The utility model belongs to the technical field of
plastic bottle production
raw material pretreatment, and particularly relates to a plastic particle
drying device for
plastic bottle production, which comprises a screw conveyer, the screw conveyer comprises a casing, a driving mechanism is arranged at one end of the casing, a screw shaft is rotatably arranged in the casing, and the top surface of the casing is opened. The top face of the end, close to the driving mechanism, of the
machine shell is provided with a feeding port, the end, away from the driving mechanism, of the
machine shell is provided with a discharging port, the
machine shell is sleeved with a heating jacket, the top face of the machine shell is provided with a cover plate, the top of the cover plate is provided with a hot
air channel, one end of the hot
air channel communicates with the feeding port, and a filtering plate is arranged between the hot
air channel and the machine shell. An auxiliary material adding box is arranged above the end, close to the feeding port, of the hot air channel. The plastic particle
drying device solves the problem that plastic particles fall between the conveying belt and the inner wall of the
drying cylinder in the conveying process to cause material leakage, the plastic particle drying efficiency is improved, and follow-up production is facilitated.
