[0042] In order to enable anyone skilled in the relevant art to understand the technical content of the utility model and implement it accordingly, and according to the contents disclosed in this specification, the scope of the patent application and the drawings, anyone skilled in the relevant art can easily understand the relevant purposes and advantages of the utility model. Therefore, the detailed features and advantages of the utility model will be described in detail in the embodiment method.

[0043] like Figure 1 As shown, this embodiment is a powder circulation system 100 , which includes: a sonic feeder 10 ; a sonic powder sifter 20 ; and a new and old material mixing tank 30 .

[0044] like Figure 2 As shown, the ultrasonic feeder 10 has a first material storage tank 110. The first material storage tank 110 is mainly used to store new spraying materials to be sprayed. In order to smoothly feed the materials, the first material storage tank 110 has a new spraying material outlet 111.

[0045] In order to effectively control the stock level of the first material storage tank 110 , the sonic feeder 10 may include a photoelectric sensor 120 for detecting the stock level of the new spray material in the first material storage tank 110 so as to maintain an appropriate stock level.

[0046] In order to accurately control the feeding amount of the sonic feeder 10 to the new and old material mixing tank 30, a solenoid valve 130 can be provided at the new material spraying outlet 111, and the opening or closing of the solenoid valve 130 can be controlled by a timer 140, thereby effectively controlling the feeding amount of the first material storage tank 110 to the new and old material mixing tank 30. However, it is not limited to this, and other non-solenoid valve devices can also be used to achieve the same effect of effectively controlling the feeding amount.

[0047] In addition to using the solenoid valve 130 to control the feeding amount, an electronic flow controller 150 can also be provided at the new material outlet 111, thereby accurately controlling the feeding amount of the sonic feeder 10 to the new and old material mixing tank 30. The solenoid valve 130 and the electronic flow controller 150 can be used separately or together.

[0048] like Figure 3 As shown, the sonic powder sifting machine 20 comprises: a material receiving trough 210; and a material sifting trough 220.

[0049] The material collecting trough 210 is mainly used to collect the remaining materials after the fastener 62 is sprayed, so the material collecting trough 210 has a recycling material inlet 211 and an exhaust hole 212; the recycling material inlet 211 is used to collect the remaining materials, and the exhaust hole 212 is mainly used to allow the gas transporting the remaining materials to be smoothly discharged from the material collecting trough 210, so that the pneumatic flow of the remaining materials collected by the material collecting trough 210 can remain smooth.

[0050] The screening trough 220 is connected to the material receiving trough 210 and has a regenerated spray material outlet 221 and a waste material outlet 222. That is to say, the screening trough 220 is used to receive the residual materials collected by the material receiving trough 210, and then perform the first step of screening, and screen out the regenerated spray material that can be reused and output it from the regenerated spray material outlet 221, and screen out the waste of poor quality and discharge it from the waste material outlet 222.

[0051] like Figure 4As shown, the new and old material mixing tank 30 includes: a first feed pipe 310; a second feed pipe 320; a blow hole 330; and a mixing tank outlet 340.

[0052] The first feed pipe 310 is connected to the new material outlet 111, so the new and old material mixing tank 30 can obtain the supply of new material, and the second feed pipe 320 is connected to the regenerated material outlet 221, so the new and old material mixing tank 30 can also obtain the supply of regenerated material.

[0053] In order to fully and evenly mix the new spray material with the recycled spray material, the new and old material mixing tank 30 can be designed as a conical structure. In addition, a flow equalizing plate 350 can be further designed below the blowing hole 330 in the new and old material mixing tank 30.

[0054] The flow equalizing plate 350 has a plurality of evenly distributed flow equalizing openings 351. The flow equalizing openings 351 enable the gas input from the blowing hole 330 to be evenly blown in the new and old material mixing tank 30. A vortex element 360 may be further provided below the flow equalizing plate 350 so that the gas passing through the flow equalizing plate 350 can generate a gas vortex stirring effect again. However, the present invention is not limited to this and other designs that can achieve uniform vortexes may also be used.

[0055] The first feed pipe 310 and the second feed pipe 320 are connected and designed to be located on both sides of the new and old material mixing tank 20, and are located at a height between the flow equalizing plate 350 and the vortex element 360. In addition, the first feed pipe 310 and the second feed pipe 320 can also be arranged parallel to each other, so that the new spray material and the regenerated spray material can flow along the gas in the vortex, and then be completely and fully evenly mixed.

[0056] The blowing hole 330 is connected to the new and old material mixing tank 30 and corresponds to the upper side of the first feed pipe 310 and the second feed pipe 320. The gas introduced into the new and old material mixing tank 30 through the blowing hole 330 can fully and evenly mix the new spray material and the regenerated spray material under the action of the first feed pipe 310, the second feed pipe 320, the flow equalizing plate 350 and the vortex element 360.

[0057] The mixing tank discharge port 340 is arranged at the lower side of the new and old material mixing tank 30. When the new spraying material and the recycled spraying material fully and evenly produce the new and old mixed materials in the new and old material mixing tank 30, the mixing tank discharge port 340 will be used to output the produced new and old mixed spraying materials.

[0058] like Figure 5 As shown, in order to effectively complete the spraying operation, the powder circulation system 100 may further have a second material storage tank 40, and the second material storage tank 40 is used to receive and store the new and old mixed spray materials from the mixing tank outlet 340.

[0059] The powder circulation system 100 may further include a nozzle 51 and a suction nozzle 52 for spraying the fasteners 62 on the continuous conveyor belt 61, wherein the nozzle 51 is connected to the output end of the second material storage tank 40, and the suction nozzle 52 is connected to the recycling material inlet 211, so that the remaining material after the nozzle 51 sprays the fasteners 62 will be effectively recovered by the suction nozzle 52, and then regenerated spray material will be produced.

[0060] However, the above embodiments are used to illustrate the features of the present invention, and their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly, rather than to limit the patent scope of the present invention. Therefore, any other equivalent modifications or modifications that do not deviate from the spirit disclosed by the present invention should still be included in the scope of the patent application described above.
