Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wheel inner lining film production, in particular to a molding device for processing wheel inner lining film. Background Art
[0002] The tire inner liner, also called the sealant, is the layer of material beneath the tread base of radial and bias-belted tires, circumferentially clamping the tire carcass along the tread centerline. Besides cushioning impacts, it primarily holds the carcass in place. For radial tires, it's also the primary load-bearing component. Therefore, high-strength, high-modulus and small-angle arranged cords should be used as the reinforcement material, and at the same time covered with high-elongation, high-hardness rubber, which is equivalent to the inner tube of the tire. It has a good sealing effect to ensure the air pressure of the tire. The rubber sheet can be used as an inner liner, a thin rubber strip, a belt layer edge glue or used to prepare carcass cord or belt layer material during tire molding. When preparing the film, a variety of raw materials are usually mixed to form a rubber strip, which is then pressed into shape by the calendering roller of a calender. After the preparation of the film, there are often bubbles in the raw material of the film. When the film is calendered, due to the direct pressing of the calendering roller, the rubber strip will be deformed during the pressing process, and then in close contact with the calendering roller, resulting in the discharged bubbles being easily pressed into the rubber strip again, thereby affecting the molding quality of the rubber strip and causing product quality defects. For this reason, we propose a molding equipment for processing wheel inner liner film. Utility Model Content

[0021] See also Figures 1 to 4 A forming device for processing wheel inner lining rubber sheet includes a main frame 1.

Both ends of the auxiliary roller 3 are provided with movable extension plates 4. When calendering, the extension plates 4 move toward the two ends of the auxiliary roller 3 under the action of the extrusion force, thereby driving the rubber strip to extend and flatten, so that the bubbles in the rubber strip can be discharged more smoothly. The extension plates 4 can move toward both ends to flatten the rubber strip and exhaust the air, and the rubber strip can be flattened and exhausted between the calendering rollers. 2 and one end of the auxiliary roller 3 are fixedly connected to the first conical direction-changing gear 10 that drives them to rotate together.

The driving rod 7 is fixed to the second conical direction-changing gear 12 in the middle, and the driving rod 7 is movably connected to the second conical direction-changing gears 12 at both ends. The driving rod 7 and the second conical direction-changing gears 12 at both ends can move relative to each other, and the driving rod 7 can drive the second conical direction-changing gears 12 at both ends, thereby enabling the second conical direction-changing gears 12 at both ends to rotate.
[0023] See also Figures 1 to 2 The middle calendering roller 2 is movably connected with a positioning plate 9, so that the calendering roller 2 can rotate at a fixed position on the positioning plate 9. The positioning plate 9 is fixed to the main frame 1, and the positioning plate 9 is movably connected with the adjusting rod 8, so that the adjusting rod 8 can rotate at a relatively fixed position on the positioning plate 9.
[0024] See also Figures 1 to 2 , opposite threads are provided at both ends of the adjusting rod 8, and adjusting plates 11 are threadedly mounted on both ends of the adjusting rod 8. Under the rotation of the adjusting rod 8, the two adjusting plates 11 can rotate relative to each other, and the two adjusting plates 11 are movably connected to the calendering roller 2 and the auxiliary roller 3 at both ends, so that they can rotate in a fixed position on the adjusting plate 11.
[0025] See also Figures 1 to 2 The adjusting plate 11 is movably connected to the second conical direction-changing gears 12 at both ends, so that the adjusting plate 11 can drive the second conical direction-changing gear 12 to move and adjust together with the first conical direction-changing gear 10, and a first motor 5 and a second motor 6 are fixed to the outside of the main frame 1. The output shafts of the first motor 5 and the second motor 6 are fixed to the driving rod 7 and the adjusting rod 8, respectively. Under the respective drive of the output shafts of the first motor 5 and the second motor 6, the first motor 5 and the driving rod 7 can rotate respectively.

[0026] See also Figures 1 to 5 The auxiliary roller 3 is connected to a first bracket 14 through an axle pin, so that the auxiliary roller 3 and the first bracket 14 can rotate relative to each other.

[0028] In summary, when the wheel inner lining film processing forming equipment is used, the film raw material first passes between the calendering roller 2 and the auxiliary roller 3, and then passes through the calendering roller 2 for calendering forming. Driven by the output shaft of the first motor 5, the driving rod 7 rotates, and then drives the second conical direction-changing gear 12 to rotate. Driven by the second conical direction-changing gear 12, the first conical direction-changing gear 10 rotates, and then the middle calendering roller 2 rotates in the opposite direction to the calendering roller 2 at one end and the auxiliary roller 3 at the other end. When the extension plate 4 contacts the film raw material, the extension plate 4 moves toward both ends of the auxiliary roller 3 under the action of extrusion, thereby actively driving the film to be flattened, thereby making the film able to extend more smoothly, which is more conducive to the discharge of internal gas from the film raw material, and then passes between the calendering rollers 2 for the final calendering forming. Driven by the output shaft of the second motor 6, the adjusting rod 8 can rotate, thereby moving the two adjusting plates 11, and driving the calendering roller 2 at one end and the auxiliary roller 3 at the other end to move relative to each other, adjusting the distance between them and the middle calendering roller 2, thereby making its adjustment more convenient.
