In order to achieve the aim of the invention, the invention comprises a sewing machine, a motor, an air injection device box body and a pressure valve;
the pedal of the sewing machine is connected with a fixed start-stop switch travel pin through a pedal connecting rod I, an air valve control rod spring and a fixed spring travel pin are arranged on the fixed start-stop switch travel pin, and the fixed start-stop switch travel pin is connected with an air injection start-stop switch;
one end of the air injection start-stop switch is connected with the pedal connecting rod II, the other end of the air injection start-stop switch is connected with the motor braking connecting rod, and the motor braking connecting rod is connected with the motor;
the pedal connecting rod is connected with the pedal through a pedal connecting pin;
the pedal connecting rod I and the pedal connecting rod II are arranged on an air jet device box body, and the air jet device box body is connected with a pressure valve;
the pressure valve is connected with an air outlet pipe through an air release valve switch in the box body of the air injection device, the air outlet pipe is connected with an air blowing copper pipe of the sewing machine, the air blowing copper pipe is fixed on the sewing machine through a fixed copper pipe pin, and the air blowing copper pipe is connected with a hemming pull cylinder of the sewing machine; the air release valve switch is connected with the motor.
The pressure valve is connected with a compressed air source through an air inlet pipe, and the pressure of the air source is 0.3-0.4Mpa.
The hemming pull cylinder of the sewing machine is provided with an air inlet hole.
When the sewing machine is used, an operator steps on the pedal of the sewing machine by foot, the pedal connecting rod drives the air injection start-stop switch to deflate, the pressure valve is connected with the air outlet pipe through the air release valve switch, the air outlet pipe is connected with the air blowing copper pipe of the sewing machine, the air blowing copper pipe is connected with the hemming pull cylinder of the sewing machine, and compressed air blows wool yarns on the edge of the sewing head into the sewing head of the hemming pull cylinder, so that the thread ends are prevented from being attached to the outside of the fabric. The structure is simple, the operation is convenient, the quality is stable, the labor cost of cleaning and shearing the wool yarns can be saved, and the method is suitable for the fabric hemming process of more wool yarns for clothing and home textiles.

Detailed Description
As shown in fig. 1, 2 and 3, the invention mainly comprises a sewing machine 19, a motor 8, an air injection device box 14 and a pressure valve 12; the pedal 1 of the sewing machine 19 is connected with a fixed start-stop switch travel pin 7 through a pedal connecting rod I2, an air valve control rod spring 4 and a fixed spring travel pin 5 are arranged on the fixed start-stop switch travel pin 7, and the fixed start-stop switch travel pin 7 is connected with an air injection start-stop switch 6; one end of the air injection start-stop switch 6 is connected with the pedal connecting rod II 3, the other end of the air injection start-stop switch is connected with the motor braking connecting rod 9, and the motor braking connecting rod 9 is connected with the motor 8; the pedal connecting rod I2 is connected with the pedal 1 through a pedal connecting pin 15; the pedal connecting rod I2 and the pedal connecting rod II 3 are arranged on the air jet device box body 14, and the air jet device box body 14 is connected with the pressure valve 12; the pressure valve 12 is connected with the air outlet pipe 10 through an air release valve switch 13 in the air injection device box 14, the air outlet pipe 10 is connected with the air injection device box 14 through an air outlet pipe connector 16, the air outlet pipe 10 is connected with an air blowing copper pipe 17 of a sewing machine 19, the air blowing copper pipe 17 is fixed on the sewing machine 19 through a fixed copper pipe pin 18, the air blowing copper pipe 17 is connected with a hemming pull tube of the sewing machine, and the air release valve switch 13 is connected with the motor 8; the pressure valve 12 is connected with a compressed air source through an air inlet pipe 11, and the pressure of the air source is 0.3-0.4Mpa. The pressure of the air inlet pipe 11 can be properly adjusted according to different varieties; the hemming pull cylinder of the sewing machine is provided with an air inlet hole.
When the novel air inlet pipe 11 is used, the air inlet pipe 11 is connected with a compressed air source, the air blowing copper pipe 17 is connected with a hemming pull cylinder of a sewing machine, an operator steps on the pedal 1 of the sewing machine by foot, and the pedal connecting rod I2 drives the fixed start-stop switch travel pin 7 to press down the air valve control rod spring 4. When the fixed start-stop switch travel pin 7 is pressed to the upper edge of the air jet device box body 14, the pedal connecting rod II 3 runs downwards, and the motor 8 is driven to run through the motor brake connecting rod 9. The motor 8 drives the air release valve switch 13 to act, and air blown out by the air blowing copper pipe 17 is opposite to the hemming pull cylinder of the sewing machine, so that the wool yarn ends of the edge stitch ends of the fabric are blown into the stitch ends, and the phenomenon that the yarn ends are attached to the outside of the fabric is avoided. When the operator returns to stop the sewing machine pedal 1, the air valve control rod spring 4 rebounds the air release valve switch 13 to the original position, so that the foot-operated air release is realized, the foot returns to stop air, and the intermittent requirement of sewing hemming and yarn blowing is met.
