[0002] UV curing coatings can be applied to ink printing and exposed to UV radiation. Their solid content can be as high as 100%, so there is no volatile component and no pollution to the environment. The high solid content also allows them to be applied to very thin films. When grinding UV coatings, a sand mill is needed. When using existing sand mills, the UV coatings are ground by stirring or rolling. This method has extremely low grinding efficiency and requires manual discharge, so it needs to be improved.

[0003] In view of the above problems, in the prior art, patent announcement number CN217699383U discloses a sand mill for the production of UV coatings, including a machine body, a first motor box is fixedly connected to the inside of the machine body, a first motor is arranged inside the first motor box, a material box is fixedly connected to the top of the first motor box, a barrel is fixedly connected to the output end of the first motor, a frosted protrusion is fixedly connected to the inner wall of the barrel, a cavity is opened at the bottom of the barrel, and a filter is fixedly connected to the inside of the cavity. The utility model has the following advantages and effects: when the UV coating comes into contact with the frosted protrusion and the frosted layer, the barrel and the roller rotate with each other to cooperate, thereby rubbing and squeezing the UV coating, squeezing the UV coating into powder, thereby achieving the purpose of grinding, greatly improving the grinding efficiency of the UV coating, and the powdered UV coating enters the inside of the material box through the mesh inside the filter for storage.

[0004] The above technical solution solves the problems raised in the above background technology, but the filter of the above prior art is installed at the lower end of the barrel. During operation, the paint powder is easily deposited on the filter, which leads to blockage of the filter. Therefore, a sand grinder for UV paint production that solves the above problems is needed. Utility Model Content

[0011] Beneficial effects:

[0012] The utility model provides a sand grinder for UV coating production, which has the following beneficial effects. Through its structural design, the device drives the cone part to rotate through the power motor on the top of the grinding cylinder on the installation box, and then drives the frosted layer to rotate, and then the feed is fed through the feed pipe and guided by the cone part to flow to the frosted layer, and then the coating is ground by the frosted layer and the grinding cylinder, and the ground coating falls into the rotating box. Since the rotating box rotates synchronously under the action of the frosted layer, the coating in the rotating box is thrown out through the filter screen under the centrifugal action, and the clogging of the filter screen is further avoided by cooperating with the tossing action of the tossing rod. The thrown coating is discharged through the discharge pipe in the rotating box, which solves the problem that the filter screen is easily blocked in the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In the utility model, the inner wall of the grinding cylinder 2 is evenly provided with frosted protrusions 11, and the grinding structure is formed by the cooperation of the frosted protrusions 11 and the frosted layer 5.

[0021] In the utility model, a guide plate 12 is installed in the lower part of the installation box 1. The guide plate 12 is a plate-like structure that tilts downward from the section away from the discharge pipe 10 to the end close to the discharge pipe 10. The paint is guided by the inclined guide plate 12 under the action of gravity.

[0022] In the utility model, both ends of the guide plate 12 are connected to the mounting box 1 through a flexible connecting plate 13, a spring 14 is installed on the high side of the guide plate 12, the upper end of the spring 14 is connected to the guide plate 12, and the lower end of the spring 14 is connected to the mounting box 1, and an extrusion protrusion 15 is installed on the lower outer side of the rotating box 6.

The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control.

[0025] In this embodiment:

[0026] During operation, the power motor 3 on the top of the grinding cylinder 2 installed on the box 1 drives the conical part 4 to rotate, and then drives the frosted layer 5 to rotate, and then the feed is fed through the feed pipe 9, guided by the conical part 4 and then flows to the frosted layer 5, and then the frosted layer 5 and the grinding cylinder 2 grind the paint, and the ground paint falls into the rotating box 6. Since the rotating box 6 rotates synchronously under the action of the frosted layer 5, the paint in the rotating box 6 is thrown out through the filter screen 7 under the action of the centrifugal force, and the blocking of the filter screen 7 is further avoided by cooperating with the driving action of the lever 8, and the thrown paint is discharged through the discharge pipe 10 in the rotating box 6.
