Description

Technical Field

[0001] This utility model belongs to the field of insulating paper processing technology, and in particular relates to a transformer insulating paper cutting device. Background Technology

[0002] Transformer insulating paper is a key material in the manufacture of power transformers. It is mainly used for insulation and isolation between windings. Its cutting accuracy and quality directly affect the insulation performance and service life of the transformer. Traditional insulating paper cutting usually relies on manual operation or simple semi-automatic equipment. Manual cutting is difficult to meet the production requirements of high precision and high efficiency, and it is labor-intensive and prone to material waste due to improper operation.

[0003] In some automated cutting devices, the insulating paper is prone to wrinkles due to uneven tension during the cutting process, which leads to cutting deviations and affects the cutting quality. In addition, manual cutting requires measuring the length section by section before cutting, which is very inconvenient, time-consuming, and results in low work efficiency. Utility Model Content

[0004] The technical problem this invention aims to solve is that insulating paper is prone to wrinkles due to uneven tension, and manual cutting requires measuring the length before cutting, which is time-consuming and inefficient.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a transformer insulation paper cutting device, comprising a base, a fixing frame fixedly connected to one top end of the base, a vertical frame fixedly connected to the top of the base adjacent to the fixing frame, a horizontal plate fixedly connected between the inner walls of the fixing frame, and an inner plate fixedly connected between the inner walls of the vertical frame, and further comprising...

[0006] The feeding assembly is mounted on a fixed frame and includes a material roller rotatably connected to the fixed frame. One end of the material roller is fixedly connected to a worm gear. A servo motor is fixedly mounted on the fixed frame, and the output end of the servo motor is fixedly connected to a worm that meshes with the worm gear.

[0007] A cutting assembly is mounted on a stand, the top of which is fixedly mounted with a cylinder perpendicular to it, the free end of which is fixedly connected to a cutting blade, and the top of the inner plate is provided with a cutting groove corresponding to the cutting blade.

[0008] Furthermore, a sliding column perpendicular to the horizontal plate slides on the horizontal plate and is symmetrically distributed from left to right. A pressure plate is fixedly connected to the lower end of the sliding column. The bottom wall of the pressure plate is provided with linearly arranged ball bearings. A spring is sleeved on the sliding column and its two ends are fixedly connected to the sliding column and the horizontal plate.

[0009] Furthermore, it also includes a straightening assembly located at the top of the base, comprising a linear guide rail fixedly mounted on the top of the base, a horizontal slider sliding on the linear guide rail, a square frame fixedly connected to the top of the slider, an electric push rod fixedly mounted at the bottom inside the square frame, and a clamping plate fixedly connected to the free end of the electric push rod.

[0010] Furthermore, limit holes are provided on both sides of the frame, and limit blocks are fixedly connected to both side walls of the clamping plate, with the ends of the limit blocks moving through the limit holes.

[0011] Furthermore, a guide strip is fixedly connected to the top of the base and is symmetrically distributed relative to the linear guide rail. The bottom of the square frame is slidably mounted on the guide strip, and rubber pads are provided on the inner top wall of the square frame and the top wall of the clamping plate.

[0012] Furthermore, the top wall of the cutting blade is fixedly connected to a limiting post, which is symmetrically distributed relative to the cylinder. The upper end of the limiting post passes through the upright and is slidably connected to it.

[0015] (2) Before cutting, pass the end of the insulating paper through the gap between the cutting knife and the inner plate, and lay it flat on the upper surface of the clamping plate. Start the electric push rod to drive the clamping plate to move up and use the rubber pad with high friction coefficient to press the end of the insulating paper to ensure that there is no slippage during the cutting process.

[0016] (3) The material roller is driven to rotate by the worm gear to achieve precise unwinding of the insulating paper. The slider on the linear guide rail is moved laterally to pull the insulating paper to the preset cutting length to ensure the cutting size accuracy.

[0025] like Figures 1-2 As shown, a transformer insulation paper cutting device includes a base 1, a fixed frame 2 fixedly connected to one top end of the base 1, a vertical frame 3 fixedly connected to the top of the base 1 adjacent to the fixed frame 2, a horizontal plate 4 fixedly connected between the inner walls of the fixed frame 2, and an inner plate 5 fixedly connected between the inner walls of the vertical frame 3. It also includes a feeding assembly, a cutting assembly, and a straightening assembly. The feeding assembly is located on the fixed frame 2, the cutting assembly is located on the vertical frame 3, and the straightening assembly is located on the top of the base 1.

[0026] like Figures 1-5 As shown, in order to facilitate the release of insulating paper and prevent loosening or deviation during unwinding, the unwinding assembly includes a material roller 6 rotatably connected to a fixed frame 2. One end of the material roller 6 is fixedly connected to a worm gear 7. A servo motor 8 is fixedly installed on the fixed frame 2. The output end of the servo motor 8 is fixedly connected to a worm gear 9 that meshes with the worm gear 7. A sliding column 13 perpendicular to the horizontal plate 4 slides on the horizontal plate 4 and is symmetrically distributed on both sides. A pressure plate 14 is fixedly connected to the lower end of the sliding column 13. The bottom wall of the pressure plate 14 is provided with linearly arranged balls 15. A spring 16 is sleeved on the sliding column 13 and its two ends are fixedly connected to the sliding column 13 and the horizontal plate 4. The material roller 6 is used to wind the insulating paper. The balls 15 at the bottom of the pressure plate 14 are always kept in contact with the surface of the insulating paper under the pre-tightening force of the spring 16 to prevent loosening or deviation during unwinding. The material roller 6 is driven to rotate by the worm gear 7 and the worm gear 9 to achieve precise unwinding of the insulating paper.

[0027] like Figures 1-3 As shown, in order to facilitate the cutting of insulating paper, a cylinder 10 perpendicular to the top of the cutting assembly frame 3 is fixedly installed. A cutting blade 11 is fixedly connected to the free end of the cylinder 10. The top of the inner plate 5 is provided with a cutting groove 12 corresponding to the cutting blade 11. A limiting post 26 is fixedly connected to the top wall of the cutting blade 11 and is symmetrically distributed relative to the cylinder 10. The upper end of the limiting post 26 passes through the frame 3 and is slidably connected to it. During cutting, the cylinder 10 drives the cutting blade 11 to move down and cooperate with the cutting groove 12 at the bottom to complete the rapid cutting of the insulating paper.

[0028] like Figures 1-5 As shown, for precise cutting length and cutting effect, the straightening assembly includes a linear guide rail 17 fixedly mounted on the top of the base 1. A horizontal slider 18 slides on the linear guide rail 17. A square frame 19 is fixedly connected to the top of the slider 18. An electric push rod 20 is fixedly mounted at the bottom inside the square frame 19. A clamping plate 21 is fixedly connected to the free end of the electric push rod 20. Limiting holes 22 are opened on both sides of the square frame 19. Limiting blocks 23 are fixedly connected to both side walls of the clamping plate 21. The ends of the limiting blocks 23 move through the limiting holes 22. A guide is fixedly connected to the top of the base 1. The guide strip 24 is symmetrically distributed with respect to the linear guide rail 17. The bottom of the frame 19 is slidably mounted on the guide strip 24. The inner top wall of the frame 19 and the top wall of the clamping plate 21 are both provided with rubber pads 25. The end of the insulating paper is passed through the gap between the cutting blade 11 and the inner plate 5 and laid flat on the upper surface of the clamping plate 21. The electric push rod 20 is activated to drive the clamping plate 21 to move upward. The rubber pads 25 with high friction coefficient are used to press the end of the insulating paper to ensure that there is no slippage during the cutting process. The slider 18 on the linear guide rail 17 is moved laterally to pull the insulating paper to adjust to the preset cutting length to ensure the cutting size accuracy.

[0029] In practical use, insulating paper can be wound around the roller 6. The ball bearings 15 at the bottom of the pressure plate 14 are always pressed against the surface of the insulating paper under the action of the spring 16 to prevent it from getting messy. When cutting the insulating paper, the end of the insulating paper is passed between the cutter 11 and the inner plate 5 and placed above the clamping plate 21. Then, the electric push rod 20 is extended to move the clamping plate 21 upward. When the clamping plate 21 moves upward, it drives the limiting block 23 to slide inside the limiting groove, ensuring the stable movement of the clamping plate 21. The friction of the rubber pad 25 is used to achieve this. The friction force clamps the end of the insulating paper. At the same time, the servo motor 8 and the control linear guide rail 17 are turned on. The material roller 6 rotates under the meshing transmission of the worm gear 9 and worm wheel 7 to release the insulating paper. The lateral sliding of the slider 18 can pull the insulating paper to adjust the cutting length. When the frame 19 slides, the guide strip 24 guides it and increases the stability of the sliding of the frame 19. Finally, the control cylinder 10 extends to make the cutting blade 11 move down. With the cooperation of the cutting groove 12, the insulating paper can be cut.
