Abstract

The invention discloses a double-needle belt loop sewing machine. When in sewing, a first needle and a second needle can be used for simultaneously sewing two ends of a belt loop, so that working efficiency is greatly improved. The first needle and the second needle are structurally matched with a first rotating shuttle and a second rotating shuttle respectively, so that the double-needle belt loop sewing machine has the advantages of high speed and low noise when in sewing. The first needle, the second needle, the first rotating shuttle and the second rotating shuttle are driven to work by the same the third motor, so that the integral driving structure is simple and maintenance is facilitated. A first presser foot and a second presser foot can be used for pressing materials needing to be sewn on a feeding plate, so that the materials move along with the feeding plate. Under the driving of a first motor and a second motor for driving feeding, the feeding plate is capable of moving in the X direction and the Y direction of a plane, and portions of the materials needing to be sewn are placed below the needles.

Description
