The working process and principle of the invention are as follows:
the material is put into to first feed inlet 11 of vibration chute 10 upper end, starts vibrating motor 17, and vibration chute 10 vibrates from top to bottom under vibrating motor 17's effect, and the material disperses gradually on vibration chute 10, and when the material was through suction hood 14, the less slice material of size was siphoned away by suction hood 14, and the less granule material of size falls into slag discharging channel 18 from orifice plate 13, later discharges through bottom lower extreme slag discharging port 19. The material gradually falls from the first discharge port 12 and flows into the spiral blade 28 in the spiral cylinder 21 through the second feed port 212. The wind of the first fan 23 is strengthened by the first transition joint 221 and then blows into the helical blade 28 in the helical cylinder 21, the materials spirally ascend on the helical blade 28 under the action of the wind power, lighter label paper fragments fly out from the third discharge port 213 at the top end of the helical cylinder 21, and heavier bottle body fragments fall into the channel 29 in the process of moving upwards through the helical blade 28, so that the heavier bottle body fragments fall into the material distribution box 26. The material does a parabolic motion under the action of the wind of the second fan 25, lighter label paper fragments fly through the filter screen 27 and fly out of the material distribution box 26, and heavier bottle body fragments fall into the material distribution box 26 under the action of gravity. The fragments of various types are collected in a classified mode, the filter screen 27 is opened, and the fragments in the distribution box 26 are collected.
