Description

Technical Field

[0001] This utility model belongs to the field of electronic material processing technology, and specifically relates to a soft magnetic ferrite powder mixing device. Background Technology

[0002] When magnetization occurs at a Hc value of no more than 1000 A / m, such materials are called soft magnetic materials. Soft magnetic ferrites are ferrimagnetic oxides with Fe2O3 as the main component, produced using powder metallurgy. During the pressing and molding process of soft magnetic ferrites, in order to reduce the friction between the powder and the mold cavity and extend the mold's service life, the powder and lubricant need to be mixed evenly beforehand to ensure that the powder has good flowability.

[0003] However, during the mixing process, the lubricant will accumulate at the bottom of the processing chamber, causing uneven mixing and stirring, and the mixture is prone to separation during stirring.

[0004] To address the problems mentioned in the background above, we propose a soft magnetic ferrite powder mixing device. Utility Model Content

[0005] The purpose of this invention is to provide a soft magnetic ferrite powder mixing device, which has the advantages of preventing bottom accumulation and ensuring uniform mixing.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a soft magnetic ferrite powder mixing device, comprising a processing chamber, a rotating shaft B bolted to the left side of the processing chamber, a bracket B rotatably connected to the middle of the surface of the rotating shaft B, a rocker arm B fixedly sleeved to the left side of the rotating shaft B, a connecting rod bolted to the bottom of the bracket B, a connecting frame bolted to the front and rear ends of the left side of the connecting rod, a bracket A bolted to the bottom inside the connecting frame, a rotating shaft A rotatably connected inside the bracket A, a rocker arm A fixedly sleeved to the right side of the rotating shaft A, a bracket C bolted to the top of the connecting frame, a rocker plate rotatably connected to the right side of the bracket C, a limit mechanism provided inside the rocker plate, and a stirring mechanism provided at the top of the processing chamber.

[0007] The above technical solution is adopted: the rotating shaft A drives the rocker arm A to rotate, the rocker arm A drives the rocker plate to swing back and forth, the rocker plate drives the rocker arm B to rotate, the rocker arm B drives the rotating shaft B to rotate, and the rotating shaft B drives the processing chamber to rotate. During the mixing process in the mixing chamber, the processing chamber swings back and forth periodically to ensure that the powder can be fully rolled, collided and mixed in the chamber. This avoids the accumulation of lubricant in specific areas due to differences in gravity or centrifugal force, and eliminates the mixing blind spots at both ends or edges of the cylinder in traditional unidirectional rotation.

[0008] The present invention is further configured such that the stirring mechanism includes a vertical plate, the bottom of which is bolted to the left side of the top of the processing chamber, a C-shaped plate bolted to the right side of the vertical plate, a motor B bolted to the top of the C-shaped plate, a rotating rod fixedly sleeved at the bottom of the motor B, and the top of the rotating rod surface rotatably connected to the top of the C-shaped plate, a horizontal bevel gear A fixedly sleeved on the surface of the rotating rod near the top of the C-shaped plate, a vertical bevel gear meshing on the left side of the horizontal bevel gear A, and the left side of the vertical bevel gear rotatably connected to the middle of the left side inside the C-shaped plate, a horizontal bevel gear B meshing at the bottom of the vertical bevel gear, a rotating cylinder fixedly sleeved inside the horizontal bevel gear B, and the top of the rotating cylinder surface rotatably connected to the bottom of the C-shaped plate, with the bottom of the rotating rod surface penetrating the interior of the rotating cylinder, a stirrer A bolted to the bottom of the rotating rod, stirring blades A bolted to both sides of the stirrer, a stirrer B bolted to the bottom of the rotating cylinder, and stirring blades B bolted to both sides of the bottom of the stirrer B and the rotating cylinder surface.

[0009] The above technical solution employs a stirring mechanism. Motor B rotates, driving a rotating rod to rotate, which in turn drives agitator A to rotate. Agitator A then drives stirring blade A to rotate and stir. The rotating rod drives horizontal bevel gear A to rotate, which in turn drives vertical bevel gear A to rotate. The vertical bevel gear then drives horizontal bevel gear B to rotate in the opposite direction to horizontal bevel gear A. Horizontal bevel gear B drives a rotating drum to rotate, which in turn drives agitator B to rotate. The rotating drum and agitator B, in turn, drive stirring blade B to rotate. During the rotation direction switching process, the mixing effect between powder particles is enhanced. Simultaneously, the lubricant is more evenly dispersed into the powder gaps during bidirectional flow, improving mixing efficiency and material performance consistency, and reducing local agglomeration or stratification.

[0010] The present invention is further configured such that the limiting mechanism includes a sliding groove, the sliding groove passes through the rocker plate and extends in the same direction as the rocker plate, a slider A is bolted to the right side of the rocker arm A, a slider B is bolted to the left side of the rocker arm B, and both slider A and slider B are slidably installed in the sliding groove.

[0011] The above technical solution is adopted: by setting a limiting mechanism, rocker arm A drives slider A to move, slider A is slidably connected to the slide groove, slider A drives rocker plate to swing back and forth, rocker plate drives slider B to reciprocate around the lower semicircle of rocker arm B, rocker arm B drives rotating shaft B to rotate, and rotating shaft B drives processing chamber to swing back and forth.

[0012] The present invention is further configured such that a motor A is fixedly sleeved on the left side of the rotating shaft A, a frame is bolted to the bottom of the motor A, and the right side of the frame is bolted to the bottom of the left side of the connecting frame.

[0013] The above technical solution is adopted: by setting up motor A, the rotating shaft A can be driven to rotate; by setting up a frame, motor A can be stabilized.

[0014] The present invention is further configured such that a discharge port is provided at the bottom of the processing chamber, and a discharge plate is inserted through the discharge port.

[0017] The above technical solution, by setting a base, supporting legs and rotating shaft C, can stabilize the processing chamber.

[0018] The present invention is further configured such that the front of the processing chamber is rotatably connected to a feed inlet via a hinge.

[0019] The above technical solution allows for convenient material feeding by setting up a feed inlet.

[0020] The present invention is further configured such that a handle is bolted to the front of the feed inlet.

[0021] The above technical solution incorporates a handle, which allows for easy opening of the feed inlet.
