Description

Technical Field

[0001] The present application belongs to the technical field of mixing equipment, and in particular relates to a mixer for magnet processing. Background Art

[0002] The magnetic powder core material on the market now is a composite soft magnetic material made by mixing and pressing ferromagnetic powder and insulating medium. Magnetic powder includes Fe, Fe-Ni-Mo.Fe-Si-Al metal powder and amorphous and nanocrystalline alloy powder. The insulating coating agent can be roughly divided into organic coating agent and inorganic coating agent. The pressing methods mainly include cold pressing, warm pressing, vacuum hot pressing, two-step pressing, mold wall lubrication pressing, etc. At present, the magnetic powder core mixing equipment on the market is generally such as a cone machine or a stirring device is set inside. The powder of the alloy magnetic powder core is stirred and sheared through the rotation of the stirring device. Due to the static setting of the stirring barrel, there must be a mixing dead corner inside the stirring barrel, which has a poor mixing effect on the powder of the alloy magnetic powder core with trace elements added, and the mixing uniformity is not high and the mixing efficiency is low.

[0003] The existing foreign patent with publication number KR102611039B1 discloses a heating powder mixer. The heating powder mixer according to an embodiment of the present invention comprises: a container part, which comprises a container for containing powder; a mixing unit arranged in the container to mix the powder; and a driving unit for rotating the mixing unit.

[0004] Although the above mixer can achieve powder mixing, the efficiency of the mixer is low and the uniformity of the mixed materials cannot be guaranteed. Improvements are made to this. Summary of the invention

[0005] The purpose of the present application is to provide a mixer for magnet processing in order to solve the above-mentioned technical problems, which can improve the mixing efficiency of magnetic powder and ensure the uniform effect after mixing.

[0006] The present application provides a mixer for magnet processing, comprising:

[0007] Base;

[0008] A driving mechanism is mounted on the base;

[0009] An outer cylinder is placed on the base, and the outer cylinder is provided with an inner cavity;

[0010] A stirring mechanism is installed on the outer cylinder, and the stirring mechanism is provided with stirring blades;

[0011] Among them, the axis of the inner cavity intersects with the axis of the outer cylinder, an outer cover body is provided on one side of the outer cylinder, the outer cylinder is provided with an inner cover body corresponding to the inner cavity, the inner cover body is placed on the same side of the outer cylinder as the outer cover body, and an abutment mechanism is provided between the outer cover body and the inner cover body.

[0012] The driving device is used to drive the outer cylinder to rotate. When the outer cylinder rotates, the magnetic powder is placed in the inner cavity to flow, and because the axis of the inner cavity intersects with the axis of the outer cylinder, the magnetic powder is placed between the two ends of the inner cavity and flows back and forth. At the same time, the stirring mechanism is used to increase the stirring effect on the magnetic powder in the inner cavity and accelerate the stirring. The axis of the inner cavity intersects with the axis of the outer cylinder to increase the fluidity of the powder in the inner cavity, so that the powder at the bottom can also be guaranteed to be evenly mixed. The inner cover body and the outer cover body facilitate the entry and exit of the powder in the inner cavity. When the powder needs to be placed in the inner cavity, the open end of the inner cavity is controlled to face upward. When the powder needs to be discharged from the inner cavity, the open end of the inner cavity is controlled to face downward. It is placed between the outer cover body and the inner cover body through the abutment mechanism to ensure the installation stability of the inner cover body and prevent leakage when the powder is mixed.

[0013] Furthermore, the outer cylinder is provided with a mounting shaft, and the mounting shaft is connected to the driving mechanism.

[0014] The mounting shaft is arranged on an end of the outer cylinder body opposite to the outer cover body, and the entire outer cylinder body is movably mounted on the base through a bracket.

[0015] Further, the stirring shaft is identical to the axis of the inner cavity;

[0016] An inner gear ring is mounted on the base and is aligned with the axis of the mounting shaft;

[0017] Gear, corresponding to the inner gear ring;

[0018] A bracket, installed between the gear and the mounting shaft;

[0019] Universal coupling, connected between the gear and the stirring shaft.

[0020] When the mounting shaft rotates, the gear rotates around the axis of the outer cylinder at the same time as the mounting shaft through the bracket, and meshes with the inner gear ring through the gear. At the same time, the gear rotates around its own axis. The relative position between the gear and the stirring shaft remains unchanged through the bracket. When the gear rotates through the universal coupling, it drives the stirring shaft to rotate.

[0021] Furthermore, the stirring blade is V-shaped, and the stirring blade is provided with a V-shaped inclined surface.

[0022] The stirring blade is installed on the stirring shaft. The stirring blade is V-shaped and can stir the powder flowing back and forth between the two ends in the inner cavity, and the powder is dispersed by the inclined surface to improve the stirring efficiency. The inclined surfaces on both sides of one end of the V-shaped structure of the stirring blade can stir the powder flowing in a circle relative to the inner cavity, further improving the stirring efficiency.

[0023] Furthermore, two ends of the inner cavity are in arc shape.

[0024] The two sides of the inner cavity are in an arc shape, and by eliminating the inner corner in the inner cavity, the powder is not easy to adhere to the inner corner, thereby ensuring that the powder can be mixed more evenly.

[0025] Furthermore, the abutment mechanism includes:

[0026] An abutment seat, movably mounted on the outer cover body;

[0027] The first spring is placed between the abutting seat and the outer cover body.

[0028] The abutment mechanism is movably mounted on an abutment seat on the outer cover body. When the outer cover body is matched with the outer cylinder body, the abutment seat abuts against the inner cover body. The first spring acts on the abutment seat to ensure a more stable connection between the inner cover body and the inner cavity.

[0029] The beneficial effects of this application are:

[0030] 1. When the outer cylinder rotates, the magnetic powder is placed in the inner cavity and flows. Since the axis of the inner cavity intersects with the axis of the outer cylinder, the magnetic powder flows back and forth between the two ends of the inner cavity.

[0031] 2. The stirring mechanism is used to increase the stirring effect on the magnetic powder in the inner cavity, speed up the stirring, and increase the fluidity of the powder in the inner cavity by intersecting the axis of the inner cavity with the axis of the outer cylinder.

[0032] 3. The abutment mechanism is placed between the outer cover and the inner cover to ensure the installation stability of the inner cover and prevent leakage of powder during mixing. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Base 100;

[0043] The driving mechanism 200 is mounted on the base 100;

[0044] The outer cylinder 300 is placed on the base 100, and the outer cylinder 300 is provided with an inner cavity 310;

[0045] A stirring mechanism 400 is installed on the outer cylinder 300, and the stirring mechanism 400 is provided with stirring blades 410;

[0046] Among them, the axis of the inner cavity 310 intersects with the axis of the outer cylinder 300, and an outer cover body 320 is provided on one side of the outer cylinder 300. The outer cylinder 300 is provided with an inner cover body 330 corresponding to the inner cavity 310, and the inner cover body 330 is placed on the same side of the outer cylinder 300 as the outer cover body 320, and an abutment mechanism 340 is provided between the outer cover body 320 and the inner cover body 330.

[0047] The driving device is used to drive the outer cylinder 300 to rotate. When the outer cylinder 300 rotates, the magnetic powder is placed in the inner cavity 310 and flows. Since the axis of the inner cavity 310 intersects with the axis of the outer cylinder 300, the magnetic powder is placed between the two ends of the inner cavity 310 and flows back and forth. At the same time, the stirring mechanism 400 increases the stirring effect on the magnetic powder in the inner cavity 310, speeds up the stirring, and increases the fluidity of the powder in the inner cavity 310 by the axis of the inner cavity 310 intersecting with the axis of the outer cylinder 300. , so that the powder at the bottom can also be guaranteed to be evenly mixed, and the inner cover body 330 and the outer cover body 320 are used to facilitate the powder in and out of the inner cavity 310. When the powder needs to be placed in the inner cavity 310, the open end of the inner cavity 310 is controlled to face upward, and when the powder needs to be discharged from the inner cavity 310, the open end of the inner cavity 310 is controlled to face downward. The abutment mechanism 340 is placed between the outer cover body 320 and the inner cover body 330 to ensure the installation stability of the inner cover body 330 and prevent the powder from leaking out during mixing.

[0048] Furthermore, the outer cylinder 300 is provided with a mounting shaft 350 , and the mounting shaft 350 is connected to the driving mechanism 200 .

[0049] The mounting shaft 350 is disposed on the end of the outer cylinder 300 opposite to the outer cover 320 , and the entire outer cylinder 300 is movably mounted on the base 100 via a bracket 450 .

[0050] Furthermore, two ends of the inner cavity 310 are in arc shape.

[0051] The two sides of the inner cavity 310 are in an arc shape. By eliminating the inner corner in the inner cavity 310, the powder is not easy to adhere to the inner corner, ensuring that the powder can be mixed more evenly.

[0055] Gear 440, corresponding to the inner gear ring 430;

[0056] A bracket 450 is installed between the gear 440 and the mounting shaft 350;

[0057] The universal coupling 460 is connected between the gear 440 and the stirring shaft 420 .

[0058] When the installation shaft 350 rotates, the gear 440 rotates around the axis of the outer cylinder 300 together with the installation shaft 350 through the bracket 450, and meshes with the inner gear ring 430 through the gear 440. At the same time, the gear 440 rotates around its own axis, and the relative position between the gear 440 and the stirring shaft 420 remains unchanged through the bracket 450. When the gear 440 rotates through the universal coupling 460, it drives the stirring shaft 420 to rotate.

The stirring blade 410 is V-shaped and can stir the powder flowing back and forth between the two ends in the inner cavity 310, and the powder is dispersed through the inclined surface 411 to improve the stirring efficiency. The inclined surfaces 411 on both sides of the V-shaped structure of the stirring blade 410 can stir the powder flowing in a circle relative to the inner cavity 310, further improving the stirring efficiency.
