Description

Technical Field

[0001] The utility model belongs to the technical field of polishing powder detection, in particular to a polishing powder particle size detection device. Background Art

[0002] Polishing powder is typically composed of cerium-rich oxide, which is crushed into a fine powder through a gas-crushing process. This powder must be mixed with additives to form a suspension (polishing solution) before polishing testing can begin. The prepared emulsion is pumped to the test bench and sprayed onto the test part. The polishing test head and spray head rotate and move to polish the test part.

[0003] Polishing powder needs to be tested before use to ensure the polishing effect during use. However, when testing the polishing powder, centrifugal force is used to test the polishing powder. However, during use, due to the action of centrifugal force, the polishing powder will be thrown onto the inner wall of the filter, covering the mesh of the filter, so that the remaining polishing powder inside cannot be fully tested, affecting the overall test effect.

[0004] To this end, we propose a polishing powder particle size detection device to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0021] Reference Figure 1-Figure 3 A polishing powder particle size detection device includes a collecting drum 1, a screen drum 6 is rotatably mounted on the collecting drum 1, the screen drum 6 is rotatably mounted on the top surface of the collecting drum 1, the top of the collecting drum 1 is fixedly connected to a U-shaped frame 2 located above the screen drum 6, the inner bottom wall of the screen drum 6 is fixedly connected to a connecting shaft 11, the top of the connecting shaft 11 is rotatably mounted on the U-shaped frame, the upper end of the connecting shaft 11 is fixedly connected to a first bevel gear 8, and a second bevel gear 9 rotatably mounted on the connecting shaft 11 is provided below the first bevel gear 8, and a driving mechanism for the first bevel gear 8 is provided on one side of the U-shaped frame. The bevel gear 8 and the second bevel gear 9 drive assembly, and a turning assembly for turning the polishing powder on the inner wall of the sieve drum 6 is provided between the second bevel gear 9 and the connecting shaft 11. The inner bottom wall of the collecting drum 1 is provided with a collecting assembly for collecting the polishing powder after detection. The polishing powder to be detected is placed in the sieve drum 6, and the first bevel gear 8 is rotated by the driving assembly, and then the connecting shaft 11 and the sieve drum 6 are driven to rotate synchronously, and the polishing powder is released for screening and detection, and then the polishing powder attached to the inner wall of the sieve drum 6 is turned over by the turning assembly to improve the overall detection effect.

[0022] Reference Figure 3 The driving assembly includes two driving bevel gears 10 that are respectively engaged with the first bevel gear 8 and the second bevel gear 9. A rotating shaft 5 is installed to rotate through the U-frame. A fixing plate 4 for fixing the rotating shaft 5 is provided on the U-frame. The two driving bevel gears 10 are fixedly installed on the rotating shaft 5. A first motor 3 connected to the rotating shaft 5 is fixedly installed on one side of the U-frame. The rotating shaft 5 is driven by the first motor 3 to rotate, and the rotation of the rotating shaft 5 causes the two driving bevel gears 10 on the rotating shaft 5 to rotate. The two driving bevel gears 10 are respectively engaged with the two first bevel gears 8 and the second bevel gear 9, and the rotation directions of the first bevel gear 8 and the second bevel gear 9 are opposite. While the screen drum 6 rotates, the polishing powder attached to the inner wall of the screen drum 6 is peeled off by the flipping assembly.

[0023] Reference Figure 4 The flipping assembly includes a flipping plate 7 that fits the inner wall of the sieve cylinder 6. The bottom of the connecting shaft 11 is sleeved with a sleeve 14. The top of the flipping plate 7 is connected to the second bevel gear 9 and the bottom is connected to the sleeve 14. The rotation of the second bevel gear 9 causes the flipping plate 7 to flip the polishing powder attached to the inner wall of the sieve cylinder 6, so that the polishing powder attached to the inner wall of the sieve cylinder 6 can be peeled off by the flipping plate.

[0024] Reference Figure 3 The diameter of the first bevel gear 8 is smaller than that of the second bevel gear 9. During the rotation, differential motion is generated. While the screen drum 6 rotates rapidly, the turning plate 7 rotates slowly in the opposite direction to turn over the attached polishing powder, making it easier to detect the remaining polishing powder.

[0025] Reference Figure 3 Both sides of the turning plate 7 are inclined, and when the turning plate 7 rotates, it is easier to peel off the polishing powder attached to the inner wall of the sieve cylinder 6.

[0026] Reference Figure 4 The inner bottom wall of the collecting cylinder 1 is provided with a discharge port 15. The collecting assembly includes a discharge plate 12 rotatably mounted on the inner bottom wall of the collecting cylinder 1. The bottom and both ends of the discharge plate 12 are in contact with the inner wall of the collecting cylinder 1. The inner bottom wall of the collecting cylinder 1 is provided with a second motor 13 connected to the discharge plate 12. When the polishing powder after detection falls into the screen cylinder 6, the discharge plate 12 is driven to rotate by the second motor 13, and the polishing powder falling on the inner bottom wall of the screen cylinder 6 is pushed to the discharge port by the rotation of the discharge plate 12 for collection.

[0027] Working principle:

[0028] The polishing powder to be tested is placed in the sieve drum 6, and the rotating shaft 5 is rotated by the drive of the first motor 3. The rotation of the rotating shaft 5 rotates the two driving bevel gears 10 on the rotating shaft 5. The two driving bevel gears 10 respectively engage with the two first bevel gears 8 and the second bevel gear 9, and the rotation directions of the first bevel gear 8 and the second bevel gear 9 are opposite. When the second bevel gear 9 rotates, the flipping plate 7 flips the polishing powder attached to the inner wall of the sieve drum 6, so that the flipping plate can peel off the polishing powder attached to the inner wall of the sieve drum 6, and then re-test, thereby improving the overall detection effect.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
