Belted layer transferring ring

Abstract

The invention provides a belted layer transferring ring. The belted layer transferring ring comprises a fixed disc, a driving disc, clamping claw brackets, clamping claws and an air cylinder, wherein one end of the air cylinder is fixed on a base, and the other end of the air cylinder is fixed on the driving disc to be used for driving the driving disc to rotate back and forth; and the driving disc drives the clamping claw brackets and the clamping claws to retract along the radial direction by using a connection rod mechanism. According to the belted layer transferring ring with the structure, the clamping claws can move synchronously; and meanwhile, the coplanarity of the end faces of the clamping claws is guaranteed, the transferring precision of a belted layer and a crown is improved, and the tire forming quality is guaranteed. Furthermore, the quantity of magnetic switches on the air cylinder is increased, so that the accuracy and safety of the air cylinder are guaranteed; one air cylinder is used, so that the cost is saved; and meanwhile, the structures of the clamping claws are improved, and the replacement speeds of the clamping claws with different specifications are improved, so that the time is saved.

Description

technical field [0001] The invention belongs to the field of rubber machinery, and in particular relates to a belt transfer ring for manufacturing tire blanks. Background technique [0002] In the tire blank manufacturing device and process method, the belt transfer ring is an important part of the tire building machine, and its main function is to transfer the ready-fit belt and tread on the belt drum to the building drum for completion. In the forming process, tire unloading tooling can also be added on the belt transfer ring to complete tire unloading. In practical applications, the synchronization, coaxiality, and coplanarity of the end faces of the clamping claws on the belt transfer ring will have a greater impact on the transfer accuracy and molding accuracy of the crown. [0003] The main structure reference of the existing belt layer transfer ring figure 1 , including cylinders, clamping claws, transfer rings and safety edges, etc., 11 sets of clamping claws are d...

Problems solved by technology

[0004] The present invention aims to solve the problem that it is difficult to realize the synchronous movement of the clamping claws of the existing belt layer transfer ring, and the state of the magnetic steel stretched out cannot be detected, which causes misoperation and causes the forming drum to easily collide with the clamping claws when rotating, and proposes a The technical scheme of the new belt transfer ring is as follows:
