Description
Technical Field
The invention relates to the technical field of tire equipment, in particular to a tire blank centering mechanism.
Background
In the process of vulcanizing the tire by using the vulcanizing machine, a manipulator of the vulcanizing machine places the tire blank on a lower hot plate of the vulcanizing machine, and a hydraulic cylinder drives an upper hot plate and a die sleeve to move downwards to cover the tire blank in the hot plate. Then pressurizing and heating the tire by introducing nitrogen and steam according to the process requirements, continuously promoting the rubber material and various additives to react and form a macromolecular reticular structure, and pressing the tire tread into the patterns of the segmented mold. The manipulator needs to grab the green tire placed on the buffer station and place the green tire on the lower hot plate of the vulcanizing machine, however, before the manipulator grabs the green tire, if the position of the green tire is not correct, that is, the green tire is not aligned with the buffer station, that is, the axis of the green tire and the axis of the buffer station deviate from a different axis, the condition of the different axis includes that the axis of the green tire and the axis of the buffer station are not parallel, and also includes that the axis of the green tire and the axis of the buffer station are parallel but do not coincide. In the former case, the green tire is in an inclined state, and the manipulator does not grasp the green tire correctly, so that the green tire can not be accurately pressed in the die sleeve when being placed on the lower hot plate of the vulcanizing machine, the centering of the green tire and the lower hot plate is not facilitated, and the quality problem is easy to generate; under the latter condition, can cause the child embryo position uncertain before the manipulator snatchs, the manipulator snatchs inaccurately and inconvenient, can not snatch even, causes the not smooth even interrupt of vulcanization production line.
