Abstract

The invention discloses a plastic particle screening device. The plastic particle screening device comprises a screening barrel, sieve plates and a rack. The sieve plates are arranged in the screeningbarrel. Valves are arranged on the side wall and the bottom of the screening barrel. A vibration mechanism is arranged at the bottom of the screening barrel and comprises a connecting rod, a crank and a motor. The connecting rod is hinged to the bottom of the screening barrel, one end of the crank is hinged to the connecting rod, and the other end of the crank is connected with the motor fixed tothe rack. An air supply system comprises installing bases and air cylinders, the installing bases are fixedly arranged at the bottom of the screening barrel, and a piston rod is arranged between eachinstalling base and a piston of the corresponding air cylinder. The side wall between the bottom of each air cylinder and the corresponding piston is provided with an air inlet one-way valve and an air outlet one-way valve. An air inlet is formed in the side wall of the screening barrel, and a ventilation pipe is connected between the air inlet and each air outlet one-way valve. By adoption of the scheme, damage to a screening barrel body is little, and large plastic particles blocking sieve holes are more easily separated from the sieve plates.

Description

technical field [0001] The invention belongs to the technical field of plastic manufacturing and processing, and in particular relates to a plastic granule screening device. Background technique [0002] The pelletizing part in the extrusion granulator is the main device in the auxiliary equipment of the extrusion pelletizing equipment. The pelletizing auxiliary equipment is divided into two types: hot cutting and cold cutting according to its working mode and function, and the hot cutting is mostly air-cooled. Pelletizing is carried out in a hot-cutting way. The air-cooled hot-cutting extruder includes a screw, a barrel, a perforated plate, a splitter cone, a strip-shaped material forming template, and a slicing knife. The formula is metered and compounded, added to the high-speed mixer and stirred evenly, then put into the barrel of the extruder granulator, plasticized and melted into a viscous fluid state, extruded from the perforated plate in front of the barrel into str...
