[0021] Reference Figure 1~Figure 5 The present embodiment proposes a braiding machine for low-voltage cable production, which is used to braid the core wire onto the braiding wire, including a frame 1; a main turntable 2 is rotatably arranged on the frame 1, and has a first wire hole 201 in the middle, and the first wire hole 201 is used to pass the core wire; there are a plurality of braiding wire shafts 3, which are arranged on the main turntable 2 for feeding the braiding wire and braiding it on the core wire; a wire end disk 4 is arranged on one side of the main turntable 2, and is located downstream of the main turntable 2 along the core wire conveying direction, and has a second wire hole 401 in the middle of the wire end disk 4; a plurality of clamps 5 are arranged in a circle on the wire end disk 4, and are used to clamp the wire ends of the braided wire.

[0022] In this embodiment, the frame 1 serves as the supporting structure of the entire device, ensuring the installation and operation stability of each component. The main turntable 2 can rotate stably on the frame 1. The first wire hole 201 is located in the middle of the main turntable 2. When the core wire passes through the hole, the rotation of the main turntable 2 drives the braiding spool 3 to braid around the core wire. The rotation of the main turntable 2 is driven by a motor to ensure the accuracy of the rotation speed and angle. A plurality of braiding spools 3 are evenly distributed on the main turntable 2. During the braiding process, the braiding spool 3 walks according to a preset trajectory, stably sends out the braiding wire and braids it on the core wire. The walking path and speed of the braiding spool 3 are carefully designed and debugged to ensure the uniformity and tightness of the braiding. The mobile drive of the braiding spool 3 is a prior art structure and will not be repeated here. The number of braiding spools 3 can be selected according to the braiding requirements to send out 12, 18 or 24 braided wires for braiding. The wire head disk 4 is arranged on one side of the main turntable 2 and is located downstream along the core wire conveying direction. The second wire hole 401 is used for the core wire to pass through. The position design of the thread end disk 4 enables the thread ends of the braided wire to be clamped and processed more conveniently.

[0023] In this embodiment, the chuck 5 is arranged circumferentially on the wire head plate 4. When it is necessary to start weaving or replace the braided wire, the chuck 5 can quickly and firmly clamp the wire end of the braided wire. The design of the chuck 5 adopts an elastic clamping structure, which can adapt to braided wires of different thicknesses and provide sufficient clamping force to prevent the wire end from loosening. Compared with the prior art in which the braided wires can only be tied together to start weaving, it is easier to achieve weaving and more efficient.

[0024] In this embodiment, the problem of low efficiency in installation and replacement of the braided wire ends is solved through the synergistic effect of the above-mentioned components. At the beginning of braiding, the clamp 5 can quickly clamp the wire ends and accurately position them on the core wire, thereby improving the efficiency of the initial braiding; when the braided wire on the braiding spool 3 is used up and needs to be replaced, the clamp 5 plays a role again, quickly clamping the new braided wire ends for replacement, reducing the operation time, improving the efficiency and stability of the entire braiding process, and ensuring the braiding quality of the low-voltage cable. The problem of difficult and inefficient installation and replacement of braided wire ends in the prior art is effectively solved, and the production efficiency and quality of the low-voltage cable are significantly improved.

[0025] Furthermore, the clamping head 5 is slidably disposed on the thread head disk 4 , and the sliding direction is along the radial direction of the thread head disk 4 .

[0026] In this embodiment, the chuck 5 is arranged to slide radially along the wire end disk 4. The design principle is to enable the chuck 5 to be flexibly adjusted according to the position and angle of the braided wire through sliding, so as to better clamp the wire end. In actual operation, when it is necessary to clamp the wire end of the braided wire, the chuck 5 can slide radially, close to the position of the wire end, so as to clamp the wire end more accurately. This sliding design increases the flexibility and adaptability of the operation of the chuck 5, so that it can adapt to wire ends in different positions and angles. The sliding chuck 5 improves the accuracy and stability of clamping the wire end. It reduces the situation where the wire end is difficult to clamp or not clamped firmly due to the fixed position of the chuck, thereby further improving the efficiency of installation and replacement of the braided wire end. The sliding setting of the chuck 5 optimizes the wire end processing capacity of the braiding machine, improves the working efficiency and reliability of the braiding machine, reduces the difficulty of operation and the error rate, and provides strong support for the efficient production of low-voltage cables.

[0027] Furthermore, a first elastic member 6 is included. One end of the first elastic member 6 acts on the clamp 5 , and the other end of the first elastic member 6 acts on the thread end disk 4 to provide a force to keep the clamp 5 away from the second thread hole 401 .

[0028] In this embodiment, one end of the first elastic member 6 acts on the chuck 5, and the other end acts on the thread end disk 4. The design principle is to use the elastic restoring force of the first elastic member 6 to provide the chuck 5 with a force to move away from the second thread hole 401. In actual work, when the chuck 5 needs to clamp the end of the braided thread, the elastic force of the first elastic member 6 is overcome to push the chuck 5 toward the second thread hole 401. After the thread end is clamped, the chuck 5 is released, and the elastic force of the first elastic member 6 automatically resets the chuck 5 away from the second thread hole 401 to prepare for the next clamping action.

[0029] In this embodiment, the presence of the first elastic member 6 makes the operation of the chuck 5 more convenient and efficient. The automatic reset function reduces the steps of manual operation and improves work efficiency. At the same time, the elastic force can make the clamping of the chuck 5 more stable, ensuring that the wire ends will not fall off easily, and avoiding the braided wire from contacting and entangled with the core wire being braided. In this embodiment, the cooperation between the first elastic member 6 and the chuck 5 further optimizes the wire end clamping operation of the braiding machine, improves the work efficiency and stability of the braiding machine, reduces the possibility of operational errors, and helps to improve the production quality and output of low-voltage cables.

[0030] Furthermore, the chuck 5 has an outer conical surface 500 and also includes a sliding push piece 7, which is slidably set on the frame 1, and the sliding direction is parallel to the axial direction of the core wire. The sliding push piece 7 has an inner conical surface 701, and the outer conical surface 500 abuts against the inner conical surface 701 and is configured to push the chuck 5 close to the second wire hole 401 after the sliding push piece 7 slides relative to the chuck 5.

[0031] In this embodiment, the chuck 5 has an outer conical surface 500, and the sliding push piece 7 is slidably arranged on the frame 1, and the sliding direction is parallel to the axial direction of the core wire, and the sliding push piece 7 has an inner conical surface 701, and the outer conical surface 500 abuts against the inner conical surface 701. The design principle is to utilize the axial sliding of the sliding push piece 7, and through the interaction between the inner conical surface 701 and the outer conical surface 500, the axial movement of the sliding push piece 7 is converted into the radial movement of the chuck 5. In actual operation, the sliding push piece 7 slides along the axial direction of the core wire. Due to the contact between the inner conical surface 701 and the outer conical surface 500, the sliding push piece 7 pushes the chuck 5 to overcome the elastic force of the first elastic member 6, so that the chuck 5 is close to the second wire hole 401. The purpose of this action is to change the angle of the braided wire relative to the core wire, so that the braided wire is close to the core wire, so that the braided wire can be automatically braided on the core wire without additional operation.

[0032] In this embodiment, this unique design can accurately adjust the relative position and angle between the braided wire and the core wire, ensuring that the braided wire is accurately and efficiently braided on the core wire. It avoids complicated additional operations and improves the automation and efficiency of the braiding process. The matching structure of the sliding push piece 7 and the clamp 5 cleverly solves the initial braiding problem of the braided wire and the core wire, greatly improves the working efficiency and braiding quality of the braiding machine, reduces the difficulty of operation and the need for manual intervention, and provides a strong guarantee for the stable production of low-voltage cables.

[0033] In this embodiment, a second elastic member 8 is provided, one end of which acts on the sliding push member 7 and the other end of which acts on the frame 1. The design principle is to use the elastic restoring force of the second elastic member 8 to provide the sliding push member 7 with a force to approach the chuck 5. In actual operation, when the sliding push member 7 needs to be adjusted or reset away from the chuck 5, the elastic force of the second elastic member 8 is overcome to move it. When the adjustment is completed or the sliding push member 7 does not need to be away from the chuck 5, the elastic force of the second elastic member 8 will automatically make the sliding push member 7 approach the chuck 5 and keep it in a suitable position, so that the chuck 5 can be pushed timely and effectively to change the angle of the braided line when needed.

[0034] In this embodiment, the presence of the second elastic member 8 enables the position of the sliding push member 7 to be automatically maintained and restored, thereby improving the stability and reliability of the device. At the same time, the elastic force can ensure the tightness of contact and the timeliness of action between the sliding push member 7 and the clamp 5, thereby more effectively achieving accurate braiding of the braided wire and the core wire. The cooperation of the second elastic member 8 and the sliding push member 7 further optimizes the operating stability and braiding efficiency of the braiding machine, reduces the possibility of operating errors, and helps to improve the production quality and output of low-voltage cables.

[0035] Furthermore, the thread end disk 4 is slidably arranged on the frame 1, and the sliding direction is parallel to the axial direction of the core wire. It also includes a third elastic member, one end of the third elastic member acts on the frame 1, and the other end acts on the thread end disk 4, providing a force for the thread end disk 4 to approach the main turntable 2, so as to make the thread end disk 4 move away from the sliding push piece 7 and approach the main turntable 2 after the thread end of the braided wire is detached from the chuck 5.

[0036] In this embodiment, the thread end disk 4 is slidably arranged on the frame 1, and the sliding direction is parallel to the axial direction of the core wire. One end of the third elastic member acts on the frame 1, and the other end acts on the thread end disk 4. The design principle is to provide a force for the thread end disk 4 to approach the main turntable 2 through the elastic restoring force of the third elastic member.

[0037] In actual work, when the end of the braided wire is clamped by the clamp 5 and the initial braiding or angle adjustment is completed, the end of the wire is separated from the clamp 5. At this time, the elastic force of the third elastic member causes the end disk 4 to automatically move away from the sliding push member 7 and close to the main turntable 2. The technical effect of this design is that the end disk 4 can be adjusted to a suitable position in time to avoid interference with the subsequent braiding process. At the same time, the automatic resetting of the elastic member improves the consistency and efficiency of the operation, and reduces the time and labor intensity of manual adjustment.

[0038] In this embodiment, the cooperation between the third elastic member and the thread end disk 4 realizes the automatic adjustment of the position of the thread end disk 4, optimizes the workflow of the braiding machine, improves production efficiency and braiding quality, reduces the complexity and error rate of operation, and provides strong support for the stable and efficient production of low-voltage cables.

[0039] Furthermore, the frame 1 has a guide groove 101, the sliding push piece 7 has a guide portion 702, the guide portion 702 is slidably arranged in the guide groove 101, the guide groove 101 has a front limit portion 102 and a rear limit portion 103, and the front limit portion 102 and the rear limit portion 103 are respectively located on both sides of the guide portion 702.

[0040] In this embodiment, a guide groove 101 is provided on the frame 1, and the sliding push piece 7 has a guide portion 702 matched therewith, and the guide portion 702 is slidably arranged in the guide groove 101. The design principle is to provide accurate guidance and stable support for the sliding of the sliding push piece 7 through the cooperation between the guide groove 101 and the guide portion 702. The guide groove 101 has a front limit portion 102 and a rear limit portion 103, which are respectively located on both sides of the guide portion 702. In actual work, the front limit portion 102 limits the extreme position of the sliding push piece 7 sliding forward, preventing the sliding push piece 7 from excessively moving forward and affecting normal work; the rear limit portion 103 limits the extreme position of the sliding push piece 7 sliding backward, ensuring that the sliding push piece 7 will not retract excessively under the action of the second elastic member 8.

[0041] In this embodiment, the sliding stroke of the sliding pusher 7 can be accurately controlled to ensure that it moves stably within a specified range. This avoids problems such as inaccurate braiding line position and reduced braiding quality caused by excessive or insufficient sliding of the sliding pusher 7. The cooperation of the guide groove 101 with the guide portion 702 and the front limit portion 102 and the rear limit portion 103 improves the accuracy and stability of the sliding of the sliding pusher 7, thereby optimizing the performance of the braiding machine and improving the production quality and efficiency of the low-voltage cable.

[0042] Furthermore, the inner conical surface 701 is located on the side of the thread end disk 4 away from the main turntable 2 , and the cross-sectional diameter of the inner conical surface 701 gradually decreases from close to the main turntable 2 to away from the main turntable 2 .

[0043] In this embodiment, the inner conical surface 701 is located on the side of the wire end disk 4 away from the main turntable 2, and the cross-sectional diameter of the inner conical surface 701 gradually decreases from close to the main turntable 2 to far away from the main turntable 2. The design principle is that the moving direction of the sliding push piece 7 is limited by this structure with gradually decreasing cross-sectional diameter. When the sliding push piece 7 moves along the axial direction of the core wire, the direction and range of its movement can be clearly defined due to the change in the diameter of the inner conical surface 701. The special design of the inner conical surface 701 further optimizes the operating stability and braiding effect of the braiding machine by limiting the moving direction of the sliding push piece 7, providing strong support for the efficient and high-quality production of low-voltage cables.

[0044] Furthermore, the chuck 5 includes a first clamping portion 501, which is slidably disposed on the thread end disk 4, and the sliding direction is along the radial direction of the thread end disk 4; the second clamping portion 502 is slidably disposed on the first clamping portion 501, and a clamping space 503 is formed between the second clamping portion 502 and the first clamping portion 501, and the clamping space 503 is used to clamp the thread end of the braided line.

[0045] In this embodiment, the clamp 5 includes a first clamp 501 and a second clamp 502. The first clamp 501 is slidably disposed on the thread head disk 4, and the sliding direction is along the radial direction of the thread head disk 4. The design principle is to clamp the braided thread end by sliding in the radial direction. The second clamp 502 is slidably disposed on the first clamp 501, and a clamping space 503 is formed between the second clamp 502 and the first clamp 501. The design principle is that the sliding of the second clamp 502 relative to the first clamp 501 can change the size of the clamping space 503, thereby achieving the clamping and loosening of the braided thread end.

[0046] In actual work, when it is necessary to clamp the end of the braided wire, the first clamp 501 slides to a suitable radial position, and the second clamp 502 slides relatively to reduce the clamping space 503 and clamp the end of the wire tightly. When it is necessary to loosen the end of the wire, the second clamp 502 slides in the opposite direction to increase the clamping space 503. In this embodiment, the clamp structure can more flexibly and accurately control the clamping operation of the end of the braided wire. The stability and reliability of the clamping are improved to ensure that the end of the wire will not loosen or fall off during the braiding process.

[0047] Furthermore, the clamp 5 also includes a fourth elastic member 504 , one end of which acts on the second clamp 502 , and the other end of which acts on the first clamp 501 , providing a force for the second clamp 502 to approach the first clamp 501 to clamp the end of the braided wire.

[0048] In this embodiment, the chuck 5 also includes a fourth elastic member 504, one end of which acts on the second clamp 502 and the other end of which acts on the first clamp 501. The design principle is to use the elastic restoring force of the fourth elastic member 504 to provide the second clamp 502 with a force to clamp the braided wire end close to the first clamp 501. In actual operation, when it is necessary to clamp the braided wire end, the external force overcomes the elastic force of the fourth elastic member 504, so that the second clamp 502 is away from the first clamp 501, and the clamping space 503 is expanded to facilitate the insertion of the wire end. After the wire end is inserted, the external force disappears, and the elastic force of the fourth elastic member 504 causes the second clamp 502 to quickly approach the first clamp 501 to clamp the wire end. The presence of the fourth elastic member 504 enables the chuck 5 to automatically clamp the wire end, thereby improving the timeliness and stability of the clamping operation. The structural cooperation between the fourth elastic member 504 and the clamp 5 further optimizes the clamping mechanism of the braided wire ends, improves the working efficiency and reliability of the braiding machine, ensures the smooth progress of the braiding process, and helps to improve the production quality and output of low-voltage cables.
