Description

Technical Field

[0001] This utility model relates to the field of extruder technology, specifically to an automatic feeding pellet extruder. Background Technology

[0002] Extruders are a type of plastics machinery, originating in the 18th century. Based on the angle between the material flow direction at the die head and the screw centerline, extruders can be classified into right-angle die heads and angled die heads, among others. Screw extruders rely on the pressure and shear force generated by the rotating screw to fully plasticize and uniformly mix the material, which is then shaped through a die. Plastic extruders can be broadly classified into twin-screw extruders, single-screw extruders, and less common multi-screw extruders and screwless extruders.

[0003] When feeding a plastic extruder, the operator needs to fill the feed hopper with the material. However, during operation, the material accumulates inside the feed hopper, which can easily cause the material to jam the threaded rod inside the extruder. Furthermore, because the opening of the feed hopper faces upwards, dust and other impurities can easily enter the feed hopper, resulting in defects in the produced products and clogging the discharge port of the plastic extruder. Utility Model Content

Then, the material enters the main body through the discharge port and feed port on the shell. The material is fed evenly, which can prevent the material from clogging the feed port and prevent the threaded rod from getting stuck. Attached Figure Description

Then the user starts the motor 141, and the output end of the motor 141 drives the roller 142 to rotate, so that the material in the collection box 145 can rise with the rotation of the roller 142. During the material climbing process, the spiral filter screen 143 can remove impurities from the material. Then the material enters the body 6 from the feed inlet 13, and the impurities filtered out can be cleaned by the user through the screw cap 144.

[0033] In this embodiment, the output end of the motor 141 passes through the housing 140 and is connected to the roller 142.

The user then starts the motor 141, which drives the roller 142 to rotate, causing the material in the collection box 145 to rise with the rotation of the roller 142. During the material's ascent, the spiral filter screen 143 removes impurities from the material. The material then enters the main body 6 through the feed inlet 13. The user can clean the impurities in the shell 140 by using the screw cover 144. The feeding structure 14 drives the material to climb and feed, ensuring that the material enters the feed inlet 13 evenly, preventing blockage. After entering the main body 6, the material is melted by the heating tube 7 and the heater 9.
