Technical Field
[0001] This utility model relates to the field of electrostatic ring wrapping technology, and specifically to an electrostatic ring wrapping machine. Background Technology
[0002] An electrostatic ring wrapping machine is a device used for wrapping electrostatic rings on electrical equipment such as large transformers. It is mainly used to wrap insulating paper tape (such as pleated paper, cable paper, aluminum foil, etc.) around the surface of annular winding components (hereinafter referred to as winding rings) to form an electrostatic ring, preventing electromagnetic interference and providing insulation protection. Chinese Patent Publication No. CN209843499U discloses an electrostatic ring wrapping machine for an oil-immersed transformer, including a housing. A support plate is fixedly installed on the upper surface of the housing, and a fixing ring is rotatably installed on the front surface of the support plate. An arc-shaped block disengages from the opening, and then the ring to be wrapped is inserted... The ring-shaped material of the wrapping is placed on the fixing ring, and then the arc-shaped block is inserted into the opening and fixed by the snap-fit device, thereby increasing the stability of the arc-shaped block in the opening. The arc-shaped block is inserted into the opening, and the edge of the arc-shaped block is aligned with the edge of the fixing ring. The T-shaped cylinder is pressed so that the T-shaped rod is inserted into the two slots. Then the T-shaped rotating rod is rotated so that the snap-fit block rotates into the groove. Then the T-shaped cylinder is pushed so that the T-shaped rod is disengaged from the slot. The T-shaped cylinder is screwed into the through hole so that the T-shaped rod fits tightly against the inner wall of the T-shaped cylinder, thereby preventing the snap-fit block from rotating in the groove and increasing stability.
[0003] However, in the aforementioned prior art, the small contact area between the auxiliary wheel used to drive the winding ring and the side edge of the winding ring results in low friction, making the winding ring prone to slippage and unreliable movement, which in turn affects the processing quality of the electrostatic ring. This solution addresses this technical problem. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides an electrostatic ring wrapping machine. Two pairs of conical wheels (one and two) respectively compress and convey the sides of the winding ring. The opposing clamping action of the conical wheels increases the frictional force on the winding ring, resulting in more even force distribution on both sides of the winding ring. This makes the movement of the winding ring more stable and reliable. By adjusting the operating handle of the support assembly, the screw drives the guide wheel on the bearing block to limit the winding ring's movement, thus increasing the rotational accuracy of the winding ring and improving the processing quality of the electrostatic ring.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an electrostatic ring wrapping machine, including a support platform, and further including a wrapping mechanism and a conveying mechanism respectively disposed on the support platform. The conveying mechanism includes a disc disposed on the support platform, two clamping components symmetrically disposed on the disc, and a support component disposed on the disc. The support component is disposed between the two clamping components, and a winding ring is conveyed between the clamping components and the support component. The wrapping mechanism includes a support ring connected to the support platform, a traction ring rotatably disposed on the support ring, and a driving component for driving the traction ring to rotate. The sides of the traction ring and the support ring are both provided with through slots that allow the winding ring to pass through. A pulley is rotatably disposed on the side of the traction ring, and a wrapping tape roll for wrapping the winding ring is installed on the pulley. The wrapping tape on the wrapping tape roll wraps the winding ring into an electrostatic ring. A controller is disposed on the support platform, and the clamping components and the driving component are electrically connected to the controller.
[0006] The top side of the disc is provided with a receiving groove. The clamping assembly includes a support block 1 disposed in the receiving groove 1, a conical wheel 1 rotatably disposed on the top side of the support block 1, and two guide wheels 1 respectively vertically disposed on the support block 1. An electric cylinder is disposed on the disc. The telescopic end of the electric cylinder is provided with a support arm. A conical wheel 2 corresponding to the conical wheel 1 is rotatably disposed on the support arm. The winding ring passes between the conical wheel 1 and the conical wheel 2. A motor 1 is disposed on the bottom side of the support arm. The output end of the motor 1 is connected to the conical wheel 2. The motor 1 is electrically connected to the controller.
[0007] A pressure sensor is installed at the bottom of the first support block, and the pressure sensor is electrically connected to the controller.
[0008] The top side of the disc is provided with a receiving groove 2. The support assembly includes a bearing block 2 slidably disposed in the receiving groove 2, a conical wheel 3 rotatably disposed on the bearing block 2, and two guide wheels 2 respectively rotatably disposed on the bearing block 2. A screw rod rotatably disposed on the side of the disc and communicating with the receiving groove 2 is provided. The side of the bearing block 2 is provided with an internal thread. One end of the screw rod is threadedly connected to the bearing block 2, and the other end of the screw rod is provided with an operating handle.
[0009] The support ring has a plurality of guide groove wheels arranged on its side array, the inner side of the traction ring is rotatably arranged between the plurality of guide groove wheels, the outer side of the traction ring is provided with a toothed surface, and the drive assembly includes a second motor mounted on the support platform and a gear connected to the drive end of the second motor, the gear meshing with the toothed surface.
[0010] Compared with the prior art, the beneficial effects of this utility model are: (1) The side parts of the winding ring are squeezed and conveyed by two pairs of conical wheels one and two. The opposing clamping of conical wheels one and two increases the friction of the winding ring, and the force on both sides of the winding ring is more uniform, thus making the movement of the winding ring more stable and reliable. By adjusting the operating handle of the support component, the screw drives the guide wheel two on the bearing block two to limit the winding ring, making the rotation accuracy of the winding ring higher, thereby improving the processing quality of the electrostatic ring.
[0011] (2) By setting a pressure sensor at the bottom of the first bearing block, when the electric cylinder presses down and drives the second conical wheel to descend to press the rotating winding ring or the electrostatic ring covered with the wrapping tape, the pressure is monitored in real time. The pressure of the first and second conical wheels on the electrostatic ring is kept constant by the lifting and lowering of the electric cylinder. This ensures that the electrostatic ring is driven to rotate and also avoids damage caused by the pressure on the electrostatic ring, thereby further improving the processing quality and efficiency of the electrostatic ring.

A controller is provided on the support platform 1. The clamping component 32 and the drive component 23 are electrically connected to the controller. More specifically, the pulley 221 is provided with a damping structure to ensure that the wrapping tape on the wrapping tape roll 222 is taut and straight when it is pulled, and to prevent the wrapping tape from curling freely when wrapping the winding ring 4.
[0016] The top side of the disc 31 is provided with a receiving groove 311. The clamping assembly 32 includes a support block 321 disposed in the receiving groove 311, a conical wheel 322 rotatably disposed on the top side of the support block 321, and two guide wheels 323 respectively vertically disposed on the support block 321. An electric cylinder 325 is disposed on the disc 31. A support arm 326 is disposed at the telescopic end of the electric cylinder 325. A conical wheel 324 corresponding to the conical wheel 322 is rotatably disposed on the support arm 326. The winding ring 4 passes between the conical wheel 322 and the conical wheel 324. A motor 327 is disposed on the bottom side of the support arm 326. The output end of the motor 327 is connected to the conical wheel 324. The motor 327 is electrically connected to the controller.
[0017] A pressure sensor 328 is installed at the bottom of the support block 321, and the pressure sensor 328 is electrically connected to the controller.
[0018] The top side of the disc 31 is provided with a receiving groove 312. The support assembly 33 includes a bearing block 331 slidably disposed in the receiving groove 312, a conical wheel 332 rotatably disposed on the bearing block 331, and two guide wheels 333 rotatably disposed on the bearing block 331. A screw 334 rotatably disposed on the side of the disc 31 and communicating with the receiving groove 312 is provided. The side of the bearing block 331 is provided with an internal thread. One end of the screw 334 is threadedly connected to the bearing block 331, and the other end of the screw 334 is provided with an operating handle 335.
[0019] The side of the support ring 21 is provided with a plurality of guide groove wheels 24, the inner side of the traction ring 22 is rotatably arranged between the plurality of guide groove wheels 24, the outer side of the traction ring 22 is provided with a tooth surface 25, and the drive assembly 23 includes a motor 231 arranged on the support platform 1 and a gear 232 connected to the drive end of the motor 231, the gear 232 meshing with the tooth surface 25.
[0020] The surfaces of conical wheel 1 322, conical wheel 2 324, conical wheel 332, guide wheel 1 323, and guide wheel 2 333 are all made of rubber to facilitate the compression of the winding ring 4 and avoid damage to the static ring.
[0021] The specific working process of this utility model: In use, the winding ring 4 is first placed on the conical wheel 322 of the clamping assembly 32 and the conical wheel 332 of the support assembly 33. Then, the operating handle 335 is turned to drive the screw 334 to rotate. The screw 334 drives the bearing block 331 to expand the guide wheel 333 in the receiving groove 312, so that the inner side of the winding ring 4 is in close contact with the guide wheel 333. Then, the controller controls the electric cylinder 325 to descend. The electric cylinder 325 drives the support arm 326 to descend, so that the conical wheel 324 descends and contacts the top side of the winding ring 4 until the pressure sensor 328 senses that the pressure has reached the set value. The pressure sensor 328 sends a stop signal to the electric cylinder 325 through the controller. The electric cylinder 325 stops driving the support arm 326 to descend, indicating that the conical wheel 322 and the conical wheel 324 have pressed the winding ring 4 tightly.
[0022] The end of the wrapping tape roll 222 is fixed to the side of the winding ring 4 with tape. Then, the motor 231 is started. The motor 231 drives the traction ring 22 to rotate along the guide wheel groove on the support ring 21 through the gear 232. The wrapping tape on the wrapping tape roll 222 rotates along the pulley 221 on the traction ring 22. After the wrapping tape wraps around the winding ring 4 several times, the wrapping tape and the winding ring 4 are more firmly connected.
[0023] Then, motor 327 is started. The two motors 327 drive the two conical wheels 324 to rotate. The winding ring 4 rotates under the clamping action of the two pairs of conical wheels 322 and 324. At the same time, the traction ring 22 rotates along the winding ring 4, wrapping the bandage onto the winding ring 4 to form an electrostatic ring.
[0024] The winding ring 4 is extruded and conveyed by two pairs of conical wheels 322 and 324. The opposing clamping action of the conical wheels 322 and 324 increases the friction of the winding ring 4 and makes the force on both sides of the winding ring 4 more uniform, thus making the movement of the winding ring 4 more stable and reliable, thereby improving the processing quality of the electrostatic ring.
[0025] By adjusting the operating handle 335 of the support component 33, the screw 334 drives the guide wheel 333 on the bearing block 331 to limit the winding ring 4, thereby increasing the rotational accuracy of the winding ring 4 and improving the processing quality of the electrostatic ring.
[0026] By installing a pressure sensor 328 at the bottom of the bearing block 321, the pressure is monitored in real time when the electric cylinder 325 presses down to drive the conical wheel 324 to descend and press the rotating winding ring 4 or the electrostatic ring covered with wrapping tape. The pressure on the electrostatic ring is kept constant by raising and lowering the electric cylinder 325, which ensures that the electrostatic ring is driven to rotate and avoids damage caused by the pressure on the electrostatic ring, thus further improving the processing quality and efficiency of the electrostatic ring.
[0027] The bandage can wrap multiple layers, and the damping of the pulley 221 is adjustable to adjust the bandage tension on the winding ring. The diameter range of the electrostatic ring is wider, the operation is simple and quick, and the electrostatic ring has high efficiency and good effect.
[0028] Technical features not described in detail in this solution are based on conventional operations and general understanding of those skilled in the art, and are therefore not elaborated upon here. Technical features not described in this utility model can be implemented using existing technology, and will not be repeated here. Of course, the above description is not intended to limit this utility model, nor is it limited to the examples given above. Any changes, modifications, additions, or substitutions made by those skilled in the art within the scope of this utility model should also fall within the protection scope of this utility model.
