Waste recycling industry is a promising industry in China. With the rapid increase of China's population, a large number of products are produced, resulting in more and more waste products with more and more complex types, many of which can be recycled. This design adopts STM32 MCU based on ARM architecture to realize the design of intelligent waste recycling station. This design is not only in line with the social development trend, but also the inevitable trend of sustainable development. Compared with the traditional way, it not only saves time and improves efficiency, but also conforms to the development trend of smart life, which is conducive to improving people's living standards, improving the construction of residents' infrastructure and making residents' lives more intelligent.

At present, the protective net cover of the apple suit mainly relies on manual fitting, and there is no machinery for automatically fitting the shockproof net cover for apple. In order to solve the existing mechanical defects and the demand of fruit farmers for the apple automatic set machine, combined with the actual situation, an automatic apple shockproof net set machine with a diameter of 8cm is designed. The machine is based on the PLC of Siemens series PLC-S7-200 SMART ST20 model, including bagging device, net storage device, cutting device, photoelectric sensor acquisition, electrical control, etc., and completes the function of automatically fitting apple shockproof net sleeves. After the sensor detects that the apple has reached the designated position, the bagging device operates to fit the anti-collision net sleeve, and then the electric heating wire cutting device cuts off the excess anti-collision net sleeve. This equipment can effectively save labor, reduce the burden for the aging society, and reduce production costs.
