Wrapping bag tail flattening device of tealeaves packagine machine
Technical Field
The utility model relates to the technical field of tea packaging, in particular to a packaging bag tail flattening device of a tea packaging machine.
Background
It is known that the tail of a tea pouch is upright prior to packaging, i.e. the pouch is in a flat condition when empty, and that the tail remains upright or slightly tilted after packaging by an automatic tea packaging machine. In order to make the tea package more perfect, the tail of the packaging bag needs to be flattened, so that the tail of the packaging bag is in a transverse folding state, and therefore, the appearance is better, and the tea package is better subjected to external packaging.
In the prior art, the bag is generally flattened manually or is directly put into an outer package without being flattened, and is folded through the bag of the outer package, so that the bag is attractive in appearance, and the bag is not uniform in folding, and can be folded left and right in a disordered or even in a half-folded state.

The following describes a bag tail flattening device of a tea packaging machine in accordance with the present utility model with reference to the drawings and detailed description.
Fig. 1 is a schematic perspective view of a bag tail flattening device of a tea packing machine according to the present utility model
Detailed Description
As shown in fig. 1, the packing bag tail flattening device of the tea packing machine comprises a lifting motor mounting plate 1, wherein a lifting motor 2 is mounted on the lifting motor mounting plate 1, and the lifting motor 2 is fixed at the rear end of the lifting motor mounting plate 1. A lifting gear 3 is connected to the rotating shaft of the lifting motor 2, the lifting motor 2 drives the lifting gear 3 to rotate, the lifting gear 3 is matched with a lifting rack 4, and the lifting rack 4 is driven by the lifting motor 2 to perform lifting motion through the meshing relationship of the lifting gear 3 and the lifting rack 4.
As shown in fig. 1, the front end of the lifting motor mounting plate 1 is further provided with a lifting rail 5, the lifting rail 5 is matched with a lifting slide block 6, a left motor mounting plate 7 and a right motor mounting plate 7 are fixed on the lifting slide block 6, the lower ends of the left motor mounting plate 7 and the right motor mounting plate 7 are fixed with the lower ends of the lifting racks 4, and the lifting racks 4 can lift along the lifting rail 5 through the lifting slide block 6 with the left motor mounting plate 7 and the right motor mounting plate 7.
As shown in fig. 1, a left and right motor 8 is fixed to the left and right motor mounting plate 7. The lower ends of the left motor mounting plate 7 and the right motor mounting plate are fixedly provided with a left rack 9 and a right rack 10, the left rack 9 and the right rack 10 are respectively matched with a left slider 11 and a right slider 12, the left slider 11 and the right slider 12 are respectively fixed on a bag pushing fork left assembly 13 and a bag pushing fork right assembly 14, the left motor 8 and the right motor 8 drive the left rack 9 and the right rack 10 to move, the left rack 9 and the right rack 10 are matched with the left slider 11 and the right slider 12, and the left slider 11 and the right slider 12 drive the bag pushing fork left assembly 13 and the bag pushing fork right assembly 14 to open and close.
As shown in fig. 1, a tea bag 0 is matched between a top bag fork left assembly 13 and a top bag fork right assembly 14, and the tea bag 0 is opened by a bag opening fork 15. The left top fork assembly 13 is provided with a left lug 16, the left lug 16 is provided with a short lug 17, and a certain height folding difference space is formed between the left top fork assembly 13 and the right top fork assembly 14 through the left lug 16 and the short lug 17. When the packaged tea bag 0 which is opened by the bag opening fork 15 moves to the left top bag fork assembly 13 and the right top bag fork assembly 14, the left top bag fork assembly 13 and the right top bag fork assembly 14 are driven by the left motor 8 and the right motor 8 to be closed, and in the closing process of the left top bag fork assembly 13 and the right top bag fork assembly 14, the bag tail of the tea bag 0 is pressed on the left protruding block 16 and the short protruding block 17 of the left top bag fork assembly 13, and the bag tail of the tea bag 0 is pressed on the left protruding block 16 and the short protruding block 17 with different lengths and height difference, so that the left top bag fork assembly 13 and the right top bag fork assembly 14 start to be closed while the bag tail of the tea bag 0 is pressed on the left protruding block 16 and the short protruding block 17, and the bag tail of the tea bag 0 is pushed to be folded and flattened transversely to the right by the lifting motor 2 to be compacted, and the bag tail of the tea bag 0 is flattened transversely and forcefully and flatly.
In summary, compared with the prior art, the packaging bag tail flattening device of the tea packaging machine provided by the utility model has the advantages that the lifting motor drives the left top bag fork assembly and the right top bag fork assembly to lift up and down, the left and right motors drive the left top bag fork assembly and the right top bag fork assembly to close and open, and the left protruding block and the short protruding block enable the height folding difference space between the left top bag fork assembly and the right top bag fork assembly to transversely fold and flatten the packaging bag tail.
