubber wire ring will not be bonded firmly, and it will also cause the buckle ring to be broken. Severely worn components
[0004] In addition, due to the improper manufacturing process and improper material selection of the main shaft of the molding machine and the main shaft of the turn-up device, it is easy to cause premature wear and damage of the main shaft, which increases the production cost

Abstract

The invention relates to a tire turn-up device. The tire turn-up device comprises a forming machine spindle, an outer sleeve device body, a finger-type slice device body, a capsule device body, a buckling ring device body and a locking ring device body. The outer sleeve device body, the finger-type slice device body and the capsule device body are all installed on the forming machine spindle in a sleeving mode, and the outer sleeve device body is located on the outer side of the finger-type slice device body and the outer side of the capsule device body in the radial direction of the forming machine spindle. The buckling ring device body is located on the outer sleeve device body.
