Capsule operating mechanism of tyre vulcanizer

Abstract

The invention provides a capsule operating mechanism of a tyre vulcanizer. The capsule operating mechanism is characterized in that: the capsule operating mechanism comprises a capsule, a capsule cylinder, an upper clamp ring, a lower clamp ring and steam conduits; an accommodation space for accommodating the capsule is arranged in the capsule cylinder, the top surface of the capsule cylinder is provided with an opening communicated with the accommodation space, the upper clamp ring is used for fixing the upper end of the capsule, the lower clamp ring is used for fixing the lower end of the capsule, and the steam conduits are communicated with the capsule; the capsule is contracted in the accommodation space in the capsule cylinder before the capsule operating mechanism is used; the upper clamp rang and the lower clamp ring simultaneously drive the capsule to depart from the accommodation space to a preset height and the capsule is aerated by the steam conduits when the capsule operating mechanism is used; and the upper clamp ring and the lower clamp ring simultaneously drive the lower end of the capsule to contract to the accommodation space and a gas in the capsule is exhausted by the steam conduits after the capsule operating mechanism is used. The invention aims to provide the capsule operating mechanism which has the functions of independent upper clamp ring elevation, independent lower clamp ring elevation, independent steel ring elevation, rapid capsule changing and the like, and can independently complete all functions of three parts of an ejector, a jig and the like of an original RIB (rolling in bladder) type capsule operating mechanism.

Description

technical field [0001] The invention belongs to the field of tire vulcanization machinery, and in particular relates to a bladder control mechanism of a tire vulcanizer, in particular to a RIB type bladder control mechanism. Background technique [0002] The modern tire shaping and vulcanizing machine is a highly automated equipment that combines the functions of tire shaping and vulcanization. RIB (Rolling In Bladder) refers to the roll-in bladder type. The RIB bladder operating mechanism is used to install the bladder and make the bladder enter the tire embryo. The inner cavity and the inner cavity of the finished tire are pulled out and the vulcanization medium enters and exits the bladder. The commonly used RIB capsule operating mechanism is installed in the inner cavity of the base, and is positioned by the stop on the lower heating plate. Different shaping heights can be adjusted by replacing the shaping sleeve in this mechanism. The specific length of the shaping slee...
