Abstract
Description
Technical Field
[0001] The present application relates to the technical field of powder material grinding devices, and in particular to a coating powder grinding device. Background Art
[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigment, filler and additives. Unlike ordinary solvent-based coatings and water-based coatings, its dispersion medium is air instead of solvent and water. It has the characteristics of no solvent pollution, 100% film formation and low energy consumption. Powder coatings are divided into two categories: thermoplastic and thermosetting. Thermoplastic powder coatings have poor coating appearance (gloss and leveling) and poor adhesion to metal, so they are rarely used in the field of automotive coating. Automotive coating generally uses thermosetting powder coatings. Thermosetting powder coatings use thermosetting synthetic resins as film-forming materials. During the drying process, the resin first melts and then solidifies into a smooth and hard coating after chemical cross-linking.
[0003] The existing patent (publication number: CN216826455U) discloses a fire retardant coating powder grinding device, including a grinding cylinder, the inner wall of the grinding cylinder is fixedly connected to a connecting rod, the grinding cylinder is fixedly connected to a lower grinding disc through the connecting rod, the upper part of the lower grinding disc is rotatably connected to an upper grinding disc through a bearing, a feed through hole is opened on the surface of the upper grinding disc, a feed hopper is connected to the position above the upper grinding disc opposite to the opening of the feed through hole, and a driving mechanism is connected to the grinding cylinder.
[0004] The above-mentioned comparative document points out that the utility model makes the whole grinding process more automated by setting a driving component, thereby avoiding the time-consuming and labor-intensive phenomenon caused by manual grinding, and further does not affect the addition of materials during the whole grinding process; and by setting a material guide hopper, a filter screen and a processing port, the ground paint can be further filtered and processed, avoiding the mixing of unqualified paint, thereby improving the efficiency of paint grinding. However, during the grinding process of the device, the material will be squeezed and accumulated on both sides of the grinding disk, and the grinding disk will not be able to grind the scraps, causing the scraps to accumulate, and the device is not convenient for the staff to clean and recycle when the material leaks onto the filter screen.

[0007] Through the above scheme, the air pump is started simultaneously during the grinding process, and the gas is blown to the inner periphery of the grinder through the air outlet head, so that the coating is always kept within the range of the grinding rod to prevent uneven grinding. At this time, the powder will fall onto the filter through the through holes on the grinding plate. By installing slide rails on both sides of the filter, when the filter needs to be cleaned, the staff can directly pull the filter out and reverse it through the handle for cleaning.
[0008] Furthermore, a feed port is fixedly connected to the upper end of the grinder.
[0009] According to the above scheme, the grinding machine is fed by setting a feed inlet.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0023] The paint powder grinding device starts the air pump simultaneously during the grinding process, and the gas is blown to the inner periphery of the grinder through the air outlet head, so that the paint is always kept within the range of the grinding rod to prevent uneven grinding. At this time, the powder will fall onto the filter through the through holes on the grinding plate. By installing slide rails on both sides of the filter, when the filter needs to be cleaned, the staff directly pulls out the filter through the handle and reverses it for cleaning. After the filter is filtered, the qualified powder finally falls into the collection box through the discharge port. BRIEF DESCRIPTION OF THE DRAWINGS

A fixed frame 16 is fixedly connected, a filter screen 17 is fixedly connected inside the fixed frame 16, and a handle 18 is fixedly connected to one side of the fixed frame 16. The handle 18 is provided to facilitate the work of the staff. During the grinding process, the air pump 6 is started at the same time, and the gas is blown to the inner periphery of the grinder 3 through the air outlet head 9, so that the paint is always kept within the range of the grinding rod to prevent uneven grinding. At this time, the powder will fall onto the filter screen 17 through the through holes on the grinding plate 22. By installing slide rails 14 on both sides of the filter screen 17, when the filter screen 17 needs to be cleaned, the staff directly pulls the filter screen 17 out in reverse through the handle 18 for cleaning.
[0032] See also Figure 1 , Figure 2 and Figure 3 A motor 4 is fixedly connected to the upper end of the grinder 3, and the output end of the motor 4 passes through one side of the grinder 3 and is fixedly connected to a rotating shaft 19. A coarse grinding rod 20 is fixedly connected to the outer wall of the rotating shaft 19, and large particles of powder are ground by setting the coarse grinding rod 20. A fine grinding rod 21 is fixedly connected to the outer wall of the rotating shaft 19 away from the coarse grinding rod 20, and small particles of powder are ground by setting the fine grinding rod 21.

The coarse grinding rod 20 and the fine grinding rod 21 cooperate to grind, thereby achieving the grinding effect and making the grinding effect better. During the grinding process, the air pump 6 is started at the same time, and the gas is blown to the inner periphery of the grinder 3 through the air outlet head 9, so that the coating is always kept within the range of the grinding rod to prevent uneven grinding. At this time, the powder will fall onto the filter screen 17 through the through holes on the grinding plate 22.

After the filter screen 17 is filtered, the qualified powder finally falls into the collection box 11 through the discharge port 10.
