Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic material processing and relates to a material mixing device, in particular to a material mixing device for producing ferrite cores with low temperature sensitivity. Background Art

[0002] Ferrite is a new type of non-metallic magnetic material developed in the 1940s. Because its preparation process and appearance are similar to ceramics, it is sometimes called magnetic porcelain. Ferrite generally refers to a composite oxide of an iron group element and one or more other suitable metal elements. It is a semiconductor and is used as a magnetic medium. Magnetite, whose main component is Fe3O4, is the simplest ferrite and one of the earliest non-metallic magnetic materials used by humans. The magnetic phenomena of magnets attracting each other and attracting iron were discovered in my country over 3,000 years ago. By the end of the 11th century, my country had invented the compass and applied it to navigation.

[0003] A search revealed a Chinese patent document that discloses a mixing device for producing magnetic ferrite cores [Application Number: 202121459689.6; Publication Number: CN 215877624 U]. This mixing device for producing magnetic ferrite cores includes a housing, wherein a first cavity, a second cavity, and a third cavity are provided within the housing. A connecting frame is provided within the first cavity, a clamping plate is fixedly connected to the lower surface of the connecting frame, and a stirring grid plate is fixedly connected to the interior of the clamping plate. A first stirring blade is provided within the second cavity, and a connecting plate is fixedly connected to the left and right inner sides of the second cavity. A heating plate is fixedly connected to the side of the connecting plate away from the second cavity. The present invention, by providing a clamping plate and a stirring grid plate, can crush larger pieces of material and make the material mixing more uniform, thereby improving the mixing efficiency of the device. By providing a first stirring blade and a heating plate, the material can be heated evenly and the mixing rate of the material can be accelerated, thereby improving the practicality of the device.

[0004] Although the splints and stirring grid plates disclosed in this patent can crush larger pieces of material and make the material mix more evenly, thereby improving the mixing efficiency of the device, and by providing a first stirring blade and a heating plate, the material can be heated evenly and the mixing rate of the material can be accelerated, thereby improving the practicality of the device, the stirring blade can only rotate horizontally to mix the material, and multiple stirring blades cannot rotate vertically and horizontally at the same time to stir and mix, resulting in uneven mixing. Utility Model Content

[0005] The purpose of this utility model is to address the above-mentioned problems in the existing technology and propose a mixing device for the production of low-temperature-sensitive ferrite cores. The technical problem to be solved by this utility model is: how to achieve the simultaneous use of multiple stirring blades that can rotate vertically and horizontally for stirring and mixing, improve the stirring efficiency, and make the stirring more uniform.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] A mixing device for producing low-temperature-sensitive ferrite cores, comprising a mixing box, a hollow shell rotatably connected inside the mixing box, a rotating shaft fixed to the upper end of the hollow shell, a motor 1 fixed to the upper end of the mixing box, an output shaft end of the motor 1 fixedly connected to the rotating shaft, a plurality of stirring rods 1 fixed on the hollow shell, a plurality of sleeves rotatably connected to the stirring rod 1, two stirring rods 2 fixed to the outer wall of the sleeve, a driving mechanism provided between the sleeve and the hollow shell, a sieve plate slidably connected inside the mixing box, an elastic mechanism provided between the sieve plate and the mixing box, a feed port provided at the upper end of the mixing box, and a discharge pipe fixed to the outer wall of the mixing box.

[0008] The working principle of the utility model is as follows: the ferrite cores are poured into the mixing box from the feed port, filtered and screened through the sieve plate, the first motor is started to drive the rotating shaft to rotate, the rotating shaft drives the hollow shell to rotate, the stirring rod one on the hollow shell rotates horizontally to stir the ferrite cores in the mixing box, and then the sleeve is driven to rotate by the driving mechanism, and the stirring rod two on the sleeve rotates vertically to stir the ferrite cores, thereby improving the stirring efficiency and making the stirring more uniform.

[0009] The driving mechanism includes a second motor fixed in a hollow shell, a rotating column fixed to the output shaft end of the second motor, two turbines fixed on the rotating column, a rotating rod connected to the inner rotation of the stirring rod, a vortex fixed on the rotating rod, the vortex engaged with the turbine, and the rotating rod fixedly connected to the sleeve.

[0011] The moving mechanism comprises a fixing rod fixed on the outer wall of the rotating shaft, and an inclined block is fixed on the lower end of the screen plate.

[0012] With the above structure, the fixed rod is driven to rotate by the rotating shaft. When the fixed rod passes through the inclined block, the inclined block is lifted up, and the inclined block drives the screen plate to move up. When the fixed rod leaves the inclined block, the sieve plate is vibrated by the elastic component, thereby realizing the screening of the ferrite core.

[0013] The elastic component includes an annular groove formed on the inner wall of the mixing box. The sieve plate is located in the annular groove, and the upper and lower sides of the sieve plate are fixedly connected to the annular groove via springs.

[0014] With the above structure, by installing a spring, the sieve plate is vibrated, thereby screening the ferrite core.

[0015] The upper and lower ends of the sieve plate are both fixed with convex rings, and the convex rings are in contact with the inner wall of the mixing box.

[0016] With the above structure, the ring groove is shielded by installing the convex ring, thereby preventing the ferrite core from entering the ring groove and affecting the movement of the spring.

[0017] Compared with the existing technology, the mixing device for producing low temperature sensitivity ferrite cores has the following advantages:

[0018] 1. Pour the ferrite cores into the mixing box from the feed port, filter and screen through the sieve plate, start motor 1, drive the shaft to rotate, and the shaft drives the hollow shell to rotate. The stirring rod 1 on the hollow shell rotates horizontally to stir the ferrite cores in the mixing box. Then, the driving mechanism drives the sleeve to rotate, and the stirring rod 2 on the sleeve rotates vertically to stir the ferrite cores, thereby improving the stirring efficiency and making the stirring more uniform.

[0019] 2. By installing the turbine and worm rod, starting the second motor, driving the shaft to rotate, the worm rod on the rotating column drives the turbine to rotate, the turbine drives the rotating rod to rotate, the rotating rod drives the sleeve to rotate, and the stirring rod on the sleeve rotates vertically to stir the ferrite core, thereby improving the stirring efficiency and making the stirring more uniform.

[0020] 3. The fixed rod is driven to rotate by the rotating shaft. When the fixed rod passes through the tilting block, the tilting block is lifted up, and the tilting block drives the screen plate to move up. When the fixed rod leaves the tilting block, the screen plate is vibrated through the elastic component, thereby realizing the screening of the ferrite core. BRIEF DESCRIPTION OF THE DRAWINGS
