[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0021] Example:

[0022] like Figs. 1-4 As shown, this utility model provides an automatic traction device for cooling tire inner liner. Multiple cooling drums 1 are installed on a cooling rack in a staggered arrangement. Each cooling drum 1 has a large-diameter first sprocket 2 fixed to both sides by bolts, keyways, or welding. Multiple first sprockets 2 on the same side are sequentially connected by a chain 3 wound in an S-shape. The first sprockets 2 mesh with the chain 3. Multiple sprocket groups are installed on the cooling rack, and one or more of these sprocket groups are connected to a motor drive. Alternatively, multiple motors can be used to synchronously drive the first sprockets 2 to rotate, ensuring that the sprockets drive the chain 3 to operate normally. The sprocket assembly includes two second sprockets 4, which are coaxially and fixedly connected by a connecting rod. This allows the motor to drive one of the second sprockets 4 to rotate, simultaneously driving the other second sprocket 4 to rotate. The chain 3 forms a link by passing through the corresponding second sprocket 4. In this embodiment, there are three sprocket assemblies, which are respectively installed at the triangular part of the cooling rack, so that they together with the first sprockets 2 on the multiple cooling drums 1 form a complete link. A traction roller 5 is installed between the two chains 3 by a fixing component. The traction roller 5 is used to drive the inner lining layer to be wound sequentially around the multiple cooling drums 1.

[0023] Furthermore, the distance between the two second sprockets 4 is equal to the distance between the two first sprockets 2 on the same cooling drum 1, thereby ensuring that the distance between the two chains 3 remains consistent, further ensuring that the traction roller 5 can be smoothly installed between the two chains 3, and ensuring the smooth operation of the inner lining traction work.

[0024] Furthermore, the traction roller 5 includes a roller body 51 and a shaft end 52. The shaft end 52 is fixedly installed on both sides of the roller body 51. The length of the roller body 51 is less than the distance between the two first sprockets 2 on the same cooling drum 1, ensuring that the roller body 51 can smoothly pass through the outer surface of the cooling drum 1 without jamming.

[0025] Furthermore, the height of the top of the first sprocket 2 from the surface of the cooling drum 1 is greater than the diameter of the roller body 51, ensuring that the traction roller 5 can pass through all the cooling drums 1 normally.

[0026] Further, the fixing component comprises a threaded hole one 6 and a bolt one, the threaded hole one 6 is coaxially arranged in the shaft end 52, the shaft end 52 penetrates through the corresponding connecting hole 7 of the chain 3, and the threaded hole one 6 is threadedly connected with the bolt one.

[0027] The connecting buckle of one of the corresponding chain links 3 in the two links is removed, the shaft end 52 of the traction roller 5 is outwardly inserted into the corresponding connecting hole 7, the shaft end 52 penetrates through the connecting hole 7, and the threaded hole one 6 is threadedly connected with the bolt one, so that the traction roller 5 is installed between the two chains 3, the installation mode is simple and easy to operate, and the practicability is high.

[0028] Further, the shaft end 52 is fixedly installed with a limiting ring 8 on the side away from the threaded hole one 6. The limiting ring 8 is arranged to limit the axial displacement of the traction roller 5 without affecting the normal traction of the traction roller 5, so that the traction roller 5 cannot move too far in the axial direction and cannot smoothly pass through the surface of the cooling drum 1.

[0029] Further, when the number of the cooling drums 1 is relatively large, the second sprocket 4 can also be installed on the two sides of the cooling drum 1, and the installation position is the same as that of the first sprocket 2, so that the first sprocket 2 and the second sprocket 4 jointly form a complete link, one or more of the first sprocket 2 or the second sprocket 4 is driven to rotate synchronously by using a motor, so that the traction roller 5 is driven to pass along a specified route, and the inner liner is pulled to the corresponding cooling drum 1.

[0030] The working principle of the embodiment is as follows:

[0031] When the material head or tail of the inner liner reaches the front of the cooling drum 1 during production, the material head or tail is overlapped and fixed on the roller body 51 of the traction roller 5, because the inner liner has certain viscosity during production, so that the inner liner is fixed reliably after being wound on the roller body 51 under the action of viscosity, then the motor is started, the motor drives the two chains 3 to start running, and then synchronously drives the cooling drum 1 and the traction roller 5 to run, so that the inner liner is conveyed along the chain 3 under the driving of the traction roller 5 and is wound on the cooling drum 1, thereby realizing automatic pulling of the inner liner, and the structure is simple and the practicability is high.

[0032] In the description of the utility model, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inner", "outer", "back", "middle" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, therefore it cannot be understood as a limitation on the utility model.

[0033] The above is only a specific embodiment of the present application, and cannot limit the scope of the present application. Therefore, the replacement of equivalent components or equivalent changes and modifications made within the scope of the present application should still fall within the scope of the present application.
