DETAILED DESCRIPTION

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0029] Reference Figure 1-4One embodiment of the utility model provides a powder mixing device for ceramic production, comprising a stirring rod 1, and the following parts:

[0030] A mixing barrel 2 and a mesh plate 3 arranged in the mixing barrel 2, wherein the mesh plate 3 can move at a fixed position in the mixing barrel 2, and the space in the mixing barrel 2 is divided from top to bottom into a screening area 4 and a mixing area 5 by the mesh plate 3, and a feeding port and a feeding port are respectively arranged at the top of the screening area 4 and the bottom of the mixing area 5;

[0031] A conveying assembly 6, under the action of which the powder can be conveyed from the mixing area 5 to the screening area 4, and the stirring rod 1 is rotatably arranged in the mixing area 5;

[0032] A material dropping channel 7 connected between the screening area 4 and the mixing area 5, and a crushing assembly 8 arranged in the material dropping channel 7, in which the powder particles cached on the mesh plate 3 can fall into the mixing area 5 through the material dropping channel 7;

[0033] Based on the above, when the powder is stirred, it is continuously conveyed from the mixing zone 5 to the screening zone 4, and the powder falling on the mesh plate 3 can directly pass through and return to the mixing zone 5 again. The plate area of ​​the mesh plate 3 is sufficiently close to the cross-sectional size of the mixing barrel 2, so that the powder falling thereon can be fully spread out, thereby helping the powder particles with standard diameters to fall quickly, and the large-diameter particles left on the mesh plate 3 can fall into the dropping channel 7, so that they can be crushed when passing through the crushing component 8, and then return to the mixing zone 5. Compared with the prior art, the mixing device provided by the utility model can fully remove powder particles with large particle diameters when mixing ceramic powders, thereby improving the quality of the final mixed powder, so as to fully reduce the impact of large-diameter powder particles in the subsequent production process; in addition, in the utility model, through the cooperation of the conveying component 6, the powder in the mixing zone 5 can also be flipped up and down during stirring, thereby further improving the mixing effect of the ceramic powder compared to the prior art.

[0034] Further, see Figure 3 and Figure 4 The conveying component 6 includes a conveying pipe 601, which is connected between the bottom of the mixing area 5 and the top of the screening area 4. The conveying pipe 601 is a hard pipe structure and can be integrated with the mixing barrel 2. The conveying component 6 also includes a spiral conveying rod 602 configured in the conveying pipe 601. By configuring power to the spiral conveying rod 602, when the powder falls into the conveying pipe 601, it can complete the simple and rapid conveying of the powder to the screening area 4.

[0035] Further, see Figure 3-5Regarding the movable setting method of the mesh plate 3, the utility model also includes an edge plate 9 fixedly arranged at the edge of the mesh plate 3, and the edge plate 9 forms a ring sleeve for the entire edge of the mesh plate 3. The peripheral side of the edge plate 9 is connected to the inner wall of the mixing barrel 2 through a flexible tube 10. The flexible tube 10 can adopt a structure such as a bellows or an organ pipe to achieve the movable effect of the mesh plate 3 in the mixing barrel 2. A material guide pipe 11 is arranged between the drop channel 7 and the inner side of the edge plate 9, so that the particles accumulated on the mesh plate 3 can eventually fall into the pouring pipe, and then enter the drop channel 7. The material guide pipe 11 is a hose structure.

[0036] Further, see Figure 3 and Figure 5 The mesh plate 3 is arranged in an inclined shape along the inner side of the plate 9, with one side of the inclination facing the pipe opening of the guide pipe 11. The inclination allows the powder particles cached thereon to be concentrated to one side, thereby better guiding them into the guide pipe 11.

[0037] Further, see Figure 3 and Figure 5 The mesh plate 3 is of an arched structure, so that its plate area can be further increased. The upper pipe opening of the conveying pipe 601 is located directly above the arched top of the mesh plate 3. The arched design allows the powder to spread out quickly when it falls onto the plate surface, thereby further promoting powder particles with qualified diameters to quickly pass through the mesh plate 3 and reach the bottom.

[0038] Further, see Figure 3-5 The pulverizing assembly 8 includes a pulverizing roller 801 disposed in the material dropping channel 7. By providing power thereto, large-diameter powder particles can be simply and conveniently crushed.

[0039] Further, see Figure 3-5 A support plate 12 is fixedly connected to the edge plate 9, and an eccentric block 13 is rotatably provided on the support plate 12. One end of the crushing roller 801 passes through the outside of the blanking channel 7 and is connected to the eccentric block 13 through a half shaft 14. When the crushing roller 801 rotates, power is provided to the eccentric block 13 through the half shaft 14 to make it rotate, thereby driving the edge plate 9 and the mesh plate 3 to shake synchronously, so as to further promote the rapid penetration of the powder on the mesh plate 3.

[0040] Further, see Figure 3 and Figure 4A plurality of spring assemblies 15 are evenly connected between the circumferential side of the plate 9 and the inner wall of the mixing barrel 2. The spring assemblies 15 can further increase the stability of the mesh plate 3 to prevent the eccentric block 13 from shaking violently and causing the mesh plate 3 to swing and hit the inner wall of the mixing barrel 2. Under the action of the spring assemblies 15 and in combination with the setting of the eccentric block 13, the mesh plate 3 can be stably vibrated or shaken at a fixed position, thereby fully promoting the penetration of the powder.

[0041] Further, see Figure 3 and Figure 4 One end of the spiral conveying rod 602 extends to the outside of the conveying pipe 601 and is connected to the crushing roller 801 through a sprocket or a pulley, so that a transmission effect is achieved between the two. The stirring rod 1 is connected to the spiral conveying rod 602 through a bevel gear assembly to achieve a transmission effect between the two. Therefore, when configuring power for the entire device, only one of them needs to be provided with power, so as to further simplify the structure of the entire device. Figure 2 As shown, the power source may be a driving motor, which is connected to the screw conveying rod 602 by transmission.

[0042] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
