Description

Technical Field

[0001] This utility model relates to the technical field of extrusion molding equipment for CPLA degradable tableware, specifically to an extrusion molding equipment for CPLA degradable tableware. Background Technology

[0002] With increasing environmental awareness, biodegradable materials are being used more and more widely. CPLA, as a bio-based biodegradable material, has good biocompatibility and degradability and is widely used in the production of disposable tableware.

[0003] Currently, the material feed rate of extrusion equipment is unstable, which leads to fluctuations in material flow rate during extrusion molding, thus affecting the dimensional accuracy of the molded items. Unstable material flow rate may cause melt fracture, surface defects, or uneven texture during molding, affecting the appearance quality of tableware. If the material feed rate is insufficient, some parts of the tableware may be too thin, affecting its structural strength and durability. On the other hand, excessive material feed rate may cause local accumulation and defects. Furthermore, the traditional material conveying speed is slow, which may lead to insufficient feeding of the extruder, thus affecting the extrusion molding speed, forcing a longer molding cycle, and significantly reducing the overall production efficiency. Therefore, a CPLA biodegradable tableware extrusion molding equipment is needed to improve the above problems. Utility Model Content
