[0032] like Figure 1-6 As shown, the dual-motor driven sewing machine proposed in the present application includes a body 1 and a head 4 arranged at the upper end thereof, a first motor 2 is arranged on the side of the head 4, the needle is started to work and sew by the first motor 2, a groove is opened at the upper end of the body 1 and is located behind the needle at the bottom end of the head 4, a material guide mechanism 3 is arranged in the groove, and the material guide mechanism 3 is driven by a second motor 6, and the second motor 6 is installed on one side inner wall of the body 1.

[0033] The bottom end of the machine body 1 is provided with a material supporting mechanism 5 used in conjunction with the material guiding mechanism 3, for supporting the sewn clothes to prevent the sewn parts (clothes or other materials) from falling to the ground.

[0034] Specifically, the material guide mechanism 3 includes a pair of transmission shafts 34 rotatably connected in the groove, and the outer sides of the two transmission shafts 34 are jointly driven by a conveyor belt 31, and the upper end of the conveyor belt 31 is flush with the upper end surface of the machine body 1, and the sewn part (cloth or other materials) is directly pushed to the upper end of the conveyor belt 31. The machine body 1 is provided with an inner cavity located on one side of the groove, and one end of the two transmission shafts 34 extends into the inner cavity and is connected by a transmission belt assembly, and the transmission belt assembly includes a first pulley fixedly sleeved on the ends of the two transmission shafts 34, and the two first pulleys are connected by a first belt transmission (not shown in the figure); the upper end surface of the machine body 1 is provided with a connecting groove located on the side of one of the transmission shafts 34, and the corresponding transmission shaft 34 extends into the connecting groove, and the output shaft of the second motor 6 is connected by a pulley member 35, and the pulley member 35 includes a second pulley fixedly sleeved on the transmission shaft 34 in the connecting groove and the output shaft of the second motor 6, and the two second drives are connected by a second belt transmission.

[0035] Among them, the outer end of the groove is connected to a guide plate 33 located on the outside of the conveyor belt 31, and the outer end of the guide plate 33 is tilted downward; the inner wall of the groove is provided with a connecting soft hair head 32, and the connecting soft hair head 32 is located at the outer edge of the conveyor belt 31, which can protect clothes or other materials and prevent external threads or debris from entering the groove.

[0036] Specifically, the supporting mechanism 5 includes a slide groove 53 provided on the rear end face of the machine body 1 and located below the soft hair head 32. A support plate 54 is slidably inserted in the slide groove 53 for supporting the sewn clothes. The outer surface of the support plate 54 is smooth and flat. The supporting mechanism 5 also includes a support slide bar 51 connected to the lower end face of the machine body 1. An L-shaped slide bar 52 is slidably penetrated and connected in the support slide bar 51. One end of the L-shaped slide bar 52 is fixedly connected to the support plate 54.

One end of the push-pull rod 55 is fixedly connected to a limit block.

[0037] The working principle of this embodiment is as follows: when in use, the first motor 2 and the second motor 6 are started, the first motor 2 is started to drive the needle to start sewing, and the section worker who has completed sewing pushes it to the upper end of the conveyor belt 31 with manual assistance. The output shaft of the second motor 6 rotates through the pulley 35 to drive one of the transmission shafts 34 to rotate, and then drives the other transmission shaft 34 to rotate through the transmission belt assembly. The two transmission shafts 34 rotate to drive the conveyor belt 31 (the transmission direction of the conveyor belt 31 is the rear of the machine body 1), which can guide and convey the sewn clothes and materials, make the sewing more streamlined, and avoid the wrinkles of clothes and materials accumulating behind the needle, affecting the sewing effect. By arranging the connecting soft hair head 32 on the inner wall of the groove, the gap between the machine body 1 and the conveyor belt 31 is connected. It prevents clothes and materials from being stuck in the gap, and prevents thread ends or debris from falling into the gap. By setting a supporting mechanism 5 at the bottom end of the machine body 1, the push-pull rod 55 is pushed in the direction of the supporting slide bar 51 before sewing, and then the support plate 54 is pushed outward through the L-shaped slide bar 52, which can support the clothes and materials transported by the material guiding mechanism 3 and prevent the clothes and materials from falling to the ground.
