Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, specifically to a cable winding device for cable production. Background Technology

[0002] Cable cores are typically composed of multiple stranded metal conductors. These conductors are made from metal rods or wires through a drawing process. The drawn wires then need to be wound up using a take-up device. Current take-up devices usually employ an I-beam reel to wind the wires, allowing them to wind onto the bottom of the reel. To ensure even winding and prevent localized accumulation or loosening of the wires, the winding wheel needs to move back and forth along the axial direction of the reel for uniform distribution. The reciprocating movement of the winding wheel and the winding power are usually powered by separate power sources, resulting in significant energy consumption. Furthermore, during the winding process, as the diameter of the wire coil increases, the wire tension constantly changes. If the tension cannot be adjusted in time during winding, the risk of wire breakage is high, affecting the winding effect.

[0003] A Chinese patent document with publication number CN208631817U discloses a wire drawing machine winding device, comprising a constant-speed wheel set through which the drawn wire bundle passes sequentially, at least one first adjusting wheel, and a take-up reel. The constant-speed wheel set includes a fixed wheel and a second adjusting wheel. The first shaft of the fixed wheel is fixedly arranged, and the second shaft of the second adjusting wheel is parallel to the first shaft, with the distance between them elastically varying according to the tension of the wire. The first adjusting wheel includes a fixed shaft and a rocker arm. One end of the rocker arm elastically rotates around the fixed shaft, and the other end of the rocker arm is fixed to a guide wheel for conveying the wire bundle. The take-up reel includes a main body for winding the wire bundle, a first power source driving the main body to rotate, and a second power source driving the main body to reciprocate linearly along an axis. This patent requires two power sources to operate, as the first power source drives the main body of the take-up reel to rotate, and the second power source drives the main body to reciprocate linearly along an axis. This results in significant power consumption. Utility Model Content

[0004] The main objective of this invention is to overcome the deficiencies of the prior art and provide a cable winding device for cable production.

[0005] To achieve the above objectives, the present invention proposes a cable production take-up device, comprising a machine body with a take-up chamber on the front side. The take-up chamber contains a first adjusting component, a reversing wheel, a second adjusting component, a guiding component, and a take-up component. The stretched wire passes sequentially through the first adjusting component, the reversing wheel, the second adjusting component, and the guiding component before being taken up onto the take-up component. The take-up component includes a take-up reel, a take-up shaft, and a take-up motor. The take-up reel is detachably mounted on the take-up shaft, and one end of the take-up shaft extends... The take-up shaft extends to the back of the take-up chamber and connects to the output end of the take-up motor. A drive gear is mounted on the take-up shaft. The guide assembly includes a telescopic rod, an L-shaped support rod, a connecting rod, and a reciprocating screw. One end of the telescopic rod extends to the back of the take-up chamber and connects to the connecting rod. The other end of the telescopic rod connects to one end of the L-shaped support rod, which has a guide wheel on its other end. The reciprocating screw has a driven gear that meshes with the drive gear. The connecting rod is connected to the reciprocating screw. While the take-up motor drives the take-up reel to rotate for winding, it simultaneously drives the reciprocating screw to rotate continuously. The connecting rod reciprocates on the reciprocating screw, causing the guide wheels on the telescopic rod and L-shaped support rod to reciprocate longitudinally. This ensures that the yarn is neatly wound layer by layer on the take-up reel, evenly distributed, avoiding localized accumulation or looseness. The guide wheels can move back and forth without an additional power source, saving energy.

[0006] To further optimize the technical solution, a support frame is provided on the back of the winding chamber. The reciprocating screw is rotatably mounted on the support frame and parallel to the take-up shaft. The support frame has an elongated limiting hole parallel to the reciprocating screw, and the connecting rod slides through the elongated limiting hole. By setting the elongated limiting hole, the connecting rod can only slide left and right along the elongated limiting hole and cannot rotate.

[0007] To further optimize the technical solution, a guide rod is provided on the L-shaped support rod. The guide rod guides the wire into the guide wheel.

[0008] To further optimize the technical solution, the diameter of the driving gear is smaller than the diameter of the driven gear, enabling speed reduction transmission between the driving gear and the driven gear.

[0009] To further optimize the technical solution, the side wall of the machine body is provided with a wire inlet that connects to the interior of the winding chamber, and a wire guide roller is provided at the wire inlet. The wire guide roller ensures that the wire enters the first adjustment component along a predetermined trajectory, reducing the swaying or deviation of the wire before entering the first adjustment component, and avoiding wire breakage problems caused by unstable direction.

[0010] To further optimize the technical solution, the first adjustment component includes a constant speed wheel and an adjustment wheel. The constant speed wheel is mounted on the inner wall of the winding chamber via a mounting shaft. An adjustment mounting seat is fixedly mounted on the mounting shaft, and the adjustment wheel is movably mounted on the adjustment mounting seat, allowing the distance between the adjustment wheel and the constant speed wheel to vary. Specifically, the adjustment mounting seat has an elongated mounting hole, within which a slider slides. A spring is located at the bottom of the slider, with one end of the spring abutting against the inner bottom surface of the elongated mounting hole and the other end abutting against the bottom surface of the slider. The adjustment wheel is mounted on the slider via the adjustment shaft. Through the cooperation of the spring, slider, and elongated mounting hole, a passive tension buffering mechanism is formed. When the wire tension changes, the distance between the constant speed wheel and the adjustment wheel changes, and the spring is compressed, generating a counterforce to absorb tension fluctuation energy, thus achieving tension adjustment.

[0011] To further optimize the technical solution, the second adjustment component includes a swing arm, a top wheel, and a fixed rod. The fixed rod is horizontally and longitudinally fixed to the inner wall of the winding chamber. The middle part of the swing arm is rotatably connected to the fixed rod. The top wheel is located at the end of the swing arm away from the fixed rod. Tension is achieved by the top wheel pressing against the wire. The tension is balanced by the torque formed by the weight of the swing arm and the top wheel. When the winding speed is stable, the swing arm is in a horizontal and stable state. If the winding speed is too fast or too slow, the tension change will break the balance, causing the swing arm to drive the top wheel to tilt upwards or downwards.

[0012] To further optimize the technical solution, a limiting rod is longitudinally provided on the inner wall of the winding chamber, and the tail end of the swing rod corresponds to the limiting rod. When the swing rod flips downward, its tail end abuts against the limiting rod, thus limiting its movement.

[0013] To further optimize the technical solution, a counterweight is provided on the swing arm, and a locking bolt is provided on the counterweight. The preset tension value can be fine-tuned by adjusting the position of the swing arm's center of gravity by moving the counterweight.

[0014] The beneficial effects of this utility model include: the take-up motor drives the take-up reel to rotate, providing take-up power while simultaneously driving the reciprocating screw to rotate continuously. This, in conjunction with the connecting rod sleeved on the reciprocating screw, drives the telescopic rod to extend and retract, thereby causing the guide wheel on the L-shaped support rod to move back and forth. This ensures that the wire is neatly wound layer by layer on the take-up reel, evenly distributed, avoiding local accumulation or looseness, dispersing the contact pressure between the wire and the take-up reel, reducing local frictional heat accumulation, and extending the life of the equipment and the wire. The guide wheel can move back and forth without an additional power source, saving energy. Furthermore, the combined use of the first and second adjustment components forms dual tension control, enabling rapid adjustment of tension balance during the take-up process to prevent wire breakage or loosening.

[0025] Please see Figures 1 to 5One embodiment of the cable production take-up device discloses a body 1, with a take-up chamber 101 on the front of the body 1. The take-up chamber 101 contains a first adjusting component 2, a reversing wheel 3, a second adjusting component 4, a guide component 5, and a take-up component 6. The stretched wire enters the take-up chamber 101, passes sequentially through the first adjusting component 2, the reversing wheel 3, the second adjusting component 4, and the guide component 5, and is then wound onto the take-up component 6. The take-up component 6 includes a take-up reel 601, a take-up shaft 602, and a take-up motor 603. The take-up reel 601 is detachably sleeved on the take-up shaft 602, one end of which extends to the back of the take-up chamber 101 and is connected to the take-up motor 603. The output end of the take-up motor 603 on the back of the winding chamber 101 is connected to the take-up shaft 602, which drives the take-up reel 601 to rotate synchronously for winding. A drive gear 604 is provided on the take-up shaft 602. The guide assembly 5 includes a telescopic rod 501, an L-shaped support rod 502, a connecting rod 503, and a reciprocating screw 504. One end of the telescopic rod 501 extends to the back of the winding chamber 101 and is fixedly connected to the top end of the connecting rod 503. The other end of the telescopic rod 501 is connected to one end of the L-shaped support rod 502. A guide wheel 507 is provided on the other end of the L-shaped support rod 502. A driven gear 505 is provided on the reciprocating screw 504. Driven gear 505 meshes with driving gear 604, and the bottom of connecting rod 503 is connected to reciprocating screw 504. Specifically, the diameter of driving gear 604 is smaller than that of driven gear 505, enabling speed reduction transmission between driving gear 604 and driven gear 505. Take-up motor 603 is a stepper motor or servo motor, and take-up shaft 602, telescopic rod 501, and reciprocating screw 504 are arranged parallel to each other. In this embodiment, take-up motor 603 drives take-up reel 601 to rotate, providing take-up power, and simultaneously drives reciprocating screw 504 to rotate continuously through the meshing transmission of driving gear 604 and driven gear 505, engaging the connecting rod. The connecting rod 503 on the reciprocating screw 504 moves back and forth, driving the telescopic rod 501 to extend and retract, which in turn drives the guide wheel 507 on the L-shaped support rod 502 to move back and forth, so that the wire is neatly wound layer by layer on the take-up reel 601 and evenly distributed, avoiding local accumulation or looseness, dispersing the contact pressure between the wire and the take-up reel 601, reducing local frictional heat accumulation, and extending the life of the equipment and the wire. The guide wheel 507 can move back and forth without the need for an additional power source, saving energy. At the same time, the first adjustment component 2 and the second adjustment component 4 work together to form dual tension control, which can quickly adjust the dynamic balance of tension and prevent wire breakage or loosening.

[0026] In a preferred embodiment, a support frame 102 is provided on the back of the winding chamber 101. The reciprocating screw 504 is rotatably mounted on the support frame 102 and parallel to the take-up shaft 602. The support frame 102 is provided with an elongated limiting hole 103 parallel to the reciprocating screw 504. The connecting rod 503 slides through the elongated limiting hole 103. By providing the elongated limiting hole 103, the connecting rod 503 can only slide left and right along the elongated limiting hole 103 and cannot rotate.

[0027] In a preferred embodiment, a guide rod 506 is provided on the L-shaped support rod 502, through which the wire is guided into the guide wheel 507.

[0028] In a specific example, a wire inlet 104 is provided on the side wall of the machine body 1, which connects to the inside of the winding chamber 101. The wire inlet 104 is positioned at the same level as the first adjustment component 2. A wire guide roller 7 is provided at the wire inlet 104. Specifically, a "grid" structure composed of multiple wire guide rollers 7 precisely controls the transmission route of the wire, ensuring that the wire enters the first adjustment component 2 along a predetermined trajectory, reducing the swaying or deviation of the wire before entering the first adjustment component 2, and avoiding wire breakage caused by unstable direction.

[0029] In a specific example, the first adjustment component 2 includes a constant speed wheel 201 and an adjustment wheel 202. The constant speed wheel 201 is mounted on the inner wall of the winding chamber 101 via a mounting shaft 203. An adjustment mounting seat 204 is fixedly mounted on the mounting shaft 203. The adjustment wheel 202 is movably mounted on the adjustment mounting seat 204, allowing the distance between the adjustment wheel 202 and the constant speed wheel 201 to vary. Specifically, an elongated mounting hole 205 is provided on the adjustment mounting seat 204. A slider 206 is slidably mounted in the elongated mounting hole 205. A spring 207 is provided at the bottom of the slider 206. One end of the spring 207 abuts against the inner bottom surface of the elongated mounting hole 205, and the other end of the spring 207 abuts against the bottom surface of the slider 206. The adjustment wheel 202 is mounted on the slider 206 via an adjustment shaft 208. The combination of spring 207, slider 206 and elongated mounting hole 205 forms a passive tension buffer mechanism. When the tension of the wire increases, the adjusting wheel 202 is pulled by the tension, which drives the slider 206 to slide along the elongated mounting hole 205, changing the distance between the constant speed wheel 201 and the adjusting wheel 202. The spring 207 is compressed to generate a reverse force to absorb the tension fluctuation energy, thereby achieving dynamic tension balance adjustment and ensuring the winding effect.

[0030] In a specific example, the second adjustment component 4 includes a swing arm 401, a top wheel 402, and a fixed rod 403. The fixed rod 403 is horizontally and longitudinally fixed to the inner wall of the take-up chamber 101. The middle part of the swing arm 401 is rotatably connected to the fixed rod 403. The top wheel 402 is located at the end of the swing arm 401 away from the fixed rod 403. By setting the second adjustment component 4 between the reversing wheel 3 and the guide component 5, the top wheel 402 abuts against the wire to tension it. Its tension is balanced by the torque formed by the weight of the swing arm 401 and the top wheel 402. When the take-up speed is stable, the swing arm 401 is in a horizontal and stable state. If the take-up speed is too fast or too slow, the tension change will break the balance, causing the swing arm 401 to drive the top wheel 402 to tilt up or down to adjust the tension.

[0031] In a specific example, a limiting rod 105 is longitudinally provided on the inner wall of the winding chamber 101. The tail end of the swing rod 401 corresponds to the limiting rod 105. Specifically, the limiting rod 105 can abut behind the fulcrum of the swing rod 401. When the swing rod 401 flips downward, the tail end abuts against the limiting rod 105 and plays a limiting role, preventing the swing rod 401 from continuing to droop. A counterweight 404 is provided on the swing rod 401, and a locking bolt 405 is provided on the counterweight 404. The counterweight 404 is set on the rod from the fulcrum of the swing rod 401 to the top wheel 402. The counterweight 404 can move on the rod and be locked and positioned by the locking bolt 405. The contact pressure of the top wheel 402 can be adjusted by moving the position of the counterweight 404 to adjust the position of the center of gravity of the swing rod to fine-tune the preset tension value.
