Description

Technical Field

[0001] The present application relates to the technical field of stranding equipment, and in particular to a rewinding and unwinding infinite adjustment mechanism and a stranding machine. Background Art

[0002] A concentric stranding machine is a non-backtwist stranding machine. It features multiple pairs of accumulators spaced apart on the main shaft. A wing tension controller is installed between each pair of accumulators to control cable tension. Multiple wires are simultaneously rewound onto the accumulators and then released simultaneously through the wing after rewinding.

[0003] However, when existing concentric stranding machines need to be shut down before rewinding after stranding, the machine must first be shut down and the wire storage reel must be rewound before continuing to work. Although the reel does not need to be loaded and unloaded, the machine still needs to be shut down. The time required for rewinding the stranding machine is generally quite long, which will affect the production efficiency of the stranding machine. Utility Model Content

DETAILED DESCRIPTION

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] One 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. Twisting module 1 can twist conductors 220 onto a centerline 210 to form the desired cable. The specific twisting method is well known to those skilled in the art and will not be elaborated on here. Specifically, twisting module 1 includes a transmission mechanism 11, a frame 100, a wing tension control mechanism 14, and an infinitely adjustable rewinding and payout mechanism. Transmission mechanism 11 includes a main shaft 112 and a first rotating device 111. Main shaft 112 is rotatably mounted on frame 100. First rotating device 111 is fixedly mounted on frame 100 and is in transmission connection with main shaft 112 via an output end, allowing main shaft 112 to rotate under the drive of first rotating device 111. Various transmission structures can be used between first rotating device 111 and main shaft 112, with gear drives, belt drives, and chain drives being common. Due to the relatively high overall weight of twisting module 1, rigid starting of main shaft 112 is unsuitable. Therefore, a belt drive is preferably used as the transmission structure for main shaft 112. The specific structure and operating principle of the first rotating device 111 are well known to those skilled in the art. A motor is typically used, and the specific power can be selected based on actual needs. The wing tension control mechanism 14 is fixedly mounted on the main shaft 112. It tensions the wire 220 released by the infinitely adjustable rewinding and payout mechanism. The infinitely adjustable rewinding and payout mechanism pays out wire to the wing tension control mechanism 14 in a manner that allows for infinite payout.

[0036] Another aspect of the present application provides a rewinding and unwinding infinite adjustment mechanism for the stranding machine, such as Figures 1 to 3 As shown, one preferred embodiment includes a pair of accumulators 12 and a pair of clutch mechanisms 13. The accumulators 12 can be mounted on the main shaft 112 via corresponding clutch mechanisms 13, and the two accumulators 12 can be mounted on the front and rear sides of the wing tension control mechanism 14 along the axial direction of the main shaft 112. During the continuous twisting operation of the twisting module 1, the accumulators 12 can rotate synchronously with the main shaft 112 and pay out the wire to the wing tension control mechanism 14, and the two accumulators 12 in each pair can pay out the wire alternately.

[0037] When one of the wire storage drums 12 is unwinding, it means that the other wire storage drum 12 has completed all the unwinding. At this time, the other wire storage drum 12 can be driven by the clutch mechanism 13 to decouple from the synchronous rotation of 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 unwinding, 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, and can basically realize unlimited unwinding and stranding of the stranding machine to improve the working efficiency of the stranding machine.

[0038] It is understandable that the working mode of the traditional twisting machine is: twisting - stopping - winding - wiring - twisting; and after adopting the technical solution of the present application, the working mode of the twisting machine is: twisting (synchronous winding) - stopping - wiring - twisting (synchronous winding). Compared with the traditional method, the present application can reduce the time of one winding process; generally speaking, the time required for the winding process is relatively long, and the time for stopping for wiring is extremely short compared to the winding process. Therefore, for the twisting work of the twisting machine, it is only necessary to stop and replace it with another wire storage disk 12 when one wire storage disk 12 completes the wire unwinding. In this way, the twisting machine can basically achieve unlimited wire unwinding during the twisting process, thereby effectively improving the production efficiency of the twisting machine.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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 6As 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.

[0044] 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.

[0045] In this embodiment, there are many specific structures of the traction assembly 133. For the sake of easy understanding, one of the structures will be described in detail below. Figures 6 to 10 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 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.

[0046] It should be noted that there are various specific elastic sliding installation methods for the clutch sleeve 131; for the convenience of understanding, one specific example is as follows Figure 4 , Figure 6 and Figure 10 As shown, a radially extending baffle 1123 is provided on the main shaft 112. A plurality of guide rods 1313 are arranged at equal intervals in the circumferential direction on the end face of the clutch sleeve 131 away from the wire storage disc 12, such as four guide rods 1313. The guide rods 1313 can slide through the baffle 1123 on the main shaft 112, and springs 132 are sleeved on the guide rods 1313. The two ends of the springs 132 respectively abut against the baffle 1123 and the end face of the clutch sleeve 131, thereby realizing the elastic sliding installation of the clutch sleeve 131 and the main shaft 112.

[0047] In order to ensure the traction stability of the clutch sleeve 131, there are at least two hinge points between the traction frame 1332 and the connecting sleeve 1331, and the connecting lines of the multiple hinge points can intersect at the center point of the connecting sleeve 1331. For example Figure 6 As 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 rods 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 when rotating to improve the traction stability. 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.

[0048] It should also be noted 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.

[0049] It is understood that since the clutch sleeve 131 meshes with the inner gear ring 1211 of the inner hole of the storage drum 12 via the outer gear 1311, when the clutch sleeve 131 needs to be re-connected to the storage drum 12, the gear teeth and clearance between the outer gear 1311 and the inner gear ring 1211 may not correspond, which may interfere with the resetting 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 hingedly connected via a strip-shaped traction groove 1334. When the teeth and clearance between the outer gear teeth 1311 and the inner gear ring 1211 do not match, the first telescopic device 1336 can be reset to a position close to its initial position by sliding the traction plate 1335 relative to the traction groove 1334. Then, as the main shaft 112 rotates relative to the storage drum 12, the teeth and clearance between the outer gear teeth 1311 and the inner gear ring 1211 match. The clutch sleeve 131 can be reset under the elastic force of the spring 132 to reconnect the clutch sleeve 131 with the storage drum 12. At this time, the traction frame 1332 rotates about the support pin 1101, and the traction plate 1335 can slide along the traction groove 1334 again to avoid interference. To ensure sufficient elasticity of the spring 132, the spring 132 can be a rectangular spring. The specific structure and operating principle of the first telescopic device 1336 are well known to those skilled in the art and will not be elaborated here. Common first telescopic devices 1336 can be pneumatic or hydraulic cylinders.

[0050] 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.

[0051] 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.

[0052] When the wire storage drum 12 needs to be separated from the main shaft 112, as shown in FIG. Figure 8 and Figure 10As 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.

[0053] When the accumulator 12 has finished rewinding and is ready to be connected to the spindle 112 again, as shown in FIG. Figure 9 As 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.

[0054] In this embodiment, Figure 11 and Figure 12As shown, the infinitely adjustable rewinding and payout mechanism also includes a reversing mechanism 16 mounted on the frame 100. This mechanism 16 can engage in frictional transmission with the accumulator drum 12, which is detached from the spindle 112, thereby driving the accumulator drum 12 to reverse winding. Specifically, when the accumulator drum 12 is paying out the wire, the reversing mechanism 16 can move away from the accumulator drum 12 to ensure that its rotation is not interfered with. When the accumulator drum 12 is detached from the spindle 112 and rewinding is performed, the reversing mechanism 16 can move closer to the accumulator drum 12 and engage in frictional transmission.

[0055] Specifically, there are many specific structures of the reversing mechanism 16 that can achieve the above functions. For the sake of easy understanding, one of the structures will be described in detail below. Figure 11 and Figure 12 As shown, the reversing mechanism 16 includes a third telescopic device 161 and a second rotating device 162. The third telescopic device 161 is fixedly mounted on the frame 100 and is connected to the second rotating device 162 via an output end. Driven by the third telescopic device 161, the second rotating device 162 can approach the wire storage drum 12 that is disconnected from the main shaft 112 through friction engagement at the output end, thereby driving the wire storage drum 12 to rotate in the opposite direction.

[0056] It should be noted that the specific structure and working principle of the third telescopic device 161 and the second rotating device 162 are well known to those skilled in the art and will not be elaborated in detail here. Common third telescopic device 161 is a cylinder or a hydraulic cylinder, and common second rotating device 162 is a motor.

[0057] Those skilled in the art will appreciate that the winding method of the wire storage drum 12 varies for different application scenarios. When the number of wires 220 required for a single-layer twisted cable 200 is small, the wire storage drum 12 can be used to directly wind the wires through the drum body 121. When the number of wires 220 required for a single-layer twisted cable 200 is large, multiple wire storage boxes 122 can be provided on the drum body 121 of the wire storage drum 12, with each wire storage box 122 being used for winding. The following describes different application scenarios in detail using 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 disk body 121 is well known in the art, and mainly includes a winding post and circular wire baffles located at both ends of the winding post. The wire storage disk 12 can be rotated with the main shaft 112 through the winding post, and the diameter of the wire baffle is larger than the diameter of the winding post. For the above scenario, there are many ways to cooperate with the reversing mechanism 16. For ease of understanding, two ways will be described below. Method 1: The second rotating device 162 can be driven by the third telescopic device 161 to frictionally cooperate with the edge of the wire baffle of the disk body 121 through the second friction wheel installed at the output end. Method 2: As Figure 11 As shown, the second rotating device 162 can be driven by the third telescopic device 161 to frictionally cooperate with the extension part 1212 installed on the side end of the disk body 121 through the second friction wheel installed at the output end; it should be noted that when the second rotating device 162 cooperates with the extension part 1212 through the second friction wheel, the brake block 1343 of the brake assembly 134 needs to maintain a distance from the extension part 1212.

[0060] Example 2: A scenario in which a plurality of wire storage boxes 122 are arranged along the circumference of the wire storage reel 121 .

[0061] like Figure 6 and Figure 12 As shown, multiple wire storage boxes 122 can be rotatably mounted on the disk body 121 and, guided by the guide wheel 123 mounted on the disk body 121, release wire to corresponding positions toward the wing tension control mechanism 14. When the wire storage disk 12 is disengaged from the main shaft 112, the brake assembly 134 can brake the wire storage disk 12 that has separated from the main shaft 112. After the wire storage disk 12 is separated from the main shaft 112, the reversing mechanism 15 can sequentially connect to each wire storage box 122 through friction transmission, allowing multiple wire storage boxes 122 to perform reverse winding. Because the wire baffles on the sides of the wire storage boxes 122 are relatively thin, friction transmission is not convenient. Therefore, a first friction wheel 1221 is coaxially mounted at one end of each wire storage box 122. The reversing mechanism 16 then uses a second friction wheel mounted on the output end of the second rotating device 162 to approach and release the first friction wheel 1221, driving the wire storage boxes 122 to rotate in the opposite direction to achieve winding.

[0062] It should be understood that the specific number of the wire storage boxes 122 can be determined based on 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 multiple wires 220 .

[0063] It is understood that the winding can be performed using a wire arranging device. The specific structure of the wire arranging device is well known to those skilled in the art. The wire arranging device is primarily used for winding the wire storage reel 12 or the wire storage box 122. While releasing the wire into the wire storage reel 12 or the wire storage box 122, the wire arranging device can drive the wire 220 to be wound to move back and forth along the axial direction of the wire storage reel 12 or the wire storage box 122 to ensure that the wire 220 can be evenly wound around the winding post of the wire storage reel 12 or the wire storage box 122. For Example 2, since the two diagonally located wire storage boxes 122 are 180° symmetrical, the wire arranging device can be installed on both sides of the main shaft 112, so that Example 2 only requires three windings. Based on the number of times the wire storage box 12 is wound, the reverse rotation speed of the wire storage box 12 must be at least three times the speed of the main shaft 112. This ensures that the wire storage disk 12 that has detached from the main shaft 112 can complete rewinding within the working time of another wire storage disk 12. However, the speed of the wire storage box 12 should not be too fast. Generally speaking, the rewinding speed of the wire storage disk 12 is five times the speed of the main shaft 112. Because the disk body 121 and the main shaft 112 are matched with bearings, the disk body 121 can be manually driven to rotate a set angle during the multiple winding processes of the wire storage box 122.

[0064] In this embodiment, Figure 1 and Figure 2 As shown, a wire reel 113 is mounted on the end of the main shaft 112 away from the first rotating device 111. The wire reel 113 has a plurality of wire holes 1130 spaced apart along the circumference. 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 extending through the first inner hole 1120 in the center of the main shaft 112. The wire reel 113 is used to raise the wire 220 to a certain height to ensure that the wire 220 and the center line 210 are twisted at a suitable angle.
