AI Technical Summary
Traditional unwinding methods require a long space, which makes operation inconvenient. At the same time, short insertion rods cause instability of the axis, affecting the weaving quality of the yarn.
The unwinding drum is installed using a chuck assembly, with dual positioning using a conical connector and a positioning cone. The stability of the unwinding drum is ensured by a sliding rod and a clamping spring, eliminating the need for a long insert rod.
Without taking up too much space, the stable installation and smooth rotation of the unwinding drum are ensured, which improves the stability and quality of yarn weaving.

A carbon fiber braiding roving unwinding device characterized by: It includes a frame (1) and several unwinding drums (2); the unwinding drums (2) are provided with connectors (3) at both ends, the connectors (3) are in the shape of a frustum of a cone, and the frustum of the cone is provided with a concave conical groove (4); The frame (1) is provided with a number of clamping assemblies corresponding to the number of unwinding drums (2). The unwinding drums (2) are installed on the frame (1) through the clamping assemblies. The clamping assemblies include two conical clamps (5) that are adapted to the connectors (3). The center of each clamp (5) is provided with a positioning cone (6) that is adapted to the conical groove (4). Of the two clamps (5), one is a fixed head (7) and the other is a movable head (8). The two connectors (3) at both ends of the unwinding drum (2) are located in the two clamps (5) to form an installation.
2. The carbon fiber braiding roving unwinding device according to claim 1, characterized in that: The clamp assembly also includes a sliding rod (9) parallel to the axis of the two clamps (5). One end of the sliding rod (9) corresponding to the fixed head (7) passes through the frame (1) and forms a sliding fit with the frame (1). The end of the sliding rod (9) is provided with a rod head (10). A compression spring (11) is provided on the sliding rod (9) between the rod head (10) and the frame (1). The other end of the sliding rod (9) is provided with a short plate (12). The fixed head (7) and the movable head (8) are respectively installed on the frame (1) and the short plate (12) through a short shaft (13). The short shaft (13) forms a rotational fit with the short plate (12) and the frame (1).
3. The carbon fiber braiding roving unwinding device according to claim 2, characterized in that: The short plate (12) is provided with a handle (14) on the side facing away from the unwinding drum (2).
4. The carbon fiber braiding roving unwinding device according to claim 3, characterized in that: A guide tube (15) is provided on the frame (1) at a position opposite to the sliding rod (9), and the sliding rod (9) passes through the guide tube (15).
