The top of the material body 20 is provided with a feed body inlet part 21, and the bottom body of the feed body 20 is provided with a feed body outlet part 22 to introduce the powder through the feed body inlet part 21, and then The powder is discharged by the feeder discharge part 22, and a guide part 23 is further provided inside the feeder 20, so that the powder can be effectively guided by the introduction when the powder is introduced through the feeder feeder 21 It leads to the discharge part 22 of the feed body. In addition, a vibration body 24 is also provided on one side of the feed body 20. The vibrator 24 can make the feed body 20 vibrate. When the feeding body 20 is relatively vibrated due to the vibration of the vibrating body 24, the powder can fall into the discharging part 22 of the feeding body more effectively.

However, the feeding body discharge part 22 is provided adjacent to the peripheral edge of the rotating unit 30 so that the powder can efficiently and accurately fall on the peripheral edge of the rotating unit 30, and the rotating unit 30 is pivoted with the inside of the body 10 One end of the rotating unit 30 is connected to the first driving body 31 to drive the rotating unit 30 to rotate through the first driving body 31; when the powder falls on the periphery of the rotating unit 30, A clamping portion 32 is provided on the periphery of the rotating unit 30, specifically, the clamping portion 32 is a longitudinal groove perpendicular to the feeding body 20 and surrounds the periphery of the rotating unit 30, so when the powder falls on When the rotating unit 30 is on the periphery, most of the powder will fall into the clamping portion 32.

When the rotating unit 30 rotates, it will first pass the position of the pressing body 40. The pressing body 40 is connected to the body 10 and fits with the periphery of the rotating unit 30, so when the powder passes through the pressing When the body 40, part of the powder falling on the periphery of the rotating unit 30 will be dispersed into the adjacent clamping portion 32 due to the pressing of the pressing body 40, and the powder contained in the clamping portion 32 It will be pressed by the pressing body 40 to compact the powder inside the clamping portion. After that, it will pass through the auxiliary removal unit 50, the auxiliary removal unit 50 is connected to the body 10 and is disposed between the pressing body 40 and the guide body 60, and the auxiliary removal unit 50 is provided with an auxiliary removal at one end The auxiliary cutout 51 is attached to the periphery of the rotary unit 30, so when the rotary unit 30 passes the position of the auxiliary cutout unit 50, the rotary unit 30 can be transferred through the auxiliary cutout 51 The remaining powder on the peripheral edge is scraped off to avoid the powder sticking to the peripheral edge of the rotary unit 30, and the scraped off powder will fall into the position of the discharge part 11 with the assistance of the guide body 60, The guide body 60 is connected to the main body 10, and the guide body 60 is provided with a guide discharge part 61 on one side, and guides the scraped powder to the discharge part 11 through the arc surface structure of the guide discharge part 61 Position.

The removal portion 71 is attached to the inside of the clamping portion 32, as is the removal portion 71 attached to the recessed position of the longitudinal groove However, if the cut-off part 71 is not completely attached to the clamping part 32 and has a gap, although the amount of powder removed will be reduced during the cut-out process, it can also achieve the similarity as the cut-out part 71 wants to achieve effect. Therefore, when the rotating unit 30 is rotated to the position of the removal unit 70, the powder contained in the clamping part 32 will be caused by the separation of the removal part 71 and the clamping part 32 or the gap between them. The powder is removed, and the powder is dropped on the position of the discharge part 11 to effectively prevent the powder from sticking to the card part 32. The discharge part 11 may be a completely open space or a related structure for collecting powder and leading it from an outlet (which may be a hole or a narrow mouth).

Therefore, through the above-mentioned actuation method, the amount of powder discharged can be adjusted according to the depth and width of the clamping portion 32 and the rotation speed of the rotating unit 30, as when the depth of the clamping portion 32 is deep or the width is wide The amount of powder that can be accommodated in the clamping portion 32 is relatively large, and if the rotation speed of the rotating unit 30 is increased, the amount of powder removed will also increase relatively because the operation process is accelerated.

In addition, in the state of dynamic powder feeding, the rotating unit 30 can adjust the rotation speed according to the type of powder, thereby improving the stability of powder feeding. Furthermore, if there is a regular interval feeding demand or an irregular interval feeding demand, the second driving body 72 connected to the removing unit 70 can be used to drive the removing unit 70 to move forward and backward, so that There is a gap between the cut-off part 71 and the clamping part 32, and they are attached to or separated from each other, and the driving methods thereof include, but are not limited to, slide rails, gears, or screw drives to drive the cut-off unit 70 to move forward and backward. In this way, when the interval feeding operation is performed, the cutting unit 70 can be controlled to move back and forth regularly. For example, when the cutting unit 70 uses 2 seconds as the interval feeding standard, the cutting unit 70 will move back and forth for 1 second. After that, it is moved forward again for 1 second to remove the powder, and the amount of powder to be removed can be matched by the removal part 71 and the clamping part 32 (it can also make the removal part 71 and the clamping part) There is a gap between the parts 32 for the powder rejection operation. Here, the residence time after the removal part 71 and the card part 32 are attached is used as an example to determine, also as when the user has completed The amount of powder that can be accommodated in the depth and width of the clamping part 32, and the amount of powder that can be rejected by the rotation speed of the rotating unit 30 can be clearly understood if the removal part 71 is stuck to the clamping part 32 After closing, for a period of 1 second, what is the amount of powder that can be removed, so that you can effectively grasp the required amount of powder, and you can also feed at intervals. If the feeding operation is performed at irregular intervals, the time for the different removal unit 70 to move backward and the dwell time after retreating to the last position, as well as the time to move forward and the forward displacement to the cutting unit 71 can be set. The time remaining after the position where it is in contact with the clamping part 32 is fed at irregular intervals.
