Description

Technical Field

[0001] This utility model relates to the field of power system equipment technology, and in particular to a device for winding insulating paper for winding skeleton. Background Technology

[0002] In power system devices such as instrument transformers, discharge coils, and reactors, the winding coils are wound on a winding frame to enhance insulation performance, such as... Figure 1 As shown, multiple layers of insulating paper are wound around the cylindrical winding frame. Several flanged slots are spaced along both ends of the insulating paper along the axial direction of the winding frame, allowing the ends of the insulating paper to be folded outwards to form insulating portions on both sides of the winding coil along the axial direction of the winding frame. In existing technology, the operation of winding the insulating paper onto the winding frame is mostly done manually. The basic process is as follows: First, flanged slots are cut on both sides of the insulating paper drawn from the roll and cut to the required length. Then, workers stack several sheets (usually more than 5 sheets) and wind them onto the winding frame for fixation. Depending on the required thickness of the insulating paper, the winding process is repeated to obtain a winding frame with insulating paper. This winding method has high labor costs and low efficiency. Furthermore, when flanged at the sides of the insulating paper, because the flanged slots of the multiple layers of insulating paper are aligned, the flanged insulating portion will have a relatively obvious gap, which has a certain impact on the insulation performance of this insulating portion. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide an insulating paper winding device for winding skeletons to solve the above problems.

[0004] For the purposes described above, this utility model provides:

[0005] A winding device for insulating paper winding of a winding frame includes a frame on which a material roll rack, a grooving mechanism and a traction mechanism are sequentially arranged.

[0006] The grooving mechanism includes a support roller and a cutting roller. The support roller is rotatably mounted on the frame and driven by a first motor. The cutting roller is rotatably mounted on the frame and aligned vertically with the support roller. Several cutters are arranged in a circular array along the axis of the cutting roller on each of the two peripheral sides of the cutting roller. A transmission sleeve made of foam material is provided on the outer sleeve of the cutting roller. Several hollow slots corresponding to several cutters are opened at both ends of the transmission sleeve so that the cutters are kept in the hollow slots. The transmission sleeve and the support roller are in close contact with the upper and lower surfaces of the insulating paper passing between them.

[0007] The traction mechanism includes a traction shaft, which is rotatably mounted on the frame and connected to a second motor via a drive.

[0008] Preferably, the frame is vertically slidably provided with two adjusting sliders located at both ends of the cutting roller, and both ends of the cutting roller are rotatably mounted on the two adjusting sliders. Adjusting screws that are screwed to the frame are rotatably mounted on the adjusting sliders.

[0009] Preferably, a fixed clamping plate is fixedly provided on the traction shaft, and a movable clamping plate opposite to the fixed clamping plate is detachably connected to the end of the traction shaft. A support rod for radial positioning of the limiting block is fixedly provided on the movable clamping plate, and the limiting block is detachably connected to the frame.

[0010] Preferably, the cutter has a T-shaped mounting portion, and the circumferential side of the cutting roller has a plurality of mounting grooves that correspond one-to-one with the plurality of hollow grooves and match the mounting portion. The mounting grooves pass through the cutting roller along the axial direction of the cutting roller to the end of the cutting roller. The mounting portion passes through the opening of the mounting groove into the mounting groove. Each end of the cutting roller is detachably connected to a mounting plate that closes the opening of the mounting groove. The mounting plates are rotatably mounted on the frame.

[0011] Preferably, a number of guide rods are provided between the material roll frame and the grooving mechanism, and between the grooving mechanism and the traction mechanism.

[0012] Preferably, the guide rod is provided with two width-limiting blocks that are spaced apart along the axial direction of the guide rod.

[0013] Preferably, a swing arm is oscillating on the frame, an angle displacement sensor is provided at the end of the swing arm, an abutment wheel is provided on the input shaft of the angle displacement sensor, and a tension spring is provided on the frame to act on the swing arm. The abutment wheel abuts against one of the guide rods as the swing arm swings under the action of the tension spring.

[0014] The beneficial effects of this utility model are as follows: By cooperating with the cutting mechanism and the traction mechanism, the operation of flanging, grooving and winding of insulating paper can be realized in a streamlined manner, saving labor and improving production efficiency. Furthermore, since the insulating paper is continuously wound on the winding frame, as the outer diameter increases, the flanging and grooving of the inner and outer layers of insulating paper are staggered in the radial direction of the winding frame, so that the insulation parts formed by subsequent folding are interlaced to eliminate gaps and ensure the overall insulation performance of the winding frame.

[0026] like Figures 2-6 As shown, an insulating paper winding device for a winding frame includes a frame 1, on which a material roll frame 2, a grooving mechanism 3 and a traction mechanism 4 are sequentially arranged along the insulating paper conveying direction;

[0027] The roll holder 2 is used to hold rolls of insulating paper;

[0028] The grooving mechanism 3 is used to cut flanges at both ends of the insulating paper during transport. Its specific structure includes a support roller 31 and a cutting roller 32. The support roller 31 is rotatably mounted on the frame 1 and is connected to the first motor 33 for transmission. The cutting roller 32 is rotatably mounted on the frame 1 and is vertically aligned with the support roller 31. Several cutters 34 are arranged in a circular array along the axis of the cutting roller 32 on the peripheral side of each end of the cutting roller 32. The length direction of the cutters 34 is parallel to the axial direction of the cutting roller 32. The cutting roller 32 is covered with a transmission sleeve 35 made of foam material. Several hollow grooves 351 are opened at both ends of the transmission sleeve 35, which correspond one-to-one with several cutters 34, so that the cutters 34 are kept in the hollow grooves 351. The transmission sleeve 35 and the support roller 31 are in close contact with the upper and lower surfaces of the insulating paper passing between them.

[0029] The traction mechanism 4 is used to continuously draw and transport the insulating paper from the roll 2. Its specific structure includes a traction shaft 41, which is rotatably mounted on the frame 1 and connected to the second motor 42 for transmission.

[0030] In the above structure, the insulating paper roll is placed on the roll holder 2 for feeding, and the winding frame is placed on the traction shaft 41 for feeding. After the insulating paper is drawn from the roll, it passes between the support roller 31 and the cutting roller 32 and is fixed on the winding frame for cutting. The insulating paper passing between the support roller 31 and the cutting roller 32 is pressed between them, so that the support roller 31 and the transmission sleeve 35, which is deformed by compression, are pressed against the upper and lower surfaces of the insulating paper respectively. At this time, the blade of the cutter 34 can pass through the slot 351 and penetrate the insulating paper to contact the support roller 31. The first motor 33 and the second motor 42 drive the support roller 31 and the traction shaft 41 to rotate respectively. The traction shaft 41 drives the winding frame to rotate and continuously draws the insulating paper from the roll. The insulating paper passes between the support roller 31 and the cutting roller 32. As the paper passes through continuously, the friction between the transmission sleeve 35 and the insulating paper causes the transmission sleeve 35 and the cutting roller 32 to rotate. The cutting roller 32 drives the cutter 34 to rotate, and the rotating support roller 31 cuts equidistant flanged grooves along the length of the insulating paper on the conveyed insulating paper. The flanged and grooved insulating paper is then continuously wound around the winding frame as the winding frame rotates, thus realizing the winding of the insulating paper. Through the above structure and method, the flanged and grooved operation of the insulating paper can be realized in a streamlined manner, saving labor and improving production efficiency. Furthermore, since the insulating paper is continuously wound around the winding frame, as the outer diameter increases, the flanged grooves of the inner and outer layers of insulating paper are staggered in the radial direction of the winding frame, so that the insulation parts formed by subsequent folding are interlaced and the gaps are eliminated, ensuring the overall insulation performance of the winding frame.

[0031] Furthermore, based on the above structure, two adjusting sliders 36 are vertically slidably mounted on the frame 1, located at both ends of the cutting roller 32. The two ends of the cutting roller 32 are rotatably mounted on the two adjusting sliders 36. Adjusting screws 37 are rotatably mounted on the adjusting sliders 36 and screwed to the frame 1. By rotating the adjusting screws 37, the adjusting sliders 36 can be driven to slide vertically on the frame 1, thereby driving the cutting roller 32 to move vertically and adjust the gap between the transmission sleeve 35 and the support roller 31. This facilitates the cutting operation of the insulating paper and ensures that the gap between the transmission sleeve 35 and the support roller 31 is precisely matched with the thickness of the insulating paper, thereby ensuring that the support roller 31 and the cutter 34 can stably cooperate to perform the edge-flipping and grooving operation on the insulating paper.

[0032] In addition, based on the above structure, a fixed clamping plate 43 is fixedly installed on the traction shaft 41, and a movable clamping plate 44 opposite to the fixed clamping plate 43 is detachably connected to the end of the traction shaft 41. The detachable connection between the movable clamping plate 44 and the traction shaft 41 can be achieved by threaded connection, bolt connection, etc. A support rod 441 for radial limiting by a limiting block 45 is fixedly installed on the movable clamping plate 44. The limiting block 45 is detachably connected to the frame 1. When the winding frame is set on the traction shaft 41, the limiting block 45 is removed. Remove the movable clamping plate 44 from the traction shaft 41, then put the winding skeleton on the traction shaft 41 and press it against the fixed clamping plate 43. Then connect the movable clamping plate 44 to the traction shaft 41 and work with the fixed clamping plate 43 to clamp and fix the winding skeleton. Finally, install the limiting block 45 to radially limit the support rod 441, ensuring the stability of the winding skeleton when it rotates with the traction roller, and ensuring the stability of the traction insulation paper during feeding. This ensures the stability and quality of the insulation paper during winding, and also facilitates the disassembly and assembly of the winding skeleton on the traction mechanism 4 for easy loading and unloading.

[0033] Furthermore, based on the above structure, the cutter 34 has a T-shaped mounting portion 341. The circumferential side of the cutting roller 32 has several mounting grooves 321 that correspond one-to-one with several hollowed-out grooves 351 and match the mounting portion 341. The mounting grooves 321 extend through the cutting roller 32 axially toward the end of the cutting roller 32. The mounting portion 341 passes through the opening of the mounting groove 321 and enters the mounting groove 321. Each end of the cutting roller 32 is detachably connected to a mounting plate 322 that closes the opening of the mounting groove 321 by bolts. The mounting plate 322 is rotatably mounted on the frame 1. The cutter 34 is detachably connected to the cutting roller 32 through the cooperation of the mounting portion 341 and the mounting groove 321, which facilitates the replacement and maintenance of the cutter 34 during equipment use.

[0034] Furthermore, based on the above structure, several guide rods 5 are provided between the material roll frame 2 and the grooving mechanism 3, and between the grooving mechanism 3 and the traction mechanism 4. After the insulating paper on the material roll is drawn out, it passes around several guide rods 5 located between the material roll frame 2 and the grooving mechanism 3 in sequence. The insulating paper passing between the cutting roller 32 and the supporting roller 31 passes around several guide rods 5 located between the grooving mechanism 3 and the traction mechanism 4 in sequence, so that the insulating paper is always taut on the guide rods 5 during the grooving and winding process, thereby ensuring the quality of the grooving, cutting and winding of the insulating paper.

[0035] In addition, based on the above structure, the guide rod 5 is provided with two width limiting blocks 51 that are spaced apart along the axial direction of the guide rod 5. The distance between the two width limiting blocks 51 on the same guide rod 5 matches the width of the insulating paper. When the insulating paper is stretched on the guide rod 5, the insulating paper is limited in the width direction of the insulating paper to prevent the insulating paper from deviating during the conveying process, thereby ensuring the quality of the slotted cutting and winding of the insulating paper.

[0036] Furthermore, based on the above structure, a swing arm 6 is oscillatingly mounted on the frame 1. An angle displacement sensor 61 is mounted at the end of the swing arm 6. An abutment wheel 62 is mounted on the input shaft of the angle displacement sensor 61. A tension spring 63 is mounted on the frame 1 and acts on the swing arm 6. Under the action of the tension spring 63, the abutment wheel 62 swings with the swing arm 6 and abuts against one of the guide rods 5. When the insulating paper is taut on the guide rod 5, the abutment wheel 62 presses tightly against the insulating paper under the action of the tension spring 63. As the insulating paper is conveyed, the friction between the insulating paper and the abutment wheel 62 drives the abutment wheel 62 to rotate. The rotation of the abutment wheel 62 is converted into conveying distance data of the insulating paper by the angle displacement sensor 61, thereby monitoring the length of the insulating paper wound on the winding frame. The controller controls the working state of the first motor 33 and the second motor 42 based on this data to automatically control the length of the insulating paper wound on the winding frame to meet production requirements.

[0037] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0038] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
