[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Example 1

[0031] refer to Figures 1 to 6 , an electric device for screening target powder, comprising a frame 1, a screening mechanism 2, the screening mechanism 2 is connected to the frame through an elastic component 11, and also comprises a limit block 3 and a rotating shaft 4, the limit block 3 is arranged at the bottom of the screening mechanism 2, the limit block 3 is provided with a vertically arranged first slide groove 31, the frame 1 is provided with a rotating mechanism 12, one end of the rotating shaft 4 is eccentrically connected to the rotating mechanism 12, and the other end of the rotating shaft 4 is located in the first slide groove 31;

[0032] The rotating mechanism 12 is used to drive the rotating shaft 4 to rotate so that the screening mechanism 2 swings;

[0033] When the rotating shaft 4 is located at the bottom end of the first sliding slot 31 , the compression amount of the elastic component 11 is maximum.

[0034] Under this design, the rotating shaft 4 is located at the top of the first chute 31 in the initial state. When the target powder needs to be screened, the material is first fed into the screening mechanism 2, and then the rotating mechanism 12 is started. Since the rotating shaft 4 is eccentrically connected to the rotating mechanism 12, and one end of the rotating shaft 4 is located in the first chute 31 provided on the limiting plate 5, when the rotating mechanism 12 drives the rotating shaft 4 to rotate, each rotation of the rotating shaft 4 will pass through the top and bottom of the first chute 31, so that the screening mechanism 2 forms a circular trajectory motion, and cooperates with the elastic component 11 to make the screening mechanism 2 vibrate. After the rotating mechanism 12 drives the rotating shaft 4 to rotate multiple times, the screening of the target powder is completed. In this way, the screening mechanism 2 can move left and right and up and down, so that the target powder pressed at the bottom can be lifted up, so as to better screen out large particles of target powder. The structure is simple and easy to maintain, and the effect and efficiency of powder screening are improved.

[0035] Preferably, the rotating mechanism 12 includes a rotating motor 121 disposed on the frame 1 , an eccentric wheel 122 disposed at an output end of the rotating motor 121 , and the rotating shaft 4 is eccentrically connected to the eccentric wheel 122 .

[0036] Specifically, by eccentrically connecting the rotating shaft 4 to the eccentric wheel 122, when the rotating motor 121 is running, since one end of the rotating shaft 4 is located in the first slide groove 31, the rotation of the rotating shaft 4 will drive the swing of the screening mechanism 2 and cooperate with the elastic component 11 to complete the screening of the target powder.

[0037] In this embodiment, a screw 1221 is passed through the bottom end of the eccentric wheel 122 , and a sensor 13 for sensing the position of the screw 1221 is also provided on the frame 1 .

[0038] Furthermore, when the device stops operating, the position of the screw 1221 is sensed by using the sensor 13, so that each time the device stops, the connecting shaft can be located at the top of the first slide groove 31, so that each time the device starts, the rotating shaft 4 can operate in the initial state.

[0039] In this embodiment, a bearing 6 matching the first sliding groove 31 is sleeved on the rotating shaft 4 . The bearing 6 is located in the first sliding groove 31 and slidably matches with the first sliding groove 31 .

[0040] Specifically, the bearing 6 is slidably matched with the first slide groove 31 to reduce friction, so that when the rotating shaft 4 rotates, the screening mechanism 2 can be better driven to swing, thereby completing the screening of the target powder, and the bearing 6 can reduce noise and extend the life of the equipment.

[0041] In this embodiment, a clamping portion 41 is provided on the rotating shaft 4, and also includes a limiting plate 5 which is detachably connected to the limiting block 3. The limiting plate 5 is located on the side of the limiting block 3 away from the clamping portion 41. One side of the bearing 6 abuts against the clamping portion 41, and the other side abuts against the limiting plate 5. The limiting plate 5 is used to cooperate with the clamping portion 41 to limit the lateral displacement of the bearing 6.

[0042] Furthermore, in order to prevent the bearing 6 from disengaging from the first slide groove 31 during the operation of the equipment, it is necessary to limit the lateral displacement of the bearing 6. One side of the bearing 6 is tightened by the tightening portion 41, and the other side is limited by the limiting plate 5. In this way, the bearing 6 can be limited in the first slide groove 31 to prevent its lateral displacement and thus fall out of the first slide groove 31. Moreover, the limiting plate 5 is detachably connected to the limiting block 3. In this way, when the bearing 6 needs to be replaced, only the limiting plate 5 needs to be removed, which is convenient and quick.

[0043] In practical applications, the limiting plate 5 is provided with a vertically arranged second slide groove 51 , the second slide groove 51 matches the shaft diameter of the rotating shaft 4 , and one end of the rotating shaft 4 passes through the first slide groove 31 and the second slide groove 51 .

[0044] Specifically, during the equipment assembly process, there will be certain assembly errors. When the errors gradually accumulate, the rotating shaft 4 will press against the limit plate 5, making it impossible for the limit plate 5 to be installed on the limit block 3. Therefore, a second slide groove 51 matching the axial diameter of the rotating shaft 4 is provided on the limit block 3. This can avoid the problem of the rotating shaft 4 being too long to interfere with the installation of the limit block 3, and will not interfere with the limiting of the bearing 6.

[0045] Preferably, the first chute 31 and the second chute 51 are both waist-shaped structures. The waist-shaped first chute 31 and the second chute 51 can guide the rotation shaft 4 to rotate, so that the screening mechanism 2 completes a circular motion trajectory.

[0046] Preferably, the screening mechanism 2 includes a funnel 21, a screening frame 22, a screen 23, and a fixing frame 24, the fixing frame 24 is arranged on the elastic component 11, the screening frame 22 is arranged on the fixing frame 24, the screen 23 is arranged obliquely in the screening frame 22, and the funnel 21 is arranged on the screening frame 22; it also includes a first collecting bucket 25 and a second collecting bucket 26, a first discharge port 221 is provided on one side of the screening frame 22, a second discharge port 222 is provided at the bottom of the screening frame 22, and the second discharge port 222 is located below the screen 23, the first discharge port 221 is connected to the first collecting bucket 25 through a first pipe 27, and the second discharge port 222 is connected to the second collecting bucket 26 through a second pipe 28.

[0047] Specifically, workers can put target powder into the funnel 21, so that the target powder will first fall onto the screen 23. As the rotating mechanism 12 drives the rotating shaft 4 to rotate, it will drive the vibration of the fixed frame 24 and the screening frame 22. In this way, large target powder will first pass through the first discharge port 221 along the inclined direction, and then pass through the first pipe 27 and fall into the first collecting bucket 25, while the fine target powder will pass through the screen 23 and fall from the second pipe 28 to the second collecting bucket 26 after passing through the second discharge port 222.

[0048] Preferably, the elastic component 11 includes a first support seat 111, a second support seat 112, and a spring 113. The first support seat 111 is arranged on the frame 1, the second support seat 112 is arranged at the bottom of the screening mechanism 2, and the spring 113 is arranged between the first support seat 111 and the second support seat 112.

[0049] The two ends of the spring 113 are fixed by using the first support seat 111 and the second support seat 112, and the first support seat 111 is set on the frame 1, and the second support seat 112 is set at the bottom of the screening mechanism 2. In this way, when the rotating shaft 4 rotates, the spring 113 can cooperate with the screening mechanism 2 to vibrate.

[0050] The above are only preferred implementations of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or modifications can be made without departing from the principle of the present invention. These improvements or modifications should also be regarded as the protection scope of the present invention.
