[0025] In specific implementation, when producing the inner tube, it is necessary to send the inflated inner tube into the vulcanizer for vulcanization processing. When limiting the inner tube, the inner tube is placed in the limiting groove inside the movable plate 5. At this time, the limiting blocks 10 in the movable plate 5 are in a separated state, and the gaps between them are large. The inner tube can enter the limiting groove of the inner tube without pressing. Then the hydraulic cylinder 4 can be started to drive the movable plate 5 to move upward. When the movable plate 5 moves, it will drive the connecting rod 6 to move upward. When the connecting rod 6 contacts the heating plate 3, the connecting rod 6 will When the connecting rod 6 moves, it will push the connecting plate 7 to move downward. When the connecting plate 7 moves, it will squeeze the first spring 8 at the bottom. At the same time, the connecting plate 7 can drive multiple groups of protrusions 22 to move downward synchronously. When the protrusions 22 move, they will drive the two groups of connecting rods 9 to rotate and merge. The rotating connecting rods 9 can drive the two groups of limit blocks 10 to approach, so as to limit the tire. The limit rod 11 will limit the limit block 10 and push the inner tube to the position of the heating groove at the bottom of the heating plate 3. The annular heating groove at the bottom of the heating plate 3 can vulcanize the inner tube;

[0026] After the processing is completed, the hydraulic cylinder 4 can be started to drive the movable plate 5 to move downward. When the connecting rod 6 is out of contact with the heating plate 3, the first spring 8 will be reset to push the connecting plate 7 to move upward. At this time, the connecting rod 9 will be unfolded to push the two sets of limit blocks 10 to separate. In this way, the above operation can facilitate the limiting of the inner tube in the inner tube vulcanizer.

[0028] During specific implementation, when the inner tube is produced, the inflated inner tube needs to be sent to the vulcanizer for vulcanization processing. When the inner tube processed in the inner tube vulcanizer is taken out, the staff can step on the pedal 12. When the pedal 12 moves down, the second spring 13 at the bottom is squeezed. At the same time, the rack rod 14 at the bottom of the pedal 12 will mesh with the first gear 15, driving the first gear 15 to rotate. The first gear 15 can drive the first synchronous wheel 16 to rotate. The first synchronous wheel 16 can drive the second synchronous wheel 18 to rotate through the synchronous belt 17.
