Recovery plastic bottle identification system

Abstract

The invention discloses a recovery plastic bottle identification system, and belongs to the technical field of plastic bottle recovery treatment. The system comprises a conveying line, a foreign matter detection module, an information identification module, an aging detection module, an AI identification module and a material identification module which are arranged on the conveying line, and an identification analysis module arranged at a control end, wherein the identification analysis module is used for receiving an infrared transmission image acquired by the foreign matter detection module, one-dimensional code information recognized by the information recognition module, an ultraviolet fluorescence image acquired by the aging detection module and a spectral image recognized by the material identification module; and the identification analysis module identifies whether foreign matters exist in the plastic bottles, the aging degree of the plastic bottles, the material types of the plastic bottles, the information of the plastic bottles and the AI identification information, and performs classification operation based on an identification result. According to the invention, the plastic bottles with foreign matters, different brands, different materials, different aging degrees and different types are finely identified and classified, and the intelligent identification is accurate and efficient.

Description

technical field [0001] The invention relates to the technical field of recycling plastic bottles, in particular to an identification system for recycled plastic bottles. Background technique [0002] The original traditional plastic bottle recycling industry, due to history, market, on-site management, raw material characteristics and technical reasons, is mostly designed with the idea of ​​reducing costs. Most of the employees and enterprises are individuals, individual industrial and commercial households and small and micro enterprises. , Most of them use the weighbridge to carry out simple physical weighing of incoming materials, and rely on manual experience to carry out simple material classification and color classification accounting for plastic bottle recycling, and use simple mechanical transmission and compression equipment to carry out classification compression packaging operations. For this reason, there are the following problems: 1. Due to the residues of rec...

AI Technical Summary

Problems solved by technology

For this reason, there are the following problems: 1. Due to the residues of recycled plastic bottles, and a large amount of sundries in the recycling process, the diversity and complexity of packaging materials and other factors, in the recycling process, due to the lack of uniform Standards and reasonable inspection methods, resulting in difficult pricing and many disputes

2. At present, most of them rely on semi-mechanized conveyor belts, balers and other equipment for manual packaging operations, and the operation yard is large, resulting in an increase in transportation and recycling costs.

In addition, there are many types of recycled plastic bottles, complex materials, large volume, many plastics, and light weight (about 40,000 beverage bottles per ton), which makes the job site chaotic, and the garbage and residues caused by each of them cause odor and The noise of equipment has brought major hidden dangers to the safety of workers and environmental protection on site

3. Due to the lack of automatic sorting equipment for the original bottles (not crushed), most of them use skilled workers to manually sort them based on their experience; also because of the complexity of recycling plastic bottles and the instability of manual sorting, serious Hidden quality hazards hinder the development of high-quality utilization of downstream production enterprises

In particular, food grade and non-food grade cannot be effectively distinguished, which will pose a huge obstacle to China's future policy of using recycled plastics for food packaging

4 Due to the traditional production method of plastic bottle recycling, it is difficult to carry out an effective inventory of on-site goods, resulting in confusion in the accounts of recycling companies, and it is difficult to pass the review of the state's tax preferential policies for renewable resources, and the risk of tax violations is relatively high

This invention cannot finely identify and classify plastic bottles with foreign objects, different brands, different materials, different aging degrees, and different types, and the level of intelligent classification is inefficient
