Abstract
The utility model discloses a drive mechanism for a multi-needle-rod sewing machine. The rotating angle of a motor is automatically controlled through procedures, and therefore the movement position of needle rod installing frames can be conveniently controlled. When the needle rod installing frames move, all needle rods are guided through a first horizontal guiding groove and a second horizontal guiding groove, and when the motor drives the needle rod installing frames to move to one stroke position, the needle rod corresponding to the stroke position is delivered to a clamping groove of a needle rod drive block and is driven to work through the needle rod drive block. Therefore, the number of the needle rod installing frames can be two or three or more so as to meet the requirement for sewing a double-color pattern or a three-color pattern or a multi-color pattern, and the drive mechanism has the advantages of being simple in structure and automatic in control. The drive mechanism solves the problem that when a single-needle-rod sewing machine and a double-needle-rod sewing machine sew a pattern, the kinds of colors of upper threads are insufficient, and the threads need to be replaced manually.
