Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment preservation, in particular to a novel coating grinding device. Background Art

[0002] When processing paint, it is necessary to grind the raw materials of the paint. At present, basket grinders are often used to grind the raw materials. The emergence of basket grinders is a supplement to the limitations of traditional grinding equipment such as horizontal sand mills and vertical sand mills. A grinding basket is fixed on the frame of the basket grinder, and a rotating shaft is passed through the grinding basket. A plurality of pins are fixedly connected to the rotating shaft in the grinding basket. The grinding basket is filled with grinding media such as zirconia beads, and an impeller is fixedly connected to the bottom end of the rotating shaft. When working, the grinding basket is immersed in the liquid material, and the rotating shaft is driven by a motor to rotate at a high speed, so that the impeller generates a strong suction force. The suction force generated by the impeller continuously sucks the material into the grinding basket, and the pins and zirconia beads cooperate to grind the material. The qualified material is squeezed out from the filter holes at the bottom of the grinding basket, and the material that does not meet the grinding standards is blocked in the grinding basket and continues to be ground by the pins and zirconia beads. The grinding machine structure of the above structure is very cleverly designed, but there are still disadvantages. Because in order to suck the material into the grinding basket, it is necessary to leave a circular material inlet between the upper cover of the grinding basket and the rotating shaft for the material to enter. When the rotating shaft rotates at high speed, the pin rod collides with the zirconia beads, and the zirconia beads are likely to be hit next to the material inlet. Since the rotating shaft and the grinding basket are in relative motion, the zirconia beads are easily stuck between the rotating shaft and the upper cover of the grinding basket, causing the inner edge of the upper cover of the grinding basket to bear a lot of friction. Over time, the material inlet will expand, making it easy for the zirconia beads to leak out, which is the common phenomenon of bead leakage and bead jamming in basket grinders.
