Fine sorting and recycling assembly for waste plastic bottle

Abstract

The invention discloses a fine sorting and recycling assembly for a waste plastic bottle. The fine sorting and recycling assembly comprises an abnormal specification screening device, a multi-stage arranging conveyor device, an identifying and classifying device and a sorting device which are sequentially arranged front and back, wherein the abnormal specification screening device comprises a screening conveyor line used for conveying the waste plastic bottle, a screening mechanism arranged on the screening conveyor line, and an abnormal specification collecting line; the multi-stage arranging conveyor device comprises a plurality of plane arranging and conveying mechanisms connected end to end front and back; the identifying and classifying device comprises an identifying and classifying conveyor line used for conveying the waste plastic bottle, and the identifying and classifying conveyor line is provided with a line scanning infrared camera and a line scanning camera; and the sorting device comprises a sorting conveyor line used for conveying the waste plastic bottle, and a plurality of sorting stations which are arranged along the sorting conveyor line and correspond to different final classifications. The sorting and recycling assembly has the beneficial effects that the sorting and recycling efficiency and the refinement degree are improved.

Description

technical field [0001] The invention relates to a sorting and recycling assembly, in particular to a refined sorting and recycling assembly for waste plastic bottles. Background technique [0002] With the continuous strengthening of garbage classification and environmental protection awareness, governments of various countries have vigorously introduced policies and regulations on garbage classification and resource recycling, which has prompted major international and domestic brands with social influence to join in advocating the use or partial use of Recycled materials replace raw materials in the production of product packaging. Because brand owners control the quality of their own products such as safety and hygiene, they also strictly refer to the quality standards of raw materials in the selection and use of recycled materials. The original traditional plastic bottle recycling industry, due to history, market, on-site management, raw material characteristics and tech...

AI Technical Summary

Problems solved by technology

[0008] Due to the lack of automatic sorting and sorting equipment for the original bottles (not crushed), most of them use skilled workers to manually sort them based on their experience. Due to the complexity of recycling plastic bottles and the instability of manual sorting, serious quality problems are caused. , hindering 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

The industrial beverage bottle recycling spectrum automatic sorting machine currently on the market can only adapt to the color and material sorting of plastic bottles after being flattened and removed from the label, and cannot recycle the original plastic bottles of the city and the same material, different grades and different aging Degree of recycled plastic bottles for identification and sorting

[0009] Due to the traditional production method of plastic bottle recycling, it is difficult to carry out an effective inventory of the on-site goods, resulting in confusion in the accounts of recycling companies, and it is difficult to pass the review of the state's preferential tax policies for renewable resources, and there is a greater risk of tax violations
