Description

Technical Field

[0001] This invention relates to an automatic cable winding and bundling device with adjustable inner and outer diameters and its usage method, belonging to the field of cable processing technology. Background Technology

[0002] During power laying, communication cabling, equipment installation, and engineering maintenance, cables typically require coiling and bundling at the factory, during transportation, warehousing, construction transfer, and on-site handling. In environments with a wide variety of cable specifications, significant differences in cable diameter and flexibility, and frequent variations in coiling length, coiling equipment not only needs to guide, coil, and limit the cable, but also needs to adjust the coiling space dimensions according to different cable specifications and coordinate with an appropriate coiling height to ensure that the cable can stably enter the coiling area and remain neatly coiled, thereby meeting the requirements for subsequent handling, bundling, and storage.

[0003] However, the winding space in existing technologies is usually a fixed structure, which cannot be adjusted according to the diameter and coiling requirements of different cable specifications. This can easily lead to coiling that is too loose, too tight, or irregular in shape, affecting subsequent bundling and transportation. At the same time, the winding height is usually fixed, and the position of the cable needs to be manually adjusted when it enters the winding area. During the operation, cable deviation, uneven stacking, or manual cable support can easily occur, increasing labor intensity and reducing work efficiency.

[0004] Therefore, there is an urgent need for an automatic cable winding and bundling device and method with adjustable inner and outer diameters to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an automatic cable winding and bundling device and method with adjustable inner and outer diameters, which solves the problems of difficult control of cable specifications and fixed winding height.

[0006] The technical problem to be solved by this invention is achieved by the following technical solution: an automatic cable winding and bundling device with adjustable inner and outer diameters. include The machine includes a frame, a conductor unit, and a winding unit, wherein the conductor unit and the winding unit are mounted on the frame. The conductor unit is located on the inlet side of the frame and can guide the cable into the winding unit; The winding unit is mounted on the frame and is used to automatically wind the incoming cable into a coil. The winding unit includes a diameter adjustment section, a baffle plate, and a drive motor. The diameter adjustment section is located on the wire inlet side of the frame, the baffle plate is located at one end of the diameter adjustment section, and the drive motor is used to drive the diameter adjustment section to rotate. The diameter adjustment section is used to adjust the outer diameter of the winding space. The winding unit has a winding state and an open state. When it is in the winding state, the outer diameter of the diameter adjustment section increases and the baffle stands up to limit the cable coiling path. When it is in the open state, the outer diameter of the diameter adjustment section decreases and the baffle falls down to release the coiled cable for bundling or unloading.

[0007] Preferably, the diameter adjustment section includes a quadrilateral linkage mechanism, which includes at least two sets of connecting rods and at least two rotating connection points. The connecting rods move synchronously under the drive of a control motor to enable the diameter adjustment section to open or close.

[0008] Preferably, the baffle is linked to the diameter adjustment part via a tilt handle, and the tilt handle drives the baffle to switch between an upright state and a tilted state under the driving action.

[0009] Preferably, the upward movement of the tilt handle can control the baffle to stand up, and the downward movement of the tilt handle can control the baffle to fall down.

[0010] Preferably, the conductor unit includes a conductor wheel, which is disposed on the inlet side of the frame for guiding and limiting the cable.

[0011] Preferably, the outer side of the winding unit forms a winding channel for coiling the cable, the winding channel being defined by the adjusting section and the baffle.

[0012] Preferably, the output end of the drive motor is connected to the diameter adjustment part via a transmission component.

[0013] Preferably, the baffle provides an outer limit to the coiled cable in the winding state and makes way for the removal and bundling of the coiled cable in the open state.

[0014] Preferably, a height adjustment component is provided at the bottom of the frame. The height adjustment component includes a lifting motor and a lead screw. The lifting motor is located at the bottom of the frame and drives the lead screw to control the winding unit to move up and down relative to the frame, thereby adjusting the winding height of the cable.

[0015] A method of using an automatic cable winding and bundling device with adjustable inner and outer diameters, preferably, S1. According to the specifications of the cable to be wound, adjust the diameter adjustment part of the winding unit so that the outer diameter of the winding space meets the winding requirements, and adjust the winding unit to the winding state. S2. Guide the cable to be wound into the winding channel of the winding unit via the conductor unit; S3. Start the drive motor to rotate the diameter adjustment part and automatically wind the cable into a coil; S4. After winding is completed, switch the winding unit to the open state, so that the outer diameter of the adjusting part is reduced and the baffle is lowered, thereby releasing the coiled cable and completing the binding or unloading.

[0016] Preferably, in step S1, the connecting rod of the diameter adjustment part is driven to move synchronously through the quadrilateral linkage mechanism to adjust the winding space size.

[0017] Preferably, in step S1 or S4, the baffle is switched between an upright state and a down state by driving the tilt handle.

[0018] Preferably, in step S1, the height of the take-up unit relative to the frame is adjusted by adjusting the height component so that the cable enters the take-up channel in a stable path.

[0019] Preferably, in step S3, the diameter adjustment part provides tension support to the cable during rotation, so that the cable remains evenly distributed during winding.

[0020] Preferably, in step S4, the diameter adjustment section releases the radial constraint on the coiled cable during the process of reducing the outer diameter, so that the coiled cable can be completely detached from the winding unit.

[0021] The beneficial effects of this invention are: This invention, through the setting of an adjustment section and a quadrilateral linkage mechanism, enables the synchronous opening or closing of the outer diameter of the winding space of the winding unit, achieving adaptation to the coiling size of cables of different specifications. It solves the problem in existing technologies where the winding space is fixed and cannot be adjusted according to cable diameter and coiling requirements, ensuring that the cable maintains a suitable bending radius during winding, reducing situations where coiling is too loose or too tight, and resulting in irregular coil shapes, thereby improving coiling quality and the stability of subsequent binding and transportation.

[0022] This invention, by incorporating a baffle that stands upright in the winding state and falls down in the unwinding state, provides external restraint on the cable's coiling path during winding and releases space for removal after winding is complete. This ensures that cables of different specifications maintain relatively regular axial boundaries during winding, preventing them from becoming tangled due to inertia, swaying, or stacking deviations, thereby further improving the neatness of the coils and reducing the difficulty of subsequent arrangement.

[0023] This invention incorporates a height adjustment component, enabling the winding unit to move vertically and adjust its winding position based on the cable's natural height upon entering the winding area. This solves the problems of fixed winding height and the need for manual adjustment of the cable's position upon entry into the winding area. It allows the cable to enter the winding channel with a smoother path, reducing cable deviation, shaking, and uneven stacking, thus minimizing the need for manual cable handling and reducing the workload of operators.

[0028] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this invention, the invention will be further described below in conjunction with specific embodiments. Example 1

[0029] like Figures 1-3 As shown, an automatic cable winding and bundling device with adjustable inner and outer diameters includes a frame 1, a conductor unit 2, and a winding unit 3, wherein the conductor unit 2 and the winding unit 3 are mounted on the frame 1.

[0030] The conductor unit 2 is located on the inlet side of the frame 1 and can guide the cable into the winding unit 3. The winding unit 3 is located on the frame 1 and automatically winds the incoming cable into a loop.

[0031] The winding unit 3 includes a diameter adjustment section 31, a baffle plate 32, and a drive motor 33. The diameter adjustment section 31 is located on the wire inlet side of the frame 1, the baffle plate 32 is located at one end of the diameter adjustment section 31, and the drive motor 33 is used to drive the diameter adjustment section 31 to rotate.

[0032] The diameter adjustment section 31 can adjust the outer diameter of the winding space, and the winding unit 3 has a winding state and an open state. When the winding unit 3 is in the winding state, the outer diameter of the diameter adjustment section 31 increases, and the baffle 32 stands up to limit the cable coiling path; when it is in the open state, the outer diameter of the diameter adjustment section 31 decreases, and the baffle 32 falls down to release the coiled cable for bundling or unloading.

[0033] The frame 1 adopts a rectangular frame structure, which in this embodiment is welded from rectangular steel pipes, square steel, or channel steel to form a stable load-bearing skeleton. A base structure is formed at the bottom of the frame 1, on which anchor bolt holes, shock-absorbing pads, or locking casters can be provided for fixed installation or relocation of the equipment. An inlet side plate is provided on one side of the frame 1, which serves to separate the front and rear spaces of the equipment and as a mounting base. It has shaft holes, mounting holes, and inspection holes to facilitate the installation and maintenance of the conductor unit 2, winding unit 3, and transmission component 34. The working area of ​​the winding unit 3 is located on the front side of the inlet side plate, and the drive motor 33 is located on the rear side of the inlet side plate, creating an actual winding space on the front and a power transmission space on the rear. The structural partitioning is clear, facilitating protection and maintenance. In this embodiment, the space behind the inlet side plate is enclosed by the frame 1, and a removable maintenance port is provided for easy access to the interior space of the frame 1 for maintenance.

[0034] The conductor unit 2 is located on the cable inlet side of the frame 1, and the conductor unit 2 can guide the cable into the winding unit 3. The conductor unit 2 includes a conductor wheel 21 and a conductor support 22.

[0035] In this embodiment, the guide wheel 21 adopts a circular roller structure with an arc-shaped guide groove machined on its outer circumference. The width of the guide groove is slightly larger than the diameter of the cable to be wound, ensuring smooth cable passage and preventing jamming. The guide wheel 21 is internally connected to a rotating shaft via bearings. Both ends of the rotating shaft are fixed to the guide support 22, allowing the guide wheel 21 to rotate freely under the traction of the cable. The guide support 22 is fixed to the inlet side plate, and the installation height of the guide wheel 21 matches the cable entry height, ensuring that the cable, after entering from the external supply end, first passes through the guide wheel 21 before entering the winding unit 3. The guide wheel 21 guides, limits, and reduces friction on the cable, preventing it from swaying, scraping, or twisting before entering the winding area, thereby improving the neatness of subsequent winding.

[0036] In this embodiment, the wheel body of the guide wheel 21 is made of aluminum alloy, nylon coated with rubber, or stainless steel. The rubber coated wheel body is suitable for cables with softer outer sheaths, while the metal wheel core structure is suitable for heavier cables or cables with greater traction, in order to ensure load-bearing capacity and durability.

[0037] The wire support 22 adopts an L-shaped support, with one end fixedly connected to the frame 1 and the other end used to support the wire wheel 21, ensuring that the position of the wire wheel 21 is stable and reliable.

[0038] The winding unit 3 is mounted on the frame 1 and is used to automatically wind the incoming cable into a coil. The winding unit 3 includes an adjusting section 31, a baffle 32, and a drive motor 33. The adjusting section 31 is located on the cable inlet side of the frame 1, the baffle 32 is located at one end of the adjusting section 31, and the drive motor 33 is used to drive the adjusting section 31 to rotate.

[0039] In this embodiment, the drive motor 33 is a geared motor, which can increase the output torque and reduce the speed, making the cable winding process smoother. The motor body of the drive motor 33 is fixed inside the frame 1 behind the cable inlet side upright plate. The output shaft of the drive motor 33 is connected to the adjusting section 31 through a transmission component. The transmission component adopts a sprocket and chain structure, with the driving sprocket mounted on the output shaft of the drive motor 33, the driven sprocket mounted on the main shaft of the adjusting section 31, and the chain wound between the driving sprocket and the driven sprocket. The sprocket and chain drive has the advantages of stable transmission, strong impact resistance, and convenient maintenance, and is suitable for working conditions with continuous tension and instantaneous load changes during cable winding. A protective cover can be installed on the outside of the transmission component to prevent debris from getting caught in the chain and to reduce operating noise.

[0040] The adjusting section 31 is used to adjust the size of the winding space. The winding unit 3 has a winding state and an open state. In the winding state, the outer diameter of the adjusting section 31 increases, and the baffle 32 stands up to limit the cable coiling path. In the open state, the outer diameter of the adjusting section 31 decreases, and the baffle 32 falls down to release the coiled cable for bundling or unloading. The size of the winding space includes the outer and inner boundaries of the winding space. When the adjusting section 31 opens or closes, the radial range of the winding space changes accordingly, thereby adapting to the coiling requirements of different cable specifications. Thicker cables are wound through the larger winding space after opening, which can prevent excessive bending when the cable bending radius is too small; thinner cables are wound through the smaller winding space after closing, which can prevent the coiling from being too loose and the shape from being messy. Therefore, the winding unit 3 can cover a wider range of cable specifications.

[0041] In this embodiment, the diameter adjustment section 31 employs a quadrilateral linkage mechanism to achieve changes in the winding space size. The quadrilateral linkage mechanism includes two sets of connecting rods and two rotating connection points. The two sets of connecting rods are symmetrically arranged around the winding center, forming a linkage frame capable of unfolding and retracting through hinge connections. Pins, bushings, bushings, or rolling bearings are provided at the ends of the connecting rods to ensure minimal friction and sensitive response at each rotating connection point during movement. Under continuous operation, wear-resistant copper sleeves or oil-impregnated bushings can be added to the rotating parts of the connecting rods to improve their service life. After the connecting rods in the quadrilateral linkage mechanism cooperate, they can synchronously unfold outwards or retract inwards under the control of the motor, thereby changing the radial dimension of the diameter adjustment section 31.

[0042] In this embodiment, the diameter adjustment part 31 includes a cylindrical support body and a quadrilateral linkage mechanism disposed on the outer periphery of the cylindrical support body. The cylindrical support body passes through the inlet side upright plate, and the quadrilateral linkage mechanism is located on the front side of the inlet side upright plate and is used to adjust the outer diameter of the winding space.

[0043] The rear part of the inlet-side upright plate is connected to the drive motor 33 via a transmission component, and the drive motor 33 can drive the diameter adjustment section 31 to rotate. The surface of the diameter adjustment section 31 on the front side of the inlet-side upright plate is provided with multiple baffles 32 and multiple quadrilateral linkage mechanisms. The baffles 32 are located at the edges of the diameter adjustment section 31, and the quadrilateral linkage mechanisms are located in the middle. A total of 3 sets of quadrilateral linkage mechanisms and 3 sets of baffles 32 are provided. The 3 sets of quadrilateral linkage mechanisms and the 3 sets of baffles 32 are spaced at the same angles.

[0044] In this embodiment, a control motor is installed inside the cylindrical structure of the adjusting section 31. The control motor can drive the quadrilateral linkage mechanism and the baffle 32 to operate independently.

[0045] When the control motor drives the quadrilateral linkage mechanism to open, the connecting rods expand outwards synchronously. One side of the quadrilateral linkage mechanism is fixed to the outside of the cylinder of the adjusting section 31. The control motor can control the movable side opposite the fixed side. When the movable side expands outwards, the connecting rods on both sides can ensure that the movable side is parallel to the fixed side.

[0046] In this embodiment, when the three sets of quadrilateral linkage mechanisms expand outwards simultaneously, the outer diameter of the adjusting part 31 increases, the winding space expands, and the inner space after coiling increases accordingly; when the three sets of quadrilateral linkage mechanisms contract inwards simultaneously, the outer diameter of the adjusting part 31 decreases, the winding space shrinks, and the inner space after coiling decreases accordingly.

[0047] As the outer diameter of the adjusting section 31 increases, the winding space expands accordingly. When the control motor reverses and drives the quadrilateral linkage mechanism to retract, the connecting rods retract synchronously, the outer diameter of the adjusting section 31 decreases, and the winding space shrinks. Since this change is completed synchronously by multiple connecting rods, the winding space changes more evenly, and the winding center does not shift significantly, thus avoiding the eccentricity problem that is prone to occur in ordinary single-point stretching structures.

[0048] In this embodiment, the movable side of the quadrilateral linkage mechanism is set as an arc-shaped cable support surface or a rounded transition surface. The cable support surface is a continuous arc surface or an approximately circumferential surface formed by splicing multiple arc-shaped plates. This allows the cable to slide along a smoother surface during winding, reducing wear on the cable sheath. When the cable outer diameter is large or the surface is hard, an abrasion-resistant coating layer can be provided on the cable support surface. The abrasion-resistant coating layer is made of abrasion-resistant rubber, nylon, or polyurethane to improve contact comfort and durability.

[0049] The diameter adjustment section 31 adjusts the winding space size so that cables of different diameters and flexibility can be coiled under suitable radius conditions.

[0050] The baffle 32 is used to limit the axial spread width of the coiled cable. The cylindrical outer circumference of the adjusting part 31 is provided with multiple mounting holes at axial intervals. The bottom of the baffle 32 is installed in the corresponding mounting hole by a pin, thereby adjusting the limiting distance between the baffle 32 and the frame 1 according to the cable specification.

[0051] In this embodiment, the baffle 32 is provided with a connecting hole above the bottom pin. The connecting hole can be connected to the tilt handle. One end of the tilt handle is connected to the baffle 32, and the other end is set in the cylinder of the adjusting part 31 and connected to the control motor. The control motor can adjust the angle of the baffle 32 by controlling the tilt handle, so as to open or close the baffle 32.

[0052] Three baffles 32 are preferably provided on the circumference of the adjusting section 31. The three baffles 32 are evenly spaced along the circumference to ensure that the overall cable remains neatly coiled under the limiting action of the outer side of the baffles 32 when it is wound.

[0053] Since the baffle 32 of the diameter adjustment section 31 can open or close, the size of the winding channel can also change synchronously, so the equipment can adapt to the winding requirements of cables of different specifications.

[0054] The output end of the drive motor 33 is connected to the adjusting section 31 via a transmission component. The transmission component adopts a chain drive structure consisting of a drive sprocket, a driven sprocket, and a chain. The drive sprocket is mounted on the output shaft of the drive motor 33, the driven sprocket is mounted on the main shaft of the adjusting section 31, and the chain is wound between the drive sprocket and the driven sprocket. After the drive motor 33 starts, its output torque is transmitted to the adjusting section 31 via the chain, enabling the adjusting section 31 to obtain continuous rotational power.

[0055] When the adjusting section 31 rotates, the cable enters the winding channel stably under the guidance of the guide wheel 21, and is wound layer by layer as the adjusting section 31 continues to rotate, thereby forming a coil.

[0056] In this embodiment, a height adjustment assembly is provided at the bottom of the frame 1. The height adjustment assembly includes a lifting motor, a lead screw, and a lifting support. The lifting motor is fixed on a mounting base at the bottom of the frame 1, and the lead screw is arranged vertically and drivenly connected to the output end of the lifting motor. The lifting support is fixedly connected to the bottom of the winding unit 3. When the lead screw rotates, the lifting support moves up and down vertically, thereby driving the winding unit 3 to move up and down relative to the frame 1, adjusting the winding height of the cable.

[0057] By setting the height adjustment component, the height relationship between the winding unit 3 and the external cable supply point can be adjusted. Different cables may be supplied in different ways, such as cable reel feeding, cable rack feeding, ground dragging, or high-position suspension feeding, resulting in inconsistent natural heights of the cables when they enter the winding channel. Adjusting the height of the winding unit 3 using the height adjustment component 9 makes the cable's path into the winding channel smoother, reducing the need for lifting or pulling the cable upwards or downwards, minimizing cable deviation and swaying during entry, and reducing the number of times manual straightening is required.

[0058] A method for using an automatic cable winding and bundling device with adjustable inner and outer diameters includes the following steps: S1. First, adjust the outer diameter of the adjusting section 31 according to the specifications of the cable to be wound, and adjust the winding unit 3 to a suitable height through the height adjustment component 9 so that the cable is stable when it enters the winding channel.

[0059] S2. When in use, the cable is fed into the guide wheel 21 from the external cable supply end. The guide wheel 21 guides the cable so that it enters the winding channel smoothly.

[0060] S3. After starting the drive motor 33, the diameter adjustment part 31 rotates, and the cable is wound layer by layer under the rotation traction. The baffle 32 stands up to restrict the spread of the cable on the outside, so the coiling process remains stable and neat.

[0061] S4. When the cable reaches the predetermined length, predetermined number of turns, or predetermined winding weight, stop the drive motor 33, and then drive the control motor to retract the diameter adjustment part 31, while simultaneously causing the baffle 32 to fall down and release the outer limit.

[0062] At this point, the coiled cable can be directly removed from the winding unit 3 and proceed to the bundling or subsequent handling process. Since the diameter adjustment section 31 has already been coiled, there is less resistance when the coiled cable is released, and the operator does not need to forcibly pry it or disassemble it coil by coil, making the operation safer and more efficient.

[0063] In this embodiment, in step S1, the quadrilateral linkage mechanism of the diameter adjustment section 31 is driven by the motor to move synchronously, so as to adjust the winding space size.

[0064] In step S1 or S4, the baffle is switched between the upright and down states by driving the tilt handle.

[0065] In step S1, by adjusting the height of the winding unit 3 relative to the external cable supply point using the height adjustment component, the path of the cable entering the winding channel can be made smoother, reducing the cable's deviation and swaying during the entry process.

[0066] In step S3, the adjusting section 31 provides tension support to the cable during rotation, ensuring that the cable remains evenly distributed during winding.

[0067] In step S4, the diameter adjustment section 31 releases the radial constraint on the coiled cable during the process of reducing the outer diameter, so that the coiled cable can be completely removed from the winding unit.

[0068] Through the aforementioned structural coordination, this embodiment achieves functions such as automatic cable feeding, automatic winding into coils, adjustable winding space size, adjustable winding height, and automatic release after coiling. The conductor unit 2 ensures stable cable feeding, the diameter adjustment section 31 ensures compatibility with cables of different specifications, the baffle 32 ensures external limiting during winding, the height adjustment component ensures suitable cable feeding height, the drive motor 33 and transmission components ensure continuous and stable rotational action, and the quadrilateral linkage mechanism ensures uniform and symmetrical diameter adjustment. With the combined action of all components, the equipment improves coiling neatness, winding efficiency, and automation, while reducing the workload of manual handling, cable support, cable movement, and pre-binding preparation. It is suitable for use in cable processing and handling applications.

[0069] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of the invention, all of which fall within the scope of protection claimed by the present invention. The scope of protection of the present invention is defined by the appended claims and their equivalents.
