Description

Technical Field

[0001] This utility model relates to the field of tea cake packaging technology, and in particular to an automatic tea cake packaging machine. Background Technology

[0002] Tea cakes, a unique form of traditional Chinese tea, are regional specialty products, mainly distributed in western and southwestern Yunnan. Tea cake processing involves a series of steps, with packaging, as the final and crucial step, ensuring not only the quality of the tea cake but also its longevity. Good packaging can also influence sales and meet market demands. Tea cake packaging must also meet requirements for moisture and insect protection. While plastic sealing offers excellent airtightness compared to tea cakes, cotton paper packaging remains more popular. This is because cotton paper is breathable yet not airtight, which is beneficial for tea aging. It also has strong absorbency, preventing the absorption of external odors and ensuring the tea's quality. Furthermore, some special cotton paper packaging can reflect a region's tea culture and ethnic characteristics. However, the complexity of cotton paper packaging presents challenges for automated mechanical packaging.

[0003] Currently, most tea cake packaging machines in China use mechanical structures to flatten cotton paper to complete the packaging process. This method makes it difficult to achieve uniform crease angles on the packaging edges, greatly reducing the aesthetic appeal. Furthermore, the complex mechanical structure and high manufacturing cost of such packaging machines significantly limit their use by individual tea farmers. Therefore, problems in packaging quality, aesthetics, production efficiency, and stability urgently need to be addressed. Summary of the Invention
