Description

Technical Field

[0001] This utility model belongs to the technical field of oil-immersed transformers, specifically relating to an automatic elastic band winding and collection device. Background Technology

[0002] In modern power systems, oil-immersed transformers, as core substation equipment, undertake the critical tasks of voltage conversion and power transmission. The insulation components of oil-immersed transformers, as a crucial part of the transformer, play an indispensable role in ensuring its safe operation. Commonly used insulation components for oil-immersed transformers include shaped components, laminated components, laminated wood components, and cardboard components, etc. Common insulating components used in oil-immersed transformers include irregularly shaped components, laminated components, laminated wood components, and cardboard components. Among these, irregularly shaped components, due to their special shapes and structures, can adapt to the complex spatial layout inside the transformer, providing precise insulation protection in critical areas. Irregularly shaped components are mainly manufactured using wet paper blanks. The wet paper blank is covered with a mold as a reference, and elastic bands are used to tighten it, maintaining its stable shape on the mold.

[0003] Elastic bands are in a regular coil shape before use. However, after the production of irregularly shaped parts is completed, the removed elastic bands become twisted and tangled, unable to maintain a regular shape, making them difficult to store. Currently, storing elastic bands usually requires workers to re-coil and wind them back into a regular shape for later reuse. This manual storage process is tedious and consumes a lot of time and energy for workers, affecting production efficiency.

[0004] Therefore, how to quickly store disassembled irregular elastic bands is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an automatic elastic band winding and collecting device that addresses the shortcomings of the prior art by using a winding mechanism, a feeding mechanism and a rotating disk to quickly collect irregular elastic bands to be collected.

[0006] The present invention adopts the following technical solution: an automatic elastic band winding and collecting device, including a device support, wherein a winding mechanism, a feeding mechanism and a rotating disk are arranged sequentially and at intervals along the horizontal direction of the device support; The winding mechanism includes a winding motor, a winding shaft, and a limiting mechanism. The axis of the winding shaft extends longitudinally. The winding motor drives the winding shaft to rotate. The winding shaft is provided with an installation position for installing the elastic band. The limiting mechanism is used to limit the elastic band longitudinally. The feeding mechanism includes a feeding bracket with feeding rollers on it. The feeding rollers are arranged longitudinally to correspond to the mounting position, and the height of the feeding rollers is higher than the mounting position and the rotating disk. The rotation axis of the rotating disk extends vertically, and the rotating disk is used to place the elastic band. The elastic band on the rotating disk passes around the feeding rollers and is arranged on the mounting position.

[0007] Preferably, the limiting mechanism includes a back plate mounted on the winding shaft to prevent rotation, the back plate being arranged on the side of the mounting position facing the winding motor.

[0008] Preferably, the mounting position is a slot formed longitudinally on the winding shaft, the outer longitudinal side of the slot extends to the outer end face of the winding shaft, the inner longitudinal side of the slot extends to the back plate, and the width of the slot is adapted to the thickness of the elastic band.

[0009] Preferably, a pressing mechanism is provided on the side of the winding mechanism facing away from the feeding mechanism. The pressing mechanism includes a pressing bracket and a pressing frame. The pressing frame is arranged longitudinally corresponding to the installation position. The two transverse ends of the pressing frame are a hinge end and a pressing end, respectively. The hinge end is hinged to the pressing bracket, and the pressing end extends to the top of the installation position. The limiting mechanism also includes a limiting plate disposed on the radially outer side of the pressing end.

[0010] Preferably, the height of the hinge end is higher than the height of the pressing end.

[0011] Preferably, the feeding bracket has two feeding rollers spaced laterally on its side, and the two feeding rollers are staggered vertically.

[0012] Preferably, the height of the feed roller facing the rotating disk is higher than the height of the other feed roller.

[0013] Preferably, the feeding rollers facing the rotating disk are arranged above the rotating disk.

[0014] Preferably, the lower end of the rotating disk is provided with a rotating bracket, and the rotating disk is rotatably mounted on the equipment bracket via the rotating bracket.

[0015] Preferably, at least two limiting rods are arranged in a circumferential array at the upper end of the rotating disk along its rotation axis, and a placement frame is sandwiched between the limiting rods. The placement frame is used to hold the relaxation strap.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: The feeding roller is higher than the mounting position and the rotating disk. Utilizing this height difference, the elastic band is drawn out from the rotating disk and spread out as much as possible, making it easier for the feeding roller to level it and then neatly wind it onto the winding shaft, improving the winding and collection effect. The mounting position and the feeding roller are arranged longitudinally correspondingly, both on the same plane, facilitating a smooth transition of the elastic band to the mounting position for winding. A limiting mechanism is used to longitudinally limit the elastic band, preventing it from deviating longitudinally during winding and ensuring that the elastic band is wound into a regular coil shape.

[0017] The elastic band to be collected may be spirally wound, and different segments of the elastic band may exhibit different directions of rotation. A rotating disk is set up. The elastic band to be collected is first placed on the rotating disk, and then introduced into the feeding mechanism and winding mechanism. During the winding process, according to the direction of rotation of the elastic band, the rotating disk is rotated in the opposite direction, causing the elastic band to rotate in the opposite direction, unwinding the elastic band, and performing a pre-flattening treatment on the elastic band. This prevents the spiral elastic band from being fed into the feeding roller, which would cause flattening failure, and improves the subsequent winding and collection effect.

[0018] Furthermore, the back plate can be used to limit the longitudinal inward movement of the elastic band, preventing it from shifting or deviating during the winding process. At the same time, the mounting position is located on the side of the back plate facing away from the winding motor, making it easy to remove the elastic band after winding and storage.

[0019] Furthermore, the width of the slot is adapted to the thickness of the elastic band. The slot engages with the end of the elastic band, facilitating subsequent winding. The radially inner side of the slot extends to the back plate, allowing the back plate to restrict the axial inward movement of the elastic band. The radially outer side of the slot extends to the axially outer end face of the winding shaft. After winding and storing, the elastic band can be removed from the installation position along the slot, making it easy to remove the elastic band.

[0020] Furthermore, the hinged end of the pressure frame is hinged to the pressure bracket, extending above the mounting position. The pressure frame is longitudinally aligned with the mounting position. During winding, as the winding size of the elastic band changes, the hinged connection adapts to the dimensional deformation of the elastic band, ensuring that the pressure end always presses against the elastic band, preventing it from loosening and ensuring a tight winding. Simultaneously, the limiting plate rotates with the pressure frame, constantly limiting the longitudinal outer edge of the elastic band. Combined with the back plate, this ensures the elastic band forms a regular disc shape after winding.

[0021] Furthermore, the height of the hinge end is higher than that of the pressure end. During the winding process, the pressure end can always apply pressure to the elastic band to ensure that the elastic band is tightly wound and stored.

[0022] Furthermore, by setting two staggered feeding rollers, the elastic band can be leveled twice during the feeding process, improving the leveling effect.

[0023] Furthermore, along the direction toward the winding mechanism, the height of the two feeding rollers relative to the mounting position decreases sequentially, ensuring a flat surface while facilitating material feeding.

[0024] Furthermore, a rotating support is provided to facilitate the rotation of the rotating disk.

[0025] Furthermore, the limiting rod facilitates the placement of the storage frame, and the storage frame facilitates the transport of the elastic band to be stored.

[0026] In summary, the automatic elastic band winding and collecting device of this utility model can automatically wind and form irregular elastic bands. During the winding process, a limiting mechanism is used to prevent longitudinal movement of the elastic band during winding, which would cause deformation of the wound elastic band. A rotating disk is used to adapt to the rotation direction of the irregular elastic band, which facilitates the feeding and leveling of the subsequent feeding mechanism. This ensures that the elastic band can be organized and wound into a regular disc shape for easy reuse. No manual winding is required during the winding process, reducing the intensity of manual labor and improving production efficiency.

[0038] This utility model provides an automatic elastic band winding and collecting device, which can automatically wind and form irregular elastic bands 7. During the winding process, a limiting mechanism is used to prevent the elastic band 7 from moving longitudinally during winding and winding, which would cause deformation of the wound elastic band 7. The rotating disk 4 is used to adapt to the rotation direction of the irregular elastic band 7, which facilitates the feeding and leveling of the subsequent feeding mechanism 3. This ensures that the elastic band 7 can be sorted and wound into a regular disc shape for easy reuse. The winding process does not require manual winding and winding, reducing the intensity of manual labor and improving production efficiency.

[0039] In this embodiment, as Figure 1As shown, the spacing between the winding mechanism 2 and the feeding mechanism 3 is longitudinal, as... Figure 2 As shown, the axial direction of the winding shaft 23 is longitudinal.

[0040] Please see Figures 1 to 12 As shown, this utility model discloses an automatic elastic band winding and collecting device (hereinafter referred to as the automatic winding and collecting device), which includes a device support 1. The upper end of the device support 1 is a working plane, and multiple support legs are provided at the lower end of the working plane. The support legs are reliably supported on the ground by support feet 101. The upper end of the support feet 101 is screwed into the support legs by screws, thereby adjusting the flatness of the working plane.

[0041] In this embodiment, the working plane of the equipment support 1 is provided with a winding mechanism 2, a feeding mechanism 3 and a rotating disk 4 arranged sequentially and at intervals along the horizontal direction.

[0042] Specifically, the winding mechanism 2 includes a winding support 21, a winding motor 22, a winding shaft 23, and a limiting mechanism. The winding support 21 is as follows: Figure 10 The trapezoidal support shown is for reference. Figure 2 , 9 10, 11. A motor frame 27 is fixedly installed on the longitudinal inner side of the trapezoidal bracket, and the winding motor 22 is fixedly installed on the trapezoidal bracket through the motor frame 27. The rotation axis of the motor shaft of the winding motor 22 extends longitudinally, and the winding shaft 23 is engaged with the motor shaft through a pin to prevent rotation. The rotation axis of the winding shaft 23 is arranged coaxially with the motor shaft.

[0043] Referring to Figures 7 and 8, a bearing seat 26 is provided at the upper end of the winding bracket 21 corresponding to the position of the winding shaft 23. The winding shaft 23 is rotatably mounted on the winding bracket 21 via the bearing seat 26. In this embodiment, the outer end of the winding shaft 23 extends longitudinally out of the winding bracket 21, and a mounting position for mounting the elastic band 7 is provided at this end. A limiting mechanism is used to limit the longitudinal movement of the elastic band 7. During storage, the end of the elastic band 7 is first placed in the mounting position, and then the winding motor 22 is started to drive the winding shaft 23 to rotate, winding the elastic band 7 onto the winding shaft 23 for storage, while the limiting mechanism maintains the wound shape.

[0044] In this embodiment, the feeding mechanism 3 includes a feeding bracket 31, on which a feeding roller 32 is provided. The feeding roller 32 is arranged longitudinally corresponding to the mounting position, and the height of the feeding roller 32 is higher than the mounting position and the rotating disk 4.

[0045] The rotating disc 4 is rotatably mounted on the equipment bracket 1. The rotating disc 4 is used to hold the irregular elastic bands 7 to be stored and to drive the elastic bands 7 to rotate. Before starting the equipment, the elastic bands 7 on the rotating disc 4 are first wrapped around the feeding roller 32 and placed in the mounting position, and then wound.

[0046] In the above configuration, the height of the feeding roller 32 is higher than that of the mounting position and the rotating disk 4. Utilizing this height difference, the elastic band 7 is extended as much as possible after being drawn from the rotating disk 4, making it easier for it to be leveled by the feeding roller 32 and neatly wound onto the winding shaft 23, thus improving the winding and collection effect. The mounting position and the feeding roller 32 are arranged longitudinally and are on the same plane, facilitating a smooth transition of the elastic band 7 to the mounting position for winding. The limiting mechanism limits the longitudinal movement of the elastic band 7, preventing it from deviating longitudinally during winding, ensuring that the elastic band 7 is wound into a regular disc shape.

[0047] The elastic band 7, awaiting collection, may be spirally wound, and different segments of the elastic band 7 may exhibit different directions of rotation. A rotating disk 4 is provided. The elastic band to be collected is first placed on the rotating disk 4, and then introduced into the feeding mechanism 3 and the winding mechanism 2. During the winding process, according to the direction of rotation of the elastic band 7, the rotating disk 4 is rotated in the opposite direction, causing the elastic band 7 to rotate in the opposite direction, unwinding the elastic band 7, and performing pre-flattening treatment on the elastic band 7. This prevents the spiral-shaped elastic band 7 from being fed into the feeding roller 32, which would cause flattening failure and improve the subsequent winding and collection effect.

[0048] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0049] Please see Figures 1 to 12 As shown, in the present invention, an automatic elastic band winding and collecting device (hereinafter referred to as automatic winding and collecting device), the limiting mechanism includes a back plate 24 mounted on the winding shaft 23 to prevent rotation, and the back plate 24 is arranged on the side of the mounting position facing the winding motor 22.

[0050] Specifically, in this embodiment, such as Figure 6As shown, the mounting position is a slot 28 longitudinally formed on the winding shaft 23. The outer longitudinal side of the slot 28 extends to the outer end face of the winding shaft 23, and the inner longitudinal side of the slot 28 extends to the back plate 24. The width of the slot 28 is adapted to the thickness of the elastic band 7. The slot 28 engages with the end of the elastic band 7, facilitating subsequent winding. The inner radial side of the slot 28 extends to the back plate 24, allowing the back plate 24 to restrict the axial inward movement of the elastic band 7. The outer radial side of the slot 28 extends to the outer axial end face of the winding shaft 23. After winding and storing, the elastic band 7 can be removed from the mounting position along the slot 28, making it easy to remove the elastic band 7.

[0051] In other embodiments, the winding shaft 23 may not have a slot 28. In this case, the position where the winding shaft 23 protrudes from the winding bracket 21 is the installation position. In this embodiment, the end of the elastic band 7 to be stored is fixedly connected with a rubber sleeve. By putting the rubber sleeve on the winding shaft 23, the assembly of the elastic band 7 and the winding shaft 23 is achieved.

[0052] In this embodiment, as Figure 3 , 4 As shown in Figures 5 and 6, a fixing plate 29 is fixedly installed on the circumference of the winding shaft 23 at the position corresponding to the longitudinal inner end of the slot 28. Multiple fixing holes 291 are arranged circumferentially along the axis of the winding shaft 23 on the fixing plate 29, as shown in Figures 6 and 7. Figure 3 As shown, there are 6 fixing holes 291. Of course, in other embodiments, the number of fixing holes 291 can be set according to actual needs, such as 3, 4, etc.

[0053] The back plate 24 has a through hole at its center that matches the winding shaft 23. A fixing cavity 241, matching the fixing plate 29, is located on the side of the back plate 24 facing the slot 28. Threaded mounting holes, corresponding one-to-one with the fixing holes 291, are provided on the inner end face of the fixing cavity 241. During installation, the back plate 24 passes through the through hole into the winding shaft 23 from the rear side until the fixing plate 29 and the fixing cavity 241 are engaged. The threaded mounting holes are then aligned with the fixing holes 291, and a fixing bolt 6 is inserted into the fixing hole 291. The fixing bolt 6 is screwed into the threaded mounting hole, completing the anti-rotation installation of the back plate 24 and the winding shaft 23. This design ensures anti-rotation installation of the back plate 24 and the winding shaft 23 while facilitating assembly. Of course, in other embodiments, an anti-rotation key can also be used to achieve the anti-rotation engagement between the back plate 24 and the winding shaft 23.

[0054] Preferably, in this embodiment, a pressing mechanism 5 is provided on the side of the winding mechanism 2 facing away from the feeding mechanism 3 in the transverse direction. The pressing mechanism 5 includes a pressing bracket 51 and a pressing frame 52, and the pressing frame 52 is arranged longitudinally corresponding to the mounting position. The two transverse ends of the pressing frame 52 are a hinge end and a pressing end, respectively, wherein the hinge end is hinged to the pressing bracket 51, and the pressing end extends above the mounting position. The limiting mechanism also includes a limiting plate 25 disposed radially outside the pressing end, and the distance between the limiting plate 25 and the back plate 24 is adapted to the width of the elastic band 7.

[0055] The hinged end of the pressure frame 52 is hinged to the pressure bracket 51, and the pressure end extends above the installation position. The pressure frame 52 is arranged longitudinally corresponding to the installation position. During winding, as the winding size of the elastic band 7 changes, the hinged connection can adapt to the dimensional deformation of the elastic band 7, ensuring that the pressure end always presses against the elastic band 7, preventing the elastic band 7 from loosening during winding and ensuring that the elastic band 7 is wound tightly. At the same time, the limiting plate 25 can rotate with the pressure frame 52. The distance between the limiting plate 25 and the back plate 24 is adapted to the width of the elastic band 7. The limiting plate 25 always limits the longitudinal outer side of the elastic band 7, and together with the back plate 24, ensures that the elastic band 7 is in a regular disc shape after winding.

[0056] Of course, in other embodiments, the limiting plate 25 can also be an outer plate installed on the outside of the winding shaft 23 to stop rotation. The gap between the outer plate and the back plate 24 is adapted to the width of the elastic band 7. The outer plate limits the longitudinal outer side of the elastic band 7 to maintain the regular disc shape of the wound elastic band 7.

[0057] Specifically, in this embodiment, the pressure bracket 51 is a vertical bracket, and the hinged end is hinged to the upper end of the pressure bracket 51. The pressure bracket 52 extends diagonally downwards in an overall manner, so that the height of the hinged end is higher than the height of the pressure end. This ensures that during the winding process, the pressure end can always apply pressure to the elastic band 7, ensuring that the elastic band 7 is tightly wound and stored.

[0058] Preferably, in this embodiment, two feeding rollers 32 are arranged at a horizontal interval on the feeding bracket 31, and the two feeding rollers 32 are staggered vertically. The staggered arrangement of the two feeding rollers 32 allows for two leveling operations on the elastic band 7 during the feeding process, improving the leveling effect. Specifically, as... Figure 1 As shown, in the horizontal direction, the height of the feeding roller 32 facing the rotating disk 4 is higher than the height of the other feeding roller 32. Along the direction towards the winding mechanism 2, the height of the two feeding rollers 32 relative to the mounting position decreases sequentially, ensuring a flat surface while facilitating feeding.

[0059] In this embodiment, as Figure 1As shown, the feeding bracket 31 includes a vertical frame and a horizontal bracket 33 extending from the upper end of the vertical frame away from the winding mechanism 2. An oblique support frame is provided between the horizontal bracket 33 and the frame. Two feeding rollers 32 are provided, one of which is rotatably mounted on the vertical frame and the other is rotatably mounted on the horizontal bracket 33, and the rotation axes of the two feeding rollers 32 extend longitudinally.

[0060] In other embodiments, the number of feeding rollers 32 can be set according to actual needs when meeting practical usage requirements. For example, one feeding roller 32 can be set, or three feeding rollers 32 can be set with their vertical heights staggered. In other embodiments, the height of the feeding roller 32 facing the winding mechanism 2 can be adjusted according to actual tensioning and flatness requirements, and the height of the other feeding roller 32 can be adjusted accordingly.

[0061] In this embodiment, as Figure 1 , 12 As shown, of the two feeding rollers 32, the one facing the rotating disk 4 is positioned above the rotating disk 4. This allows for easy adjustment of the tension direction via the rotating disk 4 during use.

[0062] In this embodiment, as Figure 1 As shown, a rotating bracket 41 is provided at the lower end of the rotating disk 4. The rotating disk 4 is rotatably mounted on the equipment bracket 1 via the rotating bracket 41. Two limiting rods 42 are symmetrically arranged at the upper end of the rotating disk 4 along its rotation center. A placement frame 43 is detachably clamped between the two limiting rods 42. The placement frame 43 is used to hold the uncollected elastic band 7. In use, the uncollected elastic band 7 is first placed into the placement frame 43, and then one end of the elastic band 7 is pulled upward through the feeding mechanism 3 and placed in the mounting position of the winding mechanism 2.

[0063] In other embodiments, the upper end of the rotating disk 4 may be arranged with three limiting rods 42 arranged circumferentially along its rotation axis to accommodate the mounting frame 43. In other embodiments, the number of limiting rods 42 may also be four, six, etc., arranged circumferentially.

[0064] In this embodiment, the worker observes the spiral direction of the elastic band 7 and manually rotates the rotating disk 4 in the opposite direction to untie the elastic band 7 for pre-leveling. In other embodiments, a monitoring camera can be arranged above the mounting frame 43 to monitor the spiral direction of the elastic band 7. A rotating motor is installed on the rotating bracket 41 to drive the rotating disk 4 to rotate. Based on the monitoring information from the monitoring camera, the rotating motor drives the rotating disk 4 to automatically rotate in the opposite direction to untie the elastic band 7, thereby improving the level of automation.

[0065] The usage process of this utility model's automatic elastic band winding and collection device is as follows: like Figure 12As shown, the staff first placed the uncollected elastic band 7 into the placement frame 43, and then installed the placement frame 43 onto the rotating plate 4.

[0066] The end of the elastic band 7 is pulled upwards and passed through the two feeding rollers 32 in sequence, and the end is locked in the slot 28 of the winding shaft 23, so that the longitudinal inner side of the elastic band 7 abuts against the back plate 24, which limits its position. The pressure frame 52 is rotated so that it overlaps the elastic band 7, and the longitudinal inner side of the limiting plate 25 aligns with the longitudinal outer side of the elastic band 7, which limits the outer side of the elastic band 7.

[0067] Start the winding motor 22, which drives the winding shaft 23 to rotate. The elastic band 7 is gradually wound and rolled onto the winding shaft 23. During the winding process, the staff observes the spiral direction of the elastic band 7 in the placement frame 43 in real time and rotates the turntable 4 in the opposite direction to pre-flatten the elastic band 7. The pre-flattened elastic band 7 is then flattened by the two feeding rollers 32 and gradually transported to the winding mechanism 2 to complete the winding.

[0068] In summary, the automatic elastic band winding and collecting device of this utility model can automatically wind and form irregular elastic bands 7. During the winding process, the limiting mechanism is used to prevent the elastic band 7 from deforming due to longitudinal movement during winding. The rotating disk 4 is used to adapt to the rotation direction of the irregular elastic band 7, which facilitates the feeding and leveling of the subsequent feeding mechanism 3. This ensures that the elastic band 7 can be organized and wound into a regular disc shape for easy reuse. The winding process does not require manual winding, reducing the intensity of manual labor and improving production efficiency.

Any modifications made to the technical solution based on the technical concept proposed in this utility model shall fall within the scope of protection of the claims of this utility model.
