Description

Technical Field

[0001] This invention relates to the field of winding machine technology, and specifically to a simple device that can convert a three-axis winding machine into a four-axis winding machine. Background Technology

[0002] Composite material winding is a composite material molding process suitable for manufacturing rotating body products. It involves winding reinforcing materials onto a mandrel according to a specific pattern, ultimately producing high-performance products with high strength, lightweight, and good corrosion resistance. These products are widely used in high-end equipment fields such as aerospace and energy equipment.

[0003] In composite material winding molding processes, the winding machine is an essential and crucial component. The performance of the winding machine largely determines the performance of the finished composite material. Traditional three-axis winding machines cannot meet the requirements for winding at various angles. When the winding angle is small, fibers tend to accumulate at one corner of the nozzle, resulting in poor fiber spreading and fiber damage. Although four-axis or higher winding machines can meet more winding angle requirements compared to three-axis machines, their purchase, operating, and maintenance costs are all higher.

[0004] Therefore, it is urgent to improve the traditional triaxial winding machine to address the problem that the triaxial winding machine cannot meet the technical requirements of small-angle winding, while improving the fiber spreading effect, enhancing equipment performance and product quality. Summary of the Invention

[0005] The purpose of this invention is to provide a simple device that can convert a three-axis winding machine into a four-axis winding machine, in order to solve the problem that existing traditional three-axis winding machines cannot meet the requirements of winding at multiple angles.

[0006] To achieve the above objectives, the present invention provides a simple device for converting a three-axis winding machine into a four-axis winding machine, comprising an outer frame, a terminal nozzle, a front yarn separating guide, and a middle rotating drum; the terminal nozzle and the front yarn separating guide are disposed opposite to each other at both ends of the middle rotating drum, and the middle rotating drum is rotatably connected to the outer frame; the middle rotating drum has a yarn channel inside for yarn to pass through, and the two ends of the yarn channel are open and face the terminal nozzle and the front yarn separating guide respectively.

[0007] In a preferred embodiment of this application, the outer frame is provided with a mounting part, and the middle rotating cylinder is rotatably engaged with the mounting part.

[0008] In a preferred embodiment of this application, the mounting part is provided with a bearing corresponding to the middle rotating cylinder, and the middle rotating cylinder is rotatably engaged with the mounting part through the bearing.

[0009] In a preferred embodiment of this application, multiple mounting parts and a corresponding intermediate rotating cylinder are provided.

[0010] In a preferred embodiment of this application, the plurality of intermediate rotating cylinders are evenly arranged in the vertical and / or horizontal directions; in the horizontal direction, the axes of the plurality of intermediate rotating cylinders on the same horizontal plane are parallel; in the vertical direction, the axes of the plurality of intermediate rotating cylinders on the same vertical plane are parallel.

[0011] In a preferred embodiment of this application, multiple intermediate rotating cylinders on the same horizontal plane or multiple intermediate rotating cylinders on the same vertical plane are connected by a transmission component.

[0012] In a preferred embodiment of this application, the transmission component is a synchronous belt or a transmission chain, and the outer wall of the middle rotating cylinder is provided with a synchronous pulley corresponding to the synchronous belt or a toothed ring corresponding to the transmission chain.

[0013] In a preferred embodiment of this application, the terminal nozzle is detachably connected to the middle rotating cylinder.

[0014] In a preferred embodiment of this application, a yarn guide wheel is provided at the end of the terminal nozzle away from the middle rotating cylinder, and a yarn guide plate is provided between the yarn guide wheel and the middle rotating cylinder, and the yarn guide plate has a plurality of yarn holes for the yarn to pass through.

[0015] The front yarn separating guide is provided with a yarn separating grid at one end away from the middle rotating cylinder. The yarn separating grid has a yarn separating gap that allows the yarn to pass through, and the extending direction of the yarn separating gap is perpendicular to the axial direction of the yarn guide wheel.

[0016] In a preferred embodiment of this application, the mounting part is detachably connected to the outer frame, and the mounting part is deflectable relative to the outer frame.

[0017] Due to the adoption of the above-mentioned solution, the beneficial effects achieved by this application are as follows:

[0018] 1. During the left and right movement of the winding machine, the middle rotating drum in this application can rotate under the tension of the yarn, thereby causing the terminal yarn nozzle to rotate as well. This enables the three-axis winding machine to partially realize the function of the four-axis winding machine, thereby improving the fiber spreading effect, enhancing equipment performance and applicability, and ultimately helping to ensure and improve product quality.

[0019] 2. The outer skeleton, terminal yarn nozzle, front yarn separating guide and middle rotating drum in this application have simple structure, simple connection method, easy replacement of vulnerable parts, and low use cost and maintenance cost.

[0020] 3. In this application, the yarn contacts and engages with the yarn hole when moving left and right. This structure greatly shortens the engagement stroke between the yarn and the terminal nozzle, making it easier to drive the middle rotating drum to rotate. This results in a better follow-up effect of the terminal nozzle, which in turn helps to further improve the yarn spreading effect.

[0021] 4. By adopting the simple device in this application that converts a three-axis winding machine into a four-axis winding machine, existing traditional three-axis winding machines can be improved to achieve some of the functions of a four-axis winding machine. Compared to a four-axis winding machine, it eliminates the need for a separate servo motor to control the nozzle rotation angle, saving on equipment hardware costs and corresponding savings in software system development. Furthermore, by setting the mold rotation speed and platform movement speed, the yarn output speed can be controlled, allowing the rotating parts to rotate with the fiber movement, thus meeting the winding requirements of various angles for product winding.

[0032] To more clearly illustrate the overall concept of the present invention, a detailed description will be provided below with reference to the accompanying drawings and examples.

[0033] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0034] like Figure 1-3 As shown, this application discloses a simple device that can convert a three-axis winding machine into a four-axis winding machine. It mainly includes an outer frame 1, terminal yarn nozzles 4, a front yarn separating guide 5, and a middle rotating drum 2. The terminal yarn nozzles 4 and the front yarn separating guide 5 are arranged opposite each other at both ends of the middle rotating drum 2, which is rotatably connected to the outer frame 1. The middle rotating drum 2 has a yarn channel 23 inside, through which yarn can pass. The two ends of the yarn channel 23 are open and face the terminal yarn nozzles 4 and the front yarn separating guide 5, respectively. In actual use, the yarn first passes through the front yarn separating guide 5, then exits through the middle rotating drum 2, and finally reaches the mold surface through the terminal yarn nozzles 4.

[0035] During the winding process, the yarn moves left and right with the movement of the winding machine. Due to the tension in the yarn during winding, this left-right movement exerts pressure on the terminal nozzle 4 and the front yarn guide 5. The terminal nozzle 4 is directly connected to the intermediate rotating drum 2, which is connected to the outer frame 1 via a bearing 12. This allows the intermediate rotating drum 2 to rotate with the left-right movement of the winding machine, simultaneously rotating the terminal nozzle 4. This ensures that the fiber always exits perpendicular to the nozzle, improving the fiber spreading effect. This structure allows a three-axis winding machine to be initially converted into a four-axis winding machine and achieve some of the functions of a four-axis winding machine. It eliminates the need for a separate servo motor to control the nozzle rotation angle, saving on hardware costs and software development.

[0036] Furthermore, referring to Figure 1 As shown, the outer frame 1 is provided with a mounting part 11, and the middle rotating cylinder 2 is rotatably engaged with the mounting part 11. In one example, continue referring to... Figure 2 and Figure 3 As shown, the mounting part 11 is equipped with a bearing 12 corresponding to the intermediate rotating cylinder 2, and the intermediate rotating cylinder 2 is rotatably engaged with the mounting part 11 via the bearing 12. (Refer to...) Figure 3 As shown, the front yarn separating guide is fixed to the outer frame 1 by fastening screws.

[0037] In a preferred embodiment of this application, multiple mounting parts 11 and intermediate rotating cylinders 2 are correspondingly provided. The multiple intermediate rotating cylinders 2 are evenly arranged in the vertical and / or horizontal directions; in the horizontal direction, the axes of the multiple intermediate rotating cylinders 2 on the same horizontal plane are parallel; in the vertical direction, the axes of the multiple intermediate rotating cylinders 2 on the same vertical plane are parallel. Preferably, the multiple intermediate rotating cylinders 2 on the same horizontal plane or the multiple intermediate rotating cylinders 2 on the same vertical plane are connected by a transmission member 3. In one example, refer to... Figure 2 and Figure 3 As shown, the transmission component 3 is a synchronous belt 31, and the outer wall of the intermediate rotating cylinder 2 is provided with a synchronous pulley 21 corresponding to the synchronous belt 31. The synchronous pulley 21 is fixed to the outer wall of the intermediate rotating cylinder 2 by a flat key 22. In another example, the transmission component 3 is a transmission chain, and the outer wall of the intermediate rotating cylinder 2 is provided with a toothed ring corresponding to the transmission chain. Through the synchronous connection of the transmission component 3, multi-station synchronous operation can be realized, which improves production efficiency and ensures product consistency.

[0038] It should be noted that the arrangement of the mounting section 11 and the intermediate rotating cylinder 2 in this application is not limited to the examples mentioned above. The above are only some preferred embodiments of this application, and this application does not make any specific limitations.

[0039] As a preferred embodiment of this application, refer to Figure 2 As shown, the terminal nozzle 4 is detachably connected to the intermediate rotating cylinder 2. In one example, refer to... Figure 2 As shown, a mounting hole is provided on the side wall of the intermediate rotating cylinder 2 facing the terminal threaded nozzle 4, and a corresponding connecting hole 43 is provided on the side wall of the terminal threaded nozzle 4 facing the intermediate rotating cylinder 2. Bolts are used to connect and fix the intermediate rotating cylinder 2 and the terminal threaded nozzle 4 through the connecting hole 43 and the mounting hole. In the above solution, the connection structure between the terminal threaded nozzle 4 and the intermediate rotating cylinder 2 is simple, stable, and easy to disassemble, thus facilitating the replacement of the terminal threaded nozzle 4 according to different process requirements, which is beneficial to improving the functional expandability and applicability of the entire device.

[0040] It should also be noted that this application does not specifically limit the connection structure between the terminal screw nozzle 4 and the intermediate rotating cylinder 2; it can adopt the above-mentioned... Figure 2 The example in the text can also use other different connection methods and structures, such as pin connections, snap-fit ​​connections, etc.

[0041] In one example, continue to refer to Figure 2 and Figure 3As shown, a yarn guide wheel 41 is provided at the end of the terminal nozzle 4 away from the middle rotating drum 2. A yarn guide plate 42 is provided between the yarn guide wheel 41 and the middle rotating drum 2, and the yarn guide plate 42 has multiple yarn holes 421 for yarn to pass through. A yarn separating grid 51 is provided at the end of the front yarn separating guide away from the middle rotating drum 2. The yarn separating grid 51 has a yarn separating gap 511 for yarn to pass through, and the extending direction of the yarn separating gap 511 is perpendicular to the axial direction of the yarn guide wheel 41. With this structure, when the yarn moves left and right with the winding machine, the yarn can directly contact and cooperate with the yarn holes 421, thereby shortening the cooperation stroke between the yarn and the terminal nozzle 4 during left and right movement, making it easier to drive the middle rotating drum 2 to rotate, thus making the follow-up effect of the terminal nozzle 4 better, which is conducive to further improving the yarn spreading effect.

[0042] In a preferred embodiment of this application, the mounting part 11 is detachably connected to the outer frame 1, and the mounting part 11 can deflect relative to the outer frame 1. In this scheme, the detachable connection between the mounting part 11 and the outer frame 1 facilitates the inspection, maintenance, and replacement of the intermediate rotating drum 2. Furthermore, the deflection of the mounting part 11 relative to the outer frame 1 allows for adjustment of the yarn exit angle according to the size and specifications of the winding die and process requirements to achieve a better winding effect and improve product quality. In a preferred example, the outer frame 1 is connected to the machine bed of the three-axis winding machine. One of the outer frame 1 and the machine bed is provided with a mounting guide rail, and the other is provided with a connecting part adapted to the mounting guide rail. The outer frame 1 and the machine bed are connected and mounted on the mounting guide rail through the cooperation between the mounting guide rail and the connecting part. The mounting guide rail and the connecting part can be limited and fixed by limiting pins, limiting bolts, or other limiting components. This allows for a larger adjustable range of the yarn exit position and yarn exit angle, improving the adaptability of the equipment and further enhancing the winding effect and product quality. In another example, when the installation space on the machine bed of the three-axis winding machine is small or the space on the machine bed for the outer frame 1 to move is insufficient, the mounting part 11 can also move directly relative to the outer frame 1. In this case, a mounting guide rail is set on the outer frame 1, and the mounting part 11 is connected to the outer frame 1 through the mounting guide rail. The mounting part 11 can drive the middle rotating cylinder 2 and the terminal nozzle 4 to move relative to the outer frame along the mounting guide rail. This can also achieve the adjustment of the yarn exit position. Alternatively, the above two examples can be combined, with the movement of the outer frame 1 relative to the machine bed achieving coarse adjustment of the yarn exit position, and the movement of the mounting part 11 relative to the outer frame 1 achieving fine adjustment of the yarn exit position. It should be noted that the above examples are only some preferred examples of this application. The cooperation between the mounting part 11 and the outer frame 1, and the cooperation between the outer frame 1 and the machine bed are not limited to the above examples. Other different cooperation methods can also be used, and this application does not make specific limitations on them.

[0043] By employing the simple device described in this application that converts a three-axis winding machine into a four-axis winding machine, existing traditional three-axis winding machines can be improved to achieve some of the functions of a four-axis winding machine. Compared to a four-axis winding machine, it eliminates the need for a separate servo motor to control the nozzle rotation angle, saving on equipment hardware costs and corresponding savings in software system development. Furthermore, by setting the mold rotation speed and platform movement speed, the yarn output speed can be controlled, allowing the rotating parts to rotate with the fiber movement, thus meeting the winding requirements of various angles for product winding.
