A tea bag packaging machine and its outer bag heat sealing assembly

Abstract

The invention discloses a teabag packing machine and an outer bag heat-sealing assembly thereof. The outer bag heat-sealing assembly comprises an installing bracket, a driving mechanism, a first heat-sealing plate and a second heat-sealing plate. The driving mechanism comprises a rotating driving piece, a first connecting component and a second connecting component. One end of the first connecting component is connected to the rotating driving piece, and the other end of the first connecting component is connected to the first heat-sealing plate. One end of the second connecting component is connected to the rotating driving piece, and the other end of the second connecting component is connected to the second heat-sealing plate. The movement direction of the first heat-sealing plate and the movement direction of the second heat-sealing plate are opposite under the drive of the rotating driving piece. The movement of the first heat-sealing plate and the movement of the second heat-sealing plate are both driven by the same driving mechanism. The first heat-sealing plate, the second heat-sealing plate and the driving mechanism are linked together to form an integral structure. The first heat-sealing plate and the second heat-sealing plate are not mutually independent but associated. Compared with a heat-sealing assembly of the prior art, other intermediate driving pieces are no longer depended on, and the movement is stable and reliable.

Description

technical field [0001] The invention relates to a tea bag packaging machine and an outer bag heat sealing assembly thereof. Background technique [0002] The tea bag packaging machine includes a feeding component, an inner bag heat-sealing component, an outer bag heat-sealing component and a main transmission box component. When working, first put the material into the inner bag, and then put the inner bag into the outer bag . The traditional outer bag heat-sealing assembly includes two relatively moving heat-sealing plates. The driving mechanisms of the two heat-sealing plates are separated and driven by their own independent air cylinders, which makes the whole mechanism complicated. [0003] Chinese patent CN202449254U (authorized announcement date is 2012.09.26) discloses an outer bag sealing assembly, which includes a first sealing rod and a second sealing rod for sealing plastic bags, the first sealing rod and the second sealing rod Relatively set, the first sealing ...
