DETAILED DESCRIPTION

[0032] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0033] In the description of this application, it should be noted that for directional words, such as the terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and so on, the directions and positional relationships indicated are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of this application.

[0034] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0035] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or units is not necessarily limited to those steps or units expressly listed, but may include other steps or units not expressly listed or inherent to such process, method, product or apparatus.

[0036] One aspect of the present application provides a rewinding transmission structure, such as Figure 1 and Figure 2 As shown, one preferred embodiment includes a main shaft 112, a wire storage drum 12, a clutch mechanism 13, and a reversing mechanism 15. The main shaft 112 is rotatably mounted on the frame 100 and can rotate under the drive of the transmission mechanism 11 mounted on the frame 100. A wing tension control mechanism 14 for tensioning the wire 220 is also mounted on the main shaft 112. The wire storage drum 12 is mounted on the main shaft 112 via a clutch mechanism 13 and is located on one side of the wing tension control mechanism 14. The wire storage drum 12 is rotatably mounted on the main shaft 112 and is equipped with multiple wire storage boxes 122. The wire storage boxes 122 can pay out wire to the wing tension control mechanism 14 via corresponding guide wheels 123 mounted on the wire storage drum 12. The clutch mechanism 13 can drive the wire storage drum 12 to disengage from the main shaft 112 when the wire storage boxes 122 on the wire storage drum 12 need to be rewound. The reversing mechanism 15 is installed on one side of the wire storage drum 12. When the wire storage drum 12 is disengaged from the main shaft 112, the reversing mechanism 15 can reversely drive the main shaft 112 and the wire storage drum 12, thereby driving the wire storage box 122 to rotate and rewind the wire.

[0037] It should be noted that the specific structure of the wing tension control mechanism 14 is a well-known technology for those skilled in the art, so it will not be elaborated on here. By connecting the wire storage disk 12 and the main shaft 112 through the clutch mechanism 13, when it is necessary to rewind the wire storage box 122 on the wire storage disk 12, the wire storage disk 12 can be separated from the main shaft 112 without stopping the main shaft 112 and the wire storage box 122 can be driven in reverse by the main shaft 112 to achieve rewinding. This can effectively reduce the downtime of the stranding machine and improve the production efficiency of the stranding machine. The specific number of wire storage boxes 122 can be determined according to the number of wires 220 required for actual stranding; for example Figure 6 As shown, there are six wire storage boxes 122 , and each wire storage box 122 can pay out a single wire 220 or a multiple wire formed by multiple wires 220 .

[0038] It is understandable that the number of the wire storage drum 12 can be one, then after the wire storage drum 12 completes the wire unwinding, the main shaft 112 can only be rewound without stopping; compared with the entire production process, the efficiency that can be improved is limited. Therefore, in order to further improve production efficiency, the wire storage drum 12 can be set as a pair. Figures 1 to 3 As shown, two wire storage drums 12 can be installed along the axial sides of the wing tension control mechanism 14, and each wire storage drum 12 can be installed with the main shaft 112 through the clutch mechanism 13. The two wire storage drums 12 can pay out the wire alternately; when one of the wire storage drums 12 pays out the wire, it means that the other wire storage drum 12 has completed all the wire paying out. At this time, the other wire storage drum 12 can be driven by the clutch mechanism 13 to decouple from the synchronous rotation with the main shaft 112, so that the wire storage drum 12 can be rewound by reverse rotation. Therefore, when the working wire storage drum 12 has also completed all the wire paying out, the wire 220 in the wire storage drum 12 that has been rewound can be directly connected to the wing tension control mechanism 14 after the stranding machine is stopped. Figure 3 The reversing wiring shown is sufficient, and then the stranding machine can be restarted to continue working. Compared with the traditional shutdown winding method, this application can greatly shorten the downtime of the stranding machine, thereby effectively improving the working efficiency of the stranding machine.

[0039] It is understandable that the traditional stranding machine operates in the following manner: stranding - stopping - winding - connection - stranding; however, after adopting the technical solution of the present application, the stranding machine operates in the following manner: stranding (synchronous winding) - stopping - connection - stranding (synchronous winding). Compared with the traditional method, the present application can reduce the time of one winding process, thereby effectively shortening the stranding machine's downtime and improving the stranding machine's production efficiency.

[0040] Specifically, such as Figure 1 and Figure 2 As shown, the transmission mechanism 11 includes a main shaft 112 and a first rotating device 111; the main shaft 112 can be rotatably mounted on the frame 100, and the first rotating device 111 is fixedly mounted on the frame 100 and is transmission-connected to the main shaft 112 via the output end, so that the main shaft 112 rotates under the drive of the first rotating device 111. There are many transmission structures for the first rotating device 111 and the main shaft 112, the most common of which are gear transmission, belt transmission, and chain transmission. Since the overall weight of the twisting module 1 is relatively large, it is not suitable for rigid starting of the main shaft 112, so a belt transmission is preferably used for the transmission structure of the main shaft 112. The specific structure and working principle of the first rotating device 111 are well known to those skilled in the art. A motor is commonly used, and the specific power can be selected according to actual needs.

[0041] In this embodiment, there are many specific structures of the clutch mechanism 13 that can achieve the above functions, one of which is as follows: Figures 4 to 10 As shown, the main shaft 112 is provided with an outer ring gear 1121 at the corresponding mounting position of the storage drum 12. The clutch mechanism 13 includes a clutch sleeve 131, a traction assembly 133, and a brake assembly 134. The clutch sleeve 131 is slidably mounted on the main shaft 112 and engages with the outer ring gear 1121 on the main shaft 112 through internal gear teeth 1312 disposed on its inner side, forming an axial spline connection. This allows the clutch sleeve 131 to rotate synchronously with the main shaft 112 while also sliding back and forth axially along the main shaft 112. The storage drum 12 is rotatably mounted on the main shaft 112 through a second inner hole 1210 in its center. Furthermore, the second inner hole 1210 also engages with the outer gear teeth 1311 disposed on the outer side of the clutch sleeve 131 through an inner ring gear 1211 disposed on the sidewall, forming an axial spline connection. The traction assembly 133 is mounted on the frame 100 and cooperates with the clutch sleeve 131 , and the brake assembly 134 is mounted on the frame 100 to cooperate with the wire storage drum 12 for braking.

[0042] When the storage drum 12 is in the process of paying out the line, the clutch sleeve 131 remains in meshing engagement with the inner gear ring 1211 of the inner hole of the storage drum 12, so that the storage drum 12 can rotate synchronously with the main shaft 112 through the clutch sleeve 131, thereby achieving relative stillness in the circumferential direction with the wing tension control mechanism 14 for paying out the line. When the storage drum 12 has completed all the paying out and needs to be rewound, the traction assembly 133 can drive the clutch sleeve 131 to slide axially along the main shaft 112 in a direction away from the storage drum 12 until the outer gear 1311 of the clutch sleeve 131 is disengaged from the inner gear ring 1211 of the inner hole side wall of the storage drum 12. At this time, the storage drum 12 is in a disengaged state from the main shaft 112, but the corresponding other storage drum 12 is in a paying out state. The wire storage drum 12 that is separated from the main shaft 112 can then be braked by the brake assembly 134, so that the wire storage drum 12 in the separated state can be quickly stopped, thereby facilitating subsequent reverse rotation to achieve rewinding.

[0043] It should be known that, assuming that the wire storage drum 12 is in a forward rotating state when paying out the wire, the wire storage drum 12 needs to be driven to rotate in the reverse direction when rewinding the wire so that the rewound wire 220 can be smoothly paid out when the wire storage drum 12 rotates forward subsequently.

[0044] It can be understood that the overall mass of the wire storage disc 12 is relatively large. After the wire storage disc 12 is separated from the main shaft 112 through the clutch mechanism 13, since the wire storage disc 12 and the main shaft 112 are rotated together through bearings, the rotational friction of the wire storage disc 12 is relatively small, and the wire storage disc 12 will continue to rotate under its own large rotational inertia. Therefore, it is necessary to set a brake assembly 134 to quickly brake the wire storage disc 12 that is separated from the main shaft 112, so as to quickly rewind the wire storage box 122 on the wire storage disc 12.

[0045] In this embodiment, there are many specific structures of the brake assembly 134 that can achieve the above-mentioned braking function. For the sake of easy understanding, the following will be described in detail using one of the structures. Figure 5 and Figure 6 As shown, the cable storage drum 12 has an annular extension 1212 disposed on at least one side of the drum body 121. The extension 1212 is concentric with the second inner hole 1210 of the drum body 121. A brake assembly 134 can be mounted on the mounting bracket 110 of the frame 100, such that the brake assembly 134 and the extension 1212 are at the same height. The brake assembly 134 includes a second telescopic device 1341 and a brake block 1343. The second telescopic device 1341 is fixedly mounted on the mounting bracket 110. The brake block 1343 is fixedly mounted on a connecting bracket 1342 at the output end of the second telescopic device 1341. The connecting bracket 1342 can slideably engage with a guide slot 1102 provided on the mounting bracket 110 to enhance stability. When the cable storage drum 12 needs to be disconnected from the spindle 112, the brake block 1343, driven by the second telescopic device 1341, can approach and engage the extension 1212, thereby braking the cable storage drum 12 after it is disconnected from the spindle 112.

[0046] It should be understood that in order to ensure that the braking assembly 134 brakes the wire storage disc 12 stably, the number of brake blocks 1343 can be multiple, for example Figure 6 As shown, there are two brake blocks 1343, and the two brake blocks 1343 can simultaneously make frictional contact with the extension portion 1212. The specific structure and working principle of the second telescopic device 1341 are well known to those skilled in the art. Common second telescopic devices 1341 are air cylinders or hydraulic cylinders.

[0047] In this embodiment, there are many specific structures of the traction assembly 133 that can achieve the above functions. For the sake of easy understanding, the following will be described in detail using one of the structures. Figures 6 to 10As shown, the clutch sleeve 131 is elastically slidably mounted on the main shaft 112, and a connecting groove 1310 is provided on one side of the clutch sleeve 131 along the circumferential direction. The traction assembly 133 is mounted on the mounting frame 110 on the frame 100 so that the traction assembly 133 is at the same height as the clutch sleeve 131. The traction assembly 133 includes a connecting sleeve 1331, a traction frame 1332, and a first telescopic device 1336. The connecting sleeve 1331 can be rotatably mounted on the connecting groove 1310 on the clutch sleeve 131 by means of a bearing fit. The traction frame 1332 is rotatably fitted with the support pin 1101 on the mounting frame 110 through a strip-shaped rotating groove 1333 in the middle; one end of the traction frame 1332 is hinged to the connecting sleeve 1331, and the other end of the traction frame 1332 is provided with a strip-shaped traction groove 1334. The first telescopic device 1336 is installed on the frame 100, and the output end of the first telescopic device 1336 is hinged to the traction groove 1334 through the traction plate 1335, so that the traction frame 1332 rotates around the rotation groove 1333 under the drive of the first telescopic device 1336, and then the traction connecting sleeve 1331 drives the clutch sleeve 131 to move axially back and forth along the main shaft 112.

[0048] It should be known that there are many specific elastic sliding installation methods for the clutch sleeve 131; for ease of understanding, a specific example is shown below. Figure 4 、 Figure 6 and Figure 10 As shown, a radially extending baffle 1123 is provided on the main shaft 112, and a plurality of guide rods 1313, such as four guide rods 1313, are provided at equal intervals along the circumferential direction on the end surface of the clutch sleeve 131 away from the wire storage drum 12. The guide rods 1313 can slide through the baffle 1123 on the main shaft 112, and a spring 132 is sleeved on each of the guide rods 1313. The ends of the spring 132 respectively abut against the baffle 1123 and the end surface of the clutch sleeve 131, thereby achieving elastic sliding installation between the clutch sleeve 131 and the main shaft 112.

[0049] In order to ensure the traction stability of the clutch sleeve 131, the traction frame 1332 and the connecting sleeve 1331 have at least two hinge points, and the connecting lines of the multiple hinge points can intersect at the center point of the connecting sleeve 1331. Figure 6As shown, the connecting end of the traction frame 1332 is in a "U" shape, so that the traction frame 1332 can be hinged with the hinge rod arranged at the upper and lower limit height positions of the connecting sleeve 1331, thereby ensuring that the traction frame 1332 drives the upper and lower ends of the connecting sleeve 1331 simultaneously during rotation to improve the stability of traction. At the same time, since the connecting sleeve 1331 always remains stationary in the circumferential direction, and the clutch sleeve 131 always rotates together with the main shaft 112, in order to reduce the friction between the connecting sleeve 1331 and the clutch sleeve 131, the connecting sleeve 1331 and the connecting groove 1310 can be connected through bearings or balls, so that the sliding friction becomes rolling friction to reduce wear.

[0050] It should also be known that since the movement of the clutch sleeve 131 is along the axial direction of the main shaft 112, that is, the movement path of the clutch sleeve 131 is a straight line; while the traction frame 1332 rotates around the support pin 1101, that is, the movement path is an arc; therefore, in order to ensure that the operation between the traction frame 1332 and the clutch sleeve 131 does not interfere, the rotating groove 1333 needs to be set as a strip shape, so that while the traction frame 1332 rotates around the support pin 1101, the trajectory difference between the traction frame 1332 and the clutch sleeve 131 can be compensated by the sliding of the rotating groove 1333 relative to the support pin 1101.

[0051] It can be understood that since the clutch sleeve 131 meshes with the internal gear ring 1211 of the inner hole of the wire storage disc 12 through the external gear teeth 1311; when the clutch sleeve 131 needs to be re-connected to the wire storage disc 12 for transmission, it may occur that the gear teeth and gaps of the external gear teeth 1311 and the internal gear ring 1211 do not correspond, which may interfere with the reset of the clutch sleeve 131. Therefore, in this embodiment, the clutch sleeve 131 is elastically slidably connected to the main shaft 112, and the traction frame 1332 and the traction plate 1335 are hinged through a strip-shaped traction groove 1334. When the gear teeth and gaps of the external gear teeth 1311 and the internal gear ring 1211 do not correspond, the first telescopic device 1336 can be reset to a state close to the initial position through the sliding of the traction plate 1335 relative to the traction groove 1334, and then as the main shaft 112 rotates relative to the wire storage disc 12 to make the gear teeth and gaps of the external gear teeth 1311 and the internal gear ring 1211 correspond, the clutch sleeve 131 can be reset under the elastic force of the spring 132 to realize the re-connection of the clutch sleeve 131 and the wire storage disc 12. At this time, the traction frame 1332 rotates around the support pin 1101, and the traction plate 1335 can slide along the traction groove 1334 again to avoid interference. In order to ensure that the elastic force of the spring 132 is sufficient, the spring 132 can be a rectangular elastic body. The specific structure and working principle of the first telescopic device 1336 are well-known technologies to those skilled in the art, so they will not be elaborated in detail here. The common first telescopic device 1336 can use a cylinder or a hydraulic cylinder.

[0052] For ease of understanding, the specific working process of the traction assembly 133 will be described in detail below with reference to the accompanying drawings.

[0053] Initially, if Figure 7 and Figure 10 As shown in (1), the clutch sleeve 131 is meshed with the inner gear ring 1211 of the storage disc 12 through the outer gear 1311. At the same time, the traction frame 1332 can be in a state perpendicular to the axial direction of the main shaft 112 and remain connected to the connecting sleeve 1331; the rotation groove 1333 can correspond to the support pin 1101 through the middle or the end away from the clutch sleeve 131; the traction plate 1335 corresponds to the end of the traction groove 1334 close to the clutch sleeve 131, and the first telescopic device 1336 is close to the clutch sleeve 131, so that the traction plate 1335 is tilted in the direction away from the clutch sleeve 131 to avoid a dead point. At the same time, the spring 132 can be in a natural state or in an elastic deformation state.

[0054] When the wire storage drum 12 needs to be separated from the main shaft 112, as shown in FIG. Figure 8 and Figure 10 As shown in (2), the first telescopic device 1336 can drive the traction plate 1335 to extend, so that the traction plate 1335 can first slide along the traction groove 1334 to the end of the corresponding traction groove 1334 away from the clutch sleeve 131, and then the traction plate 1335 and the traction groove 1334 are abutted to drive the traction frame 1332 to rotate around the support pin 1101 and slide relatively accordingly, so that the clutch sleeve 131 is driven by the connecting sleeve 1331 to slide axially in the direction away from the wire storage disk 12 until the outer gear 1311 is disengaged from the inner gear ring 1211; at this time, the wire storage disk 12 is disengaged from the main shaft 112, and the spring 132 is in an elastically compressed state.

[0055] When the accumulator 12 has finished rewinding and is ready to be connected to the spindle 112 again, as shown in FIG. Figure 9As shown, the first telescopic device 1336 can drive the traction plate 1335 to retract, so that the traction plate 1335 can slide along the traction groove 1334 to the end close to the clutch sleeve 131. During this process, if the outer gear teeth 1311 and the inner gear ring 1211 are aligned, the clutch sleeve 131 can be restored to the meshing state of the outer gear teeth 1311 and the inner gear ring 1211 under the elastic force of the spring 132. During this process, if the outer gear teeth 1311 and the inner gear ring 1211 do not correspond to each other, the first telescopic device 1336 can remain stationary when the traction plate 1335 corresponds to the traction groove 1334 and is close to the end of the clutch sleeve 131, until the wire storage disk 12 and the main shaft 112 rotate relative to each other until the outer gear teeth 1311 and the inner gear ring 1211 are exactly aligned. The clutch sleeve 131 can be restored to the meshing state of the outer gear teeth 1311 and the inner gear ring 1211 under the elastic force of the spring 132, and the first telescopic device 1336 can also be restored to its initial position. Generally speaking, when the first telescopic device 1336 drives the traction plate 1335 to move along the traction groove 1334 away from one end of the clutch sleeve 131 toward the end close to the clutch sleeve 131, the wire storage disk 12 and the main shaft 112 have already performed a relative movement of a certain angle. During this process, the outer gear 1311 and the inner gear ring 1211 can basically correspond exactly, so that the clutch sleeve 131 can re-engage with the inner gear ring 1211 under the elastic force of the spring 132. The reset drive of the first telescopic device 1336 can ensure that the clutch sleeve 131 can definitely be reset to the initial position.

[0056] Specifically, such as Figures 6 to 10 As shown, at least one side of the disc body 121 is provided with an annular extension 1212, which is concentric with the second inner hole 1210 of the disc body 121. The brake assembly 134 can be mounted on the mounting bracket 110 on the frame 100, so that the brake assembly 134 and the extension 1212 are at the same height. The brake assembly 134 includes a second telescopic device 1341 and a brake block 1343. The second telescopic device 1341 is fixedly mounted on the mounting bracket 110, and the brake block 1343 is fixedly mounted on the connecting bracket 1342 at the output end of the second telescopic device 1341. The connecting bracket 1342 can slide with the guide groove 1102 provided on the mounting bracket 110 to increase stability. When the storage disc 12 needs to be separated from the spindle 112, the brake block 1343, driven by the second telescopic device 1341, can approach and abut the extension 1212, thereby braking the storage disc 12 after it is separated from the spindle 112.

[0057] It should be noted that the overall mass of the wire storage disc 12 is relatively large. After the wire storage disc 12 is separated from the main shaft 112 through the clutch mechanism 13, since the wire storage disc 12 and the main shaft 112 are rotated together through bearings, the rotational friction of the wire storage disc 12 is relatively small, and the wire storage disc 12 will continue to rotate under its own large rotational inertia. Therefore, it is necessary to set a brake assembly 134 to quickly brake the wire storage disc 12 that is separated from the main shaft 112, so as to quickly rewind the wire storage box 122 on the wire storage disc 12. In addition, in order to ensure that the brake assembly 134 brakes the wire storage disc 12 stably, the number of brake blocks 1343 can be set to multiple, for example Figure 7 As shown, there are two brake blocks 1343 , and the two brake blocks 1343 can be in frictional contact with the extension portion 1212 at the same time.

[0058] In this example, there are many specific structures of the reversing mechanism 15 that can realize the reverse rotation of the wire storage box 122. For the sake of easy understanding, the following will be described in detail using one of the structures. Figure 5 、 Figures 11 to 13 As shown, the extension 1212 is circumferentially provided with clearance slots 1213 corresponding to each wire storage box 122. These clearance slots 1213 are located closer to the disk body 121 than the contact point between the brake assembly 134 and the extension 1212, preventing interference between the reversing mechanism 15 and the brake assembly 134. A first friction wheel 1221 is coaxially mounted on at least one side of the wire storage box 122. The reversing mechanism 15 is mounted on the same side as the first friction wheel 1221 and comprises a second rotating device 151, a rotating sleeve 152, and a plurality of transmission gear trains 153 and second friction wheels 154 corresponding to the number of wire storage boxes 122. The second rotating device 151 is fixedly mounted to the wire storage disk 12, while the rotating sleeve 152 is coaxially mounted to the wire storage disk 12 and meshes with a first gear 1511 mounted on the output end of the second rotating device 151 via a rack segment 1521 mounted on its side. Each transmission gear train 153 is mounted on the wire storage disk 12 and circumferentially corresponds to a corresponding wire storage box 122. The input end of the transmission gear train 153 can pass through the clearance groove 1213 to engage with the clutch sleeve 131 or the main shaft 112, while the output end of the transmission gear train 153 can be spaced apart from the first friction wheel 1221 coaxially mounted on the corresponding wire storage box 122. The second friction wheel 154 is rotatably mounted on a rotating shaft 1541, which directly slides into a slot 1215 provided on the side of the disk body 121. The rotating shaft 1541 can also slide into the slot 1215 via a rotatably mounted slider 1542, thereby reducing wear. The slot 1215 extends in the direction perpendicular to the midline connecting the output end of the transmission gear train 153 and the first friction wheel 1221. The slider 1542 and the rotating sleeve 152 are hingedly connected by a corresponding hinge plate 1522.

[0059] When the wire storage disc 12 rotates synchronously with the main shaft 112, the second friction wheel 154 moves away from the first friction wheel 1221, so that the wire storage box 122 can rotate and unwind as the wire 220 is pulled. When the wire storage disc 12 is separated from the main shaft 112 and the wire storage box 122 needs to be reversely wound, the rotating sleeve 152 rotates under the drive of the second rotating device 151, and then the slider can drive the second friction wheel 154 to slide along the perpendicular line connecting the output end of the transmission gear train 153 and the first friction wheel 1221 under the drive of the hinge plate 1522, until the second friction wheel 154 simultaneously engages with the first friction wheel 1221 and the output end of the transmission gear train 153, thereby realizing the transmission of the transmission gear train 153 to the first friction wheel 1221 through the second friction wheel 154, and then driving the corresponding wire storage box 122 to rotate in the opposite direction to complete the winding.

[0060] It is understandable that the transmission gear train 153 includes at least one transmission wheel, and based on the requirement that the wire storage box 122 rotates in the opposite direction relative to the main shaft 112, the number of gears included in the transmission gear train 153 needs to be an odd number. This can keep the rotation direction of the output end of the transmission gear train 153 opposite to the rotation direction of the main shaft 112. Then, when the second friction wheel 154 transmits the power to the first friction wheel 1221, the first friction wheel 1221 can drive the coaxial wire storage box 122 to rotate in the opposite direction relative to the main shaft 112. The specific number of transmission wheels included in the transmission gear train 153 can be determined according to actual needs, such as one, three, or five.

[0061] It should be noted that in order to ensure that the second friction wheel 154 can simultaneously and stably cooperate with the first friction wheel 1221 and the output end of the transmission gear train 153, the size of the transmission wheel corresponding to the output end of the transmission gear train 153 needs to be the same diameter as the first friction wheel 1221. Since the wire storage box 122 is far away from the main shaft 112, if the transmission gear train 153 uses a single transmission wheel, the second friction wheel 154 needs to be large and inconvenient to install. Therefore, the transmission gear train 153 can adopt a plurality of transmission wheels. This not only reduces the size of the friction wheels and the transmission wheels, but also increases the speed ratio between the main shaft 112 and the wire storage box 122, thereby improving the winding efficiency of the wire storage box 122.

[0062] For ease of understanding, the following detailed description will be given by taking the transmission gear train 153 with three transmission wheels as an example. Assume that the input end of the transmission gear train 153 passes through the clearance groove 1213 and meshes with the outer gear teeth 1311 of the clutch sleeve 131. Figure 12 and Figure 13As shown, the three transmission wheels are a second gear 1531, a third gear 1532, and a fourth gear 1533. The fourth gear 1533 is positioned adjacent to and meshes with the clutch sleeve 131, serving as the input of the transmission gear train 153. The third gear 1532 meshes with the fourth gear 1533, while the second gear 1531 meshes with the third gear 1532. A third friction wheel of equal diameter to the first friction wheel 1221 is coaxially mounted on one side of the second gear 1531, serving as the output of the transmission gear train 153. The extending direction of the sliding groove 1215 coincides with the perpendicular midline connecting the axes of the third friction wheel and the first friction wheel 1221. Driven by the rotating sleeve 152, the second friction wheel 154 can simultaneously engage in friction with the first friction wheel 1221 and the third friction wheel.

[0063] It should be noted that when winding the wire storage box 122, depending on the installation position of the wire arranging device, winding can generally be performed simultaneously on two or more wire storage boxes 122 in symmetrical directions. Taking six wire storage boxes 122 as an example, assuming each wire arranging device only winds one wire storage box 122, during the time it takes for one wire storage box 122 to twist and pay out, the six wire storage boxes 122 on the other wire storage reel 12 to complete the winding process three times. Therefore, the speed ratio between the first friction wheel 1221 and the main shaft 112 must be at least 3. To allow for rewiring time for the wire arranging device, the speed ratio between the first friction wheel 1221 and the main shaft 112 must be at least greater than 3. Through the aforementioned transmission gear train 153, the speed ratio between the first friction wheel 1221 and the main shaft 112 is significantly greater than 3. However, the speed ratio should not be too large, as this will cause the wire storage box 122 to rotate too fast, affecting the winding quality. Generally, the speed ratio can be set between 5 and 8.

[0064] In this embodiment, there are many specific rotation installation methods for the rotating sleeve 152. For ease of understanding, the following will be described in detail using one of the structures. Figure 6 and Figure 13 As shown, a plurality of positioning wheels 1214 are provided along the circumferential direction on one side of the wire storage drum 12; the positioning wheels 1214 can be rotatably mounted or fixedly mounted, with rotatable mounting being preferred. A positioning area can be formed between the plurality of positioning wheels 1214, and the rotating sleeve 152 can be installed in the positioning area to achieve concentric rotational mounting with the wire storage drum 12. The specific number of positioning wheels 1214 can be selected according to actual needs, but in order to ensure the formation of the positioning area, the number of positioning wheels 1214 must be at least three, and the central angle corresponding to the arc length of the connecting line of the three positioning wheels 1214 along the circumferential direction must be greater than 180°, so that the rotating sleeve 152 can be kept stably mounted; for example Figure 6 As shown, the number of positioning wheels 1214 is five.

[0065] Another aspect of the present application provides a stranding machine, such as Figure 1 and Figure 2 As shown, one preferred embodiment includes at least one twisting module 1 and a winding device (not shown). The twisting module 1 can twist the wire 220 with the center line 210 to form the required cable. The winding device is used to wind the twisted cable and increase the tension required for twisting the wire 220. The specific structure of the center line 210, the wire 220 and the winding device is well known to those skilled in the art and will not be elaborated on here. The specific number of twisting modules 1 is related to the number of layers required to be twisted in the cable. The twisting module 1 includes the above-mentioned rewinding transmission structure; and a wire drum 113 is installed at the end of the main shaft 112 away from the first rotating device 111, and the wire drum 113 is provided with a plurality of wire holes 1130 spaced apart in the circumferential direction. The wire 220 extending from the wing tension control mechanism 14 can pass through the corresponding wire holes 1130 to be twisted with the center line 210 passing through the first inner hole 1120 in the center of the main shaft 112. The wire reel 113 is used to lift the wire 220 to a certain height to ensure that the wire 220 and the center line 210 can be twisted at a suitable angle.

Those skilled in the art should understand that the present application is not limited to the above-described embodiments.
