Description
Technical Field
[0001] This utility model relates to the field of metal fiber processing technology, specifically to a multi-strand fiber constant tension parallel stranding and rope-adding device. Background Technology
[0002] Metal fibers are typically made by winding dozens of metal wires, such as stainless steel, titanium, and copper, into a copper or other metal tube. Through multiple drawing processes, these fibers are reduced to micron-sized fibers of approximately 0.5 millimeters. Later, the metal tube becomes coated with metal fibers, which are then removed using processes like acid washing to obtain the final metal fibers. Depending on customer needs, multiple numbers of metal fibers may be required, necessitating the combination of two or more fibers together. Current technology using multi-strand winding suffers from poor mechanical tension control, especially during machine start-up and shutdown, which can cause sudden increases and decreases in tension. This can easily lead to the metal fibers being tangled or broken, severely impacting the quality and efficiency of metal fiber processing. Utility Model Content
[0003] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a multi-strand fiber constant tension parallel stranding and rope adding device, which can adjust the real-time tension during fiber conveying and avoid fiber breakage.

Detailed Implementation
[0021] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0022] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.
[0023] like Figures 1 to 4As shown in the figure, a specific embodiment of this utility model provides a multi-strand fiber constant tension stranding and rope-adding device, which can improve the efficiency and quality of metal fiber winding and stranding; specifically, it includes a wire feeding unit, a tension detection unit, and a stranding and winding unit arranged sequentially from upstream to downstream; the wire feeding unit includes a wire feeding frame 100, a detachable wire feeding reel 200 on the wire feeding frame 100, and a servo motor module 300 for driving the wire feeding reel 200 to rotate on the wire feeding frame 100; the tension detection unit includes a front tension wheel 400 and a rear tension wheel 500 arranged corresponding to each wire feeding frame 100, and a detection wheel 600 is provided between the front tension wheel 400 and the rear tension wheel 500, and a tension sensor is provided on the detection wheel 600; the stranding and winding unit includes a stranding wheel 700 located downstream of the rear tension wheel 500 for multiple strands of metal fibers to pass through, and a stranding and winding assembly is located downstream of the stranding wheel 700.
[0024] like Figures 1 to 4 As shown, with the above configuration, the strand winding equipment provided in this embodiment has a pay-off unit, a tension detection unit, and a strand winding unit. Pay-off is performed through the pay-off unit. In practical applications, a corresponding number of pay-off reels 200 are arranged according to the number of strands of metal fibers. Each type of metal fiber is wound onto a corresponding pay-off reel 200. During the pay-off process, the pay-off speed is controlled by the servo motor module 300. Each metal fiber filament can bypass the front tension wheel 400, detection wheel 600, and rear tension wheel 500 of the tension detection unit. The tension wheel structure ensures that each metal fiber has a certain tension. Therefore, during the pay-off transmission process, the tension sensor can detect the real-time tension data of each metal fiber. The servo motor module 300 controls the rotation speed to adjust the tension in real time, ensuring consistent tension between strands. Especially in cases of sudden increases or decreases in tension caused by the start-up and shutdown of the equipment, the sensor detects and the motor responds quickly to adjust, effectively preventing fiber breakage and loosening that could affect the quality of the finished metal fiber. After each metal fiber passes through the stranding wheel 700, they merge and are finally stranded through the strand winding assembly winding process, improving the efficiency and quality of automated processing.
[0025] In this embodiment, the tension sensor of the tension detection unit is combined with a high-precision digital transmitter, which features high sampling frequency and high data accuracy. In practical applications, the sampling frequency can reach up to 4800 times; the accuracy can reach 0.0001, realizing accurate detection of tension changes. Here, the tension sensor and digital transmitter adopt existing technology products. The specific models and specifications are selected as needed and will not be elaborated here.
[0026] As mentioned earlier, the metal fibers to be fed need to be wound onto the feed reel 200 and continuously fed by rotating it via a servo motor driver. To facilitate the assembly and disassembly of the feed reel 200, this embodiment has a drive shaft 800 on the feed frame 100. One end of the drive shaft 800 is connected to the servo motor module 300 via a coupling 900, and the other end is equipped with a fixing buckle 1000. The feed reel 200 can be detachably mounted on the drive shaft 800. A spring element 1100 is fitted onto the end of the drive shaft 800 away from the servo motor module 300. One end of the spring element 1100 abuts against the end of the feed reel 200, and the other end abuts against the fixing buckle 1000. In this way, the feed reel 200 can be mounted on the drive shaft 800 and fixed by the fixing buckle 1000. Since the drive shaft 800 is equipped with the spring element 1100, the feed reel 200 can be movably mounted, facilitating adjustment or replacement of the feed reel 200.
[0027] like Figure 4 As shown, the tension detection unit provided in this embodiment also includes a detection platform 1200. A tension frame 1300 is provided on the upper end of the detection platform 1200, on which the front tension wheel 400 and the rear tension wheel 500 are rotatably mounted. A detection frame 1400 is also provided on the detection platform 1200 between the front tension wheel 400 and the rear tension wheel 500, and the detection wheel 600 is rotatably mounted on the detection frame 1400. Thus, the tension wheel and the detection wheel 600 can be respectively mounted on the tension frame 1300 and the detection frame 1400 on the detection platform 1200. In practical applications, the structure of the detection wheel 600 and the tension wheel can be set according to the number of pay-off frames 100. To ensure stable delivery of the metal fibers on the pay-off reel 200 to the tension detection unit, this embodiment also provides a wiring wheel 1500 rotatably mounted on the detection platform 1200 upstream of the front tension wheel 400 and downstream of the rear tension wheel 500. The wiring wheel 1500 is provided with a wiring annular groove for the metal fibers on each pay-off reel 200 to pass through. In this way, the metal fibers can be stably conveyed by the wiring wheel 1500 before and after passing through the detection unit, which can prevent the metal fiber filaments from being disturbed during the conveying process.
[0028] like Figure 4 As shown, in this embodiment, a threading frame 1600 for multiple metal fibers to pass through is provided downstream of the threading wheel 700. In this way, the combined metal fibers can be wound and stranded after passing through the threading frame 1600.
[0029] like Figure 1As shown, the stranding and winding assembly provided in this embodiment includes multiple stranding wheel sets 1700 for stranding metal fibers to pass through. Downstream of the stranding wheel sets 1700, a take-up reel 1800 for collecting the stranded metal fibers is also provided. The combined metal fiber filaments are wound by rotating the stranding wheel sets 1700 to achieve stranding. The stranded metal fibers can finally be wound on the take-up reel 1800. In order to improve the structural strength of the stranded fibers, the stranding and winding assembly in this embodiment also includes a nylon reel 1900 located upstream of the take-up reel 1800 for winding nylon thread. A pay-off frame 100 is provided on the outside of the nylon reel 1900. The pay-off frame 100 is provided with a number of spaced guide wheels 2000. The nylon thread wound on the nylon reel 1900 passes through each guide wheel 2000 and then strands with multiple metal fibers by passing through the stranding wheel sets 1700. In this way, multiple fibers are combined with nylon yarn after being twisted together under constant tension, and the yarn is no longer loose. During the winding process, the winding length can be detected and calculated through structures and detectors such as encoders.
[0030] like Figure 1 As shown, in practical applications, the system also includes a frame 2100 for mounting the parallel winding assembly. A controller 2200 is mounted on the frame 2100. The controller 2200 is connected to the pay-off unit, tension detection unit, and parallel winding unit via signal connections. An operation display module 2300 is also connected to the controller 2200. Thus, the equipment can be automatically controlled via the controller 2200, and can be controlled using a PLC, etc. Technicians can use the operation display module 2300 for control operations, improving the automation level of the equipment.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
