Color sorter for sorting circular particles

Abstract

The invention relates to the technical field of sorting equipment, and discloses a color sorter for sorting circular particles. The color sorter comprises a hopper, a vibrating feeding mechanism is arranged below the hopper, and a guide mechanism is obliquely arranged below a discharge end of the vibrating feeding mechanism. According to the color sorter for sorting the circular particles, throughthe arrangement of a flow dividing mechanism, when the particles move downwards to the position between the two sets of fan blades from a gap of a rotating mechanism, after the fan blades rotate by aquarter of a circle, the particles located between the two sets of fan blades continue to fall down through the flow dividing mechanism, when the flow dividing mechanism rotates by a quarter of the circle again, a second batch of particles fall down; and in cycles, it is guaranteed that particles accumulated above can fall downwards in a single-layer, bundle-shaped and spaced mode after passing through the flow dividing mechanism and enter a sorting chamber to be subjected to color sorting, the problems that particles of a traditional color sorter are not uniform during discharging, and the screening precision is affected are solved, the working efficiency of the color sorter is improved, and the sorting precision is improved.

Description

technical field [0001] The invention relates to the technical field of sorting equipment, in particular to a color sorter for round particle sorting. Background technique [0002] The color sorter is a device that uses photoelectric technology to automatically sort out the different-color particles in the granular material according to the difference in the color of the material. Its working principle is as follows: Figure 9 Shown: The selected material enters the machine from the hopper on the top, through the vibration of the vibrator device, the selected material slides down the chute channel, accelerates and falls into the observation area of ​​the sorting room, and passes between the sensor and the background plate, and passes through the light source Under the influence of light, according to the intensity of light and color changes, the system generates an output signal to drive the spray valve to blow the different-colored particles into the waste cavity of the recei...

Problems solved by technology

[0003] However, the existing color sorters for sorting circular particles also have the following problems in actual use: first, when the particles slide down from the chute, due to the contact collision between the particles and the contact between the particles and the chute Mutual friction will lead to the generation of a large amount of dust; when the particles fall into the sorting area, due to the high-speed airflow from the nozzle, a large amount of dust will also be generated, resulting in a large dust concentration in the detection area, which is extremely unfavorable for the image sensor. The signal acquisition seriously affects the working performance of the color sorter; secondly, the traditional color sorter often uses a single cylinder for direct feeding or crawler feeding, which leads to uneven feeding of the material, and the material above the unqualified particles Qualified particles will impact unqualified particles, which reduces the separation effect of materials in the process of color selection and air jet separation, making the finished products mixed with unqualified materials. Moreover, when the chute type color sorter is performing color sorting It depends on the gravity of the particles themselves, and the falling speed is fast, so the calculation time of the processor is short, the real-time performance of spraying waste from the nozzle is poor, the color sorting accuracy is low, and it is difficult to guarantee the screening accuracy; when the crawler color sorter is working, the particles are on the track. The running speed is stable and slow. Although the material color sorting accuracy is high, the crawler type color sorter occupies a large area, consumes a lot of energy, and has low work efficiency. The guide mechanism for bundled and spaced forms is imminent
