Embodiment Construction

[0021] Hereinafter, a PET photoelectric separation device according to an embodiment of the present invention will be described in detail with reference to the drawings.

[0022] figure 1 It is a schematic diagram of a PET photoelectric separation device according to an embodiment of the present invention. Such as figure 1 As shown, it includes feeding platform 1, feeding bin 2, vibrating feeder 3, photoelectric identification head 4, PET single-color bin 5, variegated bin 6, photoelectric identification controller 7, compressed air nozzle 8 and other main equipment.

[0023] The vibration feeder 3 adjusts the fragments into a uniform state, falls along the vertical trough, and enters the compressed air nozzle 8 area through the photoelectric identification head 4;

[0024] The sensor of the photoelectric recognition head 4 automatically recognizes fragments of different colors in the PET raw material, and the recognition result is transmitted to the photoelectric recognitio...

Abstract

The invention discloses a photoelectric PET (polyethylene terephthalate) sorting device. The photoelectric PET sorting device is characterized by mainly comprising a loading platform, a feeding chamber, a vibration feeder, a photoelectric sorting machine, a PET single-color chamber and a mixed-color chamber, wherein the photoelectric sorting machine consists of a photoelectric identification sensor, a photoelectric identification controller and a pneumatic sorting machine; the photoelectric identification sensor is used for automatically identifying fragments with different colors in PET raw materials and transmitting an identification result to the photoelectric identification controller; the photoelectric identification controller is used for controlling the pneumatic sorting machine according to settings and separating fragments with the needed color from fragments with other colors. According to the structure of the photoelectric PET sorting device, the photoelectric PET sorting device can be embedded into a PET recovery production line to automatically sort out the raw materials with the needed color, so that the aim of quality control is achieved, and the market competitiveness of an enterprise is effectively improved.

Description

technical field [0001] The invention relates to a sorting device, in particular to sorting variegated flakes from PET raw materials. Background technique [0002] Polyethylene terephthalate (PET) is a synthetic material that has been widely developed since the second half of the 1960s. The product variety of PET has expanded from the initial polyester staple fiber to polyester staple fiber, polyester filament, polyester Ester bottles, polyester films, non-woven fabrics, engineering plastics and composite multi-functional products, etc., have hundreds of products and thousands of specifications. Due to the continuous increase of social demand, the production of PET polyester has grown rapidly. my country's PET production capacity has exceeded 20 million tons in 2008, becoming the world's largest producer and consumer of PET. [0003] PET products are mostly disposable consumer goods, followed by a large amount of waste PET materials. Waste PET materials are chemically ine...
