Small powder proportioning device

Abstract

The invention provides a small powder proportioning device, which comprises a proportioning barrel and a plurality of material boxes filled with different powders, and also comprises a rotating disc, the material boxes are uniformly separated and fixed around the circumference of the rotating disc, the bottom of the rotating disc is connected with a main motor for driving, and the main motor is electrically connected with a control host; a discharge port is formed in the lower end of the material box, and an electromagnetic valve is mounted at the discharge port; a material receiving barrel is arranged below the rotating disc, when one material box rotates to the position above the material receiving barrel, the discharge port is aligned with the material receiving barrel, and a weighing sensor is arranged at the lower end of the material receiving barrel. A material suction pipe is arranged beside the material receiving barrel, the material suction pipe is connected with a material suction machine, the other end of the material suction machine is sequentially connected with a first material conveying pipe and a second material conveying pipe, and one end of the second material conveying pipe is communicated with the proportioning barrel; a piston is arranged in the second conveying pipe, a reciprocating telescopic air cylinder is fixed to one end of the piston, an inflation leather bag is fixedly sleeved with the middle of the piston, cleaning bristles are arranged on the surface of the inflation leather bag, and the inflation leather bag is controlled by an air pump to contract and expand. According to the invention, the residual powder adhered to the pipe wall is reduced, the component content error after proportioning is reduced, and the qualified rate of product proportioning automation is improved.

Description

technical field [0001] The invention relates to the technical field of batching equipment, in particular to a small-scale powder proportioning device. Background technique [0002] Batching refers to the process of mixing certain raw materials together in a certain proportion during production, which is a common process step in industrial production. However, in the process of automatic feeding and pipeline feeding of the powder batching device, the long feeding pipeline and pipeline route structure make it easy for the remaining powder in the tube wall to not all enter the batching tank, which is different from the actual situation. There is a deviation in the weighed powder, which causes the proportion of the finished product after the final mixing ratio to fail to meet the requirements, there is a large error, and the quality is unqualified. Contents of the invention [0003] The purpose of the present invention is to provide a small powder proportioning device capable...
