Unlike ordinary solvent-based and water-based coatings, their dispersion medium is not solvent or water. They are characterized by no solvent pollution and low energy consumption.

[0003] Existing patent CN222523721U discloses a powder coating quantitative feeding mechanism, including an electronic weighing platform. A hopper is fixedly installed on the upper surface of the electronic weighing platform, and a feeding cylinder is fixedly embedded inside the hopper. Two first bearings are fixedly embedded in the inner wall of the feeding cylinder, and the inner rings of the two first bearings are fixedly connected to a spiral feeding shaft. A discharge pipe is fixedly connected to the bottom end of the feeding cylinder. This powder coating quantitative feeding mechanism has a structure for quantitatively feeding powder coating.

[0004] However, the feeding mechanism still has some defects. During use, the powder coating is prone to clumping, which can cause the screw feeder shaft to jam during feeding, resulting in uneven output. This makes it inconvenient to control the feeding amount and makes it difficult to accurately control the feeding amount.

[0033] The top of both sides of the feed hopper 22 is equipped with shielding components;

[0034] A discharge assembly is installed at the bottom of the first discharge port 12.

[0035] In this embodiment, powder is fed into the interior of the first conveying auger 1 through the first feed port 11, the powder is conveyed by the operation of the first conveying auger 1, the powder is discharged through the first discharge port 12, the overall weight is weighed by the electronic weighing platform 17, so as to facilitate the weighing and detection of the discharge amount of the rubber hopper 35, the powder coating is collected through the feed hopper 22, the powder is crushed by the roller crusher 21, and collected by the storage box 2.

[0036] In one embodiment, such as Figure 1 and Figure 2 As shown, the conveying assembly includes a second conveying auger 13, which is installed on the right side of the first conveying auger 1. A second feed inlet 14 is installed on the top right side of the second conveying auger 13, a guide plate 15 is installed on the top left side of the second feed inlet 14, and a second discharge outlet 16 is installed on the bottom left side of the second conveying auger 13. The powder is accurately conveyed by the second conveying auger 13, avoiding the problem of insufficient feeding accuracy.

[0037] In one embodiment, such as Figure 1 and Figure 3 As shown, the shielding assembly includes a slide rail 23, a slide plate 24 is slidably connected inside the slide rail 23, and a cover plate 25 is installed on the top of the slide plate 24. By sliding the slide plate 24 inside the slide rail 23, the cover plate 25 is driven to cover the top.

[0038] In one embodiment, such as Figure 1 and Figure 3 As shown, a drive assembly is installed at the top center of the cover plate 25, which pushes the cover plate 25 to move.

[0039] In one embodiment, such as Figure 1 and Figure 3 As shown, the drive assembly includes a support frame 26, inside which a first electric push rod 27 is installed. A side plate 28 is installed at the output end of the first electric push rod 27. The side plate 28 is installed on the rear side of the feed hopper 22. By operating the first electric push rod 27 inside the support frame 26, the blocking assembly moves to cover.

[0040] In one embodiment, such as Figure 1 , Figure 2 and Figure 4As shown, the discharge assembly includes a discharge trough 3, which is installed at the bottom of the first discharge port 12. A discharge hopper 34 is installed at the bottom of the discharge trough 3, and a rubber hopper 35 is installed at the bottom of the discharge hopper 34. The powder is discharged through the discharge trough 3 and the discharge hopper 34 at the bottom of the discharge trough 3, and then buffered by the rubber hopper 35.

[0041] In one embodiment, such as Figure 1 and Figure 4 As shown, a sealing assembly is installed on the right side of the discharge trough 3.

[0042] In one embodiment, such as Figure 1 and Figure 4 As shown, the sealing assembly includes a fixing frame 31, which is installed on the right side of the discharge trough 3. A second electric push rod 32 is installed inside the fixing frame 31. A sealing plate 33 is installed at the output end of the second electric push rod 32. The sealing plate 33 is slidably connected to one side of the inside of the discharge trough 3.

[0043] The above embodiment discloses a powder coating quantitative feeding mechanism. The powder coating is placed inside the feed hopper 22. The operation of the first electric push rod 27 inside the support frame 26 causes the cover plate 25 to slide within the slide rail 23 via two sliding plates 24, thereby sealing the top of the feed hopper 22 and preventing large-scale dust generation during the crushing of agglomerated powder. After being crushed by the roller crusher 21, the powder is fed into the storage box 2. The bottom of the storage box 2 is connected to the first feed inlet 11 and the second feed inlet 14. The entire device is weighed by an electronic weighing platform 17, facilitating precise control of the powder weight fed from the rubber hopper 35. The powder is guided by the guide plate 15 and fed into the first feed inlet 11 and the second feed inlet 14. The operation of the first conveying auger 1 further controls the powder's weight. After being conveyed, the powder is discharged through the first discharge port 12. When precise control of the powder weight is required, the operation of the second electric push rod 32 inside the fixed frame 31 pushes the sealing plate 33 to seal the first discharge port 12, preventing powder from falling into the first discharge port 12 during the conveying process of the second conveying auger 13 and affecting the weight control. The powder coating is conveyed by the operation of the second conveying auger 13. Since the inner diameter of the second conveying auger 13 is smaller than that of the first conveying auger 1, the amount of powder delivered each time is smaller than that of the first conveying auger 1, which facilitates the improvement of feeding accuracy. The powder coating is delivered through the second discharge port 16, which improves the practicality of the device and avoids the problem of insufficient feeding accuracy. The discharge speed of the powder coating is buffered by the rubber hopper 35 at the bottom of the discharge hopper 34, avoiding the problem of large-area dust during discharge.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
