[0045] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0046] According to some embodiments of this utility model, refer to Figures 1 to 10 The powder-spreading and mixing device includes a frame 100, a mixing component 200, a sealing component 300, a stirring component 400, and a powder-spreading and spraying component 500. The mixing component 200 includes a first driving component 210 and a mixing disc 220, which is rotatably connected to the frame 100. A discharge port 221 is located at the center of the bottom of the mixing disc 220. The first driving component 210 drives the mixing disc 220 to rotate around its own axis, which is in the vertical direction. The sealing component 300 includes a second driving component 310 and a plug 320. The second driving component 310 drives the plug 320 to move vertically to block or disengage from the discharge port 221. When the plug 320 blocks the discharge port 221, an annular mixing zone 330 is formed between the outer peripheral wall of the plug 320 and the inner peripheral wall of the mixing disc 220. The mixing assembly 400 is used to mix the materials located in the annular mixing zone 330. The powder spraying assembly 500 is used to spray powder into the annular mixing zone 330.

[0047] When material needs to be mixed, the second drive component 310 drives the plug 320 to move towards the discharge port 221, causing the plug 320 to seal the discharge port 221. The first drive component 210 drives the mixing disc 220 to rotate, causing the material in the mixing disc 220 to rotate around the axis of the mixing disc 220. At the same time, the powder spraying and slurry spraying component 500 sprays powder and slurry into the annular mixing zone 330. As the material moves relative to the mixing component 400 while following the movement of the mixing disc 220, the mixing component 400 mixes the material located in the annular mixing zone 330.

[0048] After mixing is complete, the second drive component 310 drives the plug 320 to disengage from the discharge port 221, allowing the material to be discharged through the discharge port 221.

[0049] This powder-spreading and mixing device can automatically spread powder while mixing materials, thereby improving production efficiency.

[0050] According to some embodiments of this utility model, refer to Figure 4 The lower end of the mixing disc 220 is provided with an annular rack 230, which is coaxially arranged with the mixing disc 220. The driving end of the first driving component 210 is provided with a gear 240, which meshes with the annular rack 230. The first driving component 210 is a drive motor, which drives the gear 240 to rotate, thereby driving the annular rack 230 and the mixing disc 220 to rotate.

[0051] According to some embodiments of this utility model, refer to Figure 2 and Figure 5 The second drive component 310 is installed on the frame 100, with the drive end of the second drive component 310 facing downwards. The drive end of the second drive component 310 is fixedly connected to the plug 320. The second drive component 310 is a cylinder. The second drive component 310 can drive the plug 320 to descend and thus block the discharge port 221, or drive the plug 320 to rise and thus disengage from the discharge port 221.

[0052] According to some embodiments of this utility model, refer to Figure 2 and Figure 5The mixing assembly 400 includes a third driving component 410 and a mixing component 420. The third driving component 410 drives the mixing component 420 to rotate around its own axis. The mixing component 420 includes a mixing disc 421 and multiple mixing rods 422. The third driving component 410 drives the mixing disc 421 to rotate around its own axis. The upper ends of the mixing rods 422 are fixedly connected to the mixing disc 421, and the multiple mixing rods 422 are distributed circumferentially along the mixing disc 421. When the first driving component 210 drives the mixing disc 220 to rotate, the third driving component 410 drives the mixing disc 421 to rotate. This dual rotation allows the mixing rods 422 to fully mix the material in the mixing disc 220. The axis of the mixing rods 422 is parallel to but does not coincide with the axis of the mixing disc 220.

[0053] According to some embodiments of this utility model, refer to Figure 1 and Figure 5 The powder mixing device also includes a lifting assembly 600, which includes a fourth drive component 610 and a lifting platform 620. The lifting platform 620 is located above the mixing tray 220 and is slidably connected to the frame 100 in the vertical direction. The fourth drive component 610 drives the lifting platform 620 to move vertically. The stirring assembly 400 is installed on the lifting platform 620. That is, the third drive component 410 is installed on the lifting platform 620. When stirring is required, the fourth drive component 610 drives the lifting platform 620 to descend, causing the stirring rod 422 to enter the annular mixing zone 330 downwards. After stirring is completed, the fourth drive component 610 drives the lifting platform 620 to rise, causing the stirring rod 422 to disengage upwards from the annular mixing zone 330, thereby facilitating the unloading of material from the mixing tray 220.

[0054] According to some embodiments of this utility model, refer to Figure 1 , Figure 6 and Figure 10 The powder spraying assembly 500 includes a housing 550, a powder hopper 530, an eighth drive component 540, a slurry tank 510, and a spray gun 520. The slurry tank 510 is installed in the housing 550 and is used to store slurry. The suction pipe of the spray gun 520 is inserted into the slurry tank 510, and the discharge port 221 of the spray gun 520 faces the annular mixing zone 330. The powder hopper 530 is installed in the housing 550, and the opening of the powder hopper 530 faces downward. The powder hopper 530 is used to store powder. The housing 550 is provided with a filter screen, which is located at the bottom of the powder hopper 530. The eighth drive component 540 is used to drive the filter screen to vibrate in the up-down direction. Multiple slurry tanks 510 and multiple spray guns 520 correspond one-to-one. The multiple slurry tanks 510 can hold various different color powders or stones. As the mixing disc 220 rotates, the spray guns 520 spray the color powder from the slurry tanks 510 into the mixing disc 220, so that the color powder can be distributed in the annular mixing zone 330, ensuring uniform mixing. The eighth drive unit 540 can drive the filter screen to vibrate, thereby spreading the material.

[0055] According to some embodiments of this utility model, refer to Figure 1 , Figure 2 and Figure 7 The powder mixing device also includes a pushing assembly 700, which includes a fifth driving component 710, a first sliding plate 720, a sixth driving component 730, and a pushing plate 740. The first sliding plate 720 is slidably connected to the frame 100. The sixth driving component 730 is installed on the first sliding plate 720. The driving end of the sixth driving component 730 faces downward and is fixedly connected to the pushing plate 740. The sixth driving component 730 is used to drive the pushing plate 740 to move in the vertical direction so as to enter or leave the annular mixing zone 330. The fifth driving component 710 is used to drive the first sliding plate 720 to move in the horizontal direction so as to drive the pushing plate 740 to move closer to or away from the discharge port 221.

[0056] Understandably, during the mixing process of the mixing disc 220, the sixth drive component 730 drives the pusher plate 740 to move upward and thus separate it from the annular mixing zone 330, so that the material in the annular mixing zone 330 can follow the rotation of the mixing disc 220. When unloading is required, the second drive component 310 drives the plug 320 to move upward and disengage from the discharge port 221. The mixing component 400 stops mixing, the powder spraying component 500 stops spraying powder, the sixth drive component 730 drives the pusher plate 740 to move downward and enter the annular mixing zone 330, and the fifth drive component 710 drives the first slide plate 720 and the pusher plate 740 to move radially along the mixing disk 220 and approach the discharge port 221, so that the pusher plate 740 can push the material to the discharge port 221. Then, the drive component drives the first slide plate 720 and the pusher plate 740 to move radially along the mixing disk 220 and move away from the discharge port 221. The first drive component 210 then drives the mixing disk 220 to rotate a certain angle, and the fifth drive component 710 then drives the first slide plate 720 and the pusher plate 740 to move radially along the mixing disk 220 and approach the discharge port 221. This cycle continues.

[0057] According to some embodiments of this utility model, refer to Figure 3 and Figure 8 The powder mixing device also includes a pressing assembly 800, which includes a seventh drive component 810, a second slide plate 820, and a pressure roller 830. The second slide plate 820 is slidably connected to the frame 100 in the vertical direction. The two ends of the pressure roller 830 are respectively inserted into and rotatably connected to the second slide plate 820. The axis of the pressure roller 830 is radial to the mixing disc 220. The seventh drive component 810 is used to drive the second slide plate 820 to move in the vertical direction, thereby driving the pressure roller 830 into or out of the annular mixing zone 330. The pressure roller 830 is used to compact the material.

[0058] Understandably, during the mixing process of the mixing disc 220, the material is mixed by the mixing component 400 and then compacted by the pressure roller 830, repeating this process to ensure uniform mixing. When material compaction is no longer required, the seventh drive component 810 drives the second slide plate 820 and the pressure roller 830 to move upward, thereby disengaging them from the annular mixing zone 330.

[0059] Preferably, the diameter of the pressure roller 830 gradually decreases towards the discharge port 221. This ensures that most of the material is close to the discharge port 221, preventing material from accumulating near the inner peripheral wall of the mixing disc 220.
