The flat bags also need to be manufactured by a bag making machine, but the rolling efficiency of the bag making machine is not high when the flat bags are manufactured. For example, in the winder of patent No. 2010105779146, the winding efficiency of the two sets of forks in rotation cannot keep pace with the bag making efficiency of the bag making machine at the present stage, and the main reason is that the winder needs to rotate half a turn each time, so that the time span is large. In addition, at the same working position, the cutting, the material receiving and the discharging are needed, and the angle of the fork is also needed to be adjusted, so that excessive time is consumed at the same position. Therefore, the efficiency is not high, and the improvement space is provided.

The invention aims to design a winding mechanism of a bag making machine, which has higher winding efficiency.
