Description

Technical Field

[0001] The present invention relates to the technical field of cable production, and in particular to a wire twisting device and method for cable production. Background Art

[0002] The stranding device in cable production is an important equipment used to twist multiple conductive cores together to form a cable with specific structural and performance requirements. The design and operation of the stranding device are crucial to ensuring the quality and performance of the cable. The following are the main components of the stranding device: Wire roller: used to store single conductive cores to be twisted. The wire roller can be fixed or rotating. Select the appropriate type according to production needs; Wire stranding machine: the core part of the wire stranding device, used to twist multiple conductive cores together according to a predetermined twisting method and pitch; Cooling system: used to cool the conductive core during the twisting process to prevent deformation or damage to the wire due to heat generated by friction; Wire take-up device: used to collect the twisted cables into rolls for subsequent processing and transportation. The wire take-up device usually includes a take-up reel and a drive motor, which can adjust the take-up speed and tension.

[0014] Furthermore, a method for using a stranding device for cable production, based on the above-mentioned stranding device for cable production, comprises the following steps:

[0015] S1: First, install the wire roller wound with the wire on the rotating column. When all the wire rollers are installed, pass the wire on the wire roller through the through hole on the corresponding trigger member, and then pass the wire through the corresponding through hole of the rotating ring, and then pull several wires together and wind them on the wire-taking device;

[0016] S2: The driving device drives the installation drum to rotate, and the installation drum drives the rotating ring to rotate, so that a plurality of wires are twisted into one strand. At the same time, the installation drum drives the wire roller to rotate, so that the wire wound on the wire roller is released;

[0017] S3: As the remaining wire on the wire roller decreases, the motor drives the threaded rod to rotate, and the threaded rod drives the friction wheel to move through the adjustment cylinder, thereby changing the transmission position of the friction wheel and the round table wheel, and increasing the rotation speed of the wire roller;

[0018] S4: When the conductor tension on a certain wire roller is too large, the conductor squeezes the adjacent triggering member, and the triggering member moves toward the direction close to the mounting tube and compresses the adjacent spring, and drives the limiter to separate from the adjacent wire roller. At this time, the wire roller rotates relative to the adjacent rotating column under the action of the conductor tension on it, and then the limiter is aligned with the next adjacent limit slot on the adjacent wire roller. At this time, the triggering member, the limiter and the limit column are reset;

[0019] S5: After the wire on the wire roller is used up, press the adjacent sliding member, the sliding member transmission locking member releases the limit on the adjacent fixing member, and then rotates the fixing member to separate the fixing member from the rotating column, and replaces the wire roller. After completion, reinstall the fixing member.

[0020] Compared with the prior art, the present invention has the following advantages: the present invention makes the wire roller rotate synchronously with the installation drum to avoid the wire roller being directly pulled by the wire, thereby preventing the wire from being subjected to excessive tension and causing the diameter to change, thereby ensuring the quality of the produced cable.

[0021] By changing the transmission position of the round table wheel and the friction wheel, when the wire wound on the wire roller decreases, the rotation speed of the wire roller is increased, thereby ensuring that the wire release speed matches the twisting speed and avoiding the cable quality failing to meet the standards.

[0022] When the tension of the wire on the wire roller is too large, the adjacent limiting members release the limit between the adjacent rotating columns and the adjacent wire rollers, and then the wire rollers are rotated to release the excessive tension on the wire, thereby avoiding the diameter change or even breakage of the wire due to excessive tension.

[0023] The locking member is used to limit the adjacent fixing member and the rotating column, thereby providing further protection for the connection between the fixing member and the rotating column, and preventing the fixing member from being separated from the adjacent rotating column due to centrifugal force when the thread on the fixing member is damaged.

DETAILED DESCRIPTION

[0033] Although the present invention may be described with respect to a particular application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as left, right, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0034] Example 1: Please refer to Figure 1-Figure 4The present embodiment provides a stranding device for cable production, which is used to ensure the laying-out effect of the conductor, and includes: a driving device 1; a support frame 2 is provided on one side of the driving device 1, and the support frame 2 is rotatably connected to a rotating ring 21, and the rotating ring 21 is provided with evenly distributed through holes for the conductor to pass through; the driving device 1 is provided with a mounting cylinder 3, and the mounting cylinder 3 is fixedly connected to the rotating ring 21, and the mounting cylinder 3 is fixedly connected to a partition plate 4 distributed at intervals, and the partition plate 4 is provided with evenly distributed through holes for the conductor to pass through; a rotating column 5, which has a plurality of groups, and each group contains a plurality of evenly distributed rotating columns 5, which are used to make the mounting cylinder 3 bear force evenly, All the rotating columns 5 are rotatably connected to the mounting tube 3 and penetrate it, the rotating column 5 is threadedly connected with a fixing part 51, and the rotating column 5 is provided with a wire roller 6; the rotating rod 7 is rotatably connected in the mounting tube 3, and the plurality of rotating columns 5 and the rotating rod 7 are transmitted through a bevel gear set; the trigger member 8 has a plurality of groups, each group contains a plurality of evenly distributed trigger members 8, which are used to allow the wire to pass through in the same state, and the plurality of groups of trigger members 8 are respectively arranged on adjacent partition plates 4, and the trigger members 8 are provided with through holes, and a mounting frame 9 is provided on one side of the driving device 1; an adjusting component is arranged on the mounting frame 9, and is used to adjust the rotation speed of the rotating rod 7.

[0035] In this embodiment, the driving device 1 is an existing device, which is used to drive the installation cylinder 3 to rotate and provide support for its left side. The support frame 2 is used to provide support for the right side of the installation cylinder 3. The through holes on the rotating ring 21 are evenly distributed and used to allow the wires to pass through. The driving device 1 drives the rotating ring 21 to rotate through the installation cylinder 3. The rotating ring 21 twists a plurality of wires. Three evenly distributed support members are arranged between the driving device 1 and the support frame 2 to support the three evenly distributed partition plates 4, so as to prevent the installation cylinder 3 from sagging due to excessive weight in the middle. The rotating column 5 has a plurality of evenly distributed groups, each of which has a plurality of evenly distributed groups. The group has a plurality of rotating columns 5 evenly distributed in the circumferential direction. The side of the rotating column 5 away from the mounting cylinder 3 is threadedly connected to the fixing piece 51. The fixing piece 51 is used to fix the line roller 6 on the adjacent rotating column 5. Bearings can be installed between the line roller 6 and the mounting cylinder 3 as well as between the line roller 6 and the adjacent fixing piece 51 to reduce the resistance of the line roller 6 when it rotates with the rotating column 5. When the mounting cylinder 3 rotates, the mounting cylinder 3 and the rotating rod 7 rotate relative to each other. At this time, the rotating column 5 rotates by itself through the bevel gear group between it and the rotating rod 7, so that the line roller 6 can release the line, thereby avoiding the wire breaking caused by the wire pulling the line roller 6 to rotate.

[0036] See also Figure 4The adjusting component includes: a truncated cone wheel 10, which is rotatably connected to the mounting frame 9, a gear box 11 is fixedly connected to the driving device 1, the input shaft of the gear box 11 and the mounting cylinder 3 are transmitted through a gear ring, and the output shaft of the gear box 11 is fixedly connected to the truncated cone wheel 10; a friction wheel 12, which is splined to the rotating rod 7, and the friction wheel 12 and the truncated cone wheel 10 are frictionally matched; a power component, which is arranged on the mounting frame 9, and is used to provide the power required for adjustment to the adjusting component.

[0037] The left side of the driving device 1 is fixedly connected to the gear box 11. When the mounting cylinder 3 rotates, the input shaft of the gear box 11 is driven to rotate through the ring gear, and the output shaft of the gear box 11 drives the frustum wheel 10 to rotate. The surfaces of the frustum wheel 10 and the friction wheel 12 are both made of friction materials for transmission therebetween. The frustum wheel 10 drives the friction wheel 12 to rotate through friction, and the friction wheel 12 drives the rotating rod 7 to rotate.

[0038] See also Figure 4 The generatrix of the frustum wheel 10 close to the friction wheel 12 is parallel to the moving direction of the friction wheel 12 , so as to enable the friction wheel 12 and the frustum wheel 10 to transmit at different diameters.

[0039] When the friction wheel 12 moves, the friction wheel 12 always keeps in contact with the frustum wheel 10 and transmits power.

[0040] See also Figure 4 and Figure 5 The power assembly includes: an adjusting cylinder 13, which is splined to the mounting frame 9, the adjusting cylinder 13 is rotatably connected to the friction wheel 12, the mounting frame 9 is rotatably connected to a threaded rod 14, the threaded rod 14 is threadedly matched with the adjusting cylinder 13, the mounting frame 9 is fixedly connected to a motor 15, and the output shaft of the motor 15 is fixedly connected to the threaded rod 14.

[0041] The adjusting cylinder 13 and the threaded rod 14 cooperate to adjust the position of the friction wheel 12, and the motor 15 drives the threaded rod 14 to rotate. The threaded rod 14 moves the adjusting cylinder 13 to the right through the thread, thereby adjusting the rotation speed of the wire roller 6. When the wire on the wire roller 6 gradually decreases, the rotation speed of the wire roller 6 increases, thereby ensuring that the wire-releasing speed of the wire roller 6 remains unchanged, so that the wire-releasing speed of the wire roller 6 matches the twisting speed of the cable. The motor 15 can also be replaced by other transmission mechanisms, such as driving the threaded rod 14 to rotate through a gearbox to drive the mounting cylinder 3.

[0042] See also Figure 6 , also includes: a limit piece 16, having a plurality of them, the rotating column 5 is provided with first slide grooves 501 evenly distributed in the circumferential direction, the number of the limit pieces 16 corresponds to the number of the rotating columns 5, and the plurality of limit pieces 16 are respectively slidably connected to adjacent first slide grooves 501, and the line roller 6 is provided with limit grooves evenly distributed in the circumferential direction, and the limit pieces 16 are limitedly matched with adjacent limit grooves on adjacent line rollers 6.

[0043] Each rotating column 5 is provided with a plurality of first slide grooves 501 uniformly distributed in the circumferential direction, so that the limit member 16 can limit the adjacent line roller 6 again without having to rotate a full circle. The limit member 16 is composed of a round rod and a wedge block. The round rod portion of the limit member 16 is slidably connected to the adjacent first slide groove 501, and the lower side of the wedge block portion of the limit member 16 is provided with an inclined surface. When the line roller 6 is installed, the line roller 6 squeezes the limit member 16 on the adjacent rotating column 5, so that the limit member 16 moves. When the rotating column 5 rotates, the adjacent line rollers 6 are driven to rotate through the plurality of limit members 16.

[0044] See also Figure 3 and Figure 6 The partition plate 4 is provided with evenly distributed second slide grooves 401, the number of the second slide grooves 401 corresponds to the number of the trigger members 8, the second slide grooves 401 are slidably connected to the trigger member 8, the trigger member 8 is slidably connected to the partition plate 4, a spring is provided between the trigger member 8 and the adjacent partition plate 4, the mounting cylinder 3 is provided with a plurality of connecting grooves 301, the number of the connecting grooves 301 corresponds to the number of the rotating columns 5, the connecting grooves 301 are connected to the adjacent second slide grooves 401 through a hose, the plurality of first slide grooves 501 on the same rotating column 5 are all connected to the adjacent connecting grooves 301, and the connecting grooves 301, the second slide grooves 401 and the first slide grooves 501 are all filled with liquid.

[0045] The spring between the trigger member 8 and the adjacent partition plate 4 is initially in a compressed state, which is used to make preliminary adjustments to the wire of the adjacent trigger member 8. The liquids mentioned above and below are all hydraulic oils, which are used to transmit between the wire roller 6 and the adjacent trigger member 8. When the tension of the wire is too large, the pressure of the wire on the adjacent trigger member 8 increases, and the trigger member 8 moves toward the direction close to the mounting tube 3 and compresses the adjacent spring, thereby sucking the liquid in the adjacent first slide groove 501 into the adjacent second slide groove 401 through the adjacent connecting groove 301 and the adjacent hose, so that the corresponding several limit members 16 are separated from the adjacent wire roller 6. At this time, the wire roller 6 rotates relative to the adjacent rotating column 5 under the action of the wire tension thereon, thereby releasing the tension on the wire roller 6. A lubricant can be arranged between the rotating column 5 and the wire roller 6 to reduce the friction between the rotating column 5 and the wire roller 6. Thereafter, the limit member 16 is aligned with the next adjacent limit groove of the adjacent wire roller 6. At this time, the trigger member 8 loses the extrusion and resets under the action of the adjacent spring.

[0046] See also Figure 3 , and also includes: a limit column 17, which has a plurality of limit columns 17, and the plurality of limit columns 17 are respectively slidably connected to adjacent trigger members 8, a spring is arranged between the limit column 17 and the adjacent trigger member 8, and the partition plate 4 is provided with a plurality of grooves, and the limit column 17 is limitedly matched with the adjacent grooves on the adjacent partition plate 4.

[0047] The limiting column 17 is composed of a cylinder and a hemisphere. The spring adjacent to the limiting column 17 is initially in a compressed state, so that the limiting column 17 provides resistance for the trigger member 8. When the trigger member 8 moves, it drives the adjacent limiting column 17 to move. The limiting column 17 is squeezed by the adjacent partition plate 4 to move and compress the adjacent spring.

[0048] See also Figure 3 , Figure 7 and Figure 8 , also includes: a limit assembly, having a plurality of limit assemblies, which are respectively arranged on adjacent fixing members 51, and are used to fix adjacent fixing members 51 and adjacent rotating columns 5, the limit assembly includes: a sliding member 18, the sliding member 18 is slidably connected to the adjacent fixing member 51, a spring is arranged between the sliding member 18 and the fixing member 51, the sliding member 18 is fixedly connected to an extrusion member 19, the extrusion member 19 is provided with circumferentially distributed inclined grooves, the fixing member 51 is slidably connected to a circumferentially distributed locking member 20, the locking member 20 is extruded and matched with the adjacent inclined grooves on the adjacent extrusion member 19, and the locking member 20 is limitedly matched with the adjacent rotating column 5.

[0049] The sliding member 18 is composed of a round rod and a disc. A spring is arranged between the side of the disc portion of the sliding member 18 close to the mounting tube 3 and the adjacent fixing member 51. The spring is initially in a compressed state and is used to maintain the limiting state of the locking member 20 between the adjacent fixing member 51 and the adjacent rotating column 5. After the wire on the wire roller 6 is used up, the adjacent sliding member 18 is pressed. The sliding member 18 compresses the adjacent spring and drives the adjacent extruding member 19 to move. The extruding member 19 squeezes the adjacent locking member 20 to release the limiting of the adjacent fixing member 51. Then, the fixing member 51 is rotated to separate the fixing member 51 from the rotating column 5, and the wire roller 6 is replaced. After completion, the fixing member 51 is reinstalled.

[0050] See also Figure 8 The side of the inclined groove on the extrusion member 19 close to the mounting cylinder 3 is far away from the axis of the adjacent sliding member 18, and the side of the inclined groove on the extrusion member 19 away from the mounting cylinder 3 is close to the axis of the adjacent sliding member 18.

[0051] When the installation cylinder 3 drives the rotating column 5 to rotate, the rotating column 5 drives the fixing part 51 to rotate, and the fixing part 51 drives the extruding part 19 and the sliding part 18 to rotate. Under the action of centrifugal force, the two tend to move toward the side away from the installation cylinder 3. Even if the spring between the sliding part 18 and the adjacent fixing part 51 is damaged, the sliding part 18 and the extruding part 19 will continue to squeeze the adjacent locking part 20, thereby preventing the fixing part 51 from falling off.

[0052] When using the device, first install the wire roller 6 wound with the wire on the rotating column 5, then rotate the fixing member 51 to fix the wire roller 6. When all the wire rollers 6 are installed, pass the wire on the wire roller 6 through the through hole on the corresponding trigger member 8, and then pass the wire through the corresponding through hole of the rotating ring 21. Then, pull and wind several wires together on the wire-taking device. In this process, the driving device 1 drives the installation cylinder 3 to rotate, and the installation cylinder 3 drives the rotating ring 21 to rotate, so that several wires are twisted into one strand. At the same time, the installation cylinder 3 drives the round table through the gear box 11. The wheel 10 rotates, and the truncated cone wheel 10 drives the rotating rod 7 to rotate through the friction wheel 12. The rotating rod 7 drives the rotating columns 5 to rotate through several bevel gear sets. The rotating columns 5 drive the adjacent wire rollers 6 to rotate through several adjacent limit members 16, thereby releasing the wire wound on the wire roller 6. As the remaining wire on the wire roller 6 decreases, the motor 15 drives the threaded rod 14 to rotate. The threaded rod 14 pushes the adjusting cylinder 13 to move to the right through the thread. The adjusting cylinder 13 pushes the friction wheel 12 to move, thereby changing the transmission position of the friction wheel 12 and the truncated cone wheel 10 and increasing the rotation speed of the wire roller 6.

[0053] When the wire tension on a certain wire roller 6 is too large, the wire squeezes the adjacent trigger member 8, and the trigger member 8 moves toward the direction close to the mounting tube 3 and compresses the adjacent spring. The trigger member 8 drives the adjacent limit column 17 to move. The limit column 17 is squeezed by the adjacent partition plate 4 to move and compress the adjacent spring. At the same time, the liquid in the adjacent first slide groove 501 is sucked into the adjacent second slide groove 401 through the adjacent connecting groove 301 and the adjacent hose, so that the corresponding several limit members 16 are separated from the adjacent wire roller 6. At this time, the wire roller 6 rotates relative to the adjacent rotating column 5 under the action of the wire tension thereon, thereby releasing the tension on the wire roller 6, and then the limit member 16 is aligned with the next adjacent limit groove on the adjacent wire roller 6. At this time, the trigger member 8 loses the extrusion and resets under the action of the adjacent spring. After the trigger member 8 is reset, the partition plate 4 is also reset. At the same time, the trigger member 8 drives the limit member 16 to reset, so that the rotating column 5 drives the adjacent wire roller 6 to rotate again through the limit member 16.

[0054] After the wire on the wire roller 6 is used up, the adjacent sliding member 18 is pressed, and the sliding member 18 compresses the adjacent spring and drives the adjacent extruding member 19 to move. The extruding member 19 squeezes the adjacent locking member 20 to release the limit on the adjacent fixing member 51, and then the fixing member 51 is rotated to separate the fixing member 51 from the rotating column 5, and the wire roller 6 is replaced. After completion, the fixing member 51 is reinstalled.

[0057] S2: the driving device 1 drives the installation cylinder 3 to rotate, and the installation cylinder 3 drives the rotating ring 21 to rotate, so that a plurality of wires are twisted into one strand. At the same time, the installation cylinder 3 drives the wire roller 6 to rotate, so that the wire wound on the wire roller 6 is released;

[0058] S3: As the remaining wire on the wire roller 6 decreases, the motor 15 drives the threaded rod 14 to rotate, and the threaded rod 14 drives the friction wheel 12 to move through the adjustment cylinder 13, thereby changing the transmission position of the friction wheel 12 and the round table wheel 10, and increasing the rotation speed of the wire roller 6;

[0059] S4: When the wire tension on a certain wire roller 6 is too large, the wire squeezes the adjacent trigger member 8, and the trigger member 8 moves toward the direction close to the mounting tube 3 and compresses the adjacent spring, and drives the limit member 16 to separate from the adjacent wire roller 6. At this time, the wire roller 6 rotates relative to the adjacent rotating column 5 under the action of the wire tension on it, and then the limit member 16 is aligned with the next adjacent limit groove on the adjacent wire roller 6. At this time, the trigger member 8, the limit member 16 and the limit column 17 are reset;

[0060] S5: After the wire on the wire roller 6 is used up, the adjacent sliding member 18 is pressed, and the sliding member 18 drives the locking member 20 to release the limit on the adjacent fixing member 51. Then the fixing member 51 is rotated to separate the fixing member 51 from the rotating column 5, and the wire roller 6 is replaced. After completion, the fixing member 51 is reinstalled.
