Cutter fragmentation device of plastic crushing machine

Abstract

The invention discloses a cutter fragmentation device of a plastic crushing machine. The cutter fragmentation device of the plastic crushing machine comprises a slicing knife which comprises a knife set used for crushing; the knife set is provided with a thread; a fixing disc used for fixing the knife set is arranged at the end portion of the slicing knife; a threaded ring used for fixing the fixing disc and the knife set is arranged at the end portion of the fixing disc; a rotary shaft is inserted into the fixing disc; a through hole used for being matched with the rotary shaft is arranged inside the knife set; the knife set is fixed to the rotary shaft through thread adjustment; a filter sieve used for filtering is arranged at the end portion of the slicing knife and provided with a fixed thread; a filter net is arranged inside the filtering sieve; an adjusting block used for adjusting the size of the filter net is arranged at the end portion of the filter net; a conveying groove isformed in the end portion of the filter net; and a containing box used for containing rough particles is arranged at the end portion of the conveying groove. Plastics are refined to facilitate later machining, screened rough particles do not need to be machined repeatedly, and the later machining efficiency is improved.

Description

technical field [0001] The invention relates to the processing field, in particular to a cutter shredding device of a plastic shredder. Background technique [0002] In recent years, our country has been a major country in plastics trade, far ahead of other countries. For plastic products, how to recycle them is what we need to pay attention to. For the vast and piled up "garbage", if we can turn waste into treasure, Not only is the sustainable environmental development strategy good for the environment, but it can also drive economic development. However, for the current process, the plastic particles often need to be heated up to prolong the heating time due to the large volume of plastic particles in the later stage of plastic processing, which in turn causes a waste of resources. Therefore, How to quickly cut into pieces and refine the particles is the object of research now. Many crushers on the market are simply crushed. For some plastics, the particles may be too larg...

[0002] In recent years, our country has been a major country in plastics trade, far ahead of other countries. For plastic products, how to recycle them is what we need to pay attention to. For the vast and piled up "garbage", if we can turn waste into treasure, Not only is the sustainable environmental development strategy good for the environment, but it can also drive economic development. However, for the current process, the plastic particles often need to be heated up to prolong the heating time due to the large volume of plastic particles in the later stage of plastic processing, which in turn causes a waste of resources. Therefore, How to quickly cut into pieces and refine the particles is the object of research now. Many crushers on the market are simply crushed. For some plastics, the particles may be too large, which makes post-processing difficult. So how to filter fine particles Chemical plastic is the problem that should be considered in the process now
