Description
Technical Field
[0001] This utility model relates to the field of tire sidewall production technology, specifically to an automatic lateral rolling device for tire sidewall joints. Background Technology
[0002] Sidewall end-to-end splicing is a key process in tire manufacturing, mainly involving the joining of the two ends of the sidewall rubber compound. It significantly impacts the overall performance and quality of the tire. The sidewall is the rubber layer between the tire carcass and the tread, primarily serving to protect the tire carcass, cushion impacts, and dissipate heat. Sidewall end-to-end splicing refers to joining the two ends of the sidewall rubber compound together during tire manufacturing to form a continuous ring structure.
[0003] Regarding the above and existing related technologies: During tire production, the tire sidewalls need to be joined together to form a circular bead. To ensure a tight bond at the joint, a simple hand-held mechanical roller is currently used to roll along the joint. This manual rolling increases labor costs and hinders the development of automation, resulting in a lack of improved production efficiency. Therefore, an automatic lateral rolling device for tire sidewall joints is proposed to address these issues. Utility Model Content

[0034] Working principle: When the tire sidewall joint needs to be rolled, the base 2 and connecting seat 1 are fixed, and the longitudinal cylinder 7 and connecting head 11 are fixed together. Then, the longitudinal cylinder 7 on the cylinder seat 3 is activated, causing the longitudinal cylinder 7 to drive the fixed seat 12 to move. The fixed seat 12 drives the connecting chain 4 to move. At the same time, the fixed seat 12 also moves on the surface of the slider 6 via the guide rail 5. When the fixed seat 12 moves, it causes the guide roller to press against the tire sidewall. Then, the rodless cylinder 8 is activated, driving the roller seat 13 to move. The roller seat 13 drives the pressure roller 9 on the tire sidewall. The side surface rolls. When the angle of the rodless cylinder 8 needs to be adjusted, the adjusting bolt 14 is rotated. The adjusting bolt 14 rotates on the inner surface of the fixed seat 12 and the surface of the rodless cylinder 8. Part of the structure of the fixed seat 12 will be moved along with it, and the rodless cylinder 8 will be pushed by the adjusting bolt 14. The rodless cylinder 8 rotates on the surface of the fixed seat 12. When the rodless cylinder 8 rotates, it will also rotate on the surface of the scale 10. After the rodless cylinder 8 rotates to the appropriate angle on the scale 10, the adjusting bolt 14 is stopped. By setting the entire device, full automation can be achieved. Rolling completely replaces manual labor. The pressing angle can be adjusted according to different tire sidewall dimensions to meet different specifications. Lateral rolling uses a rodless cylinder 8 to ensure that the movement trajectory runs along the joint line. When installing the connecting seat 1, the reinforcing plate 151 and the connecting seat 1 are aligned, and then the filling pad 152 is placed on the reinforcing plate 151 and the connecting seat 1. When the filling pad 152 moves, the filling pad 152 will be placed on the surface of the locking block 154 through the slot 155. The filling pad 152 will also drive the connecting block 156 to move its position. After the two sets are installed on the surface of the reinforcing plate 151 and the connecting seat 1, the positioning pin 153 is rotated to the inner wall of the reinforcing plate 151 and the filling pad 152, and then the positioning strip 157 is rotated to the inner wall of the two connecting blocks 156 and the reinforcing plate 151. Then, the connecting seat 1 and the reinforcing plate 151 are fixed to other equipment using the fixing bolt. By setting the entire device, the strength of the connection between the connecting seat 1 and other equipment can be increased, and the gap between the fixing bolt and the reinforcing plate 151, the connecting seat 1 and other equipment can be reduced, thereby increasing the stability of the installation.
