The invention discloses a squeezing pre-grain-
cutting machine for plastic
recovery. The squeezing pre-grain-
cutting machine comprises a rack, a squeezing
barrel, a heating and cooling device and a pre-grain-
cutting device, wherein an upstream bearing pedestal and a downstream decompression seal are arranged on the rack, two ends of the squeezing
barrel are fixed between the upstream bearing pedestal and the downstream decompression seal, a feeding hole is formed in the squeezing
barrel, an extruding screw rod is arranged between the upstream bearing pedestal and the downstream decompression seal, the extruding screw rod is positioned in the squeezing barrel and is connected with a screw rod power device, the heating and cooling device is arranged at the downstream of the squeezing barrel, a
water filter hole is formed in the upstream section of a squeezing barrel body, a
discharge hole is also formed in the downstream section of the squeezing barrel body, a downstream decompression sealing base comprises a decompression sealing barrel and a sealing bearing pedestal, the decompression sealing barrel stretches into the downstream opening of the squeezing barrel, an
optical axis part is arranged at the downstream of the extruding screw rod, the
optical axis part is arranged in the decompression sealing barrel to be in clearance fit with the decompression sealing barrel, the pre-grain-cutting device is arranged on the rack and is located at the downstream end of the squeezing barrel, and the pre-grain-cutting device comprises a grain cutter and a grain cutter power device. The squeezing pre-grain-cutting
machine has high working efficiency and long service life.
