[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figs. 1 to 3A high-speed braiding machine for easy yarn feeding includes a yarn feeding mechanism mounted on a high-speed braiding frame 1. The yarn feeding mechanism includes a yarn feeding spool 3, a mounting structure, a yarn binding structure, and a drive structure. A synchronization structure is provided between the yarn binding structure and the drive structure. The synchronization structure includes two synchronous pulleys 16 and a synchronous belt 17 connecting the two synchronous pulleys 16. The synchronization structure (including the two synchronous pulleys 16 and the synchronous belt 17) ensures synchronous movement between the yarn binding structure and the drive structure. This synchronization reduces errors and delays during the yarn feeding process, improving the overall operating efficiency and production speed of the braiding machine. The mounting structure includes a bottom fixing seat 4 with bearings mounted on the upper surface of the high-speed braiding frame 1 and a top fixing seat 5 positioned above the bottom fixing seat 4. An L-shaped mounting bracket 2 is welded to one outer surface of the high-speed braiding frame 1. The yarn feeding spool 3 is inserted and installed between the bottom fixing seat 4 and the top fixing seat 5. It should be noted that the top mounting base 5 is a telescopic and elastic structure. Both the bottom mounting base 4 and the top mounting base 5 contain positioning rods for fixing the pay-off drum 3. The top mounting base 5 is fixed to the lower surface of the mounting bracket 2. The telescopic and elastic design of the top mounting base 5 allows it to accommodate pay-off drums 3 of different lengths. A stable fixation is achieved by adjusting the telescopic length and elastic force of the top mounting base 5, eliminating the need to replace mounting bases of different sizes.

[0025] In this embodiment, a fixing frame 6 is fixed to the upper surface of the high-speed braiding frame 1. The wire binding structure includes a wire binding ring 7 slidably installed in the fixing frame 6, two mounting platforms 9 welded to the right side of the outer surface of the fixing frame 6 and distributed vertically, and a lifting screw 10 with bearings installed between the two mounting platforms 9 and penetrating the interior of the high-speed braiding frame 1. The lifting screw 10 has a threaded connection to a slider 11 fixed to the outer surface of the wire binding ring 7. The drive structure includes a dual-axis motor 13 fixed to the high-speed braiding frame 1, and a gear assembly installed between the dual-axis motor 13 and the bottom fixing seat 4. The gear assembly consists of transmission gears 14 and driven gears 15 of different sizes. The transmission gears 14 are fixed to the top output shaft of the dual-axis motor 13, and the driven gears 15 are fixed to the outer surface of the bottom fixing seat 4.

[0026] It should be noted that the two synchronous pulleys 16 are respectively fixed between the bottom end of the lifting screw 10 and the bottom output shaft of the dual-axis motor 13, and the two synchronous pulleys 16 are of different sizes. The different sizes of the two synchronous pulleys 16 ensure that the rotational speed of the lifting screw 10 matches the rotational speed of the dual-axis motor 13, so as to achieve precise adjustment of the height of the wire harness ring 7. A guide rod 12 for limiting the slider 11 is fixed between the two mounting platforms 9. The left and right sides of the fixing frame 6 are provided with sliding openings 8 that communicate with the outside. The slider 11 extends through the right sliding opening 8 into the interior of the fixing frame 6.

[0027] The mounting frame 6 is equipped with a blower structure 18 for use with the wire harness structure. The blower structure 18 includes a connecting arm 1801 slidably mounted on the mounting frame 6, a fan blade 1802 installed inside the connecting arm 1801, a connecting shaft 1803 fixed to one side of the fan blade 1802, and a linkage gear 1804 fixed to the other end of the connecting shaft 1803. A rack 1805 that meshes with the linkage gear 1804 is fixed to the outer surface of the high-speed braiding frame 1. The connecting arm 1801 is L-shaped, and the end of the connecting arm 1801 away from the fan blade 1802 extends into the left sliding opening 8 and is fixed to the left side of the wire harness ring 7. An installation groove is opened inside the connecting arm 1801, and the fan blade 1802 is fixed in the installation groove by the frame. The connecting shaft 1803 passes through the inside of the connecting arm 1801 and is connected to the bearing inside the connecting arm 1801. When the high-speed braiding frame 1 moves, the rack 1805 on its outer surface meshes with the linkage gear 1804 in the air blowing structure 18. This design converts the linear motion of the rack 1805 into the rotational motion of the linkage gear 1804, which in turn drives the connecting shaft 1803 and the fan blade 1802 to rotate. The airflow generated by the fan blade 1802 blows directly onto the wire near the cable tie ring 7, which can quickly remove the heat from the cable tie ring and its surrounding environment.

[0028] The working principle of the above embodiments is as follows:

[0029] First, the wire feeding drum 3 is installed between the bottom fixed seat 4 and the top fixed seat 5. The top fixed seat 5 has an elastic telescopic function, which can be finely adjusted according to the size of the wire feeding drum 3. The wire feeding drum 3 is fixed by a positioning rod. Then, the dual-axis motor 13 is started. The transmission gear 14 on its top output shaft meshes with the driven gear 15 on the outer surface of the bottom fixed seat 4, thereby driving the wire feeding drum 3 to rotate and feed the wire. At the same time, the bottom output shaft of the dual-axis motor 13 is connected to the lifting screw 10 through a synchronous structure, realizing the rotation of the lifting screw 10. The two synchronous wheels 16 are of different sizes to ensure that the rotation speed of the lifting screw 10 matches the rotation speed of the dual-axis motor 13, so as to achieve precise adjustment of the height of the wire loop 7.

[0030] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
