Description

Technical Field

[0001] This utility model relates to the technical field of powder coating processing equipment, specifically to a sieving device for powder coating production. Background Technology

[0002] Powder coating is a new type of solvent-free solid powder coating. It has the advantages of being solvent-free, pollution-free, recyclable, environmentally friendly, and energy-saving. It is now used in various industries. Powder coating is safer and more convenient to store and transport than liquid coating. In addition, the special odor generated during the spraying process is also easy to evaporate, making it safe and reliable.

[0003] In the powder coating production process, the diameter of the final product needs to be strictly controlled. Therefore, the finished powder coating needs to be screened in the final production process to separate it into powder coatings of different diameters. Currently, flat plate screens are mostly used to screen the coatings, which cannot efficiently separate powder coating particles of different sizes. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a sieving device for powder coating production. This device solves the problem that current methods of sieving coatings often use flat sieves, which cannot efficiently separate powder coating particles of different sizes.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sieving device for powder coating production includes a sieving box, a feeding box above the sieving box, a conveying motor on one side of the feeding box, a conveying shaft extending from the output end of the conveying motor into the feeding box, spiral blades sleeved on the outer side of the conveying shaft, a sieving motor at the top of the sieving box, a drive shaft extending from the output end of the sieving motor into the sieving box, two opposing stirring blades on the drive shaft, a support plate connected to the drive shaft at the top of the sieving box, a collection box connected to the sieving box at the bottom, two opposing support plates at the bottom of the collection box, a partition plate between the two support plates connected to the bottom of the support plate at the top, a plurality of evenly distributed first sieve holes penetrating through the support plate on one side of the partition plate, and a plurality of evenly distributed second sieve holes with a diameter larger than the first sieve holes penetrating through the support plate on the other side of the partition plate.

[0007] As a preferred embodiment of this utility model, the top of the feeding box is provided with a feeding pipe connected thereto.

[0008] As a preferred embodiment of this utility model, a guide pipe is provided between the screening box and the feeding box, with one end of the guide pipe inserted into the screening box and the other end inserted into the feeding box.

[0009] As a preferred technical solution of this utility model, each side of the partition plate is provided with a guide plate whose bottom end overlaps the top of the support plate, and the guide plate gradually slopes downward from the end closer to the partition plate to the end farther away from the partition plate.

[0010] As a preferred embodiment of this utility model, a third sieve hole is provided through the guide plate, and the diameters of the third sieve holes on the two guide plates are different.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In operation, powder coating is fed into the feeding box through the feed pipe. The conveyor motor drives the spiral blades, causing the powder coating to move and enter the screening box through the guide pipe, falling onto the support plate. Smaller powder coating particles pass through the first screen hole and fall onto one of the guide plates. These smaller particles roll on the inclined guide plates. Some powder coating passes through the third screen hole on the guide plate and falls to the bottom of the collection box between the support plate and the partition plate. The remaining powder coating falls along the guide plate into the area between the partition plate and the inner wall of the collection box, thus processing the smaller powder coating particles. The final coating material undergoes a second sieving. After a set time, the sieving motor is activated, driving the stirring blades to rotate the larger-sized powder coating material that cannot pass through the first sieve hole. This causes the larger-sized powder coating material to pass through the second sieve hole and fall onto another guide plate. The larger-sized powder coating material rolls on the guide plate, with some falling through the third sieve hole into the bottom of the collection box between the support plate and the partition plate. The remaining powder coating material falls along the guide plate into the area between the partition plate and the inner wall of the collection box, thus further sieving the larger-sized powder coating material. This invention enables multiple sieving of powder coating material, allowing for the selection of powder coating material with different particle sizes as needed. Attached Figure Description

[0019] Example

[0020] This utility model provides a sieving device for powder coating production, see reference. Figure 1-3 As shown, the device includes a screening box 4, with a feeding box 1 above the screening box 4. A conveying motor 2 is located on one side of the feeding box 1, and the output end of the conveying motor 2 extends into the feeding box 1 to form a conveying shaft 17. A spiral blade 18 is fitted on the outside of the conveying shaft 17. The feeding box 1 is designed to prevent clogging during the conveying of powder coatings.

[0021] The feeding box 1 has a feeding pipe 3 connected to its top side, which makes it easier for workers to put powder coating into the feeding box 1.

[0022] A guide pipe 6 is provided between the screening box 4 and the feeding box 1. One end of the guide pipe 6 is inserted into the screening box 4, and the other end of the guide pipe 6 is inserted into the feeding box 1.

[0023] The sieving box 4 is equipped with a sieving motor 5 at its top. The output end of the sieving motor 5 extends into the sieving box 4 and is equipped with a drive shaft 8. The drive shaft 8 is equipped with two opposing stirring blades 12. The stirring blades 12 can drive the powder coating to rotate and move. The sieving box 4 is equipped with a support plate 9 whose top is connected to the drive shaft 8. The sieving box 4 is equipped with a collection box 7 connected to it at the bottom. The bottom of the inner cavity of the collection box 7 is equipped with two opposing support plates 14. Between the two support plates 14 is a partition plate 13 whose top is connected to the bottom of the support plate 9. Several evenly distributed first sieve holes 11 are opened through the support plate 9 on one side of the partition plate 13. Several evenly distributed second sieve holes 10 with a diameter larger than the first sieve holes 11 are opened through the support plate 9 on the other side of the partition plate 13. The powder coating can be sieved by the arrangement of the first sieve holes 11 and the second sieve holes 10 on the support plate 9.

[0024] Furthermore, each side of the partition plate 13 is provided with a guide plate 15 with one end of its bottom overlapping the top of the support plate 14. The guide plate 15 gradually slopes downward from the end near the partition plate 13 to the end away from the partition plate 13, and the two guide plates 15 are respectively located below the first screen hole 11 and the second screen hole 10.

[0025] Furthermore, a third sieve hole 16 is provided through the guide plate 15, and the diameters of the third sieve holes 16 on the two guide plates 15 are different. Specifically, the diameter of the third sieve hole 16 on the guide plate 15 below the first sieve hole 11 is smaller than the diameter of the third sieve hole 16 on the guide plate 15 below the second sieve hole 10. By setting the third sieve hole 16 on the guide plate 15, the powder coating after being screened by the first sieve hole 11 and the second sieve hole 10 can be screened again, and four different particle sizes of powder coating can be screened out.

[0026] The working principle of this utility model is as follows:

[0027] In use, powder coating is fed into the feeding box 1 through the feed pipe 3. The conveyor motor 2 is started to drive the spiral blades 18 to move the powder coating. It enters the screening box 4 through the guide pipe 6 and falls onto the support plate 9. Smaller powder coatings pass through the first screen hole 11 and fall onto one of the guide plates 15. The smaller powder coatings roll on the inclined guide plate 15. Some of the powder coatings fall through the third screen hole 16 on the guide plate 15 to the bottom of the collection box 7 between the support plate 14 and the partition plate 13. The other part of the powder coatings falls along the guide plate 15 into the area between the partition plate 13 and the inner wall of the collection box 7, thus sorting out the smaller powder coatings. The powder coating undergoes a second sieving process. After a set time, the sieving motor 5 is activated, driving the stirring blades 12 to rotate the larger-sized powder coatings that cannot pass through the first sieve hole 11. This causes the larger-sized powder coatings to pass through the second sieve hole 10 and fall onto another guide plate 15. The larger-sized powder coatings roll on the guide plate 15, with some falling through the third sieve hole 16 on the guide plate 15 to the bottom of the collection box 7 between the support plate 14 and the partition plate 13. The other part of the powder coating falls along the guide plate 15 into the area between the partition plate 13 and the inner wall of the collection box 7, thus further sieving the larger-sized powder coatings. This invention enables multiple sieving of powder coatings, allowing for the selection of powder coatings with different particle sizes as needed.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
