Background

The color sorter is used as material sorting equipment with excellent performance and is widely applied to industries of food processing, ore sorting, plastic sorting and the like. The basic working principle is as follows: according to the difference of the optical characteristics of the materials, the different-color particles in the particle materials are automatically sorted out by utilizing a photoelectric detection technology. The materials are conveyed to the collecting hopper through the hoister, and are dispersed to the channels through vibration of the vibrator. The materials with different qualities need to pass through different material distribution channels, and the partition plates are arranged among the different material distribution channels to prevent the falling paths of the materials with different qualities from being overlapped.

At present, granular materials are conveyed into a collecting hopper through a lifting machine, and because the granular materials have certain flowability, the materials can flow and disperse to outlets of all vibration channels through the materials, so that the feeding requirement of all channels is met, and the yield is ensured. However, the color sorter needs to sort various materials, materials of different shapes or materials of different sizes are sorted, for example, flaky plastic is sorted, the flaky plastic is easy to generate static electricity for material superposition, the elevator conveys the materials to the collecting hopper, the materials are discharged through one outlet or a plurality of outlets, the materials are difficult to uniformly disperse to the outlets of all channels, few or even no materials exist at the outlets of the channels far away from the elevator, so that excessive materials at partial channel openings are caused, the sorting effect of the color sorter is influenced, and the capacity of the color sorter is reduced.

In the existing structure, the material directly falls to the collecting hopper body inside through the lifting machine, and the material that the exit corresponds can satisfy the material demand that closes on the passway, but can not satisfy and keep away from the demand of lifting machine exit passway to the material, has influenced the output of look selection machine, is difficult to carry out even branch material and stone to the material.
