Description

Extruder capable of cleaning feed box

Technical Field

The utility model relates to the field of extruders, in particular to an extruder capable of cleaning a feed box.

Background

The screw extruder relies on pressure and shearing force generated by screw rotation, so that materials can be fully plasticized and uniformly mixed, and the materials are molded through a die. Plastic extruders can be classified basically into twin-screw extruders, single-screw extruders and less common multi-screw extruders and screw-less extruders.

The plastic material enters the extruder from the feed box, is conveyed forward under the drive of the rotation of the screw rod, and is heated by the feed cylinder, sheared and compressed by the screw rod in the forward movement process, so that the material is molten, the change among the three states of a glass state, a high-elastic state and a viscous state is realized, and under the condition of pressurization, the material in the viscous state passes through a die with a certain shape, and then the material is formed into a continuous body with a cross section and a die shape according to the die. And then cooling and shaping to form a glassy state, thereby obtaining the finished product required to be processed.

After the extruder is used for a long time, the feed box can accumulate a large amount of residues of materials, if the extruder is not cleaned, the production and the manufacture are continued, the accumulated residues can influence the newly produced products, the quality of the products is reduced, and normally, the cleaning feed box is cleaned by workers stretching the feed box through telescopic rods, and the residues at corners in the box are difficult to clean because the walls of the box are difficult to clean due to the fact that the walls of the box are high
