When the utility model is used, according to the bead embroidering process, the second driving structure of the switching mechanism 400 drives the corresponding bead guiding rod 200 to enter the bead feeding position to be matched with the bead feeding structure 100,

the clamping opening 104 of the clamping arm 122 of the bead feeding structure 100 is located at the bead taking station and is in an open state, and if the bead guiding rod provided with the bead swinging assembly is matched with the bead feeding structure 100, the first driver 109 of the bead swinging assembly drives the bead swinging piece 101 of the bead swinging assembly to enter the bead feeding station to be set as an origin. The beads on the bead swinging component 101 fall into a bead through the bead passing hole 102 on the bead guiding rod 200 under the self-weight or the pressure of the bead driving and pressing on the bead guiding rod 200 to abut against the substrate 120 in the clamping port 104, the first driver 109 drives the bead swinging component 101 of the bead swinging component to separate from the bead taking station, the beads are prevented from continuously falling into the clamping port 104, the bead feeding driving motor drives the conveying clamp component to convey the beads towards the bead embroidering station and under the embroidery needle, the clamping ports 124 of the two clamping arms 122 advance along with the driving plate of the conveying clamp component and then clamp and position the beads, and the beads are conveyed to the bead embroidering station by the embroidery needle. After embroidering beads, the bead feeding driving motor drives the conveying clamp assembly to retreat to the original point, the clamping ports 124 of the two clamping arms 122 retreat along with the retreating of the conveying clamp assembly and open to return to the original point to receive beads, and the first driver 109 drives the bead swinging piece 101 of the bead swinging assembly to enter a bead station to continue to convey the next bead.

When the beads fall from the bead swing part 101 through the bead through hole 102, the beads can be further positioned under the action of the positioning column 108, when the clamping arm 122 of the conveying assembly conveys the beads, the beads are separated from the positioning column 108 under the action of the separation structure, the positioning column 108 is pressed into the accommodating groove 126, and when the clamping arm 122 returns to the original point, the positioning column 108 is reset to the state of positioning the beads to be fallen.

In order to further accurately control the beads to fall one by one, after the bead swinging piece 101 slides down one bead, the bead swinging piece immediately enters a non-bead taking station, and the bead is stopped by a stop piece 104 combined with a stop structure at the non-bead taking station, so that the beads of the bead swinging piece 101 at the non-bead taking station are ensured not to fall through a hole. Referring to fig. 7-9, in this embodiment, when the ball oscillating element 101 moves towards the ball picking station, the coaxially mounted adapting arm 105 moves or synchronizes with the ball oscillating element 101 towards the ball picking station for a certain stroke (see fig. 7-9) under the action of the transmission elastic body, so as to be stable relative to the ball oscillating element 101, keep the ball stable in the ball passing hole 102 when the ball oscillating element 101 is moving, and when the ball oscillating element 101 enters the ball picking station, the limiting arm 106 of the limiting structure cooperates with the stopping arm 107 to control the adapting arm 105 to rotate continuously, and the adapting arm 105 is limited outside the ball picking station (see fig. 9).

If it is direct naked hang in sending pearl structure 100 lead pearl pole and sending pearl structure 100 to cooperate, send the centre gripping mouth 104 of the centre gripping arm 122 of pearl structure 100 to be located and get pearl station department, be in the open mode, the pearl on this leads pearl pole is under the effect of gravity or drive pressure, it contradicts on base plate 120 to fall into a pearl in centre gripping mouth 104, carry the clamp subassembly to send the pearl, send the pearl in-process, the pearl on this pearl pole is carried the clamp subassembly backstop and is no longer fallen the pearl, only centre gripping arm centre gripping mouth 124 gets back to the original point, unsettled pearl just can follow this pearl pole of leading and slide the pearl and fall the pearl to in the centre gripping mouth 124. Other bead feeding processes are consistent with the bead feeding process of the bead guide rod provided with the bead swinging assembly, and the bead feeding structure 100 continuously feeds and embroiders the beads in a reciprocating manner.
