The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0038] Example 1

[0039] See also Figure 1 and Figure 2 , this embodiment provides a coating grinding device, comprising:

[0040] Collection box 100; Figure 1As shown, a collecting chamber 130 is longitudinally provided on the side end surface of the collecting box 100, a filter drawer 200 is slidably connected in the collecting chamber 130, and a collecting drawer 300 is slidably connected in the collecting chamber 130 near the filter drawer 200, the filter drawer 200 is stacked directly above the collecting drawer 300, and both the filter drawer 200 and the collecting drawer 300 can be taken out from the collecting chamber 130, the width of the filter drawer 200 is smaller than the width of the collecting drawer 300, and a gap is left between the filter drawer 200 and the two side walls of the collecting chamber 130.

[0041] like Figure 2 The top surface of the collection box 100 is provided with a mounting portion 110, and an annular through hole 113 is opened on the top surface of the collection box 100 surrounding the mounting portion 110. The first motor 511 is fixedly installed on the surface of the mounting portion 110, and the output shaft of the first motor 511 is fixedly connected to the grinding roller 500. A grinding sleeve 400 is coaxially sleeved on the outer surface of the grinding roller 500, and the bottom of the grinding sleeve 400 is fixedly connected to the top surface of the collection box 100.

[0042] In some embodiments, the grinding sleeve 400 includes a first grinding part 401, a falling part 402 and a discharge cavity 410, the discharge cavity 410 is arranged at the top of the first grinding part 401, the falling part 402 is arranged at the bottom of the discharge cavity 410, and the inner wall of the first grinding part 401 is provided with grinding protrusion particles.

[0043] In some embodiments, the grinding roller 500 includes a hemispherical convex portion 501 and a second grinding portion 502, wherein the hemispherical convex portion 501 is fixedly arranged at the top end of the second grinding portion 502, and the surface of the second grinding portion 502 is fixedly provided with grinding protrusion particles, wherein the hemispherical convex portion 501 is located in the middle of the discharge cavity 410. Since the hemispherical convex portion 501 is located in the middle of the discharge cavity 410, when the paint to be ground is added, the grinding roller 500 drives the hemispherical convex portion 501 to rotate, so that the paint can more easily enter the grinding sleeve 400 and the grinding portion set by the grinding roller 500. When the grinding roller 500 is driven by the motor to grind the paint, the outer wall of the grinding portion of the grinding roller 500 can grind the paint, so that the grinding efficiency is higher.

[0044] It should be noted that the second grinding portion 502 is coaxially arranged with the first grinding portion 401 , and the vertical height of the first grinding portion 401 is the same as the height of the first grinding portion 401 ; the annular sleeve 510 is coaxially arranged with the shedding portion 402 .

[0045] In some embodiments, a fixing pin 111 is disposed on the top surface of the mounting portion 110, and the fixing pin 111 is annularly disposed on the top surface of the mounting portion 110. The fixing pin 111 is fixedly connected to the annular sleeve 510, and the top surface of the annular sleeve 510 contacts the bottom end surface of the second grinding portion 502. The outer wall surface of the annular sleeve 510 is smooth, and the annular sleeve 510 is coaxially disposed with the shedding portion 402. The annular gap formed between the annular sleeve 510 and the shedding portion 402 is more conducive to the smooth shedding of the ground paint into the collection chamber 130, and further prevents the ground paint from clogging the through hole.

[0046] The grinding sleeve 400 is coaxially arranged with the grinding roller 500, and the inner wall of the grinding sleeve 400 and the outer wall of the grinding roller 500 are provided with grinding protrusion particles, so that the paint is ground under the drive of the motor. Since the paint grinding process is carried out in the vertical ring of the grinding sleeve 400 and the grinding roller 500, the paint is not easily spilled and wasted. At the same time, during the grinding process, the paint moves slowly downward due to its own gravity, and the uniformly ground paint will not be compressed, so that the ground paint is more uniform.
