[0029] This utility model relates to a double-sided, double-row quilting machine head, in which needle bars are movably mounted on both the front and rear sides of the head frame. By configuring two independent transmission components within the head frame, the driving force of the first and second drive mechanisms is applied to the needle bars on both sides of the head frame, allowing the needle bars on both sides to move independently up and down to perform the quilting process. This double-sided, double-row quilting machine head is equipped with two independent drive and transmission systems to drive the needle bars on both sides. Compared to the traditional method of using one drive mechanism to drive two rows of needle bars, the movement frequency of the needle bars is increased, thereby improving the embroidery efficiency of the quilting machine.
