[0027] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0028] like Figure 1 , 2 As shown in 3, a powder spreading device capable of monitoring the amount of powder comprises a powder storage chamber 10, a powder outlet 11 is disposed at the lower end of the powder storage chamber 10, and a powder control component 20 is disposed on the powder outlet 11;

[0029] The powder control assembly 20 includes a powder controller 21 in a rotating body structure, and the rotating shaft of the powder controller 21 is transmission-connected to a driver 23;

[0030] The powder controller 21 includes a sealing surface 21a for closing the powder outlet 11 and a powder sprinkling groove 21b for accommodating powder, and the driver 23 drives the powder controller 21 to rotate so that the powder sprinkling groove 21b is alternately located inside or outside the powder storage chamber 10;

[0031] The powder storage chamber 10 is provided with a sensor 40 .

[0032] Furthermore, in order to improve the reliability, maintainability and service life of the sealed contact between the sealing surface 21a and the powder outlet 11, a powder baffle 22 is provided between the sealing surface 21a and the powder outlet 11, and the powder baffle 22 is made of elastic material.

[0033] Furthermore, the sensor 40 is a contact sensor or a non-contact sensor or a combination thereof.

[0034] The remaining amount of powder can be determined based on the distance between the powder and the sensor, the color difference between the powder and the powder storage chamber or the powder controller, the change of electromagnetic waves or the sonar echo. A distance sensor, a color sensor, an electromagnetic sensor or a sonar sensor can be selected. Depending on the sensor type, the sensor can be arranged inside or outside the powder storage chamber 10.

[0035] The sensor can be a distance sensor, which determines the remaining powder amount by the height of the powder accumulation (the distance can be set). It can also be a color sensor, which detects the difference in color between the powder storage chamber or the powder controller and other objects when the powder is exhausted to determine the remaining powder amount; it can also be a sonar sensor, which determines the remaining powder amount by the sonar echo of the internal space of the powder storage chamber.

[0036] Furthermore, the sensor 40 is a laser or infrared sensor disposed above the powder outlet 11 .

[0037] According to the powder type and working conditions, this embodiment uses laser and infrared non-contact photoelectric sensors. In other embodiments, other types of sensors, such as contact sensors, may also be used.

[0038] Furthermore, in order to reduce the residual powder, the powder storage chamber 10 is a thin-walled funnel-shaped structure that is larger at the top and smaller at the bottom.

[0039] Furthermore, in order to facilitate powder discharge, the powder outlet 11 is located at the bottom of the powder storage chamber 10 in the gravity direction.

[0040] Furthermore, in order to facilitate powder adding and cleaning of the powder storage chamber, a powder adding port and a cover 30 covering the powder adding port are provided at the upper end of the powder storage chamber 10 .

[0041] Furthermore, in order to facilitate manual judgment of the powder residue, the cover 30 is provided with an observation window 31 made of a transparent material.

[0042] Furthermore, in order to facilitate processing and control the amount of powder output, the powder outlet 11 is a rectangular structure, the powder controller 21 is a cylindrical structure, the sealing surface 21a is an arc surface, and the powder sprinkling groove 21b is a groove-shaped structure recessed in the surface of the sealing surface 21a.

[0043] The volume of the powder sprinkling trough 21b can be designed according to factors such as powder characteristics and powder sprinkling speed, so as to achieve controllable powder sprinkling accuracy and speed.

[0044] In other embodiments, powder outlets and powder controllers of different shapes are designed according to powder properties and powder spreading speed.

[0045] Furthermore, the driver 23 is a rotary motor.

[0046] When the present embodiment is in use, firstly, an appropriate amount of powder is placed into the powder storage chamber 10. When sprinkling powder, the controller controls the driver 23 to drive the powder controller 21 to rotate; when the powder sprinkling groove 21b rotates to the inside of the powder storage chamber 10 (at this time, the sealing surface 21a closes the powder outlet 11), the powder is filled into the powder sprinkling groove 21b under the action of gravity; when the powder sprinkling groove 21b rotates to the outside of the powder outlet 11 and the powder storage chamber 10, the powder in the powder sprinkling groove 21b falls, thereby circulating and rotating to achieve continuous powder sprinkling.

[0047] When the powder sprinkling stops, the sealing surface 21 a closes the powder outlet 11 .

[0048] When the sensor detects that the powder remaining is insufficient, it sends a message to prompt the operator to add powder.

[0049] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of the utility model patent.
