Abstract

The invention discloses a plastic extruder which comprises a cylinder and a screw rod arranged in the cylinder. An extruding channel is formed between the outer wall of the screw rod and the inner wall of the cylinder. A feeding port, an exhaust port, a discharging port and a dirt discharging opening are sequentially formed in the cylinder along the extruding channel. The plastic extruder further comprises a filtering part. The filtering part is connected to the connecting position of the discharging port and the extruding channel. By means of the plastic extruder, in the flowing direction of the extruding channel, the discharging port is located in the upstream part of the dirt discharging opening, impurities and plastic particles which are not melted are filtered out of the discharging port through a filtering part, due to the fact that the dirt discharging opening is located in the downstream part of the discharging port, discharging cannot be affected by dirt discharging, and the discharging port can achieve continuous discharging.

Description

technical field [0001] The invention relates to plastic processing machinery, in particular to a plastic extruder. Background technique [0002] In plastic processing, the plastic extruder is usually called the main machine, because many methods of plastic processing, such as pipes, films, holding materials, monofilaments, extrusion nets, granulation, etc., are preceded by plastic extrusion. step. [0003] figure 1 It is a structural schematic diagram of a plastic extruder in the prior art, such as figure 1 As shown, the plastic extruder includes a barrel and a screw built in the barrel, an extrusion channel is formed between the outer wall of the screw and the inner wall of the barrel, and the extrusion channel is formed along the barrel on the barrel. The pressure channel is sequentially provided with a feed port, an exhaust port and a discharge port. When working, the material enters the extrusion channel through the feed port, the gas in the material overflows from th...
