DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] As attached Figure 1-6 The ultrafine powder coating mixer shown in the figure includes a mixing box 1, and a plurality of supporting legs 2 are arranged on the outer wall of the mixing box 1 for supporting the mixing box 1, a discharge pipe 3 is connected to the bottom of the mixing box 1, and a feeding cylinder 4 is arranged at the bottom of the discharge pipe 3 for conveying the mixed powder coating to the inside of the feeding cylinder 4 through the discharge pipe 3, and a discharge pipe 5 is arranged at the bottom of one end of the feeding cylinder 4 for discharging the mixed powder coating through the feeding cylinder 4, and a feeding port 6 is arranged at the top of the mixing box 1 for adding powder coating to be mixed into the mixing box 1, a first motor 7 is arranged at the rear side of the mixing box 1, a rotating rod 8 is arranged at the output end of the first motor 7, and a plurality of stirring rods 9 are distributed in an annular shape on the outer wall of the rotating rod 8, and a material shovel 10 is fixedly installed at one end of each stirring rod 9, and the output end of the first motor 7 is coaxially connected with the rotating rod 8, and the rotating rod 8, the stirring rod 9 and the material shovel 10 are all located inside the mixing box 1 for mixing and stirring the powder material inside the mixing box 1.

[0024] Combined with Figure 1 , 2 As shown in , 3 and 4, a dust handling structure is provided on the top of the feeding port 6, and the dust handling structure includes a dust cover 11, which is installed on the top of the feeding port 6, and two slide grooves 19 are provided on the surface of the feeding port 6, and two sliders 20 are provided at the bottom of the dust cover 11, and the sliders 20 are slidably connected inside the slide grooves 19, and a filter screen 21 is installed on the lower surface of the dust cover 11 by screws, and a processing box 12 is provided on the front surface of the mixing box 1, and a collection box 13 is slidably provided inside the processing box 12, and a collection box 13 is collected. A sealing plate 25 is provided on the surface of the box 13, and a groove 26 is opened on the surface of the sealing plate 25. A plurality of threaded holes are provided at the connection between the sealing plate 25 and the processing box 12, and bolts 27 are threadedly installed inside the plurality of threaded holes. A dust suction pump 14 is provided on the top of the processing box 12, and a dust conveying hose 15 is provided at the input end of the dust suction pump 14. The input end of the dust suction pump 14 is connected to the dust conveying hose 15, and one end of the dust conveying hose 15 is connected to the dust removal cover, and the output end of the dust suction pump 14 extends to the interior of the processing box 12.

[0025] Specifically, in this structure, when powder coating needs to be added to the mixing box 1 through the feeding port 6, the dust cover 11 can be pushed so that the two sliders 20 at the bottom of the dust cover 11 slide inside the slide groove 19 at the feeding port 6. At this time, the feeding port 6 is in an open state, and powder coating can be added through the feeding port 6.

[0026] After the addition is completed, the dust cover 11 is closed in the same way. The setting of the dust cover 11 can reduce the dust generated during the mixing process of the powder coating from being blown out through the feeding port 6. In the process of generating dust, the dust can be transported to the inside of the treatment box 12 through the dust conveying hose 15 by the dust suction pump 14, and fall into the inside of the collecting box 13. The operator can loosen the bolts 27 to pull the collecting box 13 out of the inside of the treatment box 12 to deal with the collected dust. A filter screen 21 is installed on the bottom of the dust cover 11 by screws. The filter holes of the filter screen 21 are smaller than the powder coating particles, which ensures that the powder coating will not be sucked out along with the dust during the vacuuming process, thereby removing the dust from the powder coating and improving the later use effect of the powder coating.

[0027] Furthermore, a mounting tube 16 is provided on the surface of the processing box 12, a plurality of atomizing nozzles 17 are provided on the back of the mounting tube 16, a connecting tube 18 is provided on the surface of the mounting tube 16, the connecting tube 18 is connected to the mounting tube 16, the plurality of atomizing nozzles 17 are all connected to the mounting tube 16, and the plurality of atomizing nozzles 17 extend to the interior of the processing box 12.

[0028] In order to further reduce the phenomenon of secondary dust when processing the dust inside the collection box, after the collected dust enters the processing box 12, one end of the connecting pipe 18 is connected to the water source, so that the water enters the interior of the mounting pipe 16 through the connecting pipe 18, and finally is sprayed into the interior of the processing box 12 through the atomizing nozzle 17, so as to perform dust reduction treatment on the collected dust and reduce the environmental impact caused by secondary dust.

[0029] In a specific embodiment, as shown in the attached Figure 1 , 6 As shown, a second motor 22 is provided at one end of the feeding cylinder 4, a conveying rod 23 is provided inside the feeding cylinder 4 at the output end of the second motor 22, a plurality of conveying dragons 24 are provided on the surface of the conveying rod 23, and the output end of the second motor 22 is coaxially connected with the conveying rod 23.

[0030] In this structure, when the mixed powder coating enters the interior of the feeding barrel 4 through the discharge pipe 3, the second motor 22 drives the conveying rod 23 to operate and causes the feeding dragon to rotate, so that the powder coating inside the feeding barrel 4 is evenly discharged through the discharge pipe 5.

[0031] Working principle of this utility model:

[0032] When the above structure is used, when the powder coating is mixed by the mixer, the operator first pushes the dust cover 11, so that the two sliders 20 at the bottom of the dust cover 11 slide inside the slide groove 19 at the feeding port 6. At this time, the feeding port 6 is in an open state, and the powder coating can be added through the feeding port 6.

[0033] After the powder coating is added to the interior of the mixing box 1, the dust cover 11 is closed in the same manner. The setting of the dust cover 11 can reduce the dust generated during the mixing process of the powder coating from being blown out through the feeding port 6. At this time, the first motor 7 drives the rotating rod 8 to rotate inside the mixing box 1. The rotation of the rotating rod 8 drives the stirring rod 9 and the digging shovel 10 to rotate. In this process, the stirring rod 9 and the digging shovel 10 can mix the powder coating inside the mixing box 1, and the rotation of the digging shovel 10 can scoop up the powder coating from the bottom of the mixing box 1 and scatter it from top to bottom. The powder coating is continuously scattered from top to bottom, which can improve the mixing effect of the powder coating.

[0034] During the mixing process, the dust raised during the mixing is transported to the inside of the treatment box 12 through the dust conveying hose 15 by the dust suction pump 14, and then falls into the inside of the collection box 13. During this process, one end of the connecting pipe 18 is connected to the water source, so that the water enters the inside of the installation pipe 16 through the connecting pipe 18, and finally sprays into the inside of the treatment box 12 through the atomizing nozzle 17, so as to reduce the dust collected and reduce the environmental impact caused by the secondary dust.

[0035] The operator can remove the collection box 13 from the inside of the processing box 12 by loosening the bolt 27, and then process the collected dust. The bottom of the dust cover 11 is installed with a filter screen 21 by screws. The filter holes of the filter screen 21 are smaller than the powder coating particles, ensuring that the powder coating will not be sucked out along with the dust during the dust collection process, thereby achieving a dust removal effect on the powder coating and improving the later use effect of the powder coating.

[0036] After the powder coating is mixed, the solenoid valve at the discharge pipe 3 is opened. At this time, the mixed material enters the interior of the feed barrel 4 through the discharge pipe 3. The second motor 22 drives the conveying rod 23 to operate and causes the feed dragon to rotate, so that the powder coating inside the feed barrel 4 is evenly discharged through the discharge pipe 5.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
