Description

Technical Field

[0001] This utility model relates to the technical field of carbon fiber winding equipment, and in particular to a dual-stroke winding mechanism. Background Technology

[0002] Carbon fiber, as a high-performance fiber, possesses a series of excellent properties such as high specific strength, high specific modulus, and good thermal stability, making it one of the most advanced reinforcing materials in recent years. The production of carbon fiber involves processes such as pre-oxidation, carbonization, surface treatment, sizing, drying, setting, and winding. Winding, as the final step in carbon fiber production, is characterized by a large number of individual machines, high winding requirements, and significant equipment investment. Currently, the commonly used carbon fiber cake widths on the market are 150mm and 250mm. Small tow carbon fiber generally uses a 150mm cake width, while large tow carbon fiber generally uses a 250mm cake width. However, conventional winding machines can only wind cakes of a fixed width. Changing the cake width requires adding a new batch of winding machines with different width specifications, which greatly increases equipment investment costs. Utility Model Content

[0043] like Figure 1 , 2 As shown in Figures 7 and 11, a double-stroke wire-laying mechanism includes a cylindrical outer shell 1, a wire-laying motor 2, and a double-stroke grooved roller 3. The wire-laying motor 2 is installed at one end of the cylindrical outer shell 1, and the double-stroke grooved roller 3 is located inside the cylindrical outer shell 1. The output end of the wire-laying motor 2 is connected to one end of the double-stroke grooved roller 3 via a connecting shaft, and the other end of the double-stroke grooved roller 3 is rotatably connected to the end of the cylindrical outer shell 1. A strip groove 4 is formed on the cylindrical outer shell 1 at the position corresponding to the position of the double-stroke grooved roller 3. A shuttle assembly is slidably installed on the double-stroke grooved roller 3. The shuttle assembly extends out of the cylindrical outer shell 1 from the position of the strip groove 4. A mounting base 5 is installed on the shuttle assembly, and a guide head fixing plate 6 is fixed on the mounting base 5. A guide head 7 is installed on the guide head fixing plate 6. When the motor starts, it drives the double-stroke grooved roller 3 to rotate inside the cylindrical outer shell 1 via the connecting shaft. This rotation of the double-stroke grooved roller 3 causes the shuttle assembly to reciprocate left and right, which in turn causes the guide head 7 to reciprocate on the guide wheel, thus achieving the wire laying function. By manually disassembling the shuttle 10 components, the shuttle 10 can be replaced into different grooves 9, achieving dual-groove switching. When the shuttle 10 slides in different grooves 9, the stroke of the guide head 7 will vary according to the stroke of the groove 9 (150mm or 250mm).

[0044] The dual-stroke grooved roller 3 includes a reciprocating grooved cylinder 8, on which two different strokes of sliding grooves 9 are machined.

[0045] like Figure 5As shown, the two types of slide grooves 9 with different strokes include a first slide groove and a second slide groove that intersect each other in an annular shape at 180 degrees. The strokes of the two slide grooves 9 are 150mm and 250mm respectively, the single lead of the two slide grooves 9 is 50mm, the stroke is an integer multiple of the single lead, and the difference in the number of spiral turns of the strokes of the two slide grooves 9 is an even number.

[0046] like Figure 3 , 4 As shown in Figures 9 and 10, the shuttle assembly includes a shuttle 10, a cylindrical guide sleeve 11, an upper slider 12, and a lower fixing block 13. The shuttle 10 matches the groove 9 of the double-stroke grooved roller 3 and slides within the groove 9. A guide post is connected to the shuttle 10 and is inserted into the cylindrical guide sleeve 11. The cylindrical guide sleeve 11, the upper slider 12, and the lower fixing block 13 are an integral structure, with the cylindrical guide sleeve 11 located below the lower fixing block 13. In the middle part, the cylindrical guide sleeve 11 and the lower fixing block 13 have through holes for the insertion of guide posts. The width of the lower fixing block 13 is smaller than the width of the upper slider 12. The top of the lower fixing block 13 protrudes upward. A rectangular notch 14 is provided in the middle of the upper slider 12. The protrusion at the top of the lower fixing block 13 is located in the rectangular notch 14. There is a gap between the top surfaces of both ends of the lower fixing block 13 and the lower side surface of the upper slider 12. The mounting seat 5 is fixed on the upper slider 12.

[0047] like Figure 8 As shown, a sliding sleeve 15 is fitted over the double-stroke grooved roller 3. A through hole is opened on the sliding sleeve 15. The shuttle 10 is located in the groove 9 of the double-stroke grooved roller 3 and inside the sliding sleeve 15. The guide post of the shuttle 10 passes through the through hole and extends into the cylindrical guide sleeve 11. The lower fixing block 13 is fixedly connected to the sliding sleeve 15. A steel strip 16 is fixed at the position of the strip groove 4 of the cylindrical outer shell 1. The steel strip 16 passes through the gap between the lower fixing block 13 and the upper slider 12 and the rectangular notch 14.

[0048] The shuttle assembly is the core component of the double-stroke winding mechanism. Its structural design ensures that the shuttle 10 can slide stably and accurately within the groove 9 of the double-stroke grooved roller 3, and achieves precise motion transmission through the guide post and guide sleeve.

[0049] Sliding shuttle 10: The sliding shuttle 10 matches the groove 9 of the double-stroke grooved roller 3 and can slide within the groove 9. The movement of the sliding shuttle 10 is driven by the rotation of the double-stroke grooved roller 3, and the sliding direction and stroke of the sliding shuttle 10 within the groove 9 are determined by the shape and size of the groove 9.

[0050] Guide post: The guide post is connected to the shuttle 10 and inserted into the cylindrical guide sleeve 11 to ensure that the shuttle 10 moves smoothly and without deviation.

[0051] Cylindrical guide sleeve 11: Cylindrical guide sleeve 11 provides a guiding channel for the guide post.

[0052] The upper slider 12 and the lower fixing block 13 are an integral structure. The width of the lower fixing block 13 is smaller than the width of the upper slider 12, and its top protrudes upward, embedding itself in the rectangular notch 14 of the upper slider 12. This structural design allows the shuttle assembly to remain stable during sliding, and the lower fixing block 13 is fixedly connected to the sliding sleeve 15, further enhancing the overall stability. In use, the upper slider 12 is located outside the cylindrical outer shell 1, and the lower fixing block 13 is located inside the cylindrical outer shell 1.

[0053] Mounting base 5: Mounting base 5 is fixed on the upper slider 12 and is used to install the guide head fixing plate 6 and the guide head 7, thereby transmitting the movement of the shuttle assembly to the guide head 7 to realize the wire laying function.

[0054] The sliding sleeve 15 is fitted over the double-stroke grooved roller 3, serving to protect and support it, while also providing an external fixing structure for the shuttle assembly.

[0055] Through hole: A through hole is provided on the sliding sleeve 15, through which the guide post of the shuttle 10 extends into the cylindrical guide sleeve 11. The through hole design allows the shuttle 10 to maintain its connection with the cylindrical guide sleeve 11 while sliding within the groove 9.

[0056] Fixed connection: The lower fixing block 13 is fixedly connected to the sliding sleeve 15. This connection method ensures that the shuttle assembly will not deviate or shake during the sliding process, thus improving the stability and reliability of the movement.

[0057] The steel strip 16 is fixed at the position of the strip groove 4 of the cylindrical outer shell 1, and passes through the gap between the lower fixing block 13 and the upper slider 12 and the rectangular notch 14. It has a dustproof effect without affecting the sliding of the shuttle assembly.

[0058] When the double-stroke grooved roller 3 rotates, the shuttle 10 slides in the groove 9, thereby driving the lower fixed block 13 and the upper slider 12 to move. The movement of the shuttle assembly is transmitted to the guide head 7 through the mounting seat 5, realizing the reciprocating motion of the guide head 7 and completing the wire laying function.

[0059] The design of this shuttle assembly, through precise structural matching and multiple fixing and guiding measures, ensures that the shuttle 10 can slide stably and accurately within the groove 9 of the double-stroke grooved roller 3. The auxiliary design of the sliding sleeve 15 further improves the stability and reliability of the motion, enabling the wire laying mechanism to complete the wire laying task efficiently and accurately.

[0060] By manually disassembling the shuttle 10 components, the shuttle 10 can be replaced with different slide grooves 9 to switch between the two slide grooves 9.

[0061] The guide head 7 includes 5-9 guide rollers.

[0062] The wrap angle of the guide wire head 7 is greater than 180 degrees.

[0063] The aforementioned ribbon motor 2 is a stepper motor or a servo motor.

[0064] like Figure 6 As shown, it also includes a back pressure roller, which is connected to the cylindrical outer shell 1 via a connecting bracket. The back pressure roller is arranged parallel to the cylindrical outer shell 1 and located below the guide roller. The function of the back pressure roller is to provide stable tension for the guide head 7, ensuring the uniformity and stability of the wire laying.

[0065] This utility model allows the shuttle 10 to slide independently in two grooves 9 by switching, forming two different wire laying strokes. The shuttle assembly is used to slide in the double-stroke grooved roller 3, dragging the external mechanism to move along the groove trajectory. The shuttle 10 and the cylindrical guide sleeve 11 slide in the sliding groove of the double-stroke grooved roller 3 according to its groove trajectory. The upper slider 12 is installed on the groove of the outer shell and makes parallel movement.

[0066] The back pressure roller 17 is used to apply pressure to the surface of the yarn bobbin, making the surface of the yarn bobbin flat. The guide head 7 is used for the introduction and exit of the yarn. It is connected to the sliding shuttle 10 and runs synchronously with the sliding shuttle 10. The yarn feeding motor 2 drives the double-stroke grooved roller 3 and controls the rotation of the double-stroke grooved roller 3 according to the program instructions, thereby driving the sliding shuttle 10 and the guide head 7 to slide. This utility model structure has a 150mm and 250mm double-stroke yarn feeding function, which can be used for winding two different yarn bobbin widths. The mechanism has the characteristics of dual-purpose machine and low investment cost.

[0067] The surface of the double-stroke grooved roller 3 is provided with a first and a second groove that intersect each other in an annular shape at 180 degrees. The strokes of the two grooves 9 are 150mm and 250mm, respectively, and the single lead of the groove 9 is 50mm. The stroke is an integer multiple of the single lead, and the difference in the number of spiral turns between the two strokes is an even number to ensure that they do not intersect at the ends. By manually disassembling the shuttle 10 component, the shuttle 10 and the cylindrical guide sleeve 11 can be switched between the two grooves 9 by replacing different grooves 9.

[0068] The slide shuttle 10 is a crescent-shaped slider mechanism. The crescent structure can slide in the double-stroke grooved roller 3 according to the trajectory of the slide groove 9. The reciprocating motion of the slide shuttle 10 component realizes the wire laying function.

[0069] The back pressure roller 17 is mounted on the outer casing. It applies pressure to the yarn and moves in tandem with the yarn roll diameter as the roll diameter increases, ensuring that the relative position of the yarn winding mechanism and the yarn outer diameter remains unchanged. The back pressure is 0.5-2 kg.

[0070] The guide head 7 is mounted on the shuttle 10 component and moves synchronously with the shuttle 10 component. The guide head 7 consists of 5-9 guide wheels to achieve the positioning and widening of the yarn.

[0071] The winding motor 2 is selected from stepper motors or servo motors. It is controlled by an external controller, enabling various winding control modes according to the winding process requirements, such as constant winding ratio, variable winding ratio, constant winding angle, and variable winding angle control. The preferred winding ratio is 7.0000-10.0000. Within this range, fine adjustments can achieve high-quality yarn cake forming.

[0072] The yarn passes through the guide head 7 at an angle greater than 180 degrees, and the friction force of the guide head 7 can overcome the movement of the yarn when it suddenly changes direction at the end face.

[0073] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the concept of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
