When the tire is vulcanized, the internal pressure of the bladder will exert a large force on the lower ring and the center ring seat. If the lower ring and the center ring seat have no hard limit, the position of the lower ring and the center ring seat will drop after being subjected to the force, which will cause the lower ring to drive the bladder down, which will pull the bladder to rupture and affect the vulcanization of the tire.

[0003] In view of the above problems, the present invention designs and manufactures a vulcanizing machine center mechanism locking mechanism and a vulcanizing machine to overcome the above defects. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a vulcanizer central mechanism locking mechanism and a vulcanizer, which can realize the hard limit of the lower ring and the ring seat during the tire vulcanization process without affecting the lower ring driving the bladder to descend, thereby ensuring the smooth vulcanization of the tire.

A lifting ring seat 3 is provided in the bladder 2, and a lower ring 4 is provided on the ring seat 3 to clamp the lower clamping edge of the bladder.

[0032] The inner wall of the capsule 2 of the present invention is provided with a boss 13, the inner diameter of the boss 13 is smaller than the outer diameter of the ring seat 3, and a first staggered tooth ring 15 is supported on the boss 13. The inner ring of the first staggered tooth ring 15 is provided with a plurality of first staggered teeth 10, and the outer ring of the first staggered tooth ring 15 is rotatably matched with the inner wall of the capsule 2.

[0033] A plurality of second staggered teeth 14 are provided on the outer wall below the ring seat 3. When the second staggered teeth 14 are aligned above the first staggered teeth 10, the ring seat 3 can be placed on the first staggered teeth 10.

[0034] It also includes a driving device 11, which can drive the first staggered tooth ring 15 to rotate.

[0035] Specifically, before the vulcanization of the tire begins, the driving device 11 drives the first staggered tooth ring 15 to rotate in advance, and the first staggered tooth 10 is aligned below the second staggered tooth 14. At this time, the ring seat 3 can be placed on the first staggered tooth ring 15. When the tire is vulcanized, the force applied to the lower ring 4 and the ring seat 3 by the internal pressure of the bladder can be borne by the first staggered tooth ring 15, preventing the ring seat 3 and the lower ring 4 from falling, thereby ensuring the smooth vulcanization of the tire; when the vulcanization is completed, the driving device 11 drives the first staggered tooth ring 15 to rotate, and the first staggered tooth 10 is staggered with the second staggered tooth 14. The ring seat 3 and the lower ring 4 can move downward, driving the bladder into the bladder tube 2, thereby ensuring the smooth removal of the tire.

[0036] In the present invention, at least one group of first staggered teeth 10 is provided, and the circumference of the multiple groups of first staggered teeth 10 is evenly distributed on the inner ring of the first staggered tooth ring 15. At least one group of second staggered teeth 14 is provided, and the circumference of the multiple groups of second staggered teeth 14 is evenly distributed on the outer wall below the ring seat 3 and corresponds to the multiple groups of first staggered teeth 10, thereby ensuring the stability of the first staggered tooth ring 15 in bearing the force.

[0038] The driving device 11 is preferably set as an oil cylinder or an air cylinder, of course, a motor can also be selected, which can also drive the first staggered tooth ring 15 to rotate through the transmission structure; specifically, when the driving device 11 selects an oil cylinder or an air cylinder, a support 12 is fixedly connected to the outside of the capsule 2, one end of the driving device 11 is hinged to the support 12, and the other end of the driving device 11 is hinged to a connecting rod 16, which passes through the avoidance groove and is connected to the first staggered tooth ring 15.

[0039] There is at least one driving device 11 , and multiple driving devices 11 are evenly distributed around the circumference of the outer side of the capsule 2 , and the connecting rod 16 is preferably arranged between two adjacent groups of first staggered teeth 10 .

[0040] The boss 13 of the utility model is close to the lower end of the capsule 2, and a connecting seat 7 is connected to the bottom of the ring seat 3. A plurality of second staggered teeth 14 are arranged on the outer wall of the connecting seat 7. The outer diameter of the connecting seat 7 is smaller than the inner diameter of the first staggered tooth ring 15 to avoid interference between the connecting seat 7 and the first staggered tooth ring 15 when the first staggered tooth 10 and the second staggered tooth 14 are staggered.

[0041] The bottom of the frame 1 of the present invention is provided with a first support frame 5, on which a capsule lifting drive device 6 is provided, which can drive the capsule 2 to rise and fall.

[0042] In addition, a vulcanizing machine is provided, which includes the above-mentioned vulcanizing machine central mechanism locking mechanism.

[0043] The specific locking and opening process of this utility model:

[0044] like Figure 3 As shown, before the tire vulcanization begins, the driving device 11 drives the first staggered tooth ring 15 to rotate in advance, and the first staggered tooth 10 is aligned below the second staggered tooth 14. At this time, the ring seat 3 can be placed on the first staggered tooth ring 15. When the tire is vulcanized, the force applied to the lower ring 4 and the ring seat 3 by the internal pressure of the bladder can be borne by the first staggered tooth ring 15, preventing the ring seat 3 and the lower ring 4 from falling, thereby ensuring smooth vulcanization of the tire;

[0045] like Figure 4 As shown, when vulcanization is completed, the driving device 11 drives the first staggered tooth ring 15 to rotate, the first staggered teeth 10 and the second staggered teeth 14 are staggered, and the ring seat 3 and the lower ring 4 can move downward, driving the capsule into the capsule tube 2 to ensure smooth tire removal.
