Powder uniform mixing equipment for electric brush production and mixing method

Abstract

The invention discloses powder uniform mixing equipment for electric brush production and a mixing method, wherein the powder uniform mixing equipment for electric brush production comprises a treatment box; a mounting hole is formed in the top of the treatment box; the mounting hole is internally provided with a placing box of which the top is provided with an opening; the inner wall of the placing box is provided with a placing cover; a mounting groove and a first rotating groove are respectively formed in the inner walls at two sides of the treatment box; the mounting groove is internally provided with a stepping motor; an output shaft of the stepping motor is welded with a rotating shaft; the end, far away from the stepping motor, of the rotating shaft extends to the inside of the first rotating groove; the outer side of the rotating shaft is fixedly sleeved with a first bevel gear; the bottom of the placing box extends to the inside of the treatment box; and each of two sides of the bottom of the placing box is welded with a vertical plate. The powder uniform mixing equipment is high in practicability; and powder in the treatment box is primarily uniformly mixed by using a first screw rod and first stirring shafts and is further mixed by a draught fan and second stirring shafts, so that the powder mixing efficiency is effectively increased.

Description

technical field [0001] The invention relates to the technical field of mixing equipment, in particular to a powder mixing equipment and a mixing method for brush production. Background technique [0002] In colored brushes, there are ferrous metals, mainly copper powder, silver powder, followed by lead powder, tin powder, lead oxide powder, etc., and the balance is flake graphite powder. The content of various metal powders depends on the technical requirements of the brush. When the metal content reaches a certain amount, no binder can be added, and the powder can be directly pressed into shape after mixing. When producing electric brushes, it is necessary to mix various metal powders. Due to the characteristics of the powders, it is difficult to mix evenly. After retrieval, the authorized announcement number is CN206643351U, which discloses a powder mixing equipment for electric brush production, including installation Frame, first support rod, placement plate, frame, fi...

AI Technical Summary

Problems solved by technology

The utility model uses the material storage device to make the powder mix while feeding, so that the mixing effect is better, and then the frame is driven to move left and right by the pull wire, so that the powder is mixed more evenly, but the mixing is complicated and the mixing efficiency is low, so we A powder mixing equipment and mixing method for brush production is proposed to solve the above problems
