Detailed ways

As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, an automatic seaming device includes a sewing machine, a motor, a runner, a gear, a shelf, a pressing wheel, a feeding frame and iron rods.

The sewing machine 2 is installed on the table top 1, and the rotating shaft A4 of the motor 3 installed below the table top 1 is connected with the turntable 6 of the sewing machine 2 through the belt A5.

The rotating shaft B 7 of the turntable 6 is connected to the rotating wheel A 9 through the belt B 8 , and the rotating shaft C 10 of the rotating wheel A 9 is connected to the rotating wheel B 12 through the chain A 11 .

The rotating shaft D 13 of the runner B 12 is connected with the rotating shaft E 15 at one end of the cross bar A 17 on the shelf 18 through the chain B 14, and the gear A 16 on the cross bar A 17 is connected with the gear on another cross bar below the shelf 18 B 30 is connected, and the other end of the cross bar A 17 is provided with a pressure roller 19 .

The feed frame 27 is fixed on the table top 1 close to the needle 28 of the sewing machine 2, the cross arm 26 drawn from one end of the feed frame 27 is provided with a cross bar B 25, and the side of the feed frame 27 is between the sewing machine 2 and the cross bar B 25 A horizontal plate 23 is provided, and the lower end of the horizontal plate 23 is provided with an arc-shaped iron rod 22 .

A U-shaped positioning bar 20 is arranged between the sewing machine 2 and the pressure roller 19 on the table top 1 .

The working principle of the present utility model is as follows. The shaft shaft A 4 of the motor 3 rotates the rotating disk 6 of the sewing machine 2 through the belt A 5 to provide power for the sewing machine. Simultaneously, the rotating shaft rotating shaft A of motor 3 makes two by rotating shaft B 7, belt B 8, runner A 9, rotating shaft C 10, chain A 11, runner B 12, rotating shaft D 13, chain B 14 and rotating shaft E 15 The pinch wheel 19 rotates. The raw material tape 24 and thread 29 enter the feed frame 27 through the cross bar B 25, and the tape 24 becomes sideways when it enters the horizontal plate 23, and the thread 29 has been embraced in the middle of the cloth tape 24 when the tape 24 exits the end of the cross bar B25 At this moment, one end of iron rod 22 is pressed on the folded edge of cloth tape 24, and cloth tape 24 is sent under the needle 28 of sewing machine 2, and sewing machine 2 sews cloth tape 24, and thread 29 is sewn in the middle of cloth tape 24. The cloth tape 21 sewn by the sewing machine enters the middle of the two pinch rollers 19 by the positioning rod 20 . Under the pulling of the cloth tape 21 sewn by the pinch wheel 19, the sewing machine 2 continues to sew the cloth tape 24 from the feed frame 27 li.

The utility model can also be used for other overlock sewing work not including thread.
