Marble sorting device used for PVD coating device

Abstract

The invention discloses a marble sorting device used for a PVC coating device. The marble sorting device comprises a transmission part, a sorting part and collecting parts, wherein the transmission part is used for conveying marbles to the front end of the sorting part; the sorting part comprises a supporting assembly, a drive assembly and a sorting barrel; the supporting assembly is used for bearing and rotatably connecting the sorting barrel which rotates around the axis; the drive assembly is arranged on the supporting assembly and is in transmission connection to the sorting barrel, and isused for driving the sorting barrel to rotate around the axis; a plurality of sorting holes are uniformly distributed in the inner wall surface of the sorting barrel, and hole diameters of the sorting holes are gradually increased from the front end of the sorting barrel to the tail end of the sorting barrel; the front end of the sorting barrel is used for receiving the marbles conveyed by the transmission part; and the collecting parts are arranged below the sorting barrel and at the tail end of the sorting barrel for receiving and sorting the marbles sorted by the sorting barrel. The deviceintegrally realizes automatic marble sorting, and solves the manual marble sorting problem at present.

Description

technical field [0001] The invention belongs to the technical field of marble sorting, and in particular relates to a marble sorting device used for a PVD coating device. Background technique [0002] With the development of the coating industry, people have higher and higher requirements for tool coatings, which not only require the coating to have better performance, but also require that the coating on the tool after coating the cylindrical tool of the same specification The traces need to be at the same height. For this reason, enterprise factories generally choose to use marbles to be placed in the fixture to adjust the traces of the coating. However, after the coating technology, the marbles of different specifications used will be mixed together, which is not easy to distinguish, which will affect the next use. Marbles of different sizes are usually sorted manually, but this is time-consuming and labor-intensive. Contents of the invention [0003] The technical p...
