Description

Technical Field

[0001] The invention relates to the technical field of metal grinding, and more specifically to a full-automatic circulating magnetic grinding device. Background Art

[0002] Metal is an indispensable material in modern industry and is widely used in machinery manufacturing, construction, automobile manufacturing and other fields. Metal is a chemical element with luster, good electrical and thermal conductivity, as well as forgeability and ductility. Metal needs to be ground during processing. When grinding metal particles, a fully automatic circulating magnetic grinding device is required.

[0004] In the above technical solution, small pieces of metal blocks can be repeatedly ground, which is also convenient for subsequent packaging. However, the traditional partial metal particle grinding device uses a grinding roller to grind the metal particles. Due to the repeated movement of the grinding roller, the metal particles will diffuse axially to the grinding roller, causing the metal particles to diffuse to the inner wall of the grinding disk, resulting in the grinding roller failing to grind or incompletely grinding the metal particles at the boundary. In order to solve this problem, human intervention is required to center the metal particles, which not only increases the difficulty of operation, but also affects the grinding speed and efficiency of the metal particles.

In order to prevent the granular metal particles from accumulating, the rotating shaft rotates with the push rod. When the push rod squeezes the ramp block, the filter disc moves upward with the slider in the slide to squeeze the second spring. When the push rod does not squeeze the ramp block, the filter disc is reset under the action of the second spring, so that the granular metal inside the filter disc falls through the filter port, which not only prevents the metal particles from accumulating inside the filter disc, but also ensures the orderly discharge of the granular metal.
