[0032] Working principle: When it is necessary to supply the heart-shaped button 401, first pull up the movable frame 501. At this time, the movable frame 501 will drive the grooved rod 505 to move outward. Then insert one end of the button tube 4 into the placement seat 3, and release the movable frame 501. Under the action of the spring B503, drive the movable frame 501 to move downward, so that the pressing plate 504 on the movable frame 501 presses into the button tube 4. At this time, it will contact and squeeze the positioning rod 402, so that the positioning rod 402 retracts to release the limit on the heart-shaped button 401, so that the bottom heart-shaped button 401 can fall into the heart-shaped groove 601 on the blanking seat 6. At the same time, the movable frame 501 will drive the grooved rod 505 to reset, so that the insertion rod 506 at the bottom of the grooved rod 505 is inserted into the clamping sleeve 404 to fix the button tube 4; Then use the hydraulic cylinder 201 to drive the connected moving frame 602 to move, so that the blanking seat 6 moves, so that the blanking seat 6 drives the heart-shaped button 401 to move above the button seat 104, so that the heart-shaped button 401 can fall into the button seat 104; At the same time, when the blanking seat 6 moves, it will drive the transmission rack 603 to move, so that the transmission rack 603 can drive the tooth disc 706 connected to the transmission wheel 707 to rotate, so that the tooth disc 706 drives the L-shaped rod 704 connected to the adjusting wheel 705 to rotate. At this time, the L-shaped rod 704 will rotate in the chute block 703, thereby driving the knocking rod 702 connected in the chute block 703 to swing reciprocally, so that its two ends respectively knock on the placement seat 3 and the button seat 104, so that the heart-shaped button 401 can accurately fall into the button seat 104; Then when the blanking seat 6 retracts, the transmission tooth 604 on the moving frame 602 will drive the one-way wheel 802 to rotate under the action of the tension spring 605, so that the one-way wheel 802 drives the driving wheel 803 connected to the universal joint 801 to rotate, so that the driving wheel 803 drives the belt wheel 102 connected to the driven wheel 103 to rotate, driving the button seat 104 on the conveyor belt 101 to move to supply the heart-shaped button 401.
