Description

Technical Field

[0001] The utility model relates to the technical field of plastic extruders, in particular to a plastic extruder which is convenient for removing impurities. Background Art

[0002] In the current production and processing of PE communication equipment silicon core tubes, PPR pipes and some other plastic parts, plastic extruders are usually required for processing. Plastic extruders not only have low energy consumption, but also can reduce production costs. However, since some of the raw materials for the production of plastic parts are recycled raw materials, even after cleaning and then processing, there will still be some impurities. During the extrusion molding process of the plastic extruder, the impurities mixed in the raw materials can easily cause the machine head to be blocked, resulting in the subsequent plastic extruder being unable to work normally, which not only reduces the processing quality, but also reduces production efficiency.

[0003] Based on the above, the inventors have found the following problems: the existing plastic extruders do not have an impurity removal function when in use, resulting in impurities mixed in the raw materials easily causing the die to become clogged, thus affecting production efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a plastic extruder that is easy to remove impurities is provided, in order to achieve a purpose with greater practical value. Utility Model Content
