Description

Technical Field

[0001] This utility model relates to the technical field of powder filling devices, and in particular to a powder filling device for integrally molded inductors. Background Technology

[0002] In the process of producing integral molded inductors, magnetic powder needs to be filled, making the use of a powder filling device essential.

[0003] To address this, patent CN114141528A discloses an integrated ultra-thin inductor high-precision powder filling machine, belonging to the field of inductor manufacturing technology. It includes a main body with a motor mounted at its top. The output end of the motor is connected to a first rotating rod, and a first gear disk is fixed to the outer wall of the first rotating rod. A conveyor belt is provided on the outer wall of the first gear disk. In summary, this invention, by configuring a main body, motor, first gear disk, conveyor belt, material box, powder filling box, and push plate, allows the powder filling machine to fill the product through a feeding pipe at the bottom of the powder filling box when the first connecting rod rotates to the highest position of the first rotating disk. This effectively ensures the uniformity of powder filling and allows for simultaneous filling of multiple product groups, making it convenient and fast. Furthermore, the entire device uses only one motor, achieving an efficiency that multiple motors cannot, thus saving costs and improving powder filling efficiency—a win-win situation.

[0004] The powder filling device described above is difficult to adjust the powder filling frequency and prevent clumping when storing magnetic powder, which limits its practical application. Utility Model Content

[0005] The purpose of this invention is to provide a powder filling device for integral molded inductors, which solves the shortcomings of existing powder filling devices for integral molded inductors in preventing clumping and adjusting powder filling efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a powder filling device for integrally molded inductors, including a main body and a material storage base;

[0007] The top of the main body is provided with a storage seat, the top of the storage seat is provided with a feed port, and the top of the storage seat is provided with an anti-caking structure.

[0008] The anti-caking structure includes a stirring motor installed on the top of the storage seat and a heating chamber opened inside the storage seat. The bottom end of the stirring motor is provided with an output shaft, and a stirring impeller is installed on the outer wall of the output shaft. The heating chamber is provided with a heating seat, and heating wires are evenly arranged inside the heating seat.

[0009] The top of the main body is provided with a powder-filling structure.

[0010] Preferably, the output shaft extends into the interior of the storage seat, and the stirring impellers are evenly distributed on the outer wall of the output shaft.

[0011] Preferably, the heating wires are evenly distributed inside the heating base.

[0012] Preferably, the powder filling structure includes a movable groove at the top of the main body and a discharge port at the bottom of the storage seat. Guide rods are uniformly fixed inside the movable groove. An adjusting motor is installed on the outer wall of the main body on one side of the movable groove. A two-way lead screw is provided on one side of the adjusting motor. A metering motor is installed on one side of the discharge port. A metering shaft is provided on one side of the metering motor. Metering plates are uniformly installed on the outer wall of the metering shaft.

[0013] Preferably, the guide rods are symmetrically distributed inside the moving groove, and each guide rod passes through one side of the storage seat.

[0014] Preferably, the bidirectional lead screw passes through one side of the storage seat, and the bidirectional lead screw is threadedly connected to the storage seat.

[0015] Preferably, the metering shaft extends into the interior of the discharge port, and the metering plates are evenly distributed on the outer wall of the metering shaft.

[0016] The advantages of the powder filling device for integrally molded inductors provided by this utility model are as follows:

[0017] By incorporating an anti-caking structure, the stirring motor is activated, causing the output shaft to rotate inside the storage base. This allows the stirring impeller to stir the magnetic powder inside the storage base, preventing clumping. Furthermore, a heating seat is installed on the inner wall of the storage base, and the magnetic powder inside is heated and dried using its internal heating wires, further enhancing the anti-caking performance. This achieves the goal of preventing the magnetic powder from clumping during storage, making it unsuitable for filling.

[0018] By setting up a powder filling structure, starting the metering motor causes the metering shaft extending into the discharge port to rotate. Metering plates are evenly installed on the outer wall of the metering shaft, and one side of the metering plate abuts against the inner wall of the discharge port. By adjusting the rotation speed of the metering shaft, the efficiency of magnetic powder being discharged from the discharge port can be adjusted, thereby achieving the purpose of convenient metering powder filling.

[0026] Please see Figures 1-5 The powder filling device for integrally molded inductors provided by this utility model includes a main body 1 and a material storage base 2.

[0027] Reference Figures 1-4 As shown, a storage base 2 is provided on the top of the main body 1. A feed inlet 3 is provided on the top of the storage base 2. An anti-caking structure 4 is installed on the top of the storage base 2. The anti-caking structure 4 includes a stirring motor 401 installed on the top of the storage base 2 and a heating chamber 402 opened inside the storage base 2. An output shaft 403 is provided at the bottom of the stirring motor 401. A stirring impeller 404 is installed on the outer wall of the output shaft 403. A heating seat 405 is provided inside the heating chamber 402. Heating wires 406 are evenly arranged inside the heating seat 405. The output shaft 403 extends into the interior of the storage base 2. The stirring impellers 404 are evenly distributed on the outer wall of the output shaft 403. The heating wires 406 are evenly distributed inside the heating seat 405.

[0028] To facilitate the production of integrally molded inductors, powder filling is required, necessitating the storage of magnetic powder. However, during storage, moisture and other factors can cause clumping, making it difficult to drain and fill the powder. Therefore, an anti-caking structure 4 is incorporated. A heating chamber 402 is formed in the inner wall of the main body 1, containing a heating seat 405 and a heating wire 406. The heating wire 406 heats the interior of the main body 1, preventing the magnetic powder from clumping. Furthermore, a stirring motor 401 is activated, causing the output shaft 403 to rotate within the main body 1. An impeller 404 is mounted on the outer wall of the output shaft 403 to further stir the magnetic powder, preventing adhesion and clumping. This significantly increases the practicality of the device.

[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a powder filling structure 5 is provided on the top of the main body 1. The powder filling structure 5 includes a moving groove 501 on the top of the main body 1 and a discharge port 502 at the bottom of the storage seat 2. Guide rods 503 are uniformly fixed inside the moving groove 501. An adjusting motor 504 is installed on the outer wall of the main body 1 on one side of the moving groove 501.

A metering shaft 507 is provided on one side of the metering motor 506. Metering plates 508 are uniformly installed on the outer wall of the metering shaft 507. The guide rods 503 are symmetrically distributed inside the moving groove 501. All guide rods 503 pass through one side of the storage seat 2. The bidirectional lead screw 505 passes through one side of the storage seat 2 and is threadedly connected to the storage seat 2. The metering shaft 507 extends into the discharge port 502. The metering plates 508 are evenly distributed on the outer wall of the metering shaft 507.

[0030] To facilitate the filling of magnetic powder, a filling structure 5 is provided. The storage seat 2 is slidably connected inside the moving groove 501, and the guide rod 503 passes through both sides of the storage seat 2 to guide it. The regulating motor 504 is started to make the bidirectional lead screw 505 rotate inside the moving groove 501 and is threadedly connected to the storage seat 2, thereby moving the storage seat 2 in the moving groove 501 to the position where powder needs to be filled. In order to adjust the discharge rate, the metering motor 506 is started to make the metering shaft 507 rotate inside the discharge port 502. The metering plate 508 fixed on its outer wall abuts against the inner wall of the discharge port 502 on the side away from the metering shaft 507.
