The near-infrared light with a wavelength from 1100nn to 1900nn has obviously different absorption and oscillation effects for different components such as chemical bonds common in plastic materials. The light reflected from different materials can form a unique spectrum, which enables the NIR spectrometer camera to be used to analyze and identify different plastic components.
01. Scope of application
Qunfeng Heavy Industry has made a revolutionary solution in the treatment of light packaging. The equipment can realize the screening of six different light materials: PET, PE, PP, beverage packaging, cardboard, and other waste
02. Workflow
For sorting the material through the feeder, uniform layout in the high-speed conveyor belt, into the light, scanning and control system, the spectrum analyzer near-infrared light to illuminate the supplies, while the spectrum of the spectrum analyzer, receiving camera accept material reflection spectrum signal, analyze the characteristic spectrum, once you discover a preset, need to separate the material, Computer control to the back of the signal control, high-pressure air injection system for the selected material with the conveyor belt to the blanking mouth, high-pressure air nozzle, change the material of the original parabolic, separation by gas injection into the material room, rather than the target material will continue to run along the direction of the original parabolic, realize the separation of materials.
03. Equipment advantages
· Fast sorting speed: scanning frequency of 500 times per second and "Free Fall" design, sorting detection position is close to the air valve mouth, avoiding time error of blowing off action, greatly increasing accuracy, and avoiding various misjudgment and related cleaning problems caused by surface pollution.
· Unique light source: focusing halogen lamp with a unique design can meet the requirements of maximum brightness and minimum energy consumption. Easy to change the design, reduce maintenance costs.
· Module seat: module seat design, can meet the needs of different sources, different aperture replacement. Valve seat removable design for different sizes of feed and belt width. Millisecond level of blowing time control greatly reduces air consumption.
· Integrated interface: systematic design with two groups of independent operation touch screens, all actions and messages clearly displayed.
· Safe and reliable: adopt the highest specification of safety components and circuit system design to ensure the safety of operation and compliance with relevant safety regulations.
