Description

Technical Field

[0001] The utility model belongs to the technical field of tire vulcanizers, and in particular relates to a central mechanism device of a vulcanizer for tire processing. Background Art

[0002] Tire vulcanizer is used for vulcanizing pneumatic tires such as automobile tires, aircraft tires, engineering tires and tractor tires. There are three types of vulcanizers: electric heating, steam heating and thermal oil heating. The heat source for tire vulcanization mainly comes from the inside, usually hot water or steam, so the internal temperature is relatively high. The mechanism that controls the tire to flip and move in the vulcanizer is called the central mechanism of the tire vulcanizer.

[0003] However, when the central mechanism of the existing tire vulcanizer drives the green tire into the vulcanizing mechanism for vulcanization, the green tire undergoes changes in shape and volume. During this process, due to the lack of monitoring means for the vulcanization temperature of the green tire at different heights in the vulcanizing mechanism, it is easy to produce uneven vulcanization reaction or large temperature deviations at different heights when the temperature changes, thereby affecting the quality of the tire after vulcanization.

[0004] Reference to the Chinese authorized patent with authorization announcement number: CN220198619U: A tire vulcanizer central mechanism. This utility model can monitor the temperature of different internal heights during tire vulcanization, so as to better observe and control the temperature during vulcanization, thereby reducing the deviation of the vulcanization reaction due to uneven temperature.

[0005] However, during use, it can only monitor the temperature at different heights in the tire, but cannot monitor the temperature at different positions in the tire. The monitoring range is limited, thus affecting the monitoring accuracy. Utility Model Content

[0009] In a further embodiment, a fixing column is fixed inside the limiting sleeve, two sliding blocks are movably connected to the outside of the fixing column, and a supporting spring for supporting the sliding blocks is sleeved on the outside of the fixing column.

[0010] In a further embodiment, limit pins are fixed on opposite back surfaces of the two sliding blocks, moving grooves for the limit pins to move are formed on both sides of the limit sleeve, and a connecting rod is provided above the sliding block.

[0011] In a further embodiment, a guide block is provided above the connecting rod, and both ends of the connecting rod are rotatably connected to connecting seats fixedly connected to the sliding block and the guide block.

[0012] In a further embodiment, a movable hole is provided at the top of the limiting sleeve, and a lifting pin fixedly connected to the guide block is movably connected in the movable hole at the top of the limiting sleeve.

[0013] Technical effects and advantages of the utility model:

[0014] The central mechanism device of the tire processing vulcanizer blows air into the central rod through the air inlet pipe, pushing the piston and the support column to move in the central rod and the top pipe, cooperating with the rotating block to make the connecting block move along the arc groove of the outer wall of the top pipe, thereby driving the connecting ring and the temperature sensor to rotate and move up and down on the outer wall of the top pipe, monitoring the temperature at different heights and positions inside the tire, thereby ensuring the accuracy of temperature monitoring;
