[0027] The flow guide mechanism includes a top cover 201, the top cover 201 is threadedly connected to the top of the tank body 1, the top cover 201 is fixedly connected with a pressurizing pipe 202, the top of the pressurizing pipe 202 is fixedly connected with a gas conveying pipe 203, the operator can connect the gas conveying pipe 203 with an external gas supply device, then open the top cover 201 to add powder into the tank body 1, and then tighten the top cover 201 to complete sealing.

[0028] The fixing mechanism includes a plurality of through holes 302, the through holes 302 are formed in the outer surface of the fixing frame 301, the fixing frame 301 is fixedly connected with a conical block 303, the gas passes through the gas conveying pipe 203 and is input into the pressurizing pipe 202, then passes through the plurality of through holes 302 into the tank body 1, the powder in the tank body 1 is sprayed downward through the bottom of the tank body 1 for powder scattering, and the conical block 303 can make the recovered powder fall smoothly to avoid accumulation.

[0029] The stirring mechanism includes a plurality of stirring rods 403, the stirring rods 403 are fixedly connected to the outer surface of the rotating shaft 402, the motor 401 is started, the motor 401 drives the rotating shaft 402 to rotate, the rotating shaft 402 drives the plurality of stirring rods 403 to rotate, and the powder in the tank body 1 is stirred to avoid caking.

[0030] The collection mechanism includes two extension tubes 601, which are fixedly connected to both sides of the pressure tube 202. A collection cover 602 is fixedly connected to the bottom of the extension tubes 601. Excess powder sprayed on the paper is drawn upward through the two extension tubes 601 and the collection cover 602.

[0031] The intermittent mechanism includes two support rings 701, which are fixedly connected to the inner wall of the extension tube 601. A cover plate 703 overlaps the top of the support rings 701. A protruding plate 702 is fixedly connected to the inner surface of the extension tube 601. The protruding plate 702 is hinged to the cover plate 703. A coil spring is built into the hinge. When gas flows through the extension tube 601, the cover plate 703 will be lifted upward under the action of negative pressure to ensure the upward recovery of powder. When the device stops running, the cover plate 703 will be reset under the action of the coil spring and contact the support rings 701 again to close the extension tube 601 and prevent the powder from falling during the upward process, thus affecting the powder spreading effect.

[0032] Working principle: When using this device, the operator first connects the gas supply pipe 203 to the external gas supply equipment, then opens the top cover 201 to add the powder into the tank 1, and then tightens the top cover 201 to complete the seal.

[0033] The motor 401 is started, which drives the rotating shaft 402 to rotate. The rotation of the rotating shaft 402 drives several stirring rods 403 to rotate, stirring the powder in the tank 1 to prevent clumping. At the same time, the rotating shaft 402 also drives the conical cover 503 to rotate. The rotation of the conical cover 503 drives several impact blocks 504 to rotate. The rotation of the impact blocks 504 continuously impacts the protrusions 506, thereby generating vibration. The vibration is transmitted to the filter screen 502 through the fixed column 505, thereby preventing the powder from clogging the surface of the filter screen 502 and ensuring the normal operation of the device.

[0034] The gas passes through the gas delivery pipe 203 and is input into the pressurization pipe 202. Then it enters the tank 1 through several through holes 302, and the powder in the tank 1 is sprayed downward through the bottom of the tank 1 for powdering.

[0035] When the gas passes through the gas delivery pipe 203 and is input into the pressurization pipe 202, the gas flow rate increases because the inner diameter of the pressurization pipe 202 is smaller than that of the gas delivery pipe 203. At this time, the gas in the pressurization pipe 202 will generate negative pressure, and the excess powder sprayed on the paper will be drawn upward through the two extension pipes 601 and the collection hood 602, and then flowed back into the tank 1 through the pressurization pipe 202, so that it can re-enter the powder spreading process, saving costs and avoiding waste of raw materials.

[0036] As the gas flows through the extension tube 601, the cover plate 703 will lift upward under the action of negative pressure to ensure the upward recovery of the powder. When the device stops running, the cover plate 703 will return to its original position under the action of the coil spring and contact the support ring 701 to close the extension tube 601 again, so as to prevent the powder from falling during the upward process and thus affecting the powder spreading effect.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
