Discharging structure of plastic extruder

Abstract

The invention belongs to the field of plastic processing, and particularly relates to a discharging structure of a plastic extruder. For solving the problem that a corresponding screening device is not arranged at a discharging port of an existing extruder, so that the sizes of produced plastic particles are prone to being different, the following scheme is proposed: the discharging structure of the plastic extruder comprises a base, wherein the extruder and a screening box are respectively fixedly installed on the top of the base, a discharging pipe is arranged on the extruder, the bottom endof the discharging pipe extends into the screening box, a rotating ring is rotationally connected to the inner wall of the screening box, and a conical screen is connected to the rotating ring in a sliding mode. According to the discharging structure of the plastic extruder, a moving plate moves longitudinally, when a driving motor is started, the plastic particles can be screened, and the particles which do not pass through the conical screen can be discharged, and therefore, a purpose of screening the plastic can be achieved, the sizes of the produced plastic particles can be basically consistent, and the production quality can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a discharge structure of a plastic extruder. Background technique [0002] Plastic granules are semi-finished products in the plastic molding industry, which can be further processed into plastic products such as plastic bags. The raw materials for processing plastic granules include plastic powder and powder materials such as antistatic masterbatch, anti-adhesion masterbatch, and pearlescent masterbatch used to improve the physical properties of plastics. The plastic powder is mixed with various masterbatch powders, and the mixed powder Melting is carried out by heating, so that various raw materials are fully fused. Afterwards, the melted material is extruded into granules by using an extruder, and the required plastic granules are formed after cooling. [0003] There is no corresponding screening device at the discharge port of the existing extruder, which will ea...
