Description

Technical Field

[0001] The invention relates to the technical field of transformer insulation paper, in particular to a winding and fixing device for transformer insulation paper processing. Background Art

[0002] Transformer insulation paper is a special paper used for insulation in transformers. Its main function is to isolate the different conductive parts of the transformer, prevent the current from flowing in unexpected paths, and avoid short circuits and other faults. Between the windings of the transformer and between the windings and the core, the insulation paper can effectively block the current channel to ensure that the electric energy can be transmitted according to the designed circuit. It has high insulation resistance and can withstand higher voltages without breakdown. This is because the fiber structure inside the insulation paper and the special treatment it has undergone enable it to effectively prevent the movement of electrons. In high-voltage transformers, the insulation paper can withstand voltages of thousands of volts or even higher, ensuring that the transformer operates safely and stably at rated voltage.

The patent has the characteristics of easy disassembly of the winding drum and a dust removal mechanism.

[0004] During use, the above device clamps and fixes the automatic paper turning roller but does not achieve quick disassembly and assembly. If the automatic paper turning roller cannot be quickly disassembled and assembled, when the insulating paper is rolled up or the paper turning roller fails and needs to be replaced, it will take a long time to disassemble and install the paper turning roller, reducing the winding speed. Therefore, a winding and fixing device for transformer insulating paper processing is proposed to solve the above-mentioned problems. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a winding and fixing device for transformer insulation paper processing in view of the deficiencies in the above-mentioned prior art.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a winding and fixing device for transformer insulating paper processing, comprising a workbench, a clamping device is arranged on the top of the workbench, an anti-wrinkle device is arranged on the top of the support plate, and a compacting device is arranged on the inner wall of the anti-wrinkle device; the clamping device comprises a motor, a reciprocating screw rod, a concave plate 1, a clamping plate, an automatic paper turning roller, a concave plate 2, a connecting plate, a spring plate 1, and a support plate, the support plate is fixedly connected to the bottom of the workbench, the motor is fixedly connected to the front of the support plate, and the reciprocating screw rod is fixedly connected to the The concave plate 1 is connected to the output end of the motor, and the concave plate 1 is movably connected to the circumferential surface of the reciprocating screw rod. The clamping plate is fixedly connected to the top of the concave plate 1. When the clamping plate moves and clamps the automatic paper-turning roller, the stability of the automatic paper-turning roller during operation is ensured. The clamping and fixing of the automatic paper-turning roller enables it to be quickly disassembled and assembled. If the automatic paper-turning roller cannot be quickly disassembled and assembled, when the insulating paper is rolled up or the automatic paper-turning roller fails and needs to be replaced, it will take more time to disassemble and install the automatic paper-turning roller, reduce the winding speed, and the rear of the automatic paper-turning roller contacts the clamping plate. The concave plate 2 is movably connected to the circumferential surface of the reciprocating screw rod, the connecting plate is fixedly connected to the inner wall of the concave plate 2, the spring plate 1 is fixedly connected to the top of the connecting plate, the top of the spring plate 1 contacts the circumferential surface of the automatic paper-turning roller, the circumferential surface of the reciprocating screw rod is rotatably connected to the inner wall of the support plate, the outer wall of the concave plate 1 is slidably connected to the inner wall of the workbench, the outer wall of the concave plate 2 is slidably connected to the inner wall of the workbench, the spring plate 1 moves through internal elastic compression so that the gap between the papers shrinks during the operation of the automatic paper-turning roller, and the spring plate 1 moves When the spring plate 1 is in motion, its internal elasticity is compressed. This elastic compression generates a force, which is transmitted to the automatic paper transfer roller. Under the influence of this force, the position or state of the automatic paper transfer roller will change. Since the paper is transmitted on the automatic paper transfer roller, when the state of the automatic paper transfer roller changes, the gap between the papers will also change accordingly. Assuming that the automatic paper transfer rollers are arranged at equal intervals under normal circumstances, when the elastic compression force of spring plate 1 acts on the automatic paper transfer rollers, the distance between the paper transfer rollers may decrease, thereby shrinking the gap between the papers.

[0007] Preferably, the anti-wrinkle device includes an L-shaped plate 1, a guide plate 1, a pressure plate 1, a compression spring, a spring plate 2, and a support frame, wherein the L-shaped plate 1 is fixedly connected to the right side of the clamping plate, the guide plate 1 contacts the L-shaped plate 1, the support frame is fixedly connected to the top of the workbench, the compression spring is fixedly connected to the top of the support frame, the pressure plate 1 is fixedly connected to the top of the compression spring, and the spring plate 2 is fixedly connected to the bottom of the pressure plate 1, and the anti-wrinkle device also includes a rotating roller, a scraper 1, an elastic telescopic plate, and a scraper 2, and the rotating roller is rotatably connected to the inner side of the spring plate 2. When the rotating roller smoothes the wrinkled part of the insulating paper, it will first directly improve the surface flatness of the paper. Insulating paper is usually used in electrical equipment and other fields with high requirements for insulation performance. Its surface needs to be as flat as possible. In the manufacture of transformers, if the insulating paper has wrinkles, the coil and the insulating paper will not fit tightly when the coil is wound. The rotating roller gradually unfolds the wrinkled part by applying a certain pressure and rotating, making the surface of the insulating paper flat and smooth, which can ensure that the insulating paper can be better used during use. The invention can exert its insulation function and effectively prevent electrical equipment from malfunctioning due to poor insulation. The scraper plate 1 is fixedly connected to the bottom of the pressure plate 1, the elastic telescopic plate is fixedly connected to the top of the workbench, the scraper plate 2 is fixedly connected to the top of the elastic telescopic plate through a card plate, the outer wall of the scraper plate 2 is slidably connected to the inner wall of the support frame, the scraper plate 1 contacts the elastic telescopic plate, the circumferential surface of the rotating roller contacts the top of the support frame, the bottom of the guide plate 1 is fixedly connected to the top of the pressure plate 1, and the dust and impurities on the insulating paper are scraped off by the scraper plate 2 and the elastic telescopic plate. The main function of the insulating paper is to prevent the passage of current, and the presence of dust and impurities will reduce its insulation performance. In a high voltage environment, dust particles may form a conductive channel, causing the insulating paper to be partially punctured. After the dust and impurities on the insulating paper are scraped off, the possibility of the formation of such a conductive channel can be reduced, and the insulation resistance of the insulating paper can be effectively improved, ensuring that it can better play an insulating role in electrical equipment. For example, in the insulating layer of the transformer, clean and impurity-free insulating paper can withstand higher voltages, thereby ensuring the safe and stable operation of the transformer.

[0008] Preferably, the compacting device includes a second pressing plate, a second guide plate, a rotating rod, an upper cutting knife, an extrusion plate, a second L-shaped plate, a fixed plate, and a lower cutting knife. The second pressing plate is fixedly connected to the circumferential surface of the first spring plate, the outer wall of the second guide plate is in contact with the support frame, the rotating rod is hinged to the inner wall of the support frame through a torsion spring, and the upper cutting knife is fixedly connected to the bottom of the first pressing plate. At the same time, the second guide plate rotates to drive the lower cutting knife to move upward, and the lower cutting knife moves upward and contacts the upper cutting knife, so that the turned insulating paper is cut off. In many application scenarios, the insulating paper needs to meet specific size requirements. When the insulating paper is turned, the first pressing plate continues to Continue to move downward, the extrusion plate is fixedly connected to the circumferential surface of the compression spring, the L-shaped plate 2 is fixedly connected to the circumferential surface of the compression spring, the fixed plate is fixedly connected to the top of the support frame, the lower cutting knife is slidably connected to the inner wall of the support frame, the inner wall of the guide plate 2 is fixedly connected to the circumferential surface of the rotating rod, the bottom of the pressure plate 2 contacts the top of the guide plate 2, and the extrusion plate is driven to move downward by the compression spring, and the L-shaped plate 2 is driven to move downward by the compression spring, and the L-shaped plate 2 moves downward and contacts the fixed plate, so that the insulating paper is compacted during cutting to prevent the insulating paper from moving to the right due to tension, which is inconvenient for the next winding.

[0009] The present invention adopts the above technical solution to bring the following beneficial effects: 1. The winding and fixing device for transformer insulating paper processing cooperates with each other through the motor, reciprocating screw rod, concave plate 1, clamping plate, automatic paper turning roller, concave plate 2, connecting plate, spring plate 1, and supporting plate. When the clamping plate moves and clamps the automatic paper turning roller, the stability of the automatic paper turning roller during operation is ensured. The clamping and fixing of the automatic paper turning roller enables it to be quickly disassembled and assembled. If the automatic paper turning roller cannot be quickly disassembled and assembled, when the insulating paper is rolled up or the automatic paper turning roller fails and needs to be replaced, it will take more time to disassemble and install the automatic paper turning roller, reduce the winding speed, and the spring plate moves through internal elastic compression to make the automatic paper turning roller When the paper roller is working, the gap between the papers shrinks. When the spring plate 1 moves, its internal elasticity is compressed. This elastic compression generates a force, which is transmitted to the automatic paper transfer roller. Under the influence of this force, the position or state of the automatic paper transfer roller will change. Since the paper is transmitted on the automatic paper transfer roller, when the state of the automatic paper transfer roller changes, the gap between the papers will also change. Assuming that the automatic paper transfer rollers are arranged at equal intervals under normal circumstances, when the elastic compression force of the spring plate 1 acts on the automatic paper transfer rollers, the distance between the paper transfer rollers may decrease, thereby shrinking the gap between the papers.

[0010] 2. The winding and fixing device for transformer insulating paper processing cooperates with each other through L-shaped plate 1, guide plate 1, pressure plate 1, compression spring, spring plate 2, rotating roller, support frame, scraper 1, elastic telescopic plate and scraper 2. When the rotating roller smoothes the wrinkled part of the insulating paper, it will first directly improve the surface flatness of the paper. Insulating paper is usually used in electrical equipment and other fields with high requirements for insulation performance, and its surface needs to be as flat as possible. In the manufacture of transformers, if the insulating paper has wrinkles, it will cause the coil and the insulating paper to not fit tightly when winding the coil. The rotating roller gradually unfolds the wrinkled part by applying a certain pressure and rotating, so that the surface of the insulating paper becomes flat and smooth, which can ensure that the insulating paper is used. During use, it can better play its insulating function and effectively prevent electrical equipment from malfunctioning due to poor insulation. The dust and impurities on the insulating paper are scraped off by scraper 2 and the elastic expansion plate. The main function of the insulating paper is to prevent current from passing through, and the presence of dust and impurities will reduce its insulation performance. In a high-voltage environment, dust particles may form a conductive channel, causing partial breakdown of the insulating paper. After the dust and impurities on the insulating paper are scraped off, the possibility of the formation of such a conductive channel can be reduced, and the insulation resistance of the insulating paper can be effectively improved, ensuring that it can better play an insulating role in electrical equipment. For example, in the insulating layer of the transformer, clean and impurity-free insulating paper can withstand higher voltages, thereby ensuring the safe and stable operation of the transformer.

[0011] 3. The winding and fixing device for processing the transformer insulating paper cooperates with each other through the cooperation between the second pressing plate, the second guide plate, the rotating rod, the upper cutting knife, the extrusion plate, the second L-shaped plate, the fixed plate, and the lower cutting knife. At the same time, the second guide plate rotates to drive the lower cutting knife to move upward, and the lower cutting knife moves upward and contacts the upper cutting knife, so that the turned insulating paper is cut. In many application scenarios, the insulating paper needs to meet specific size requirements. After the insulating paper is turned, the first pressing plate continues to move downward, and the extrusion plate moves downward through the compression spring, and the L-shaped plate moves downward through the compression spring. The second L-shaped plate moves downward and contacts the fixed plate, and the insulating paper is compacted when cutting to prevent the insulating paper from moving to the right due to tension, which is inconvenient for the next winding.

When the device is started, the reciprocating screw rod 202 is driven to rotate by the motor 201, and the concave plate 1 203 is driven to move by the cross spiral groove on the reciprocating screw rod 202. 03 moves and drives the clamping plate 204 to move and clamp and fix the automatic paper turning roller 205. When the clamping plate 204 moves and clamps and fixes the automatic paper turning roller 205, the stability of the automatic paper turning roller 205 during operation is ensured. The automatic paper turning roller 205 is clamped and fixed, but it cannot be quickly disassembled and assembled. If the automatic paper turning roller 205 cannot be quickly disassembled and assembled, when the insulating paper is rolled up or the automatic paper turning roller 205 fails and needs to be replaced, it will take more time to disassemble and install the automatic paper turning roller 205, reduce the winding speed, and the automatic paper turning roller 205 has a motor inside for its own rotation drive. The rear of the automatic paper turning roller 205 contacts the clamping plate 204, and the concave plate 206 is movably connected to the reciprocating screw rod 2 02, the connecting plate 207 is fixedly connected to the inner wall of the concave plate 206, the spring plate 1 208 is fixedly connected to the top of the connecting plate 207, the top of the spring plate 1 208 contacts the circumferential surface of the automatic paper-turning roller 205, the circumferential surface of the reciprocating screw 202 is rotatably connected to the inner wall of the support plate 209, the outer wall of the concave plate 1 203 is slidably connected to the inner wall of the workbench 1, the outer wall of the concave plate 206 is slidably connected to the inner wall of the workbench 1, and at the same time, the concave plate 206 is driven to move by the cross-type spiral groove on the reciprocating screw 202, the movement of the concave plate 206 drives the connecting plate 207 to move, the movement of the connecting plate 207 drives the spring plate 1 208 to move, and the movement of the spring plate 1 208 is automatically compressed through the internal elasticity. During the operation of the paper transfer roller 205, the gap between the papers shrinks, and the internal elasticity of the spring plate 1 208 is compressed when it moves. This elastic compression generates a force, which is transmitted to the automatic paper transfer roller 205. Under the influence of this force, the position or state of the automatic paper transfer roller 205 will change. Since the papers are transferred on the automatic paper transfer roller 205, when the state of the automatic paper transfer roller 205 changes, the gap between the papers will also change. Assuming that the automatic paper transfer rollers 205 are arranged at equal intervals under normal circumstances, when the elastic compression force of the spring plate 1 208 acts on the automatic paper transfer rollers 205, the distance between the paper transfer rollers may decrease, thereby shrinking the gap between the papers.

[0016] The anti-wrinkle device 3 includes an L-shaped plate 301, a guide plate 302, a pressure plate 303, a compression spring 304, a spring plate 2 305, and a support frame 307. The L-shaped plate 301 is fixedly connected to the right side of the clamping plate 204, the guide plate 302 is in contact with the L-shaped plate 301, the support frame 307 is fixedly connected to the top of the workbench 1, the compression spring 304 is fixedly connected to the top of the support frame 307, the pressure plate 303 is fixedly connected to the top of the compression spring 304, and the spring plate 2 305 is fixedly connected to the bottom of the pressure plate 303. The anti-wrinkle device 3 also includes a rotating roller 306, a scraper 308, an elastic telescopic plate 309, and a scraper 2 310. The rotating roller 306 is rotatably connected to the inner wall of the spring plate 2 305, and is driven by the movement of the clamping plate 204. The L-shaped plate 301 moves, and when the L-shaped plate 301 moves, it contacts the guide plate 302, so that the guide plate 302 moves downward, and the guide plate 302 moves downward to drive the pressure plate 303 to move, and the pressure plate 303 moves to drive the spring plate 2 305 to move downward, and the spring plate 2 305 moves downward to drive the rotating roller 306 to move downward, and the wrinkled part on the insulating paper is smoothed by the rotating roller 306. When the rotating roller 306 smoothes the wrinkled part of the insulating paper, it will first have a direct improvement effect on the surface flatness of the paper. The insulating paper is usually used in electrical equipment and other fields with high requirements for insulation performance, and its surface needs to be as flat as possible. In the manufacture of the transformer, if the insulating paper has wrinkles, it will cause the wire to be wound when the coil is wound. The ring and the insulating paper cannot fit tightly, and the rotating roller 306 gradually unfolds the wrinkled part by applying a certain pressure and rotating, so that the surface of the insulating paper becomes flat and smooth, which can ensure that the insulating paper can better play its insulating function during use and effectively prevent electrical equipment from malfunctioning due to poor insulation. The scraper 308 is fixedly connected to the bottom of the pressure plate 303, the elastic telescopic plate 309 is fixedly connected to the top of the workbench 1, and the scraper 310 is fixedly connected to the top of the elastic telescopic plate 309 through the card plate. The outer wall of the scraper 310 is slidably connected to the inner wall of the support frame 307, the scraper 308 is in contact with the elastic telescopic plate 309, the circumferential surface of the rotating roller 306 is in contact with the top of the support frame 307, and the guide plate 302 is fixedly connected to the top of the workbench 1. The bottom is fixedly connected to the top of the pressing plate 1 303, and the movement of the pressing plate 1 303 drives the scraper 1 308 to move, and the movement of the scraper 1 308 drives the elastic expansion plate 309 to move, so that the elastic expansion plate 309 moves upward, and the upward movement of the elastic expansion plate 309 drives the scraper 2 310 to move upward, and the dust and impurities on the insulating paper are scraped off by the scraper 2 310 and the elastic expansion plate 309. The main function of the insulating paper is to prevent the passage of current, and the presence of dust and impurities will reduce its insulation performance. In a high voltage environment, dust particles may form a conductive channel, causing the insulating paper to be partially broken down. When the dust and impurities on the insulating paper are scraped off, the possibility of the formation of such a conductive channel can be reduced, and the insulation resistance of the insulating paper can be effectively improved.To ensure that it can better play the role of insulation in electrical equipment, such as in the insulation layer of the transformer, clean and impurity-free insulation paper can withstand higher voltage, thereby ensuring the safe and stable operation of the transformer. The automatic paper roller 205 has a motor inside for its own rotation drive.

[0017] Working principle: When the device is started, the reciprocating screw 202 is driven to rotate by the motor 201, and the concave plate 203 is driven to move by the cross-type spiral grooves on the reciprocating screw 202. The movement of the concave plate 203 drives the clamping plate 204 to move and clamp the automatic paper-turning roller 205. When the clamping plate 204 moves and clamps the automatic paper-turning roller 205, the stability of the automatic paper-turning roller 205 during operation is ensured. Clamping and fixing the automatic paper-turning roller 205 enables it to be quickly disassembled and assembled. If the automatic paper-turning roller 205 cannot be quickly disassembled and assembled, when the insulating paper is rolled up or the automatic paper-turning roller 205 fails and needs to be replaced, it will take more time to disassemble and install the automatic paper-turning roller 205, reducing the winding speed. The automatic paper-turning roller 205 has a built-in motor for its own rotation drive, and at the same time, the concave plate 206 is driven to move by the cross-type spiral grooves on the reciprocating screw 202. The movement of plate 206 drives the connecting plate 207 to move, and the movement of connecting plate 207 drives the spring plate 1 208 to move. The movement of spring plate 1 208 causes the gap between the papers to shrink during the operation of the automatic paper transfer roller 205 through internal elastic compression. When the spring plate 1 208 moves, its internal elasticity is compressed, and this elastic compression generates a force, which is transmitted to the automatic paper transfer roller 205. Under the influence of this force, the position or state of the automatic paper transfer roller 205 will change. Since the paper is transmitted on the automatic paper transfer roller 205, when the state of the automatic paper transfer roller 205 changes, the gap between the papers will also change accordingly. Assuming that the automatic paper transfer rollers 205 are arranged at equal intervals under normal circumstances, when the elastic compression force of the spring plate 1 208 acts on the automatic paper transfer roller 205, the distance between the paper transfer rollers may decrease, thereby shrinking the gap between the papers.

[0018] The movement of the clamping plate 204 drives the L-shaped plate 301 to move. When the L-shaped plate 301 moves, it contacts the guide plate 302, so that the guide plate 302 moves downward. The guide plate 302 moves downward to drive the pressure plate 303 to move. The pressure plate 303 moves to drive the spring plate 2 305 to move downward. The spring plate 2 305 moves downward to drive the rotating roller 306 to move downward. The wrinkled part on the insulating paper is smoothed by the rotating roller 306. When the rotating roller 306 smoothes the wrinkled part of the insulating paper, it will first have a direct improvement effect on the surface flatness of the paper. The insulating paper is usually used in electrical equipment and other fields with high requirements for insulation performance. Its surface needs to be as flat as possible. In the manufacture of transformers, if the insulating paper has wrinkles, it will cause the coil and the insulating paper to not fit tightly when winding the coil. The rotating roller 306 gradually unfolds the wrinkled part by applying a certain pressure and rotating, so that the surface of the insulating paper becomes flat and smooth, which can ensure that the insulating paper is smooth during use. The insulating paper can better play its insulating function and effectively prevent electrical equipment from malfunctioning due to poor insulation. The movement of the pressure plate 1 303 drives the scraper 1 308 to move, and the movement of the scraper 1 308 drives the elastic expansion plate 309 to move, so that the elastic expansion plate 309 moves upward, and the upward movement of the elastic expansion plate 309 drives the scraper 2 310 to move upward. The dust and impurities on the insulating paper are scraped off by the scraper 2 310 and the elastic expansion plate 309. The main function of the insulating paper is to prevent the passage of current, and the presence of dust and impurities will reduce its insulation performance. In a high voltage environment, dust particles may form a conductive channel, causing the insulating paper to be partially punctured. After the dust and impurities on the insulating paper are scraped off, the possibility of the formation of such a conductive channel can be reduced, and the insulation resistance of the insulating paper can be effectively improved, ensuring that it can better play its insulating role in electrical equipment. For example, in the insulating layer of the transformer, clean and impurity-free insulating paper can withstand higher voltages, thereby ensuring the safe and stable operation of the transformer.

When the insulating paper is turned, the pressing plate 303 continues to move downward, and the extrusion plate 405 is driven to move by the downward movement of the compression spring 304, and the L-shaped plate 406 is driven to move downward by the downward movement of the compression spring 304. The L-shaped plate 406 moves downward and contacts the fixed plate 407, and the insulating paper is compacted when cutting to prevent the insulating paper from moving to the right due to tension, which is inconvenient for the next winding.

[0020] Working principle: the spring plate 208 is extended and retracted to make the pressure plate 401 move downward, and the pressure plate 401 moves downward and contacts the guide plate 402, so that the guide plate 402 rotates, and is reset by the torsion spring of the rotating rod 403. At the same time, the rotation of the guide plate 402 drives the lower cutting knife 408 to move upward, and the lower cutting knife 408 moves upward and contacts the upper cutting knife 404, so that the rotated insulating paper is cut. In many application scenarios, the insulating paper needs to meet specific size requirements. After the insulating paper is rotated, the pressure plate 303 continues to move downward, and the compression spring 304 moves downward to drive the extrusion plate 405 to move, and the compression spring 304 moves downward to drive the L-shaped plate 406 to move downward, and the L-shaped plate 406 moves downward and contacts the fixed plate 407, so that the insulating paper is compacted during cutting to prevent the insulating paper from moving to the right due to tension, which is inconvenient for the next winding.
