Colour selector

Abstract

The invention discloses a colour selector. The colour selector comprises a feeding hopper, a sliding way, sorting devices and material receiving devices; a vibrating plate is arranged below the feeding hopper; the sliding way is formed in one side of the vibrating plate and extends downwards to the position between the two sorting devices; the material receiving devices are arranged below the sorting devices; each sorting device comprises a light source radiating device and a sight glass adjusting device; each light source radiating device comprises a lamp holder and fans; the lamp holder is a hollow tubular lamp holder; an LED (Light-Emitting Diode) lamp panel is arranged on the side of the lamp holder; the fans are arranged at the two ends of the lamp holder; each sight glass adjusting device comprises a sight glass beam, a sight glass frame and a mounting bottom plate; a camera plate is mounted at the front end of the mounting bottom plate; the sight glass transversely penetrates through the mounting bottom plate and the sight glass frame; each material receiving device comprises a front material receiving hopper and a rear material receiving hopper; each rear material receiving hopper comprises side plates and a rear baffle plate; the rear baffle plate is a movable overturning plate; and a material outlet is formed at the joint of the two side plates and the lower end of the movable overturning plate. The colour selector has the advantages that the sight glass can be adjusted precisely at a plurality of angles, a spraying valve can be maintained quickly, and temperature dissipation of light source equipment can be accelerated.

Description

technical field [0001] The invention relates to the technical field of color sorters, in particular to a color sorter. Background technique [0002] The color sorter is a device that uses photoelectric detection technology to automatically sort out the different-color particles in the granular material according to the difference in the optical characteristics of the material. It is widely used in food, medicine, and other industrial production fields. Specifically, the material is transported from the feeding hopper, vibrator, and slide to the sorting area. There are high-stable light sources and high-sensitivity photodetectors before and after the sorting area. The high-stable light source and photodetectors need to be in a sealed separation area. In the selection box, when the material flows through the sorting area, the light source and the photodetector compare the light signal of the reflected light and the transmitted light of the material detected with the reference...

Problems solved by technology

However, (1) the structure of the mirror adjustment device of the traditional color sorter is complex, and it cannot be easily and quickly realized its multi-angle precise adjustment; (2) the maintenance of the spray valve assembly in the traditional color sorter is very troublesome, and it needs to be The external structures are disassembled one by one, involving the disassembly and assembly of a large number of fasteners, which is time-consuming and labor-intensive; even if the disassembly starts from the rear connection hopper adjacent to the spray valve assembly, due to the non-detachable structure adopted by the traditional rear connection hopper or Removable installation through a large number of fasteners is still time-consuming and labor-intensive

[0004] In addition, during the operation of the color sorter, the high-stable light source is in a state of light and heat for a long time, and the heat around it continues to accumulate and the temperature continues to rise; after long-term development, the service life of the light source equipment will be greatly reduced; many other around the high-stable light source The working device is also very easy to cause operation errors due to excessive temperature, which further affects the operation of the entire color sorter device, resulting in misjudgment of color sorting and affecting the accuracy of color sorting

At present, there is no simple and efficient heat dissipation device specially designed to meet the heat dissipation requirements of the light source equipment of the color sorter
