[0029] like Figure 1-4As shown, the utility model proposes an anti-thread-breakage device for an embroidery machine, comprising a box body 1 and a wire harness 8. A box door 2 is hinged on one side of the box body 1, and a handle 5 is fixedly installed on the box door 2. The staff can open the box door 2 through the handle 5 to inspect the inside of the box body 1. Thread tubes 4 are provided on both sides of the box body 1, and also include a first roller 10 and a second roller 11 rotatably installed in the box body 1.

[0030] In this embodiment, a fixing rod 9 is fixedly installed on the top of the inner wall of the box body 1, a first C-shaped plate 12 is fixedly installed on the bottom of the fixing rod 9, a first roller 10 is rotatably installed on both ends of the first C-shaped plate 12, the wire tube 4 includes an inlet tube 41 and an outlet tube 42, and the second roller 11 is arranged on the side of the first roller 10 close to the outlet tube 42.

[0031] Among them, one end of the wire harness 8 enters from the wire inlet tube 41 and passes through the rectangular frame 16, the wire harness 8 is wound on the first roller 10 and pressed against the top of the second roller 11, and the other end of the wire harness 8 passes through the wire outlet tube 42 and extends to the outside of the box 1. The second roller 11 is used to control the tension of the wire harness 8 and guide the direction of the wire harness 8 to ensure the smooth operation of the wire harness 8 and the quality of embroidery.

[0032] In this embodiment, a wire breakage detection device is provided on the top of the second roller 11, and the wire breakage detection device includes a mounting box 6 fixedly mounted on the top of the box body 1, and the wire breakage detection device also includes a moving rod 17 slidably mounted in the mounting box 6, and the moving rod 17 passes through one end of the box body 1 and is fixedly mounted with a second C-shaped plate 13, and the second roller 11 is rotatably mounted between the two ends of the second C-shaped plate 13, and a spring 21 is fixedly connected between the top of the box body 1 and the top bracket of the inner wall of the mounting box 6, and the spring 21 is sleeved on the outside of the moving rod 17. When the wiring harness 8 is broken, the wiring harness 8 originally pressed against the second roller 11 no longer generates a force on the second C-shaped plate 13, so that the moving rod fixedly connected to the second C-shaped plate 13 moves upward under the action of the spring 21.

[0033] Among them, the broken wire detection device also includes a fixed plate 18 fixedly installed on the moving rod 17, and two groups of guide rods 181 are fixedly installed on the fixed plate 18. The guide rods 181 are used to improve the stability of the fixed plate 18 when it moves. A baffle 19 is fixedly installed on one end of the guide rod 181 box 1, and the baffle 19 is used to limit the guide rod 181. A baffle 19 is fixedly installed on one side of the fixed plate 18, and an ultrasonic sensor 20 is fixedly installed on the top of the inner wall of the box 1. The ultrasonic sensor 20 is located directly above the baffle 19. An alarm light 7 is fixedly installed on the outer surface of the box 1. A controller 15 is also fixedly installed in the box 1. When the fixed plate 18 moves upward, it approaches the ultrasonic sensor 20. When the ultrasonic sensor 20 detects that the distance between the baffle 19 fixedly installed on one side of the fixed plate 18 and the ultrasonic sensor 20 is less than the set value, the ultrasonic sensor 20 transmits a signal to the controller 15.

[0034] In this embodiment, the storage assembly includes a storage slot 14 fixedly installed in the box body 1 and a rectangular frame 16 slidably installed in the storage slot 14. The storage assembly also includes an electric telescopic rod 22 fixedly installed in the storage slot 14. The rectangular frame 16 is fixedly installed at the telescopic end of the electric telescopic rod 22. Starting the electric telescopic rod 22 allows the rectangular frame 16 to move into the storage slot 14, which is convenient for the staff to quickly find the broken wire harness 8 during maintenance and prevent the broken wire harness 8 from flying around inside the machine. A pressure plate 23 is slidably installed in the rectangular frame 16. A wire passing ring 29 is fixedly installed on the top of the rectangular frame 16 on one side close to the first roller 10. The wire harness 8 passes through the wire passing ring 29, and the wire passing ring 29 can guide the direction of the wire harness 8. A tilting block 24 is fixedly installed on the bottom of the rectangular frame 16 on one side close to the wire inlet pipe 41. The tilting block 24 is used to reduce the friction when the wire harness 8 contacts the rectangular frame 16, thereby reducing the risk of the wire harness 8 breaking.

[0035] Among them, a rectangular groove 161 is opened on one side of the rectangular frame 16, and mounting plates 26 are fixedly installed on the top and bottom of the rectangular frame 16 near the rectangular groove 161. Screws 27 are rotatably installed between the mounting plates 26. A rotating motor 25 that drives the screw 27 to rotate is fixedly installed on one of the mounting plates 26. A T-shaped block 28 is threadedly connected to the screw 27. The T-shaped block 28 passes through the rectangular groove 161 and is fixedly connected to the pressure plate 23. The input end of the controller 15 is connected to the ultrasonic sensor 20, and the output end is connected to the alarm light 7 and the rotating motor 25. The start of the rotating motor 25 causes the screw 27 to rotate, so that the T-shaped block 28 is lifted and lowered, and the pressure plate 23 fixedly connected to the T-shaped block 28 is moved, and the broken wiring harness 8 is pressed between the pressure plate 23 and the rectangular frame 16, thereby fixing the broken wiring harness 8.

[0036] Working principle: During the working process of the utility model, when the wire harness 8 is broken, the wire harness 8 originally pressed against the second roller 11 no longer exerts a force on the second U-shaped plate 13, so that the moving rod fixedly connected to the second U-shaped plate 13 moves upward under the action of the spring 21, so that the fixed plate 18 fixedly installed on the moving rod 17 moves upward and approaches the ultrasonic sensor 20. When the ultrasonic sensor 20 detects that the distance between the baffle 19 fixedly installed on one side of the fixed plate 18 and the ultrasonic sensor 20 is less than the set value, the ultrasonic sensor 20 transmits a signal to the controller 15, and the controller 15 transmits the signal to the alarm light 7 and the rotating motor 25, so that the alarm light 7 alarms, which can The user is warned to prevent the embroidery machine from continuing to run when the wire harness 8 is broken, thereby reducing damage to the embroidery. At the same time, the start of the rotating motor 25 causes the screw rod 27 to rotate, so that the T-shaped block 28 threadedly connected to the screw rod 27 is lifted and lowered, so that the pressing plate 23 fixedly connected to the T-shaped block 28 is moved, and the broken wire harness 8 is pressed between the pressing plate 23 and the rectangular frame 16. The electric telescopic rod 22 is started to move the rectangular frame 16 into the storage groove 14, so that the staff can quickly find the broken wire harness 8 during maintenance, and avoid the broken wire harness 8 flying around inside the machine, thereby reducing the occurrence of the wire harness 8 being hinged into other parts, avoiding damage to the machine, and increasing the service life of the device.

[0037] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
