Description

Technical Field

[0001] This utility model relates to the field of glass fiber processing technology, specifically to a glass fiber stranding device. Background Technology

[0002] The glass fiber stranding device is the core equipment in glass fiber production. Its core function is to bundle multiple monofilament fibers into composite fiber bundles to improve the overall mechanical properties, uniformity and processability of glass fibers.

[0003] For example, Chinese utility model patent with publication number "CN220334363U" discloses a glass fiber stranding device, including a substrate, a support frame fixedly connected to the substrate, a main shaft rotatably connected to the support frame, a fixing frame fixedly connected to the main shaft, a secondary shaft rotatably connected to the fixing frame, a transmission assembly between the main shaft and the secondary shaft, a feed roller fixedly connected to the secondary shaft, a sealing plate movably connected to the feed roller, a locking pin threadedly connected to the feed roller, a feed reel fixedly connected to the end of the main shaft, a gathering ring fixedly connected to the substrate, a take-up roller rotatably connected to the substrate, a baffle threadedly connected to the take-up roller, a lead screw rotatably connected to the substrate, and a guide block threadedly connected to the lead screw. The advantage of this utility model is that the guide block circulates back and forth on the lead screw, allowing the glass fibers to be neatly and orderly wound onto the take-up roller, avoiding the problem of misaligned glass fibers causing confusion on the take-up roller.

[0004] However, the aforementioned stranding device lacks a tension control device, making it impossible to adjust the tension of the glass fiber during the stranding process, which makes the glass fiber prone to breakage. Furthermore, after the glass fiber passes through the feed reel, it directly enters the cohesive ring, causing the glass fiber to bend sharply at the feed reel, resulting in a sudden increase in glass fiber stress and making it extremely easy to break.

The wire gathering ring 13 is disposed on the first support plate 3. The rotating column 6 is rotatably disposed on the second support plate 4 and the third support plate 5. The first turntable 7 is disposed at the end of the rotating column 6 and located between the first support plate 3 and the second support plate 4. The first turntable 7 is equipped with... The first threading hole 16, the second turntable 8 and the third turntable 9 are sequentially sleeved on the rotating column 6 from left to right and are located between the second support plate 4 and the third support plate 5. The second turntable 8 is provided with a support column 18, the support ring 10 is provided on the support column 18, the wire feeding assembly 11 is provided between the second turntable 8 and the third turntable 9, and the tension adjustment assembly 12 is provided on the first turntable 7. The second support plate 4 is provided with a wire passage groove 25. The base 1 is provided with a motor 26, the output shaft of the motor 26 is sleeved with a first pulley 27, the rotating column 6 is sleeved with a second pulley 28, and the first pulley 27 and the second pulley 28 are sleeved with a transmission belt 29.

[0025] The wire feeding assembly 11 is provided with several sets, and the number of tension adjustment assemblies 12 is equal to the number of wire feeding assemblies 11 and corresponds one-to-one. The rotating column 6 is also provided with several sets of guide wheels 14 that correspond one-to-one with the wire feeding assembly 11. The rotating column 6 is provided with a fixed seat 15, and the guide wheels 14 are rotatably mounted on the fixed seat 15 through a wheel axle.

[0026] The tension adjustment assembly 12 includes a spring 22, a tension adjustment wheel 23, and a rotating arm 24. A support 17 is provided on the first turntable 7, and the rotating arm 24 is hinged on the support 17. The tension adjustment wheel 23 is rotatably mounted on the rotating arm 24 via a wheel axle. The two ends of the spring 22 are respectively mounted on the rotating arm 24 and the first turntable 7.

[0027] The wire feeding assembly 11 includes a rectangular mounting frame 19 and a wire feeding roller 20. Two sets of rotating shafts 21 are symmetrically arranged on the rectangular mounting frame 19.

[0028] In practical use, several sets of feed rollers 20 feed multiple sets of glass fibers that need to be stranded together. The glass fibers pass through the second threading hole 30, then around the support ring 10, and then pass through the bottom of the guide wheel 14, the first threading hole 16 and the top of the tension adjusting wheel 23 in sequence. Finally, they pass out through the gathering ring 13. The composite fiber bundle that passes out through the gathering ring 13 is wound up by an external winding device (not shown in the figure).

The second pulley 28 drives the rotating column 6 to rotate, which in turn drives the first turntable 7, the second turntable 8, and the third turntable 9 to strand the glass fibers. During the stranding process, the tension can be adjusted by the tension adjustment component 12, and the support ring 10 and the guide wheel 14 can prevent excessive bending stress on the glass fibers, thereby effectively preventing the glass fibers from breaking.

[0030] In summary, this solution includes a tension adjustment component 12, which facilitates the adjustment of the tension of the glass fiber during stranding to prevent breakage. The solution also includes a support ring 10 and a guide wheel 14. The support ring 10 provides a support point with a constant radius of curvature for the glass fiber, and the support ring 10 and guide wheel 14 prevent sharp bends in the glass fiber, reducing bending stress and preventing breakage.
