Description

Technical Field

[0001] This utility model relates to the field of amorphous and nanocrystalline magnetic core technology, and in particular to an amorphous and nanocrystalline magnetic core winding machine. Background Technology

[0002] Amorphous nanocrystals have advantages such as low core loss, high resistivity, good frequency characteristics, high magnetic induction intensity, and strong corrosion resistance. Magnetic cores made by winding amorphous nanocrystal strips are widely used in filters, transformers, and instrument transformers.

[0003] Currently, when winding amorphous and nanocrystalline magnetic cores, the amorphous and nanocrystalline strip is directly attached to a fixed post, one end of the strip is connected to a winding mold, and then the winding mold is rotated by a motor to wind the strip onto the mold. During the winding process, the strip roll is passively rotated to release the strip. When the winding finally stops, the strip is prone to continue to be released due to inertia, which causes the strip already wound on the mold to loosen and affects the tightness of the winding. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an amorphous nanocrystalline magnetic core winding machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An amorphous nanocrystalline magnetic core winding machine includes a base, a fixing column fixedly installed at the top of one end of the base, a placement platform installed at the top of the other end of the base, a winding mold placed on the placement platform, two fixing frames fixedly installed in the middle of the top surface of the base, a clamping strap installed inside the fixing frame, and a driving mechanism installed at the bottom of the base, the driving mechanism connecting the clamping strap and the placement platform.

[0007] Preferably, the placement platform includes a rotating wheel that movably fits against the top of the base. The top of the rotating wheel has a groove, and a double-ended stud is rotatably sleeved in the groove. Two clamping blocks are slidably engaged in the groove, and the clamping blocks are threadedly sleeved on both ends of the double-ended stud. The clamping blocks are movably engaged in the inner cavity of the winding mold.

[0008] Preferably, the side of the clamping block that is far apart has an arc-shaped structure, one end of the double-ended stud penetrates the side wall of the rotating wheel and is fixedly installed with a knob, and rubber damping rings are fixedly installed on the inner walls of both ends of the slide groove, and the rubber damping rings are sleeved on the double-ended stud.

[0009] Preferably, the driving mechanism includes a drive shaft, with the drive shaft rotatably passing through both ends of the fixed frame and the base. A drive roller is fixedly sleeved on the top of the drive shaft, and the clamping belt is sleeved between the drive rollers. A fixed seat is fixedly installed on the bottom of the base, and a motor is fixedly installed on the fixed seat. The output shaft of the motor is fixedly connected to a rotating wheel. The output shaft of the motor is connected to a drive shaft via a drive wheel and a drive belt. Drive gears are fixedly sleeved on the bottom of the drive shafts at one end of both fixed frames, and the drive gears mesh with each other.

[0010] Preferably, a fixing plate is fixedly installed on the top of the base between the fixing frame and the rotating wheel. Two guide rods are slidably sleeved on the fixing plate. A U-shaped seat is fixedly installed between one end of the guide rods. A pressure wheel is rotatably installed between the U-shaped seats. A spring is sleeved on the guide rod between the U-shaped seat and the fixing plate.

[0011] Preferably, the spring is always in a compressed state, and a limit ring is fixedly installed at the end of the guide rod away from the U-shaped seat.

[0012] The amorphous and nanocrystalline magnetic core winding machine proposed in this utility model has the following advantages:

[0013] 1. Amorphous and nanocrystalline strips are wound onto fixed posts, and winding dies are fitted onto placement platforms. The movable end of the strip passes through two clamping belts and pressure rollers and is connected to the winding die. A motor drives the rotating wheel to rotate, which facilitates the winding of the strip. The drive shaft is driven to rotate synchronously through the drive wheel and drive belt. The drive shafts rotate synchronously through the drive gears. In this way, the clamping belts and the rotating wheel start and stop synchronously, realizing the active feeding and tensioning of the strip. When winding stops, the rotating wheel and the clamping belt stop synchronously to avoid the inertial release of amorphous and nanocrystalline materials and ensure the tightness of the winding.

[0014] 2. When the number of winding turns increases, the length of the strip wound by the winding die will be greater than the strip released by the clamping belt in the same time period. At this time, the strip will pull the U-shaped seat to move, and the spring will be compressed. Thus, the winding of the strip is ensured by the movement of the clamping wheel.

Spring Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0021] Reference Figure 1 and Figure 2 This application provides an amorphous nanocrystalline magnetic core winding machine, including a base 1. A fixed post 2 is fixedly installed on the top of one end of the base 1, and a placement platform 3 is installed on the top of the other end of the base 1. A winding mold 4 is placed on the placement platform 3. Two fixed frames 5 are fixedly installed in the middle of the top surface of the base 1. Clamping straps 6 are installed inside the fixed frames 5. A drive mechanism 7 is installed at the bottom of the base 1. The drive mechanism 7 connects the clamping straps 6 and the placement platform 3. The amorphous nanocrystalline strip is wound on the fixed post 2, and the winding mold 4 is sleeved on the placement platform 3. The movable end of the strip is passed between the two clamping straps 6 and connected to the winding mold 4. The drive mechanism 7 simultaneously drives the placement platform 3 and the clamping straps 6 to rotate. The clamping straps 6 clamp the strip and release it, and the strip is wound by the winding mold 4. The strip can only be released through the conveying of the clamping straps 6. After the winding is completed, the clamping straps 6 stop synchronously to ensure that the strip between the clamping straps 6 and the winding mold 4 is always taut, thereby ensuring tight winding.

[0022] Reference Figure 1 and Figure 2The placement platform 3 includes a rotating wheel 31, which movably fits the top of the base 1. The top of the rotating wheel 31 has a groove 32, in which a double-ended stud 33 is rotatably fitted. Two clamping blocks 34 are slidably engaged in the groove 32. The clamping blocks 34 are threaded onto both ends of the double-ended stud 33 and are movably engaged into the inner cavity of the winding mold 4. The opposite sides of the clamping blocks 34 have an arc-shaped structure. One end of the double-ended stud 33 passes through the side wall of the rotating wheel 31 and is fixedly fitted with a knob. Rubber damping rings are fixedly installed on the inner walls of both ends of the groove 32, and the rubber damping rings are fitted onto the double-ended stud 33. The double-ended stud 33 causes the two clamping blocks 34 to move closer or further away simultaneously. When the clamping blocks 34 are close together, the winding mold 4 can be fitted onto the outside of the two clamping blocks 34 or removed after winding. When the clamping blocks 34 are far apart, they press against the inner wall of the winding mold 4, thereby clamping the mold.

[0023] Reference Figure 1 and Figure 2 The drive mechanism 7 includes a drive shaft 71. The drive shaft 71 is rotatably inserted through both ends of the fixed frame 5 and the base 1. The top of the drive shaft 71 is fixedly sleeved with a drive roller 72. The clamping belt 6 is sleeved between the drive rollers 72. The bottom of the base 1 is fixedly installed with a fixed seat 73. The fixed seat 73 is fixedly installed with a motor 74. The output shaft of the motor 74 is fixedly connected to the rotating wheel 31. The output shaft of the motor 74 is connected to one of the drive shafts 71 through a drive wheel and a drive belt. The bottom of the drive shafts 71 at one end of the two fixed frames 5 is fixedly sleeved with a drive gear 75, and the drive gears 75 mesh with each other. The motor 74 drives the rotating wheel 31 to rotate, which facilitates the winding of the strip. The drive shaft 71 is driven to rotate synchronously through the drive wheel and the drive belt. The drive shafts 71 rotate synchronously through the drive gears 75. In this way, the clamping belt 6 starts and stops synchronously with the rotating wheel 31, realizing the active feeding and tensioning of the strip, ensuring the tightness of the amorphous nanocrystalline magnetic core.

[0024] Reference Figure 1 and Figure 3 A fixed plate 8 is fixedly installed on the top of the base 1 between the fixed frame 5 and the rotating wheel 31. Two guide rods 9 are slidably sleeved on the fixed plate 8. A U-shaped seat 10 is fixedly installed between one end of the guide rods 9. A pressure wheel 11 is rotatably installed between the U-shaped seats 10. A spring 12 is sleeved on the guide rod 9 between the U-shaped seat 10 and the fixed plate 8. The spring 12 is always in a compressed state. A limit ring is fixedly installed on the end of the guide rod 9 away from the U-shaped seat 10. As the number of turns of the strip on the mold increases, the rotating wheel... 31. The length of the winding increases with each rotation. Therefore, during the initial installation, the spring 12 is kept in the most relaxed state, that is, the U-shaped seat 10 is furthest from the fixed plate 8. After the strip is released from the clamping belt 6, it passes through the pressure roller 11 and is then connected to the mold. When the number of winding turns increases, the length of the strip wound by the winding mold 4 will be greater than the strip released by the clamping belt 6 in the same time period. At this time, the strip will pull the U-shaped seat 10 to move, and the spring 12 will be compressed. Thus, the movement of the pressure roller 11 ensures the winding and tightness of the strip.

[0025] Working principle: Amorphous and nanocrystalline strips are wound onto fixed posts 2, and winding molds 4 are fitted onto placement platforms 3. The movable end of the strip passes through two clamping belts 6 and pressure rollers 11 and is connected to the winding mold 4. Motor 74 drives the rotating wheel 31 to rotate, which facilitates the winding of the strip. The drive shaft 71 is driven to rotate synchronously through the drive wheel and drive belt. The drive shafts 71 rotate synchronously through the drive gears 75. Thus, the clamping belts 6 and the rotating wheel 31 start and stop synchronously, realizing the active feeding and tensioning of the strip. When the number of winding turns increases, the length of the strip wound by the winding mold 4 will be greater than the strip fed out by the clamping belts 6 in the same time period. At this time, the strip will pull the U-shaped seat 10 to move, and the spring 12 will be compressed. Thus, the movement of the pressure rollers 11 ensures the winding of the strip. When the winding stops, the rotating wheel 31 and the clamping belts 6 stop synchronously to avoid the inertial release of the amorphous and nanocrystalline material and ensure the tightness of the winding.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
