[0030] like Figure 1 , Figure 2 and Figure 4 As shown, the support component 2 includes a cover plate keel 21, and the cover plate keel 21 is made of stainless steel. Stainless steel has good corrosion resistance and can resist the erosion of media such as gas, liquid and steam in the carding machine, thereby extending the service life of the keel. The cover plate keel 21 is provided with arched reinforcement ribs, which are beneficial to improving the deformation resistance of the cover plate keel, thereby improving the bearing capacity and bending resistance. The cover plate keel 21 is provided with a cavity 22, which can reduce the use of materials, thereby reducing the dead weight, reducing the load of the building structure, and strengthening the moment of inertia and section modulus, making it more sturdy and durable. The support component 2 is provided with a first arched reinforcement rib 261, a second arched reinforcement rib 262 and a third arched reinforcement rib 263, which can strengthen the cover plate keel 2 1 has good rigidity and anti-deformation ability. A front bottom support column 27 and a rear bottom support column 28 are arranged on both sides of the third arch reinforcement rib 263, and the wall thickness of the front bottom support column 27 is greater than that of the rear bottom support column 28, so that the center of gravity of the rotating cover plate can be moved forward, and the backward swing can be reduced when entering and leaving the combing area. A through groove 23 is opened on the side of the cover plate keel 21, and a carbon fiber rod 24 is arranged inside the through groove 23. The carbon fiber rod 24 is made of carbon fiber material, has a small thermal expansion coefficient, a small deformation, and can withstand a large load and pressure, thereby improving the overall strength and stability. The two ends of the cavity 22 are threaded with closed screws 25, which can seal the carbon fiber rod 24 to avoid being affected by the high temperature and high humidity environment in the carding machine, and ensure the original stress state of the carbon fiber rod 24.

[0031] like Figure 2 , Figure 3 and Figure 5 As shown, the connection component 3 includes a joint 31, which has two through holes 32, and steel rods 33 are respectively inserted into the through holes 32. The side walls of the joint 31 are fixedly connected with plug blocks 34, which are convenient for stably supporting the cover plate keel 21, improving the stability of the connection with the curved track 1, and facilitating disassembly and assembly.

[0032] Furthermore, a plurality of fixing screws 4 are threadedly penetrated through the upper surface of the support assembly 2 , which can limit the position of the carbon fiber rod 24 and prevent the carbon fiber rod 24 from shaking in the through groove 23 .

[0037] When the support assembly 2 is affected by the high temperature and high humidity in the carding machine, the flat plate keel 21 will be deformed and arched upward. At this time, the deformation of the flat plate keel is limited by increasing the prestress of the carbon fiber rod 24, so that the deformation of the flat plate keel is reduced, which can ensure the uniformity of the spacing and is more conducive to the uniform combing of the flat plate card clothing.

[0038] Under the combined effect of the two aspects, the support assembly 2 can always maintain a perfect initial state in a high temperature and high humidity environment, ensuring the consistent uniformity of precision, thereby improving the combing uniformity and stability.
