Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of shoe sole waste recycling and processing, and specifically relates to a waste recycling and reusing device for shoe sole processing. BACKGROUND

[0002] In the production process of modern shoe-making industry, shoe sole processing is one of the core links, and the cutting and cutting process is a key step to determine the size accuracy and fit of the shoe sole. In order to adapt to the design requirements of different shoe types, enterprises usually use numerical control cutting machines, laser cutting machines and other high-precision equipment to accurately cut various shoe sole substrates such as rubber, polyurethane, EVA and TPR, so as to ensure that the profile, anti-skid lines and shock-absorbing structure of the shoe sole meet the product standards. However, a large amount of waste will inevitably be generated in this process, including substrate scraps, cutting debris and unqualified semi-finished products. If such waste is discarded at will, not only will it occupy a large amount of storage and landfill space, but the chemical components contained therein may also seep into the soil and pollute water sources, causing potential harm to the ecological environment. At the same time, the shoe sole raw materials are mostly non-renewable resources, and the waste of waste also means a decrease in resource utilization. Therefore, the shoe-making industry generally attaches great importance to waste recycling and processing, and through classification collection, crushing and grinding, high-temperature melting and other processes, waste is converted into renewable raw materials and reused for the production of shoe sole substrates or the processing of other industrial products. This measure not only effectively reduces environmental pollution and reduces the raw material procurement cost of enterprises, but also meets the development concept of circular economy and green production, becoming an important support for the sustainable development of modern shoe-making industry.

One end of the rotating wheel two extends out of the cutting chamber and is fixedly connected with a gear two. The gear one and the gear two are engaged. The application drives the rotating wheels one and two to rotate by a motor one, cuts the shoe sole waste, preheats the waste particles by a heating plate to soften them, and finally drives the pressing rollers one and two to rotate by a motor two to extrude the waste particles into waste boards, thereby reducing resource waste and environmental pollution.
