DETAILED DESCRIPTION

[0036] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of 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.

[0037] Example

[0038] The utility model will be further described below in conjunction with the accompanying drawings.

[0039] like Figure 1 , 2 As shown, the material collecting and discharging device for the powder classifier provided in this embodiment includes: a hopper 1, a material pipe 2, a material plate 3 and a baffle 6, wherein the hopper 1 is connected to the discharge port of the powder classifier; the material pipe 2 is obliquely connected to the bottom end of the hopper 1; the material plate 3 is connected to the inner wall of the material pipe 2, and divides the material pipe 2 into an upper tube cavity 4 and a lower tube cavity 5, and a driving unit for driving the material plate 3 to deform along the length direction is connected to the lower tube cavity 5; the baffle 6 is connected to the outlet end of the material pipe 2, and the baffle 6 blocks the lower tube cavity 5.

[0040] The material plate 3 is configured as a flexible plate, the material plate 3 is configured as any one of a cloth plate and a film plate, and the edge of the material plate 3 is connected with a frame.

[0041] The outlet end of the material pipe 2 is lower than the end where the material pipe 2 is connected to the hopper 1 .

[0042] The working principle and beneficial effects of the utility model are as follows:

[0043] When in use, the hopper 1 collects the separated powder, and the material tube 2 tilts downward from the end connected to the hopper 1, so that the powder can be discharged downward along the material plate 3. Since the material plate 3 is set to be flexible, that is, the material plate 3 can produce a certain amount of deformation along the length direction; when the powder adheres to the material plate 3 and is retained, the drive unit is started to make the material plate 3 intermittently deform along the length direction, so that the powder is separated from the material plate 3 and slides off, reducing adhesion. A frame is set at the edge of the material plate 3, and is connected to the inner wall of the material tube 2 through the frame, which is convenient for the replacement of the material plate 3 and can better maintain the shape of the material plate 3. The lower tube cavity 5 is blocked by the baffle 6, which can effectively prevent the powder from flowing back into the lower tube cavity 5 and keep the lower tube cavity 5 and the drive unit clean.

[0044] The material collecting and discharging device for the powder selecting machine provided in the present embodiment blocks the lower tube cavity 5 by the baffle plate 6, so as to reduce the reflux of powder and keep the lower tube cavity 5 clean. The powder adhering to the material plate 3 is loosened by the intermittent deformation and resetting along the length direction, so as to avoid the retention and blockage of powder. Compared with the method of driving the material plate 3 to shake in the vertical direction, the powder can be prevented from being shaken and bounced to the top of the material pipe 2, thereby reducing the dust of powder and the adhesion of powder on the top of the material pipe 2, thereby improving the powder output rate of the material collecting and discharging device and achieving better use effect.

[0045] like Figure 3-5 As shown, in one embodiment, two first shifting blocks 7 are spaced apart and connected to the bottom end of the material plate 3 .

[0046] The driving unit comprises:

[0047] A guide groove 8, which is provided on the side wall of the lower tube cavity 5 and is arranged parallel to the material plate 3;

[0048] A driving plate 9, wherein the driving plate 9 is slidably connected in the guide groove 8;

[0049] A second shift block 10, wherein two of the second shift blocks 10 are connected to the top of the driving plate 9 at intervals, and the two second shift blocks 10 are respectively abutted against opposite sides of the two first shift blocks 7;

[0050] A turntable 11, wherein the turntable 11 is rotatably connected to the inner wall of the lower tube cavity 5, and the rotation axis of the turntable 11 extends to connect the discharge pipe 2 to the input end of the motor;

[0051] A sliding post 12, wherein the sliding post 12 is eccentrically connected to the rotating disk 11;

[0052] The slide rod 13 is connected to the center of the bottom end of the driving plate 9 . The slide rod 13 is provided with a slide groove 14 along the length direction. The slide column 12 is slidably connected in the slide groove 14 .

[0053] The center line of the driving plate 9 is collinear with the center line of the turntable 11 .

[0054] The working principle and beneficial effects of the above technical solution are:

[0055] When the driving unit is used, the motor is started to drive the turntable 11 to rotate, and the slide post 12 on the turntable 11 rotates accordingly. When the slide post 12 rotates, it slides along the slide slot 14 at the same time. When the slide post 12 gradually moves away from the center of the turntable 11, the slide bar 13 moves away from the center of the turntable 11, driving the driving plate 9 to move to one side. When the driving plate 9 moves, it drives the second shift block 10 to move. One of the second shift blocks 10 squeezes the first shift block 7, and the first shift block 7 pulls the material plate 3 to deform along the length direction. When it is pulled to a certain length, the elastic force on the material plate 3 is large, which drives the first shift block 7 to deflect and separate from the second shift block 10, so that the material plate 3 is quickly reset. As the turntable 11 rotates, it drives the driving plate 9 to move in the opposite direction. At this time, after the second shift block 10 contacts the first shift block 7 again, the material plate 3 is pulled to deform in the opposite direction. After reaching the limit position, the first shift block 7 deflects again and separates from the second shift block 10, so that the material plate 3 is quickly reset. When the driving plate 9 moves to the second shift block 10 on the other side and contacts the first shift block 7, the above action is repeated. Therefore, under the drive of the driving unit, the material sheet 3 is intermittently deformed along the length direction, and the material sheet 3 is frequently stretched and quickly reset, which produces an acceleration difference with the powder on the material sheet 3, causing the powder to shift relative to the material sheet 3, loosening the powder while preventing the powder from being ejected to generate dust or adhering to the top of the material tube 2.

[0056] like Figure 3 , 6 As shown, in one embodiment, the driving unit further includes a knocking component, and the knocking component includes:

[0057] An incomplete gear 15, wherein two of the incomplete gears 15 are rotatably connected to the inner wall of the lower tube cavity 5, and the two incomplete gears 15 are symmetrically arranged on both sides of the rotating disk 11, and a latching tooth is arranged on one side of the incomplete gear 15 close to the driving plate 9;

[0058] A rack 16, the rack 16 is connected to the bottom end of the driving plate 9, and the rack 16 is meshed with the incomplete gear 15;

[0059] A sleeve 17, wherein the sleeve 17 is connected to a side of the incomplete gear 15 away from the driving plate 9, and the bottom end of the sleeve 17 is open;

[0060] A knocking rod 18 is slidably connected inside the knocking rod 18, a spring 19 is connected between the top end of the knocking rod 18 and the sleeve 17, a knocking head is connected to the bottom end of the knocking rod 18, and when the spring 19 is in an uncompressed state, the total length of the sleeve 17 and the knocking rod 18 is greater than the distance from the incomplete gear 15 to the material pipe 2.

[0061] The working principle and beneficial effects of the above technical solution are:

[0062] When the driving plate 9 moves, the rack 16 meshes with the incomplete gear 15 to drive the incomplete gear 15 to rotate, and the sleeve 17 rotates accordingly, that is, as the driving plate 9 moves, the knocking rod 18 reciprocates. When the driving plate 9 moves to the extreme position on one side, the knocking rod 18 tilts, and under the action of the spring 19, it remains in the ejected state and separates from the material tube 2; as the driving plate 9 moves in the reverse direction, the incomplete gear 15 rotates in the reverse direction, driving the knocking rod 18 to knock the material tube 2, so that a vibration wave is generated on the tube wall of the material tube 2, and the powder attached to the top of the material tube 2 is shaken off, and then the material tube 2 squeezes the knocking rod 18 into the sleeve 17 and compresses the spring 19, which will not hinder the rotation of the incomplete gear 15 until it rotates to the extreme position on the other side and moves in the reverse direction again. Through the above structural design, while shaking off the powder, the material tube 2 is knocked, the amount of powder attached to the top of the inner wall of the material tube 2 is reduced, and blockage at the top of the material tube 2 is avoided, thereby improving the discharge rate of the device.

[0064] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
