Combined multi-stage rotary paint powder sanding device

Abstract

The invention relates to the technical field of paint, and discloses a combined multi-stage rotary paint powder sanding device. The combined multi-stage rotary paint powder sanding device comprises abase, a control console is fixedly connected to the top of the base, a supporting frame is fixedly connected to the top of the base, a main shaft is movably connected into the supporting frame, the outside of the main shaft is fixedly connected with a knock out pin, the outside of the main shaft is fixedly connected with a crushing ball, the outside of the crushing ball is fixedly connected with acounterweight, the right end of the main shaft is fixedly connected with a sleeve shaft, and a feeding inlet is movably connected into the sleeve shaft. Thorough cooperative use of the supporting frame, the main shaft, the knock out pin rod, the crushing ball, the counterweight and an inner shell, the effect of increasing collision is achieved, the efficiency of the movement of a medium inside the inner shell is improved, a collision mechanism and a collision method of the medium inside the inner shell are effectively increased, the crushing speed and crushing effect of the paint powder are improved, and the efficiency and quality of the paint powder grinding are effectively improved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a combined multi-stage rotating coating powder sanding device. Background technique [0002] Paint, traditionally called paint in China. The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. [0003] In the coating powder processing process, it is usually necessary to use a sand mill to grind the coating, and the existing sand mill is equipped with media for grinding such as zirconium beads, glass beads, etc. in a closed cylinder. The dispersing disc on the top moves the medium in the cylinder to make the media move relative to each other, allowing the materials to be ground to pass through t...

AI Technical Summary

Problems solved by technology

[0003] In the coating powder processing process, it is usually necessary to use a sand mill to grind the coating, and the existing sand mill is equipped with media for grinding such as zirconium beads, glass beads, etc. in a closed cylinder. The dispersing disc on the top moves the medium in the cylinder to make the media move relative to each other, allowing the materials to be ground to pass through the media to achieve the effect of crushing. The movement of the media is caused only by the distributing disc on the rotating shaft. The efficiency and collision effect are poor, which leads to the low grinding efficiency and unsatisfactory grinding effect of the existing sand mill, and the poor heat dissipation effect of the existing sand mill further limits the grinding efficiency of the sand mill
