Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 2 A thread feeding device for a quilting machine includes a frame 1. Mounting plates 2 are fixedly connected to both ends of one side of the frame 1. A feeding assembly 3 is arranged between the two mounting plates 2. The feeding assembly 3 includes a fixed rod 301, a fixed frame 302, a conveying wheel 303, a first transmission wheel 304, a rotating rod 305, a second transmission wheel 306, a transmission belt 307, a drive motor 308, and bolts 309. The fixed rod 301 is arranged between the two mounting plates 2. At least one fixed frame 302 is arranged on the surface of the fixed rod 301. A conveying wheel 303 is arranged at the bottom of one side of the fixed frame 302. A first transmission wheel 304 is arranged at the bottom of the other side of the fixed frame 302. A rotating rod 305 is arranged inside the fixed frame 302. A second transmission wheel 306 is arranged on one side of the fixed frame 302. A transmission belt 307 is arranged between the second transmission wheel 306 and the first transmission wheel 304. A drive motor 308 is arranged at one end of the rotating rod 305. Bolts 309 are arranged on the top of the fixed frame 302.

[0025] By setting up the feeding component 3, the embroidery thread can be conveyed in the same way, and the embroidery thread conveying can be kept synchronous. When the drive motor 308 is started, it works with the rotating rod 305, the second transmission wheel 306, the transmission belt 307, and the first transmission wheel 304 to drive multiple conveying wheels 303 to rotate synchronously and output the embroidery thread.

[0026] Please see Figures 1 to 2 The two ends of the fixed rod 301 are fixedly connected to the mounting plate 2. The fixed frame 302 is fixedly connected to the fixed rod 301 by bolts 309. The conveying wheel 303 is rotatably connected to one side of the fixed frame 302. The first transmission wheel 304 is fixedly connected to one end of the conveying wheel 303. The rotating rod 305 is rotatably connected to the mounting plate 2 and passes through the interior of the fixed frame 302. The second transmission wheel 306 is fixedly connected to the surface of the rotating rod 305. The first transmission wheel 304 and the second transmission wheel 306 are rotatably connected by a transmission belt 307. The drive motor 308 is fixedly connected to one side of the frame 1 and the output shaft of the drive motor 308 is fixedly connected to one end of the rotating rod 305. The bolt 309 is threadedly connected to the top of the fixed frame 302 and the bottom end of the bolt 309 is in contact with the surface of the fixed rod 301.

[0027] When the drive motor 308 is started, it can drive the rotating rod 305 to rotate, and at the same time drive the second transmission wheel 306 to rotate. Through the transmission belt 307, it can drive the first transmission wheel 304 to rotate, and then drive the conveyor wheel 303 to rotate. It can drive multiple conveyor wheels 303 to rotate synchronously at the same time.

[0028] Please see Figures 3 to 4A tension roller 7 is rotatably connected to one side of the frame 1. An adjustment assembly 8 is provided at both ends of the tension roller 7. The adjustment assembly 8 includes a fixed plate 801, a screw 802, a knob 803, a movable plate 804, a spring 805, and a connecting plate 806. A fixed plate 801 is fixedly connected to both ends of one side of the frame 1. A screw 802 is threadedly connected to the top of the fixed plate 801. A knob 803 is fixedly connected to the top of the screw 802. A movable plate 804 is movably connected to the bottom of the screw 802. A spring 805 is fixedly connected to the bottom of the movable plate 804. A connecting plate 806 is fixedly connected to the bottom of the spring 805. The two connecting plates 806 are respectively sleeved on both ends of the tension roller 7.

[0029] The tension of the embroidery thread can be adjusted by setting the adjustment component 8. By rotating the knob 803, the tension roller 7 can be raised and lowered in conjunction with the screw 802, the movable plate 804, the spring 805, and the connecting plate 806. When the tension roller 7 moves downward, it squeezes the thread 10 to keep the thread 10 taut.

[0030] Please see Figure 1 The top of the frame 1 is fixedly connected to a slide rail 4. At least one guide roller 5 is installed on the surface of the slide rail 4. A limit groove 6 is opened on the surface of the guide roller 5. A wire spool 9 is provided on one side of the frame 1. A wire body 10 is provided on the top of the wire spool 9. The guide roller 5 is slidably connected to the slide rail 4. The positions of several guide rollers 5 can be adjusted as needed to increase flexibility.

[0031] In this invention, the working principle of the device is as follows:

[0032] In use, depending on the type and size of the required spool 9, the guide roller 5 is moved to a suitable position, the thread 10 on the spool 9 is passed over the top of the guide roller 5 and embedded in the limiting groove 6, which limits its movement. Then, it passes under the conveyor wheel 303 and the tension roller 7, and finally passes over the guide roller 5 in the thread output direction, connecting the thread 10 to the quilting machine. Then, the drive motor 308 is started, which can drive the rotating rod 305 to rotate, and at the same time drive the transmission wheel 306 to rotate. Through the transmission belt 307, the transmission wheel 304 can be driven to rotate, and then the conveyor wheel 303 can be driven to rotate. Multiple conveyor wheels 303 can be driven to rotate synchronously at the same time to output the thread 10.

[0033] During the output of the production line 10, when it is necessary to adjust the tension of the production line 10, the knob 803 is turned to drive the screw 802 to rotate, thereby driving the movable plate 804 to move up and down, and causing the spring 805 and the connecting plate 806 to move up and down, which in turn drives the tension roller 7 to move up and down. When the tension roller 7 moves downward, it can squeeze the production line 10 to keep the production line 10 in a taut state. The spring 805 can compensate for this and prevent the production line 10 from breaking. Conversely, when the tension roller 7 moves upward, it can loosen the production line 10. The adjustment can be made as needed.
