Description

Technical Field

[0001] The utility model relates to the field of tire production equipment, and more specifically, to a tread pressing wheel device. Background Art

[0002] As is well known, a tread is required in the process of producing a tire blank to prevent the carcass from being damaged, reduce road surface impact and vibration, and conduct the traction force and braking force of the wheel, which plays an important role during the operation of the tire. During the production process of the tire blank, when inspecting the quality of the tread joint, it is found that the two fixed points of the tread show an inward collapse phenomenon, resulting in gaps during the fitting and pressing of the tread, which affects the product quality. Since the automation level of the on-site molding machine is relatively high, the tread fitting is fully automated, with high production efficiency. Moreover, the collapse position is located inside, which is a blind spot in the field of vision of the molding machine operator and cannot be tracked and observed, so the abnormal collapse phenomenon cannot be processed in a timely manner, affecting the molding quality of the tire blank. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a tread pressing wheel device, which reduces the abnormal collapse phenomenon of the tread fitting, ensures the quality of the tread pressing, and realizes the high-quality molding production of the tire blank.

[0004] The technical solution adopted by the present utility model to solve its technical problems is as follows: A tread pressing wheel device is provided with a central conveyor belt. The feature is that symmetric left conveyor belt 1, left conveyor belt 2, right conveyor belt 1, and right conveyor belt 2 are arranged in parallel on both the left and right sides of the central conveyor belt. An input side roller shaft and an output side roller shaft are installed in parallel above the central conveyor belt, left conveyor belt 1, left conveyor belt 2, right conveyor belt 1, and right conveyor belt 2. An input side central left gear, an input side central right gear, an input side left gear 1, an input side left gear 2, an input side left gear 3, an input side right gear 1, an input side right gear 2, and an input side right gear 3 are installed on the input side roller shaft; the toothed sides of the input side central left gear and the input side central right gear are adjacent to each other, and the center line between them corresponds to the center line of the central conveyor belt; the toothed sides of the input side left gear 1 and the input side left gear 2 are adjacent to each other, and the center line between them corresponds to the center line of the left conveyor belt 1. The toothed side of the input side left gear 3 is located outside the center line of the left conveyor belt 2; the toothed sides of the input side right gear 1 and the input side right gear 2 are adjacent to each other, and the center line between them corresponds to the center line of the right conveyor belt 1. The toothed side of the input side right gear 3 is located outside the center line of the right conveyor belt 2; the toothed sides of the output side central left gear, the output side central right gear, the output side left gear 1, the output side left gear 2, the output side left gear 3, the output side right gear 1, the output side right gear 2, and the output side right gear 3 are all installed outward on the output side roller shaft. The center line between the output side central left gear and the output side central right gear corresponds to the center line of the central conveyor belt. The output side central left gear, the output side central right gear, the output side left gear 1, the output side left gear 2, the output side left gear 3, the output side right gear 1, the output side right gear 2, and the output side right gear 3 avoid the conveyor belt gaps.

[0005] The beneficial effect of the present utility model is that by changing the arrangement mode of the gears on the tread pressing roller, when the tread is attached to the belt drum, the material interface is smoothly pressed onto the crown strip material. It effectively reduces the abnormal collapse phenomenon of the tread material, improves the stability of the tread transmission, ensures the quality of the tread attachment, and realizes the high-quality forming production of the tire blank.
