Description

Technical Field

[0001] This utility model relates to the technical field of tension-adjustable wire drawing equipment, specifically to a tension-adjustable wire drawing equipment for producing composite material fiber webs. Background Technology

[0002] Composite fibers are the core reinforcing phase of composite materials. By combining them with matrices such as resins, they can significantly improve key properties of materials such as strength, stiffness, and corrosion resistance, making them a core component of lightweight and high-performance materials. Currently, composite materials are mainly formed by drawing precursors into continuous fibers using spinnerets or stencils. After production, the composite fibers are usually wound up for later use in weaving composite fiber webs. However, during the winding process, jamming in the winding equipment can easily lead to excessive stretching of the composite fibers, causing them to break and negatively impacting the production quality. Utility Model Content

[0003] The purpose of this invention is to solve the problem that composite fiber is easily stretched excessively during the winding process due to jamming of the winding equipment, which can easily lead to breakage of the composite fiber during winding. This invention provides a tension-adjustable drawing device for producing composite fiber webs.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution: A tension-adjustable drawing device for producing composite fiber webs includes a U-shaped plate. Multiple arc-shaped guide grooves are provided on both ends of the sidewalls of the U-shaped plate. A locking mechanism is fixedly installed on the upper side of the multiple arc-shaped guide grooves on the U-shaped plate. Two tensioning mechanisms are fixedly installed symmetrically inside the U-shaped plate, and a tension adjustment mechanism is fixedly installed on the U-shaped plate between the two tensioning mechanisms.

[0005] Preferably, the positioning mechanism includes an arc-shaped cover plate, one end of which is fixedly mounted with a connecting hinge, and one side of the connecting hinge is fixedly mounted on a U-shaped plate. The other end of the arc-shaped cover plate is fixedly mounted with a magnetic plate, and one end of the magnetic plate is magnetically attracted to the U-shaped plate.

[0006] Preferably, the tensioning mechanism includes an L-shaped plate, one side of which is fixedly mounted on a U-shaped plate, and an upper rotating shaft is rotatably mounted on the side wall of the L-shaped plate. A lower rotating shaft is rotatably mounted on the L-shaped plate below the upper rotating shaft, and rubber pressure rollers are fixedly sleeved on both the upper and lower rotating shafts.

[0007] Preferably, a guide notch is provided on the side wall of the L-shaped plate, a guide slider is slidably installed in the guide notch, one end of the lower rotating shaft is rotatably installed on the guide slider, a cylindrical spring telescopic rod is fixedly installed on the side wall of the guide notch, and one end of the cylindrical spring telescopic rod is fixedly installed on the end face of the guide slider.

[0008] Preferably, the tension adjustment mechanism includes a square columnar spring telescopic rod, one end of which is fixedly mounted on a U-shaped plate, and the other end of which is fixedly mounted on a base block, on which a traction arc plate is provided.

[0009] Preferably, an adjusting screw groove is provided on the side wall of the base block, a U-shaped frame is slidably sleeved on the outer side wall of the base block, an adjusting screw is rotatably installed on the side wall of the U-shaped frame, and one end of the adjusting screw is screwed into the adjusting screw groove. A locking ring is fixedly installed on the side wall of the U-shaped frame, and one side of the traction arc plate is fixedly installed on the locking ring.

[0010] The beneficial effects of this utility model are as follows: 1. In this utility model, by using components such as L-shaped plates, arc-shaped cover plates, and base blocks, when the composite material fibers need to be wound up after production, the drawn fibers are passed through the arc-shaped guide groove on the U-shaped plate, and then the arc-shaped cover plate is fastened. This allows the winding fibers to be limited by the two ends of the U-shaped plate and the arc-shaped cover plate. Then, the fibers are passed through two sets of rubber pressure rollers on the two L-shaped plates, which can maintain the tension of the fibers and ensure good fiber transmission efficiency. At the same time, the cylindrical spring telescopic rod 9 on the L-shaped plate can adjust the position of the two adjacent rubber pressure rollers, thereby accommodating various composite material fiber filaments of different lengths. The wound fiber filaments are passed through the traction arc-shaped plate. In this way, when equipment malfunctions and jams, the composite material fiber filaments can be released by pulling the square columnar spring telescopic rod upward, thus avoiding excessive pulling on the composite material fiber filaments and effectively reducing the probability of composite material fiber breakage.

[0017] like Figure 1-3As shown, a tension-adjustable drawing device for producing composite material fiber webs includes a U-shaped plate 1. Multiple arc-shaped guide grooves 2 are provided on both end sidewalls of the U-shaped plate 1. A locking mechanism is fixedly installed on the upper side of the multiple arc-shaped guide grooves 2 on the U-shaped plate 1. The locking mechanism includes an arc-shaped cover plate 4. A connecting hinge 3 is fixedly installed at one end of the arc-shaped cover plate 4, and one side of the connecting hinge 3 is fixedly installed on the U-shaped plate 1. A magnetic plate 5 is fixedly installed at the other end of the arc-shaped cover plate 4, and one end of the magnetic plate 5 is magnetically attracted to the U-shaped plate 1. The magnetic plate 5 allows the arc-shaped cover plate 4 to be easily attracted and fixed to the U-shaped plate 1. Furthermore, the arc-shaped cover plate 4, in conjunction with the arc-shaped guide grooves 2 on the U-shaped plate 1, forms a guiding space, thereby limiting the transmission of composite material fiber filaments.

[0018] Two tensioning mechanisms are symmetrically fixedly installed inside the U-shaped plate 1. The tensioning mechanism includes an L-shaped plate 7. One side of the L-shaped plate 7 is fixedly installed on the U-shaped plate 1, and an upper rotating shaft 11 is rotatably installed on the side wall of the L-shaped plate 7. A lower rotating shaft 13 is rotatably installed on the lower side of the L-shaped plate 7 below the upper rotating shaft 11. Rubber pressure rollers 12 are fixedly sleeved on both the upper rotating shaft 11 and the lower rotating shaft 13. By setting rubber pressure rollers 12 on both sides of the U-shaped plate 1, the composite material fibers on both sides can be tensioned at the same time, thereby maintaining the stable transmission of the composite material fibers and ensuring a good conveying and winding effect.

[0019] A guide notch 8 is provided on the side wall of the L-shaped plate 7. A guide slider 10 is slidably installed in the guide notch 8. One end of the lower rotating shaft 13 is rotatably installed on the guide slider 10. A cylindrical spring telescopic rod 9 is fixedly installed on the side wall of the guide notch 8, and one end of the cylindrical spring telescopic rod 9 is fixedly installed on the end face of the guide slider 10. The cylindrical spring telescopic rod 9 allows the guide slider 10 and the lower rotating shaft 13 to move along the guide notch 8, thereby allowing the lower rubber pressure roller 12 to move, thus adapting to composite material fibers of different sizes.

[0020] A tension adjustment mechanism 6 is fixedly installed on the U-shaped plate 1 between the two L-shaped plates 7. The tension adjustment mechanism 6 includes a square columnar spring telescopic rod 601. One end of the square columnar spring telescopic rod 601 is fixedly installed on the U-shaped plate 1, and the other end of the square columnar spring telescopic rod 601 is fixedly installed on a base block 602. A traction arc plate 607 is provided on the base block 602. The traction arc plate 607 is located between the two L-shaped plates 7, so that the composite material fiber filaments can reserve a certain amount of slack between the two L-shaped plates 7, which facilitates later release and avoids excessive pulling.

[0021] An adjusting screw groove 603 is provided on the side wall of the base block 602. A U-shaped frame 604 is slidably sleeved on the outer side wall of the base block 602. An adjusting screw 605 is rotatably installed on the side wall of the U-shaped frame 604, and one end of the adjusting screw 605 is screwed into the adjusting screw groove 603. A locking ring 606 is fixedly installed on the side wall of the U-shaped frame 604. One side of the traction arc plate 607 is fixedly installed on the locking ring 606. The adjusting screw 605 can drive the U-shaped frame 604 to raise and lower its height, thereby facilitating the raising and lowering of the traction arc plate 607 and the locking ring 606. The height difference between the traction arc plate 607 and the rubber pressure roller 12 can be used to adjust the reserved allowance, thus adapting to the adjustment of the reserved allowance for composite material fiber filaments of different sizes.

[0022] In summary: When the composite fiber needs to be wound up after production, the drawn fiber is first passed through the arc-shaped guide groove 2 on the U-shaped plate 1, and then the arc-shaped cover plate 4 is fastened. The magnetic plate 5 is used to drive the arc-shaped cover plate 4 to fix it. Thus, the U-shaped plate 1 and the arc-shaped cover plate 4 can limit the winding fiber. Then, the fiber is passed through the two sets of rubber pressure rollers 12 on the two L-shaped plates 7, so that the upper and lower rubber pressure rollers 12 can press the fiber. In this way, the rubber pressure rollers 12 at both ends can maintain the tension of the fiber. When the wound fiber filaments are of different sizes, the cylindrical spring telescopic rod 9 allows the guide slider 10 and the lower rotating shaft 13 to move along the guide notch 8, thereby allowing the lower rubber pressure roller 12 to move. This accommodates composite material fiber filaments of different sizes and ensures that the wound fiber filaments pass through the traction arc plate 607. The height difference between the traction arc plate 607 and the rubber pressure roller 12 allows for a certain amount of fiber filament allowance. In case of equipment malfunction or jamming, the composite material fiber filaments can be released by pulling the square columnar spring telescopic rod 601 upwards, thus preventing excessive stretching of the composite material fiber filaments. For fiber filaments of different thicknesses, the operator can use the adjusting screw 605 to raise or lower the U-shaped frame 604, which in turn allows for easy raising or lowering of the traction arc plate 607 and the locking ring 606. The height difference between the traction arc plate 607 and the rubber pressure roller 12 can then be used to adjust the allowance.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
