As shown in fig. 5, driven gears 216 are fixedly mounted on the driving rods 2141 of the two feeding mechanisms 210, wherein one driven gear 216 is in belt transmission connection with the forward rotation one-way driving wheel 232, and the other driven gear 216 is in belt transmission connection with the reverse rotation one-way driving wheel 233. In addition, the forward rotation one-way driving wheel 232/reverse rotation one-way driving wheel 233 may also be connected to the driving rod 2141 through a gear 2322 or a chain transmission.

The working principle is as follows:

the power element 220 is activated to drive the driving shaft 231 to rotate, and the driving shaft 231 rotates to drive the stirring paddle 2121 to rotate, so as to stir the embroidery beads in the material cup 212, so that the embroidery beads can enter the bead guiding rod 2122.

When the power element 220 rotates forward, the driving shaft 231 drives the flywheel seat 2321 on the forward rotation one-way driving wheel 232 and the reverse rotation one-way driving wheel 233 to rotate, and the flywheel seat 2321 rotates to drive the pawl 23231 to rotate around the axis of the flywheel seat 2321. Since the directions of the pawls 23231 of the forward unidirectional driving wheel 232 and the reverse unidirectional driving wheel 233 are opposite, the pawl 23231 of the forward unidirectional driving wheel 232 drives the ratchet structure 23233 to rotate together, and the pawl 23231 of the reverse unidirectional driving wheel 233 does not drive the ratchet structure 23233 to rotate. The ratchet gear 23233 is integrally formed with the gear 2322, so that the gear 2322 of the forward rotation one-way driving wheel 232 rotates therewith, and thus rotates with the corresponding driven gear 216.

The driven gear 216 drives the driving rod 2141 and the eccentric cam 2142 on the driving rod 2141 to rotate, the eccentric cam 2142 pushes the shift rod 2152 in the rotation process, so that the half-gear clamping jaw 2151 rotates, the clamping head 215 is opened at the moment, the embroidery bead can pass through the clamping head 215, the eccentric cam 2142 is separated from the shift rod 2152, the half-gear clamping jaw 2151 resets under the reset spring 2154, and the clamping head 215 closes to clamp the bead guide rod 2122 at the moment.

A second bead channel 3241 is disposed on the guiding fixing seat 324 in a penetrating manner, and a gap communicated with the second bead channel 3241 is also disposed on the guiding fixing seat 324.

The working principle is as follows:

when the bead guide device is used, four bead guide rods 2122 need to be placed into two first bead guide channels 32311 and two second bead guide channels 3241 through gaps, beads slide from the four bead guide rods 2122 and enter the first bead guide channels 32311 and the second bead guide channels 3241, the first bead guide channels 32311 are blocked by bead clamping rods 32321 in the first bead guide channels 32311 for limiting, and the beads in the second bead guide channels 3241 are contacted with the upper part of the bead tube pressing sheet 32122 for limiting.

When the embroidery bead clamping jaws 32123 need to clamp an embroidery bead on one of the first embroidery bead channels 32311, the driving element 322 controls the swing rod 3221 to drive the corresponding trolley 3212 to move, so that the embroidery bead clamping jaws 32123 move from the outside of the base 3211 to the position below the first embroidery bead channel 32311, in the process, the swing shaft 32124 drives the trolley 32121 to move, at this time, under the interference of the damping member 32112, the bead pressing piece 32122 is interfered and cannot move, so that the relative movement between the embroidery bead clamping jaws 32123 and the shifting post 32125 causes the embroidery bead clamping jaws 32123 to open, and the embroidery bead on the embroidery bead clamping jaws 32123 drops to complete feeding operation after the embroidery bead clamping jaws 32123 are unfolded.

After the shifting post 32125 moves to one end of the guiding groove 32129, the cart 32121 and the bead pressing plate 32122 cannot move relatively, so that the bead clamping jaws 32123 and the bead pressing plate 32122 move together with the cart 32121 until the bead clamping jaws 32123 are located below the first bead channel 32311.

Then the control element 3233 controls the bead clamping cam 32331 to rotate by a certain angle and then return to the initial position, in the process, the bead clamping cam 32331 is separated after contacting with the corresponding lifting and pressing rod 32322, the lifting and pressing rod 32322 is poked to control the bead clamping rod 32321 to swing during the contact, the lifting and pressing rod 32322 is separated from the bead clamping cam 32331 and then returns under the action of the pre-tightening spring 325, and at the moment, one bead falls onto the bead clamping jaw 32123 from the first bead channel 32311.

At this time, the swing rod 3221 pushes the trolley 3212 to move the embroidery bead clamping jaw 32123 out of the base 3211. In the process, the swing shaft 32124 drives the cart 32121 to move, and at this time, the bead pressing piece 32122 is interfered by the damping piece 32112 and cannot move, so that the bead clamping jaws 32123 and the shifting post 32125 move relatively to each other to close the bead clamping jaws 32123 and clamp the beads.

When the end of the cart 32121 contacts the bead pressing plate 32122, the bead pressing plate 32122 is driven to move together until the bead clamping jaw 32123 moves out of the base 3211 to enter a feeding state.

When the embroidery bead clamping jaws 32123 need to clamp an embroidery bead on the second embroidery bead channel 3241 on the same sliding rail 32111, the embroidery bead clamping jaws 32123 are moved to the position below the second embroidery bead channel 3241, and then the embroidery bead clamping jaws 32123 are moved to the outside of the base 3211.

When the embroidery beads in the first embroidery bead channel 32311 and the second embroidery bead channel 3241 on the other sliding rail 32111 are needed to be used, the swinging shafts 32124 on the two trolleys 3212 are kept coaxially arranged, and then the reversing element 330 is started to drive the base 3211 to translate, so that one swinging shaft 32124 is separated from the swinging rod 3221 and enters the guide fixing seat 324, and the other swinging shaft 32124 is moved out of the guide fixing seat 324 to be abutted to the swinging rod 3221.
