Description

Technical Field

[0001] The utility model relates to the technical field of clothing sewing equipment, in particular to a small folding bag mechanism. Background Art

[0002] During the clothing production process, many garments require pockets. Traditionally, pockets are pasted manually. Later, there were many automatic pocket pasting machines, but these pocket pasting machines were also conventional pocket pasting machines. However, with the continuous improvement of living standards, many small pockets need to be pasted automatically, but the current market is basically not suitable for pasting small pockets, especially for children's clothing. Their pockets are relatively small, and the guide mounting base and the bag baffle plate are very small. It is very difficult to install the left and right cylinder folding knife assemblies and the front and rear cylinder folding knife assemblies on this very small installation base and above the bag baffle plate. If the left and right and front and rear cylinders and folding knife assemblies are forced to be installed, the folding knife will extend to the edge of the bag baffle machine, and the folding knife will become very long, resulting in unstable folding and reduced quality.
