After the same batch of plastic particles is made, the baffle that closes the second opening is opened and the plastic particles in the collection chamber 112 are removed.
The cutting device for plastic particle processing provided in another embodiment of the present application is different from the above embodiment in that: the transfer wheel does not have a function of transferring the plastic wire 600 into the installation cavity 111, and in an initial state, a worker inserts one end of the plastic wire 600 between the first blade 211 and the second blade 221, and when the first driving shaft 230 and the second driving shaft 240 rotate, the first blade 211 and the second blade 221 stir the plastic wire 600 into the installation cavity 111.
