It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] The utility model embodiment provides a fully automatic toner metering feeder, such as Figure 1-3 As shown, it includes: a powder storage device 1, a powder supply device 2 and a metering device 3.

[0022] The powder storage device 1 includes a powder storage hopper 11, and the powder supply device 2 includes a powder supply hopper 21. A powder outlet pipe 22 is provided at the bottom of the powder supply hopper 21; the metering device 3 includes a shell 31, which is a shell with a hollow interior and openings at the top and bottom. The top of the shell 31 is connected to the bottom of the powder storage hopper 11, and the bottom of the shell 31 is connected to the top of the powder supply hopper 21. A metering wheel 32 is provided inside the shell 31. The side wall of the metering wheel 32 is evenly provided with a plurality of metering grooves 321 in a ring shape with its central axis as the center. The metering wheel 32 is connected to a driving mechanism 33 for driving the metering wheel 32 to rotate. The toner stored in the powder storage hopper 11 can enter the shell 31 through the driving mechanism 33 can drive the metering wheel 32 to rotate. When the metering groove 321 rotates to face upward, the toner inside the shell 31 flows into the metering groove 321. After the toner flows into the metering groove 321, the metering wheel 32 continues to rotate. When the metering groove 321 rotates to face downward, the toner inside the metering groove 321 flows out from the metering groove 321 and enters the powder supply hopper 21. When the toner is needed, the vacuum feeding pipe can be connected to the powder outlet pipe 22 to transport the toner inside the powder supply hopper 21 to a designated position. The toner can be automatically metered and transported to the designated position. This not only improves the work efficiency but also saves a lot of labor.

[0023] In this embodiment, a stirring blade 12 is provided inside the powder storage hopper 11. The stirring blade 12 is a mesh frame composed of a plurality of transverse stirring rods arranged transversely and a plurality of longitudinal stirring rods arranged longitudinally. The stirring blade 12 is connected to a first driving device 13 for driving the stirring blade 12 to rotate. The first driving device 13 can drive the stirring blade 12 to rotate, thereby stirring the toner inside the powder storage hopper 11 to avoid bridging of the toner inside the powder storage hopper 11. At the same time, the toner blocks inside the container body 11 can also be broken up to avoid affecting the metering device 2 to measure the toner.

[0024] In this embodiment, a feed hopper 14 is provided on the top side wall of the powder storage hopper 11, and toner can be added into the powder storage hopper 11 through the feed hopper 14. At the same time, a cover plate 15 is hinged on the top of the feed hopper 14 to prevent the toner inside the powder storage hopper 11 from overflowing through the feed hopper 14 and polluting the air.

[0025] In this embodiment, the first driving device 13 is a motor.

[0026] The first driving device 13 only needs to be able to drive the stirring blade 12 to rotate. Therefore, it is limited to the form of a motor. For example, in other embodiments, the first driving device 13 is a driving member such as a hydraulic motor or a pneumatic motor that can drive the stirring blade 12 to rotate.

[0027] In this embodiment, a control valve 23 is installed between the powder supply hopper 21 and the powder outlet pipe 22 . The control valve 23 can control the passage between the powder supply hopper 21 and the powder outlet pipe 22 , thereby controlling the output of toner inside the powder supply hopper 21 .

[0028] In this embodiment, the driving mechanism 33 includes a driven gear 331, which is connected to the metering wheel 33, and the driven gear 331 is meshed with the driving gear 332. The driving gear 332 is connected to a second driving device 333 for driving the driving gear 332 to rotate. The second driving device 333 can drive the driving gear 332 to rotate, and the driving gear 332 can drive the driven gear 331 to rotate, thereby driving the metering wheel 32 to rotate.

[0029] In this embodiment, the second driving device 333 is a motor.

[0030] The second driving device 333 only needs to be able to drive the active gear 332 to rotate. Therefore, it is limited to the form of a motor. For example, in other embodiments, the second driving device 333 is a driving member such as a hydraulic motor or a pneumatic motor that can drive the active gear 332 to rotate.

[0031] In this embodiment, an installation box 4 is also included, and the installation box 4 includes a box body 41. The powder storage device 1 and the feeding device 3 are installed on the top of the box body 41, and the powder supply device 2 is installed inside the box body 41. At the same time, rollers 42 are installed at the bottom of the box body 41 to facilitate the movement of the machine. The side wall of the box body 41 is hinged with a box door 43, which can open or close the box body 41, so that the color powder inside the powder supply device 2 can be easily observed.

[0032] Specific principle: When in use, the stirring blade 12 is driven to rotate by the first driving device 13 to stir the toner inside the powder storage hopper 11 to avoid the toner bridging phenomenon inside the powder storage hopper 11. At the same time, the toner blocks inside the container body 11 can be broken up to avoid affecting the metering device 2 to measure the toner. The toner stored in the powder storage hopper 11 can enter the shell 31. The metering wheel 32 can be driven to rotate by the driving mechanism 33. When the metering groove 321 rotates to face upward, the toner inside the shell 31 flows into the metering groove 321. After the toner flows into the metering groove 321, the metering wheel 32 continues to rotate. When the metering groove 321 rotates downward, the toner inside the metering groove 321 flows out from the metering groove 321 and enters the powder supply hopper 21. When the toner is needed, the vacuum feeding pipe can be connected to the powder outlet pipe 22 to transport the toner inside the powder supply hopper 21 to a designated position. The toner can be automatically metered and transported to the designated position. At the same time, the toner output can be controlled by the control valve 23, which not only improves the work efficiency but also saves a lot of labor.

[0033] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
