AI Technical Summary
Traditional metal carding fabrics have high maintenance costs due to the integrated molding or welding of the toothed needles and needle plate. The sliding connection structure lacks precise positioning, which can cause the toothed needles to move around or fall off, affecting the carding effect and yarn quality.
The sliding connection structure of the mounting groove and the fixing groove, combined with the insertion rod positioning and spring buffer, realizes the detachable and precise positioning of the toothed needle and the needle plate. The axial movement is prevented by the hole-shaft cooperation between the insertion rod and the insertion hole and the limiting flange of the support plate. The spring absorbs vibration energy and ensures that the fiber is subjected to uniform force.
Reduce maintenance costs, prevent toothed needles from loosening and falling off, improve yarn quality, reduce neps and short fibers, and ensure stable equipment operation.

Abstract
Claims
1. A semi-curved top metal clothing with pressure resistance, comprising a curvedly arranged needle plate (1), characterized in that: The outer arc surface of the needle plate (1) is provided with an installation groove (2) extending along its arc length. The needle plate (1) is provided with a fixing groove (6) at equal intervals along its arc length. A fixing seat (4) is slidably connected in each fixing groove (6). A toothed needle (3) is integrally formed on the upper end of the fixing seat (4). Support plates (5) are symmetrically arranged on both sides of the fixing seat (4). Insertion holes (8) are provided at equal intervals along its arc length on the bottom surface of the needle plate (1). A positioning hole (9) is provided at the bottom of each set of fixing seats (4), and it is on the same axis as the adjacent insertion hole (8). A plug rod (7) is inserted into the insertion hole (8) and slides into the positioning hole (9). The top of the toothed needle (3) is a semi-arc tooth tip. The semi-arc tooth tip is formed by the tangent of the outward convex main arc and the transition arc. The included angle of the transition area of the two arcs is 65°~75°.
2. The semi-curved top metal clothing with compression resistance according to claim 1, characterized in that: The support plate (5) and the fixed seat (4) are integrally formed. The outer walls on both sides of the fixed seat (4) are provided with limiting flanges. The end of the insertion rod (7) is fixedly connected to a sliding plate (11).
3. The semi-curved top metal clothing with compression resistance according to claim 2, characterized in that: The outer wall of the insertion rod (7) is fitted with a spring (10), and the two ends of the spring (10) are fixedly connected to the top of the positioning hole (9) and the end face of the slide plate (11), respectively.
4. The semi-curved top metal clothing with compression resistance according to claim 3, characterized in that: The end of the support plate (5) away from the fixed seat (4) is bent toward the bottom surface of the needle plate (1) to form an auxiliary support part.
5. The semi-curved top metal clothing with compression resistance according to claim 4, characterized in that: The auxiliary support part abuts against the bottom surface of the needle plate (1) and acts to share the radial pressure on the toothed needle (3).
