Description

Technical Field

[0001] The invention relates to the technical field of tea cake packaging, in particular to an automatic tea cake packaging machine and a packaging method thereof. Background Art

[0002] Tea cakes are a unique form of traditional Chinese tea and a regional specialty product. They are mainly distributed in western and southwestern Yunnan. Tea cake processing requires a series of processes. Packaging, as the last process, is a very important link. It is not only a guarantee of tea cake quality, but also a key factor in the long-term preservation of tea cakes. At the same time, a good appearance packaging can affect the sales of tea cakes and meet market requirements. The packaging of tea cakes also needs to meet the requirements of moisture-proof and insect-proof. Compared with the plastic sealing of tea cakes, although the plastic sealing performs well in isolating air contact, cotton paper packaging is still more popular with the public. On the one hand, cotton paper has the characteristics of strong air permeability and is dense but not sealed, which is more conducive to the aging of tea cakes. On the other hand, it has strong adsorption, which can avoid absorbing external odors and odors, and avoid tea affecting the quality. More importantly, some special cotton paper packaging can reflect the tea culture and national characteristics of a place, but complex cotton paper packaging has certain difficulties in realizing automated mechanical packaging.

[0003] At present, most of the existing tea cake packaging machines in China use a mechanical structure to flatten cotton paper to complete the packaging process. This method makes it difficult to achieve a uniform crease angle on the edge of the package, which greatly reduces the aesthetics.
