Description

Technical Field

[0001] This utility model relates to the technical field of copper wire rewinding machines, specifically a copper wire rewinding machine for cable production. Background Technology

[0002] Copper wire rewinding machine is a key pre-processing equipment in cable production. Its core function is to rewind the original wire roll (such as a large coil of heavy copper wire) into a small coil of copper wire with constant tension that meets the requirements of subsequent stranding and insulation coating processes. It must simultaneously meet three core requirements: "stable tension, uniform wire laying, and low wire breakage rate".

[0003] Currently, the use of a conveyor wheel, wire guide, and reciprocating screw evenly winds the copper wire onto the take-up roller: the conveyor wheel guides the copper wire from the original coil to the take-up end, and the reciprocating screw, through rotation, drives the wire guide to reciprocate along the screw axis, causing the copper wire to be evenly wound onto the surface of the take-up roller at a preset pitch, forming a regular copper wire coil. However, this structure has a significant adaptability defect—because the length of the reciprocating screw is fixed, the reciprocating stroke of the wire guide is strictly limited, and it cannot be flexibly adjusted according to changes in the size of the take-up roller. When production requirements change and take-up rollers of different lengths need to be replaced, the movement range of the guide wire cannot match the effective winding area of ​​the new take-up roller. If the length of the take-up roller is greater than the screw stroke, the guide wire cannot cover the two ends of the take-up roller, resulting in the copper wire only winding in the middle of the take-up roller, causing the problem of "too thick in the middle and empty at both ends". This not only wastes the space of the take-up roller, but also requires secondary rewinding to meet the roll diameter requirements of subsequent processes. If the length of the take-up roller is less than the screw stroke, the guide wire will go beyond the edge of the take-up roller when it reciprocates, causing the copper wire to wind on the shoulder of the take-up roller, forming "flying wire". In view of this, a copper wire rewinding machine for cable production is proposed. Utility Model Content

[0004] The main objective of this invention is to provide a copper wire rewinding machine for cable production, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention proposes a copper wire rewinding machine for cable production, comprising a machine body, a rotating shaft rotatably connected within the machine body, the rotating shaft being driven by a drive module within the machine body, a take-up roller detachably connected to the rotating shaft via a pressure ring, and a wire guiding mechanism provided on the machine body, the wire guiding mechanism comprising: A fixed base is fixedly connected to the outer wall of the machine body on the side near the take-up roller, and a lead screw is rotatably connected to the inner surface of the fixed base; A speed reducer is fixedly connected to the outer wall of the fixed base. The speed reducer is driven by a motor. The output shaft of the speed reducer is fixed to a lead screw. A guide rod is fixedly connected to the inner surface of the fixed base. It also includes a positioning component and a transmission component, wherein the positioning component is penetrated by a guide rod and the transmission component is penetrated by a lead screw.

[0006] Furthermore, the positioning component is provided in two sets, and the two sets are symmetrically arranged on both sides of the transmission component.

[0007] Furthermore, the positioning component includes a block, a fixing block is fixedly connected to the outer wall of the block, an elastic abutment switch is fixedly connected to the outer wall of the fixing block, a connecting plate is fixedly connected to the outer wall of the block, the connecting plate is penetrated by a round rod and slidably connected to the round rod, a clamping block and a pull plate are fixedly connected to both ends of the round rod respectively, the clamping block is located at the end of the round rod near the guide rod, and the connecting plate and the pull plate are elastically connected by a tension spring.

[0008] Furthermore, the block is penetrated by a guide rod and slidably connected to the guide rod. A through-hole is provided in the middle of the block, and the diameter of the through-hole is larger than the diameter of the lead screw. The lead screw passes through the through-hole, and the clamping block is pressed against the guide rod under the action of a tension spring.

[0009] Furthermore, the transmission component includes a movable block, which is threadedly connected to a lead screw. The movable block is penetrated by a guide rod and slidably connected to the guide rod. An abutment block is fixedly connected to the outer wall of the movable block. A horizontal plate is fixedly connected to the top of the movable block. A guide wheel one and a guide wheel two are rotatably connected to the horizontal plate.

[0010] Furthermore, the guide wheels are provided in two sets, which are symmetrically arranged on both sides of the horizontal plate.

[0011] Furthermore, an L-plate is fixedly connected to the bracket of the second guide wheel, and an elastic telescopic rod is fixedly connected to the outer wall of the L-plate. The telescopic end of the elastic telescopic rod is wedge-shaped, and the telescopic ends of two adjacent elastic telescopic rods abut against each other.

[0012] This utility model provides a copper wire rewinding machine for cable production. It has the following advantages: (1) The copper wire rewinding machine for cable production can flexibly adapt to different lengths of take-up rollers through the coordinated design of positioning components and transmission components. The two sets of positioning components are fixed by clamping blocks and guide rods, and the spacing can be adjusted according to the length of the take-up roller to limit the reciprocating stroke of the transmission components. When the moving block drives the guide wheel to the positioning component, the abutting block triggers the elastic abutting switch, and the reducer can control the screw to rotate in reverse to ensure that the wire guide range is accurately matched with the effective winding area of ​​the take-up roller. This avoids the problem of "too thick in the middle and empty at both ends" caused by the take-up roller being too long, and also prevents the problem of "flying wire" caused by the take-up roller being too short.

[0013] (2) The copper wire rewinding machine for cable production forms a triangular guiding structure through the guide wheel one of the transmission component and the guide wheel two symmetrically arranged, which can limit the copper wire in multiple directions to avoid the copper wire from deviating or shaking during transmission. At the same time, under the action of the wedge-shaped telescopic end of the elastic telescopic rod, the copper wire can be easily inserted into the guide wheel two, and the wedge-shaped telescopic end of the elastic telescopic rod can limit the copper wire to prevent the copper wire from running out and maintain stable transmission tension.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model proposes a copper wire rewinding machine for cable production, including a machine body 1, a rotating shaft 2 rotatably connected in the machine body 1, the rotating shaft 2 being driven by a drive module in the machine body 1, a take-up roller 3 being detachably connected to the rotating shaft 2 via a pressure ring 4, and a wire guiding mechanism 5 being provided on the machine body 1.

[0020] In this embodiment of the invention, the wire guiding mechanism 5 includes a fixed base 51, a reducer 53, a positioning component 56, and a transmission component 57. The fixed base 51 is fixedly connected to the outer wall of the machine body 1 near the take-up roller 3. A lead screw 52 is rotatably connected to the inner surface of the fixed base 51. The reducer 53 is fixedly connected to the outer wall of the fixed base 51 and is driven by a motor 54. The output shaft of the reducer 53 is fixed to the lead screw 52. A guide rod 55 is fixedly connected to the inner surface of the fixed base 51. The positioning component 56 is penetrated by the guide rod 55, and the transmission component 57 is penetrated by the lead screw 52. Two sets of positioning components 56 are provided, and the two sets are arranged on both sides of the transmission component 57. The positioning component 56 includes a block 561. A fixing block 562 is fixedly connected to the outer wall of the block 561, and a fixing block 562 is fixedly connected to the outer wall of the fixing block 562. A resilient abutment switch 563 is provided. A connecting plate 564 is fixedly connected to the outer wall of a block 561. The connecting plate 564 is slidably connected to a round rod 565 through which a round rod 565 passes. A clamping block 566 and a pull plate 567 are fixedly connected to both ends of the round rod 565, respectively. The clamping block 566 is located at the end of the round rod 565 near the guide rod 55. The connecting plate 564 and the pull plate 567 are elastically connected by a tension spring. The block 561 is slidably connected to the guide rod 55 through which a guide rod 55 passes. A through-hole is provided in the middle of the block 561, and the diameter of the through-hole is larger than the diameter of the lead rod 52. The lead rod 52 passes through the through-hole. The clamping block 566 is pressed against the guide rod 55 under the action of the tension spring. The transmission component 57 includes a moving block 571, which is threadedly connected to the lead rod 52. The moving block 571 is slidably connected to the guide rod 55 through which a guide rod 55 passes.

[0021] To accommodate take-up rollers 3 of different lengths, first pull the pull plate 567 of the positioning component 56. This causes the clamping block 566 to move away from the guide rod 55 via the round rod 565, stretching the tension spring. At this time, the block 561 can slide along the guide rod 55. Adjust the distance between the two sets of positioning components 56 according to the effective winding length of the take-up roller 3, so that it is consistent with the effective length. Then, release the pull plate 567, and the tension spring will reset, pushing the clamping block 566 to re-clamp against the guide rod 55, thus fixing the position of the positioning component 56. During rewinding, motor 54 drives reducer 53 to rotate lead screw 52. Moving block 571, threadedly connected to lead screw 52, ​​slides back and forth along guide rod 55. When moving block 571 slides close to a positioning assembly 56, its outer wall contacting block 572 contacts elastic contact switch 563 on fixed block 562, triggering the switch. The switch sends a signal to reducer 53, controlling lead screw 52 to reverse rotation. This ensures the reciprocating stroke of transmission assembly 57 perfectly corresponds to the effective winding area of ​​take-up roller 3, guaranteeing precise matching between the guide wire range and the effective winding area of ​​take-up roller 3. This avoids both the "too thick in the middle, empty at both ends" problem caused by excessively long take-up roller 3 and the "flying wire" problem caused by excessively short take-up roller 3.

[0022] Furthermore, an abutment block 572 is fixedly connected to the outer wall of the movable block 571, and a horizontal plate 573 is fixedly connected to the top of the movable block 571. A guide wheel 1 574 and a guide wheel 2 575 are rotatably connected to the horizontal plate 573. Two sets of guide wheels 2 575 are provided, and the two sets of guide wheels 2 575 are symmetrically arranged with the center line of the horizontal plate 573 as the axis of symmetry. When the copper wire is transmitted, the copper wire is first passed around the guide wheel 1 574 and the two sets of guide wheels 2 575 in sequence, and the three form a "triangular support" structure. The copper wire fits into the groove of the three sets of guide wheels, and the rubber layer on the inner wall of the groove increases the friction with the copper wire, limiting the horizontal deviation of the copper wire.

[0023] Furthermore, an L-plate 576 is fixedly connected to the bracket of the second guide wheel 575, and an elastic telescopic rod 577 is fixedly connected to the outer wall of the L-plate 576. The telescopic end of the elastic telescopic rod 577 is wedge-shaped, and the telescopic ends of two adjacent elastic telescopic rods 577 abut against each other. During the wire locking process, the copper wire pushes the wedge-shaped telescopic end of the elastic telescopic rod 577, and the telescopic end is squeezed and contracted, providing space for the copper wire to be locked in. After the copper wire is completely inserted into the groove of the second guide wheel 575, the elastic telescopic rod 577 returns to its original position under its own elastic force, and the wedge-shaped telescopic end of the elastic telescopic rod 577 returns to the edge of the groove, forming a "blocking limit" to prevent the copper wire from coming out of the groove.

[0024] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install, and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here. The standard parts used in this application can all be purchased from the market. The specific connection methods of each part are all connected by conventional means such as riveting and welding that are mature in the prior art. The standard parts are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art.

[0025] In use, the copper wire is first passed around the first guide wheel 574 and the two sets of second guide wheels 575 in sequence. During the wire clamping process, the copper wire pushes the wedge-shaped telescopic end of the elastic telescopic rod 577. The telescopic end is squeezed and contracted, providing space for the copper wire to be clamped. After the copper wire is completely inserted into the groove of the second guide wheel 575, the elastic telescopic rod 577 returns to its original position under its own elastic force. The wedge-shaped telescopic end of the elastic telescopic rod 577 returns to the edge of the groove, thus limiting the copper wire. Then, according to the take-up roller 3, the pull plate 567 is pulled, which drives the clamping block 566 away from the guide rod 55 through the round rod 565. The tension spring is stretched, and at this time, the square block 561 can slide along the guide rod 55. According to the effective winding length of the take-up roller 3, the distance between the two sets of positioning components 56 is adjusted to be consistent with the effective length. Then, the pull plate 567 is released, the tension spring returns and pushes the clamping block 566 to press against the guide rod 55 again, fixing the position of the positioning component 56. During the rewinding operation, the motor 54 drives the reducer 53 to rotate the lead screw 52. The moving block 571, which is threadedly connected to the lead screw 52, ​​slides back and forth along the guide rod 55. When the moving block 571 slides close to a certain positioning component 56, the abutment block 572 on its outer wall contacts the elastic abutment switch 563 on the fixed block 562 and triggers the switch. The switch sends a signal to the reducer 53 to control the lead screw 52 to reverse its rotation. At the same time, the copper wire is evenly wound onto the winding roller 3 by the rotation of the winding roller 3.
