Description

Technical Field

[0001] The utility model relates to the field of tire production equipment, in particular to a drum plate assembly and a tire carcass drum. Background Art

[0002] The carcass drum is the core component of the molding machine. After the rubber material is applied to the drum, it expands and forms a barreled preform. The molding machine then transfers the preform to the next station for molding. The process involves applying the rubber material, rolling it, radially expanding the drum, and then retracting it to remove the preform. The general flow is as follows: 1. During rubber application, a vacuum generator provides suction, and the molding machine provides power to rotate the drum, applying the material. 2. After application, the molding machine's pressure rollers apply pressure. 3. After rolling, the drum plate expands radially under the action of the lead screw and frustum, increasing the inner diameter of the preform barrel. 4. The molding machine's transfer ring holds the preform. The drum plate expands radially under the action of the lead screw and frustum, reducing the inner diameter of the preform barrel. 5. The transfer ring transfers the preform to the next station.

[0003] However, in the prior art, the bonding surface between the drum shell and the rubber compound is a flat structure, and a set of drum plates is used to bond rubber compounds of varying widths. Since only one set of drum plates is used for bonding rubber compounds of varying widths, it is impossible to adjust the rubber compound to the different widths. Furthermore, the thickness of the rubber compound varies at different locations during bonding, resulting in an uneven surface on the drum after bonding, and poor rolling performance.

[0004] Therefore, there is a problem in the prior art that the carcass bulge plate has poor performance. Utility Model Content

[0025] In order to solve the problem of poor performance of carcass drum plates in the prior art, the present application provides a drum plate assembly and a carcass drum.

[0026] Furthermore, the carcass drum in the present application has the drum plate assembly described below.

[0027] like Figure 1 As shown, the drum plate assembly in the present application includes a drum plate body 10 and an adjustment structure 20. The drum plate body 10 has a mounting opening 11 and a drum plate mounting structure 12 extending along the length direction of the drum plate body 10. There are two mounting openings 11, and the two mounting openings 11 are respectively arranged at both ends of the length direction of the drum plate mounting structure 12 and extend in a direction away from each other; at least one adjustment structure 20 is respectively arranged in each mounting opening 11, and at least a part of the adjustment structure 20 can move along the mounting opening 11.

[0028] When using the drum plate assembly of the present application, since the drum plate body 10 is provided with an adjustment structure 20, the adjustment structure 20 can be used to solve the problem of unevenness of the barrel surface after the rubber is applied due to the different thicknesses of different rubber materials, resulting in poor rolling effect. At the same time, since at least a portion of the adjustment structure 20 can move along the mounting opening 11, that is, at least a portion of the adjustment structure 20 can move along the length of the drum plate body 10, the distance between the adjustment structure 20 and the end of the drum plate body 10 can be changed by adjusting the position of the adjustment structure 20 in the length direction of the drum plate body 10, thereby adapting to rubber materials of different widths, thereby solving the problem in the prior art that the drum plate cannot be adjusted to the different widths of various rubber materials. Therefore, the drum plate assembly of the present application effectively solves the problem of poor performance of the carcass drum plate in the prior art.

[0029] Furthermore, it should be noted that, in the present application, when the position of the adjustment structure 20 along the length of the drum plate body 10 is adjusted, at least a portion of the adjustment structure 20 can move along the mounting opening 11 and will not separate from the mounting opening 11. Furthermore, with respect to the distance between the adjustment structure 20 and the end of the drum plate body 10 mentioned above, the adjustment structure 20 and the corresponding end of the drum plate body 10 are both located at the same end of the drum piece mounting structure 12.

[0030] On tire production lines, this adjustable drum plate assembly design significantly improves flexibility and efficiency. For example, when producing tires of different models or specifications, the entire drum plate assembly need not be replaced; simply adjusting the position of the adjustment structure 20 can adapt to various rubber compound sizes, significantly reducing production changeover time. Furthermore, this design effectively improves the consistency of rubber compound lamination, reducing defects in finished tires caused by uneven lamination, such as eccentricity and localized hardening, thereby enhancing the overall performance and service life of the tire.

[0031] In a specific embodiment of the present application, the adjustment structure 20 includes: a first adjustment block 21; a second adjustment block 22, the second adjustment block 22 is arranged on a side of the first adjustment block 21 away from the drum plate mounting structure 12, and in the thickness direction of the drum plate body 10, there is a height difference between the top surface of the first adjustment block 21 and at least a portion of the top surface of the second adjustment block 22.

[0035] Of course, in the present application, there can be multiple second adjustment blocks 22 and they can be divided into groups of two. The top surface shapes of the second adjustment blocks 22 in the same group are the same, and the top surface shapes of the second adjustment blocks 22 in different groups are different.

[0036] Optionally, the ends of the first adjustment block 21 and the second adjustment block 22 that are adjacent to each other are each provided with a cooperating snap-fitting structure. The provision of the snap-fitting structure can ensure a better fit between the ends of the first adjustment block 21 and the second adjustment block 22 that are adjacent to each other, thereby ensuring the stability of the connection between the first adjustment block 21 and the second adjustment block 22. Furthermore, in the present application, the cooperating snap-fitting structures can be snap-fitting grooves and snap-fitting protrusions, or cooperating snap-fitting surfaces.

[0037] Optionally, there are multiple first adjustment blocks 21, and any one of the multiple first adjustment blocks 21 can be selectively set on the mounting opening 11. In the length direction of the drum plate body 10, the distance between the two ends of at least one of the multiple first adjustment blocks 21 is different from the distance between the two ends of the other first adjustment blocks 21.

[0038] Optionally, there are multiple second adjustment blocks 22, and any one of the multiple second adjustment blocks 22 can be selectively set on the first adjustment block 21, and the shape and / or height of the top surface of at least one of the multiple second adjustment blocks 22 is different from the shape and / or height of the top surface of other second adjustment blocks 22.
