Plastic bottle classifying and recycling device based on light element composition principle

Abstract

The invention relates to the technical field of plastic recycling and classifying equipment and discloses a plastic bottle classifying and recycling device based on the light element composition principle. The plastic bottle classifying and recycling device comprises a conveying belt. A lamp source is connected to the upper end of the interior of a shell. A detecting device is connected to the middle portion of a transverse plate. A column-shaped groove is formed in the upper end of the detecting device in a surrounding manner. An optical filter is connected to the upper end of the detecting device. A light-emitting diode is connected to the upper end of the detecting device. A control module is connected to the lower side of the interior of the detecting device. According to the plastic bottle classifying and recycling device, light passes through the optical filter in the column-shaped groove formed in the detecting device, the light-emitting diode converts a light signal into an electric signal and transmits the electric signal into the control module, the size of the electric signal generated by the light-emitting diode can be indirectly considered as the proportion occupied bycomposition of three kinds of light, thus colors of bottles can be judged indirectly, and the structure solves the problem that an existing plastic bottle sorting device cannot be applicable to plastic bottles with different thicknesses and shades.

Description

technical field [0001] The invention relates to the technical field of plastic recycling and sorting equipment, in particular to a sorting and recycling device for plastic bottles based on the composition principle of light elements. Background technique [0002] Plastic bottles are made of materials such as polyethylene or polypropylene, and are made after adding a variety of organic solvents. Plastic bottles generally use polyester, polyethylene, and polypropylene as raw materials. After adding corresponding organic solvents, they are heated at high temperatures and blow-molded, extruded, or injection-molded plastic containers through plastic molds. It is mainly used for liquid or solid disposable plastic packaging containers for beverages, food, pickles, honey, dried fruits, edible oil, agricultural and veterinary drugs, etc. Plastic bottles are not easy to break, low in cost and high in transparency. [0003] At present, due to our country's great emphasis on the enviro...
