Description

Technical Field

[0001] This invention relates to the field of wire harness processing technology, specifically an automatic winding and binding integrated forming machine for multi-branch wire harnesses. Background Technology

[0002] Cross-linked polyethylene insulated power cables (hereinafter referred to as cross-linked cables) are widely used in power transmission fields such as urban power grid transformation, building wiring and industrial and mining enterprises due to their excellent electrical insulation performance, heat resistance performance and mechanical and physical properties. In actual laying and application scenarios, in order to meet complex power distribution needs and facilitate line differentiation and management, it is often necessary to combine multiple cross-linked polyethylene insulated branch cables into multi-branch bundles and perform binding and insulation wrapping protection on their exterior.

[0003] Currently, the binding and wrapping of multi-branch cross-linked polyethylene insulated power cables mostly still adopts the traditional step-by-step semi-manual or single-machine operation method. Existing processing technology and equipment typically involve first manually or using simple equipment to bind and fix multiple dispersed branch cables with cable ties or binding wires, and then transferring them to a wrapping machine to cover them with polyethylene insulation tape. This step-by-step operation is not only cumbersome and labor-intensive in terms of transfer and handling, but also severely restricts production efficiency. Although the insulation layer of cross-linked polyethylene insulated power cables has excellent performance, it is prone to deformation or surface damage when subjected to uneven compression or friction. The manual binding force... It is difficult to maintain consistency, and problems such as loose binding leading to loose wire harnesses or tight binding causing damage and dents to the insulation layer are very likely to occur. In addition, it is difficult to ensure constant tension and overlap rate when manually wrapping polyethylene insulation tape, which can easily produce wrinkles or gaps, affecting the overall insulation protection quality of the formed wire harness. When multiple wire harnesses are processed in parallel at the same time, there is a lack of effective synchronous drive and guidance mechanism. When the scattered branch cables enter the processing area, they are very likely to cross, get stuck or deviate. Furthermore, it is difficult to accurately match the winding speed with the front binding and wrapping speed. When the winding traction force is too large, it will pull the cross-linked cable and cause the insulation layer to deform. When it is too small, the wire harness will become loose and piled up. Summary of the Invention

[0004] Technical problems to be solved

[0005] The purpose of this invention is to overcome the shortcomings of existing cross-linked polyethylene insulated power cables, such as low efficiency of step-by-step operation in multi-branch wire harness processing, unstable quality of manual binding and winding that easily damages the insulation layer, and easy jamming and deviation when processing multiple wires in parallel, and difficulty in matching the winding speed with the travel speed.

[0006] Technical solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: an automatic winding and binding integrated forming machine for multi-branch wire harnesses, comprising:

[0008] A cross-linked cable, wherein the cross-linked cable is composed of multiple branch cables;

[0009] A bundling and winding assembly, wherein a mounting frame is fixedly connected to the bottom of the bundling and winding assembly, and one end of several cross-linked cables passes through the interior of the bundling and winding assembly, for simultaneously automatically bundling and winding multiple cross-linked cables;

[0011] The take-up assembly is fixedly connected to the rear end surface of the mounting frame, and the cross-linked cable is wound around the outside of the take-up assembly. It is used to take up the cross-linked cable that has been automatically tied and wound, and at the same time pull the cross-linked cable through the inside of the binding and winding assembly at a uniform speed.

[0012] Furthermore, the bundling and wrapping assembly includes:

[0013] The operation panel has four operation panels, and a circular through hole is opened at the center of the operation panel. The cross-linked cable passes through the center of the through hole laterally. Two sliding grooves are opened on the outer side of the operation panel, and the sliding grooves are annular.

[0014] The stabilizing bar is arc-shaped, and its inner side is adapted to the sliding groove. The inner side of the stabilizing bar is slidably connected to the inside of the sliding groove.

[0015] A stabilizing frame is fixedly connected to both ends of a stabilizing bar, and the bottom of the stabilizing frame is fixedly connected to the surface of a mounting frame, for stabilizing and supporting the operating panel.

[0016] Furthermore, a bundling roller is movably connected to one side of the operating panel via a rotating shaft, and a bundling wire is wound around the outside of the bundling roller, with the other end of the bundling wire wound around the outside of the cross-linked cable.

[0017] Furthermore, on the other side of the operating panel, two symmetrically arranged polyethylene insulating tape rollers are movably connected via a rotating shaft. The outer side of the polyethylene insulating tape rollers is wrapped with polyethylene insulating tape, and the other ends of the two polyethylene insulating tapes are wrapped around the outside of the cross-linked cable that has been bundled with binding wires.

[0018] Furthermore, the control component includes:

[0019] A control motor is provided, the bottom of which is fixedly connected to a lifting frame, and the bottom of the lifting frame is fixedly connected to the surface of the mounting frame.

[0020] Two drive wheels are connected by a drive belt, and one of the drive wheels is fixedly connected to the output end of the control motor by a connecting shaft and a coupling.

[0021] A drive gear, the axis of which is fixedly connected to the axis of another transmission wheel via a connecting shaft;

[0022] The lifting frame is fixedly connected to a connecting seat on one side, and the connecting seat is U-shaped. The drive gear and transmission wheel are movably connected to the inside of the connecting seat through a rotating shaft.

[0023] Furthermore, each of the outer middle positions of the operating disk is fixedly connected to a transmission gear ring, and the transmission gear rings mesh with each other. The drive gear is located directly above one of the middle transmission gear rings, and the drive gear meshes with the transmission gear ring to drive one of the transmission gear rings, thereby causing it to drive the other transmission gear rings to rotate.

[0024] Furthermore, the take-up assembly includes:

[0028] Compared with existing technologies, this automatic winding and binding integrated forming machine for multi-branch wire harnesses has the following advantages:

[0029] I. This invention, through the set bundling and winding assembly, utilizes the rotation of the operating disc to drive the bundling wire roller and the polyethylene insulation tape roller to revolve around the cross-linked cable, realizing the simultaneous tight binding of multiple branch cables by the bundling wire and the circumferential cross-winding of the two polyethylene insulation tapes.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] like Figures 1-8 As shown, the present invention provides a technical solution: an automatic winding and binding integrated forming machine for multi-branch wire harnesses, comprising:

[0044] Cross-linked cable 1, which is composed of multiple branch cables;

[0045] The binding and winding assembly 2 has a mounting bracket 3 fixedly connected to its bottom, and one end of several cross-linked cables 1 passes through the interior of the binding and winding assembly 2, which is used to automatically bind and wind multiple cross-linked cables 1 at the same time.

[0046] Control component 4 is fixedly connected to the surface of mounting bracket 3, and the output end of control component 4 is fixedly connected to the outside of binding and winding component 2, for driving binding and winding component 2 to rotate;

[0047] The take-up assembly 5 is fixedly connected to the rear end surface of the mounting frame 3, and the cross-linked cable 1 is wound around the outside of the take-up assembly 5. It is used to take up the cross-linked cable 1 that has been automatically tied and wound, and at the same time pull the cross-linked cable 1 through the inside of the binding and winding assembly 2 at a uniform speed.

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, the bundling and winding assembly 2 includes four operating discs 201 arranged side by side. A circular through-hole 202 is provided at the center of each operating disc 201 for the cross-linked cable 1 to pass through laterally, providing a channel for multiple branch cables to converge and pass through. To ensure the stability of the operating discs 201 during rotation and winding, symmetrical annular sliding grooves 203 are provided on their outer sides. Arc-shaped stabilizing bars 204 slide and engage within the sliding grooves 203. Combined with a stabilizing frame 205 fixed to the mounting bracket 3, the stabilizing bars 204 are rigidly supported at both ends, creating a robust limiting and support system. This structure allows the operating discs 201 to rotate smoothly while effectively preventing radial runout and offset during high-speed operation, ensuring the accuracy of wire harness processing.

[0049] The operating panel 201 is equipped with binding and wrapping mechanisms on both sides to achieve integrated forming of the wire harness. One side of the operating panel 201 is movably connected to a binding roller 206 via a rotating shaft. As the operating panel 201 rotates, binding threads 207 are released, tightly binding and fixing multiple dispersed branch cables into a bundle. The other side has two symmetrically arranged polyethylene insulation tape rollers 208, which release polyethylene insulation tape 209 as the panel revolves. The two released polyethylene insulation tapes 209 are wrapped in a crisscross pattern around the outside of the cross-linked cable 1 already bound with binding threads 207. Through the continuous rotation of the operating panel 201, the internal wire cores are sequentially gathered and secured, and the external insulation protective layer is cross-wrapped, simultaneously achieving the dual processing effects of binding and insulation wrapping.

[0050] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the control component 4 serves as the power hub of the entire machine, responsible for providing stable rotational driving force for the winding and binding of the wire harness. It mainly consists of a control motor 401 and a pulley transmission mechanism. The control motor 401 is securely mounted on the surface of the mounting frame 3 via a lifting frame 402. A U-shaped connecting seat 405 is fixedly connected to one side of the lifting frame 402, providing a reliable support base for the transmission components. During operation, the control motor 401 starts, driving one transmission wheel 403 directly connected to its output end to rotate. Power is transmitted to another transmission wheel 403 via a transmission belt 407, which in turn drives the drive gear 404 to rotate synchronously through the connecting shaft. This not only ensures smooth operation but also effectively isolates the influence of motor vibration on winding accuracy.

[0051] To achieve efficient synchronous operation of multiple control panels 201, a transmission gear ring 406 is fixed at the center of the outer side of each of the four control panels 201, and the four transmission gear rings 406 mesh with each other sequentially to form a linkage relationship. A drive gear 404 is precisely positioned above and meshes with the central transmission gear ring 406. When the drive gear 404 rotates, it directly drives the central transmission gear ring 406 to rotate, and then, through the meshing between the gear rings, synchronously drives the other three transmission gear rings 406 to rotate. This single-input, multi-output gear linkage design requires only one motor to drive the four control panels 201 to rotate synchronously and at the same speed. This ensures a high degree of consistency in the bundling and winding rhythm of multiple cross-linked cables 1, simplifies the power source and control system, and improves the reliability and energy efficiency of the equipment operation.

[0052] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the take-up assembly 5 consists of several connecting frames 501 fixed to the rear surface of the mounting frame 3 and a winding roller 502 rotatably connected to its top. The connecting frames 501 and the operation panel 201 are arranged in a one-to-one correspondence to ensure that multiple wire harnesses are wound independently without interference. The winding roller 502 is equipped with an automatic drive rotation structure, which can automatically adjust the winding speed in real time during the winding process to accurately match the traveling speed of the cross-linked cable 1, avoiding excessive pulling and damage or loosening of the wire harness due to inconsistent speeds, and providing reliable power traction and speed guarantee for continuous automated operation.

[0053] To ensure the straightness and stability of the cross-linked cable 1 during threading and processing, two symmetrically distributed guide cylinders 503 are fitted on the outer side of the cable and are securely connected to the mounting frame 3 via a support strip 504 at the bottom. The two guide cylinders 503 are located on the front and rear sides of the operating panel 201, respectively. The inlet of the front guide cylinder 503 is designed in a trumpet shape, which can smoothly converge and guide multiple branch cables into the axis of the operating panel 201, effectively preventing jamming and deviation at the initial threading stage. The rear guide cylinder 503 provides straight-line constraint for the formed wire bundle that has been bound and wound, ensuring its smooth movement without deviation. This protects the newly wound insulation layer from frictional misalignment and ensures the neatness of subsequent winding and arrangement.

[0054] Working principle: The cross-linked cable 1, composed of multiple branch cables, is sequentially passed through the front-end trumpet-shaped guide cylinder 503, the through holes 202 at the axis of the four operating discs 201, and the rear-end guide cylinder 503, and finally fixedly connected to the outside of the winding roller 502 of the take-up assembly 5. At the same time, the binding wire 207 on the binding roller 206 and the polyethylene insulation tape 209 on the polyethylene insulation tape roller 208 are pulled out and pre-fixed on the surface of the cross-linked cable 1. The front-end trumpet-shaped guide cylinder 503 facilitates the convergence and guidance of the multiple branch cables, preventing jamming during threading.

[0055] The start control motor 401 is started and runs. Supported by the lifting frame 402 and the connecting seat 405, the drive gear 404 is driven to rotate via the transmission wheel 403 and the transmission belt 407. The drive gear 404 meshes with one of the transmission gear rings 406 in the middle position of the outer side of the operating disk 201. Since the four transmission gear rings 406 mesh with each other, the four operating disks 201 are driven to rotate synchronously. During the rotation of the operating disk 201, the stabilizing frame 205 and the stabilizing bar 204 fixed on the mounting frame 3 slide and engage inside the sliding groove 203, which plays a role in limiting and stabilizing the rotating operating disk 201, ensuring its smooth rotation.

[0056] As the operating panel 201 rotates, the rollers on both sides of it revolve around the cross-linked cable 1. The binding roller 206 on one side releases the binding wire 207 to tightly bind multiple branch cables together. The two polyethylene insulation tape rollers 208 on the other side release the polyethylene insulation tape 209. The two insulation tapes wrap around the outside of the cross-linked cable 1, which has been bound with the binding wire 207, in a ring-like manner, thereby achieving integrated forming of binding and insulation wrapping.

[0057] While the winding and binding are in progress, the take-up assembly 5 operates. The winding roller 502 is equipped with an automatic drive rotation structure that starts to wind up the processed cross-linked cable 1. The winding process provides a backward traction force to the cross-linked cable 1, allowing it to pass through the inside of the operating disc 201 at a uniform speed. Meanwhile, the guide cylinder 503 at the rear end ensures that the wound wire bundle travels in a straight line without deviating. The winding roller 502 can automatically adjust the winding speed to match the travel speed of the cross-linked cable 1, realizing continuous and automated binding, winding and take-up operations.
