[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present invention are only for the convenience of narration and are not used to limit the scope of implementation of the present invention. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope of implementation of the present invention.

[0023] Refer to Figures 1-6 , a powder selecting machine with adjustable particle size, including a frame body 1, a first driving motor 2 is fixedly installed at the bottom inside the frame body 1, the top end of the output shaft of the first driving motor 2 is fixedly installed with a spring rod 3, the top end of the spring rod 3 is fixedly installed with a powder selecting cylinder 4, a plurality of powder selecting ports 5 are opened on the surface of the powder selecting cylinder 4, a plurality of baffles 6 are slidably arranged on the outer surface of the powder selecting cylinder 4 in a circumferential shape, the top ends of the plurality of baffles 6 are fixedly installed with an annular mounting plate 7, and the powder selecting cylinder 4 controls vertical high-frequency vibration through a pressing component;

[0024] A plurality of mounting openings are opened on the surface of the mounting plate 7 in a circumferential shape, a hollow rod 8 is vertically slidably arranged in the mounting opening, a suction cup 9 is fixedly installed at the bottom end of the hollow rod 8, the top ends of the plurality of hollow rods 8 are fixedly installed with an annular pressing plate 10, a telescopic spring 22 is sleeved on the hollow rod 8, and the two ends of the telescopic spring 22 are respectively fixedly connected with the pressing plate 10 and the mounting plate 7. A plurality of groups of desorption components are arranged on the upper surface of the pressing plate 10 in a circumferential shape, and the plurality of groups of desorption components are respectively used to release the adsorption of the plurality of suction cups 9. The desorption component includes a rotating shaft 14 and an arc plate 15 fixedly installed on the end surface of the rotating shaft 14 through a connecting rod. A plurality of through openings respectively communicated with the plurality of hollow rods 8 are opened on the upper surface of the pressing plate 10 in a circumferential shape, the plurality of rotating shafts 14 are respectively rotatably installed in the plurality of through openings in a sealed manner, an arc opening 16 is opened on the surface of the hollow rod 8, the arc plate 15 is used to cover the arc opening 16, the rotating shaft 14 is connected with the pressing plate 10 through an elastic component, the elastic component includes a torsion spring 17 sleeved on the rotating shaft 14, a mounting block is fixedly installed at the top end of the rotating shaft 14, and the two ends of the torsion spring 17 are respectively fixedly connected with the pressing plate 10 and the mounting block;

[0025] By rotating the mounting plate 7, multiple baffles 6 are controlled to rotate together, thereby changing the overlap degree between the multiple baffles 6 and the multiple powder selection ports 5. When the overlap degree between the baffle 6 and the powder selection port 5 gradually decreases, the diameter of the powder selection port 5 will increase at this time. When the overlap degree between the baffle 6 and the powder selection port 5 gradually increases, the diameter of the powder selection port 5 will decrease at this time. Thus, the adjustment of the sizes of the multiple powder selection ports 5 can be quickly completed, and the particle sizes that can be screened are no longer of a certain size, improving the practicability.

[0026] Then, when the multiple baffles 6 rotate to a suitable position, at this time, by controlling the pressing plate 10 to move downward, multiple hollow rods 8 and multiple suction cups 9 are controlled to move downward together, and multiple telescopic springs 22 will contract together until the suction cups 9 abut against the powder selection cylinder 4. At this time, since the arc-shaped opening 16 is covered by the arc-shaped plate 15, when the suction cup 9 deforms, the gas inside the suction cup 9 will escape from the gap between the contact surface of the suction cup 9 and the powder selection cylinder 4, and the suction cup 9 will be attracted to the powder selection cylinder 4, thereby achieving the effect of fixing the mounting plate 7 and the multiple baffles 6. When it is necessary to release the adsorption, as long as the rotating shaft 14 is rotated to control the arc-shaped plate 15 to rotate until it no longer covers the arc-shaped opening 16, at this time, the gas from the outside will enter the hollow rod 8 from the arc-shaped opening 16, thereby releasing the adsorption between the suction cup 9 and the powder selection cylinder 4. When the rotating shaft 14 is released, at this time, the rotating shaft 14 will drive the arc-shaped plate 15 to rotate and reset under the elastic potential energy of the torsion spring 17, and the arc-shaped plate 15 will cover the arc-shaped opening 16 again.

[0027] The pressing components include multiple support rods 11 fixedly installed on the inner bottom wall of the frame 1 in a circumferential shape, multiple abutting balls 12 respectively fixedly installed at the tops of the multiple support rods 11, and multiple hemispheres 13 fixedly installed on the lower surface of the powder selection cylinder 4 in a circumferential shape. Multiple abutting balls 12 are all located on the rotation paths of the multiple hemispheres 13.

[0028] The powder particles to be screened are put into the powder selection cylinder 4, and then the first driving motor 2 is started. The output shaft of the first driving motor 2 will drive the spring rod 3 and the powder selection cylinder 4 to rotate together. During the rotation process, multiple hemispheres 13 at the bottom of the powder selection cylinder 4 will respectively intermittently slide and contact with multiple abutting balls 12. When the hemisphere 13 abuts against the abutting ball 12, at this time, under the pressing action, the powder selection cylinder 4 will move upward. When the hemisphere 13 no longer abuts against the abutting ball 12, at this time, the powder selection cylinder 4 will quickly move downward and reset under the elastic potential energy of the spring rod 3. When the hemisphere 13 abuts against the abutting ball 12 next time, the powder selection cylinder 4 will quickly move upward again. Repeating like this can achieve the effect of controlling the vertical high-frequency vibration of the powder selection cylinder 4.

[0029] An aggregate box 18 is fixedly installed at the inner bottom of the frame 1, and the aggregate box 18 is used to collect the powder particles floating out from the powder selection port 5.

[0030] The top of the powder separator 4 is provided with a sliding opening, and a sliding rod 19 is slidably arranged in the sliding opening. A plurality of rotating rods 20 are fixedly installed on the end surface of the sliding rod 19 located inside the powder separator 4. A second driving motor 21 is fixedly installed on the inner top of the frame body 1, and the output shaft of the second driving motor 21 is fixedly connected to the sliding rod 19;

[0031] During the rotation and vertical high-frequency vibration of the powder separator 4, the second driving motor 21 can also be started to control the sliding rod 19 to drive the plurality of rotating rods 20 to rotate inside the powder separator 4, so as to achieve the effect of disturbing the powder particles located inside the powder separator 4, thereby accelerating the screening efficiency.

[0032] In the present utility model, by rotating the mounting plate 7 to control the plurality of baffles 6 to rotate together, the coincidence degree of the plurality of baffles 6 and the plurality of powder selection ports 5 can be changed. When the coincidence degree of the baffle 6 and the powder selection port 5 gradually decreases, the diameter of the powder selection port 5 will increase at this time, and when the coincidence degree of the baffle 6 and the powder selection port 5 gradually increases, the diameter of the powder selection port 5 will decrease at this time. Thus, the size adjustment of the plurality of powder selection ports 5 can be quickly completed, and the particle size that can be screened is no longer a certain size, improving the practicability.

[0033] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense.

[0034] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
