The following describes specific embodiments to illustrate the implementation of the present invention, but it is not intended to limit the scope of the present invention.

Please refer to FIG. 1 and FIG. 5, which are a perspective view, a schematic side view of the structure, a schematic view of an operating state, a partial schematic view, and a partial perspective view. As shown in the figure, the dynamic powder supply device of the present invention includes a body 10 10 is provided with a feeding body 20 at one end and a discharging part 11 at the other end of the body. The feeding body 20 is in communication with the inside of the discharging part 11 and the powder is directly introduced into the body 10 through the feeding body 20, and On the top of the material body 20, there is a material body feeding portion 21, and on the bottom end of the material body 20, a material body discharging portion 22 is provided to introduce the powder through the material body feeding portion 21, and then The powder is led out by the feeding body discharging part 22, and a guide part 23 is further provided inside the feeding body 20, so that when the powder is introduced through the feeding body feeding part 21, the powder can be effectively guided by the feeding It is guided to the discharging part 22 of the feeding body. In addition, a vibrating body 24 is also provided on one side of the feeding body 20, and the vibrating body 24 can cause the feeding body 20 to vibrate. Because the powder itself is relatively light, When the feeding body 20 is relatively vibrated due to the vibration of the vibrating body 24, the powder can fall more effectively onto the feeding body discharge portion 22.

However, the feeding body discharging portion 22 is arranged adjacent to the peripheral edge of the rotating unit 30 so that the powder can effectively and accurately fall on the peripheral edge of the rotating unit 30. The rotating unit 30 is pivoted with the interior of the main body 10. Then, one end of the rotation unit 30 is connected to the first driving body 31 to drive the rotation unit 30 to rotate through the first driving body 31; and when the powder falls on the periphery of the rotation unit 30, The periphery of the rotation unit 30 is provided with a material clamping portion 32. Specifically, the material clamping portion 32 is a longitudinal groove perpendicular to the feeding body 20 and surrounds the periphery of the rotation unit 30. Therefore, when the powder falls on Rotating unit 30 When it is on the periphery, most of the powder will fall into the material holding portion 32.

When the rotating unit 30 rotates, it will first pass through 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. Therefore, when the powder passes through the pressing body, In the case of the body 40, the powder that partially falls on the periphery of the rotating unit 30 will be dispersed into the adjacent material holding portion 32 due to the pressure of the material body 40, and the powder contained in the material holding portion 32 Then, the powder inside the clamping portion is compacted by the pressing body 40. After that, it will pass through the auxiliary cutout unit 50. The auxiliary cutout unit 50 is connected to the body 10 and is disposed between the press body 40 and the guide body 60. One end of the auxiliary cutout unit 50 is provided with an auxiliary cutout. Part 51, the auxiliary removing part 51 is attached to the periphery of the rotating unit 30, so when the rotating unit 30 passes the position of the auxiliary removing unit 50, the rotating unit 30 can be passed through the auxiliary removing part 51 The remaining powder on the periphery is scraped off to avoid the powder sticking to the periphery of the rotating unit 30, and the scraped off powder will fall into the position of the discharge part 11 through the assistance of the guide body 60. The guide body 60 is connected to the main body 10. The guide body 60 is provided with a guide discharge portion 61 on one side, and the scraped powder is guided to the discharge portion 11 through the arc surface structure of the guide discharge portion 61. Position.

The cutout unit 70 is connected to the body 10 and is provided with a cutout portion 71 at one end. The cutout portion 71 is attached to the inside of the clamping portion 32, and the cutout portion 71 is attached to the recessed position of the longitudinal groove. Above, however, if the cutout section 71 is not fully bonded to the cutout section 32 and has a gap, although the amount of powder removal will be reduced in the cutout process, it can also achieve an approximation to the cutout section 71. efficacy. Therefore, when the rotation unit 30 is finally rotated to the position of the removing unit 70, the powder contained in the material-receiving portion 32 will be caused by the adhesion of the material-removing portion 71 and the material-receiving portion 32 or a gap between them. The powder is removed, and the powder is dropped on the position of the discharging portion 11 to effectively prevent the powder from sticking to the clamping portion 32. The discharge part 11 can be a completely open space or can be collected from the outlet (which can be a hole or a Narrow mouth)) and related structures.

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

In addition, in the state of dynamic powder feeding, its rotating unit 30 can adjust the rotation speed according to the type of powder, thereby improving the powder feeding stability. Furthermore, if there is a regular interval feeding demand or an irregular interval feeding demand, the second driving body 72 connected to the removal unit 70 can be used to drive the removal unit 70 to move forward and backward, so that There is a distance between the cutout portion 71 and the clipped portion 32, and the drive portion includes but is not limited to a slide rail, a gear, or a screw drive to drive the cutout unit 70 back and forth. In this way, when the interval feeding operation is performed, the removal unit 70 can be controlled to move back and forth regularly. For example, when the removal unit 70 uses 2 seconds as the standard for interval feeding, the removal unit 70 will be shifted back 1 second. After that, it is moved forward for 1 second to perform the powder removal operation, and the amount of powder to be removed can be adhered by the removal section 71 and the clamping section 32 (the removal section 71 and the clamping section can also be made). There is a space between the parts 32 to remove the powder. Here, the dwell time after the removal part 71 and the jamming part 32 are only used as an example) is determined as the same as when the user has completed After calculating the amount of powder that can be held by the depth and width of the clamping portion 32 and the amount of powder that can be removed by the rotation speed of the rotating unit 30, it can be clearly understood that if the removing portion 71 is attached to the clamping portion 32 After the combination, it stays for 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 in intervals. And if the feeding operation is performed at irregular intervals, different removal times of the removal unit 70 and the residence time after retreating to the final position can be set, as well as the time of forward movement and the forward position. The time to stay after moving to the position where the removing section 71 and the clamping section 32 are in contact with each other, and feeding is performed at irregular intervals.
