[0023] The embroidery thread is sequentially passed through the first lead hole 4 and the second lead plate 7 and the second lead hole 8 on the first lead plate 3 to stretch the embroidery thread to the embroidery machine head. When subjected to the tension of the embroidery thread, one end of the movable plate 6 moves downward. During this process, the protrusion 10 on the movable plate 6 squeezes the first elastic spring 11, so that the first elastic spring 11 contacts the second elastic spring 12 downward. The first elastic spring 11 and the second elastic spring 12 are electrically connected. When the thread is broken, the tension of the embroidery thread is lost, and the elasticity of the first elastic spring 11 pushes the movable plate 6 back to its original position. At the same time, the first elastic spring 11 separates from the second elastic spring 12, so that the passage is disconnected. , thereby detecting the broken thread, during this process, the rotating shaft of the movable plate 6 drives the first connecting rod 13 to rotate, the first connecting rod 13 drives the third connecting rod 15 to rotate through the second connecting rod 14, the rotating shaft of the third connecting rod 15 drives the gear 16 to rotate, the gear 16 drives the rack 17 to move, the rack 17 pushes the sponge block 18 to extend between the first elastic spring 11 and the second elastic spring 12, cleans the dust and avoids the accumulation of dust, thereby solving the existing automatic broken thread detection embroidery machine. When using a mechanical automatic broken thread detection device, dust is easily generated due to the friction of the thread, which makes the mechanical contacts poorly contacted due to dust accumulation, thereby affecting the production problem.
[0024] Further, a mounting seat 19 is provided below the outer shell 2, a mounting groove 20 is provided on the top surface of the mounting seat 19, the mounting groove 20 is in a T-shaped structure, a connecting block 21 is inserted into the inner side of the mounting groove 20, the top surface of the connecting block 21 is fixedly connected to the bottom surface of the outer shell 2, the inside of the first threading groove 5 is connected to the inside of the first lead hole 4, the first threading groove 5 is in a V-shaped structure, the inside of the second threading groove 9 is connected to the inside of the second lead hole 8, and the second threading groove 9 is in a V-shaped structure;
[0025] When replacement is needed, the embroidery thread is passed through the first threading groove 5 and the second threading groove 9, thereby taking out the embroidery thread from the first lead hole 4 and the second lead hole 8, and then pulled out from the mounting seat 19, and then, the new one is inserted into the mounting groove 20 on the mounting seat 19, and the embroidery thread is passed through the first threading groove 5 and the second threading groove 9, thereby putting the embroidery thread from the first lead hole 4 and the second lead hole 8. The process is convenient and quick, and there is no need to re-thread the thread, which saves manpower and improves work efficiency.
[0026] Specific usage and function of this embodiment: The utility model sequentially passes the embroidery thread through the first lead hole 4, the second lead plate 7 and the second lead hole 8 on the first lead plate 3 to stretch the embroidery thread to the embroidery machine head. When the embroidery thread is subjected to tension, one end of the movable plate 6 moves downward. During this process, the protrusion 10 on the movable plate 6 squeezes the first elastic spring 11, so that the first elastic spring 11 contacts the second elastic spring 12 downward. The first elastic spring 11 and the second elastic spring 12 are electrically connected. When the thread is broken, the tension of the embroidery thread is lost, and the first elastic spring 11 is electrically connected to the second elastic spring 12. The elasticity of the reed 11 pushes the movable plate 6 back to its original position. At the same time, the first elastic reed 11 is separated from the second elastic reed 12, so that the passage is disconnected, thereby detecting the disconnection. In this process, the rotating shaft of the movable plate 6 drives the first connecting rod 13 to rotate, and the first connecting rod 13 drives the third connecting rod 15 to rotate through the second connecting rod 14. The rotating shaft of the third connecting rod 15 drives the gear 16 to rotate, and the gear 16 drives the rack 17 to move. The rack 17 pushes the sponge block 18 to extend between the first elastic reed 11 and the second elastic reed 12 to clean the dust and avoid dust accumulation.
[0027] When replacement is needed, the embroidery thread is passed through the first threading groove 5 and the second threading groove 9, thereby taking the embroidery thread out of the first lead hole 4 and the second lead hole 8, and then pulled out from the mounting seat 19, and then, the new one is inserted into the mounting groove 20 on the mounting seat 19, and the embroidery thread is passed through the first threading groove 5 and the second threading groove 9, thereby putting the embroidery thread into the first lead hole 4 and the second lead hole 8.
