Description

Technical Field

[0001] This utility model relates to the technical field of aircraft tire production, and in particular to a fiber cord impregnation and thermal stretching device. Background Technology

[0002] During the tire manufacturing process, a fiber cord layer needs to be installed on the tire. This layer forms the skeleton of the pneumatic tire and is composed of several layers of plastic cord fabric. These cord fabrics are usually made of cord materials with high strength, low elongation, and excellent fatigue resistance.

[0003] Existing fiber cord impregnation and thermal stretching devices, such as the tire cord impregnation equipment disclosed in utility model patent application number 202321839105.7, mainly include an impregnation tank, an adjustment component, and a drive component. The impregnation tank has a cavity at its right end, with mounting plates on both the front and rear inner walls of the cavity. A guide roller is rotatably connected between the two mounting plates and is located at the lower end of the cavity. A drying chamber is located on the left end of the upper surface of the impregnation tank. A fan is fixedly installed on the inner wall of a through hole in the middle of the top plate of the drying chamber. Through holes are provided in the middle of the left and right side walls of the drying chamber. In use, the tire cord is immersed in the glue inside the cavity under the guidance of the guide roller. As the tire cord moves to the left, a scraper removes excess glue from the upper and lower surfaces of the tire cord. A microcontroller controls the operation of the fan and the heating wire. The heating wire is energized and heats the surrounding air. The fan blows the heated air onto the tire cord, drying the tire cord.

[0004] However, most existing impregnation devices rely on the glue to naturally penetrate into the fabric, resulting in poor impregnation effect, long impregnation time, and the fabric is easily torn during subsequent heat stretching, affecting the stretching effect of the fabric. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a fiber curtain impregnation and heat stretching device that not only enhances the impregnation effect of the curtain fabric by stirring and filtering the adhesive, but also facilitates uniform heat stretching of the curtain fabric by setting the temperature and speed of the temperature control roller in a stepped manner, thus avoiding the curtain fabric being pulled and damaged.

[0006] This utility model discloses a fiber curtain impregnation and thermal stretching device, comprising an impregnation mechanism; it also includes a stirring mechanism, a spraying mechanism, a traction mechanism, and a stretching mechanism. The stirring mechanism is installed on the impregnation mechanism to stir the adhesive; the spraying mechanism is installed on the impregnation mechanism to spray the curtain; the traction mechanism is installed on the impregnation mechanism to traction the curtain; and the stretching mechanism is installed on the impregnation mechanism to thermally stretch the curtain.
