Description

Technical Field

[0001] The present application relates to the technical field of wire stranding equipment, and in particular to a concentric cable stranding machine. Background Art

[0002] The concentric stranding machine is a non-back-twisting stranding machine. It mainly installs multiple pairs of storage drums on the main shaft at intervals. A flying wing tension controller is installed between the two storage drums of each pair to control the tension of the cable. Multiple wires are rewound into the storage drum at the same time, and after the rewinding is completed, they also need to be released through the flying wing at the same time.

[0003] However, when the existing concentric stranding machine is re-winding after stranding, it is often necessary to stop the machine first and then rewind the wire storage drum before continuing to work. Although it is not necessary to load and unload the drum, it still needs to stop the machine. The time required for rewinding the stranding machine is generally relatively long, which will affect the production efficiency of the stranding machine. Summary of the invention

DETAILED DESCRIPTION

[0037] 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.

[0038] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and cannot be understood as limiting the specific scope of protection of the present application.

[0039] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0040] The terms "including" and "having" and any variations thereof in the specification and claims of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0041] One of the preferred embodiments of the present application is as follows: Figures 1 to 3 As shown, a concentric cable twisting machine includes at least one twisting module 1 and a winding device 300; the twisting module 1 can twist the conductors 220 and the center line 210 to form the required cable 200. The winding device 300 is used to wind up the twisted cable 200 and increase the tension required for twisting the conductors 220. The specific structures of the center line 210, the conductors 220 and the winding device 300 are well known to those skilled in the art, so they will not be elaborated here in detail. The specific number of twisting modules 1 is related to the number of layers required to be twisted in the cable 200; a specific example, such as Figure 1 As shown, the cable 200 needs to be twisted in three layers, so the number of twisting modules 1 is three and they are arranged sequentially from front to back, and the winding device 300 is separated from the last twisting module 1. The center line 210 can pass through all the twisting modules 1, and the twisting modules 1 twist the first to third layers of conductors 220 on the center line 210 in order from front to back, so as to obtain the required cable 200. For easy understanding, the specific structure will be described below through one of the twisting modules 1.

[0042] In this embodiment, Figures 2 to 4As shown, the twisting module 1 includes a frame 100, a transmission mechanism 11, at least one pair of wire storage drums 12 and at least one wing tension control mechanism 14. 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 connected to the main shaft 112 through the output end, so that the main shaft 112 is driven by the first rotating device 111 to rotate. There are many transmission structures between the first rotating device 111 and the main shaft 112, and the common ones 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 the transmission structure of the main shaft 112 is preferably a belt transmission. The specific structure and working principle of the first rotating device 111 are well-known technologies for those skilled in the art. The common one is a motor, and the specific power can be selected according to actual needs. The wing tension control mechanism 14 and the wire storage drum 12 are both installed on the main shaft 112; wherein, the wing tension control mechanism 14 is fixedly installed on the main shaft 112 and is located between a corresponding pair of wire storage drums 12; the wire storage drum 12 can be installed on the main shaft 112 through a corresponding clutch mechanism 13. During the continuous twisting operation of the twisting module 1, the wire storage drum 12 can rotate synchronously with the main shaft 112 and pay out the wire to the wing tension control mechanism 14, and the two wire storage drums 12 of each pair 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 release, 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 shut down, and then the stranding machine can be restarted to continue working. Compared with the traditional shutdown winding method, the present application can greatly shorten the downtime of the stranding machine, thereby effectively improving the working efficiency of the stranding machine.

[0043] It is understandable that the working mode of the traditional twisting machine is: twisting - stopping - winding - connection - twisting; and after adopting the technical solution of the present application, the working mode of the twisting machine is: twisting (synchronous winding) - stopping - connection - twisting (synchronous winding). Compared with the traditional method, the present application can reduce the time of a winding process, thereby effectively shortening the downtime of the twisting machine to improve the production efficiency of the twisting machine.

[0044] It should be known that the specific number of wire storage drums 12 is related to the number of wires 220 required for twisting the cable 200. If the number of wires 220 required for single-layer twisting of the cable 200 is large, and the number of wires 220 released on one wire storage drum 12 cannot meet the number of wires 220 required for single-layer twisting, multiple wire storage drums 12 need to be set to maintain the number of wires 220. Correspondingly, multiple wing tension control mechanisms 14 also need to be set; and the wire storage drums 12 of this embodiment are used in pairs, so the number of pairs required for the wire storage drums 12 can be determined according to the number of wires 220 required for single-layer twisting of the cable 200.

[0045] 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 5 to 11 As shown, the main shaft 112 is provided with an outer gear ring 1121 at the corresponding installation position of the storage disk 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 meshes with the outer gear ring 1121 on the main shaft 112 through the inner gear 1312 arranged on the inner side to form an axial spline connection, so that the clutch sleeve 131 can rotate synchronously with the main shaft 112 and can also reciprocate along the axial direction of the main shaft 112. The storage disk 12 is rotatably mounted on the main shaft 112 through the second inner hole 1210 in the center; at the same time, the second inner hole 1210 can also mesh with the outer gear 1311 arranged on the outer side of the clutch sleeve 131 through the inner gear ring 1211 arranged on the side wall to form 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 and cooperates with the wire storage drum 12 .

[0046] When the storage drum 12 is performing the line-releasing operation, the clutch sleeve 131 maintains the meshing 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 line-releasing. When the storage drum 12 has completed all the line-releasing 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 which 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 line-releasing state. Then, the brake assembly 134 can be used to brake the storage drum 12 that is separated from the main shaft 112, so that the storage drum 12 in the disengaged state can be reversely rotated to achieve rewinding.

[0047] 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.

[0048] Specifically, there are many specific structures of the traction assembly 133 that can achieve the above functions. For the sake of easy understanding, one of the structures will be described in detail below. Figures 7 to 11 As 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 and the clutch sleeve 131 are at the same height. 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 matched 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 a 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.

[0049] 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 5 , Figure 7 and Fig.11 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 disk 12. The guide rods 1313 can slide through the baffle 1123 on the main shaft 112, and the first springs 132 are sleeved on the guide rods 1313, and the two ends of the first spring 132 are respectively against the baffle 1123 and the end surface of the clutch sleeve 131, thereby realizing the elastic sliding installation of the clutch sleeve 131 and the main shaft 112.

[0050] 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 7As shown in the figure, the connecting end of the traction frame 1332 is in a "U" shape, so that the traction frame 1332 can be hinged to the hinge rod arranged at the upper and lower limit height positions of the connecting sleeve 1331, thereby ensuring that when the traction frame 1332 rotates, it drives the upper and lower ends of the connecting sleeve 1331 simultaneously 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 fitted through bearings or balls, so that the sliding friction becomes rolling friction to reduce wear.

[0051] 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 in a strip shape, so that when 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.

[0052] 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 first spring 132 to realize the reconnection 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 first spring 132 is sufficient, the first spring 132 can be made of rectangular elasticity. 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 adopt a cylinder or a hydraulic cylinder.

[0053] 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.

[0054] Initially, if Figure 8 and Fig.11 As shown in (1), at this time, the clutch sleeve 131 is meshed with the inner gear ring 1211 of the storage disk 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 maintain connection with 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 first spring 132 can be in a natural state or in an elastic deformation state.

[0055] When the wire storage drum 12 needs to be separated from the main shaft 112, Fig. 9 and Fig.11 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 traction groove 1334 away from the clutch sleeve 131, and then the traction plate 1335 and the traction groove 1334 are abutted against each other 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 first spring 132 is in an elastically compressed state.

[0056] When the wire storage drum 12 has finished rewinding and is ready to be connected to the main shaft 112 again, as shown in FIG. Fig.10As shown, the first telescopic device 1336 can drive the traction plate 1335 to contract, so that the traction plate 1335 can slide along the traction groove 1334 to one end close to the clutch sleeve 131. In this process, if the outer gear 1311 and the inner gear ring 1211 are exactly corresponding, the clutch sleeve 131 can be reset to the meshing state of the outer gear 1311 and the inner gear ring 1211 under the elastic force of the first 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 clutch sleeve 131, until the wire storage disk 12 and the main shaft 112 rotate relatively to the outer gear teeth 1311 and the inner gear ring 1211 just correspond to each other, and the clutch sleeve 131 can be reset to the meshing state of the outer gear teeth 1311 and the inner gear ring 1211 under the elastic force of the first spring 132, and the first telescopic device 1336 can also be reset to the initial position. Generally speaking, in the process that the first telescopic device 1336 drives the traction plate 1335 to move along the traction groove 1334 from one end away from the clutch sleeve 131 to the end close to the clutch sleeve 131, the wire storage disk 12 and the main shaft 112 have performed a relative movement at a certain angle. In 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 first spring 132, and the reset drive of the first telescopic device 1336 can ensure that the clutch sleeve 131 can be reset to the initial position.

[0057] Those skilled in the art should know that for different application scenarios, the winding method of the wire storage drum 12 is different; when the number of wires 220 required for single-layer twisting of the cable 200 is small, the wire storage drum 12 can be directly wound through the drum body 121; when the number of wires 220 required for single-layer twisting of the cable 200 is large, multiple wire storage boxes 122 can be set on the drum body 121 of the wire storage drum 12, and each wire storage box 122 is wound. For different application scenarios, a detailed description will be given below through specific examples.

[0058] Example 1: A scenario in which the wire storage reel 12 is directly wound through the reel body 121 .

[0059] The specific structure of the disc body 121 is well known in the art, and mainly includes a winding post and a circular wire baffle plate at both ends of the winding post. The wire storage disc 12 can be rotated with the main shaft 112 through the winding post, and the diameter of the wire baffle plate is greater than the diameter of the winding post. For the above scenario, the brake assembly 134 includes a second telescopic device 1341 and a rotating device. The second telescopic device 1341 is fixedly installed on the frame 100, and the rotating device is installed at the output end of the second telescopic device 1341, so that the rotating device can approach and fit the side of the wire baffle plate of the wire storage disc 12 and perform friction cooperation under the drive of the second telescopic device 1341. Through the friction cooperation between the rotating device and the wire storage disc 12, the wire storage disc 12 can be braked to a standstill first, and then after the wire arrangement device and the wire storage disc 12 are connected to complete the winding, the rotating device can be started to drive the wire storage disc 12 to rotate in the opposite direction until the wire storage disc 12 is braked to a standstill again after the winding is completed, and finally the wire arrangement device can be separated from the wire storage disc 12.

[0060] It should be known that the specific structure of the wire arrangement device is a well-known technology for those skilled in the art. The wire arrangement device is mainly used for winding the wire storage disk 12. While releasing the wire to the wire storage disk 12, it can drive the wire 220 to be wound to move back and forth along the axial direction of the wire storage disk 12 to ensure that the wire 220 can be evenly wound around the winding column of the wire storage disk 12. The specific structure and working principle of the second telescopic device 1341 and the rotating device are well-known technologies for those skilled in the art. The common second telescopic device 1341 is a cylinder or a hydraulic cylinder, and the common rotating device is a motor. The motor can be frictionally matched with the side of the wire baffle of the wire storage disk 12 through the friction wheel installed at the output end.

[0061] Example 2: A scenario in which a plurality of wire storage boxes 122 are arranged along the circumferential direction of the wire storage tray 121 .

[0062] like Figure 2 , Figure 3 and Figure 6 As shown, a plurality of wire storage boxes 122 can be correspondingly mounted on the disk body 121 and can release wires at corresponding positions to the wing tension control mechanism 14 under the guidance of the first guide wheel 123 provided on the disk body 121. When the wire storage disk 12 is separated from the main shaft 112, the brake assembly 134 can brake the wire storage disk 12 separated from the main shaft 112. The stranding module 1 also includes a reversing mechanism 15 installed on the wire storage disk 12. The reversing mechanism 15 can drive the main shaft 112 and the wire storage box 122 after the wire storage disk 12 is separated from the main shaft 112, so that the wire storage box 122 can be reversely rotated relative to the stationary wire storage disk 12 to complete the rewinding.

[0063] It should be understood that the specific number of wire storage boxes 122 can be determined according to the number of wires 220 actually required for twisting; 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 a plurality of wires 220 .

[0064] Specifically, Figures 6 to 10 As shown, at least one side of the disc body 121 is provided with an annular extension portion 1212, and the extension portion 1212 is concentric with the second inner hole 1210 of the disc body 121. The brake assembly 134 can be installed on the mounting frame 110 on the frame 100, so that the brake assembly 134 and the extension portion 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 installed on the mounting frame 110, and the brake block 1343 is fixedly installed on the connecting frame 1342 at the output end of the second telescopic device 1341. The connecting frame 1342 can be slidably matched with the guide groove 1102 provided on the mounting frame 110 to increase stability. When the storage disc 12 needs to be separated from the main shaft 112, the brake block 1343 can be driven by the second telescopic device 1341 to approach and fit the extension portion 1212, thereby braking the storage disc 12 separated from the main shaft 112.

[0065] It should be known that the overall mass of the wire storage disk 12 is relatively large. After the wire storage disk 12 is separated from the main shaft 112 through the clutch mechanism 13, since the wire storage disk 12 and the main shaft 112 are rotationally matched through bearings, the rotational friction of the wire storage disk 12 is relatively small, and the wire storage disk 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 disk 12 that is separated from the main shaft 112, so as to quickly rewind the wire storage box 122 on the wire storage disk 12. In addition, in order to ensure that the brake assembly 134 brakes the wire storage disk 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.

[0066] In this example, there are multiple 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 6 , Fig.12 and Fig.13As shown, the extension part 1212 is provided with a clearance groove 1213 corresponding to each wire storage box 122 along the circumferential direction, and the clearance groove 1213 is closer to the disk body 121 relative to the contact position between the brake assembly 134 and the extension part 1212, so as to avoid interference between the reversing mechanism 15 and the brake assembly 134. A first friction wheel 1221 is coaxially installed on at least one side of the wire storage box 122. The reversing mechanism 15 is installed on the same side as the first friction wheel 1221, and the reversing mechanism 15 includes a second rotating device 151, a rotating sleeve 152, and a plurality of transmission gear trains 153 and a plurality of second friction wheels 154 corresponding to the number of the wire storage boxes 122. The second rotating device 151 is fixedly installed on the wire storage disk 12, and the rotating sleeve 152 is coaxially installed on the wire storage disk 12 and meshes with the first gear 1511 installed on the output end of the second rotating device 151 through the rack segment 1521 arranged on the side. Each transmission gear train 153 is installed on the wire storage disk 12 and corresponds to each wire storage box 122 along the circumferential direction; the input end of the transmission gear train 153 can be meshed with the clutch sleeve 131 or the main shaft 112 through the air avoidance groove 1213, and the output end of the transmission gear train 153 can be spaced from the first friction wheel 1221 coaxially installed with the corresponding wire storage box 122. The second friction wheel 154 is rotatably installed on a slider (not shown), and the slider can be slidably installed on the first slide groove 1215 set on the side of the disk body 121. The extension direction of the first slide groove 1215 coincides with the direction of the perpendicular midline of the line connecting the output end of the transmission gear train 153 and the first friction wheel 1221; the slider and the rotating sleeve 152 are hinged through the corresponding hinge plate 1522.

[0067] When the wire storage disc 12 rotates synchronously with the main shaft 112, the second friction wheel 154 is away from the first friction wheel 1221, so that the wire storage box 122 can rotate and release the wire 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 of the 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 is frictionally matched with the first friction wheel 1221 and the output end of the transmission gear train 153 at the same time, so as to realize the transmission of the transmission gear train 153 to the first friction wheel 1221 through the second friction wheel 154, and then the corresponding wire storage box 122 can be driven to rotate in the opposite direction to complete the winding.

[0068] It can be understood that the transmission gear train 153 includes at least one transmission wheel, and according to the reverse rotation requirement of the wire storage box 122 relative to the main shaft 112, the number of gears included in the transmission gear train 153 needs to be an odd number, so that the rotation direction of the output end of the transmission gear train 153 can be kept opposite to the rotation direction of the main shaft 112, and then when the second friction wheel 154 is transmitted 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, five, etc.

[0069] It should be known that in order to ensure that the second friction wheel 154 can be stably matched with the first friction wheel 1221 and the output end of the transmission gear train 153 at the same time, the size of the transmission wheel corresponding to the output end of the transmission gear train 153 needs to be equal in diameter to 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 adopts one transmission wheel, the size of the second friction wheel 154 is large, which is inconvenient to install; therefore, the transmission gear train 153 can adopt a plurality of transmission wheels, which can not only reduce the size of the friction wheel and the transmission wheel, but also increase the speed ratio between the main shaft 112 and the wire storage box 122, so as to speed up the winding efficiency of the wire storage box 122.

[0070] For ease of understanding, the transmission gear train 153 using three transmission wheels is used as an example for detailed description. 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. Fig.12 and Fig.13 As shown, the three transmission wheels are the second gear 1531, the third gear 1532 and the fourth gear 1533; the fourth gear 1533 is close to the clutch sleeve 131 and meshes with it to serve as the input end of the transmission gear train 153, the third gear 1532 meshes with the fourth gear 1533, the second gear 1531 meshes with the third gear 1532, and a third friction wheel with the same diameter as the first friction wheel 1221 is coaxially mounted on one side of the second gear 1531 to serve as the output end of the transmission gear train 153, and the extension direction of the first slide slot 1215 coincides with the perpendicular midline of the axis connecting the third friction wheel and the first friction wheel 1221. The second friction wheel 154 can be frictionally matched with the first friction wheel 1221 and the third friction wheel at the same time under the drive of the rotating sleeve 152.

[0071] It should be noted that when winding the wire storage box 122, according to the installation position of the wire arrangement device, generally, winding can be performed on two or more wire storage boxes 122 in a symmetrical direction at the same time; taking six wire storage boxes 122 as an example, assuming that each wire arrangement device only winds one wire storage box 122, then during the twisting and unwinding working time of one wire storage box 122, the six wire storage boxes 122 on another wire storage disk 12 need to be wound three times to complete all the winding. Then the speed increase ratio between the first friction wheel 1221 and the main shaft 112 must be at least equal to 3, and in order to leave time for the re-wiring of the wire arrangement device, the speed increase ratio between the first friction wheel 1221 and the main shaft 112 must be at least greater than 3. Through the above-mentioned transmission gear train 153, the speed increase ratio between the first friction wheel 1221 and the main shaft 112 will be much greater than 3; but the speed increase ratio should not be too large, as an excessively large speed increase ratio will cause the speed of the wire storage box 122 to be too fast and affect the winding quality. Generally speaking, the speed increase ratio can be set at about 5 to 8.

[0072] In this example, there are many specific rotation installation methods for the rotating sleeve 152. For ease of understanding, a detailed description will be given below using one of the structures. Figure 6 and Fig.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 installed or fixedly installed, and rotatably installed is 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 realize concentric rotation installation 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 is 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 installed; for example Figure 6 As shown, the number of positioning wheels 1214 is five.

[0073] In this embodiment, Figure 2 , Figure 3 , Figure 5 , Fig.14 and Fig.15As shown, a wire reel 113 is installed at one end of the main shaft 112 away from the first rotating device 111, and the wire reel 113 is provided with a plurality of wire holes 1130 at intervals along the circumferential direction. The wire 220 extending from the wing tension control mechanism 14 can pass through the corresponding wire hole 1130 and be twisted with the center line 210 passing through the first inner hole 1120 at 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. The main shaft 112 is provided with a plurality of through grooves 1122 along the circumferential direction at the installation position of the wing tension control mechanism 14, and the through grooves 1122 can connect the first inner hole 1120 at the center of the main shaft 112 with the outside world. The wing tension control mechanism 14 includes a wheel body 141 and a plurality of tension control components 142. The wheel body 141 is fixedly mounted on the main shaft 112. The wheel body 141 is provided with a plurality of guide portions 1410 extending radially inwardly along the circumferential direction. The guide portions 1410 can pass through the through slots 1122 to extend into the first inner hole 1120 of the main shaft 112, so that the wire 220 released from the storage drum 12 can extend to the wire drum 113 through the guide portions 1410 inside the main shaft 112. The tension control assembly 142 is installed at equal intervals along the circumferential direction on the side of the wheel body 141, and the tension control assembly 142 can tension the wire 220 released from the storage drum 12.

[0074] It should be known that the number and position of the guide part 1410, the tension control assembly 142 and the wire storage box 122 correspond to each other. In order to ensure that the guide part 1410 guides the wire 220 smoothly, a second guide wheel 1411 can be installed in the guide part 1410, and the wire 220 passing through the tension control assembly 142 can extend in the guide part 1410 through the second guide wheel 1411 toward the wire reel 113. By routing the wire 220 from the inside of the main shaft 112, the twisting safety of the wire 220 can be ensured; that is, if the wire 220 breaks during the twisting process, the broken wire 220 will only jump inside the main shaft 112, and will not cause safety hazards to external staff.

[0075] In this embodiment, there are multiple specific structures of the tension control component 142 that can achieve tensioning of the wire 220. For ease of understanding, one of the structures will be described in detail below. Fig.14 , Figures 16 to 18As shown, the tension control assembly 142 includes a support frame 1421, a third guide wheel 1422, a tension wheel 1423 and an elastic assembly 143. The support frame 1421 is fixedly mounted on the wheel body 141, and the third guide wheel 1422 is rotatably mounted on the top of the support frame 1421. The tension wheel 1423 is rotatably mounted on a sliding seat (not shown), and the sliding seat is slidably mounted with a second slide groove 1420 horizontally arranged on the support frame 1421. The wire 220 released from the wire storage tray 12 can pass through the third guide wheel 1422 and the tension wheel 1423 in sequence and extend to the guide portion 1410. The elastic assembly 143 cooperates with the sliding seat, and the elastic assembly 143 can drive the tension wheel 1423 to move when the tension of the wire 220 changes to keep the wire 220 taut.

[0076] It should be known that in order to ensure that the tension wheel 1423 can stably tension the wire 220, the third guide wheel 1422 needs to deviate from the tension wheel 1423 in the horizontal direction. Figure 3 , Figure 4 and Fig.17 The two wire storage trays 12 can be arranged according to Figure 3 The third guide wheel 1422 can deviate from the tension wheel 1423 to the left side of the storage drum 12, and the tension of the tension wheel 1423 by the elastic component 143 is directed to the right. Figure 3 and Fig.17 As shown, the wire 220 released by the storage drum 12 can pass through the upper part of the third guide wheel 1422 and the tension wheel 1423 to extend to the guide portion 1410. When the right storage drum 12 is performing the wire release operation, as shown in FIG. Figure 4 As shown, the wire 220 can pass through the third guide wheel 1422 from the top and then extend from the bottom to the tension wheel 1423 until it reaches the guide part 1410.

[0077] In this embodiment, there are multiple specific structures of the elastic component 143. For ease of understanding, one of the structures will be described in detail below. Fig.16 and Fig.17As shown, the elastic component 143 includes a pull rope 1431, a slide bar 1432, a first elastic member and a second elastic member. The slide bar 1432 is installed on the support frame 1421 in a flush sliding manner along the moving direction of the tension wheel 1423, and the first elastic member is installed on the slide bar 1432, so that the slide bar 1432 and the support frame 1421 are elastically slidably connected. One end of the second elastic member is hinged to the support frame 1421, and the other end is connected to the slide bar 1432 through the pull rope 1431. The angle between the extension direction of the second elastic member and the axial direction of the slide bar 1432 is 90°~150°; the pull rope 1431 can pull the tension wheel 1423 after passing through the traction wheel 1424 provided on the sliding seat, so that the tension wheel 1423 slides along the second slide groove 1420 under the traction of the pull rope 1431 to achieve tensioning of the wire 220, and the traction wheel 1424 can facilitate the sliding traction of the pull rope 1431.

[0078] It should be known that there are many specific structures of the first elastic member and the second elastic member, and the common ones are shrapnel and spring. In this embodiment, the spring will be used as an example for detailed description, and the first elastic member is the second spring 1433, and the second elastic member is the third spring 1434. The second spring 1433 can be sleeved on the slide bar 1432, one end of the third spring 1434 is hinged to the support frame 1421 through the connected hinge seat 1436, and the other end of the third spring 1434 is connected to the pull rope 1431 through the connecting block 1435. The third spring 1434 can be arranged above the tension wheel 1423, or it can be arranged below the tension wheel 1423; if the third spring 1434 is arranged above the tension wheel 1423, the slide bar 1432 will be flush with the lower part of the traction wheel 1424; if the third spring 1434 is arranged below the tension wheel 1423, the slide bar 1432 will be flush with the upper part of the traction wheel 1424. For ease of understanding, this embodiment takes the example in which the third spring 1434 is disposed below the tension wheel 1423 .

[0079] It is understandable that the hinge point between the third spring 1434 and the support frame 1421 can be marked as A, and the connection point between the second spring 1433 and the rear end of the slide rod 1432 can be marked as B. Then, during the movement of the tension wheel 1423, the entire elastic component 143 can be represented by the change in the length of the line between points A and B to indicate the degree of deformation. When the tension of the wire 220 changes, for example, the tension decreases; Fig.17 As shown, assuming that the traction wheel 1424 moves to the right by a distance of X, the length change of the line between points A and B will be less than X, which makes the elastic component 143 of this embodiment have a larger tension adaptation stroke compared with the traditional single spring structure. In order to ensure the stability of the force of the tension wheel 1423, the elastic components 143 can be set at the rotation installation positions at both ends of the tension wheel 1423.

[0080] In this embodiment, Fig.18 As shown, the support frame 1421 is fixedly mounted with a clamping block 1425 at the same height as the tension wheel 1423. When the tension wheel 1423 moves to the extreme position, it can collide with the clamping block 1425, thereby clamping the loose wire 220 between the tension wheel 1423 and the clamping block 1425, so as to facilitate the subsequent wiring when the wire storage disk 12 is alternated, and at the same time, it can also clamp and protect the wire 220 from sudden breakage, so as to prevent the wire 220 from flying out and causing harm.

[0081] It should be known that when the wire storage drum 12 completes the winding, there will be no contact between the wire 220 and the wire storage drum 12. At this time, the wire 220 will be in a relaxed state, and the tension wheel 1423 can slide away from the third guide wheel 1422, or in other words, slide towards the clamp block 1425 under the drive of the elastic component 143 until the tension wheel 1423 and the clamp block 1425 are against each other. This process is relatively fast, so the end of the wire 220 that maintains the release trend can be quickly clamped to facilitate the subsequent rewiring when the wire storage drum 12 is replaced. At the same time, when the wire 220 suddenly breaks, the pressure of the wire 220 on the tension wheel 1423 will suddenly disappear. At this time, the tension wheel 1423 can also quickly approach the clamp block 1425 and clamp the broken wire 220 under the elastic force of the elastic component 143.

[0082] It should also be known that the wiring of the conductor 220 can be a continued twisting of the cable 200; or the end of the conductor 220 of the previous wire storage reel 12 can be pulled to the head end of the conductor 220 of the new wire storage reel 12, so that the conductor 220 of the new wire storage reel 12 can quickly pass through the inside of the main shaft 112 to the position of the conductor reel 113, without the need for manual threading from the main shaft 112 again.

[0083] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
