Description

Technical Field

[0001] The utility model relates to the technical field of degradable plastic production, in particular to an extruder for the production of degradable plastic. Background Art

[0002] Degradable plastics refer to a type of plastic whose products have various properties that meet the requirements of use, and whose properties remain unchanged during the shelf life. After use, they can be degraded into environmentally harmless substances under natural environmental conditions. Therefore, they are also called environmentally degradable plastics. Extrusion is a processing method in plastics processing that refers to the action between the barrel and screw of the extruder, while the material is plasticized by heat and pushed forward by the screw. Extrusion devices are also used in the production and processing of degradable plastics.

[0003] When the existing extruder for producing biodegradable plastics is in use, the feed hopper is in an inverted cone shape and its discharge port is small. When the material is discharged under the action of gravity, the discharge port of the feed hopper is easily blocked, thereby reducing the processing efficiency of the extruder.

The extruder for producing degradable plastics solves the problem that the existing extruder for producing degradable plastics directly dumps the raw materials into the extruder when in use, does not have the effect of screening unqualified plastic particles, and reduces the quality of the raw materials.

[0005] Although the above patent solves the problem that the existing extruder for producing biodegradable plastics directly pours the raw materials into the extruder during use, which does not have the effect of screening out unqualified plastic particles, thereby reducing the quality of the raw materials; however, the device lacks the function of adjusting the height of the equipment, making it convenient for workers of different heights to use it.

[0006] Therefore, it is necessary to invent a kind of extruder for producing degradable plastics to solve the above problems. Utility Model Content
