Background technique

At present, promoting the recycling of resources and mining "urban minerals" has become a basic national policy of national development. Among them, the construction of a recycling network is one of the important foundations for the implementation of this basic national policy. However, due to the lack of small balers with simple structure, low price and convenient use in domestic waste recycling outlets, it is difficult to compress and pack recycled waste plastics, waste rubber, waste paper, etc. at the recycling outlets. Since waste plastics, waste rubber, and waste paper are mostly items with small bulk density and large volume, the storage and transportation costs of waste products are very high, and most of the recycling sites have environmental problems such as dirty, messy, and poor. This is the current domestic waste recycling. One of the common technical bottlenecks in the industry.
