[0030] The working principle of a stranding machine for high-frequency data cable production disclosed in the present invention is as follows: when in use, the user first installs the sub-wires to be produced at the position of the bobbin 104, selects the number of sub-wires to be installed as needed, puts all the wire ends together, and then passes them through two wire extrusion wheels 105. At this time, the feed motor 106 and the stranding motor 102 are started. The start of the feed motor 106 will drive the sub-wires to move, and the rotation of the stranding motor 102 will drive the sub-wires to rotate, thereby completing the stranding function. After the cable 3 is produced, one end is overlapped in the fork frame 315, and then the drive motor 302 is started. The output shaft of the drive motor 302 will drive the rotating seat 303 to rotate, and the rotation of the rotating seat 303 will drive the adjusting basin 305 to rotate. The rotation of the adjusting basin 305 will drive the winding rod 316 to rotate through the guide slider 313, so that the cable 3 is wound on the winding rod 316. According to the different diameters of the cable 3, the radius of the winding cable 3 is also different. Therefore, when adjusting the winding radius, the rotation speed of the drive motor 302 is increased, and the drive motor 302 will The friction wheel 309 on the adjustment basin 305 is driven to revolve. The friction wheel 309 revolves and moves outward under the action of centrifugal force. When the friction wheel 309 contacts the friction ring 301, the friction wheel 309 rotates. The rotation of the friction wheel 309 drives the driving gear 311 to rotate through the belt transmission mechanism 310. The rotation of the driving gear 311 drives the adjustment gear 304 to rotate. The rotation of the adjustment gear 304 drives the adjustment dial 314 to rotate. The rotation of the adjustment dial 314 changes the radius of the circle formed by the multiple winding rods 316, thereby changing the radius of the wound cable 3. When the winding is completed, the sliding electric cylinder 202 is controlled to move the sliding plate 204 and the lifting plate 208, so that the arc expansion frame 211 moves to the edge of the completed cable 3, and then the lifting motor 205 is controlled to rotate so that the lead screw 207 rotates. The rotation of the lead screw 207 drives the lifting plate 208 to move online. When the arc expansion frame 211 moves to the edge of the completed cable 3, the arc expansion frame 211 moves to the edge of the completed cable 3. Figure 3When the cable 3 is in the position shown (when the electromagnet 214 is started, the rod seat 215 will move upward, and the rod seat 215 drives the two arc expansion frames 211 to open through the rod 216. At this time, the electromagnet 214 is not started, so the two arc expansion frames 211 will be closed), the cable tie wire 218 overlapped at the ends of the two arc expansion frames 211 will form a U shape under the restriction of the cable 3. At this time, the cable tie wire 218 is cut off by the wire cutting mechanism 217 (the cable tie wire 218 is fed through the conveyor roller), and then the lifting motor 20 is controlled again. 5 and the electromagnet 214, so that the arc expansion frame 211 moves upward, at this time, the U-shaped cable tie wire 218 will be hung on the cable 3, and then the tightening motor 209 will be accelerated and started, and the output shaft of the tightening motor 209 will drive the central gear 220 to rotate. Because of the acceleration (in the whole process of tightening the cable tie wire 218, the output shaft of the tightening motor 209 needs to be kept in an accelerated state), the central gear 220 and the rotating disk 219 will rotate relative to each other, and at this time the central gear 220 will drive the rack 222 to move, so that the two The clamping plates 221 are closed and close to the two sides of the cable tie wire 218, and then the clamping plates 221 will rotate, so that the closing end of the U-shaped cable tie wire 218 is twisted into a spiral shape. When it is necessary to loosen it, it is only necessary to control the output shaft of the tightening motor 209 to slow down or stop it urgently. At this time, the rotating disk 219 will continue to move under the action of inertia, and the two clamping plates 221 will separate, or continue to accelerate. When the force applied by the central gear 220 to the clamping plates 221 cannot overcome the centrifugal force generated by the rotation of the clamping plates 221, the clamping plates 221 will also separate. Then stop (in addition, a friction block can be added between the rotating disk 219 and the housing of the tightening motor 209 as needed, so that the rotation between the rotating disk 219 and the tightening motor 209 will be limited by the friction block, that is, the friction between the rack 222 and the rotating disk 219 is less than the friction between the rotating disk 219 and the tightening motor 209, and the central gear 220 will drive the rack 222 to move. When the clamping plate 221 rotates, there is a sliding friction relationship between the tightening motor 209 and the rotating disk 219). When all is completed, cut off one end of the cable 3, and then control the unloading electric cylinder 319 to drive the unloading rack rotating frame 317 to rise. The rise of the unloading rack rotating frame 317 will drive the unloading rack 318 to rise. The rise of the unloading rack 318 will separate the cable 3 wound on the winding rod 316 from the winding rod 316.
