[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other alternative implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] like Figures 1 to 4As shown, in one embodiment of a mixing device for dielectric ceramic powder, the mixing device includes a support base 10, a drive motor 20, a first rotating gear 30, a second rotating gear 50, and a mixing assembly 40. The drive motor 20 is mounted on the top of the support base 10 and has a drive shaft. The first rotating gear 30 is fixed to the drive shaft and can be driven to rotate by the drive motor 20. The second rotating gear 50 is movably disposed on the top of the support base 10. The mixing assembly 40 is disposed between the first rotating gear 30 and the second rotating gear 50 along the width direction of the support base 10, and the mixing assembly 40 includes a mixing cylinder 41 and a rotating gear ring. 42, wherein the mixing cylinder 41 includes a cylinder body 411 and a sealing cover 412. The surface of the cylinder body 411 is provided with a feed port 4111, which is used to feed the medium ceramic powder and liquid (such as water or organic solvent) into the cylinder body 411 and to remove the medium ceramic powder and liquid from the feed port 4111 after they are mixed. The sealing cover 412 can close the feed port 4111. One end of the cylinder body 411 is movably connected to the top of the support base 10. In the direction away from this end of the cylinder body 411, the rotating gear ring 42 is sleeved around the circumference of the cylinder body 411 and fixed to the surface of the cylinder body 411, and also meshes with the first rotating gear 30 and the second rotating gear 50.

[0022] In this embodiment, after different types of media ceramic powder and liquid (water or organic solvent) are put into the cylinder 411 through the feed port 4111, the feed port 4111 is sealed by the sealing cap 412 to prevent leakage; the drive motor 20 is started and drives the first rotating gear 30 to rotate. Since the first rotating gear 30, the rotating gear ring 42 and the second rotating gear 50 mesh with each other, the rotating gear ring 42 drives the mixing cylinder 41 to rotate coaxially, and the different types of media ceramic powder and liquid in the mixing cylinder 41 are fully mixed during the rotation.

[0023] like Figure 2 As shown, in order to improve the stability of the first rotating gear 30, the mixing device for the dielectric ceramic powder also includes a first gear mounting member 60 installed on the top of the support base 10. The drive shaft passes through the first gear mounting member 60 and is movably connected to the first gear mounting member 60. The first rotating gear 30 is located between the first gear mounting member 60 and the drive motor 20, so that both ends of the first rotating gear 30 are supported.

[0024] like Figure 1 As shown, in order to install the second rotating gear 50, the mixing device for the medium ceramic powder also includes a second gear mounting member 70 installed on the top of the support base 10. The second gear mounting member 70 is U-shaped, and the second rotating gear 50 is installed on the second gear mounting member 70. The two ends of the second rotating gear 50 are movably connected to the second gear mounting member 70.

[0025] In this embodiment, the support base 10 includes a support body 11 and a plurality of support feet 12 disposed at the bottom of the support body 11. The support body 11 has a plate-like structure and its top surface is flat. The aforementioned drive motor 20, first rotating gear 30, second rotating gear 50 and mixing component 40 are all mounted on the top surface of the support body 11.

[0026] Furthermore, in combination Figure 3 and Figure 4 In order to improve the mixing efficiency of different types of ceramic powder and liquid, in this embodiment, the mixing cylinder 41 also includes a stirring body 413. The stirring body 413 is disposed inside the cylinder 411 along the length direction of the cylinder 411, and the two ends of the stirring body 413 are movably connected to the side wall of the cylinder 411.

[0027] Specifically, in Figure 4 In this embodiment, the mixing body 413 includes a movable shaft 4131, two connecting wheels 4132, and multiple stirring rods 4134. The movable shaft 4131 has a first end and a second end that are far apart from each other. The first end of the movable shaft 4131 is movably connected to one side wall of the cylinder 411, and the second end of the movable shaft 4131 is movably connected to the other side wall of the cylinder 411. One connecting wheel 4132 is located near the first end of the movable shaft 4131, and the other connecting wheel 4132 is located near the second end of the movable shaft 4131. Multiple stirring rods 4134 are arranged between the two connecting wheels 4132 and are parallel to each other. Preferably, the connecting wheel 4132 has multiple connecting arms 4133, which are evenly distributed around the circumference of the movable shaft 4131. Each connecting arm 4133 is connected to at least two stirring rods 4134. In this embodiment, during the rotation of the mixing cylinder 41, the stirring rods 4134 can fully stir the media ceramic powder and liquid, improving the mixing efficiency of the media ceramic powder and liquid.

[0028] In some other embodiments, the stirring body 413 includes a movable shaft 4131 and stirring parts. The first end of the movable shaft 4131 is movably connected to one side wall of the cylinder 411, and the second end of the movable shaft 4131 is movably connected to another side wall of the cylinder 411. There are multiple stirring parts, which are fixed perpendicularly to the surface of the movable shaft 4131 along the length direction of the movable shaft 4131. During the rotation of the mixing cylinder 41, the stirring parts can fully stir the medium ceramic powder and liquid, thereby improving the mixing efficiency of the medium ceramic powder and liquid.

[0029] Preferred, such as Figure 3As shown, in order to further improve the mixing efficiency of the dielectric ceramic powder and the liquid, the inner wall of the cylinder 411 has multiple stirring teeth 414 in the circumferential direction. During the rotation of the mixing cylinder 41, the dielectric ceramic powder comes into contact with the stirring teeth 414, and the stirring teeth 414 can stir and mix the dielectric ceramic powder and the liquid, thereby improving the mixing efficiency.

[0030] Furthermore, such as Figure 2 As shown, in order to provide support for the end of the mixing cylinder 41 that is away from the rotating gear ring 42 during rotation, the mixing cylinder 41 also includes a rotating shaft 4112 disposed at one end of the cylinder body 411; the mixing device for the dielectric ceramic powder also includes a support assembly 90 that is movably connected to the rotating shaft 4112; on the one hand, the support assembly 90 can support the rotating shaft 4112; on the other hand, after the dielectric ceramic powder and liquid are mixed, the rotating shaft 4112 of the mixing cylinder 41 can be released from the restriction of the support assembly 90, making it convenient for the mixing cylinder 41 to remove the dielectric ceramic powder.

[0031] Specifically, in Figure 2 In the support assembly 90, there are a support frame 91, a first engaging member 92, and a second engaging member 93. The support frame 91 has a gate-shaped structure and is fixed to the top of the support base 10. The first engaging member 92 is installed on the top of the support frame 91 and has a first slot (not shown) adapted to the rotating shaft 4112. The cross-sectional shape of the first slot is semi-circular. The second engaging member 93 is disposed opposite to the first engaging member 92 and is detachable from it. The second engaging member 93 has a second slot (not shown) adapted to the rotating shaft 4112 and has a semi-circular cross-sectional shape. The second slot and the first slot can form a rotating hole, allowing the rotating shaft 4112 to pass through the rotating hole. When the mixing cylinder 41 rotates, the rotating shaft 4112 rotates coaxially with the rotating hole. Preferably, a bearing is provided between the rotating hole and the rotating shaft 4112 to further facilitate the rotation of the rotating shaft 4112.

[0032] In addition, the second locking member 93 is fixed to the top of the first locking member 92 by a threaded connection. When disassembling the mixing cylinder 41, the second locking member 93 and the first locking member 92 are separated, so that the rotating shaft 4112 of the mixing cylinder 41 can be freed from the restriction of the rotating hole. When installing the mixing cylinder 41, the second locking member 93 and the first locking member 92 are connected and fixed.

[0033] Furthermore, such as Figure 1 As shown, to facilitate the collection and storage of the mixed dielectric ceramic powder, the mixing device for the dielectric ceramic powder also includes a collection box 80, which is used to collect the mixed dielectric ceramic powder. Preferably, the collection box 80 is located between the top of the support base 10 and the mixing cylinder 41, and can be pulled out from one side of the support frame 91.

[0034] Finally, it should be noted that if any directional indication (such as up, down, left, right, front, back, etc.) is involved in the embodiments of this application, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0035] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.
