Description

Technical Field

[0001] This utility model relates to the technical field of tire manufacturing, and in particular to a steel cord straightener for aircraft tires. Background Technology

[0002] Steel cord is one of the materials used in tire skeletons. During the processing of steel cord, it needs to be straightened. Because the straightness of steel cord changes due to the winding wheel when it is wound up, it is necessary to straighten the steel cord before it is used.

[0003] Existing straighteners for steel cord in aircraft tires, such as the one disclosed in utility model patent application number 202323110460.3 for engineering tires, mainly include a second straightening wheel, of which multiple second straightening wheels are provided. A first straightening wheel is movably arranged above the multiple second straightening wheels. A compression mechanism is arranged above the first straightening wheel. The compression mechanism includes an inverted U-shaped frame and a spring. Slider blocks are arranged at both ends of the inverted U-shaped frame. In use, the first straightening wheel is moved down by the downward movement of the inverted U-shaped frame, thereby changing the straightness of the steel cord during the straightening process, thus offsetting the straightness effect on the steel cord during winding.

[0004] However, most existing straighteners only straighten once, which makes them prone to rebound. Moreover, the straighteners are easily worn due to prolonged friction with the steel cord, affecting the service life of the device. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a steel cord straightener for aircraft tires that not only enhances the straightening effect of steel cord through two straightening processes to prevent the steel cord from rebounding and bending, but also allows the application of lubricating oil to the steel cord to reduce friction between the steel cord and the straightening roller, thereby extending the service life of the device.

[0006] This utility model discloses a steel cord straightener for aircraft tires, comprising a support mechanism, a conveying mechanism, a heating mechanism, an oiling mechanism, a pressing mechanism, and a straightening mechanism. The conveying mechanism is mounted on the support mechanism and drives the steel cord forward. The heating mechanism is mounted on the support mechanism and heats the lubricating oil. The oiling mechanism is mounted on the heating mechanism and applies the lubricating oil to the steel cord. The pressing mechanism is mounted on the support mechanism and pre-straightens the steel cord. The straightening mechanism is mounted on the support mechanism and straightens the steel cord. The operator inserts the steel cord into the support mechanism, the conveying mechanism continuously conveys the steel cord forward, the heating mechanism heats the lubricating oil, the oiling mechanism applies the heated lubricating oil to the steel cord, the pressing mechanism pre-straightens the steel cord to eliminate the original curvature, and then the straightening mechanism completely straightens the steel cord to prevent it from rebounding.

Starting the motor causes the conveying roller and rubber sleeve to rotate, and the rubber sleeve drives the steel cord forward.
