Description

Technical Field

[0001] The utility model relates to the technical field of extruders, in particular to an extruder feeding device which is convenient for controlling the amount. Background Art

[0002] As we all know, extruder is a type of plastic machinery, which originated in the 18th century. According to the direction of the extruder head and the angle between the center line of the screw, the extruder head can be divided into right-angle head and bevel head. The screw extruder relies on the pressure and shear force generated by the rotation of the screw to fully plasticize and evenly mix the material and form it through the die.

[0003] Traditional feeding devices often have problems with inaccurate material flow control, resulting in unstable product quality and material waste, and material blockage is prone to occur during the feeding process. When the feeding barrel is blocked, the material cannot enter the extruder normally, resulting in production line interruption and reduced production efficiency. At the same time, the adhesion of the material to the side wall of the feeding barrel will also affect the fluidity and uniformity of the material, further reducing production efficiency.
