Description

Technical Field

[0001] This utility model relates to the field of wire feeding reel technology, and more specifically, to a wire feeding reel. Background Technology

[0002] Currently, almost all long-term installations are designed with concealed wiring. Concealed wiring requires threading the wire through conduits, first using a steel wire as a guide, then pulling the conductor out. The conductors used in the market are mostly BV single-core copper wire, with a standard length of 100 meters per reel. Because BV single-core copper wire is usually released from the inner coil during threading, the torsional stress generated during coiling cannot be released, causing this stress to translate into additional resistance when pulling the wire, requiring greater pulling force to complete the threading. If the wire becomes difficult to pull, the following two methods are usually used: 1. Release about 10 meters of wire from the inner coil, have two people pull from both ends on-site, straighten it, and then pull again. This can damage the wire insulation or cause the conductor to overheat later, accelerating insulation aging and reducing work efficiency; 2. During the inner coil wire release stage, workers add waste machine oil or detergent to the conduit to reduce frictional resistance, thereby reducing the force required by the pulling worker and making the pulling operation easier. However, this method has two obvious drawbacks: first, the waste oil may corrode the outer sheath of the wire; second, there is a risk of igniting the oil when the wire heats up.

[0003] Therefore, it is necessary to provide a threading and releasing reel to solve the problems existing in the prior art. Utility Model Content

[0004] The main objective of this invention is to provide a wire feeding reel that can at least solve the problems in the prior art, such as high wire feeding resistance caused by the failure to release torsional stress due to the inner coil of the wire feeding reel, easy damage to the wire insulation and aging of the wire caused by manual straightening, as well as corrosion of the wire by lubricant and potential fire hazards.

[0005] To achieve the above objectives, this utility model provides a threading and unwinding reel, comprising: a support; a central shaft disposed on the support; a threading and unwinding mechanism rotatably mounted on the central shaft for threading and unwinding; a limiting mechanism disposed on the central shaft for limiting the distance between the threading and unwinding mechanism and the support; and a deceleration mechanism disposed between the central shaft and the threading and unwinding mechanism for reducing pulling resistance and reducing rotational speed during thread unwinding.

[0006] Optionally, the support includes two brackets symmetrically arranged; wherein the first ends of the two brackets are placed on the working ground, and the second ends of the two brackets support the central axis; the second ends of the brackets are provided with grooves that match the cross-sectional dimensions of the central axis.

[0007] Optionally, the wire winding and unwinding mechanism includes: a winding shaft sleeved on the central shaft, the outer surface of the winding shaft being used for a winding plate; two sets of baffles symmetrically arranged at both ends of the winding shaft, the two sets of baffles being coaxial with the winding shaft, the two sets of baffles being used to constrain the wire on the winding shaft.

[0008] Optionally, a sealing plate is fixedly provided on each of the two end faces of the winding shaft; each sealing plate is provided with a clamping hole for cooperating with a wire winding machine.

[0009] Optionally, the winding spool is provided with a wire insertion hole, which is used to fix the wire end when initially winding the wire.

[0010] Optionally, the winding spool is made from PVC drainage pipe waste.

[0011] Optionally, the baffle is made of PVC.

[0012] Optionally, the deceleration mechanism includes two sets of deceleration bearings, each set of deceleration bearings being sleeved between the central shaft and each of the sealing plates.

[0013] Optionally, the limiting mechanism includes: two sets of retaining rings, the two sets of retaining rings being sleeved on the central shaft, and each set of retaining rings being correspondingly disposed between one of the sealing plates and one of the brackets;

[0014] The retaining ring includes a spiral structure wound around the central shaft, with a handle extending from each end of the spiral structure. When opposing forces are applied to the two handles, the spiral structure bends and deforms, increasing its diameter so as to detach from the central shaft. After the force is removed, the spiral structure elastically returns to its original shape.

[0015] This utility model discloses a wire feeding reel comprising: a support; a central shaft mounted on the support; a wire feeding mechanism rotatably mounted on the central shaft for feeding wire; a limiting mechanism mounted on the central shaft for limiting the distance between the wire feeding mechanism and the support; and a deceleration mechanism mounted between the central shaft and the wire feeding mechanism for reducing pulling resistance and reducing rotational speed during wire feeding. This deceleration mechanism enables controllable outer-circle wire feeding, allowing workers to easily control the feeding process without resorting to forceful operations such as dropping the wire, effectively maintaining the integrity of the wire sheath and conductor performance. Simultaneously, it eliminates harmful substances such as waste oil, achieving smooth wire feeding through the mechanical deceleration mechanism, improving construction efficiency and ensuring construction safety.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] like Figure 1 and Figure 2As shown, a wire feeding reel includes: a support 10; a central shaft 20 disposed on the support 10; a wire feeding mechanism 30 rotatably mounted on the central shaft 20 for feeding wire; a limiting mechanism 40 disposed on the central shaft 20 for limiting the distance between the wire feeding mechanism 30 and the support 10; and a deceleration mechanism 50 disposed between the central shaft 20 and the wire feeding mechanism 30 for reducing pulling resistance and reducing rotational speed during wire feeding.

[0023] Specifically, this cable feeding reel consists of four main parts: a support 10, a central shaft 20, a cable feeding mechanism 30, and a speed reduction mechanism 50. The support 10 provides a stable foundation for the entire device, ensuring a smooth and reliable cable feeding process. The central shaft 20 serves as the rotation axis, bearing the weight of the cable feeding mechanism 30 and maintaining its stability. The cable feeding mechanism 30 can rotate freely around the central shaft 20, enabling the storage and release of cables. The speed reduction mechanism 50 is located between the central shaft 20 and the cable feeding mechanism 30, effectively reducing the rotational speed and decreasing the tensile resistance during cable feeding.

[0024] In practical use, workers need to apply tension when releasing the cable on the outer ring. When the cable is pulled out from the outer edge of the reel, it is in the outer ring release state. Workers control the release process by intermittently applying tension. The deceleration mechanism 50 reduces the rotational speed of the reel through friction when the worker applies tension, achieving a "pull once, rotate a few times, then automatically decelerate" working mode. This avoids cable tangling and tangling caused by high-speed rotation while ensuring the continuity and controllability of the release. The deceleration mechanism 50 continuously provides stable frictional resistance, gradually reducing the release speed until it stops, allowing workers to easily control the release process.

[0025] The wire feeding reel in this application achieves controllable outer ring wire feeding through a deceleration mechanism 50, allowing workers to easily control the wire feeding process without resorting to violent operations such as dropping the wire, effectively maintaining the integrity of the wire sheath and the performance of the conductor; at the same time, it eliminates harmful substances such as waste oil, and achieves smooth wire feeding through the mechanical deceleration mechanism 50, significantly improving construction efficiency and ensuring construction safety.

[0026] In one possible implementation, the support 10 includes two brackets 11, which are symmetrically arranged; wherein the first ends of the two brackets 11 are placed on the working ground, and the second ends of the two brackets 11 support the central shaft 20; the second ends of the brackets 11 are provided with grooves that match the cross-sectional dimensions of the central shaft 20.

[0027] Specifically, two identical brackets 11 are arranged symmetrically from left to right. Their first end, the bottom, is firmly set on the working ground, while their second end, the top, jointly supports the central shaft 20, ensuring that the central shaft 20 remains horizontal at all times. This guarantees a smooth and reliable wire laying process and simplifies the installation and adjustment process. The second end of each bracket 11 has a groove matching the cross-sectional dimensions of the central shaft 20. This groove not only stably supports the central shaft 20 but also ensures accurate center positioning.

[0028] In one possible implementation, the wire winding and unwinding mechanism 30 includes: a winding shaft 31, which is sleeved on the central shaft 20, and the outer surface of the winding shaft 31 is used for winding plates; two sets of baffles 32, which are symmetrically arranged at both ends of the winding shaft 31, and are coaxial with the winding shaft 31, and are used to constrain the wire on the winding shaft 31.

[0029] Specifically, the winding shaft 31, as the main structure, can be flexibly fitted onto the central shaft 20, and its outer surface is used for winding cables. Two sets of baffles 32, coaxially arranged with the winding shaft 31, are located at both ends of the winding shaft 31, effectively constraining the cable within the range of the winding shaft 31, preventing the cable from shifting or loosening during the unwinding process. This ensures both the neat arrangement of the cable and the smooth and controllable unwinding process, while also facilitating the quick loading, unloading, and replacement of the cable.

[0030] In one possible implementation, a sealing plate 34 is fixedly provided on each of the two end faces of the winding shaft 31; each sealing plate 34 is provided with a clamping hole 33, which is used to cooperate with a wire winding machine.

[0031] Specifically, a sealing plate 34 is fixedly installed on each of the two end faces of the winding shaft 31. The clamping holes 33 on each sealing plate 34 are mainly used to cooperate with the automated operating claws of the wire winding machine. During the mass production process in the wire factory, the unloaded wire feeding mechanism 30 is first removed from the support 10 and placed on the worktable of the winding machine. At this time, the mechanical operating claws of the winding machine will accurately insert into the clamping holes 33 on the sealing plate 34 and firmly clamp the sealing plate 34 through hydraulic or pneumatic devices. Then the winding machine starts, and the drive motor drives the operating claws and the winding shaft 31 connected to them to rotate at high speed. At the same time, the wire feeding device evenly feeds the wire and tightly winds it on the outer surface of the winding shaft 31. After reaching the preset number of turns or length, the winding machine automatically stops and releases the operating claws, and the wire feeding mechanism 30 with the wire fully wound can be reinstalled on the support 10 of the wire feeding reel. This realizes the efficient production of industrialized mass winding.

[0032] In one possible implementation, the winding shaft 31 is provided with a wire insertion hole 35, which is used to fix the wire end when initially winding the wire.

[0033] Specifically, the insertion hole 35 on the axial surface of the winding shaft 31 is mainly used to quickly fix the wire end during the initial winding. When the winding operation begins, simply insert the wire end directly into this axially opened insertion hole 35. The friction between the insertion hole 35 and the wire will firmly fix the wire end, effectively preventing the wire end from slipping, loosening, or knotting in the early stages of winding. This ensures that the wire can be neatly and tightly wound on the winding shaft 31 from the fixed starting point, simplifying the operation process in the initial stage of winding, avoiding the winding mess caused by the wire end not being firmly fixed, improving winding efficiency and quality, and making the subsequent wire release process smoother and more reliable.

[0034] In one possible implementation, the winding shaft 31 is made of PVC drain pipe waste.

[0035] Specifically, by directly using industrial waste as the winding substrate, resource recycling is achieved, reducing production costs. Secondly, the PVC pipe itself has moderate hardness and a smooth inner wall, which can stably support the weight of the cable while avoiding scratching the cable insulation layer. Furthermore, the standardized pipe size ensures the versatility and interchangeability of the winding shaft 31, and PVC pipes of different diameters such as 110mm and 75mm can be adapted to different specifications of cable laying requirements.

[0036] In one possible implementation, the baffle 32 is made of PVC.

[0037] Specifically, the baffle 32 is made of PVC material, which has the characteristics of high strength, light weight, corrosion resistance and good insulation performance. It can effectively restrain the cable to prevent loose displacement, and at the same time, it is inexpensive and easy to process.

[0038] In one possible implementation, the deceleration mechanism 50 includes two sets of deceleration bearings 51, each set of deceleration bearings 51 being sleeved between the central shaft 20 and each of the sealing plates 34.

[0039] Specifically, the inner ring of the reduction bearing 51 is connected to the central shaft 20 with an interference fit, allowing for both rotational concentricity and easy assembly / disassembly. The outer ring of the bearing is embedded in the bearing housings pre-set in the side baffles 32, and is axially fixed by the platform on the inner wall of the baffles 32, keeping the outer ring relatively stationary with respect to the baffles 32. The two sets of bearings are symmetrically arranged. When the central shaft 20 rotates, the fixed outer ring continuously generates resistance torque through rolling friction, achieving a smooth and controllable deceleration effect, while also supporting quick bearing replacement to adapt to different wire diameters.

[0040] In one possible implementation, the limiting mechanism 40 includes: two sets of retaining rings 41, which are sleeved on the central shaft 20, and each set of retaining rings 41 is correspondingly disposed between a sealing plate 34 and a bracket 11;

[0041] The retaining ring 41 includes a spiral structure 411, which is wound around the central shaft 20. Each end of the spiral structure 411 extends a handle 412. When opposing forces are applied to the two handles 412, the spiral structure 411 bends and deforms, increasing its diameter so as to detach from the central shaft 20. After the force is removed, the spiral structure 411 returns to its original shape due to elasticity.

[0042] Specifically, the spiral structure 411 is made of elastic material, and the handles 412 extending at both ends control the contraction and expansion of the retaining ring 41. When the handles 412 are pulled in opposite directions, the spiral structure 411 bends and deforms under force, increasing its diameter, thus allowing it to easily detach from the central shaft 20. After releasing the handles 412, the spiral structure 411 returns to its original shape due to its elasticity and tightly grips the central shaft 20. This design not only avoids surface wear caused by direct contact between the sealing plate 34 and the bracket 11, but also controls the distance between the coiling and unwinding mechanism 30 and the support 10, preventing the cable from becoming loose or jumping out of the slot due to the coil moving during the unwinding process. This ensures that the cable is always released smoothly along the set trajectory, while avoiding additional resistance caused by contact friction, thus ensuring the smoothness of the unwinding process and the neatness of the cable.

[0043] The cable feeding reel in this application is suitable for various application scenarios:

[0044] Firstly, when purchasing in bulk, wire manufacturers can directly wind the wires onto the pre-wound spool 31 provided with the product. For wiring operations with a building area of ​​over 20,000 square meters, using this type of pre-wound spool 31 can reduce the force required during wiring, improve work efficiency, and reduce labor costs. After wiring is completed, the spool 31 can be recycled and reused, further saving costs.

[0045] Secondly, users can purchase only the two side baffles 32 of the winding spool 31 (the two side baffles 32 have 160mm, 110mm, and 75mm pipe insertion holes), and then match them with PVC drainage pipes (such as 160mm, 110mm, or 75mm diameter pipes) as the winding spool 31 according to the actual wire specifications used on site. This flexible assembly method can adapt to different specifications of wires purchased on site and meet diverse needs.

[0046] Thirdly, this cable reel can cover the cable laying needs of 2.5-16mm² wires (covering 98% of common scenarios): 2.5mm² wires are suitable for ordinary sockets and lamps; 4mm² wires are used for kitchen air conditioners; 6mm² wires are suitable for the power supply of central air conditioning outdoor units; 10mm² wires meet the power supply needs of the household and power supply; and 16mm² wires are used for high-power household and power equipment, basically covering all kinds of wiring work in homes and projects.

[0047] In addition, the inner diameter of the reduction bearing 51 of the wire threading and unloading reel can be directly mounted on a 25mm steel pipe (made from scrap material) commonly found on site, without the need for additional processing; the bracket 11 can also be made on site using locally sourced materials, further reducing the cost of use and improving practicality.

[0048] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
