DETAILED DESCRIPTION

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-4 , the present invention provides a technical solution: a paint grinding barrel, including an upper barrel body 1, a lower barrel body 2 is arranged below the upper barrel body 1, a feeding port 3 is opened on the upper barrel body 1, a servo motor 4 is installed on the upper barrel body 1, a driving rod 5 is installed at the output end of the servo motor 4, a driving block 6 is installed at the end of the driving rod 5 away from the servo motor 4, guide rails 8 are opened on the surface of the driving block 6 and the inner wall of the upper barrel body 1, balls 9 are arranged in the guide rails 8, a discharge hole 10 is opened on the driving block 6, a first grinding disc 11 is arranged below the driving block 6, a second grinding disc 13 is arranged inside the lower barrel body 2, a filter screen 14 is arranged on the second grinding disc 13, a receiving dish 17 is arranged below the second grinding disc 13, the receiving dish 17 is located inside the lower barrel body 2, a first cross plate 19 and a second cross plate 18 are respectively installed on the surfaces of the upper barrel body 1 and the lower barrel body 2, and a locking bolt 20 is installed on the second cross plate 18.

[0020] A concave structure is arranged in the middle of the driving block 6, and the concave structure is communicated with the discharge hole 10. The driving block 6 is rotationally connected with the upper barrel body 1 through the balls 9. A shielding piece 7 is arranged at the joint between the upper edge of the driving block 6 and the upper barrel body 1. The raw materials put into the upper barrel body 1 will pass through the concave in the middle of the driving block 6 and the discharge hole 10, and then pass through the through hole in the middle of the first grinding disc 11 and fall between the first grinding disc 11 and the second grinding disc 13 for grinding. The arrangement of the shielding piece 7 can prevent the paint raw materials from falling into the gap between the driving block 6 and the upper barrel body 1 from the upper edge of the driving block 6.

[0021] The first grinding disc 11 is nested below the driving block 6. A locking bolt 12 is installed at the edge of the first grinding disc 11. The first grinding disc 11 is connected with the driving block 6 through the locking bolt 12. A through hole is opened at the position corresponding to the discharge hole 10 on the first grinding disc 11, which is convenient for the first grinding disc 11 to be installed or disassembled below the driving block 6 through the locking bolt 12.

[0022] A clamping block 15 is arranged at the edge of the second grinding disc 13, a vertical groove 16 is opened on the inner wall of the lower barrel body 2, and the clamping block 15 is embedded in the vertical groove 16, which is convenient for the second grinding disc 13 to be stably installed in the lower barrel body 2 through the cooperation between the clamping block 15 and the vertical groove 16 to prevent dislocation.

[0023] The locking bolt 20 is rotatably connected to the second cross plate 18, and the locking bolt 20 is connected to the first cross plate 19 by a through-thread connection. When the locking bolt 20 is rotated on the second cross plate 18, the locking bolt 20 can push the first cross plate 19 closer to or away from the second cross plate 18 through the thread.

[0024] A sealing ring 21 is provided at the connection between the upper barrel body 1 and the lower barrel body 2. When the upper barrel body 1 and the lower barrel body 2 are aligned and butted, the sealing ring 21 can improve the sealing performance between the upper barrel body 1 and the lower barrel body 2 and prevent the coating raw material from leaking between the upper barrel body 1 and the lower barrel body 2.

[0025] Working principle: First, the coating raw material is put into the upper barrel body 1 from the feeding port 3, and then the raw material will flow into the space between the first grinding disc 11 and the second grinding disc 13 through the depression on the driving block 6. At this time, the servo motor 4 is started, and the servo motor 4 drives the driving block 6 to rotate in the upper barrel body 1 through the driving rod 5 and the ball 9. At the same time, the driving block 6 drives the first grinding disc 11 to rotate on the second grinding disc 13, so as to grind the coating between the first grinding disc 11 and the second grinding disc 13. The ground coating then falls into the receiving dish 17 in the lower barrel body 2 through the filter screen 14 for centralized collection;

[0026] When it is necessary to replace the first grinding disc 11 and the second grinding disc 13, the locking bolt 20 is rotated on the second cross plate 18. At this time, the rotating locking bolt 20 pushes the first cross plate 19 away from the second cross plate 18 through the thread, and the first cross plate 19 drives the upper barrel body 1 away from the lower barrel body 2. Then the locking bolt 12 can be unscrewed, and the first grinding disc 11 can be removed for replacement. The new first grinding disc 11 is also installed below the driving block 6 through the locking bolt 12. After the first grinding disc 11 is replaced, the clamping block 15 is taken out of the vertical groove 16, and the clamping block 15 drives the second grinding disc 13 to disengage from the lower barrel body 2. Then the new second grinding disc 13 is installed into the lower barrel body 2 through the clamping block 15 and the vertical groove 16. After both the first grinding disc 11 and the second grinding disc 13 are replaced, the locking bolt 20 is rotated in the reverse direction. At this time, the rotating locking bolt 20 pushes the first cross plate 19 closer to the second cross plate 18 until the upper barrel body 1 and the lower barrel body 2 are in butt contact, so that the upper barrel body 1 and the lower barrel body 2 are completed for fitting and butting.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
