Description

Technical Field

[0001] This utility model relates to the field of cable production technology, specifically to an automated braiding machine for cable braided layers. Background Technology

[0002] Cable braiding is a common cable protection structure. It involves tightly weaving materials such as metal wires, nylon threads, or polyester threads onto the outside of the cable through a braiding process to enhance the cable's physical protection capabilities, such as abrasion resistance, cut resistance, and partial electromagnetic shielding. Cable braiding machines are specialized mechanical equipment used to manufacture cable braids (mainly braiding sheaths and shielding layers). These machines are primarily used to produce various types of cables, such as power cables and communication cables, to enhance the cable's mechanical protection and electromagnetic shielding performance.

[0003] Chinese Patent Publication No. (CN220155274U) discloses a high-speed braiding machine for cables, including a base, a feeding roller installed at the top of the base, a support frame installed at the top of the base and connected to gear a, a wire tube installed on the support frame and connected to a rotating disk, a plurality of spindles arranged on the rotating disk, a sorting cylinder a arranged on one side of the wire tube and a sorting cylinder b arranged on one side of the sorting cylinder a, a cleaning cylinder arranged between the sorting cylinder a and the sorting cylinder b and connected to gear b, and a take-up roller installed at the top of the base;

Firstly, the friction layer is connected to the lower and upper cylinders via Velcro, and the upper cylinder can be opened by rotating around a pivot using a knob. This allows for direct replacement of the friction layer without the need for complete disassembly of the cylinder, simplifying the operation and significantly reducing replacement time, effectively minimizing equipment downtime and improving continuous operation efficiency. Secondly, the locking and unlocking of the upper and lower cylinders is achieved through an L-shaped rotating shaft, locking block, and compression spring. Operation requires only pressing or rotating the knob to open and close. The knob surface features an annular concave anti-slip texture, increasing hand friction, facilitating force application, and reducing operational intensity. Finally, the spindle is equipped with double bearing positioning to reduce radial sway. Additionally, a rubber shock-absorbing pad is fitted at the connection between the spindle and the bearing, effectively absorbing vibrations generated during high-speed rotation of the rotating disc, reducing spindle sway, ensuring stable wire braiding trajectory, and improving the uniformity of the braided layer.

[0030] Please see Figure 1-5 As shown, an automated braiding machine for cable braiding includes a base plate 1;

[0031] Two support plates 2 are symmetrically fixedly connected to the top of the base plate 1. The top of the two support plates 2 is fixedly connected to the lower cylinder 201. The top of the lower cylinder 201 is rotatably connected to the upper cylinder 202 through a pin. The interiors of the lower cylinder 201 and the upper cylinder 202 are symmetrically fixedly connected to two Velcro straps 203. The surfaces of the two Velcro straps 203 are bonded with a friction layer 204.

[0032] The friction layer 204 is a composite structure, including a base layer and a wear-resistant layer; the base layer is nylon mesh, which is connected to the lower cylinder 201 and the upper cylinder 202 by Velcro 203; the wear-resistant layer is a silicon carbide fiber layer, which is fixedly attached to the inside of the base layer.

[0033] Connecting block a205 and connecting block b206 are fixedly connected to the surfaces of the lower cylinder 201 and the upper cylinder 202, respectively.

[0034] The inner cavity of the connecting block a205 is rotatably connected to a rotating shaft 207. One end of the rotating shaft 207 is fixedly connected to a knob 208, and the other end is fixedly connected to a locking block 209. A compression spring 2010 is sleeved between the knob 208 and the connecting block a205.

[0035] The connecting block b206 has a locking groove 2011 inside, and a guide groove 2012 adapted to the locking block 209 is provided on the top of the connecting block b206. The guide groove 2012 is connected to the locking groove 2011.

[0036] A connecting plate 3 is fixedly connected to the middle of the top of the base plate 1. A wire tube 301 is embedded in the inner cavity of the connecting plate 3. A rotating disk 302 is embedded on the surface of the wire tube 301. Multiple bearings 303 are embedded in the inner cavities at both ends of the rotating disk 302 in a ring array. A spindle 304 is inserted through the inner cavity of two bearings 303.

[0037] The surface of the rotating disk 302 is fixedly connected with multiple gear teeth 4 in a ring array. One end of the connecting plate 3 is fixedly connected to a drive motor a401. One end of the output shaft of the drive motor a401 is fixedly connected to a gear 402, which meshes with the gear teeth 4.

[0038] Two support frames a5 and two support frames b501 are fixedly connected to the top two sides of the base plate 1 respectively. The inner cavity of the two support frames a5 is rotatably connected to the feeding roller 502, and the inner cavity of the two support frames b501 is rotatably connected to the winding roller 503.

[0039] A servo motor b6 is fixedly connected to one end of both the feeding roller 502 and the winding roller 503. The housing of the servo motor b6 is fixedly connected to the surface of the support frame a5 and the support frame b501, respectively.

[0040] A shock-absorbing pad is fitted at the connection between the surface of the spindle 304 and the bearing 303. The shock-absorbing pad is a rubber shock-absorbing pad.

[0041] The surface of the knob 208 is provided with anti-slip texture, which is a concave structure in a ring array;

[0042] The rotating shaft 207 and the locking block 209 are in an L-shaped structure, and the inner wall of the friction layer 204 is in an arc shape to fit the outer surface of the cable.

[0043] When the equipment is running, the upper cylinder 202 and the lower cylinder 201 are first unlocked by operating knob 208: First, rotate knob 208 to drive the rotating shaft 207 and locking block 209 to rotate synchronously. At this time, the compression spring 2010 is in a compressed state. When the position of locking block 209 corresponds to the position of guide groove 2012, compression spring 2010 extends, driving the rotating shaft 207, knob 208 and locking block 209 to move upward, so that locking block 209 disengages from locking groove 201 along guide groove 2012. The inner cavity of 1 is opened by rotating the upper cylinder 202 around the pin axis, allowing the cable to be braided to be led out from the feeding roller 502, passing through the conductor tube 301, the center of the rotating disk 302, and the channel between the lower cylinder 201 and the upper cylinder 202 in sequence, and finally fixed on the take-up roller 503; then the knob 208 is operated in the opposite direction to make the locking block 209 re-engage in the locking groove 2011, and the upper cylinder 202 and the lower cylinder 201 are closed, and the internal friction layer 204 is in contact with the outer surface of the cable due to the arc structure of the inner wall;

[0044] After the equipment is started, servo motor b6 drives the feeding roller 502 and the winding roller 503 to rotate, and stabilizes the cable conveying tension by synchronously controlling the speed. At the same time, drive motor a401 drives gear 402 to rotate. Gear 402 meshes with the gear teeth 4 on the surface of rotating disk 302, thereby driving rotating disk 302 to rotate around conductor tube 301. When rotating disk 302 rotates, spindles 304 mounted on both ends of it through bearings 303 move synchronously with rotating disk 302. The metal wires on spindles 304 are braided around the cable to form a cable braided layer. The rubber shock-absorbing pads at the connection between spindle 304 and bearing 303 can reduce vibration during high-speed rotation and ensure braiding accuracy.

[0045] The braided cable continues to be conveyed between the lower cylinder 201 and the upper cylinder 202. The friction layer 204 in the closed state contacts the surface of the cable and cleans the burrs and debris on the surface of the braided layer during the movement of the cable. The friction layer 204 connected by Velcro 203 can be easily replaced according to the wear condition. Finally, the cleaned cable is wound up by the take-up roller 503 to complete the entire automated braiding process.

[0046] The anti-slip texture on the surface of the knob 208 makes it easier for the operator to apply force when opening and closing the lower cylinder 201 and the upper cylinder 202, thus improving the ease of operation.
