[0031] This embodiment provides a carbon fiber winding machine, see Figure 1-Figure 5 As shown, it includes a core mold 1, a base plate 2 is arranged below the core mold 1, a first bracket 21 is installed on the upper end surface of the base plate 2, both ends of the core mold 1 are rotatably connected with the first bracket 21 respectively, one end of the core mold 1 is transmission connected with the first motor 3, the first motor 3 is connected with the base plate 2 through the first support column 31, a slide rail 4 is opened on the upper end surface of the base plate 2, the slide rail 4 is arranged on one side of the core mold 1, the slide rail 4 is slidably connected with a slide plate 41, an impregnation chamber 42 and a second bracket 43 are arranged on the upper end surface of the slide plate 41, a winding roller 431 is installed on the top of the second bracket 43, a rotating roller 421 is installed in the impregnation chamber 42, a limiting groove 422 is arranged on the side of the impregnation chamber 42 close to the core mold 1, and a movable rod assembly 5 is connected to the side of the slide plate 41.
[0032] In the above embodiment, a bottom plate 2 is arranged below the core mold 1, and the bottom plate 2 is used to provide support for the winding machine, which is beneficial to improving the stability of the winding machine during operation. A first bracket 21 is installed on the upper end surface of the bottom plate 2, and the two ends of the core mold 1 are respectively connected to the first bracket 21 for rotation, and one end of the core mold 1 is connected to the first motor 3 for transmission. The first motor 3 can drive the core mold 1 to rotate at a uniform speed, and the carbon fiber filaments are wound and coated on the outer wall of the core mold 1 for curing and shaping. Among them, carbon fiber is wound on the winding roller 431, and the winding roller 431 is connected to the top of the second bracket 43 for rotation. The process of carbon fiber winding and molding on the mold core through the winding roller 431 is as follows: the carbon fiber passes through the rotating roller 421 in the impregnation chamber 42, and is impregnated with resin in the impregnation chamber 42, and then is wound on the core mold 1 through the limiting notch 422. The rotating roller 421 installed in the impregnation chamber 42 is used to change the movement path of the carbon fiber filaments, and guides the carbon fiber to the impregnation chamber 42 in the transmission state for full impregnation contact with the resin, which is beneficial to improve the impregnation efficiency of the carbon fiber. Furthermore, since a limiting groove 422 is provided on the side of the impregnation chamber 42 close to the core mold 1, the carbon fiber is wound on the core mold 1 through the limiting groove 422. The limiting groove 422 serves to limit and bundle the carbon fiber before winding, thereby preventing the carbon fiber from deviating during the winding process, which is beneficial to improving the uniformity and tightness of the carbon fiber winding. In addition, the extension and shortening of the movable rod assembly 5 connected to the side of the slide plate 41 can drive the carbon fiber to move along the axial direction of the core mold 1 during winding. When the core mold 1 rotates at a uniform speed, the thickness of the carbon fiber wound on the unit area of the core mold 1 can be controlled by controlling the movement speed of the slide plate 41 in the axial direction of the core mold 1. For example, the carbon fiber moves slowly along the axial direction during winding, so that the number of turns of the carbon fiber wound on the core mold 1 per unit time is large, and then the thickness of the carbon fiber wound on the unit area of the core mold 1 is thick. By controlling the reciprocating motion of the carbon fiber along the axis of the core mold 1 during winding, it is used to perform multi-layer winding on the core mold 1, and the number of winding layers of the carbon fiber on the core mold 1 can be controlled, so that the carbon fiber winding molding products meet different process requirements, which is beneficial to improving the quality of the finished products of carbon fiber winding molding.

Figure 2 For example, the second motor 521 drives the transmission gear 52 to rotate and drive the connecting rod 51 to move, and the movement of the connecting rod 51 can pull the slide plate 41 to move along the slide rail 4. Preferably, the second motor 521 can be a servo motor, and the speed of the connecting rod 51 can be controlled by controlling the rotation speed of the second motor 521, thereby controlling the movement speed of the slide plate 41 in the axial direction of the core mold 1, and controlling the rotation direction of the second motor 521 can control the movement direction of the slide plate 41 in the axial direction of the core mold 1, thereby realizing the reciprocating movement of the slide plate 41 in the axial direction of the core mold 1, which is beneficial to improving the winding efficiency of the carbon fiber on the core mold 1.
[0035] In one embodiment of the present application, refer to Figure 5 As shown, guide blocks 512 are provided on both sides of the connecting rod 51 .
[0036] In the above embodiment, the connecting rod 51 is arranged between the guide blocks 512. The guide blocks 512 limit the movement of the connecting rod 51 to prevent the connecting rod 51 from deviating during movement and thus affecting the smooth movement of the slide plate 41, which is beneficial to improving the stability of the carbon fiber winding.
[0037] In one embodiment of the present application, see Figure 4 As shown, the side of the impregnation cavity 42 close to the core mold 1 is provided with a plurality of limiting slots 422 , and the slot widths of the plurality of limiting slots 422 are different.
[0038] In the above embodiment, the limiting groove 422 plays a role in limiting and bundling the carbon fiber before winding, preventing the carbon fiber from deviating during the winding process. A plurality of limiting grooves 422 with different widths are provided to accommodate carbon fibers of different diameters, which is beneficial to improving the adaptability of the winding machine.
[0039] In one embodiment of the present application, see Figure 4 As shown, a heating rod 6 is installed on the side of the core mold 1.
[0040] In the above embodiment, the carbon fiber usually needs to be baked after impregnation and winding to solidify the resin and enhance the performance of the material. The heating rod 6 is used to bake the carbon fiber after impregnation and winding, which is beneficial to promote the full curing of the resin so that the carbon fiber impregnated material can meet the expected performance requirements.
[0041] In one embodiment of the present application, see Figure 4As shown, a protective cover 61 is provided on the side of the heating rod 6 .
[0042] In the above embodiment, the protective cover 61 arranged on the side of the heating rod 6 can prevent the heat of the heating rod 6 from being lost too quickly and effectively utilize the thermal energy. On the other hand, the protective cover 61 can prevent the staff from accidentally touching the heating rod 6 and causing injuries, which is beneficial to improving safety.
[0043] In one embodiment of the present application, see Figure 3 As shown, a pair of squeezing rollers 7 are installed on the upper part of the impregnation chamber 42.
[0044] In the above embodiment, the carbon fiber passes through two squeezing rollers 7, and the two squeezing rollers 7 extrude the impregnated carbon fiber. The pressure applied by the squeezing rollers 7 to the carbon fiber during the extrusion process can make the impregnated carbon fiber more tightly combined together, which is beneficial to increase the density and mechanical properties of the carbon fiber molding. In addition, the excess resin in the impregnated carbon fiber can be squeezed out during the extrusion process.
[0045] In the actual use of this application: Figure 1 As shown, the carbon fiber on the winding roller 431 is manually guided through the rotating roller 421, and then is wound on the outer surface through the limiting notch 422. One end of the core mold 1 is connected to the first motor 3 for transmission. The first motor 3 is turned on to drive the core mold 1 to rotate at a uniform speed. The rotation of the core mold 1 has a traction and pulling effect on the carbon fiber. The carbon fiber passes through the rotating roller 421 in the impregnation chamber 42, and is impregnated with resin in the impregnation chamber 42, and then is wound on the core mold 1 through the limiting notch 422. The rotating roller 421 installed in the impregnation chamber 42 is used to change the movement path of the carbon fiber filament, and the carbon fiber is guided to the impregnation chamber 42 in a transmission state for sufficient impregnation contact with the resin. The limiting groove 422 set on the side of the impregnation cavity 42 close to the core mold 1 is wound on the core mold 1. The limiting groove 422 plays a role in limiting and bundling the carbon fiber before winding, preventing the carbon fiber from deviating during the winding process. When the core mold 1 rotates at a uniform speed, the thickness of the carbon fiber wound on a unit area of the core mold 1 can be controlled by controlling the movement speed in the axial direction. By controlling the reciprocating movement of the carbon fiber along the axis of the core mold 1 during winding, the core mold 1 can be used for multi-layer winding. The number of winding layers of the carbon fiber on the core mold 1 can be controlled, so that the carbon fiber winding molded product meets different process requirements. The present application is suitable for cylindrical mold cores to wind the carbon fiber into a carbon fiber tube.
