Description

Technical Field

[0001] The utility model relates to the technical field of tire preparation, in particular to a pressing mechanism for an inner liner joint. Background Art

[0002] During the tire manufacturing process, the inner liner needs to be aligned with the standard beacon and attached to the forming drum, the head and tail of the inner liner need to be attached together, and then the inner liner joint is pressed with a pressing roller to ensure that it is tightly connected and the inner liner joint will not crack during the subsequent inflation and shaping process.

[0003] However, the existing laminating roller is a cylindrical structure with a flat sidewall. When the existing laminating roller is used to press the inner liner joint, the flat sidewall of the laminating roller cannot adapt well to the shape of the inner liner curved surface, resulting in uneven pressure during the laminating process. This uneven laminating effect makes the inner liner joint prone to cracking when the forming drum is inflated and shaped, resulting in unqualified products and seriously affecting the quality and safety of the tire. This not only wastes production resources and reduces production efficiency, but also has a serious impact on the company's economic benefits. Utility Model Content

[0004] In order to solve the deficiencies in the prior art, the utility model provides a pressing mechanism for an inner lining joint.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is: a laminating mechanism for an inner lining joint, comprising a support seat, support arms are symmetrically arranged on the left and right sides of the support seat, a laminating roller is rotatably arranged at the end of the support arm, the side wall of the laminating roller is arc-shaped, and a plurality of laminating roller protrusions are evenly arranged on the side wall of the laminating roller.

[0006] Furthermore, the raised top of the lamination roller is a smooth curved surface.

[0007] Furthermore, the height of the protrusion of the lamination roller is 3 to 6 mm.

[0008] Furthermore, the distance between adjacent protrusions of the lamination roller is 1 to 4 mm.

[0009] Furthermore, a rotating shaft is provided through the laminating roller, the rotating shaft is provided on the supporting arm, and bearings are provided on the outer sides of both ends of the rotating shaft.

[0010] Furthermore, the bearing is a 6902 model bearing.

[0011] Furthermore, the support arms extend toward the middle of the support seat, and the angle formed by the support arms and the support seat is 10 to 60 degrees.

[0012] Furthermore, the arc angle of the arc-shaped side wall of the lamination roller is 5 to 9 degrees.

[0013] Furthermore, the pressing roller is made of alloy material.

[0014] The beneficial effects achieved by the utility model are:

[0015] 1. The side wall of the lamination roller in the utility model is of arc-shaped design. The lamination roller with the arc-shaped side wall structure can perfectly fit the inner liner joint on the molding drum. During the lamination process, the contact surface between the lamination roller and the inner liner joint is more fitted and more uniform, ensuring that the inner liner obtains uniform and enhanced pressure during the lamination process, thereby significantly improving the lamination effect, and effectively preventing the inner liner from cracking, reducing the generation rate of defective products, improving the production quality of tires, and improving production efficiency and economic benefits.

[0023] In order to better understand the purpose, structure and function of the utility model, the pressing mechanism of the inner lining joint of the utility model is further described in detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 4As shown, a pressing mechanism for a lining joint includes a support seat 1, which can be horizontally moved left and right and arranged on a forming machine. A support arm 2 is symmetrically arranged on one side of the support seat 1 opposite to the forming drum in the forming machine, and a pressing roller 3 is rotatably arranged on the other end of the support arm 2. The inside of the pressing roller 3 is a hollow structure, and a rotating shaft 5 is arranged inside the pressing roller 3. The upper and lower ends of the rotating shaft 5 are arranged in the support arm 2, and the outer sides of the two ends of the rotating shaft 5 are arranged. The bearing 4 is selected as a 6902 model bearing 4. Through the arrangement of the rotating shaft 5 and the bearing 4, the pressing roller 3 can rotate freely in the support arm 2. The left and right support arms 2 both extend to the middle position of the support seat 1, so that the distance between the left and right pressing rollers 3 is relatively close, ensuring the pressing effect of the lining joint, and the angle between the support arm 2 and the projection of the support arm 2 on the support seat 1 is 10 to 60 degrees.

[0025] The side wall of the lamination roller 3 is designed to be arc-shaped, and the arc formed by the arc of the side wall of the lamination roller 3 is 5 to 9 degrees. The lamination roller 3 with an arc-shaped side wall structure can perfectly fit the inner lining joint on the molding drum, ensuring that the inner lining joint is subjected to uniform force during the lamination process, thereby improving the lamination effect and reducing the rate of defective products.

[0026] A number of laminating roller protrusions 6 are evenly arranged on the side wall of the laminating roller 3. The height of the laminating roller protrusions 6 is 3 to 6 mm, and the distance between adjacent laminating roller protrusions 6 is 1 to 4 mm. The laminating roller protrusions 6 are generally regular quadrangular prism structures, and the top of the laminating roller protrusions 6 is a smooth arc surface to prevent the laminating roller 3 from crushing the lining layer when laminating the lining layer joint. The laminating roller protrusions 6 can increase the pressure of the laminating roller 3 on the lining layer joint, thereby further improving the laminating effect of the lining layer joint.

[0027] The lamination roller 3 and the lamination roller protrusion 6 are made of the same material, both of which are made of a relatively hard alloy material, so as to ensure the hardness and wear resistance of the lamination roller 3 and improve the service life of the lamination roller 3.

[0028] The working principle of the utility model is:

[0029] When the inner lining is aligned with the light mark according to the standard and fits on the forming drum, the forming drum starts to rotate, and the inner lining joint rotates to align with the pressing mechanism and then stops rotating. The pressing roller 3 in the pressing mechanism is aligned with one side of the inner lining joint, and the pressing mechanism approaches the inner lining joint under the action of the ejection cylinder. When the pressing roller 3 presses against the inner lining joint, the ejection cylinder stops moving, and the motor starts. The motor controls the screw rod and then controls the support seat 1 on the screw rod to move toward the other end of the inner lining joint. During the movement of the support seat 1, the pressing roller 3 in the support arm 2 rotates and presses the inner lining joint. After the pressing roller 3 moves to the other end of the inner lining joint, the pressing work of the inner lining joint is completed, the ejection cylinder retracts, and the pressing mechanism returns to the initial position driven by the motor to prepare for the next pressing work of the inner lining joint.
