As shown in FIG. 1 and FIG. 2 , an embodiment of the present invention provides a stranding machine. The stranding machine is controlled by a cabinet for each process in the stranding production process, and is easy to operate. The stranding machine includes a stranding device 1 , a wire take-up device 2 and a wire-passing buffer device 3 . The twisting device 1 is rotated for twisting a plurality of twisted single wires into a twisted body. The "stranded single wire" refers to the wire before being twisted (such as the wire or wire used for twisting), not the wire formed after being twisted; the wire take-up device 2 is used to The wire body is collected, and the collection method can be rolled into a cylinder shape or a bundle; and the wire buffering device 3 is used to draw the stranded wire body to transfer the stranded wire body to the wire take-up device 2, Continuous collection of twisted wire bodies. At the same time, under the pulling action of the wire-passing buffer device 3, not only can the stranded wire body obtained after twisting be kept in a tensioned state, it is convenient for stable transmission to the wire take-up device 2 for collection, but also each The twisted single wire is also kept under tension to maintain a stable twisting state, ensuring that the entire twisting operation can continue and reliably proceed.

In the process of collecting and twisting the stranded single wires, it is necessary to output the stranded single wires from their respective coils by paying off first, and keep the open state so as to be able to output smoothly. In the process of opening and outputting each stranded single wire, it is necessary to maintain a tension state all the time, so as to achieve the purpose of continuous and stable twisting. Therefore, in the embodiment of the present invention, in order to ensure that the tension of each stranded single wire is kept in a stable and appropriate range, the twisting device 1 is arranged to include a device for opening the stranded single wire for output and capable of adjusting each stranded wire. Since a plurality of stranded single wires need to be provided in the twisting process, there are multiple pay-off devices 11 (refer to FIG. 1 ) with the size of the single wire tension. Close the single line to open the output. The opening output refers to opening the stranded single wire in a winding state and outputting it in a taut state. Because the pay-off 11 can accurately adjust the size of the tension, and can intuitively know the value of the size of the tension. Therefore, by being provided with the wire pay-off device 11 , the independent and accurate adjustment of the tension of the stranded single wire is realized. In addition, the accuracy and convenience of adjustment when the tension of each pay-off device 11 is kept consistent is improved, and the defect of poor accuracy existing in completely relying on human experience to keep the tension of each pay-off device 11 consistent is overcome. Since the tension of each pay-off device 11 can be adjusted to be consistent, the balanced twisting of each stranded single wire is realized, the tightness of the stranded wire body obtained after twisting is kept uniform, and the twisting process is improved. after the product quality.

As shown in FIGS. 3 and 4 , the stranding device 1 (refer to FIG. 1 ) further includes a chassis 12 , a stranding drum 13 and a stranding driving member 14 . The chassis 12 is used for the fixed installation of the wire pay-offs 11 and the stranded wire barrels 13 , and the wire pay-offs 11 are distributed on the chassis 12 and preferably fixed on the chassis 12 in a uniform distribution manner. Each stranded single wire outputted through each wire pay-off device 11 is connected to the stranded wire barrel 13 , and the stranded wire barrel 13 gathers each stranded single wire above the stranded wire barrel 13 into one. Preferably, the stranded wire drum 13 is arranged at the center of the area formed by the combination of the wire pay-off devices 11, so as to ensure the balanced force of each stranded single wire and achieve balanced twisting. During the twisting process, the chassis 12 is driven to rotate by the twisted wire driving member 14 , so that each pay-off device 11 can rotate around the twisted wire drum 13 , and at the same time, the twisted wire drum 13 itself is also synchronized with the chassis 12 Rotating, each pay-off device 11 and the stranded wire drum 13 are kept relatively still, so that the stranded wires can be finally twisted together as a whole, and the actual stranded wire body is twisted. Under the continuous pulling and pulling of the wire-passing buffer device 3, each stranded single wire can be continuously twisted, and the stranded wire body obtained by twisting is transported to the wire take-up device 2 in time for collection. In this way, the stranding machine realizes that the opening and output of the twisted single wire, the twisting, and the collection of the twisted body after twisting are kept synchronously, and the production purpose of continuous twisting work is achieved. In this embodiment, the stranded wire driving member 14 is a motor, and the rotation of the chassis 12 is realized through a belt drive.

The wire coil installation shaft 112 is fixed on the installation frame 118 and is used for connecting the wire coil wound with the stranded single wire. According to the production method, the initial state of each stranded single wire is to be wound on the wire coil. Therefore, the installation of the wire coil installation shaft 112 facilitates the loading and fixing of the wire coil, so as to realize the continuous supply of the stranded single wire. The wire wheel set 113 is fixed on the support base 111 and is used to guide the output of the stranded single wire wound on the coil, so as to ensure that the output stranded wire body can be accurately and smoothly conveyed to the stranded wire drum 13 . In the embodiment of the present invention, in order to ensure that the coil always maintains tension when the stranded single wire is output, and to avoid the loosening of the coil, the coil installation shaft 112 is connected to a tension adjuster for adjusting the output tension of the stranded single wire. device 114. The tension adjuster 114 generates a torsion force opposite to the output direction of the twisted single wire, and the torsion force directly acts on the wire coil, so that in the process of winding and paying off the wire, the output twisting caused by the too fast rotation of the wire coil can be avoided. If the single wire is loose, the stranded single wire is always in a tensioned state to ensure the stability and smoothness of the output.

The above-mentioned setting of the tension adjuster 114 realizes the accurate adjustment of the output tension of the stranded single wire, and the tension adjuster 114 has a scale that directly displays the tension. In this way, in the tension adjustment operation, after the tension of one pay-off 11 is adjusted, other pay-offs 11 can be adjusted with reference to this value, which improves the efficiency and accuracy of tension adjustment of each pay-off 11 . Eliminate the error of adjusting the tension by relying on experience and feel, which brings about the problem of unstable product quality. The tension of each stranded single wire is consistent, realizing balanced stranded wire.

As shown in FIG. 5 , the tension adjuster 114 includes a body 1141 and a resistance adjusting member 1143 . The main body 1141 is connected to the mounting frame 118 for generating a torsional force opposite to the output direction of the stranded single wire, and the main body 1141 is connected to the wire reel mounting shaft 112 through a connecting piece 1144, which can be a coupling or a connecting sleeve Wait. The resistance adjusting member 1143 is arranged on the main body 1141, and is used for adjusting the magnitude of the torsion force generated by the main body 1141, so as to meet the different demands of the twisted wire tension in the production of different types of stranded wire bodies. In this embodiment, the tension adjuster 114 is a magnetic damper, which can provide stable and balanced torsion force, and the adjustment of the torque size is convenient.

As shown in FIG. 5 , the wire wheel set 113 includes a first guide wheel 1131 , a second guide wheel 1132 and a guide assembly 1133 .

In addition, the first guide wheel 1131 and the second guide wheel 1132 are both fixedly connected to the support base 111 through the connecting frame 115 , and the guide assembly 1133 is disposed above the coil through the support plate 116 . With this arrangement, during the winding connection, the stranded single wire output from the coil is first wound on the first guide wheel 1131, then wound on the second guide wheel 1132, and finally passed through the guide assembly 1133 to connect with the first guide wheel 1131. The spool 13 is connected. The output of the stranded single wire is stable and smooth after being guided by various components in the wire wheel set 113 . In this embodiment, the first guide wheel 1131 and the second guide wheel 1132 are ceramic rings, and the ceramic rings have smooth surfaces and low hardness. In this way, the ceramic ring can not only provide guidance for the output of the twisted single wire, but also ensure that the twisted single wire will not be damaged during the process of winding and sliding on the ceramic ring.

As shown in FIG. 5 , the first guide wheel 1131 and the second guide wheel 1132 are fixedly supported by using the connecting frame 115 , and the connecting frame 115 is connected with the support base 111 . Therefore, the mounting bracket 118 can be fixed on the connecting bracket 115 by adopting, and the fixed installation of the mounting bracket 118 can also be realized.

As shown in FIG. 5 , in the embodiment of the present invention, two opposing rails 117 are arranged on the mounting frame 118 , and the stranded single wire output from the coil is passed between the two rails 117 . It is then wound on the first guide wheel 1131. In this way, under the limiting action of the two retaining bars 117 , it is ensured that the position where the stranded single wire is wound on the first guide wheel 1131 remains relatively stable and will not fall off from the first guide wheel 1131 .

As shown in FIG. 3 and FIG. 4 , the twisted wire device 1 further includes a detection switch 15 and a disconnection detection component 16 . The detection switch 15 is arranged adjacent to the support base 111 through the support rod 18 . The disconnection detection assembly 16 is movably connected to the mounting frame 118 (refer to FIG. 5 ) for compressing the stranded single wire, and can touch the detection switch 15 when the wire is disconnected, trigger the detection switch 15 to realize power off and stop twisted. 5 , the wire breakage detection assembly 16 includes a crimping wheel 161 for pressing the stranded single wire, a contact rod 162 for contacting the detection switch 15 , a torsion spring 163 , an adjusting gear 164 and a mounting rod 165 .

The torsion spring 163 is sleeved on the mounting rod 165 , the adjusting gear 164 is connected to one end of the mounting rod 165 , and is combined with the lever 166 to realize the adjustment of the torsion force generated by the torsion spring 163 , and the mounting rod 165 is connected to the mounting frame 118 , which is supported and fixed by the mounting bracket 118 . In this way, the torsion spring 163 generates pressure so that the pressing wheel 161 is pressed on the twisted single wire, and the twisted single wire is pressed tightly. At this time, the touch rod 162 is raised and cannot touch the detection switch 15 during the rotation process. touch. When the stranded single wire is disconnected, the crimping wheel 161 will descend, thereby driving the touch rod 162 to descend, so that the position of the touch rod 162 can touch the detection switch 15 . After the contact with the detection switch 15 occurs during the rotation, the circuit connected to the detection switch 15 will form a loop at this time, which plays the role of reminding the disconnection.

In this way, in the specific back-twisting process, the driving force generated by the back-twisting driving member 171 is transmitted to the driving gear 172 through the back-twisting transmission member, and the rotation of the driving gear 172 can drive the transition gear 174 to rotate, and then under the transmission action of the transition gear 174 , so that each planetary gear 173 rotates at the same time, and then each support seat can be rotated to realize the back-twisting of each stranded single wire. In this way, the back-twisting is carried out by means of mutual meshing transmission between gears, and the synchronization is good, ensuring that each pay-off device 11 can rotate at the same time, and realizing the synchronous back-twisting.

As shown in FIG. 3 and FIG. 6 , in the embodiment of the present invention, ten wire payoffs 11 are provided on the chassis 12 . Therefore, it can be realized by sharing a transition gear 174 between every two planetary gears 173 .

In the actual setting, the set number of the wire pay-offs 11 in the upper and lower stranding devices 1 can be selected according to specific production requirements, which can be the same or different. In the embodiment of the present invention, referring to FIG. 3 and FIG. 4 , the structural difference between the upper and lower stranded wire devices is that the number of wire pay-off devices 11 is different, and the stranded wire device 1 located on the upper layer is provided with ten wire pay-off devices 11, The stranded wire device 1 located on the lower level is provided with three wire payoffs 11 . Of course, it can be understood that in the actual stranding process, not all the wire pay-offs 11 must be twisted at the same time, and the number of each wire pay-off 11 used can be selected according to the actual stranding requirements. At the same time, the stranding machine can set the number of stranding devices 1 according to the specific stranding type requirements, not only two stranding devices are arranged in layers, but also three or four other stranding devices are arranged in layers. number. In addition, the working mode of each stranding device 1 can also be selected as required, and each stranding device 1 can be twisted at the same time, or one can be selected to perform the stranding work independently. Moreover, when two or more twisting devices 1 are used for twisting at the same time, the twisting directions can be reversed in sequence, or they can be the same. limited.

Through this arrangement, each stranded single wire can be assembled in the wire hole 521, so that during the twisting process, the wire hole 521 can define the final twisted position of each stranded single wire. In this way, under the driving of the carriage driving member 53 , the position of the carriage 51 can be adjusted as required, thereby realizing the adjustment of the position of the wire die 52 . When the wire mold 52 is far away from the stranded wire barrel 13 , the tightness of the obtained stranded wire body is looser; and when the wire mold 52 is close to the stranded wire barrel 13 , the stranded wire body is relatively tight. In this way, the twisting of different types of stranded wire bodies is realized, and the production azimuth is wide.
