Description

Technical Field

[0001] The utility model belongs to the technical field of coating production, and particularly relates to a coating production raw material grinding device. Background Art

[0002] In the production process of paint, the paint raw materials need to be ground into fine powder that meets the requirements before they can be mixed and stirred to make the required paint liquid.

[0003] A Chinese patent with publication number CN220478911U discloses a paint production grinding device, including a shell, a feed inlet for paint raw materials to enter is opened on the top of the shell, and a grinding roller is arranged inside the shell, a filter plate with an inclined design is arranged below the shell, and the filter plate can shake inside the shell under the action of a reciprocating component, and the filter plate is provided with filter holes for particles that meet the radius requirements to pass through, and a guide plate is fixedly installed on the inner wall of the shell, and a sliding plate is slid inside the guide plate through a connecting spring, and the end of the sliding plate away from the guide plate is movably connected to the filter plate.

[0004] It can be understood from the paint production grinding device in the above-mentioned prior art that the device still has some shortcomings in actual use. For example, the paint raw material particles enter the two grinding rollers through the lower port of the feed plate and are ground into powder under the action of the two grinding rollers. However, if too much raw material is added to the feed port at one time, some of the raw materials will easily remain in the feed plate of the feed port. If only a little is added each time through the feed port and ground in the grinding rollers, it will consume a lot of manpower, so it is very inconvenient to use. Secondly, after the raw materials are ground and filtered, they are scattered and gathered in the collection bin, which is not convenient for centralized collection and removal for use.
