Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tire manufacturing, in particular to a tread rolling machine for tire manufacturing. Background Art
[0002] With the development of the times, tire retreading has complied with its environmental protection theme, which has led to the vigorous development of tire retreading. During tire retreading, the new tread is attached to the surface of the old tire, and then the tire is retreaded through vulcanization reaction. This method is called hot retreading. In cold retreading, the polished and repaired tire is placed on a fixed frame, and its inner ring is propped open by a machine. Then the rubber needs to be softened, and then the glue spraying equipment is placed close to the tire, and the newly extruded rubber is applied layer by layer on its surface, and then it is pressed and compacted by a roller. The tire is then pressed on the roller. When loading, the inside of the tire is first limited by a limiting device, and then the tire is inserted into the rolling machine, and the tire is rotated to complete the rolling of the tire. However, after completing the rolling of one tire, the tire needs to be removed from the limiting device, and then another new tire is limited by the limiting device and then inserted into the rolling machine. During this process, the machine needs to be stopped to limit the tire, which makes the rolling process not continuous, wastes a lot of time, and thus reduces its rolling efficiency. For this reason, we propose a tread rolling machine for tire manufacturing. Utility Model Content

[0027] See also Figures 1 to 6A second electric push rod 15 is fixed to the top of the rolling base 2, and a connecting bracket 16 is fixed to the bottom of the second electric push rod 15. Driven by the second electric push rod 15, the connecting bracket 16 can move in the vertical direction. The second electric push rod 15 is a prior art and is not described here. Fixed rods 17 are fixed at both ends of the connecting bracket 16, and a straight-face pressure roller 10 is movably sleeved in the middle of the fixed rod 17.

After the curved surface of the curved pressure roller 18 contacts the curved surface of the outer side of the tire 5, the curved pressure roller 18 can be extended and retracted relative to the straight pressure roller 10 under its lifting action, and then gradually rolls the curved surface of the outer side of the tire 5. After the straight pressure roller 10 contacts the tire 5, it rolls the middle of the outer side of the tire 5. After the tire 5 is rolled, the tire 5 can be pulled out of the middle of the rolling base frame 2 under the drive of the movable plate 7. At this time, under the drive of the output shaft of the first motor 8, the replacement plate 6 can be flipped 180 degrees to complete the replacement of the tire 5.
