Description

Technical Field

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

[0002] As tea cakes are increasingly popular among people, their demand is also increasing day by day. The quality of tea cake packaging involves the shelf life of tea, quality assurance, and the novelty of tea cake packaging style is also one of the standards for consumers to buy. In order to gain the favor of consumers, some tea production companies carry out multi-fold collar origami for tea cakes. However, at present, most of the entire packaging process of tea cakes still uses manual packaging. Manual packaging of tea cakes cannot guarantee the packaging quality. Improper packaging will cause the tea to get damp or the tea cake to deform, reducing the visual and taste of the tea. In addition, the packaging efficiency of manually packaged tea cakes is too low, and the labor cost is high. In particular, the differences in manual multi-fold collar origami for tea cakes are large, resulting in uneven packaging quality. However, the existing tea cake packaging equipment cannot realize multi-fold collar origami for tea cakes. Therefore, the mechanization of the multi-fold collar origami packaging production line for tea cakes has become an urgent need for various tea companies.
