Automatic powder screening machine

Abstract

The invention discloses an automatic powder screening machine which comprises a shell, a collecting box body for collecting powder is arranged at the bottom in the shell, a screening mechanism is arranged at the top of the collecting box body, the screening mechanism comprises two sliding rails fixed to the two sides of the interior of the shell, a moving plate is arranged between the two sliding rails in a sliding mode, moving assemblies are arranged between the moving plate and the sliding rails, an annular plate is fixedly connected to the top of the moving plate, and filtering holes are formed in the portion, on the inner side of the annular plate, of the moving plate. Powder is fed and discharged by controlling a switch valve on a discharging pipe at the bottom of a funnel, so that the powder falls into the annular plate, meanwhile, the powder is screened through filtering holes, an electric push rod is used for driving the moving plate to move between the two sliding rails, meanwhile, the annular plate is driven to move, the moving plate can be driven by the electric push rod to move horizontally, and the powder is dispersed under the action of inertia and then enters the collecting box body through the filtering holes.

Description

technical field [0001] The invention belongs to the technical field of powder sieving machines, and in particular relates to an automatic powder sieving machine. Background technique [0002] The demand for powder in the laser cladding industry is very large. Usually, the purchased powder is packed in a sealed bucket. The accumulation of the powder for a long time will make the powder stick together. When we use it, we need to sieve the powder, but manual sieving is cumbersome and difficult. It is wasteful, and if left for a long time, it will absorb moisture from the air or underground and become damp. There are also many types of powder sieving machines on the market, but most of them have single functions. Contents of the invention [0003] The purpose of the present invention is to provide an automatic powder sieving machine to solve the problem that the powder usually purchased is packed in a sealed barrel, and the powder will stick together if it accumulates for a lo...
