Sorting machine discharge port for preventing material residues and dust from accumulating

Abstract

The invention discloses a sorting machine discharge port for preventing material residues and dust from accumulating. The sorting machine discharge port is characterized in that a wall surface of the discharge port is designed to be a net-shaped or grid type structure, mesh shape and size are set according to material size, the material residues and the dust can be discharge together with a material from a discharge port material outlet (2), and a great deal of material residues and the dust are prevented from accumulating on the surface of a background plate. The sorting machine discharge port provided by the invention has the advantages that since the net-shaped or grid type wall surface is adopted, the problem that a great deal of material residues and dust are accumulated due to unsmooth air current circulation at a material outlet is solved, the continuous operation time of a sorting machine is greatly prolonged, and the operation efficiency of the sorting machine is improved.

Description

technical field [0001] The invention relates to the technical field of material sorting machines, in particular to a sorting machine outlet for preventing material residues and dust from accumulating. Background technique [0002] Already know the working process of the material sorting machine, see figure 1 As shown: the material W enters the sorting machine from the feeding hopper 1, and is transported to the detection area through the chute 2 and the belt conveyor 3 in sequence. The detection area is composed of a background plate 4, a background light source 5 and a camera 6. The light shines on the material through the background plate 4, the purpose is to make the characteristics of the material in the background more obvious, and then the image is taken by the camera for detection and classification. After the classification is confirmed, the pneumatic spray valve 7 is instructed to change the jet flow of a certain type of material Its running trajectory, so differen...

Problems solved by technology

[0007] However, this improvement has the following disadvantages. The size of the dug hole is limited by the size of the walls on both sides of the outlet, which is not enough to meet the requirements for dredging the air flow. In addition, because the air is drawn from the inside to the outside of the outlet, it is often impossible to pass through the hole. The residue or material of the filter screen is adsorbed on the filter screen, which can neither fall nor be sucked out, resulting in the blockage of the suction hole, which cannot play the role of dredging the air flow, and the above-mentioned material residue and dust accumulation will occur. The operation still needs to stop at regular intervals to clean the filter screen and accumulation

Another disadvantage of this improvement is that additional equipment is added to the sorting machine, and different power suction equipment is required for the sorting of different materials, which greatly increases the cost of research and development, production and maintenance of the machine
