Therefore, the operation is more convenient.

When a tire is placed on the annular plate 5, the small air cylinder 405 is started, the telescopic rod of the small air cylinder 405 extends to drive the left-side molding-back block 404 to rotate positively, the left-side molding-back block 404 rotates positively to drive the left-side rotating shaft 401 to rotate positively, the left-side rotating shaft 401 rotates positively to drive the left-side chain wheel 402 to rotate positively, the left-side chain wheel 402 rotates positively to drive the other two chain wheels 402 to rotate positively through the chain 403, the other two chain wheels 402 rotate positively to drive the corresponding molding-back block 404 to rotate positively, the molding-back block 404 rotates positively to drive part of parts of the inner top assembly 7 to rotate positively, when the molding-back block 404 rotates in parallel with the end of the support frame 3, the small air cylinder 405 is closed, the outer end of the molding-back block 404 also rotates positively to the tire, part of the inner top assembly 7 also rotates positively to the. In a similar way, when the tire top cover was in tire outside circumference, and when interior top subassembly 7 reseed and the tire was inside to break away from, the telescopic link that starts small cylinder 405 shortened and drives the left side and return the type piece 404 reversal and reset, just also made two other types piece 404 reversals and resets, simultaneously, returns type piece 404 and still drives the partial part reversal of interior top subassembly 7 and resets, closes small cylinder 405.

When the telescopic rod of the small air cylinder 405 is extended, the reverse rotation block 404 drives the sliding block 709 to rotate forward, the sliding block 709 drives the contact block 711 to rotate forward, meanwhile, the reverse rotation block 404 also drives the sleeve 712 to rotate forward, and further, when the reverse rotation block 404 is in a parallel state with the guide rail 706, the small air cylinder 405 is closed, the reverse rotation block 404 stops rotating forward, the sleeve 712 rotates forward into the tire, the servo motor 601 is started to rotate forward, the servo motor 601 rotates forward to drive the first gear 701 to rotate forward, the first gear 701 rotates forward to drive the second gear 704 to rotate backward, the second gear 704 rotates backward to drive the hollow tube 703 to rotate backward, the hollow tube 703 rotates backward to drive the spiral fluted disc 705 to rotate backward, the spiral fluted disc 705 rotates backward to drive the first contact rod 708 to move outward, the first contact rod 708 moves outward to drive the push rod 707 to move outward, when the push rod 707 moves outward to contact the contact block 711 moves outward to drive the sliding block 709 to move outward, the first spring 710 is compressed, the sliding block 709 moves outwards to drive the connecting rod 714 to move outwards, the connecting rod 714 moves outwards to drive the sliding rod 713 to move outwards, the sliding rod 713 moves outwards to drive the sleeve 712 to swing outwards, the sleeve 712 swings outwards to enable the bottom end to be in contact with the inside of the tire, and further when the sleeve 712 swings outwards to be in a vertical state, the sliding block 709 drives the sliding rod 713 to move upwards through the connecting rod 714, the second spring 715 is stretched, the sliding rod 713 moves upwards to be in contact with the inside of the tire to jack up the tire, so that the periphery of the tire is reduced, the servo motor 601 is turned off, the spiral groove disc 705 stops driving the first contact rod 708 to move outwards, the sliding rod 713 stops moving upwards, the operator can sleeve the tire top in the circumferential direction, after the tire top is sleeved, the servo motor 601 is started to rotate reversely, the spiral groove disc rotates forwards, the spiral groove disc 705 drives the first contact rod 708 to move inwards to reset, the first, due to the action of the first spring 710, the sliding block 709 moves inwards to drive the sliding rod 713 to move downwards for resetting through the connecting rod 714, the sliding rod 713 resets and is separated from the inside of the tire, the tire resets and is tightly contacted with the top of the tire, the connecting rod 714 drives the sleeve 712 to swing inwards for resetting through the sliding rod 713, the telescopic rod of the small cylinder 405 is started again to shorten, the return block 404 is driven to rotate reversely for resetting, and the return block 404 resets and drives the sleeve 712 to rotate reversely for resetting. Thus, the tire can be sleeved on the tire.

Example 2

On the basis of embodiment 1, as shown in fig. 5 and 6, the device further comprises a special-shaped fixture block 8 and a third spring 9, the special-shaped fixture block 8 is symmetrically placed on the inner side of the bottom of the clip block 404 in a sliding manner, the special-shaped fixture block 8 is in contact fit with the contact block 711, the special-shaped fixture block 8 is further in fit with the push rod 707, and the third spring 9 is connected between the outer side of the top end of the special-shaped fixture block 8 and the inner portion of the clip block 404.

When the molding back block 404 rotates forward, the special-shaped fixture block 8 limits the sliding block 709, and further when the push rod 707 moves outward, the push rod 707 contacts the special-shaped fixture block 8, the push rod 707 drives the special-shaped fixture block 8 to move outward, the third spring 9 is stretched, when the special-shaped fixture block 8 moves outward and is separated from the sliding block 709, the push rod 707 continues to move outward to drive the sliding block 709 to move outward. When the push rod 707 moves inwards to reset, the push rod 707 is separated from the sliding block 709, the sliding block 709 moves inwards to reset, meanwhile, the push rod 707 is separated from the special-shaped fixture block 8, and under the action of the third spring 9, the special-shaped fixture block 8 moves inwards to contact with the sliding block 709 to limit the special-shaped fixture block. Thus, when the swage block 404 rotates, the slider 709 can be prevented from moving due to the rotating force.

As shown in fig. 3, a second contact rod 10 is further included, and the second contact rod 10 is fixed to the outer end of the clip block 404.

When the shape-returning block 404 rotates forwards, the shape-returning block 404 further drives the second contact rod 10 to rotate forwards, the second contact rod 10 rotates forwards to contact with the inside of the tire, the three second contact rods 10 contact with the inside of the tire to be located at the middle position, and then when the sleeve 712 swings outwards to be in a vertical state, the sleeve 712 is separated from the second contact rod 10. When the sleeve 712 is swung inward to return, the sleeve 712 again contacts the second contact lever 10. Thus, the tire position can be shifted to the center.
