Uniform material distribution apparatus of color sorter

Abstract

The present invention discloses a uniform material distribution apparatus of a color sorter. The apparatus is characterized in that: a material distribution plate with an umbrella-shaped surface is arranged on the material falling path of a material outlet of a lifter; the material distribution plate with the umbrella-shaped surface is adopted as a supporting surface for the falling material from the material outlet of the lifter; the falling material falls in a vibration hopper arranged below the material distribution plate with the umbrella-shaped surface by the umbrella-shaped distribution of the material distribution plate with the umbrella-shaped surface. With the present invention, the influence on the color sorting effect due to non-uniform material falling during the color sorting process can be effectively solved, the color sorting efficiency and the color sorting effect are improved.

Description

technical field [0001] The invention relates to a solid material uniform distribution device, in particular to a color sorter material uniform distribution device. Background technique [0002] The working principle of the color sorter is that the selected material is transported to the sorting area by the feeding system, and the sorting area is equipped with a light source and a photodetector. When the material flows through the sorting area, the light source and photodetector will detect the The amount of reflected light and transmitted light of the material is compared with the reference light amount, and the color difference between the selected material and the reference color is used to identify the heterochromatic particles, and the heterochromatic particles are removed by the air injection system. When the material to be selected passes through the sorting area, if the material distribution is uneven and there is overlap, it will affect the detection effect of the ph...

Problems solved by technology

Because the tea leaves are piled up in the middle of the elevator, most of the tea leaves falling on the vibrating hopper are concentrated in the trough in the middle of the vibrating hopper, and there are relatively few tea leaves in the troughs on both sides, which affects the uniformity of feeding

The accumulated tea leaves block each other, which greatly affects the accuracy of tea color sorting

[0004] For the above problems, there are currently two solutions: the first method is to scatter the tea evenly into the vibrating hopper manually, but this method is inefficient and is easily affected by the operating level of the employees. In addition, the operators are not only affected by the noise Hazardous, and there is a safety hazard in standing at a high place to fabricate

The second method is to use a hoist to lift the material to a higher height and then automatically drop it into the vibrating hopper. Although this method avoids the danger of manual operation, it also improves the accumulation of materials to a certain extent. There are still a large number of phenomena, and the color selection effect has not been well resolved
