Description
Technical Field
[0001] The utility model relates to the technical field of carbon fiber broadening silk looms, and particularly relates to a constant-tension wire releasing frame for an ultra-thin carbon fiber loom. Background Technique
[0002] The ultra-thin carbon fiber broadening silk fabric overcomes the problems of many fabric surface intersection points and large fiber curling degree of traditional carbon fiber fabrics. Therefore, when preparing carbon fiber composite products using the carbon fiber broadening silk fabric, defects of the products caused by fiber aggregation at the fiber intersection points can be reduced, and the mechanical properties of the products can be improved.
[0003] However, during the production process of ultra-thin carbon fiber broadening silk fabrics, unstable warping tension of the warp yarns easily causes deformation of the carbon fiber fabric surface, affecting the use of the products. At present, the common rapier loom wire releasing frame often uses a spring pressing device to provide tension for the warp yarns, but this method cannot provide a constant tension, and instead will cause the original tension fluctuation range of the warp yarns to expand, which is not suitable for the production process of ultra-thin carbon fiber broadening silk fabrics.
[0004] Based on this, it is necessary to study a constant-tension wire releasing frame for an ultra-thin carbon fiber loom. Content of the Utility Model

Four groups of second sliders 6 are slidably arranged at intervals up and down on each second slide rail 5. The left and right ends of the wire feeding disk frame 2 are respectively screwed to the two groups of second sliders 6 corresponding to the left and right. A total of eight groups of wire feeding disk frames 2 are provided. Each wire feeding disk frame 2 can be adjusted up and down through the second slider 6 and the second slide rail 5, and the position is fixed by a locking member. In other embodiments, the number of the wire feeding disk frame 2, the second slide rail 5, and the wire feeding disk assembly 3 can be set differently according to actual production requirements.
[0038] As Figure 3 , multiple groups of wire feeding disk assemblies 3 are arranged at intervals left and right on the wire feeding disk frame 2. The wire feeding disk assembly 3 includes a mounting frame 301, a disk mounting roller 302, a warp yarn disk 303, a magnetic powder clutch 304, an isolation column 305, and a coupling 306.

The magnetic powder clutch 304 can provide adjustable damping for the disk mounting roller 302. A torque controller is integrally arranged in the magnetic powder clutch 304, which can automatically adjust the damping value according to the tension condition of the warp yarn, so that the warp yarn maintains a constant tension. The structure and principle of the magnetic powder clutch 304 are mainly prior art and will not be elaborated here.
[0039] The warp yarn bobbin 303 is sleeved on the bobbin mounting roller 302. A fixed key is provided between the bobbin mounting roller 302 and the warp yarn bobbin 303, enabling the warp yarn bobbin 303 to rotate together with the bobbin mounting roller 302 to avoid slipping.

Regarding the drawing of the warp yarn, it is mainly carried out by the next-level or other process equipment.
