Detailed implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-5 , the present invention provides a technical solution: a bead embroidery device alarm detection device, including a clip shaft 2, a passive clip 3, an active clip 4 and a contact member 5. The contact member 5 is fixedly installed on the passive clip 3 and the active clip 4. The passive clip 3 and the active clip 4 are sleeved on the outer surface of the clip shaft 2. The passive clip 3 and the active clip 4 are meshed with each other. The opening and closing of the passive clip 3 and the active clip 4 drive the contact and non-contact of the contact member 5. The contact member 5 outputs an electrical signal through a conductive signal to determine whether there is a bead between the active clip 4 and the passive clip 3.

[0022] A torsion spring 6 for driving the passive clip 3 and the active clip 4 to fit is arranged on the outer surface of the clip shaft 2. The fitting of the passive clip 3 and the active clip 4 makes the two groups of contact members 5 contact.

[0023] It also includes a drive mechanism 7 and a camshaft 1. The bottom of the camshaft 1 is fixedly connected to the output end of an external drive motor. The drive mechanism 7 is installed on the outer surface of the camshaft 1. The drive mechanism 7 is used to drive the passive clip 3 and the active clip 4 to open. The opening of the passive clip 3 and the active clip 4 drives the two groups of contact members 5 to separate.

[0024] Among them, the set torsion spring 6 can make the passive clip 3 and the active clip 4 always fit together. At this time, the two sets of contact members 5 provided can always fit and conduct electricity. Subsequently, the driving mechanism 7 drives the passive clip 3 and the active clip 4 to separate from each other, so that the beads located above the active clip 4 and the passive clip 3 fall from above the passive clip 3 and the active clip 4 to below the passive clip 3 and the active clip 4 along the bead threading wire. When the bead threading wire between the passive clip 3 and the active clip 4 is full of beads, beads will be clamped between the passive clip 3 and the active clip 4, so that the contact members 5 can be separated from each other. Through this method of turning on and off the power, and according to several consecutive power-off signals, false alarms of full beads of the passive clip 3 and the active clip 4 can be eliminated, so as to determine whether the bead threading wire below the passive clip 3 and the active clip 4 is in a full-bead state. Such a judgment method has a compact structure, is simple and reliable.

[0025] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , The passive clip 3 includes a passive clip body 8, a first clamping head 9 and a first gear 10. The outer surface of one set of the clip shafts 2 is rotatably connected to the passive clip body 8. One end of the passive clip body 8 is fixedly connected to the first clamping head 9. A first gear 10 is arranged on one side of the passive clip body 8. The active clip 4 includes an active clip body 11, a swing arm 12, a second clamping head 13 and a second gear 14. The outer surface of the other set of clip shafts 2 is rotatably connected to the active clip body 11. One end of the active clip body 11 is fixedly connected to the second clamping head 13. A swing arm 12 is obliquely arranged at the other end of the active clip body 11. A second gear 14 meshing with the first gear 10 is arranged on one side of the active clip body 11. Clamping grooves 15 for the external bead threading wire to pass through are provided on the opposite sides of the first clamping head 9 and the second clamping head 13.

[0026] Among them, driven by the torsion spring 6, the passive clip body 8 and the active clip body 11 always fit together. At this time, the bead threading wire for threading beads passes through the clamping groove 15, and the two sets of contact pieces 5 provided can be electrically connected through wires, so that the power-on effect can be achieved when the active clip 4 and the passive clip 3 are not threading beads. The first gear 10 and the second gear 14 provided can drive the passive clip body 8 to open synchronously when the active clip body 11 is driven to rotate, so that the column can fall through the opened first clamping head 9 and second clamping head 13 for threading.

[0027] Please refer to Figure 1 、 Figure 2 and Figure 5, the driving mechanism 7 includes a mounting base 16, a cam 17, and a roller 18. The mounting base 16 is fixedly installed on the outer surface of the camshaft 1. Cam 17s are fixedly connected to both sides of the mounting base 16. A roller 18 that contacts the swing arm 12 is rotatably connected to the bottom of the cam 17.

[0028] Among them, when bead threading is required, the camshaft 1 rotates driven by an external driving motor. At this time, the mounting base 16 and the roller 18 can be driven to rotate continuously. The rotating roller 18 can continuously contact the swing arm 12, so as to push the first clamping head 9 and the second clamping head 13 to open, achieving the effect of bead dropping and threading. When the roller 18 is disengaged from the swing arm 12, the torsion spring 6 can drive the first clamping head 9 and the second clamping head 13 to close again.

[0029] Please refer to Figure 5 , the diameter of the roller 18 is larger than that of the cam 17. The larger diameter of the roller 18 can prevent the cam 17 from directly contacting the swing arm 12 when the driving mechanism 7 pushes the active clip 4 to rotate.

[0030] During use, first, the torsion spring 6 provided causes the passive clip body 8 of the passive clip 3 and the active clip body 11 of the active clip 4 to rotate around the clip shaft 2. Through the meshing of the first gear 10 and the second gear 14, the contact member 5 is in conductive contact at this time, and the clamping grooves 15 of the first clamping head 9 and the second clamping head 13 are closed, and there are no beads on the bead threading wire in the clamping grooves 15. As the mounting base 16, the cam 17, and the roller 18 fixed on the camshaft 1 rotate, the driving mechanism 7 rotates as required. The roller 18 presses the swing arm 12 on the active clip 4, and the active clip body 11 rotates around the clip shaft 2. Through the meshing of the first gear 10 and the second gear 14, the contact member 5 is disengaged from conduction at this time, and the clamping groove 15 formed by the first clamping head 9 and the second clamping head 13 opens. The beads above the passive clip 3 and the active clip 4 fall along the bead threading wire. When the camshaft 1 rotates continuously, the clamping groove 15 is continuously opened and closed, and the contact member 5 conducts and cuts off electricity. If the beads that fall above the passive clip 3 and the active clip 4 are just clamped when the clamping groove 5 is closed, when the clamping groove 15 opens subsequently, the beads will surely fall along the bead threading wire. When the bead threading wire below the passive clip 3 and the active clip 4 is full of beads, the clamping groove 15 can never be closed, and the contact member 5 is disengaged and the electrical signal is disconnected. When the electrical signal of the device is disconnected continuously for several times, it can be confirmed that the bead threading wire below the passive clip 3 and the active clip 4 is indeed full, and the camshaft 1 stops rotating. This judgment method has a compact structure, is simple and reliable.

[0031] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
