[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] In order to solve the problem that the powder material dividing device in the prior art has low efficiency in dividing various powder materials, the utility model provides a dividing device.

[0021] Please refer to Figure 1 As shown, the dispensing device includes a shell body 10 and a conveying assembly 20; wherein, the shell body 10 has a conveying cavity 11 for powder flow, and the shell body 10 is respectively provided with a feed port 12 and a plurality of discharge ports 13, and the feed port 12 and the plurality of discharge ports 13 are respectively connected with the conveying cavity 11; the conveying assembly 20 can be movably arranged in the conveying cavity 11 to transport the powder in the conveying cavity 11, and the conveying cavity 11 has a plurality of conveying openings 110 arranged at intervals, and the plurality of conveying openings 110 are arranged one by one with the plurality of discharge ports 13, so that the powder in the conveying cavity 11 can be selectively passed through a conveying opening 110 and then discharged from the discharge port 13 corresponding to the conveying opening 110.

[0022] By applying the technical solution of this embodiment, multiple discharge ports 13 correspond to multiple different target positions, and powders from different sources are fed into the conveying cavity 11 of the shell body 10 from the feed port 12. Under the transportation of the conveying component 20, the powders flow to the discharge port 13 through the conveying break 110 at the discharge port 13 corresponding to the powder, and flow out from the discharge port 13, so as to realize the distribution of powders from multiple different sources to different target positions in turn, so as to meet different production needs, greatly improve the production efficiency, and thus solve the problem of low efficiency of the powder distribution device in the prior art in distributing multiple powders; at the same time, the overall structure of the device is simple and easy to use, which is conducive to simplifying the process layout and saving production costs.

[0023] Specifically, the conveying assembly 20 includes a rotating shaft 21 and a plurality of spiral blades 22; wherein the rotating shaft 21 is rotatably disposed in the housing body 10; the plurality of spiral blades 22 are arranged around the rotating shaft 21 at intervals along the axial direction of the rotating shaft 21, and a first preset spacing L1 is provided between two adjacent spiral blades 22, so that a conveying opening 110 is formed between the outer peripheral surface of the rotating shaft 21 between the two adjacent spiral blades 22 and the inner wall of the housing body 10. The above arrangement, through the first preset spacing L1 provided between the two adjacent spiral blades 22, enables the conveying opening 110 to have a length of the first preset spacing L1, so that a certain amount of powder can be delivered from the corresponding discharge port 13 through the conveying opening 110.

[0024] like Figure 1As shown, the opening edge of each discharge port 13 along the extension direction of the shell body 10 has a first end 131 and a second end 132 that are relatively arranged. In two adjacent spiral blades 22, one end of one spiral blade 22 is close to the other spiral blade 22 and is arranged corresponding to the first end 131, and one end of the other spiral blade 22 is located between the first end 131 and the second end 132 and is arranged close to the second end 132. In the above arrangement, in two adjacent sections of the spiral blade 22, one end of one section of the spiral blade 22 is arranged corresponding to the first end 131 of the discharge port 13, so that when the powder is transported from the feed port 12 to the corresponding discharge port 13 through the spiral blade 22, the powder can accurately enter the discharge pipe from the opening of the discharge port 13 corresponding thereto after passing through the conveying break 110 and be delivered from the discharge pipe; and one end of the other section of the spiral blade 22 is located between the first end 131 and the second end 132 and is arranged close to the second end 132, so that the powder is blocked when flowing in the conveying cavity 11, so as to prevent one end of the other section of the spiral blade 22 from being too close to the first end 131, resulting in the powder being unable to transition from the conveying break 110 to the discharge port 13, or one end of the other section of the spiral blade 22 from being too far from the second end 132, resulting in part of the powder not flowing from the conveying break 110 to the discharge port 13.

[0025] Specifically, each section of the spiral blade 22 has a second preset spacing L2 with the inner wall of the shell body 10, and the second preset spacing L2 satisfies: 5mm≤L2≤10mm. The above arrangement, by maintaining a gap of the second preset spacing L2 between each section of the spiral blade 22 and the inner wall of the shell body 10, facilitates the situation that each section of the spiral blade 22 is too close to the inner wall of the shell body 10 when conveying powder, affecting normal production; or each section of the spiral blade 22 is too far from the inner wall of the shell body 10 when conveying powder, causing part of the powder to flow from the gap between the spiral blade 22 and the inner wall of the shell body 10 to the next conveying break 110, thereby affecting the normal progress of the material separation process.

[0026] Optionally, there is only one feed port 12, which is arranged at one end of the shell body 10 along the extension direction of the shell body 10, and the feed port 12 is located above the discharge port 13 in the vertical direction; in this way, powders from different sources are put into a feed port 12 and conveyed to the corresponding conveying port 110 and the discharge port 13 through the spiral blades 22, and then discharged from the discharge port 13.

[0027] Optionally, there are two feed ports 12, which are respectively arranged at opposite ends of the housing body 10 along its extension direction, and the feed ports 12 are located above the discharge port 13 in the vertical direction. In this way, the above arrangement can selectively put the powder into one of the two discharge ports 13 closest to it, so as to facilitate the powder to be sent out from the corresponding discharge port 13.

[0028] Optionally, there are at least three feed ports 12, which are arranged on the housing body 10 at intervals along the extension direction of the housing body 10, and each feed port 12 is arranged between two adjacent discharge ports 13 corresponding thereto, and the discharge ports 13 are all located below the feed port 12 along the vertical direction. The above arrangement prevents the feed port 12 from being arranged relative to the discharge port 13 and affecting the normal material distribution operation by arranging the feed port 12 between two adjacent discharge ports 13 corresponding thereto.

[0029] Specifically, the material distributing device further includes a driving component 30, which is disposed at one end of the housing body 10 along its extension direction and is drivingly connected to the end of the rotating shaft 21. With the above arrangement, the driving component 30 can drive the rotating shaft 21 to rotate clockwise or counterclockwise, thereby causing the powder to flow in the reverse direction from one end to the other end of the housing body 10, or vice versa.

[0030] In this embodiment, the driving component 30 is a driving motor.

[0031] Optionally, a first control valve 121 is provided at the feed port 12 to control the opening or closing of the feed port 12; thus, after selecting the corresponding feed port 12, other feed ports 12 can be closed by the first control valve 121 to prevent other substances from entering the conveying cavity 11 from the feed port 12 during the material distribution process.

[0032] Optionally, each discharge port 13 is provided with a second control valve 14 for controlling the opening or closing of each discharge port 13. With the above arrangement, after powders from different sources select the corresponding discharge ports 13, other discharge ports 13 can be closed by controlling the second control valve 14 to prevent the powders from flowing out of other discharge ports 13.

[0033] Specifically, the first preset spacing L1 satisfies: 100 mm ≤ L1 ≤ 200 mm. The above setting is to prevent the spacing between two adjacent spiral blades 22 from being too large, which may cause part of the powder to flow to the next conveying break 110 under the conveying of the spiral blades 22, or the spacing between two adjacent spiral blades 22 from being too small, which may cause part of the powder to fail to flow from the conveying break 110 to the discharge port 13.

[0034] Specifically, the housing body 10 is a hollow rod-shaped structure.

[0035] Optionally, an observation port 15 is provided on the shell body 10 , and a transparent plate is detachably provided in the observation port 15 for observing the flow state of the powder in the conveying cavity 11 .

[0036] In this embodiment, the material distribution device further includes a PCL system, which is controllably connected to the driving component 30, the first control valve 121 and the second control valve 14 respectively.

[0037] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0038] The material distribution device includes a shell body and a conveying component; wherein, the shell body has a conveying cavity for powder flow, and the shell body is respectively provided with a feed port and a plurality of discharge ports, and the feed port and the plurality of discharge ports are respectively connected with the conveying cavity; the conveying component can be movably arranged in the conveying cavity to transport the powder in the conveying cavity, and the conveying cavity has a plurality of conveying openings arranged at intervals, and the plurality of conveying openings are arranged one by one corresponding to the plurality of discharge ports, so that the powder in the conveying cavity can be selectively passed through a conveying opening and then discharged from the discharge port corresponding to the conveying opening. In the above arrangement, multiple discharge ports correspond to multiple different target positions. Powders from different sources are fed from the feed port into the conveying cavity of the outer shell body. Under the transportation of the conveying component, the powders flow to the discharge port through the conveying break at the discharge port corresponding to the powders, and flow out from the discharge port, so as to distribute powders from multiple different sources to different target positions in turn to meet different production needs, greatly improve production efficiency, and thus solve the problem of low efficiency of powder distribution devices in the prior art in distributing multiple powders. At the same time, the overall structure of the device is simple and easy to use, which is conducive to simplifying the process layout and saving production costs.
