color changing: when the embroidery machine mainboard sends out B color embroidery pearl signal, the embroidery pearl control panel controls the color changing motor to change color in forward rotation, and when the A color pearl needs to be changed, the embroidery pearl control panel controls the color changing motor to change color in reverse rotation.

The color changing button is arranged corresponding to the color changing function, the button mainly controls the color changing motor, the color changing motor can rotate by a certain angle to drive the color changing slide block connected with the color changing motor under the manual state, the point A corresponds to the position of the bead under the color bead, the point B corresponds to the position of the bead under the color bead, when the color changing button is pressed again, the color changing motor can rotate back to the original position in the opposite direction, the color changing slide block moves back to the point A from the point B, the point A corresponds to the color bead, and the point B corresponds to the color bead under the color changing button under the manual state.

After the device is turned on, the bead is first positioned to ensure that the beads falling from the bead-dropping device are clamped by the bead clamper.

The locating means that the bead feeding motor is controlled, after the bead feeding motor is powered on, the bead feeding motor rotates towards a certain direction, the bead clamping device is pulled to the bead hole position (shown in figure 2), a bead is received, the bead feeding motor rotates towards the opposite direction, the bead clamping device clamps the bead, the bead is sent to the bottom plate opening (shown in figure 3), and therefore the bead locating is powered on.

In order to control the position finding function, a position finding key is arranged, and the key mainly completes 3 functions of the bead feeding motor.

(1) When the bead clamping device clamps beads at the opening of the bottom plate for waiting, the bead searching button is pressed, the bead feeding motor can continue to rotate to send the beads out of the bottom plate (as shown in figure 4), and the bead feeding motor is locked at the moment, so that an operator can conveniently align the needle.

(2) At this moment, when the position finding key is pressed for the second time, the bead feeding motor rotates reversely, the bead clamping device is pulled back to the bead hole position and the bead feeding motor is locked, at this moment, an operator can observe whether beads in the bead hole can smoothly fall into the bead clamping device or not, the bead clamping device is convenient to clamp the beads, if the beads cannot be clamped, the locking screw of the bead feeding swing rod is loosened to adjust the positions of the bead clamping device and the bead hole, and the beads are locked after being adjusted (as shown in fig. 2).

(3) When the position-finding key is pressed for the third time, the bead-feeding motor clamps the beads by the bead-clamping device and sends the beads to the position of the bottom plate opening, and the half-flow lock waits for the next work instruction!

According to the bead blockage detection method, the positive and negative rotation X degrees of the bead discharging motor need to be controlled, so that the inching button is arranged to inching control the bead discharging motor.

B, inching: the main control B motor (pearl motor under the B colour pearl) clockwise rotation 15 degrees, will descend pearl response to press from both sides and open, counter-clockwise rotation comes back to the normal position again, detect this moment lower pearl response press from both sides, press from both sides whether pearl or lower pearl steel wire, if lower pearl response presss from both sides, press from both sides the pearl, the B motor just stops not rotating at the normal position, wait for next instruction, if lower pearl response clamp, press from both sides be lower pearl steel wire, no detected pearl, the B motor just rotates, dial the pearl in the pearl memory down on lower pearl steel wire, again by the downward transmission of clip one-level, when lower pearl response presss from both sides and detects to press from both sides the pearl, lower pearl motor rotates to, next received signal, the reversal 15 degrees, can open lower pearl response clamp, corotation returns the position that the normal rotation can let lower pearl response press from both sides the complete closure, stall, wait for next signal.

A, inching: the principle of the inching of A and the principle of the inching of B are the same, namely the inching of A is controlled by the motor of A (a bead-under-A motor), and the rotating direction of the motor of A and the rotating direction of the motor of B are controlled by the inching of A to be just opposite.

In addition, a lifting key is also arranged and mainly used for controlling the pearl embroidery machine, the device can be lifted by the air cylinder when the lifting key is pressed in a manual state, and the device can be lowered by the air cylinder when the lifting key is pressed again.
