Description

Technical Field

[0001] This utility model relates to a wire stranding and braiding device, specifically an integrated device for stranding and braiding multiple pairs of ultra-fine wires. Background Technology

[0002] In existing technologies, the stranding and braiding processes of multiple pairs of composite ultra-fine medical filaments are usually separate, requiring multiple pairs to be stranded individually and then assembled before braiding. This leads to low production efficiency and increases the risk of material damage. For example, common stranding equipment (such as the patent application number CN119541955A) has a complex structure, high maintenance costs, and difficulty in ensuring the consistency of multiple stranded filaments. Separate braiding equipment (such as the patent application number CN116453777A) is prone to causing filament loosening and deformation when receiving multiple pairs of parallel, individually stranded filaments, affecting the quality of the final product. Therefore, there is an urgent need for a new type of equipment that can effectively integrate these two processes, simplifying the production process, reducing the transfer of semi-finished products, reducing the uncontrollability and damage to the filaments during manufacturing, improving product quality, reducing production losses, increasing production efficiency, and ensuring the integrity of the filaments. This integrated solution is crucial for improving the performance and reliability of medical devices. Utility Model Content

The cable bundling platform 23 is provided with two wire-passing holes 231 and is fixed to the support column 22, which is fixed to the upper support 12. The multiple cable reels 21 are divided into two groups, which are distributed at both ends of the cable bundling platform 23. The two groups of cable reels 21 pass through the two wire-passing holes 231 respectively. The lower extension seat 31 and the first fixed pulley 32 are both fixed to the upper support 12. The upper and lower extension seats 31 are provided with threading holes 311. The guide wheel 41 and multiple braiding cylinders 43 are rotatably connected to the upper support 12.

A support block 44 is fixed on the cable tube 42 and fixed on the upper support 12. The wire is conveyed from the first fixed pulley 32 to the guide wheel 41, and then passes through the through hole 121 and out of the cable tube 42. The traction mechanism 5 includes a mounting base 52. Two traction tracks 53 are installed on the mounting base 52. Both traction tracks 53 are horizontally arranged. The traction tracks 53 adopt an upper and lower pressing tension control scheme. The wire to be woven passes between the two traction tracks 53.

The twisting pitch error between each pair of wires is less than 5%. In this embodiment, the PLC controller 81 is model S7-200, and the sensor 82 is an acceleration sensor or a magnetic sensor. If an acceleration sensor is used, its model is MPU6050; if a magnetic sensor is used, its model is KY-003.

[0027] Please refer to the following: Figures 1 to 5 In the operation of this utility model, multiple pairs of wires can be loaded at once using multiple winding drums 21. Each pair of wires can be twisted simultaneously and individually. The twisting direction of each pair of wires can be set differently; they can all be selected in a clockwise or counterclockwise direction, or some can be twisted in a clockwise direction and some in a counterclockwise direction. In addition, the twisting and unwinding device 2 can also be selected to untwist or not untwist. The wires are output from the multiple winding drums 21, pass through the threading hole 231, and then pass through the threading eye 311. They are then transferred to the guide wheel 41 by the first fixed pulley 32 and then through the guide wheel 41. After passing through the wire tube 42 through hole 121, the wire is shaped by two traction tracks 53, then passes through the wire storage rack 61 and the second fixed pulley 62 and is wound up in the take-up shaft 72. During this process, the rotation of the wire feeding device is monitored in real time by sensor 82. When either the stranding wire feeding device 2 or the braiding wire feeding device 4 has insufficient material or a broken wire, and the wire feeding device stops rotating, an electrical signal is immediately transmitted to the PLC controller 81 to stop the equipment from running. The rotation speed of the stranding part is dynamically adjusted according to the running speed of the braiding part to achieve synchronous acceleration and deceleration.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
