Abstract

The invention discloses a double-needle loop sewing machine with a feeding structure. The double-needle loop sewing machine comprises a machine base and a machine head; the machine head is provided with a first machine needle and a second machine needle which can move up and down; and a first rotating shuttle and a second rotating shuttle are arranged in the machine base, wherein the first rotating shuttle is matched with the first machine needle in working, and the second rotating shuttle is matched with the second machine needle in working. The first machine needle, the second machine needle, the first rotating shuttle and the second rotating shuttle are driven to work by the same motor. A first pressure foot is arranged at one side of the first machine needle; and a second pressure foot is arranged at one side of the second machine needle. The second pressure foot is arranged above a feeding plate and can move up and down. The feeding plate, the first pressure foot and the second pressure foot are connected with a slider moving mechanism. The slider moving mechanism comprises a first slider and a second slider which are used for driving the feeding plate, the first pressure foot and the second pressure foot to move in the flat surface direction. Materials can be conveniently conveyed to the first machine needle and the second machine needle by driving the first slider and the second slider to move.
