[0028] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0029] Example 1

[0030] In a typical embodiment of this utility model, such as Figure 1 As shown, a cover plate skeleton is proposed, including: a skeleton body 1 and an end body 2. The lower end face of the skeleton body 1 is provided with a slot 13 for inserting the end body 2. The slot 13 has a necked structure at both ends and passes through both ends of the skeleton body 1. The end body 2 is detachably connected to the skeleton body 1 by insertion. Both ends of the end body 2 extend outward from the skeleton body 1, and the end body 2 is bonded and fixed to the skeleton body 1 to limit the skeleton body 1 and the end body 2 to prevent separation between the skeleton body 1 and the end body 2.

[0031] Specifically, the main body 1 of the skeleton includes a back 11 and a needle cloth support 12. The back 11 is fixedly connected to the needle cloth support 12 by integral molding. The back 11 is fixedly installed on the upper end face of the needle cloth support 12. A slot 13 is provided on the lower end face of the needle cloth support 12. The two ends of the slot 13 penetrate through the two end faces of the needle cloth support 12. The end body 2 is inserted into the slot 13.

[0032] In this embodiment, both the main body 1 and the end body 2 are made of metal. In other embodiments, the main body 1 and the end body 2 can also be made of composite materials such as carbon fiber and epoxy resin to improve their lightweight and fatigue resistance.

[0033] The back 11 of the main frame 1 is a hollow structure with a cavity 14 inside to reduce the overall weight of the main frame 1. A reinforcing rib 15 is fixed inside the cavity 14. The cross-section of the reinforcing rib 15 is T-shaped to improve the deformation resistance of the back 11 in the lateral and vertical directions and reduce the risk of thermal deformation of the main frame 1.

[0034] like Figure 2 As shown, the end body 2 includes a first insertion part 21, a second insertion part 22, and an end part 23. The first insertion part 21, the second insertion part 22, and the end part 23 are fixedly connected together by integral molding. There is one first insertion part 21 and two second insertion parts 22. The two second insertion parts 22 are fixedly disposed at opposite ends of the first insertion part 21. Both the first insertion part 21 and the second insertion part 22 are plate-shaped structures for insertion into the slot 13. The width of the second insertion part 22 is smaller than that of the first insertion part 21. A variable cross-section structure is formed, which can cooperate with the slot 13 to form a snap-fit ​​limit. The overall shape of the slot 13 is the same as the combined shape of the first insertion part 21 and the second insertion part 22. There are two ends 23. Each end of the second insertion part 22 away from the first insertion part 21 is fixedly connected to an end 23. The end 23 extends outward from the slot 13. The lower end face of the end 23 is fixedly installed with a toe unit 3. The toe unit 3 is made of wear-resistant materials such as silicon nitride ceramic sheet. The toe unit 3 has a toe surface that contacts the carding machine slide rail.

[0035] The first insertion part 21 and the second insertion part 22 have the same thickness, and the thickness of the first insertion part 21 and the second insertion part 22 is greater than that of the end 23. The thickness of the first insertion part 21 and the second insertion part 22 is the same as the depth of the slot 13, so that the lower end face of the first insertion part 21 and the second insertion part 22 is flush with the lower end face of the needle cloth support part 12, and then they are combined to form a needle cloth support surface for supporting the needle cloth.

[0036] like Figure 2 As shown, a connecting hole 24 is provided on the end 23. The axial direction of the connecting hole 24 is perpendicular to the axial direction of the end 23. The connecting hole 24 penetrates the end 23 along the thickness direction of the end 23 for connection with the transmission chain of the drive mechanism.

[0037] A bell-toe unit 3 is fixedly connected between the lower end faces of the two ends 23. The bell-toe unit 3 is inserted into the first insertion part 21 and the second insertion part 22. Specifically, the first insertion part 21 and the second insertion part 22 are provided with mounting holes 25. The mounting holes 25 extend along the length direction of the first insertion part 21 and the second insertion part 22 and penetrate through the first insertion part 21 and the second insertion part 22 for mounting the bell-toe unit 3. The mounting holes 25 extend to the lower end face of the end 23 and form a groove at the lower end face of the end 23. The bell-toe unit 3 is partially embedded in the groove. The bell-toe unit 3 protrudes outward from the lower end face of the end 23, and the remaining part of the bell-toe unit 3 is inserted into the mounting holes 25. The bell-toe unit 3 is fixedly connected to the end body 2 by adhesive. When the bell-toe unit 3 is damaged, a new bell-toe unit 3 can be replaced without replacing the entire end body 2, thereby reducing the cost of use.

[0038] The bell-toe unit 3 extends from one end 23 of the end body 2 to the other end 23. While serving as a bell-toe structure, it can also improve the overall strength of the end body 2 and the skeleton body 1. At least two bell-toe units 3 are provided. The bell-toe unit 3 is a rod-shaped or block-shaped structure.

[0039] like Figure 5 As shown, the interior of the end body 2 is also filled with a buffer layer 26, which is a honeycomb foam aluminum that can effectively absorb energy and reduce vibration, reduce the transmission of vibration, prevent the cover plate frame from being damaged by alternating stress, and avoid fatigue cracks in areas of stress concentration.

[0040] like Figure 3 As shown, slot 13 is a variable cross-section slot structure. The slot width for installing the first insert part 21 is larger than the slot width for installing the second insert part 22. To reduce stress concentration, as... Figure 4 As shown, the groove end for installing the first insert part 21 is an arc-shaped surface. At this time, the end of the corresponding first insert part 21 is also arc-shaped. In this way, the transition of the curved surface is achieved through the cooperation of the convex and concave curved surfaces, reducing stress concentration and improving the overall service life of the cover plate frame.

[0041] Example 2

[0042] In another typical embodiment of this utility model, a carding machine is proposed, which adopts the cover plate skeleton mentioned in Embodiment 1, and the conveyor belt of the carding machine is connected to the first connecting hole 24 on the end 23.
