Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of looms, in particular to a loom for preparing carbon fiber cloth. Background Art
[0002] Carbon fiber reinforcement cloth is a unidirectional carbon fiber reinforcement product, usually woven with 12K carbon fiber yarn, and the carbon fiber cloth is prepared by a weaving machine. The weaving machine drives the carbon fibers to be arranged crosswise with each other, thereby improving the production efficiency of the carbon fiber cloth, and therefore it is widely used.
[0003] Specifically, when preparing carbon fiber cloth, the traction device in the loom is used to drive the carbon fiber to extend to the inside of the loom, and the longitudinal carbon fibers are arranged in a cross-staggered manner. The head of the machine drives the transverse carbon fibers to be interspersed between the staggered carbon fibers. Through the cross-arrangement, the carbon fiber cloth can be driven for preparation. However, when the carbon fiber is towed and transported, the traction device will drive the carbon fiber to move up and down, and when the carbon fiber moves up and down, it will cause the carbon fiber to become loose as a whole. When the carbon fiber is loose, wrinkles and other problems will appear after the carbon fiber cloth is prepared. For this reason, we propose a loom for preparing carbon fiber cloth.

The outer part of the second limiting sleeve 7 is sleeved with a spring 10 and installed with a roller 9. The roller 9 provides elastic buffering force when driving the carbon fiber 11 to move. The outer part of the roller 9 is sleeved with carbon fiber 11, and the inner part of the first slide bar 14 is movably sleeved with a side positioning plate 15. The front end of the connecting plate 3 is fixedly connected with a limiting plate 16, and the limiting plate 16 drives the carbon fiber 11 to extend and fix the position. The side of the bracket 1 is fixedly connected with a second slide rail 17, and the upper end of the second slide rail 17 is movably sleeved with a loom head 18. The loom head 18 drives the transverse carbon fiber to limit and pushes the carbon fiber to move between the mutually dislocated carbon fibers 11, and drives the carbon fiber cloth to be woven.
[0024] See also Figure 2 The connecting plate 3 is installed at the upper and lower ends of the first limiting sleeve 2, and the telescopic rods 4 installed on the inner side of the connecting plate 3 are staggered. The connecting plate 3 is installed at the upper and lower parts of the first limiting sleeve 2, and the telescopic rods 4 installed on the inner side of the connecting plate 3 are staggered. At the same time, the movable sleeve 5 drives the carbon fiber to be staggered. At the same time, the auxiliary carbon fiber is moved between the mutually staggered carbon fibers by the machine head, and then the carbon fiber cloth can be driven for weaving.
[0025] See also Figure 2 The middle part of the telescopic rod 4 is movably sleeved on the outside of the first limiting sleeve 2, and a circular hole is opened inside the movable sleeve 5. The telescopic rod 4 is movably sleeved on the inside of the first limiting sleeve 2, and the telescopic rod 4 drives the movable sleeve 5 to be telescoped up and down as a whole, and then the upper and lower layers of carbon fibers can be dislocated.

[0026] See also Figure 3 and Figure 4, one group of rollers 9 and springs 10 are installed on the upper part of the second limiting sleeve 7 and two groups are installed on the lower part. The carbon fiber 11 passes through the auxiliary positioning rod 8 and is sequentially sleeved on the outside of the three groups of rollers 9.

When the woven carbon fiber cloth moves between the extrusion roller 12 and the winding roller 13, the position of the side positioning plates 15 inside the first slide bar 14 is adjusted, and then the side positioning plates 15 level the two sides of the carbon fiber cloth. At the same time, after the carbon fiber cloth is wound around the outside of the winding roller 13, the winding roller 13 winds up the carbon fiber.
[0029] See also Figure 1 Two groups of extrusion rollers 12 are installed, and the carbon fiber 11 is sleeved on the outside of the two groups of extrusion rollers 12. At the same time, the carbon fiber 11 is wound on the outside of the winding roller 13. The carbon fiber cloth is extruded and positioned by the two groups of extrusion rollers 12 to improve the flatness of the carbon fiber surface and avoid the relaxation of the carbon fiber.
[0030] Working principle: When in use, the carbon fiber 11 is passed through the auxiliary positioning rod 8 and is sequentially sleeved on the outside of the roller 9. At the same time, the roller 9 extends to the inside of the movable sleeve 5. At the same time, the upper and lower groups of telescopic rods 4 sequentially drive the movable sleeve 5 to extend, and then the adjacent carbon fibers 11 are arranged in a staggered direction. At the same time, the loom head 18 is used to drive the auxiliary carbon fibers to be interspersed between the staggered carbon fibers, and the limiting plate 16 limits the moving trajectory of the carbon fibers. At the same time, after the carbon fiber cloth is prepared, the extrusion roller 12 produces the prepared carbon fiber cloth, and the winding roller 13 drives the carbon fiber cloth to be wound.
