Description

Technical Field

[0001] This utility model relates to the technical field of aircraft tires, and in particular to an automatic pressing device for the belt layer of a rubber aircraft tire. Background Technology

[0002] Aircraft tires are the core component of aircraft landing gear, and their design and performance are directly related to flight safety. Aircraft tires are usually made of high-strength rubber, nylon or aramid fiber, and the tire carcass structure contains multiple layers of cord to withstand high pressure and impact.

[0003] Existing automatic belt layer pressing devices, such as the one disclosed in utility model patent application number 202122622390.4, mainly include a worktable. Rotatable pressure rollers are evenly arranged inside the worktable. A telescopic rod is positioned opposite each other at the upper end of the worktable, and a support plate is positioned opposite each other at the lower end of the connecting plate. Each of the two opposing support plates has a rotatably connected adjustment device. A drive motor is mounted on the horizontal plate. In use, the belt layer pressure rollers of different sizes are first adjusted and replaced according to the width of the tire belt layer. Then, the screws rotate within the threaded holes. During rotation, both screws rotate simultaneously, driving the tire shoulder pressure roller to move closer to the tire shoulder pressure roller. A locking block is installed in a slot, and then a fixing nut is used to rotate the device closer to the rotating shaft for fixation.

[0004] However, most existing pressing devices do not position the two sides of the belt layer, making it easy for the belt layer to deviate during the pressing process. Moreover, most existing pressing devices use a single roller to press, resulting in poor pressing effect and easy stress concentration in the belt layer. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an automatic pressing device for rubber aircraft tire belt layers that not only prevents the belt layer from deviating during movement and ensures the pressing effect of the belt layer, but also heats the belt layer and gradually increases the pressure to avoid stress concentration in the belt layer.

When the driving mechanism is activated, it drives the feeding and discharging mechanisms to rotate synchronously. The feeding and discharging mechanisms cooperate to feed the belt layer and prevent the belt layer from deviating during movement. The heating mechanism heats the belt layer and cooperates with the pressing mechanism to press the rubber aircraft tire belt layer.
