Description

Technical Field

[0001] This utility model relates to the technical field of aircraft tires, and in particular to a device for cutting the corrugated protective layer of aircraft tires. Background Technology

[0002] The carcass material is the main load-bearing component of an aircraft tire, bearing the pressure of inflation, load, and various stresses generated during operation. The performance of the carcass material directly affects the overall performance of the aircraft tire. The corrugated protective layer is a special component used on aircraft tires, which can significantly improve the puncture resistance of aircraft tires and enhance their overall performance.

[0003] Existing aircraft tire corrugated protective layer cutting devices, such as the aircraft tire belt layer cutting device disclosed in utility model patent application number 202321654504.6, mainly include a base and a support platform. The support platform is installed on the right side of the top of the base, and a conveying device is set on the left side of the top of the base. The conveying device is used to convey the belt layer from left to right, and a cutting device is set in the middle of the top of the base. The cutting device is used to cut the belt layer. In use, when the front end of the belt layer moves between two sets of laser sensors, the two sets of laser sensors sense the belt layer and send a signal to the cutting device through the controller, so that the cutting device cuts the belt layer.

[0004] However, most existing cutting devices use straight-bladed cutters for cutting, which can easily cause deformation of the corrugated structure. Moreover, the corrugated protective layer is often not fixed during cutting, making it easy for the cutting process to deviate. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an aircraft tire corrugated protective layer cutting device that not only enhances the cutting effect by using laser cutting and avoids deformation of the corrugated structure, but also guides and fixes the thermal insulation protective layer during the conveying and cutting process to prevent the protective layer from deviating.

[0006] This utility model discloses a device for cutting the corrugated protective layer of an aircraft tire, comprising a conveying mechanism; it also includes two sets of guiding mechanisms, a driving mechanism, two sets of pressing mechanisms, and a cutting mechanism.

Both sets of pressing mechanisms are mounted on the conveying mechanism and fix the protective layer. The cutting mechanism is mounted on the conveying mechanism and cuts the protective layer. The conveying mechanism drives the corrugated protective layer of the aircraft tire forward. The two sets of guiding mechanisms limit and guide both sides of the protective layer to prevent it from deviating during conveying. After being conveyed to the designated position, the driving mechanism is activated, which drives the two sets of pressing mechanisms to rotate and fix and press the protective layer. Then, the cutting mechanism performs laser cutting on the protective layer.

The top ends of the two sets of side baffles are connected to the bottom ends of the two sets of sliders. According to the width of the corrugated protective layer, the power box drives the bidirectional lead screw to rotate, and the bidirectional lead screw drives the two sets of sliders to move closer together, so that the two sets of side baffles can abut against both sides of the protective layer and limit and guide the corrugated protective layer.

[0010] Preferably, the pressing mechanism includes a rotating shaft, a transmission gear, two sets of connecting plates, and a pressing roller. The rotating shaft is rotatably mounted on a bracket, and the transmission gear is mounted on the rotating shaft. The transmission gears on the two sets of pressing mechanisms mesh with the driving gear and the driven gear, respectively. Both sets of connecting plates are mounted on the rotating shaft, and the pressing roller is mounted on the two sets of connecting plates. The driving gear and the driven gear mesh with the transmission gears on the two sets of pressing mechanisms, respectively. The two sets of transmission gears drive the two sets of rotating shafts to rotate, and the rotating shaft drives the pressing roller to press the corrugated protective layer downward through the two sets of connecting plates, thus preventing the protective layer from deviating during the cutting process.
