Paint grinder that avoids bead buildup

Abstract

The invention discloses an oil paint grinding machine capable of preventing grinding beads from being accumulated. The oil paint grinding machine structurally comprises a main shaft, a feeding pipe, discs, a grinding ball inlet, a cooling water outlet, a discharge port, an anti-fracture structure, a transmission belt wheel and a shell. The feeding pipe is obliquely arranged on one side of the shell, the shell is of a cylindrical structure and the main shaft is horizontally arranged in the center of the shell, the more than two discs are arranged on the main shaft, the other end of the main shaft penetrating the shell is joined and fixed to the transmission belt wheel, the grinding ball inlet, the cooling water outlet and the discharge port are successively formed from the end, close to thefeeding pipe, to the other end of the shell, the anti-fracture structure is arranged in the shell below the discharge port, and the anti-fracture structure is also slidably matched with the main shaft. The oil paint grinding machine cleans the grinding balls below the discharge port by matching a spiral spring disc with a rebound plate primarily, and meanwhile, a second spring and a first springof the spiral spring disc and a clamping rod are designed to break pigment aggregate particles moving below the discharge port can be crushed, so that the fusing effect is enhanced.

Description

technical field [0001] The invention relates to the field of paint grinding, in particular to a paint grinder which avoids the accumulation of grinding beads. Background technique [0002] The paint preparation process on the market mainly crushes and disperses the pigment solid particles in the resin solution or emulsion by external force to form a uniform and fine suspension dispersion, and the preparation process is mainly divided into pre-dispersion--grinding and dispersion- - Paint mixing--purifying and packaging four processes. Grinding and dispersion is the standard to ensure the quality of the paint. If the paint is dispersed too uniformly or unevenly, the fit between the finished product and the wall will be poor. Grinding and dispersion use grinding beads for grinding. , At present, the grinding beads are piled up at the bottom of the sand mill, and the speed of the working pump is too fast, which causes the grinding beads to be concentrated at the outlet of the ho...

[0002] The paint preparation process on the market mainly breaks and disperses the pigment solid particles in the resin solution or emulsion by external force to form a uniform and fine suspension dispersion, and the preparation process is mainly divided into pre-dispersion-grinding dispersion- -Painting--Purification and packaging four processes. Grinding and dispersing is the standard to ensure the quality of the paint. If the paint is dispersed too uniformly or unevenly, the adhesion between the finished product and the wall will be poor. Grinding and dispersing use grinding beads for grinding At present, the grinding beads are accumulated at the bottom of the sand mill, and the excessively fast speed of the working pump causes the grinding beads to be concentrated at the outlet of the horizontal sand mill, that is, the phenomenon of "grinding beads backlog", and the grinding beads will be crushed under force
