[0002] At present, in the wine-making process, many enterprises still manually tie the mouths of wine jars. When tying the mouth of a wine jar, a worker needs to press materials such as lotus leaves, peach blossom paper, and mud covers that have been covered in advance with one hand, and at the same time, take a woven belt with the other hand, wind it around the mouth of the wine jar, then the two hands cooperate to tighten the woven belt, and then tie a knot. Finally, another worker performs the trimming work. Just to complete the mouth-tying action, it takes 10 - 13 seconds for two skilled workers to cooperate to complete it, and the quality of mouth-tying cannot be guaranteed. Especially the tightening and knotting actions in the wine jar mouth-tying action play a key role in the quality of wine jar mouth-tying.
