Automatic color sorting system and method for plastic bottles

Abstract

The invention relates to an automatic color sorting system and method for plastic bottles. The technical problems of unreasonable design and the like in the prior art are solved. The system comprisesan annular conveying mechanism and a vibration hopper; a discharge port of the vibration hopper is connected with one end of an annular conveying belt through a conveying inclined plate; a dark box with an inner cavity is arranged above the end, close to the vibration hopper, of the annular conveying belt. A color recognition device is arranged in the dark box, a plurality of pneumatic separationmechanisms are sequentially arranged at the end, away from the dark box, of the annular conveying belt; the pneumatic separation mechanisms are sequentially distributed along the annular conveying belt, and the pneumatic separation mechanisms are connected with the color recognition device. The automatic color sorting system has the advantages that an annular light source provides a constant lightsource, external interference is reduced, and sorting accuracy is improved; an industrial camera is matched with an upper computer to finish classification of colors and categories of the plastic bottles, and high-pressure pneumatic nozzles perform pneumatic separation on the identified plastic bottles, so that the plastic bottles are collected according to categories, and the sorting efficiencyis high.

Description

technical field [0001] The invention belongs to the technical field of sorting equipment, and in particular relates to an automatic color sorting system and method for plastic bottles. Background technique [0002] With the development of industry, the application of plastic products has spread all over the fields of industry, agriculture and daily life. The waste plastic waste generated every day in the world cannot be estimated, but it is obvious that it has a great pressure on the environment. In order to deal with these plastics Garbage, the current methods are generally landfill, incineration, etc., but these disposal methods will have a greater impact on the environment. With the continuous improvement of environmental protection awareness, most plastic products will be recycled and reused. For example, at present, portable beverages such as bottled mineral water are more and more popular due to their characteristics such as easy to carry, clean and hygienic, and a la...

Problems solved by technology

[0004] Although the above scheme has solved the problem of low efficiency of manual sorting of plastic bottles to a certain extent, there are still some problems in this scheme: the sorting effect is poor, and the sorting speed is still not ideal.
