Technical Field

The invention relates to the technical field of packaging machines, in particular to a vibrating compaction device for tea packaging.

Background

Tea after the system of frying often need pack the sale, adopts plastic packaging bag or paper wrapping bag to pack the tealeaves in bulk more, in order to guarantee the quality of finished product tealeaves, both need guarantee during the packing that tealeaves does not receive destruction, will carry out accurate ration to every wrapping bag tea of adorning again, prevent that the not enough of same batch product weight, uneven problem from appearing, the tealeaves packing mode that present tea manufacture factory adopted generally includes following several kinds: manual packing, batch packing by adopting a tea packing machine and batch packing by adopting a manpower-assisted machine. However, the existing packaging methods have the following defects:

1. the manual packaging has the problems of low speed and high labor intensity, and the addition amount of each time is difficult to control when the bags are manually packaged, so that the addition amount is possibly excessive or insufficient.

2. In order to ensure that the bagged tea leaves reach a sufficient amount, the tea leaves need to be piled up during the bagging process so that the subsequent tea leaves can be added continuously, the packaging bag is generally shaken by hands during manual bagging, if the tea leaves cannot be piled up, the tea leaves need to be pressed downwards by hands, and as the leaves of some fried tea leaves (such as white tea) are longer and crisper, if the force is not controlled well during pressing, the tea leaves can be broken, so that the quality of the tea leaves is influenced; the conventional tea leaf packaging machine generally has no pressing function, so that tea leaves are easily shaken out when the packaging bag is shaken, the stacking effect is difficult to control, and the tea leaves are likely to be stacked on a sealing line to influence the sealing performance and the attractiveness of the seal.
