Description

Technical Field

[0001] This utility model relates to the field of microcrystalline iron core production technology, specifically a winding machine for microcrystalline iron core production. Background Technology

[0002] Microcrystalline iron cores are a high-performance soft magnetic material with high permeability, low loss, and excellent temperature stability. They are widely used in power electronics, new energy, communications, and other fields. The typical composition is Fe-Si-B-Nb-Cu, with an iron content of about 70% to 80%. Small amounts of Nb and Cu are added to improve the nanocrystal formation ability. High-purity raw materials are smelted under vacuum or inert gas protection to ensure uniform composition and no impurities. The molten alloy is sprayed onto a high-speed rotating copper roller with a cooling rate of 10^6 K / s to form an amorphous thin strip. The roller speed, melt temperature, and distance between the nozzle and the roller surface affect the thickness and uniformity of the strip. The winding machine used for microcrystalline iron core production is a key piece of equipment specifically designed for manufacturing nanocrystalline alloy iron cores. Its core function is to precisely wind ultra-thin strips into ring, rectangular, or special-shaped iron cores.

[0003] The existing authorized publication number CN215069623U discloses a winding machine for producing microcrystalline iron cores, which includes a winding machine body, an adjustment device fixedly connected inside the winding machine body, and a winding roller rotatably connected inside the winding machine body. This utility model facilitates the adjustment of the rotation speed of the winding roller, thereby enabling the winding roller to produce the most microcrystalline iron cores in the shortest time during the production and processing of microcrystalline iron cores, thus maximizing its efficiency. In some cases, the winding machine for producing microcrystalline iron cores uses the adjustment of the height of the slider in the groove, driven by the screw thread or tightened by the adjustment bolt, to adjust the position of the adjustment roller on the slider to achieve pressure adjustment.

[0004] Existing winding machines for microcrystalline iron core production have the following problems: the former may cause the microcrystalline iron core strip to be too tight or too loose during the winding process, making it impossible to effectively and stably adjust the tension; the latter has poor stability in adjusting the rollers, which in turn affects the quality of the microcrystalline iron core strip winding. Therefore, we propose a winding machine for microcrystalline iron core production. Utility Model Content

When winding microcrystalline iron cores, the machine can accurately and stably adjust the strip tension, which has good stability and ensures that the material maintains constant tension during winding. This avoids the impact of tension fluctuations on the quality of the microcrystalline iron core strip winding and can effectively solve the problems in the background art.

The front end of the slide plate is rotatably connected to the support rod, and the lower pressure roller is fixedly sleeved on the outside of the support rod. Symmetrical guide rods are fixedly connected to the rear side between the upper and lower inner walls of the machine box. A support block is slidably connected between the two guide rods. The front end of the support block is fixedly connected to the rear end of the slide plate. When winding the microcrystalline iron core, the tension of the strip is precisely and stably adjusted, which has good stability and ensures that the material maintains a constant tension during winding, avoiding the impact of tension fluctuations on the quality of the microcrystalline iron core strip winding.

[0008] Furthermore, a microcontroller is provided on the rear side of the left end of the chassis. The input terminal of the microcontroller is electrically connected to an external power source to provide electrical connections for various electrical appliances.

[0009] Furthermore, the tension adjustment mechanism also includes a drive assembly, which includes a connecting rod, a U-shaped block, a slider, and an adjustment platform. The adjustment platform is provided on the rear side of the bottom wall of the chassis. The adjustment platform is slidably connected to the left and right sides of the slider. The front end of the slider is fixedly connected to the U-shaped block. The upper end of the U-shaped block is rotatably connected to the left and right sides of the rear end of the support block through a pin, providing a rotatable connection.

[0010] Furthermore, the drive assembly also includes a bidirectional lead screw and a bellows. The bidirectional lead screw is rotatably connected between the left and right inner walls of the adjustment platform. The threaded hole in the middle of the slider is threadedly connected to the left and right ends of the bidirectional lead screw. Bellows are fixedly connected between the left and right inner walls of the adjustment platform and the opposite outer sides of the horizontally adjacent sliders, as well as between the inner sides of the two sliders. The bellows are all sleeved on the outside of the bidirectional lead screw to improve the movable connection.

[0011] Furthermore, the drive assembly also includes a motor, which is located at the left end of the adjustment platform. The right end of the output shaft of the motor is fixedly connected to the left end of the bidirectional lead screw, and the input end of the motor is electrically connected to the output end of the microcontroller to provide adjustment drive.

[0012] Furthermore, a threaded rod is fixedly connected to the front end of the take-up roller, and a fixing nut is connected to the external thread of the threaded rod to facilitate the fixing of the take-up roller.

[0013] Furthermore, a tension sensor is provided on the left side of the front end of the partition, and the tension sensor is bidirectionally electrically connected to the microcontroller to provide tension monitoring.

[0014] Furthermore, a second motor is provided on the right side of the rear end of the partition. The front end of the output shaft of the second motor is fixedly connected to the rear end of the winding roller. A third motor is provided on the right side of the rear end of the partition.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This winding machine for producing microcrystalline iron cores has the following advantages:

[0016] Driven by motor one, the support block slides downward between two guide rods via a bidirectional lead screw, slider, U-shaped block, and connecting rod. This causes the slide plate to move the lower pressure roller downward, applying pressure to the strip and achieving dynamic tension adjustment. The support block, connecting rod, and U-shaped block form an isosceles trapezoidal structure. The self-locking and stable bidirectional lead screw drives the two connecting rods to change their tilt angles simultaneously and with the same amplitude, achieving stable and powerful position adjustment of the support block. Finally, the lower pressure roller moves smoothly downward, applying stable pressure to the strip and ensuring that the microcrystalline strip is wound with appropriate tension. During the winding of the microcrystalline iron core, the precise and stable adjustment of the strip tension provides good stability, ensuring that the material maintains constant tension during winding and avoiding the impact of tension fluctuations on the quality of the microcrystalline iron core strip winding.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-7This embodiment provides a technical solution: a winding machine for producing microcrystalline iron cores, including a chassis 1, with a partition 14 inside the chassis 1. A door is hinged to the front end of the chassis 1. A pair of symmetrical guide rollers 3 are rotatably connected to the feed inlet on the upper left side of the chassis 1. A traction roller 4 is rotatably connected to the left side of the front end of the partition 14 via a rotating column. A pair of symmetrical guide rollers 5 are rotatably connected to the middle of the front end of the partition 14 via a rotating shaft. A winding roller 6 is rotatably connected to the right side of the front end of the partition 14. A winding drum 7 is movably sleeved on the outside of the winding roller 6. The machine also includes a tension adjustment mechanism 8. The rear side of the left end of the chassis 1... A microcontroller 2 is provided, with its input terminal electrically connected to an external power source. A threaded rod 9 is fixedly connected to the front end of the take-up roller 6, and a fixing nut 10 is connected to the external thread of the threaded rod 9. A tension sensor 11 is located on the left side of the front end of the partition 14, to the left of the traction roller 4. The tension sensor 11 is bidirectionally electrically connected to the microcontroller 2. A second motor 12 is located on the right side of the rear end of the partition 14, with its output shaft fixedly connected to the rear end of the take-up roller 6. A third motor 13 is located on the right side of the rear end of the partition 14, with its output shaft fixedly connected to the rear end of the rotating column. The input terminals of motor 13 and motor 3 are electrically connected to the output terminals of microcontroller 2. When the winding machine for producing microcrystalline iron cores is working, the drive box door is first opened, then the take-up drum 7 is placed over the take-up roller 6, and the fixing nut 10 is rotated. The fixing nut 10 fixes the take-up drum 7 through the threaded rod 9. Then the door is closed. The microcrystalline strip is introduced between the two guide rollers 1 3 at the feed port on the left side of the machine box 1, passes the upper end of the tension sensor 11, then the lower end of the traction roller 4, then the upper end of the left guide roller 2 5, then around the lower end of the pressure roller 81, and then the upper end of the right guide roller 2 5, and wound onto the take-up drum 7. Tension sensor 11 monitors the strip tension in real time and transmits the data to microcontroller 2. Microcontroller 2 integrates the information and controls motors 12 and 13. The output shaft of motor 12 drives the take-up roller 6 to rotate, which in turn drives the take-up drum 7 to rotate and wind the microcrystalline strip. The output shaft of motor 13 drives the rotating column to rotate, which in turn drives the traction roller 4 to rotate and traction the microcrystalline strip. After winding is completed, the box door is opened, and then the fixing nut 10 is rotated counterclockwise to remove the fixing nut 10. The take-up drum 7 is then removed and the box door is closed.

[0027] Tension adjustment mechanism 8: It includes a lower pressure roller 81, a support rod 82, a slide plate 83, a support block 84, and a guide rod 85. A groove is opened in the center of the partition plate 14. The slide plate 83 is slidably connected inside the groove. The front end of the slide plate 83 is rotatably connected to the support rod 82. The lower pressure roller 81 is fixedly sleeved on the outside of the support rod 82. The lower pressure roller 81 is located between two guide rollers 85. The left and right symmetrical guide rods 85 are fixedly connected to the rear side between the upper and lower inner walls of the housing 1. The support block 84 is slidably connected between the two guide rods 85. The front end of the support block 84 is fixedly connected to the rear end of the slide plate 83. Tension adjustment mechanism 8 also includes a drive assembly 8. 6. The drive assembly 86 includes a connecting rod 861, a U-shaped block 862, a slider 863, and an adjusting platform 867. The adjusting platform 867 is located on the rear side of the bottom wall of the chassis 1. The adjusting platform 867 has symmetrical sliders 863 slidably connected inside. The front ends of the sliders 863 are fixedly connected to the U-shaped blocks 862. The upper ends of the U-shaped blocks 862 are rotatably connected to the left and right sides of the rear end of the support block 84 via pins. The drive assembly 86 also includes a bidirectional lead screw 864 and a bellows 865. The bidirectional lead screw 864 is rotatably connected between the left and right inner walls of the adjusting platform 867. The threaded hole in the middle of the slider 863 is connected to the bidirectional lead screw 861. The left and right ends of the rod 864 are threaded together. Bellows 865 are fixedly connected between the left and right inner walls of the adjusting platform 867 and the opposite outer sides of the horizontally adjacent sliders 863, as well as between the inner sides of the two sliders 863. The bellows 865 are all sleeved on the outside of the bidirectional lead screw 864 (the bellows 865 prevent dust from entering the adjusting platform 867, ensuring the accuracy of the lead screw transmission). The drive assembly 86 also includes a motor 866. A motor 866 is located at the left end of the adjusting platform 867. The right end of the output shaft of the motor 866 is fixedly connected to the left end of the bidirectional lead screw 864. The input end of the motor 866 is electrically connected to the output end of the microcontroller 2. When… When tension deviation occurs, the microcontroller 2 controls the operation of motor 866. The output shaft of motor 866 drives the bidirectional lead screw 864 to rotate. The bidirectional lead screw 864 drives the slider 863 in the adjusting table 867 to slide towards each other. The slider 863 drives the support block 84 to slide downward between the two guide rods 85 through the U-shaped block 862 and the connecting rod 861. This causes the slide plate 83 to move in the groove of the partition plate 14, thereby adjusting the pressure of the downward movement of the pressure roller 81 on the strip and realizing dynamic tension adjustment. The pressure roller 81 is located between the two guide rollers 5, which can accurately control the strip tension and ensure that the microcrystalline strip is wound with appropriate tension.

[0028] The working principle of the winding machine for producing microcrystalline iron cores provided by this utility model is as follows: When the winding machine for producing microcrystalline iron cores is working, first, the drive box door is opened, then the winding drum 7 is placed outside the winding roller 6, and the fixing nut 10 is rotated. The fixing nut 10 fixes the winding drum 7 through the threaded rod 9. Then, the door is closed. The microcrystalline strip is introduced between the two guide rollers 1 3 at the feed port on the left end of the machine box 1, passes the upper end of the tension sensor 11, then the lower end of the traction roller 4, then the upper end of the left guide roller 2 5, then around the lower end of the pressure roller 81, and then the upper end of the right guide roller 2 5, and wound onto the winding drum 7. The tension sensor 11 monitors the strip tension in real time and transmits the data to the microcontroller 2. The microcontroller 2 integrates the information and controls the operation of motors 12 and 13. The output shaft of motor 12 drives the winding roller 6 to rotate, and the winding roller 6 drives the winding drum 7 to rotate to wind the microcrystalline strip. The output shaft of motor 13 drives the winding roller 6 to rotate. The output shaft drives the rotating column to rotate, which in turn drives the traction roller 4 to rotate and pull the microcrystalline strip. When the tension deviates, the microcontroller 2 controls the operation of the motor 866. The output shaft of the motor 866 drives the bidirectional lead screw 864 to rotate. The bidirectional lead screw 864 drives the slider 863 in the adjusting table 867 to slide towards each other. The slider 863 drives the support block 84 to slide downward between the two guide rods 85 through the U-shaped block 862 and the connecting rod 861. This causes the slide plate 83 to move in the groove of the partition 14. Through the two sliding guides, the downward movement of the pressure roller 81 is adjusted to provide stable pressure on the strip, thereby achieving dynamic tension adjustment. The pressure roller 81 is located between the two guide rollers 5, which can accurately control the strip tension and ensure that the microcrystalline strip is wound with appropriate tension. After winding, the box door is opened, and then the fixing nut 10 is rotated counterclockwise to remove the fixing nut 10. The take-up drum 7 is then removed and the box door is closed.

[0029] It is worth noting that in the above embodiments, the motor 866, tension sensor 11, motor 12, and motor 13 can all be selected from 35BYJ46, and the tension sensor 11 can be a MEASSensors Model 22 tension sensor. The microcontroller 2 controls the operation of the motor 866, tension sensor 11, motor 12, and motor 13 using methods commonly used in the prior art.
