Description
Technical Field
[0001] The utility model relates to the technical field of carbon fiber winding, in particular to a guide mechanism of a carbon fiber winding machine. Background Art
[0002] Carbon fiber is a fiber material composed of carbon elements. With its excellent properties such as high strength, light weight, corrosion resistance and high temperature resistance, carbon fiber is usually combined with matrix materials such as resin to make carbon fiber reinforced composite materials with excellent structural properties. The carbon fiber winding machine is a device specially used to wind carbon fiber bundles onto a substrate (such as a core shaft or mold) according to a specific trajectory.
[0003] When wrapping carbon fiber around the outside of a steel cylinder, existing carbon fiber winding machines usually install a guide mechanism between the carbon fiber bundle and the steel cylinder to ensure that the fiber bundle can be accurately wound along a predetermined trajectory and angle. Currently, the most common guide mechanism is to limit and guide through a fixed guide ring.
[0004] Although the guide ring can play a guiding role, its position is fixed and cannot be moved as needed. Since the guide ring is fixed, it cannot be flexibly adjusted according to the needs of the winding process. When the curvature of the cylinder surface changes, the guide ring cannot effectively adjust the position of the fiber bundle, resulting in the fiber bundle being overly concentrated in some areas and too sparse in other areas. This uneven fiber distribution directly affects the structural quality of the winding layer, thereby reducing the winding efficiency. Utility Model Content

Cleaning brushes 26 are installed on both sides of the guide ring 21. The cleaning brushes 26 are made of soft material. The cleaning brushes 26 are convenient for cleaning the dust on the outside of the carbon fiber. The driving wheel 4 is fixedly connected with a mounting rod 7 inside. The mounting rod 7 is externally mounted with a wire drum 8. The mounting rod 7 is convenient for installing the wire drum 8. The storage rod 9 is externally mounted with a steel cylinder. The storage rod 9 is convenient for installing the steel cylinder. The horizontal plate 10 is below. The bracket 1 is fixedly connected to a mounting ring 11, and the second motor 12 is fixedly connected to the inside of the mounting ring 11. The installation of the mounting ring 11 facilitates the fixation of the second motor 12. Grooves 20 are provided on both sides of the outside of the horizontal plate 10. The movable plate 18 is slidably connected to the inside of the two grooves 20. The grooves 20 facilitate the movement of the movable plate 18. A control panel 2 is installed on the outside of the bracket 1. The control panel 2 is electrically connected to the first motor 3 and the second motor 12. The control panel 2 is provided to facilitate the control of the opening and closing of the first motor 3 and the second motor 12.
[0028] Specifically, when carbon fiber winding is performed on the steel cylinder, first, the carbon fiber pay-off drum 8 is installed on the outside of the mounting rod 7. Next, one end of the carbon fiber bundle is passed through the inside of the guide ring 21. This step ensures that the carbon fiber can enter the winding process under the guidance of the guide ring 21. Subsequently, the carbon fiber bundle begins to be wound onto the outer surface of the steel cylinder, and the first motor 3 is started. After the first motor 3 is started, the output end of the motor drives the active wheel 4 fixed thereon to rotate, and the active wheel 4 transmits power to the driven wheel 6 through the connected belt 5. The driven wheel 6 causes the mounting rod 7 to start rotating through transmission. Since the carbon fiber pay-off drum 8 is fixed on the mounting rod 7, the rotation of the mounting rod 7 drives the carbon fiber winding drum to rotate together, so that the fiber bundle is gradually released from the winding drum. At the same time, the rotation of the driven wheel 6 also drives the placement rod 9 connected to it to rotate together, and the steel cylinder installed on the placement rod 9 also starts to rotate synchronously. As the steel cylinder rotates, the carbon fiber bundle will be wound around the outer surface of the steel cylinder layer by layer to form a winding layer, gradually covering the entire surface of the steel cylinder. At this time, the second motor 12 is started, and the start of the second motor 12 drives it The first transmission wheel 13 fixed on the output end rotates, and the first transmission wheel 13 is connected to the second transmission wheel 15 through the transmission belt 14, driving the second transmission wheel 15 to rotate synchronously. When the transmission belt 14 rotates, the fixed block 16 fixed thereon also starts to move. The movement of the fixed block 16 drives the fixed rod 17 fixed above to move synchronously. The movement of the fixed rod 17 causes the guide ring 21 to reciprocate left and right through the connected movable plate 18. When the movable plate 18 moves to the left to the outermost side of the transverse plate 10, the fixed rod 17 enters the guide groove 19 provided inside the movable plate 18, thereby causing the movable plate 18 to start moving to the right. The whole process is achieved through the coordinated action between the first transmission wheel 13, the transmission belt 14 and the second transmission wheel 15, driving the movable plate 18 to reciprocate left and right on the outside of the transverse plate 10. Through the movement of the guide ring 21, the carbon fiber bundle can cover all parts of the surface of the cylinder to form a uniform and tight winding layer. This uniform distribution not only improves the winding quality of the cylinder, but also greatly improves the winding efficiency, reduces fiber waste, and ensures the structural strength and consistency of the final product.
[0029] Reference Figure 2 、 Figure 3 and Figure 6, a disassembly assembly 22 is provided inside the guide ring 21, and the disassembly assembly 22 is used to replace the cleaning brushes 26 installed on both sides of the guide ring 21. The disassembly assembly 22 includes a cross bar 2201, which is fixedly connected to the inner sides of the guide ring 21. Both sides of the outer side of the cross bar 2201 are slidably connected with sliders 2202. The cross bar 2201 is provided to facilitate the movement of the two sliders 2202. The middle parts of the two sliders 2202 are fixedly connected with a return spring 2204, and the return spring 2204 is sleeved on the outside of the cross bar 2201. The upper parts of the two sliders 2202 are fixedly connected with a handle 2203. The handle 2203 is provided to facilitate the use of the operator. An L-shaped rod 2205 is fixedly connected to the outside, and the L-shaped rod 2205 is provided to facilitate fixing the cleaning brush 26. First through holes 23 are provided on both sides of the inside of the guide ring 21, and the two L-shaped rods 2205 are slidably connected to the inside of the two first through holes 23. The first through holes 23 are provided to facilitate the movement of the L-shaped rod 2205. A card slot 24 is provided inside the two cleaning brushes 26, and the two L-shaped rods 2205 are plugged into the two card slots 24, which improves the stability of the installation of the cleaning brush 26. A second through hole 25 is provided on the upper part of the guide ring 21, and the two handles 2203 are slidably connected to the inside of the second through hole 25. The second through hole 25 is provided to facilitate the movement of the handle 2203.
[0030] When installing the cleaning brush 26, first, when the two handles 2203 are moved relative to each other, the two sliders 2202 fixed at the lower part will be driven to move relative to each other along the outside of the cross bar 2201. During this process, the distance between the two sliders 2202 is gradually reduced, and the return spring 2204 fixed in the middle is squeezed, so that the return spring 2204 is subjected to the pressure from the slider 2202, resulting in deformation and accumulation of reaction force. At the same time, the L-shaped rods 2205 fixed outside the two sliders 2202 also move accordingly, so that the two L-shaped rods 2205 gradually move from the initial position to the inside of the two first through holes 23 reserved on the guide ring 21, preparing to install the cleaning brush next. When the L-shaped rods 2205 reach the position of the two first through holes 23, the two cleaning brushes 26 are then accurately inserted into the guide ring 21. , and then, after completing the insertion of the cleaning brush 26, the user can release the grip 2203. At this time, after the return spring 2204 is squeezed and released, it reacts to the slider 2202 through its accumulated elastic force, pushing the two L-shaped rods 2205 to move in the opposite direction. Under the action of the spring reaction force, the L-shaped rod 2205 is inserted into the two slots 24 on the cleaning brush 26. When the cleaning brush 26 is in place, it will continue to act during the fiber winding process. As the carbon fiber bundle passes through the guide ring 21, the cleaning brush 26 can efficiently clean the dust, impurities and other foreign matter that may affect the winding quality on the surface of the fiber bundle. The bristles of 26 are relatively soft, which can not only remove the fine particles on the fiber surface, but also will not damage the fiber, thereby ensuring that the fiber bundle always remains clean and complete during the winding process.
[0031] Working principle: When winding the steel cylinder, first, put the carbon fiber pay-off drum 8 on the outside of the mounting rod 7, then pass one end of the carbon fiber through the inside of the guide ring 21, and then wind the carbon fiber around the outside of the steel cylinder. At this time, start the first motor 3, and the first motor 3 rotates the driving wheel 4 fixed at the output end. The driving wheel 4 rotates and drives the driven wheel 6 to rotate through the belt 5. When the driving wheel 4 rotates, it drives the internally fixed mounting rod 7 to rotate. The mounting rod 7 rotates and drives the pay-off drum 8 fixed outside to rotate. At the same time, the driven wheel 6 drives the steel cylinder installed outside the storage rod 9 to rotate, thereby completing the winding of the carbon fiber. When winding, by starting the second motor 12, the second motor 12 drives the first transmission wheel 13 fixed at the output end to rotate. The first transmission wheel 13 rotates and drives the second transmission wheel 15 to rotate through the transmission belt 14. At the same time, when the transmission belt 14 rotates, it drives the external fixed fixed block 16 to move. When the movable plate 18 moves to the outermost part of the transverse plate 10, the fixed rod 17 moves in the guide groove 19 provided inside the movable plate 18, so that the movable plate 18 moves to the right side outside the transverse plate 10. Under the movement of the first transmission wheel 13, the transmission belt 14 and the second transmission wheel 15, the movable plate 18 and the upper fixed guide ring 21 can be reciprocated left and right outside the transverse plate 10, so that when the carbon fiber is wound on the steel cylinder, the guide ring 21 can reciprocate left and right. When the guide ring 21 reciprocates left and right, the fiber bundle can be evenly distributed on the surface of the steel cylinder, so as to prevent the fibers from being excessively concentrated in certain areas or being too sparse, thereby improving the winding quality and winding efficiency of the steel cylinder.
[0032] When installing the cleaning brush 26 inside the guide ring 21, first, move the handles 2203 relative to each other, and the two handles 2203 move relative to each other, and the two sliders 2202 fixed at the lower part move relative to each other outside the cross bar 2201. When the two sliders 2202 move relative to each other, the return spring 2204 fixed in the middle is squeezed, so that the return spring 2204 is deformed under the force, and at the same time, the two L-shaped rods 2205 fixed outside the two sliders 2202 move relative to each other, so that the two L-shaped rods 2205 move to the inside of the two first through holes 23. At this time, insert the two cleaning brushes 26 into the inside of the guide ring 21, and then release the two handles 2203. Under the reaction force of the return spring 2204, the two L-shaped rods 2205 can be inserted into the inside of the two card slots 24. This realizes that when winding the cylinder, a cleaning brush 26 is installed inside the guide ring 21 to remove dust and foreign matter on the surface of the fiber bundle, ensure the cleanliness of the fiber during the winding process, and improve the quality of the winding layer.
