Title:
SINGLE-SCREW SERVO TURN-UP MECHANICAL BUILDING DRUM
Document Type and Number:
WIPO Patent Application WO/2022/121785
Kind Code:
A1
Abstract:
Disclosed is a single-screw servo turn-up mechanical building drum, mainly comprising side drums, a hollow main shaft, a screw, a servo motor, nuts, connecting keys, turn-up rod sets, positioning devices, and locking devices. The positioning devices are designed with two structures and can achieve locking between the turn-up rod sets and the side drums, the locking devices can achieve locking between the side drums and the hollow main shaft, and the flat width adjustment and turn-up operation of an unvulcanized tire can be completed by adjusting the locking states of the positioning devices and the locking devices. Moreover, the positioning devices have a compact structure, achieve stable locking, and have a self-centering effect, and can compensate for the accumulated movement error of a servo system in the process of driving turn-up rods to perform turn-up operation; the locking devices cleverly utilize the magnifying effect of three-stage inclined wedges on the force to hold bearing shells on the hollow main shaft to achieve the locking of the side drums and the hollow main shaft, and the locking devices have a compact structure, are simple to implement, are easy to maintain, and achieve locking stable.
