Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof tires, in particular to a rubber material filling device for explosion-proof tires. Background Art

[0002] In modern transportation, especially in the field of commercial and military vehicles, the use of run-flat tires is becoming more and more widespread. Run-flat tires can continue to run a certain distance after the tire is punctured or otherwise damaged, thereby ensuring the safety of the vehicle and its passengers. Such tires usually need to be filled with special rubber compounds that can provide additional support, allowing the tire to carry weight and continue to travel even after losing some or all of its inflation pressure.

[0003] However, the existing explosion-proof tire rubber filling technology has some defects and limitations. For example, the traditional rubber filling method often cannot ensure that the rubber is evenly distributed inside the tire, which may cause unbalanced operation of the tire and reduce the driving stability and comfort of the vehicle.

[0009] Furthermore, the rotating shaft on the dual-shaft motor passes through the bottom of the material trough and is connected to a stirring shaft.

[0010] Furthermore, the surface of the stirring shaft is connected with stirring blades.

[0011] The advantages of the utility model are: through three independent glue spray heads, these glue spray heads rotate through the joint meshing of the planetary gear and the sun gear, it can ensure that the rubber is evenly and comprehensively distributed inside the explosion-proof tire, so that the rubber evenly covers the inner wall of the tire, thereby enhancing the explosion-proof performance and durability of the tire. The dual-axis motor is not only used to drive the gear system, but also connected to the stirring shaft and stirring blades, which can ensure the uniformity of the rubber before spraying, which is particularly important to prevent the rubber from solidifying or stratifying during heating and moving, and ensure the filling quality and consistency.
