Embodiment 1

[0027] refer to figure 1 , figure 2 , image 3 The mixed plastics infrared identification and sorting equipment of the present embodiment includes a conveying mechanism 1, a feed control tank 2, an infrared identifying device 3, and a blowing device 4. The conveying mechanism 1 can be a conveyor belt, and its working surface is 10 to the horizontal plane. ° of inclination. According to different plastic types and sizes, the angle between the working surface of the conveying mechanism 1 and the horizontal plane can be adjusted within the range of [-15°-15°].

[0028] The feed control tank 2 is located at the beginning of the conveying mechanism 1, the feed control tank 2 has a plurality of feed ports with different sizes, the feed control tank 2 includes a feed port size adjustment mechanism, and the feed port Size adjustment mechanism is made up of fixed baffle 2-1, movable baffle 2-2, adjustment guide plate 2-3, fastening screw 2-4, nut 2-5, and described fixed baffle 2-1...

Embodiment 2

[0035] refer to Figure 4 The difference between the infrared identification and sorting equipment for mixed plastics in this embodiment and the first embodiment is that the conveying mechanism 1 is a plurality of conveyor belts arranged in parallel, or a conveyor belt with multiple intervals, and the infrared identification device 3 It has multiple sets of infrared signal emitting sensors and infrared signal receiving sensors. The purpose of such setting is that the mixed plastics of various sizes screened by the sorting sieve can be sent to the conveying mechanism 1 at the same time, and the corresponding infrared sensors can collect data sequentially. This can greatly improve the efficiency of sorting.

Abstract

The invention provides infrared recognizing and sorting equipment for mixed plastic. The infrared recognizing and sorting equipment comprises a conveying mechanism, an infrared recognizing device and a blowing device. The infrared recognizing device is located above the conveying mechanism. The blowing device is located at the tail end of the conveying mechanism. The equipment further comprises a feeding control trough. The feeding control trough is located at the initial end of the conveying mechanism and provided with a plurality of feeding openings different in size. The feeding control trough comprises a feeding opening size adjusting mechanism. The feeding control trough with the sizes of the feeding openings capable of being adjusted is additionally mounted, the mixed plastic different in size is conveyed into the conveying mechanism, blocking of the large mixed plastic is avoided, and the sorting error rate is lowered. According to the different sizes of the mixed plastic, the sizes of the feeding openings of the feeding control trough can be adjusted, flexibility and controllability are achieved, and the application range is wider. According to the different sizes of the mixed plastic, intermediate pressure of compressed air of the blowing device is adjusted, and energy-saving optimal control is achieved.

Description

technical field [0001] The invention relates to the technical field of classification of mixed plastics in the process of material recycling, in particular to infrared identification and sorting equipment for mixed plastics. Background technique [0002] With the development of chemical technology, the production and consumption of plastics are also increasing year by year. If calculated by volume, it is close to or exceeds the world's steel production. Due to the ease of processing and diversification of properties, plastics have been widely used in the fields of electronic appliances, packaging, building materials, agriculture, transportation, stationery and other fields, and have promoted the development and progress of related science and technology. According to the analysis of the production and sales of home appliances in my country, plastics for home appliances account for about 10-20% of the annual consumption of plastics. Due to different types of products, the pr...
