Material conveying speed control method of special material conveyer for aluminum powder

Abstract

The invention discloses a material conveying speed control method of a special material conveyor for aluminum powder. The material conveying speed control method comprises the following steps that a,a machine power source is started, a first control brake valve between a material barrel and a material conveying machine is controlled to be opened through a control button on a controller, so that the aluminum powder flows into the material conveying machine from the material barrel under the effect of the earth gravity; b, a second control brake valve at the tail portion of the material barrelis controlled to be opened through the control button on the controller, a motor is started, an original revolving speed of the motor is selected, and the motor is enabled to work according to a set revolving speed through a frequency changer; and c, the motor drives a screw conveyor shaft to rotate after being electrified, the screw conveyor shaft conveys the aluminum powder to the tail end of the material conveying machine, and the aluminum powder flows out from a discharging pipe. The material conveying speed control method has the beneficial effects that the material conveying speed of thealuminum powder is adjusted through various kinds of methods, so that the material conveyor is in a best material conveying state, and the phenomenon that materials are blocked or incomplete in the production process is avoided.

Description

technical field [0001] The invention relates to the technical field of marking machines, in particular to a method for controlling the feeding speed of a special feeder for aluminum powder. Background technique [0002] Due to its metallic luster and the characteristics of being parallel to the coated object, aluminum powder is suitable for use in transparent pigments. Aluminum powder In the carrier, the gloss and color depth of the aluminum powder change with the incident angle and viewing angle of the incident light. This characteristic is called "two-color effect". The aluminum powder is arranged in different layers in the coating film. When the incident light hits each layer of aluminum flakes, the reflected light obviously has different brightness due to the different weakening of the coating film passing through different thicknesses. When the light enters the film layer containing transparent pigment and aluminum powder, the incident light passes through the pigment ...

Problems solved by technology

Since the aluminum powder is a metal powder, the aluminum powder is not only easy to oxidize after contact with the control, but also easy to become a mixed explosive. Therefore, the transportation of the aluminum powder must be carried out in a closed container to reduce the contact with the air. During the use of the aluminum powder , The equipment for conveying aluminum powder is a special equipment. Most of the existing aluminum powder feeders cannot adjust the feeding speed, which is not suitable for use in different scenarios, and the feeder with a speed regulating device has a relatively simple way of controlling the feeding speed.
