Description

Cleaning device of three-screw extruder barrel

Technical Field

The utility model relates to a field especially indicates a cleaning device of three screw extruder barrels.

Background

The screw extruder depends on the pressure and the shearing force generated by the rotation of the screw, so that materials can be fully plasticized and uniformly mixed and are molded through a neck mold.

The plastic material enters the extruder from the hopper, is conveyed forwards under the drive of the rotation of the screw, and is melted under the heating action of the charging barrel and the shearing and compression actions brought by the screw in the forward movement process, so that the change among three states of glass state, high elastic state and viscous state is realized.

Under the condition of pressurization, the material in a viscous state passes through a die with a certain shape and then becomes a continuous body with a cross section similar to the die shape according to the die. Then cooling and shaping to form a glass state, thereby obtaining the workpiece to be processed.

The extruder can remain some materials on a section of thick bamboo and screw rod after using a period, and this can influence the work efficiency of extruder, and present clearance mode utilizes a stock to tie up the rag at the tip for tearing down the screw rod, and the workman is manual clears up the remain on the barrel inner wall, and this kind of clearance mode, when meetting stronger material in the adhesion, the clearance is unclean, and because the barrel is longer, the position that can not see in the middle of, manual cleaning is not thorough.

Therefore, the current three-screw extruder cleaning has two defects:

1. when materials with strong adhesion are encountered, manual cleaning is not clean, and time and labor are wasted due to the fact that only a simple cleaning tool is used;

2. during three screw rod clearance, because three screw rod groove appears in the barrel, can have partial residual material to get into the screw rod inslot of side when the clearance, lead to the clearance thoroughly inadequately.
