Description

Technical Field

[0001] This utility model relates to the field of high-performance fiber preparation technology, and in particular to a drawing and positioning tool for manufacturing high-performance fibers. Background Technology

[0002] High-performance fibers refer to chemical fibers with special physicochemical structures, properties and uses, or special functions. They generally have extremely high tensile strength and Young's modulus, as well as other properties such as high temperature resistance, radiation resistance, flame resistance, high pressure resistance, acid resistance, alkali resistance, and oxidant corrosion resistance. They are widely used in aerospace, defense, transportation, industrial engineering, civil engineering, and even biomedicine and electronics industries.

[0003] Chinese utility model patent CN221940702U discloses a drawing and positioning fixture for manufacturing high-performance fibers, including a base plate, a fixed cylinder, a winding roller, a limiting component, and a transmission mechanism. A stirring roller is rotatably mounted inside the fixed cylinder, and a connecting rod is rotatably mounted inside the stirring roller. One end of the connecting rod is fitted with a toothed plate. This device uses a motor to drive the stirring roller to rotate and stir the high-performance fiber material. Combined with the transmission mechanism, connecting rod, and toothed plate, it achieves the reciprocating movement of the pressing plate during the rotation of the stirring roller. This facilitates simultaneous operation during stirring and extrusion, reduces power consumption, and improves extrusion efficiency. The extruded high-performance fiber material is limited by a limiting wheel. The arc-shaped groove on the outer side of the limiting wheel ensures more even force distribution on the circular high-performance fiber material. Combined with a buffer spring, it can be applied to high-performance fibers of different shapes and sizes.

[0004] Existing tooling does not provide precise tension control during fiber winding. Different high-performance fibers have very different tension requirements during drawing and winding. Existing tooling often uses a relatively simple tension adjustment method, which cannot be dynamically adjusted according to the real-time state of the fiber. When the tension is unstable, the fiber is prone to stretching deformation and breakage during winding, thus making it difficult to adjust the fiber tension. Utility Model Content

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] Example 1

[0032] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This is the first embodiment of the present invention. This embodiment provides a drawing and positioning fixture for manufacturing high-performance fibers, including a base 1. A screw extruder 2 and an adjusting mechanism 4 are fixedly connected to the upper surface of the base 1. A control panel 5 is fixedly connected to the outer surface of the screw extruder 2. A receiving mechanism 3 is slidably connected to the upper surface of the base 1. The receiving mechanism 3 includes a reciprocating block 313 slidably connected to the upper surface of the base 1. A limiting frame 305 is fixedly connected to the outer surface of the reciprocating block 313. A limiting roller 311 is rotatably connected to the inner wall of the limiting frame 305. Multiple sets of limiting grooves of different sizes are opened on the outer surface of the limiting roller 311. A reciprocating screw 312 is threadedly connected to the outer surface of the reciprocating block 313.

[0033] The specific material receiving mechanism 3 also includes a fixed plate 302 fixedly connected to the upper surface of the base 1. A servo motor 307 is fixedly connected to the outer surface of the fixed plate 302. The output shaft of the servo motor 307 passes through the outer surface of the fixed plate 302 and is fixedly connected to a second gear 309. A winding roller 314 is fixedly connected to the outer surface of the second gear 309. A winding drum 301 is slidably connected to the outer surface of the winding roller 314. A first gear 308 is meshed with the outer surface of the second gear 309. The outer surface of the first gear 308 is fixedly connected to one end of the reciprocating lead screw 312. Furthermore, a fixed block 306 is fixedly and rotatably connected to the other end of the reciprocating screw 312. The lower surface of the fixed block 306 is fixedly connected to the upper surface of the base 1. A limit rod 310 is fixedly connected to the outer surface of the fixed block 306. The outer surface of the limit rod 310 is slidably connected to the outer surface of the reciprocating block 313. A sliding groove 303 is provided on the upper surface of the base 1. A limit plate 304 is slidably connected to the outer surface of the sliding groove 303. A positioning bolt is threadedly connected to the outer surface of the limit plate 304. The lower end of the bolt is in contact with the outer surface of the sliding groove 303. The sliding groove 303 adopts a convex structure.

[0034] Furthermore, while the servo motor 307 drives the winding drum 301 to rotate, the gear transmission drives the reciprocating screw 312 to rotate, causing the reciprocating block 313 to reciprocate linearly along the limiting rod 310. This mechanism ensures that the fiber filaments can be evenly wound on the surface of the winding drum 301, avoiding problems such as uneven winding or accumulation. In addition, the design of the limiting plate 304 and the limiting rod 310 further ensures the stability of the winding drum 301 and the reciprocating block 313, and is applicable to winding drums 301 of different lengths, improving the versatility and operating efficiency of the equipment.

[0035] Example 2

[0036] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The adjustment mechanism 4 includes a fixed frame 405 fixedly connected to the upper surface of the base 1. An electric telescopic rod 402 is fixedly connected to the outer surface of the fixed frame 405. A sliding plate 403 is fixedly connected to the output end of the electric telescopic rod 402.

[0037] Specifically, the upper surface of the fixed frame 405 is fixedly connected with two sets of fixed rotating wheels 401, and the upper surface of the sliding plate 403 is fixedly connected with an adjusting rotating wheel 404.

[0038] Furthermore, the sliding plate 403 is moved by the electric telescopic rod 402, and the position of the adjusting wheel 404 changes accordingly, thereby adjusting the tension of the fiber filaments. This function ensures that the fiber maintains appropriate tension during winding, avoiding product quality issues caused by excessively loose or tight fibers, and improving the uniformity and consistency of fiber winding.

[0039] Working Principle: First, the raw material for producing high-performance fibers is added to the screw extruder 2. At this time, the control panel 5 on the outer surface of the screw extruder 2 allows for setting and adjusting the extruder's operating parameters, ensuring a stable extrusion process that meets production requirements. Starting the screw extruder 2 causes the raw material to be gradually extruded towards the fixed roller 401. As the raw material is extruded, fiber filaments are formed. Next, the fiber filaments are sequentially passed around the fixed roller 401 on the fixed frame 405, and then around the outer surface of the adjusting roller 404 and another set of fixed rollers 401, allowing the fiber filaments to enter the subsequent processing stage. Then, the fiber filaments pass through the limiting roller 311. Using multiple sets of limiting grooves of different sizes on the outer surface of the limiting roller 311, the appropriate groove is selected according to the fiber filament specifications, serving as a preliminary positioning and straightening tool for the fiber filaments. Finally, one end of the fiber filament is fixed to the outer surface of the winding drum 301, preparing it for winding and collection.

[0040] After the fiber threading is completed, the electric telescopic rod 402 is activated. The output end of the electric telescopic rod 402 drives the sliding plate 403 to slide on the upper surface of the base 1. Since the adjusting wheel 404 is mounted on the sliding plate 403, the movement of the sliding plate 403 changes the position of the adjusting wheel 404, thereby changing the path and angle of the fiber thread when it passes around the adjusting wheel 404, thus adjusting the tension of the fiber thread and ensuring that the fiber thread has a suitable tension during the subsequent winding process. This avoids affecting the fiber quality due to being too loose or too tight. After adjusting the fiber thread tension, the servo motor 307 is activated. The output shaft of the servo motor 307 drives the second gear 309 to rotate. The second gear 309 is fixedly connected to the winding roller 314, so the winding roller 314 will rotate accordingly, thereby driving the winding drum 301 to rotate and begin winding the fiber thread. At the same time, the second gear 309 meshes with the first gear 308, and the rotation of the second gear 309 will drive the rotation of the first gear 308. The first gear 308 is fixedly connected to one end of the reciprocating lead screw 312, so the rotation of the first gear 308 will cause the reciprocating lead screw 312 to rotate as well. The reciprocating lead screw 312 is threadedly connected to the reciprocating block 313. When the reciprocating lead screw 312 rotates, the reciprocating block 313 will slide along the outer surface of the limiting rod 310. Since the limiting rod 310 limits the reciprocating block 313 and prevents it from tilting, the reciprocating block 313 will perform reciprocating linear motion on the base 1. The limiting frame 305 and the limiting roller 311 are installed on the reciprocating block 313. This allows the fiber filaments to be evenly wound on the outer surface of the winding drum 301 as the reciprocating block 313 moves during the winding process, ensuring the flatness and uniformity of the winding. Depending on the length of the winding drum 301, the limiting plate 304 can be slid in the groove 303 on the upper surface of the base 1 to adjust it to a suitable position. Then, by tightening the positioning bolt, the lower end of the positioning bolt is tightly fitted with the outer surface of the groove 303, thereby limiting one end of the winding drum 301 and ensuring that winding drums 301 of different lengths can stably perform fiber winding work.
