[0039] Reference Figures 1 to 5 The following are several embodiments of the powder-mixing mechanism of this utility model.

[0040] like Figures 1 to 5As shown, the powder leveling mechanism of this utility model embodiment includes a powder collecting component 100, a conveying shaft 200, a powder conveying assembly 300, and a first driving component 400. The powder collecting component 100 is provided with a powder collecting trough 110, which is used to carry powder. The conveying shaft 200 is arranged in the powder collecting trough 110 along the length direction of the powder collecting trough 110. A conveying blade 210 is provided on the conveying shaft 200. The powder conveying assembly 300 includes a powder conveying component 310, which is provided with a feeding port 311. The feeding port 311 is located above the powder collecting trough 110, and the powder conveying component 310 conveys powder to the powder collecting trough 110 through the feeding port 311. The first driving component 400 is connected to the conveying shaft 200 and is used to drive the conveying shaft 200 to rotate, so that the conveying blade 210 drives the powder in the powder collecting trough 110 to be conveyed along the length direction of the powder collecting trough 110.

[0041] The feed inlet 311 is located above the powder collection trough 110. The powder conveying assembly 300 conveys powder to the powder collection trough 110 through the feed inlet 311, causing the powder to accumulate below the feed inlet 311. The first driving member 400 drives the conveying shaft 200 to rotate, and the conveying blade 210 moves accordingly, thereby driving the powder to be conveyed in the length direction of the powder collection trough 110. Under the action of the conveying blade 210, the powder moves in the length direction of the powder collection trough 110, forming a longitudinal flow, avoiding local accumulation of powder, and making the powder evenly distributed in the length direction of the powder collection trough 110 so that the powder in the powder collection trough 110 can be directly utilized.

[0042] In related technologies, the recovered powder is usually piled up locally, for example, below the feed inlet, which is not conducive to evenly spreading the recovered powder on the diaphragm. In this embodiment of the invention, the rotation of the conveying shaft 200 makes the powder evenly distributed along the length of the powder collection trough 110 under the action of the conveying blade 210. A diaphragm can be set below the powder collection trough 110, and the powder in the powder collection trough 110 can be poured out to make the recovered powder adhere to the diaphragm. Since the powder is evenly distributed along the length of the powder collection trough 110, it is beneficial for the powder to be evenly spread on the diaphragm.

[0043] like Figures 1 to 5 As shown, in some embodiments, the conveying blade 210 extends spirally along the length of the powder collection trough 110. The conveying blade 210, through its spiral extension structure, converts rotational motion into continuous axial thrust to push the powder along the length of the powder collection trough 110.

[0044] like Figures 1 to 5As shown, in some embodiments, the conveying blade 210 includes a first conveying blade 211 and a second conveying blade 212. The first conveying blade 2110 and the second conveying blade 212 are arranged sequentially along the length direction of the powder receiving trough 110, and the first conveying blade 211 and the second conveying blade 212 are symmetrically arranged with respect to the feed inlet 311. The first conveying blade 211 and the second conveying blade 212 extend in opposite directions, and the conveying shaft 200 rotates in the same direction, so that the first conveying blade 211 and the second conveying blade 212 generate axial thrust in opposite directions, thereby allowing the powder to move in two different directions, which is beneficial for the powder to be evenly distributed in the length direction of the powder receiving trough 110.

[0045] If only the first conveying blade 211 is provided, the powder can only be conveyed to one end of the powder collection trough 110 along the length of the spiral bar via the first conveying blade 211, resulting in a single direction of movement. However, if the first conveying blade 211 and the second conveying blade 212 are provided simultaneously, and the spiral extension directions of the first conveying blade 211 and the second conveying blade 212 are opposite, then the powder will be conveyed to both ends of the powder collection trough 110 along the length of the spiral bar via the first conveying blade 211 and the second conveying blade 212, which is more conducive to the uniform distribution of the powder along the length of the powder collection trough 110. The first conveying blade 211 and the second conveying blade 212 are both provided on the conveying shaft 200. The conveying shaft 200 rotates in one direction to apply thrust to the powder in different directions, reducing the number of driving components of the conveying shaft 200 and improving the integration of the powder leveling device. Generally, the first driving component 400 is a motor.

[0046] like Figures 1 to 5 As shown, in some embodiments, the powder homogenizing mechanism further includes a recovery component 500, which is provided with a recovery trough 510 for collecting powder scattered during the powder shaking process; the powder conveying assembly 300 further includes a powder conveying drive component, which includes a first pipe 312 disposed within the powder collection trough 110 along its length; the first pipe 312 communicates with the recovery trough 510; the powder conveying drive component is used to drive the powder in the recovery trough 510 to be conveyed through the first pipe 312 to the feed inlet 311 for homogenizing the recovered powder; the first pipe 312 is ... powder conveying drive component is used to drive the powder in the recovery trough 510 to be conveyed through the first pipe 312 to the feed inlet 311 for homogenizing the recovered powder; the first pipe 312 is disposed within the powder collection trough 110 along its length; the powder conveying drive component is used to drive the powder in the recovery trough 510 to be conveyed through the first pipe 312 to the feed inlet 311 for homogenizing the recovered powder; the powder conveying drive component is used to drive the The powder trough 110 is positioned along its length within the powder collection trough 110, allowing the powder in the recovery trough 510 to be transferred to the middle of the powder collection trough 110 via the first pipe 312, facilitating powder homogenization. If the powder is transported to the end of the powder collection trough 110, it may accumulate in the dead corners of the powder collection trough 110, which is not conducive to powder reuse. In this embodiment, multiple feed ports 311 are provided, and the multiple feed ports 311 are located above the middle of the powder collection trough 110, so that the powder in the recovery trough 510 can be transferred to the middle of the powder collection trough 110 for homogenization via the feed ports 311.

[0047] like Figures 1 to 5As shown, in some embodiments, the powder-spreading mechanism further includes a second driving member 600 and a powder-spreading rod 700. The powder-spreading rod 700 is arranged along the length direction of the powder-collecting trough 110 with a powder-collecting member 100. The powder-spreading rod 700 includes an outer cylinder 710 and an inner shaft 720, with the inner shaft 720 disposed inside the outer cylinder 710. A material inlet 111 is provided at the bottom of the powder-collecting trough 110, a material inlet 711 is provided above the outer cylinder 710 and is located below the material inlet 111, and a material outlet 712 is provided below the outer cylinder 710. The second driving member 600 is connected to the inner shaft 720 and is used to drive the inner shaft 720 to rotate.

[0048] Understandably, under the action of the conveyor shaft 200, the powder is evenly distributed along the length of the powder collection trough 110 at the bottom of the trough 110, and enters the outer cylinder 710 through the feed port 111 and the feed inlet 711; the inner shaft 720 is located inside the outer cylinder 710 and carries the powder. Under the action of the second drive member 600, the inner shaft 720 rotates, so that the powder on the inner shaft 720 can fall through the discharge port 712; the powder spreading rod 700 plays a temporary role in storing the powder, so that the powder falls onto the diaphragm below through the inner shaft 720. The progress of powder spreading can be controlled by controlling the rotation speed of the inner shaft 720; generally, the second drive member 600 is a motor.

[0049] like Figures 1 to 5 As shown, in some embodiments, multiple temporary storage slots 721 are spaced apart on the outer periphery of the inner shaft 720. The temporary storage slots 721 serve to hold powder. The temporary storage slots 721 extend along the length of the powder collection slot 110, allowing powder evenly distributed along the length of the powder collection slot 110 to enter the outer cylinder 710 through the feed inlet 111 and the feed port 711, and be temporarily stored in the temporary storage slots 721. As the inner shaft 720 rotates, the powder in the temporary storage slots 721 is sprinkled onto the diaphragm below the powder collection slot 110 through the discharge port 712. The second driving member 600 drives the inner shaft 720 to rotate, and since the inner shaft 720 is provided with multiple temporary storage slots 721, the powder is sprinkled multiple times during one rotation of the inner shaft 720. In this embodiment, three temporary storage slots 721 are provided, therefore, the powder is sprinkled three times during one rotation of the inner shaft 720.

[0050] like Figures 1 to 5 As shown, in some embodiments, a membrane receiving space 120 is formed below the discharge port 712; a guide plate 130 is provided at the bottom of the powder receiving trough 110, which is used to guide the powder flowing out of the discharge port 712 to the receiving space 120; during operation, the membrane is placed in the receiving space 120, the powder in the powder receiving trough 110 is sprinkled out by the powder spreading rod 700, and the guide plate 130 guides the powder to flow to the membrane, so that the powder flows accurately to the membrane, improving the utilization rate of the powder and reducing the waste of powder.

[0051] like Figure 2As shown, in some embodiments, the recycling tank 510 is located below the receiving space 120, and the membrane is arranged in a V-shape within the receiving space 120. Excess powder after passing through the membrane flows from both ends of the membrane into the recycling tank 510 for further recycling.

[0052] like Figures 1 to 5 As shown, in some embodiments, the powder conveying component 310 is connected to the recycling tank 510; the powder conveying drive component is used to drive the powder in the recycling tank 510 to be conveyed through the powder conveying component 310 to the feed port 311, so as to perform a uniform powder operation on the powder through the conveying shaft 200, which facilitates the recycling of the powder.

[0053] like Figures 1 to 5 As shown, in some embodiments, the powder conveying component 310 includes a second pipe 313, which is arranged along the direction from the recovery component 500 to the powder receiving component 100, and the second pipe 313 is connected to the recovery tank 510 and the powder receiving tank 110; the powder conveying drive component is used to drive the powder in the recovery tank 510 to be conveyed to the powder receiving tank 110 through the second pipe 313; the powder in the recovery tank 510 can be vertically conveyed through the second pipe 313 so that the powder recovered by the recovery tank 510 can enter the powder receiving tank 110 for powder homogenization operation, and be spread onto the membrane by the powder spreading rod 700 for secondary use.

[0054] like Figures 1 to 5 As shown, in some embodiments, the powder conveying drive includes a powder conveying motor and a powder conveying screw 321. The powder conveying motor is mounted on the powder receiving component 100 and connected to the powder conveying screw 321. The powder conveying screw 321 is disposed within the second pipe 313, and the first pipe 312 and the second pipe 313 are connected. The powder leveling mechanism also includes a recovery screw 530 and a recovery motor 520. The recovery screw 530 is disposed within the recovery trough 510. The recovery motor 520 is mounted on the recovery component 500 and connected to the recovery screw 530, so that the powder in the recovery trough 510 is transferred to the second pipe 313. The powder conveying motor drives... The rotating powder conveying screw 321 transfers the powder in the second tube 313 to the first tube 312. With the continuous operation of the powder conveying motor, the second tube 313 continues to convey powder to the first tube 312, causing the powder in the first tube 312 to be squeezed to the feed inlet 311 and fall from the feed inlet 311 onto the conveying shaft 200. The rotating conveying shaft 200 causes the conveying blade 210 to carry the powder along the length of the powder collection trough 110, so that the powder is evenly distributed in the powder collection trough 110. The powder falls from the feed inlet 111 to the powder spreading rod 700 and is spread onto the diaphragm by the powder spreading rod 700.
