Description

Technical Field

[0001] This invention relates to the field of winding reel technology, and more specifically to an automatic winding reel device with adjustable tightening. Background Technology

[0002] In electrical wiring and equipment cable storage, automatic cable reels are commonly used devices to achieve orderly cable winding. However, most existing automatic cable reel devices rely solely on the rotation of the turntable to directly wind the cable. During the winding process, the cable is prone to displacement and loosening due to its flexibility, making it impossible to form a tight inner layer. As the number of winding layers increases, the outer layer cables will stack and cross due to the looseness of the inner layer, ultimately resulting in a messy and disorderly overall winding.

[0003] Even those devices equipped with simple clamping structures often employ a fixed clamping force design, failing to adaptively adjust the clamping force according to the dynamic changes in the winding diameter during the winding process. If the clamping force is too small, the cable, due to its small diameter, is prone to looseness during the initial winding, leading to a messy overall winding after subsequent outer layer stacking. If the fixed clamping force is too large, while it can ensure a tight inner layer, as the number of winding layers increases and the diameter gradually enlarges, the tension of the outer layer cable will exert additional pressure on the already wound inner cable, easily causing continuous pressure damage and deformation to the inner layer cable. Therefore, an automatic winding reel device with adjustable clamping force is proposed, capable of adaptively adjusting the clamping force according to changes in the winding diameter to ensure the regularity of cable winding. Summary of the Invention

An elastic pneumatic clamp for holding the cable is provided on the mounting plate. An air pressure regulating structure is fixedly connected above the mounting plate. A toothed ring is fixedly connected to the side of the turntable assembly near the bracket. The toothed ring meshes with the air pressure regulating structure for transmission. The air pressure regulating structure is connected to the elastic pneumatic clamp through a first pipeline. When the turntable assembly winds the cable, the air pressure regulating structure draws air to gradually reduce the clamping force of the elastic pneumatic clamp. When the turntable assembly releases the cable, the air pressure regulating structure supplies air to gradually increase the clamping force of the elastic pneumatic clamp.

[0006] Specifically, the elastic pneumatic card holder includes a movable card holder with an arc-shaped groove on its surface. An opening is provided on the inner side of the arc-shaped groove, and an elastic expansion pad is installed inside the arc-shaped groove. The air outlet of the air pressure regulating structure is connected to the interior of the elastic expansion pad via a first pipeline. The air pressure regulating structure is a peristaltic pump, and a drive gear is fixedly connected to the pump shaft of the peristaltic pump. The drive gear meshes with a gear ring for transmission. The mounting plate is provided with a drive structure for driving the movable card holder to reciprocate.

[0007] Specifically, the drive structure includes a horizontally arranged reciprocating lead screw, one end of which is coaxially connected to the peristaltic pump shaft, and the other end of which is fixedly connected to the upper surface of the mounting plate via a support plate.

[0008] Specifically, the movable card holder is provided with a limiting hole, and a horizontally arranged limiting rod is slidably connected in the limiting hole. One end of the limiting rod is fixedly connected to one side of the support plate, and the other end of the limiting rod is fixedly connected to the mounting plate through a support rod.

[0009] Specifically, the turntable assembly includes a rotating drum and limiting plates fixedly connected to both ends of the rotating drum.

[0012] Specifically, both the inner sides of the first and second arc-shaped cleaning plates are detachably connected to elastic cleaning scrapers.

[0013] Specifically, a fixing ring is fixedly connected to the bracket, and a horizontally arranged mounting plate is fixedly connected to the fixing ring. The mounting plate is located on the outside of the turntable assembly. An anti-slip handle is fixedly connected to the bracket.

[0014] The beneficial effects of this invention are:

[0015] (1) The automatic winding reel device with adjustable tension described in this invention achieves dynamic adaptive adjustment by meshing the toothed ring and the air pressure regulating structure, which gradually reduces the clamping force during winding and gradually increases the clamping force during release. This ensures that the inner layer of cable is tightly wound and avoids excessive compression of the inner side by the outer layer of cable. It effectively solves the problems of messy cable winding and pressure damage in existing devices, and significantly improves the regularity of cable winding and service life.

[0016] (2) The automatic winding reel device with adjustable tension described in this invention drives the reciprocating screw through the pump shaft of the peristaltic pump, which drives the moving card seat to move horizontally and reciprocally, so as to realize the spiral uniform winding of the cable; at the same time, the gas discharged during the air pressure adjustment process is used to drive the second cleaning scraper to clean the surface impurities simultaneously when the cable is winding, so as to avoid the wear and stacking caused by impurities being trapped in the winding layer. This not only improves the storage density and regularity, but also protects the cable from pollution and wear, and extends its service life. Attached Figure Description

Detailed Implementation

[0026] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0027] In order to adaptively adjust the clamping force according to changes in the winding diameter and ensure the regularity of the cable winding, as an embodiment of the present invention, such as... Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 As shown, the present invention discloses an adjustable automatic winding reel device, comprising a bracket 1, on which a turntable assembly for winding cables is rotatably connected. A mounting plate 2 is provided on one side of the turntable assembly, and an elastic pneumatic clamp for holding the cables is provided on the mounting plate 2. A pneumatic pressure regulating structure is fixedly connected above the mounting plate 2. A toothed ring 3 is fixedly connected to the side of the turntable assembly near the bracket 1, and the toothed ring 3 engages with the pneumatic pressure regulating structure for transmission. The pneumatic pressure regulating structure is connected to the elastic pneumatic clamp via a first pipe 9. When the turntable assembly winds the cables, the pneumatic pressure regulating structure draws air to gradually reduce the clamping force of the elastic pneumatic clamp; when the turntable assembly releases the cables, the pneumatic pressure regulating structure supplies air to gradually increase the clamping force of the elastic pneumatic clamp.

[0028] When in use, the drive turntable assembly rotates in the forward direction during winding. After the cable passes through the elastic pneumatic chuck, it is wound around the turntable assembly. During this process, the turntable assembly drives the toothed ring 3 to rotate synchronously. The meshing transmission between the toothed ring 3 and the air pressure regulating structure drives the air pressure regulating structure to draw air. The air pressure regulating structure draws out the gas in the elastic pneumatic chuck through the first pipeline 9, so that the clamping force gradually decreases during the winding process.

[0029] In the initial stage of winding, the elastic pneumatic clamp maintains a large clamping force, which can firmly fix the cable and ensure that the inner layer of cable is tightly wound, avoiding initial loosening due to the flexibility of the cable itself. As the number of winding layers increases and the diameter of the cable winding gradually increases, the clamping force decreases synchronously, which can effectively prevent the tension of the outer layer of cable from causing additional compression on the already wound inner cable, preventing the inner layer of cable from being damaged or deformed by pressure, while ensuring that the winding force of each layer of cable is uniform, achieving neat winding of the cable.

[0030] When the cable needs to be released, the drive turntable assembly rotates in the opposite direction. The operator pulls the cable plug end, gradually pulling the cable out of the turntable assembly. During the release process, the turntable assembly drives the toothed ring 3 to rotate in the opposite direction, and through meshing transmission, the pneumatic pressure regulating structure switches to air supply mode, continuously supplying air to the elastic pneumatic clamp. This causes the clamping force of the elastic pneumatic clamp to gradually increase as the cable is released. The initial clamping force is relatively small, which reduces the resistance when pulling the cable out, making it easier for the operator to pull. As the cable is released, the clamping force gradually increases, which can form a stable clamp on the remaining cable wrapped on the turntable assembly, preventing the cable from rebounding, loosening, or becoming tangled due to its own flexibility or the inertia of the turntable assembly. This ensures that the cable release process is orderly and controllable, while protecting the cable from pulling damage.

[0031] To reduce frictional loss between cables and extend their service life, for example, such as Figure 5 , Figure 6 , Figure 7 As shown, the present invention further includes the following: the elastic pneumatic card holder includes a movable card holder 4, the movable card holder 4 is provided with an arc-shaped card groove 5, the inner side of the arc-shaped card groove 5 is provided with a slot 6, an elastic expansion pad 7 is installed in the arc-shaped card groove 5, and the air outlet connector 8 of the air pressure regulating structure is connected to the interior of the elastic expansion pad 7 through a first pipeline 9; the air pressure regulating structure is a peristaltic pump 10, the pump shaft 11 of the peristaltic pump 10 is fixedly connected to a drive gear 12, the drive gear 12 meshes with the gear ring 3 for transmission, and the mounting plate 2 is provided with a drive structure for driving the movable card holder 4 to reciprocate.

[0032] When in use, the turntable assembly rotates forward and drives the toothed ring 3 to rotate synchronously. The toothed ring 3 meshes with the drive gear 12 to drive the peristaltic pump 10 to start. The gas in the elastic expansion pad 7 is gradually extracted through the air outlet 8 and the first pipeline 9, causing the elastic expansion pad 7 to contract due to the decrease in air pressure. This gradually reduces the clamping force on the cable. The larger clamping force in the initial stage can fix the cable, ensuring that the inner layer of cable is tightly wound, avoiding initial looseness, and improving the winding regularity.

[0033] When the cable is released, the turntable assembly rotates in the opposite direction, causing the toothed ring 3 to rotate counterclockwise, which drives the peristaltic pump 10 to switch working modes. The peristaltic pump 10 continuously supplies air to the elastic expansion pad 7 through the air outlet 8 and the first pipeline 9, causing the elastic expansion pad 7 to expand due to the increase in air pressure, and gradually increasing the clamping force on the cable during the cable release process.

[0034] Throughout the entire process of winding or releasing the cable, the cable always passes through the arc-shaped slot 5 of the movable card holder 4. The drive structure synchronously drives the movable card holder 4 to move back and forth in the horizontal direction, causing the cable to be wound evenly on the turntable assembly in a spiral manner. The spiral winding method can avoid the stacking and crossing of cables, ensuring that the cables are arranged tightly and orderly. It can also increase the cable storage density of the turntable assembly, make full use of the storage space, reduce friction loss between cables, and extend the service life of the cables.

[0035] To improve the organization of storage, for example, such as Figure 3 , Figure 5 , Figure 6 As shown, the present invention also includes a drive structure comprising a horizontally arranged reciprocating lead screw 13, one end of which is coaxially connected to the pump shaft 11 of the peristaltic pump 10, and the other end of which is fixedly connected to the upper surface of the mounting plate 2 via a support plate 14. The movable card seat 4 is provided with a threaded hole, and the reciprocating lead screw 13 passes through the threaded hole and is threadedly connected to the threaded hole.

[0036] When the cable is wound, the turntable assembly rotates forward, which drives the gear ring 3 to mesh with the drive gear 12, driving the peristaltic pump 10 and the pump shaft 11 to rotate. The pump shaft 11 drives the reciprocating screw 13 to rotate synchronously, driving the moving chuck 4 to make a continuous and stable horizontal reciprocating motion along its axis, so that the cable is evenly wound on the drum 18, which greatly improves the neatness of the winding, ensures the radial and axial space utilization of the drum 18, increases the amount of cable winding, and the reciprocating motion does not require manual intervention, with a high degree of automation, avoiding manual adjustment errors.

[0037] When releasing the cable, the turntable assembly rotates in the opposite direction, driving the peristaltic pump 10, pump shaft 11, and reciprocating screw 13 to rotate in the opposite direction synchronously. Through threaded transmission, the moving chuck 4 is driven to make horizontal reciprocating motion in the opposite direction along the reciprocating screw 13, which forms an active guide for the cable during the release process. It guides the cable to be pulled out in an orderly manner along the reverse path of spiral winding, avoiding knotting and tangling of the cable due to its own flexibility and release inertia. At the same time, it forms a dual coordination of guidance and clamping with the clamping force adjustment of the elastic pneumatic chuck, making the cable release process as orderly and controllable as the winding process, and preventing the cable from springing back and loosening.

[0038] To ensure the stability of the movement of the movable card holder 4, for example, such as Figure 5 , Figure 6As shown, the present invention also includes a limiting hole 15 on the movable card seat 4, a horizontally arranged limiting rod 16 slidably connected in the limiting hole 15, one end of the limiting rod 16 being fixedly connected to one side of the support plate 14, and the other end of the limiting rod 16 being fixedly connected to the mounting plate 2 through a support rod 17.

[0039] During use, the reciprocating screw 13 drives the moving bracket 4 to reciprocate. The limiting rod 16 constrains the moving bracket 4 through the limiting hole 15 to prevent it from rotating in the circumferential direction. This ensures that the cable is always neatly wound in a cross-spiral pattern and will not cause pitch confusion or skewed winding due to the rotation of the bracket, thus ensuring the stability of cable winding and unwinding.

[0040] For example, such as Figure 3 As shown, the present invention also includes a turntable assembly comprising a rotating cylinder 18 and a limiting plate 19 fixedly connected to both ends of the rotating cylinder 18. A cable reel dedicated module socket assembly is provided in the middle of the rotating cylinder 18. A hub motor for driving the rotating cylinder 18 to rotate is provided inside the rotating cylinder 18. The hub motor is connected to the bracket 1. The toothed ring 3 is fixedly connected to the outer side of the limiting plate 19 near the bracket 1.

[0041] When using the cable, the hub motor inside the rotating drum 18 is started to drive the rotating drum 18 to rotate. When the rotating drum 18 rotates, the cable is wound around the rotating drum 18. The limiting plates 19 at both ends will block the cable from the axial direction to prevent the cable from falling off from both ends of the rotating drum 18 during the winding process. This ensures that the cable is always neatly wound within the range of the rotating drum 18, while limiting the maximum diameter of the winding to prevent excessive winding from causing the cable to be compressed.

[0042] When the rotating drum 18 rotates, it drives the gear ring 3 to rotate synchronously. The gear ring 3 meshes with the drive gear 12 to realize the linkage between the rotating drum 18 and the air pressure adjustment structure. No additional drive device is required, so that the clamping force adjustment, the reciprocating motion of the moving card seat 4 and other actions are carried out synchronously with the winding and releasing of the cable, further improving the convenience of cable release and winding.

[0043] To ensure cable cleanliness and prevent impurities from getting trapped between the winding layers, causing cable stacking and wear, for example, such as... Figure 5 , Figure 6As shown, the present invention further includes a first arc-shaped cleaning plate 20 fixedly connected to the upper surface of the movable card seat 4, the first arc-shaped cleaning plate 20 corresponding to the arc-shaped card slot 5, a second arc-shaped cleaning plate 21 provided on one side of the first arc-shaped cleaning plate 20, a pneumatic telescopic rod 22 fixedly connected to one side of the movable card seat 4, the output end of the pneumatic telescopic rod 22 being fixedly connected to the second arc-shaped cleaning plate 21 via a connecting rod 23, the air inlet connector 24 of the air pressure regulating structure being connected to a branch pipeline, the branch pipeline including a first connecting pipe 25 and a second connecting pipe 26, the first connecting pipe 25 being connected to the pneumatic telescopic rod 22, a pressure relief valve 27 being connected to the side of the first connecting pipe 25, and a one-way air inlet connector 28 being connected to the second connecting pipe 26.

[0044] During use, when winding the cable, the turntable assembly rotates forward, driving the peristaltic pump 10 to start. Through the air outlet structure and the first pipe 9, the gas inside the elastic expansion pad 7 is gradually extracted, causing the elastic expansion pad 7 to contract and dynamically reduce the clamping force to match the winding diameter, ensuring the inner cable is tight and the outer layer is not excessively compressed. The extracted gas is discharged into the branch pipe through the air inlet connector 24 and input into the air pressure telescopic rod 22 through the first connecting pipe 25. During this process, the pressure relief valve 27 automatically releases air and pressure, preventing excessive cleaning force from damaging the cable and ensuring the safety and stability of the cable release process. This prevents the elastic expansion pad 7 from being damaged due to excessive expansion. At the same time, the clamping force of the pneumatic telescopic rod 22 can be adjusted by adjusting the pressure relief threshold of the pressure relief valve 27. The pneumatic telescopic rod 22 is retracted by the air pressure, and the second arc-shaped cleaning plate 21 moves towards the first arc-shaped cleaning plate 20 through the connecting rod 23. Finally, the two cleaning plates are attached to the outside of the cable. During the reciprocating spiral winding process of the cable, surface dust and impurities are continuously scraped off to ensure the cleanliness of the cable and prevent impurities from being trapped between the winding layers, which would cause the cable to stack and wear. This improves the winding regularity and cable service life.

[0045] When releasing the cable, the turntable assembly rotates in the opposite direction to drive the peristaltic pump 10 to switch working modes. The peristaltic pump 10 draws air through the first connecting pipe 25 and the second connecting pipe 26. After the air pressure telescopic rod 22 releases air, it retracts and resets to its initial state. The second arc-shaped cleaning plate 21 separates from the first arc-shaped cleaning plate 20 and no longer contacts the cable surface, reducing the resistance during cable release and the wear on the second arc-shaped cleaning plate 21 and the first arc-shaped cleaning plate 20. The second connecting pipe 26 and the one-way air inlet connector 28 draw in external gas. The gas is continuously delivered to the elastic expansion pad 7 through the second connecting pipe 26, the air inlet connector 24, the air outlet connector 8 and the first pipeline 9, so that the elastic expansion pad 7 gradually expands to dynamically increase the clamping force and prevent the cable from springing back and loosening during release.

[0046] To improve device safety, for example, such as Figure 2 , Figure 4As shown, the present invention also includes a horizontal plate 29 fixedly connected to the bracket 1, a fixing knob 30 provided on one side of the horizontal plate 29, a pin 31 fixedly connected to one side of the fixing knob 30, the pin 31 passing through the horizontal plate 29 and threadedly connected to the horizontal plate 29, and a plurality of circumferentially distributed pin holes 32 provided at one end of the rotating cylinder 18 near the bracket 1, the pin 31 passing through the horizontal plate 29 and corresponding to the pin holes 32.

[0047] When in use, after the cable winding and unwinding operation is completed, the operator rotates the fixing knob 30, and uses the threaded engagement between the pin 31 and the horizontal plate 29 to drive the pin 31 to move horizontally, so that the pin 31 is inserted into the corresponding pin hole 32. This prevents the drum 18 from rotating unexpectedly due to residual cable tension, environmental vibration, or accidental contact with the hub motor, and avoids the neatly wound cable from springing back and loosening, or the cable that has been released to the specified length from being pulled out excessively and becoming tangled. This ensures the stability of the cable after winding and unwinding, and improves the safety of equipment use.

[0048] For example, the present invention further includes that the inner sides of the first arc-shaped cleaning plate 20 and the second arc-shaped cleaning plate 21 are detachably connected with elastic cleaning scrapers.

[0049] When in use, the elastic deformation characteristics of the flexible cleaning scraper can conform to the surface of cables of different diameters, adapting to the cleaning needs of multiple cable specifications and reducing cleaning dead spots caused by differences in cable diameter.

[0050] For example, such as Figure 1 , Figure 5 As shown, the present invention also includes a fixing ring 33 fixedly connected to the bracket 1, a horizontally arranged mounting plate 2 fixedly connected to the fixing ring 33, the mounting plate 2 being located on the outside of the turntable assembly; and an anti-slip handle 34 fixedly connected to the bracket 1.

[0051] During use, the mounting plate 2 is rigidly fixed to the fixing ring 33 on the bracket 1, positioning and securely installing the mounting plate 2 on the outside of the turntable assembly. This prevents the mounting plate 2 from shifting during operation, which could cause misalignment of components such as the pneumatic chuck and cleaning mechanism, thus improving the stability of equipment operation.

[0052] When the equipment is moved, the staff can hold the non-slip handle 34 on the bracket 1 to prevent it from slipping and falling off, reduce safety hazards during the handling process, and facilitate the movement of the equipment to target work scenarios such as electrical construction and cable storage, adapting to the needs of multiple scenarios for mobile use.

[0053] When using this invention, hold the anti-slip handle 34 on the bracket 1 and move the equipment to the target scene such as electrical construction or cable storage; when a winding operation is required, start the hub motor in the rotating drum 18 to drive the rotating drum 18 to rotate in the forward direction. The limiting plates 19 at both ends of the rotating drum 18 can prevent the cable from falling off from both ends. When the rotating drum 18 rotates, it drives the toothed ring 3 to rotate synchronously. Through the meshing transmission between the toothed ring 3 and the drive gear 12, the peristaltic pump 10 is started and air is drawn out. The gas in the elastic expansion pad 7 is drawn out through the first pipeline 9, so that the clamping force gradually decreases with the winding process. The larger clamping force in the initial stage can firmly fix the cable and ensure that the inner cable is tightly wound, avoiding the initial loosening due to the flexibility of the cable. The subsequent decrease in clamping force can prevent the outer cable from causing additional compression to the inner side and avoid damage and deformation of the inner cable.

[0054] When the peristaltic pump 10's pump shaft 11 rotates, it drives the coaxially connected reciprocating screw 13 to rotate synchronously. Through threaded transmission, it drives the moving bracket 4 to perform horizontal reciprocating motion along the limiting rod 16, causing the cable to be spirally and evenly wound on the rotating drum 18, improving storage density and space utilization, and reducing friction loss between cables. At the same time, the gas extracted by the peristaltic pump 10 is input into the air pressure telescopic rod 22 through the air inlet connector 24 and the first connecting pipe 25, driving the second arc-shaped cleaning plate 21 to move towards the first arc-shaped cleaning plate 20 to fit the cable. During the cable winding process, it continuously scrapes away surface dust and impurities, preventing impurities from being trapped between the winding layers, which would cause cable stacking and wear, and extend the cable's service life. The pressure relief valve 27 on the first connecting pipe 25 can automatically release air pressure to prevent excessive cleaning force from damaging the cable.

[0055] When cable release is required, the hub motor is started in reverse, driving the drum 18 to rotate in the opposite direction. The operator can then pull the cable plug end to gradually release the cable. The reverse rotation of the drum 18 drives the gear ring 3 to mesh with the drive gear 12 in the opposite direction, switching the peristaltic pump 10 to air supply mode. Air is continuously supplied to the elastic expansion pad 7 through the first pipeline 9. The clamping force gradually increases during the cable release process. The initial clamping force is small, which reduces the resistance to pulling out the cable and makes it easy to pull. The subsequent increase in clamping force can stably clamp the remaining cable and prevent the cable from rebounding or loosening due to flexibility or inertia. At the same time, the reciprocating screw 13 rotates in the opposite direction, driving the moving bracket 4 to move back and forth in the opposite direction, guiding the cable to be pulled out in an orderly manner along the reverse path of the spiral winding, avoiding knots and confusion. During cable release, the pneumatic telescopic rod 22 resets, and the second arc-shaped cleaning plate 21 separates from the first arc-shaped cleaning plate 20, reducing cable release resistance and component wear.

[0056] After the cable is unwound, rotate the fixing knob 30 on the horizontal plate 29. The drive pin 31 is inserted into the pin hole 32 at the end of the rotating drum 18 through the threaded engagement. This prevents the rotating drum 18 from rotating unexpectedly due to residual tension, vibration, or accidental motor contact. It ensures that the wound cable does not spring back and loosen, and that the released cable is not pulled out excessively, thereby improving the safety of the equipment.
