Description

Technical Field

[0001] The present invention relates to the technical field of tire production, and specifically to an automatic tire supporting device for a tire vulcanizer. Background Art

[0002] A tire vulcanizer is a device used in the tire vulcanization process. By heating and applying pressure, the rubber material undergoes chemical cross-linking, enhancing the structural stability and durability of the tire. It is mainly used for the vulcanization of various pneumatic tires and has the characteristics of a compact structure, good rigidity, and uniform stress. In the existing tire production process of a tire vulcanizer, after the tire is vulcanized by the vulcanizer, it needs to be separated from the central mechanism to facilitate grasping the tire with a tire loading and unloading device.

[0003] The existing tire supporting devices of tire vulcanizers generally adopt a hugging arm structure that hugs the outer circumference of the tire. By relying on the frictional force between the hugging arm and the contact surface of the tire outer circumference, the tire can be synchronously lifted during the upward movement of the hugging arm until the tire is separated from the central mechanism, so that the tire can be conveniently removed. However, during this process, since the hugging arm is an arc structure and can only rotate around one point, when facing tires of different specifications, the force application points on the contact surface between the hugging arm and the tire change, resulting in the center of the tire not being consistent with the center of the central mechanism, and the contact surface area is also inconsistent. As a result, during the upward movement of the hugging arm, there may be a situation where the tire cannot be separated from the central mechanism. Therefore, it is necessary to rely on manual labor to separate the tire from the central mechanism, which not only increases the labor intensity of the operator but also affects the tire production efficiency. In order to stably transport tires of different specifications and further improve the tire production efficiency, based on this, an automatic tire supporting device for a tire vulcanizer is now provided, which can eliminate the drawbacks of the existing device.

[0071] The above embodiment discloses an automatic tire supporting device for a tire vulcanizer. Among them, when in use, when the vulcanizer completes the vulcanization operation of the tire, at this time, the first motor 203 is started to drive the first bevel gear 201 to rotate. At the same time, under the meshing drive of the first bevel gear 201, two third bevel gears 2014 drive the lead screw 2013 to rotate. At this time, the connecting sleeve plate 207 slides along the outer wall of the support guide rod 4 under the rotation drive of the lead screw 2013 connected by threads. At the same time, the support sleeve frame 208 slides along the outer walls of the support guide rod 4 and the transmission rotating rod 2012 under the drive of the connecting sleeve plate 207 and is separated from the outer wall of the support plate 5;

[0072] During this process, the transmission drum 206 and the connecting roller 2010 drive the conveyor belt 209 to displace synchronously under the drive of the support sleeve frame 208.
