understandably, the embroidery material 200 required by the embroidery machine disk embroidery head in the embroidery process is provided by the embroidery material conveying device 1 of the invention, the largest outer diameter of the discharging mechanism 301 for storing the embroidery material 200 is not limited, the embroidery material 200 can be completely stored in one discharging mechanism 301, the synchronous conveying component 40 drives the conveying mechanism 302 in the storage conveying component 30 in the embroidery process so as to feed back to the driving component 20, namely, when the embroidery material 200 works, the swing arm 4031 is tensioned to swing inwards, namely, the swing arm 4031 swings inwards under the tension action of the embroidery material 200, the connecting shaft 312 rotates, when the swing arm 4031 swings to a certain angle, the lower end of the chopping wheel 4041 indirectly connected with the connecting shaft 312 is positioned in the notch of the first notch optical coupler 4042, the first notch 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 notch optical coupler 4042 to drive the driving wheel 4022 to rotate, meanwhile, the driven roller 4023 moves in the same direction under the action of the driving wheel 4022 to drive the embroidery material 200 to be synchronously conveyed to the rotating device 50 so as to be conveyed to the nose nozzle, meanwhile, the embroidery material 200 pulls the third roller 261 and the counterweight connecting plate 262 to move upwards along the slide 3025, when the embroidery material leaves the induction range of the first inductor 3027, the first inductor 3027 sends a signal to the second motor 201 to drive the second motor 201 to work, so that the emptying mechanism 301 is driven to rotate by the driving wheel 4022 and the driven wheel 203 connected with the driving wheel 4022 through the belt 207, and the emptying of the embroidery material 200 is realized; when the embroidery 200 is fed to a certain amount, the tension of the embroidery 200 is reduced, the swing arm 4031 swings outward under the elastic force of the torsion spring 4032 to drive the chopper wheel 4041 to rotate, when the lower end of the chopper wheel 4041 is located in the notch of the second slot type optocoupler 4043, the second slot type optocoupler 4043 feeds back a signal to the first motor 4021 to stop the first motor 4021, the tension of the embroidery 200 is reduced at this time, the counterweight connecting plate 262 drives the third wire 261 to fall back to the lower limit position, and the first sensor 3027 senses the counterweight connecting plate 262 and then feeds back a signal to the second motor 201 to stop feeding the embroidery 200.

Referring to fig. 8 and 9, fig. 8 and 9 show an embodiment of the embroidering machine 100 according to the present invention. In the embodiment shown in the drawings, the embroidery machine 100 includes the embroidery material conveying device 1, and referring to fig. 8 and fig. 9 and also referring to fig. 1 to 7, the rotating device 50 is fixed on a machine head 2 through a fixing plate 506, and the machine head 2 is mounted on a rectangular frame 101 of the embroidery material conveying device 1, and the machine head 2 is a machine head of an embroidery machine commonly used in the art and is not described herein again. In the invention, the embroidery material 200 sequentially winds around the second thread wheel 3024, the third thread wheel 261 and the first thread wheel 3023 from the discharging mechanism 301, passes through a space between the driving wheel 4022 and the driven gear wheel 4023, passes through the through hole 311 of the swing arm 4031, passes through the material passage 503, penetrates into the hub shell 501, passes through part of the outer peripheral surface of the first rotating wheel 502, and then passes out to the nozzle 21 of the machine head 2 through the second slotted hole 504, the embroidery material 200 is synchronously conveyed by the conveying mechanism 302 and the synchronous conveying mechanism 402, and the rotation device 50 can provide buffer for the embroidery material 200 which passes out to the nozzle 21 of the machine head 2, so that the embroidery material 200 is prevented from being clamped by the machine head 2 to damage the embroidery material 200, the integrity of the embroidery material 200 is ensured, and the yield of embroidery processing.

The foregoing is considered as illustrative of the preferred embodiments of the invention and is not to be construed as limiting the invention in any way. Various equivalent changes and modifications can be made by those skilled in the art based on the above embodiments, and all equivalent changes and modifications within the scope of the claims should fall within the protection scope of the present invention.
