Description

Technical Field

[0001] The present invention relates to the technical field of tea cake packaging equipment, and particularly to an integrated machine for inner and outer bags. Background Art

[0002] The existing Chinese patent CN201810128146.2 discloses a packaging mechanism for a tea packaging machine. Its working process is generally as follows: first, the bag is placed, then sealed after placing the bag. After sealing, the bag is directly pulled down by a pulling mechanism and pressed on the tea in the bag. Then, the upper pushing mechanism pushes upward. During shaping, the two sides in the width direction and the upper and lower sides of the tea packaging bag are squeezed and shaped, and the two sides in the thickness direction of the tea packaging bag are also shaped, so that the two sides in the thickness direction of the shaped tea packaging bag are straight and flat, and the packaging effect is good. This kind of packaging mechanism is only applicable to tea without inner bag packaging and directly outer bag packaging, such as the packaging of black tea, and is not suitable for tea that needs to be first packaged in an inner bag and then in an outer bag, such as the packaging of green tea. Therefore, this kind of tea packaging machine on the market can only be applicable to the packaging of black tea and cannot adapt to the outer bag packaging of tea cakes that need to be packaged in an inner bag first, with a single function. In this way, for tea merchants, they need to purchase two types of tea packaging machines in the factory, which undoubtedly increases the cost of tea merchants and also occupies the area of the manufacturer.
