Description

Technical Field

[0001] This utility model relates to the field of wire take-up machine technology, and in particular to a wire take-up machine. Background Technology

[0002] In the field of metal wire and cable processing, winding is a critical final step before the product is packaged and shipped. Traditional winding equipment is generally suitable for winding soft wires, which guides the wire to be arranged in an orderly manner and wound onto a reel or spool through a reciprocating mechanism.

[0003] However, existing take-up machines face significant challenges when processing metal wires with a certain degree of plasticity and high hardness. Unlike flexible conductors that can flexibly conform to the guide device, these metal wires possess strong rigidity and resilience. During the reciprocating winding process, a significant opposing force is generated between the wire and the mechanism, leading to instability in the winding process. The metal wires are difficult to arrange in an ideal conforming manner, resulting in crossovers, overlaps, and even tangled coils between the layers after winding. This problem not only affects the neatness and aesthetics of the coil but also causes inconvenience for subsequent storage, transportation, and use. Utility Model Content

[0004] To address the problem that existing take-up devices struggle to guarantee winding quality when handling metal wires with a certain degree of plasticity and high hardness, this invention provides a novel take-up mechanism that adapts to the characteristics of metal wires and improves the neatness of wire arrangement.

[0005] The technical solution is as follows: A wire take-up machine includes a frame, on which a wire-receiving wheel, a guide mechanism, and an I-beam wheel are sequentially arranged along the take-up direction; the guide mechanism includes a lead screw mounted on the frame and parallel to the axis of the I-beam wheel, a slide mounted on the upper end of the lead screw nut, and a trumpet-shaped guide tube located on the upper end of the slide. The larger diameter end of the trumpet-shaped guide tube faces the wire-receiving wheel, and the other end faces the I-beam wheel. An adjustment frame is connected to the lead screw nut, and one end of the adjustment frame is close to the I-beam wheel and has an end guide tube; it also includes a horizontal support frame located between the end guide tube and the trumpet-shaped guide tube, and the horizontal support frame has a slotted hole parallel to the axis of the I-beam wheel.

[0006] Preferably, a rotating platform is provided between the trumpet-shaped guide tube and the slide table. The rotating platform includes a base fixed to the upper surface of the slide table, a vertical shaft mounted on the base via bearings, and a bushing sleeve fitted on the upper end of the vertical shaft. The upper end of the bushing sleeve is provided with a clamping seat for clamping the trumpet-shaped guide tube. A long screw for assembling a nut is provided radially on the surface of the vertical shaft. A vertical groove adapted to the long screw is opened along the axial direction on the bushing sleeve. The lower end of the vertical groove is provided with an opening that allows the long screw to enter.

[0007] Preferably, the upper end of the base is provided with a plurality of pin holes along the vertical axis circumferentially, the axial direction of the pin holes being parallel to the axial direction of the vertical axis, wherein at least two pin holes are fitted with pins, and the two pins interfere with the long screw to limit the movement of the vertical axis within the angular range defined by the two pins.

[0008] Preferably, the opening of the trumpet-shaped guide tube has an inner chamfer.

[0009] Preferably, there are at least three wire-laying wheels, which are mounted on the frame via wheel frames. The three wire-laying wheels are arranged sequentially along the wire transmission direction, wherein the diameter of the middle wire-laying wheel is larger than the diameter of the wire-laying wheels on both sides.

[0010] Preferably, the adjusting frame includes a horizontal adjusting rod with one end fixed to a lead screw nut, and a vertical adjusting rod fixed to the horizontal adjusting rod by a first pipe clamp, wherein the vertical adjusting rod is provided with a second pipe clamp for holding the end guide tube.

[0011] Compared with the prior art, the present invention has the following advantages: 1. This utility model, by setting up a main guiding mechanism consisting of a slide table driven by a lead screw and a trumpet-shaped guide tube, combined with an adjustable end guide tube and a horizontal support frame with a slotted hole, forms a multi-level guiding and stable support system, which effectively suppresses the lateral swaying and jumping of the metal wire during the winding process, fundamentally solving the technical problems of uneven winding and overlapping wire layers, and significantly improving the winding quality and efficiency of the metal wire.

[0012] 2. The rotating table structure of this utility model allows for fine-tuning of the angle of the trumpet-shaped guide tube through the cooperation of the vertical shaft and the bushing. This better adapts to the wiring angle requirements of different rigid wires, alleviates the resistance between the wire and the guide mechanism, and further ensures smooth and neat wiring.

[0013] 3. This utility model uses the cooperation of pin shaft and pin hole to limit the adjustment range of the rotating table. The structure is simple and reliable. It can prevent the guide tube from deviating from the working position due to accidental rotation, and can also preset a safe swing range according to the characteristics of the wire to ensure the stability of the winding process.

[0014] 4. This utility model effectively reduces surface damage caused by sharp edges when hard metal wires enter the guide tube by beveling the inner side of the opening of the trumpet-shaped guide tube to form a smooth transition guide surface, thus combining guiding and protective functions.

[0015] 5. This utility model adopts a layout of wire-laying wheels with a large diameter in the middle and small diameter on both sides, which can produce a moderate pre-stretching and straightening effect on the wire, partially eliminating its internal stress, thereby reducing the springback tendency of the wire when winding, which is conducive to improving the tightness and neatness of the wire roll.

[0016] 6. This utility model uses an adjustment frame consisting of horizontal and vertical adjustment rods and pipe clamps to fix the end guide tube, which realizes flexible and precise adjustment of the position of the end guide tube in space, and can accurately align its outlet with the I-beam wheel, ensuring the accuracy of the starting point and position of the wiring.

[0022] 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.

[0023] like Figures 1 to 4 As shown, this utility model provides a wire take-up machine, the structure of which includes a frame 1, and a take-up roller 2, a guide mechanism 3, and an I-beam roller 4 arranged sequentially on the frame 1 along the take-up direction. The frame 1 adopts a box-type structure, providing a stable support foundation for the whole machine. The I-beam roller 4 is driven by a second servo motor, which is fixed on the frame 1 and is connected to the central shaft of the I-beam roller 4, which is rotatably mounted on the frame 1. The I-beam roller 4 is detachably mounted on the central shaft, which facilitates the unloading operation after take-up and the installation of new I-beam rollers.

[0024] The guiding mechanism 3 specifically includes: a lead screw 31 fixed to the frame 1 via a T-shaped support frame, with the axis of the lead screw 31 parallel to the axis of the I-beam wheel 4. A lead screw nut 32 is mounted on the lead screw 31, and one end of the lead screw 31 is directly connected to the first servo motor via a coupling to ensure transmission accuracy. A slide table 33 is fixed to the upper end of the lead screw nut 32 by bolts and can perform precise reciprocating motion along the axial direction of the lead screw 31 along with the lead screw nut 32.

[0025] A trumpet-shaped guide tube 34 is provided at the upper end of the slide table 33. This guide tube has a tapered structure, with a larger diameter at the inlet end facing the wire-laying wheel 2 and a smaller diameter at the outlet end pointing towards the H-beam wheel 4. This tapered structure can gradually guide and converge the wire, effectively dispersing the stress generated when bending rigid wire. In particular, the inner sides of both the outlet and inlet of the trumpet-shaped guide tube 34 are chamfered to form a smooth transition guide surface, which can minimize scratch damage to the surface of the metal wire.

[0026] In addition, to ensure the stability of the cable laying process, an adjusting frame 5 is fixed to the lead screw nut 32, and an end guide tube 51 is provided at its end near the I-beam wheel 4. A horizontal support frame 6 is installed on the frame 1 between the trumpet-shaped guide tube 34 and the end guide tube 51. This support frame has a precisely machined slotted hole 61 parallel to the axis of the I-beam wheel 4. This slotted hole structure effectively constrains the horizontal swing amplitude of the cable, forming a complete multi-stage guiding and stabilizing support system together with the front and rear guide tubes. Furthermore, the adjusting frame 5 adopts a modular adjustable design, including a horizontal adjusting rod 52, a vertical adjusting rod 54, and corresponding pipe clamp assemblies. One end of the horizontal adjusting rod 52 is fixed to the side of the lead screw nut 32 by bolts. The vertical adjusting rod 54 is connected to the horizontal adjusting rod 52 through a first pipe clamp 53, and the end guide tube 51 is fixed to the top of the vertical adjusting rod 54 through a second pipe clamp 55. Both the first pipe clamp 53 and the second pipe clamp 55 adopt a structure with locking bolts, which can realize flexible adjustment and reliable locking of the position of each rod.

[0027] In a preferred embodiment, to further enhance the adaptability of the device, a rotating platform 35 is provided between the flared guide tube 34 and the slide 33. This rotating platform includes a base 351 bolted to the upper surface of the slide 33, a vertical shaft 352 mounted on the base 351 via rolling bearings, a bushing 353 sleeved on the upper end of the vertical shaft 352, and a clamping seat 354 disposed on the upper end of the bushing 353 for clamping the flared guide tube 34. The surface of the vertical shaft 352 is radially provided with a long screw 355 for mounting a nut, and the bushing 353 is machined along its axial direction with a vertical groove 356 adapted to the long screw 355. The lower end of the vertical groove 356 has an opening allowing the long screw 355 to enter. Furthermore, it should be noted that the upper end of the base 351 has multiple pin holes 357 evenly distributed around the vertical axis 352, of which at least two pin holes are fitted with pins 358. These two pins 358 interfere with the long screw 355, thus limiting the rotation of the vertical axis 352 within a safe angle range. By selecting to insert the pins 358 into different pin holes 357, the range of rotation angle of the vertical axis 352 can be adjusted.

[0028] The lead screw 31 is controlled by a stroke control mechanism, which includes a limit switch 7 mounted on the lead screw nut 32. A smooth slide rod 71 is mounted parallel to the lead screw 31 at the upper end of the T-shaped support frame, and two independently adjustable limit blocks 72 are mounted on it, located on either side of the limit switch 7. By adjusting the distance between the two limit blocks 72, the reciprocating range of the slide table 33 can be precisely controlled. This range needs to be precisely set according to the effective winding length of the I-beam reel 4.

[0029] In the wire feeding section, the wire feeding rollers 2 adopt a three-wheel layout: the three wire feeding rollers are mounted on the frame 1 via roller frames 21 and arranged sequentially along the wire transmission direction. Among them, the middle wire feeding roller 22 has a larger diameter, while the two side wire feeding rollers 23 have smaller diameters, forming a unique undulating arrangement. This special layout can produce a moderate pre-stretching and straightening effect on the wire, effectively eliminating internal stress in the wire.

[0030] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the inventive concept, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
