Description

Cavity-adjustable discharge hopper and color sorter

Technical Field

The invention belongs to the technical field of color sorting, and particularly relates to a cavity-adjustable discharge hopper and a color sorter.

Background

The color selector is equipment for automatically sorting and eliminating heterochromatic particles in the particle materials by utilizing a photoelectric detection technology according to the difference of the optical characteristics of the materials. And the materials after color sorting enter different cavities through the partition plates to finish the separation of finished products from defective products. The position and the angle of the partition plate in the discharge hopper directly influence the separation effect of the materials, if the position or the angle is not properly arranged, part of defective products doped in the finished products influence the net selection rate of the finished products, or the proportion of good materials in the defective products is increased, so that the carrying-out ratio of the defective products is influenced.

The separating baffle of the existing color sorter is usually integrally formed, and different materials are different from each other due to the characteristic difference, for example, when the quality of material particles for color sorting is large, the impact force of a spray valve on defective products is insufficient, so that the moving distance of more defective products is possibly too short, the defective products cannot successfully cross the height of the separating plate, and the defective products drop into a finished product groove, and the color sorting effect is finally influenced. In addition, the material has certain impact force in the falling process, and when some high-hardness materials are particularly sorted, the damage to the inner side wall of the box body is easily caused by long-term impact, even the box body is punctured, so that the service life of the whole machine is influenced.

The application can adjust the height of heightening and adjusting plate, and is suitable for sorting different materials. However, the angle of the partition plate in the application is relatively fixed, so that the accurate sorting of the materials is limited.

For another example, the application of the chinese patent application No. 201821046359.2 discloses an adjustable color sorting detection sorting machine, and the partition plate in this application includes vertical extension board, hang plate, vertical extension board height-adjustable, the vertical extension board top is located to the hang plate is rotatable. The height of the vertical extending plate of the separating baffle can be freely adjusted, and the inclination angle of the inclined plate can be freely adjusted. Although the division board in this application can realize the simultaneous control of height and angle, the regulation of hang plate angle needs to go on from the box is inside, needs to operate under the shut down state, need observe the adjustment effect after the start-up, leads to the regulation operation relatively troublesome. In addition, the problem that the inner wall of the box body is easily damaged due to long-term impact of materials is solved.
