With the continuous development of the urban industrialized era, the invention of the disposable beverage bottle brings great convenience to the life of people. The environmental pollution problem is also getting worse, and a large number of waste beverage bottles can be seen everywhere in various public places, thereby influencing the natural ecological environment. From the perspective of saving resources, as the main source of plastic products is petroleum resources facing exhaustion, increasingly increasing domestic garbage and environmental pollution are gradually the outstanding contradictions of society as far as possible, and although the government of China has issued some relevant policies, the domestic garbage is difficult to form a standard management system and the citizens are lack of environmental awareness, so that the recovery rate of recoverable garbage in life is very low, and most beverage bottles are abandoned in vain without classification after being drunk by people. Therefore, the recovery rate of the plastic bottles in China is not high, the plastic wastes generated in our country every year are nearly 3000 ten thousand tons, and the recovery rate is partially buried and burned. Not only wastes resources, but also pollutes the environment.

Digital image processing has been a subject since the 60's 20 th century. The purpose of early image processing was to improve the quality of images, which were targeted at human subjects with the goal of improving human visual effects. Later, with the continuous development of computer application science and artificial intelligence technology, image recognition technology is developed. Image recognition technology was first applied in the united states in the fields of military, space satellite, etc. With the rapid development of automation, big data and internet of things technologies, image recognition technologies are increasingly popularized to the civil aspects such as medical health, face recognition, intelligent navigation and the like. This provides the present project with a sufficient theoretical basis for sufficient image recognition processing.

After the extruded and cut plastic bottles are collected subsequently, the labels can be separated from the plastic bottles by matching with a fan and a vibrating screen because the density of the labels is lower than that of the plastic bottles. It is understood that a fan (not shown) is provided in the housing 4, the output 52 of which is located above the third plate 19, and the fan is capable of separating the cut labels with a lower density from the plastic bottles after the lever 35 has initially blocked the compressed and cut plastic bottles. Further, a separating plate (not shown) is arranged in the box body 5 along the axial direction of the shell 4, the separating plate divides the box body 5 into a first part and a second part, the first part far away from the fan is used for collecting labels, and the second part close to the fan is used for collecting plastic bottles. The bottom end of the box body 5 is also provided with an output port 52, and the output port 52 is communicated with the pipeline 8.

The controller 23 activates the electromagnet 37 corresponding to the sorting unit 21 according to the sorted result, and when the electromagnet 37 is energized, a magnetic force larger than the spring 39 is generated, so that the second link 292 and the first link 291 connected to the second link 292 rotate, the first link 291 moves from the diagonal position of the third through hole 211 to the long side of the third through hole 211, and the third through hole 211 corresponding to the type of the plastic bottle is opened. Then the controller 23 starts the first motor 10, and after the first motor 10 drives the first gear 26 to rotate, because the first gear 26 is meshed with the rack 27, the slide member 32 connected with the rack 27 can be driven to move, and the push plate 12 connected with the slide member 32 pushes the topmost plastic bottle in the moving member 6 to move.

It should be noted that, because the plastic bottles are transversely stacked, after the topmost plastic bottle is identified and classified according to the above method, the air cylinder 9 drives the connecting rod 34 to move downwards, so as to identify and classify the next layer of plastic bottles, and further identify, classify and collect the plastic bottles layer by layer.

According to the invention, the plastic bottle identification part 33 is used for carrying out image identification and classification on the plastic bottles, the electromagnet 37 corresponding to the classification part 21 is started according to the classification result, and the electromagnet 37 generates a magnetic force larger than that of the spring 39 after being electrified, so that the rod body 29 rotates, the third through hole 211 corresponding to the class of the plastic bottles is opened, when the plastic bottles slide along the inclined plane 212, the plastic bottles can fall into the third through hole 211 opened after the rod body 29 rotates for collection, different types of waste plastic bottles can be respectively collected and processed, the workload of subsequent processing is reduced, and the processing efficiency of the waste plastic bottles is improved.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
