Sorting box sealing device and structure

Abstract

The invention belongs to the technical field of mechanical sealing of sorting machines, and in particular relates to a sorting box sealing device and structure. The sorting box sealing device comprises a clamping part and an elastic sealing part, wherein a metal framework is embedded into the clamping part; the clamping part can be mounted at a strip-shaped plate which is arranged at the side edge of an opening part of a sorting box body or at the side edge of a sorting box door in a convex extending manner; the elastic sealing part equipped with an empty cavity part is connected to the outer wall of the clamping part; an air hole for communicating the empty cavity part and the outer part is formed in the elastic sealing part; when the sorting box door is closed, the outer wall of the sorting box body or the inner wall of the sorting box door can press the elastic sealing part, so that the elastic sealing part can be closely matched with the outer wall of the sorting box body or the inner wall of the sorting box door. The sorting box sealing device is applicable to a sorting machine, and can effectively prevent dust, mist and the like from entering the sorting box body, so that the sorting stability of the sorting machine can be effectively improved; meanwhile, the sorting box sealing device is simple in structure, and low in cost, and has a good popularization prospect.

Description

technical field [0001] The invention belongs to the technical field of mechanical seals of sorting machines, in particular to a sorting box sealing device and a sorting box sealing structure. Background technique [0002] The working principle of the sorting machine is that the selected materials are transported to the sorting area by the feeding system through a narrow and long transmission chute or belt. The sorting area is equipped with two sets of high-stable light sources and high-sensitivity photoelectric sensors. The high-stable The light source and photoelectric detector are in a sealed environment. When the material flows through the sorting area, the light source irradiates the material through the transparent glass window, and the reflected light of the material and the reference light enter the photoelectric sensor through the transparent glass window, and the sensor reflects the material The light is compared with the reference light, and the color difference be...

AI Technical Summary

Problems solved by technology

[0003] Since the selected raw materials contain a lot of dust or the raw materials themselves are water-carrying materials, these raw materials will generate a lot of dust or water vapor after being transported through a narrow and long transmission chute or a belt. If the sealing of the sorting box is not strong, these will be It will have a great impact on the highly stable light source and photodetector. Dust or mist will adhere to the lens and light source, which will cause a large error in the identification of the raw material by the photodetector, and some dust will enter the sorting box After being disassembled, it will seriously affect the service life of electrical components, thus affecting the stability of the whole machine
