Description

Technical Field

[0001] The invention relates to the technical field of fully automatic wire stranding equipment for composite cable production, and in particular to a fully automatic wire stranding device and method for composite cable production. Background Art

[0002] Stranded wire refers to two or more strands of wire wrapped around each other. The most commonly used ones are copper and aluminum. Copper and aluminum wires can be twisted into conductors and cable cores of various specifications and cross-sections as well as different types of wires and cables. The twisting device used in twisting the wires is mostly composed of a twisting mechanism and a winding mechanism, which are used to wind and collect the processed inner cores to complete the twisting work.

[0003] In the fully automatic wire twisting device under the existing technology, when the copper wires are twisted, most of the rotating shafts for placing the copper wires rotate freely. When the copper wires are twisted quickly, it is not easy to control the speed of the rotating shaft for placing the copper wires. When the rotating speed of the rotating shaft for placing the copper wires is fast and the output of the copper wires is large, it is easy to cause the tension of the copper wires to be low. The low tension of the copper wires can easily cause several copper wires to be entangled and overlapped. Summary of the invention

[0012] The method of the fully automatic stranding device for producing composite cables comprises the following steps: S1: Rotary twisting, the pay-off shaft arranged on the passive gear rotates with the passive gear, at this time, the copper wire wheel on the pay-off shaft rotates, and the copper wire on the copper wire wheel passes through the reversing wheel in the sliding frame, and at this time, the copper wire passes through the small hole on the tightening disk, and several copper wires pass through the small holes on the tightening disk and converge into the small holes on the tightening plate, so that the arrangement is conducive to limiting the position of several copper wires to prevent the several copper wires from being entangled with each other during the twisting process, and the several copper wires passing through the tightening plate are driven by the rotation of the rotary twisting mechanism to form a finished cable; S2: The tension is tightened. By setting the direction-changing wheel in the tensioning mechanism, the tensioning spring squeezes the direction-changing wheel on the sliding block 1, and the direction-changing wheel is squeezed by the elastic force of the tensioning spring and slides forward along the sliding frame. This arrangement is conducive to tightening the copper wire; S3: Product winding, the rotating shaft rotates to drive the bevel gear 1 to rotate, the bevel gear 1 rotates to drive the rotating shaft 1 on the bevel gear 2 to rotate, the rotating shaft 1 rotates to drive the rotating shaft 2 at one end of the transmission belt to rotate, the rotating shaft 2 rotates to drive the cable storage wheel to rotate, and the cable storage wheel rotates to store the finished cable; S4: Control the rotation speed, and use the centrifugal force of the centrifugal sliding block to slide outward along the centrifugal sliding groove to drive the friction block in the control mechanism to generate friction with the surface of the pay-off shaft, so that the pay-off shaft is damped during rotation.

[0013] The present invention has the following beneficial effects: (1) The present invention sets a control mechanism. When the driven gear rotates at a faster speed, the centrifugal sliding block slides outward along the centrifugal sliding groove under the action of centrifugal force. The centrifugal sliding block drives the extrusion sliding block at one end of the linkage rod to slide along the clamping sliding groove toward one end close to the pay-off shaft. The extrusion sliding block drives the telescopic rod to contract. At this time, the pressure spring on the telescopic rod is squeezed and contracted. When the pressure spring contracts, the elastic force of the pressure spring increases. The pressure spring contracts and controls the sliding block to slide outward along the friction block. At this time, the ball is away from the surface of the pay-off shaft, and the side of the friction block close to the pay-off shaft generates sliding friction with the surface of the pay-off shaft. When the friction block and the surface of the pay-off shaft are When friction occurs on the surface, the pay-off shaft is constrained, and the rotation damping of the pay-off shaft increases. This arrangement is conducive to controlling the rotation speed of the pay-off shaft, thereby avoiding excessive rotation speed of the pay-off shaft and excessive output of copper wire on the copper wire wheel; when the passive gear rotates slowly, the displacement of the centrifugal sliding block is small, and the contraction of the pressure spring is small. At this time, the ball on the control slider maintains a rolling connection with the surface of the pay-off shaft, while the friction block does not contact the surface of the pay-off shaft. This arrangement is conducive to ensuring that when the passive gear is twisted at a low speed, the friction generated by the pay-off shaft is small, and the heat generated by the rolling friction between the ball and the pay-off shaft is small.

[0014] (2) In the present invention, when the fully automatic wire twisting device is used, the driving motor is started, and the output end of the driving motor drives the rotating shaft to rotate. The rotation of the rotating shaft drives the driving gear to rotate. The rotation of the driving gear drives the driven gear to rotate. At this time, the driven gear drives the connecting column at one end of the rotating cylinder to rotate. By arranging the connecting column at one end of the rotating cylinder, it is beneficial to ensure that the driven gear on the rotating cylinder rotates stably. The wire-releasing shaft arranged on the driven gear rotates with the driven gear. At this time, the copper wire wheel on the wire-releasing shaft rotates, and the copper wire on the copper wire wheel passes through the turning wheel in the sliding frame. At this time, the copper wire passes through the small hole on the tightening disk. Several copper wires pass through the small holes on the tightening disk and merge into the small holes on the tightening plate. This arrangement is beneficial to limit the several copper wires to prevent the several copper wires from being entangled with each other during the twisting process. The several copper wires passing through the tightening plate are driven by the rotation of the rotating wire twisting mechanism to form a finished cable.

[0015] (3) The present invention provides a tensioning mechanism. When a plurality of copper wires are twisted together, the copper wires are pulled to generate tension. In order to ensure that the copper wires always maintain a large tension, a reversing wheel is provided in the tensioning mechanism. The tensioning spring squeezes the reversing wheel on the sliding block. The reversing wheel is squeezed by the elastic force of the tensioning spring and slides forward along the sliding frame. This arrangement is conducive to tightening the copper wires and avoiding the copper wires from being loosened due to too small tension, thereby ensuring that the plurality of copper wires are always tightened during the twisting process and ensuring the twisting quality of the device.

[0016] (4) The present invention provides an auxiliary mechanism. When the driven gear rotates at a faster speed, the centrifugal sliding block slides outward along the centrifugal sliding groove under the action of centrifugal force. The centrifugal sliding block drives the connecting rod at one end of the linkage rod 2 to move. The connecting rod drives the sliding block 2 to squeeze the tensioning spring along the sliding frame. At this time, the tensioning spring is squeezed and contracted by the sliding block 2. The elastic force of the sliding block 2 increases, and the squeezing force of the sliding block 2 on the sliding block 1 increases. The squeezing force of the sliding block on the copper wire on the turning wheel increases. This arrangement is conducive to further tightening the copper wire on the turning wheel and further increasing the tension of the copper wire.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Embodiment 2 is different from Embodiment 1 in that: Figure 1 - Fig.10As shown, a control mechanism 6 is provided on one side of the passive gear 204, and the control mechanism 6 includes a plurality of centrifugal sliding grooves 601 opened on the side of the passive gear 204 away from the rotating cylinder 14, and a plurality of clamping sliding grooves 602 are opened on the side of the passive gear 204 away from the rotating cylinder 14. A centrifugal sliding block 603 is slidably connected in the centrifugal sliding groove 601, and a plurality of extrusion sliding blocks 604 are slidably connected in the clamping sliding groove 602. One end of the centrifugal sliding block 603 is rotatably connected to a plurality of linkage rods 605, and one end of the linkage rod 605 away from the centrifugal sliding block 603 is rotatably connected to the extrusion sliding block 604.

The function of this component is to set the auxiliary mechanism 7, so that when the driven gear 204 rotates faster, the centrifugal sliding block 603 slides outward along the centrifugal sliding groove 601 under the action of centrifugal force, and the centrifugal sliding block 603 The connecting rod 702 at one end of the linkage rod 2 701 is driven to move, and the connecting rod 702 drives the sliding block 2 304 to squeeze the tensioning spring 303 along the sliding frame 301. At this time, the tensioning spring 303 is squeezed and contracted by the sliding block 2 304, and the elastic force of the sliding block 2 304 increases. The squeezing force of the sliding block 2 304 on the sliding block 1 302 increases, and the squeezing force of the sliding block 1 302 on the copper wire 207 on the changing wheel 305 increases.

By setting the direction-changing wheel 305 in the tensioning mechanism 3, the tensioning spring 303 squeezes the direction-changing wheel 305 on the sliding block 1 302. The direction-changing wheel 305 is squeezed by the elastic force of the tensioning spring 303 and slides forward along the sliding frame 301.

The passive gear 204 rotates, and the copper wire wheel 206 on the wire-releasing shaft 205 rotates. The copper wire 207 on the copper wire wheel 206 passes through the reversing wheel 305 in the sliding frame 301. At this time, the copper wire 207 passes through the small hole on the tightening disk 402. Several copper wires 207 pass through the small holes on the tightening disk 402 and then flow into the small holes on the tightening plate 403. This arrangement is conducive to limiting the position of several copper wires to prevent the several copper wires 207 from being entangled with each other during the twisting process. The finished cable 508 is formed under the rotation of the rotating twisting mechanism 2; the rotation of the rotating shaft 201 drives the bevel gear 1 501 to rotate, the rotation of the bevel gear 1 501 drives the rotating shaft 1 503 on the bevel gear 2 504 to rotate, the rotation of the rotating shaft 1 503 drives the rotating shaft 2 506 at one end of the transmission belt 505 to rotate, the rotation of the rotating shaft 2 506 drives the cable storage wheel 507 to rotate, and the cable storage wheel 507 rotates to store the finished cable 508; by setting the tensioning mechanism 3, when a plurality of copper wires 207 are in the process of twisting, the copper wires 207 is pulled to generate tension. In order to ensure that the copper wire 207 always maintains a large tension, a change-direction wheel 305 is provided in the tensioning mechanism 3. The tensioning spring 303 squeezes the change-direction wheel 305 on the sliding block 1 302. The change-direction wheel 305 is squeezed by the elastic force of the tensioning spring 303 and slides forward along the sliding frame 301. This arrangement is conducive to tightening the copper wire 207 and avoiding the copper wire 207 from being loosened due to too small tension, thereby ensuring that the copper wires 207 are always tightened during the twisting process, and ensuring the twisting quality of the device; By setting the control mechanism 6, when the driven gear 204 rotates faster, the centrifugal sliding block 603 slides outward along the centrifugal sliding groove 601 under the action of centrifugal force, and the centrifugal sliding block 603 drives the extrusion sliding block 604 at one end of the linkage rod 605 to slide along the clamping sliding groove 602 toward the end close to the line-releasing shaft 205, and the extrusion sliding block 604 drives the telescopic rod 607 to contract. At this time, the pressure spring 610 on the telescopic rod 607 is squeezed and contracted. When the pressure spring 610 contracts, the elastic force of the pressure spring 610 increases, and the pressure spring 610 contracts to control the slider 609 to move along the friction When the friction block 608 and the surface of the pay-off shaft 205 produce friction, the pay-off shaft 205 is restrained, and the rotation damping of the pay-off shaft 205 increases. This arrangement is conducive to controlling the rotation speed of the pay-off shaft 205, thereby avoiding the pay-off shaft 205 from rotating too fast and avoiding the phenomenon of excessive output of the copper wire 207 on the copper wire wheel 206. When the passive gear 204 rotates slowly, The displacement of the centrifugal sliding block 603 is small, and the contraction of the pressure spring 610 is small. At this time, the ball 611 on the control slider 609 maintains rolling connection with the surface of the pay-off shaft 205, while the friction block 608 does not contact the surface of the pay-off shaft 205. This arrangement is conducive to ensuring that when the passive gear 204 is twisted at a low speed, the friction generated by the pay-off shaft 205 is small, and the heat generated by the rolling friction between the ball 611 and the pay-off shaft 205 is small; by setting the auxiliary mechanism 7, when the passive gear 204 rotates faster, the centrifugal sliding block 603 is subjected to the centrifugal force and moves along the centrifugal sliding groove 6 01 slides outward, the centrifugal sliding block 603 drives the connecting rod 702 at one end of the linkage rod 2 701 to move, and the connecting rod 702 drives the sliding block 2 304 to squeeze the tensioning spring 303 along the sliding frame 301. At this time, the tensioning spring 303 is squeezed and contracted by the sliding block 2 304, and the elastic force of the sliding block 2 304 increases. The squeezing pressure of the sliding block 2 304 on the sliding block 1 302 increases, and the squeezing pressure of the sliding block 1 302 on the copper wire 207 on the changing wheel 305 increases. This arrangement is conducive to further tightening the copper wire 207 on the changing wheel 305, and is conducive to further increasing the tension of the copper wire 207.
