[0032] The quantitative unloading mechanism includes a shell 1; a unloading roller 2 is rotatably arranged in the shell 1; a cleaning piece 3 is swingably arranged in the shell 1, and the cleaning piece 3 abuts against the unloading roller 2; one end of a first driving rod 4 is rotatably arranged on the cleaning piece 3; one end of a second driving rod 5 is slidably arranged on the first driving rod 4, and the other end of the second driving rod 5 is rotatably arranged on the shell 1; a first driving piece 6 is arranged on the shell 1, and the first driving piece 6 is used to drive the second driving rod 5 to rotate.

[0033] In this embodiment, in order to solve the problem that the cleaning brush of the impeller in the related art can only rotate in one direction and the cleaning effect is poor, the cleaning member 3 is swingably set on the housing 1, and through the cooperation of the first driving member 6, the first driving rod 4 and the second driving rod 5, when the first driving member 6 drives the second driving rod 5 to rotate in one direction, the cleaning member 3 can be driven to swing through the first driving rod 4. During the swinging process of the cleaning member 3, the surface of the unloading roller 2 reciprocates to clean the powder material adhering to the unloading roller 2. Through the cooperation of the first driving member 6, the first driving rod 4 and the second driving rod 5, the first driving member 6 does not need to frequently rotate forward and reverse to make the cleaning member 3 swing back and forth, which ensures a good cleaning effect while increasing the service life of the equipment.

[0034] Specifically, the cleaning member 3 is swingably arranged in the housing 1 and abuts against the unloading roller 2. The first driving rod 4 is rotatably arranged on the cleaning member 3. The second driving rod 5 is slidably connected to the first driving rod 4, and the second driving rod 5 is driven to rotate by the first driving member 6. When the second connecting rod rotates, one end of the second connecting rod away from the first driving member 6 slides along the first driving rod 4, thereby driving the first connecting rod to swing, and the cleaning member 3 swings with the first driving member 6. The cleaning member 3 cleans the unloading roller 2 during the swinging process, avoiding the powder from sticking to the unloading roller 2, and improving the accuracy of quantitative unloading. During the reciprocating swinging process of the cleaning member 3, the powder on the cleaning member 3 will also fall off, reducing the adsorption of the cleaning member 3 to the powder.

[0035] Furthermore, the first driving rod 4 has a connecting part 401 and a rotating part 402, the connecting part 401 is cylindrical, the second driving rod 5 is slidably set on the connecting part 401, the rotating part 402 is a U-shaped block, the cleaning piece 3 has a through groove 301, the rotating part 402 is rotatably set on the cleaning piece 3, the rotating part 402 is located in the through groove 301, and the side wall of the rotating part 402 abuts against the through groove 301.

[0036] In this embodiment, the first driving rod 4 is composed of a connecting portion 401 and a rotating portion 402. The rotating portion 402 is rotatably arranged in the through slot 301 of the cleaning member 3, and the rotating portion 402 is in contact with the through slot 301. When the second driving rod 5 drives the first driving rod 4 to swing, the rotating portion 402 can swing in the through slot 301. At the same time, in the side wall direction of the rotating portion 402, the first driving rod 4 and the cleaning member 3 do not move relative to each other, so that the cleaning member 3 can swing stably. The connecting portion 401 is cylindrical, and the second driving rod 5 has less resistance when sliding on the connecting portion 401, so as to avoid the cleaning member 3 from getting stuck when swinging.

[0037] Furthermore, the side wall of the unloading roller 2 has a unloading groove 201 , and there are multiple unloading grooves 201 , which are distributed at intervals around the circumference.

[0038] In this embodiment, a plurality of discharge troughs 201 are evenly distributed on the side wall of the discharge roller 2. During the rotation of the discharge roller 2, the powder first enters the discharge trough 201. As the discharge roller 2 rotates, the quantitative discharge of the powder is completed. By controlling the rotation speed of the discharge roller 2, the discharge speed can be adjusted, and the control is convenient.

[0039] Furthermore, the shell 1 has an inlet 101 and an outlet 102, and also includes a limit plate 7 and a fixed plate 8. There are two limit plates 7, and the two limit plates 7 are slidably set at the two ends of the inlet 101; one end of the fixed plate 8 is detachably set at the inlet 101, and the other end of the fixed plate 8 is set on the limit plate 7.

[0040] In this embodiment, the two ends of the feed port 101 are slidably provided with limit plates 7, and the limit plates 7 are connected to the feed port 101 through the fixed plates 8. The position of the limit plates 7 can be changed by changing the position of the fixed plates 8. The setting of the fixed plates 8 facilitates the connection between the limit plates 7 and the feed port 101. The position change of the two limit plates 7 can adjust the width of the feed port 101, and then adjust the discharge width of the discharge port 102. At the same time, the unloading rollers 2 of the discharge port 102 do not need to be adjusted, and the discharge width is easy to adjust, and the reliability is higher.

[0041] Furthermore, the shell 1 has a rotating chamber 103 , the feed port 101 , the rotating chamber 103 and the discharge port 102 are connected in sequence, the rotating chamber 103 is cylindrical, the unloading roller 2 is rotatably arranged in the rotating chamber 103 , and the side wall of the unloading roller 2 abuts against the rotating chamber 103 .

[0042] In this embodiment, the unloading roller 2 is arranged in the rotating chamber 103. During the rotation of the unloading roller 2, the side wall of the unloading roller 2 is always in contact with the rotating chamber 103. The powder is located between the unloading trough 201 and the rotating chamber 103. The shape of the rotating chamber 103 is cylindrical, and the powder is not easily adsorbed, reducing the difficulty of cleaning the shell 1.

[0043] Furthermore, the feed inlet 101 is V-shaped, and the small end of the feed inlet 101 is connected to the rotating chamber 103 .

[0044] In this embodiment, the shape of the feed inlet 101 is V-shaped. After the powder enters the feed inlet 101, it can naturally fall onto the discharge roller 2 under the action of gravity and complete the discharge as the discharge roller 2 rotates.

[0045] Furthermore, the feed chute 201 is V-shaped.

[0046] In this embodiment, the shape of the feed chute 201 is V-shaped, which is more convenient to process.

[0047] Furthermore, it also includes

[0048] The supporting legs 9 are multiple and the multiple supporting legs 9 are arranged on the surrounding side walls of the shell 1 .

[0049] In this embodiment, the support legs 9 are provided to facilitate supporting and fixing the housing 1 .

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
