[0001] The utility model relates to the technical field of metal soft magnetic powder core processing, in particular to a mixing device for improving the uniformity of metal soft magnetic powder cores. Background Technique

[0002] Metal soft magnetic powder cores are a type of soft magnetic material. They are powders made of metal or alloy soft magnetic materials and produced through special processes. Metal soft magnetic powder cores mainly include four major series: iron powder cores, iron-silicon-aluminum magnetic powder cores, high-flux magnetic powder cores, and molybdenum permalloy magnetic powder cores. Currently, with the progress of science and technology and society, higher requirements have been put forward for the development of various scientific and technological fields. In today's society, high precision, high sensitivity, large capacity, and miniaturization are the general requirements and development directions for various electronic products. This is also the requirement and development direction for soft magnetic materials widely used in various electronic products. Therefore, during the processing and production of metal soft magnetic powder cores, higher requirements are also placed on the uniformity of the mixing of their raw materials.

[0003] However, the stirring mechanisms in existing mixing devices are all fixedly arranged and rotate 360° around a center, unable to change the stirring range, resulting in certain limitations in stirring.

Detailed Description of the Embodiment

[0030] In order to have a clearer understanding of the technical features, objectives, and effects of the present invention, the specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0031] Embodiment 1

[0032] A preferred embodiment of a mixing device for improving the uniformity of metal soft magnetic powder cores provided by the present invention is as Figures 1 to 4 shown:

[0033] A mixing device for improving the uniformity of metal soft magnetic powder cores includes:

[0034] An outer cylinder 1, with an auxiliary plate 5 fixedly installed on the top surface of the outer cylinder 1, a support 3 fixedly installed at the bottom of the auxiliary plate 5, and a base 4 fixedly installed at the bottom of the support 3. By installing the support 3 and the base 4 installed at the bottom of the support 3, the stability of the entire device can be enhanced;

[0035] An inner cylinder 2, arranged inside the outer cylinder 1;

[0036] A stirring component 7, penetrating through the outer cylinder 1 and the inner cylinder 2;

[0037] The micro-vibration assembly 8 is installed between the outer cylinder 1 and the inner cylinder 2.

[0038] The stirring assembly 7 includes:

[0039] A motor 71 is arranged on the right side of the outer cylinder 1. A short shaft 72 is fixedly installed at the output end of the motor 71. The right end of the short shaft 72 sequentially passes through the right side surfaces of the outer cylinder 1 and the inner cylinder 2 movably and extends into the inner cylinder 2.

[0040] A pin block 75 is clamped and arranged in a rectangular opening 78 formed on the outer wall of the short shaft 72. A stirring shaft 73 is fixedly installed on the end face of the pin block 75. Stirring rods 74 are fixedly installed on the outer wall of the stirring shaft 73.

[0041] Here, the height of the pin block 75 is greater than the height of the inner wall of the rectangular opening 78. This setting is to enable the pin block 75 to have a certain range of movement during the rotation of the short shaft 72, and then enable the stirring rods to have a stirring variation range.

[0042] In the specific implementation process, when the motor 71 is started to rotate the short shaft 72, due to the setting of the pin block 75, the stirring shaft 73 will drive the stirring rods 74 to rotate to achieve the stirring purpose. Due to the setting between the pin block 75 and the short shaft 72, the stirring rods 74 will have a change in the stirring range, enhancing the stirring efficiency.

[0043] In this embodiment, a motor base 6 is fixedly installed on the lower surface of the motor 71. The motor base 6 is fixedly installed on the right side surface of the outer cylinder 1. By installing the motor base 6, the motor 71 can be stably installed, facilitating the normal operation of the motor 71.

[0044] Furthermore, a sliding rod 76 is fixedly installed on the surface of the pin block 75. The sliding rod 76 is slidably arranged in a rectangular groove 79 formed on the inner wall of the rectangular opening 78. A first spring 77 is fixedly installed between the sliding rod 76 and the rectangular groove 79. Through the cooperation of the sliding rod 76 and the first spring 77, vibration of the pin block 75 can be achieved, so that the stirring rods 74 can vibrate, preventing the raw materials to be stirred from adhering to the stirring rods 74 and affecting the stirring effect.

[0045] Embodiment 2

[0046] On the basis of the above implementation scheme, the micro-vibration assembly 8 includes:

[0047] An L-shaped plate 81, one end of which is fixedly arranged with the inner cylinder 2, and the other end is slidably arranged in a chute formed on the surface of the auxiliary plate 5;

[0048] A second spring 82, one end of which is fixedly installed on the lower surface of the L-shaped plate 81, and the other end is fixedly installed on the bottom of the inner wall of the chute.

[0049] In the specific implementation process, when the stirring rod 74 rotates to the lowest position during rotation, due to the setting of the pin block 75, the stirring rod 74 at the lowest position will impact the bottom of the inner wall of the inner cylinder 2. Then, with the setting of the L-shaped plate 81 and the second spring 82, the inner cylinder 2 can vibrate slightly up and down to vibrate and mix the raw materials, cooperate with the stirring work of the stirring rod 74, and make the stirring more sufficient.

[0050] Working principle: First, pour the raw materials to be stirred into the inner cylinder 2, and then start the motor 71 to rotate the short shaft 72. Since the short shaft 72 is clamped with the pin block 75 and the sliding rod 76 is set at the same time, the pin block 75 can be rotated under the rotation of the short shaft 72. Under the rotation of the pin block 75, the stirring shaft 73 can be rotated, and finally the stirring rod 74 can perform the stirring work. During the rotation of the pin block 75, it will be affected by the downward gravity. Since the height of the pin block 75 is greater than the height of the inner wall of the rectangular inlet 78, the pin block 75 can drive the stirring rod 74 to move downward to change the stirring range. When the stirring rod 74 moves downward, it will impact the bottom of the inner wall of the inner cylinder 2. Then, with the setting of the L-shaped plate 81 and the second spring 82, the up and down vibration of the inner cylinder 2 can be realized, so that the principle can be mixed again, and cooperate with the work of the stirring rod 74. Here, with the setting of the first spring 77, the vibration of the stirring rod 74 can be strengthened, preventing the raw materials from adhering to the stirring rod 74 and avoiding affecting the stirring work of the stirring rod 74.

[0051] The above is only the schematic specific implementation manner of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention. Moreover, it should be noted that the components of the present invention are not limited to the above overall application. Each technical feature described in the specification of the present invention can be selected and used alone according to actual needs or selected and combined in multiple items. Therefore, the present invention should naturally cover other combinations and specific applications related to the inventive points of this case.
