Description

Technical Field

[0001] The utility model relates to the technical field of tire processing, in particular to a rubber pressing device for tire retreading. Background Art

[0002] With the progress of society, cars can be seen everywhere and become a common means of transportation for people. As more and more cars appear, there are more and more waste tires. When people refurbish these tires.

[0003] However, the existing tire molding has poor tread adhesion, which is prone to cracking after long-term use, resulting in uneven wear of the tire. Therefore, in order to improve the glue pressing effect after tire retreading, some technologies have proposed relevant technical structures to assist the glue pressing of tire retreading. For example, there is a utility model patent with a publication number of CN207630574U, which proposes a retread tire molding machine. The die-cutting roller can extrude and mold the tire fixed on the fixing device, thereby ensuring that the colloid on the tire tread can be bonded to the tread.

[0004] From the above disclosed technical contents, theoretically speaking, the implementation of the relevant technical structure is conducive to the shaping of the rubber after tire retreading. However, according to the description in the above disclosed technical contents, the tire needs to be placed on the tire fixing device during the process of rubber shaping. In actual use, due to the different tire sizes, the diameter values ​​of the inner wall of the tire are also different. When the diameter value inside the tire is smaller than the diameter value of the tire fixing device, the tire cannot be placed on the tire fixing device. At the same time, when the diameter value inside the tire is larger than the diameter value of the tire fixing device, the tire will fall off the tire fixing device during the rubber shaping process, thereby causing inconvenience to the rubber shaping process of tire retreading.

Due to the threaded connection between the No. 1 ball screw 102 and the No. 1 ball nut 101, and the outer walls of the No. 1 ball screw 102 on the left and right sides are provided with threads in opposite directions, the rotating shaft 16 drives the No. 1 ball screw 102 on the left and right sides to move toward the tire at the same time when it rotates. When the No. 1 ball screw 102 moves, the inner side of the clamping plate 8 is connected to the outer wall of the tire through the connection of the vertical rod 9 and clamped. Then, turn on the power of the No. 3 electric push rod 21 and the No. 2 electric push rod 20. After the No. 2 electric push rod 20 is turned on, the tire is raised to the position of the fixed ring 1, and the opening of the No. 3 electric push rod 21 moves the tire to the outside of the fixed ring 1. Turn on the power of the No. 1 electric push rod 3. After the No. 1 electric push rod 3 is turned on, it drives the support plate 6 to move toward the inner wall of the tire until the anti-slip pad 7 contacts the inner wall of the support plate 6, so that the tire can be fixed by the fixed ring 1. Finally, turn on the power of the No. 1 rotating motor 13 and the driving motor 22. After the driving motor 22 is turned on, the height of the tire is adjusted, and the turning on of the No. 1 rotating motor 13 drives the rotation of the tire. Then move the die-cutting equipment 2 to contact the tire to achieve the gluing of the tire.
