Description

Technical Field

[0001] The present invention relates to the technical field of cable coiling, and particularly relates to a coiling mechanism and a usage method for cable production. Background Art

[0002] During the cable production process, multiple conductors or multiple groups of wire cores are coiled around a stranding reel at a certain angle and in a certain manner to form a certain winding structure. This winding method helps with convenient storage, transportation, and subsequent connection.

[0003] According to the patent publication number CN119541955B, publication date: April 25, 2025, there is disclosed a cable stranding machine, including a base plate, on which a motor, a wire guiding frame, a wire dividing wheel, a lead wheel, and a combining die are provided. The output shaft of the motor is fixedly installed with a rotating shaft, which respectively passes through the wire guiding frame, the wire dividing wheel, and the lead wheel. A cable is provided on the wire guiding frame, and the cable respectively passes through the wire dividing wheel and the lead wheel and is stranded into a cable in the combining die. A through hole is provided in the wire dividing wheel, and a first connecting frame and a second connecting frame are respectively provided in the through hole. A fixed wheel is provided below the first connecting frame, and a movable wheel is provided above the second connecting frame. The cable is located between the fixed wheel and the movable wheel.

[0004] In the prior art including the above patent, the reverse limiting mechanism can be triggered by the instantaneous reverse rotation of the fixed wheel to block the cable from splashing out of the wire dividing wheel, avoid the cable from winding around the machine due to the huge rebound force after breaking, and prevent injury to the staff. However, in actual operation, especially in the stranding production of cross-linked polyethylene insulated power cables, the rotation of the coiling equipment is used to complete the stranding production of the cable. Most coiling mechanisms in actual use can only achieve the guiding and restraint of the cable, or use the equipment in the above patent to provide a certain protection for the cable to avoid injury to the staff. When the cable is stranded through the coiling mechanism, due to the uneven tension of the cable, the cable is prone to problems such as loose stranding or excessive tension during stranding, resulting in uneven stranding or even breakage. Therefore, the regulation of the cable tension in cable production helps to improve the stable production and safety of the cable. Summary of the Invention

[0020] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] As Figures 1 - 13 shown, a disc twisting mechanism for cable production includes a wiring disc 2 and a conductor disc 14 arranged in sequence along the axial direction of a winding tube 1. A plurality of copper wire discs 4 arranged in a circular array are movably installed on the wiring disc 2. The center of the copper wire disc 4 is coaxial with a wire passing groove 16 opened on the conductor disc 14, and a feedback frame 3 is rotatably arranged in the wire passing groove 16; A pressure roller 34 is provided below the first end of the feedback frame 3, and a deflector roller 37 is provided above the second end. The copper wire on the copper wire reel 4 passes through the feedback frame 3. When the deflector roller 37 rotates in a predetermined direction, it picks up the copper wire, and the pressure roller 34 presses down the copper wire.

[0022] Specifically, a wire bundling reel 11 is sleeved on the winding tube 1. The wire bridging reel 2, the wire guiding reel 14, and the wire bundling reel 11 are respectively fixedly installed on the winding tube 1 by bolts. The winding tube 1 includes a front frame 12 and a rear frame 13, and the winding tube 1 is rotatably arranged on the front frame 12 and the rear frame 13. An extension plate 33 is fixedly welded to the first end of the feedback frame 3, and the pressure roller 34 is rotatably arranged on the extension plate 33. A wire passing opening 39 is formed on the feedback frame 3, and limiting rods 35 are symmetrically and rotatably arranged below the feedback frame 3. An adjusting roller 36 is rotatably arranged above the feedback frame 3 between the pressure roller 34 and the deflector roller 37. The copper wire reel 4 is rotatably arranged on the wire bridging reel 2, and the copper wire on the copper wire reel 4 is arranged below the pressure roller 34. Then, the copper wire passes between the two limiting rods 35 and through the wire passing opening 39, and then is arranged above the adjusting roller 36 and above the deflector roller 37. The copper wire passing through the deflector roller 37 then is arranged along the wire bundling reel 11 and the front frame 12. The winding tube 1 is driven electrically to rotate in a predetermined direction, and the pulling of the subsequent production equipment drives the copper wire to perform a stranding operation. During the stranding process of the copper wire, the copper wire passing through the deflector roller 37 and the pressure roller 34 is tightened due to pulling. When the tension of the copper wire pulled out from the copper wire reel 4 decreases, the feedback frame 3 rotates to press the first end of the feedback frame 3 against the copper wire, and the second end of the feedback frame 3 picks up the copper wire, so as to adjust the state of the copper wire to make the copper wire in a tightened state again, thus avoiding the problem that the overly loose copper wire affects the stranding quality of the copper wire. When the tension of the copper wire increases, the feedback frame 3 rotates to swing up the first end of the feedback frame 3 and swing down the second end of the feedback frame 3, so as to reduce the short-time pressing on the copper wire to reduce its tension, thus avoiding the problem that the copper wire is overly tightened in a short time and is prone to breakage, thereby improving the stability of the equipment operation.

[0023] For the swing and pressure feedback of the feedback frame 3, a hydraulic cylinder and a pressure sensor can be used. The hydraulic cylinder is fixedly installed on the wire guiding reel 14, and a pressure sensor is installed at the output end of the hydraulic cylinder. The output end of the hydraulic cylinder is located at the downward turning of the second end of the feedback frame 3. When the tension of the copper wire increases, it deflects the second end of the feedback frame 3 to turn downward, and thus the pressure value of the pressure sensor increases. By collecting and timely processing the pressure value of the pressure sensor, and then cooperating with the corresponding control circuit board, the output distance of the hydraulic cylinder is controlled to make the tension degree of the copper wire on the feedback frame 3 at a suitable value. For the information acquisition of the control circuit board, the data acquisition and processing of the pressure sensor are well-known technical means in the art and will not be elaborated here.

[0024] The feedback frame 3 is made of an aluminum alloy frame.

[0025] In the above technical solution, the copper wire is arranged below the pressure roller 34 and above the pull roller 37 after passing through the feedback frame 3. Therefore, when the copper wire is twisted and tightened, under the force of the feedback frame 3, when the tension of the copper wire decreases, the pressure roller 34 presses down the copper wire and the pull roller 37 lifts up the copper wire, thereby changing the state of the copper wire and increasing the tension of the copper wire in a short time. When the copper wire is over-tensioned, the pressure roller 34 moves up and the pull roller 37 moves down to reduce the tension of the copper wire, thereby changing the state of the copper wire again and reducing the tension of the copper wire in a short time. The feedback frame 3 is swung to adjust the tension of the copper wire, thereby improving the twisting quality of the copper wire in the twisting production of cross-linked polyethylene insulated power cables.

[0026] As an embodiment further provided by the present invention, a buffer kit consisting of a sleeve 91 and a cushion 9 sliding in the sleeve 91 is provided on the second end of the feedback frame 3 on the wire reel 14, and when the roller 37 picks up the copper wire, the cushion 9 compresses the main spring 92 provided on the cushion 9 to deform.

[0027] Specifically, a ring edge 15 is fixedly welded to the side of the wire reel 14 , and the sleeve 91 is fixedly welded to the inner wall of the ring edge 15 , and one end of the main spring 92 is fixedly mounted on the ring edge 15 .

[0028] Furthermore, when the twisted copper wire is tightened by the twisting, the copper wire is located between the roller 37 and the cushion 9. When the tension of the copper wire decreases, the roller 37 turns up and the pressure roller 34 turns down, so that the roller 37 turns up and pushes the copper wire to approach the cushion 9. At this time, the cushion 9 is pushed by the copper wire to slide in the sleeve 91. At the same time, the main spring 92 deforms and accumulates force. When the corresponding copper wire pushes the cushion 9, the copper wire is subjected to a reverse downward thrust, and then under the pushing action of the cushion 9, the copper wire can be tightened to increase the tension of the copper wire, and then the cushion 9 and the main spring 92 cooperate to effectively buffer and enhance the tension when the tension of the copper wire is increased.

[0029] As another embodiment provided by the present invention, when the second end of the feedback frame 3 swings up to the maximum angle, the distance between the roller 37 and the guide roller 93 rotatably arranged on the cushion 9 is the shortest.

[0030] Specifically, the axis of the pull roller 37 is parallel to the axis of the guide roller 93. When the tension of the copper wire pulled out from the copper wire reel 4 decreases, the feedback frame 3 is rotated to make the first end of the feedback frame 3 further press down on the copper wire and increase the tension of the copper wire, while the second end of the feedback frame 3 lifts up the copper wire to make the copper wire close to the cushion 9, and under the obstruction of the cushion 9, the deformation and tension of the copper wire are further increased to improve the tensioning effect.

[0031] When the copper wire on the copper wire reel 4 breaks, the dialing roller 37 is swung to the maximum angle at this time, so that the copper wire is further dialed closer to the cushioning member 9. At this time, the copper wire is squeezed between the cushioning member 9 and the dialing roller 37 to limit and fix the copper wire to a certain extent. Therefore, when the copper wire on the copper wire reel 4 breaks, by stopping the rotation of the pipe winding 1 and swinging the dialing roller 37 to the maximum angle, the copper wire can be clamped and have a certain fixing effect, which is convenient for subsequent crimping and connecting the terminal to the copper wire. This can reduce the large-range displacement caused by the breakage and pulling of the copper wire due to stranding, as well as the influence of the loosening of the copper wire caused by the displacement of the broken copper wire on the stranded cable.

[0032] As another embodiment provided by the present invention, the feedback frame 3 rotates in the wire passing groove 16 through the fixedly installed main shaft 38. The short arm of the feedback frame 3 is on one side of the dialing roller 37, and the long arm of the feedback frame 3 is on one side of the pressing roller 34.

[0033] Specifically, the long arm and the short arm on the feedback frame 3 form a lever relative to the main shaft 38. As the long arm end of the feedback frame 3, it presses on the copper wire due to the gravity of the feedback frame 3 itself. Then, when the copper wire is stranded, due to the gravity of the feedback frame 3 itself and the tension of the copper wire, the copper wire located below the pressing roller 34 is pressed to produce a certain arc, and the long arm of the feedback frame 3 is at a certain downward inclination angle under the normal tension of the copper wire.

[0034] Furthermore, when the tension of the copper wire decreases, the downward bending degree of the pressing roller 34 on the copper wire increases, and the inclination angle of the downward swing of the pressing roller 34 increases. At this time, the dialing roller 37 and the pressing roller 34 move synchronously to swing upward, so that the dialing roller 37 dials the copper wire closer to the cushioning member 9. Under the squeezing and twisting between the dialing roller 37 and the cushioning member 9, the tension of the copper wire is increased and the resistance increases when the copper wire is pulled, so that the copper wire can be in a suitable tension intensity. When the tension of the copper wire increases, the copper wire will push the pressing roller 34 upward at this time. Then, the downward pressure of the pressing roller 34 can counteract the sudden tension or sudden increase in the tension of the copper wire in a short time. When the pressing roller 34 moves upward, the dialing roller 37 and the pressing roller 34 move synchronously to swing downward again at this time, so that the copper wire gradually moves away from the cushioning member 9 and reduces the influence of the pushing of the main spring 92 on the cushioning member 9 on the tension of the copper wire, so that the tension of the copper wire is relieved or reduced, so that the copper wire is in a suitable tension degree.

[0035] Furthermore, since the long arm and the short arm on the feedback frame 3 form a lever effect relative to the main shaft 38, when the pressure roller 34 on the long arm swings down, the thrust of the upward swing of the roller 37 increases, so that when the copper wire breaks or the copper wire on the copper wire reel 4 is used up, the roller 37 can better push the copper wire close to the cushion 9 and improve the clamping strength of the roller 37 and the cushion 9 on the copper wire. In order to enhance the clamping effect, an anti-sliding block can be provided on one side of the roller 37 on the feedback frame 3, so that when the roller 37 swings to the maximum angle, the cushion 9 pushes the copper wire close to the rubber anti-sliding block to enhance the limiting and fixing effect of the copper wire.

[0036] As another embodiment provided by the present invention, it also includes a pressing platform 6 fixedly installed on the outer wall of the wire pick-up drum 2 and located between the wire pick-up drum 2 and the wire drum 14, and a pad 61 located on the downward swing path of the pressure roller 34 is hingedly provided on the pressing platform 6, and when the pressure roller 34 swings down to the maximum angle, it covers the copper wire on the pad 61.

[0037] Specifically, Figure 5 , Figure 11 and Figure 12 As shown, a positioning spring 64 is fixedly installed between the pad 61 and the press platform 6, and a first pole piece 63 is fixedly installed on the pad 61, and second pole pieces 62 arranged in a circular array are fixedly installed on the press platform 6. In the default state, the positioning spring 64 pushes the pad 61 to make the first pole piece 63 and the two second pole pieces 62 at its two ends fit together. Then, the pad 61 is pushed to the default state by multiple positioning springs 64, so that the multiple second pole pieces 62 are in a series state under the connection action of the first pole piece 63. Therefore, by connecting the corresponding circuit sensor to the circuit on one of the second pole pieces 62 or the first pole piece 63, by energizing the second pole piece 62 and the first pole piece 63 connected in series, and detecting whether the energized current is in a normally open state, the winding tube 1 is started to coil the copper wire. When the copper wire on one of the copper wire reels 4 is used up and detached from the copper wire reel 4, the tension of the copper wire decreases rapidly. Due to the decrease in the tension of the copper wire, the pressure roller 34 presses the copper wire down and swings down, and then drives the copper wire to move onto the pad 61. The pad 61 is flipped close to the pressing table 6 due to the push of the pressure roller 34. When the pad 61 flips close to the pressing table 6, at this time, Figure 12 As shown, the second pole piece 62 is disconnected from the first pole piece 63, and the positioning spring 64 is deformed and stored by the flipping and squeezing of the pad 61. The series circuit is then placed in an open circuit state, and the information collected by the detection circuit sensor is used to coordinate with the corresponding relay and other switching devices to control the motor on the winding tube 1 to shut down, thereby achieving timely stop control and facilitating the subsequent staff to replace the new copper wire drum 4. Similarly, when the copper wire on the copper wire drum 4 breaks, the tension of the copper wire caused by the copper wire breaking drops rapidly, so that the pressure roller 34 can also flip the pad 61 to stop the rotation of the winding tube 1.

[0038] Therefore, by detecting the tension of the copper wire by the pressing roller 34 and the swinging of the pressing roller 34, it is convenient to stop the pipe winding 1 in time to reduce the influence on the subsequent stranding of the copper wire. When the pressing roller 34 presses on the backing plate 61, the upper swing angle of the deflector roller 37 is the largest at this time. Therefore, by the limiting clamping of the copper wire by the pressing roller 34 and the backing plate 61 and the limiting clamping of the copper wire by the deflector roller 37 and the cushioning member 9, the limiting and certain fixing effect on the copper wire is improved.

[0039] The use of circuit sensors, signal detection, and the switching control between relays and motors are well-known technical means to those skilled in the art and will not be elaborated here.

[0040] As the optimal embodiment provided by the present invention, an installation frame group arranged in a circular array is fixedly installed on the wire connecting disc 2, and the installation frame group includes main installation frames 21 that are symmetrically arranged and located on opposite sides of the copper wire disc 4. Plug-ins 8 that are in plug-in fit with the copper wire disc 4 are respectively slidably arranged on the two main installation frames 21, wherein: The two plug-ins 8 move relative to each other.

[0041] Specifically, the main installation frame 21 is fixedly welded to the wire connecting disc 2. A receiving cavity 24 is formed on the outer wall of the adjacent side of the two main installation frames 21 in the installation frame group, and the plug-in 8 slides in the receiving cavity 24. Rubber limiting blocks 86 are respectively fixedly bonded to the outer walls of the adjacent sides of the two plug-ins 8 by glue.

[0042] By making the two plug-ins 8 be received in the receiving cavity 24 in the default state, and then placing the copper wire disc 4 between the two main installation frames 21, and coordinating the synchronous movement of the two plug-ins 8 to approach the copper wire disc 4 so that the two plug-ins 8 are inserted into the disc holes on the copper wire disc 4. At this time, the copper wire disc 4 is limited on the two plug-ins 8. At this time, the friction between the plug-in 8 and the copper wire disc 4 is reduced by the rotating ball 82 on the plug-in 8. And through the plugging limit of the two plug-ins 8, it is convenient to install and limit the copper wire disc 4. When the copper wire on the copper wire disc 4 is used up and needs to be replaced, at this time, the two plug-ins 8 are driven to retract into the receiving cavity 24 again, and the rubber limiting blocks 86 extend out of the outer wall of the main installation frame 21, so that the copper wire disc 4 is detached from the plug-in 8. And under the limit of the two rubber limiting blocks 86, the copper wire disc 4 is prevented from falling off. Then, by manual pulling, the copper wire disc 4 is detached from the rubber limiting blocks 86, so as to facilitate the rapid replacement of the copper wire disc 4 by manual.

[0043] Furthermore, the sliding mode of the two plug-ins 8 can be respectively pushed by an electric push rod; or respectively pushed by a motor cooperating with a lead screw and a nut for sliding; or any other way of driving the two plug-ins 8 to slide that is well-known to those skilled in the art is also acceptable.

[0044] As yet another embodiment provided by the present invention, a compression sleeve 7 is slidably arranged on the plug-in member 8. After the compression sleeve 7 and the plug-in member 8 are synchronously moved to a predetermined distance, the plug-in member 8 is blocked and retained, and the compression sleeve 7 moves relative to the plug-in member 8. A plurality of elastic pieces 73 fixedly installed on the compression sleeve 7 are deformed by being extruded by the plug-in member 8 and then approach and abut against the copper wire coil 4.

[0045] Specifically, the compression sleeve 7 is slidably arranged on an insertion tube 84 fixedly welded on the plug-in member 8, and an extrusion spring 85 is fixedly installed between the compression sleeve 7 and the plug-in member 8. A plurality of extension rods 83 are fixedly welded on the plug-in member 8, and a plurality of guide rods 72 fixedly welded on the outer wall of the compression sleeve 7 are respectively slidably arranged on the extension rods 83. The extension rods 83 are slidably arranged in a slideway 23 opened on the inner wall of the accommodation cavity 24. A plurality of elastic pieces 73 are respectively fixedly welded on the compression sleeve 7, and the elastic pieces 73 are respectively movably arranged in grooves 81 opened on the plug-in member 8.

[0046] Further, by sliding the compression sleeve 7, at this time, under the action of the extrusion spring 85, the plug-in member 8 is driven to move synchronously, so that the plug-in member 8 can be inserted into the copper wire coil 4 between the two main mounting brackets 21. Then, when the extension rod 83 slides to one end of the slideway 23, at this time, the plug-in member 8 is blocked and retained. Then, continue to slide the compression sleeve 7. At this time, the compression sleeve 7 slides on the insertion tube 84 to approach the plug-in member 8. Under the blocking of the groove wall of the groove 81 and being extruded and deformed, the plurality of elastic pieces 73 respectively approach and abut against the inner wall of the hole of the copper wire coil 4. Furthermore, by controlling the distance between the compression sleeve 7 and the plug-in member 8, the fitting and extrusion degree between the elastic pieces 73 and the inner wall of the hole of the copper wire coil 4 is controlled. Furthermore, by using the fitting and extrusion of the plurality of elastic pieces 73 against the inner wall of the hole of the copper wire coil 4, the friction between the elastic pieces 73 and the copper wire coil 4 is used to increase the resistance of the copper wire coil 4 to rotate. And the increase in the rotation resistance of the copper wire coil 4 will increase the tension of the copper wire being twisted and pulled. Therefore, by controlling the fitting and extrusion degree between the elastic pieces 73 and the copper wire coil 4, it is convenient to adjust the tension of the copper wire twisting of the copper wire coil 4.

[0047] The compression sleeves 7 on the two main mounting brackets 21 can be slid respectively by the pushing of an electric push rod; or respectively by the sliding push of a motor cooperating with a lead screw and a nut; or any other way known to those skilled in the art to drive the two plug-in members 8 to slide is acceptable.

[0048] As yet another embodiment provided by the present invention, it further includes a swing frame 5, on which swing rings 53 symmetrically and fixedly arranged respectively rotate on the main mounting brackets 21, and a dial rod 54 fixedly installed on the swing ring 53 slides on a protrusion 71 arranged at the first end of the compression sleeve 7.

[0049] Specifically, a swing groove 22 is provided on the main mounting frame 21, and the swing rings 53 fixedly welded on both ends of the swing frame 5 are respectively located in the swing grooves 22 on the two main mounting frames 21, and the swing rings 53 are rotated on the main mounting frame 21 through the side shafts 55 fixedly welded thereon, and a plug spring 74 is fixedly installed between the extension rod 83 and the main mounting frame 21, and the protrusion 71 includes a high position and a low position. When the swing frame 5 is flipped from the vertical state to the horizontal state, the levers 54 on the two swing rings 53 move along the low position of the protrusion 71 to the high position. The pressing sleeve 7 moves, and the lever 54 pushes and squeezes the protrusion 71 to make the pressing sleeve 7 slide, and then in the process of the pressing sleeve 7 sliding, the two plug-ins 8 can be plugged into the copper wire drum 4 to install the limited copper wire drum 4, and in the process of the swing frame 5 swinging downward from the horizontal, the plug-in 8 is blocked and retained, and the pressing sleeve 7 continues to slide so that the multiple spring pieces 73 are respectively close to and abut against the inner wall of the copper wire drum 4, so as to adjust the resistance of the copper wire drum 4 when it rotates by controlling the downward flipping angle of the swing frame 5, and then adjust the tension of the copper wire on the copper wire drum 4.

[0050] The swing frame 5 can be rotated by pushing with an electric push rod, or by driving with a motor, or by any other method known to those skilled in the art to drive the swing frame 5 to rotate.

[0051] As a further optimal embodiment of the present invention, when the pressure roller 34 and the swing frame 5 move synchronously and swing down, the lever 54 of the swing frame 5 slides on the protrusion 71.

[0052] Specifically, a torsion spring 56 is sleeved on the side shaft 55, and the two ends of the torsion spring 56 are fixedly mounted on the side shaft 55 and the main mounting frame 21, respectively. A symmetrically opened slot 51 is provided on the swing frame 5, and an opening 52 is provided on the slot wall of the symmetrically opened slot 51. A seesaw 31 is fixedly mounted on the first end of the feedback frame 3, and a long roller 32 is symmetrically rotated and arranged on the seesaw 31. The swing frame 5 is flipped to switch from a vertical state to a horizontal state. At this time, the swing frame 5 is rotated to make the lever 54 move from the low position to the high position along the protrusion 71 and squeeze the pressing sleeve 7 to slide, and then the two plug-ins 8 are plugged into the copper wire drum 4 to install the limit copper wire drum 4. At this time, the swing frame 5 is further lowered to facilitate the long roller 32 on the seesaw 31 to slide into the slot 51 along the opening 52, so that the swing frame 5 and the feedback frame 3 are connected, and the torsion spring 56 is in a state of deformation and force storage. Then, the copper wire on the copper wire drum 4 is arranged along the bottom of the pressure roller 34 and the top of the pull roller 37. Then, during the copper wire twisting process, the pressure roller 34 is moved due to the tension of the copper wire. In the normal twisting state of the copper wire, the swing frame 5 is in a horizontal state, and the first end of the feedback frame 3 is tilted downward. When the tension of the copper wire decreases, the deadweight of the feedback frame 3 drives the pressure roller 34 and the swing frame 5 to swing downward at the same time, and the swinging of the pressure roller 34 and the swinging top of the pull roller 37 push down, so that the tension of the copper wire is enhanced, and the swing frame 5 swings downward from the horizontal to make the pull rod 54 further move along the low position of the protrusion 71 to the high position, and then the plug-in 8 is blocked and retained, and the pressure sleeve 7 moves relative to the plug-in 8 so that the multiple springs 73 are squeezed and deformed to contact the inner wall of the copper wire drum 4, thereby enhancing the resistance of the copper wire drum 4 when rotating and adjusting and lifting the tension of the copper wire on the copper wire drum 4.

[0053] Therefore, by adjusting the swing frame 5 and the synchronous swing adjustment of the feedback frame 3, the tension of the tensioned copper wire can be adjusted in a timely and adaptive manner. At the same time, when the copper wire on the copper wire reel 4 is used up, the tension of the copper wire drops rapidly, and the first end of the feedback frame 3 further swings down. At this time, the first end of the feedback frame 3 swings down to make the long roller 32 slide along the slot 51 to the opening 52, and then the long roller 32 disengages from the opening 52. At this time, the torsion spring 56 releases the stored force to drive the swing frame 5 to swing up quickly, and the swing frame 5 is reset and the plug-in spring 74 pulls and resets the extension rod 83, so that the plug-in 8 is disengaged from the copper wire reel 4, and then the limit of the copper wire reel 4 is released. The rubber limit block 86 is further limited to prevent the copper wire reel 4 from being thrown out of the limit. This is to facilitate the subsequent rapid replacement of the copper wire reel 4.

[0054] A method for using a winding mechanism for cable production, the steps of which are as follows: S1, place the copper wire reel 4 between the two main mounting frames 21, and align the disc hole on the copper wire reel 4 with the accommodating cavity 24, and then flip the swing frame 5 to switch the swing frame 5 from the vertical state to the horizontal state, at this time, the swing frame 5 is rotated to move the lever 54 along the low position of the protrusion 71 to the high position and squeeze the pressing sleeve 7 to slide, and then the pressing sleeve 7 drives the two plug-ins 8 to be inserted into the disc hole during the sliding process to limit the copper wire reel 4, thereby realizing the rapid installation of the copper wire reel 4; S2, by further swinging the swing frame 5 downward, and then sliding the long roller 32 on the seesaw 31 into the dial groove 51 along the opening 52, while the torsion spring 56 is in a state of deformation and force storage, and then by arranging the copper wire on the copper wire drum 4 along the bottom of the pressure roller 34 and the top of the dial roller 37, during the copper wire twisting process, the copper wire tension is used to drive the pressure roller 34 to lift up, and in the normal twisting state of the copper wire, the swing frame 5 is in a horizontal state, and the first end of the feedback frame 3 is tilted downward, and when the tension of the copper wire decreases, the deadweight of the feedback frame 3 drives the pressure roller 34 and the swing frame 5 to swing downward at the same time, and when the swing frame 5 swings downward from the horizontal, the dial rod 54 further moves along the low position of the protrusion 71 to the high position, and then the plug-in 8 is blocked and retained, and the pressure sleeve 7 moves relative to the plug-in 8 so that the multiple spring pieces 73 are squeezed and deformed to contact the inner wall of the copper wire drum 4, thereby enhancing the resistance of the copper wire drum 4 when rotating and adjusting the tension of the copper wire on the copper wire drum 4; S3, when the pressure roller 34 swings down, the roller 37 swings up, and when the roller 37 swings up, the copper wire is moved close to the cushion 9, and the copper wire is squeezed and twisted between the roller 37 and the cushion 9, so that the tension of the copper wire is increased and the resistance is increased when it is pulled. When the tension of the copper wire is increased, the copper wire will move the pressure roller 34 upward, and at the same time, the swing frame 5 swings up to reduce the squeezing force of the spring 73 on the copper wire drum 4, and the tension of the copper wire is reduced; S4, when the copper wire on the copper wire reel 4 is broken, the roller 37 is swung up to the maximum angle to further move the copper wire close to the cushion 9. At this time, the copper wire is squeezed by the cushion 9 and the roller 37 to limit and fix the copper wire to a certain extent, so as to reduce the influence of the large-scale displacement caused by the copper wire twisting and pulling and the loose copper wire caused by the copper wire breaking and displacement on the twisted cable. At the same time, the pressure roller 34 is swung down to the maximum angle, and the pressure roller 34 pushes on the pad 61 to further clamp the copper wire; S5. When the copper wire on the copper wire reel 4 is used up, the tension of the copper wire drops rapidly at this time, and the first end of the feedback frame 3 swings further downward. At this time, since the first end of the feedback frame 3 swings downward, the long roller 32 slides along the dial groove 51 to the opening 52. Subsequently, the long roller 32 disengages from the opening 52. At this time, the torsion spring 56 releases the stored energy to drive the swing frame 5 to swing upward rapidly. Under the upward swing reset of the swing frame 5 and the pulling reset of the plug-in spring 74 on the extension rod 83, the plug 8 disengages from the copper wire reel 4, thereby releasing the limit on the copper wire reel 4. Further limiting through the rubber limit block 86 can prevent the copper wire reel 4 whose limit is released from being thrown out and disengaged. So as to facilitate the subsequent rapid replacement of the copper wire reel 4.

[0055] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
