Tread transfer ring of tire building machine

Abstract

The invention discloses a tread transfer ring of a tire building machine. The tread transfer ring comprises a base, a fixed disc and multiple clamping jaws, wherein a driving disc is connected into the fixed disc through a bearing, and is connected with an extension structure mounted outside the fixed disc through a bracket; the clamping jaws are mounted on the inner ring of the driving disc, and fit the disc wall of the driving disc through a clamping jaw bracket; the clamping jaw bracket penetrates through the disc wall of the driving disc, and is connected with a slide rail 1 mounted on the fixed disc through a shaft; and the shaft is connected with the driving disc through a slide rail 2. The tread transfer ring overcomes the defects in the prior art, and is reasonable in design structure; the driving disc capable of rotating is arranged in the fixed disc, and is driven to rotate through the extension structure; and when the driving disc rotates, the slide rail 2 is driven to move so as to drive the clamping jaw bracket and the clamping jaws to perform a radial motion along the slide rail 1. The extension and the shrinkage of a cylinder are controlled through a servo motor.

Description

technical field [0001] The invention relates to the technical field of rubber machinery, in particular to a tread transfer ring of a tire building machine. Background technique [0002] The tread is an important component of the all-steel radial tire. On the all-steel radial tire building machine, the tread parts on the belt drum are removed by the tread transfer ring, and then transferred to the building drum accurately. [0003] The clamping work of the existing tread transfer ring is realized through six locking cylinders, that is, the working mode of the locking cylinders is controlled by a delay signal. Because this structure has high requirements on the locking cylinder and signal control, and the locking cylinder failure and maintenance costs are high, resulting in easy deformation / clamping of the tread when clamping (the longer the waiting time, the more obvious the deformation). At the same time, the locking cylinder structure is prone to problems such as inability...

AI Technical Summary

Problems solved by technology

Because this structure has high requirements on the locking cylinder and signal control, and the locking cylinder failure and maintenance costs are high, resulting in easy deformation / clamping of the tread when clamping (the longer the waiting time, the more obvious the deformation)

At the same time, the locking cylinder structure is prone to problems such as inability to lock and inconsistent expansion and contraction speeds of the cylinder, which may cause equipment accidents where the transfer ring collides with the embryo / auxiliary drum.
