[0002] The traditional post-pressing rollers of the carcass are divided into two pairs, a total of four hard rubber pressing rollers. The hard rubber pressing rollers are relatively wide in size and have a large contact area. However, the width of the bead part is relatively narrow, and the thickness is inconsistent at the junction of the parts, thus locally raising the rolling contact surface between the pressing roller and the part, resulting in difficult air exhaust at the junction of the parts. Similarly, after the carcass is laminated, the thickness at the edge of the bead position of the tire bead is relatively large, and the traditional rubber roller cannot well press and compact the gap at the junction, making it difficult to discharge the air bubbles at the bead position of the tire embryo. To solve the above problems, a new technical solution is provided. Content of the Utility Model

Detailed Embodiment

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0017] Such as Figures 1-3As shown in the figure, a multi-piece special-shaped pressing roller with different material combinations for exhausting air from a tire composite includes a fixed arm 1. A chute 2 is provided in the middle of the fixed arm 1. A bidirectional screw 3 and a slider 4 are arranged on the chute 2. The bidirectional screw 3 is connected to the middle inside the chute 2 through an interference fit of a bearing. The slider 4 is symmetrically nested in the upper and lower parts inside the chute 2, and the slider 4 is threadedly connected to the bidirectional screw 3. Sleeves 5 are symmetrically sleeved on the upper and lower sides outside the fixed arm 1. The sleeves 5 are fixedly connected to the sliders 4 by screws. An extension block 6 and a locking plate 7 are arranged on the sleeves 5. The extension block 6 is integrally formed and connected to the front end of the sleeve 5. The locking plate 7 is fixedly installed on the left end of the sleeve 5 by screws. A convex groove 8 is provided inside the extension block 6. A convex block 9 is nested inside the convex groove 8. A docking block 10 is integrally formed and connected to the front end of the convex block 9. A screw hole 11 is provided in the middle of the convex block 9. An adjusting screw 12 is connected to the front end of the locking plate 7 through an interference fit of a bearing. The inner end of the adjusting screw 12 is threadedly connected to the screw hole 11. A docking shaft 13 is integrally formed and connected to the front end of the docking block 10. A multi-piece serrated pressing roller 14 is connected to the docking shaft 13 through an interference fit of a bearing. The upper multi-piece serrated pressing roller 14 is made of metal, and the lower multi-piece serrated pressing roller 14 is made of rubber.

[0018] Specific usage method: According to the specification model of the carcass cylinder, turn the bidirectional screw 3 to drive the slider 4 to slide relatively. The relative sliding of the slider 4 drives the sleeve 5 to slide relatively along the fixed arm 1. The relative sliding of the sleeve 5 adjusts the distance between the upper and lower multi-piece serrated pressing rollers 14. Then, move the upper and lower multi-piece serrated pressing rollers 14 on the fixed arm 1 to the outside of the carcass cylinder for composite compaction operation. When the upper multi-piece serrated pressing roller 14 or the lower multi-piece serrated pressing roller 14 is worn out, turn the upper adjusting screw 12 or the lower adjusting screw 12 to drive the corresponding convex block 9 to slide outwards along the convex groove 8. The outward sliding of the convex groove 8 drives the corresponding multi-piece serrated pressing roller 14 to slide forward, so that the upper and lower multi-piece serrated pressing rollers 14 can be in contact with the outside of the carcass cylinder at the same time.
