Description

Technical Field

[0001] This utility model relates to the field of weighing and packaging technology, and in particular to a screw-type weighing and filling packaging device. Background Technology

[0002] Filling packaging is a process of filling products into appropriate packaging containers according to specific quantities and specifications. For example, solid granules, powders, and liquids are filled into packaging bags, boxes, bottles, and other packaging forms using specialized filling equipment. While ensuring the accuracy of product quality and quantity, it also focuses on the sealing, integrity, and aesthetics of the packaging to achieve multiple goals such as effective product protection, convenient storage and transportation, favorable marketing, and meeting consumer needs. It is a crucial and important part of modern product packaging.

[0003] A screw-type weighing and filling packaging device is a highly efficient and precise packaging equipment. It primarily utilizes the rotation of a screw to transport materials. By precisely controlling the screw's speed and rotation time, it achieves quantitative material delivery, thereby completing the weighing and filling operation. This device is suitable for packaging various powdery and granular materials, possessing high packaging accuracy and speed, effectively reducing material waste. It also features a relatively compact structure, convenient operation and maintenance, and can be flexibly adjusted according to different packaging needs, helping to improve production efficiency and packaging quality, reduce production costs, and meet the diverse market requirements for product packaging. However, in current technologies, it is impossible to effectively and precisely transport materials. Instead, operators manually feed the material to a designated location before packaging, which leads to material waste and reduced work efficiency. Utility Model Content
