Based on the above design, when embroidery is in progress, the tensioning swing arm 4031 swings inwards, that is, the swing arm 4031 swings inwards under the tension of the embroidery material 200, and the connecting shaft 312 rotates.

When the lower end of the chopping wheel 4041 is located in the notch of the second slot-type optical coupler 4043, the second slot-type optical coupler 4043 feeds back a signal to the synchronous conveying mechanism 402 to stop the synchronous conveying mechanism 402, and the above work is repeated to achieve synchronous feeding.

Under the action of the embroidery material 200 that passes through the material channel 503 and wraps around a part of its outer circumference, the first rotating wheel 502 performs relative rotational motion with the second rotating wheel 508. Preferably, in this embodiment, the material channel 503 is an arc-shaped material channel.

During the embroidery process, the synchronous conveying component 40 drives the conveying mechanism 302 in the storage conveying component 30, thereby feeding back to the driving component 20, that is, when working, the embroidery material 200 tightens the swing arm 4031 to swing inward, that is, the swing arm 4031 swings inward under the tension of the embroidery material 200, and the continuous When the connecting shaft 312 rotates, when the swing arm 4031 swings to a certain angle, the lower end of the chopper wheel 4041 indirectly connected to the connecting shaft 312 is located in the notch of the first slot-type optical coupler 4042, and the first slot-type optical coupler 4042 sends a feedback signal to the first motor 4021. The first motor 4021 works according to the feedback signal from the first slot-type optical coupler 4042 to drive the driving wheel 4022 to rotate. At the same time, the passive gear 4023 moves in the same direction under the action of the driving wheel 4022, so as to drive the embroidery material 200 to be synchronously transported to the rotating device 50 and then to the machine At the same time, the embroidery material 200 pulls the third thread wheel 261 and the counterweight connecting plate 262 to move upward along the slideway 3025. When leaving the sensing range of the first sensor 3027, the first sensor 3027 sends a signal to the second motor 201 to drive the second motor 201 to work, thereby driving the material discharge mechanism 301 to rotate through the driving wheel 4022 and the driven wheel 203 connected to the driving wheel 4022 through the belt 207, so as to realize the unloading of the embroidery material 200; and when the embroidery material 200 is delivered to a certain amount, the tension of the embroidery material 200 becomes smaller, and the torque Under the elastic force of the spring 4032, the swing arm 4031 swings outward, driving the chopping wheel 4041 to rotate. When the lower end of the chopping wheel 4041 is located in the slot of the second slot-type optical coupler 4043, the second slot-type optical coupler 4043 feeds back a signal to the first motor 4021 to stop the first motor 4021. At this time, the tension of the embroidery material 200 decreases, and the counterweight connecting plate 262 drives the third thread wheel 261 to fall back to the lower limit position. After the first sensor 3027 senses the counterweight connecting plate 262, it feeds back a signal to the second motor 201 to stop conveying the embroidery material 200.

The sensing assembly is used to drive the synchronous conveying mechanism to work when the swing arm assembly swings to a preset position, so that the embroidery material from the storage conveying assembly is transmitted toward the machine head.

3. The embroidery material conveying device according to claim 2, characterized in that: The synchronous conveying mechanism includes a first motor, a driving wheel and a passive gear, the first motor is installed on a mounting plate, the outer peripheral surface of the driving wheel abuts against the passive gear, the embroidery material is passed between the driving wheel and the passive gear, and the driving wheel is connected to the first motor to rotate under the drive of the first motor, and at the same time drives the passive gear to move in the same direction, thereby realizing synchronous conveying of the embroidery material.

4. The embroidery material conveying device according to claim 2, characterized in that: The swing arm assembly includes a swing arm and a torsion spring. One end of the swing arm extends outward to form a connecting shaft. The connecting shaft passes through the mounting plate, and a first slot hole is opened on one side of the swing arm. The torsion spring is sleeved on the connecting shaft and one end passes through the first slot hole.

5. The embroidery material conveying device according to claim 4, characterized in that: The sensing component includes a chopper wheel, a first slot-type optical coupler and a second slot-type optical coupler. The chopper wheel is sleeved on a rotating shaft, and the rotating shaft is located in the connecting shaft to rotate with the connecting shaft. The first slot-type optical coupler and the second slot-type optical coupler are fixed on a mounting plate, and the first slot-type optical coupler is located at the side end of the chopper wheel, and the second slot-type optical coupler is located below the chopper wheel to drive the synchronous conveying mechanism to work when the lower end of the chopper wheel is located in its slot.

6. The embroidery material conveying device according to claim 1, characterized in that: The wire wheel assembly includes a third wire wheel and a counterweight connecting plate, the counterweight connecting plate is connected to the third wire wheel through a connecting piece and is located below the third wire wheel, the first sensor is located in the lower middle part of the slide, and the upper and lower ends of the slide are respectively provided with an upper limit plate and a lower limit plate, the embroidery material is wound around the third wire wheel to drive the third wire wheel and the counterweight connecting plate to move.

7. The embroidery material conveying device according to claim 1, characterized in that: The driving assembly includes a second motor, a driving wheel, a driven wheel, a rotating shaft and a first connecting plate. The second motor is fixed to the frame through a first fixing plate. The driving wheel is connected to the second motor. The driven wheel is connected to the driving wheel through a belt. The rotating shaft is fixed to the driven wheel and its end is connected to the first connecting plate, and the discharge mechanism is passed through. The first connecting plate is connected to the discharge mechanism to drive the discharge mechanism to rotate when the driven wheel rotates.

8. The embroidery material conveying device according to claim 1, characterized in that: The rotating device also includes a protective sheet located in the hub shell, and the protective sheet includes an arc-shaped plate, both ends of the arc-shaped plate are bent outward to form a buckle, and the buckle is located below the two ends of the material channel to limit the position of the embroidery material.

9. An embroidery machine, characterized in that: The embroidery machine comprises the embroidery material conveying device as described in any one of claims 1-8.
