[0030] Working principle: In operation, the pole piece is passed between the transmission rollers 3 and the transmission rollers 3 at both ends, and connected to the external transmission equipment, and then the laser die-cutting machine 1 is started to die-cut the pole ear of the pole piece, and the fan 10 is started at the same time, and the connecting pipe 11 and the connecting head 12 are used to generate suction, so that the debris generated during the die-cutting process is absorbed into the debris drawer 8 through the blanking chute 6, the air duct 4, and the dust head 5 for collection, so as to avoid the debris adhering to the pole piece and affecting the subsequent production quality of the pole ear. When the debris inside the debris drawer 8 is absorbed to a certain amount, it is only necessary to pull the pull ball 18 upwards to drive the slide rod 17 to drive the tooth block 19 to move upwards, and make the sub-magnet block 21 and the mother magnet block 22 magnetically fit together, and at the same time compress the spring 20 to release the restriction of the tooth block 19 on the tooth block plate 24. The handle block 25 is then slid along the inside of the arc groove 26 to drive the tooth block plate 24 to move around the fixed column 23, thereby releasing the restriction on the debris drawer 8 as a whole. The debris drawer 8 is then pulled out as a whole along the inside of the opening groove 7 to conveniently pour out the internal debris for cleaning. After cleaning, it is only necessary to reinsert the debris drawer 8 as a whole into the opening groove 7, and then push the handle block 25 around the arc groove 26 to reset the tooth block plate 24, and then press the pull ball 18 downward to release the magnetic attraction of the sub-magnet block 21 and the mother magnet block 22, and the tooth block 19 can be driven to mesh with the tooth block plate 24 under the action of the rebound force of the spring 20, so as to realize the limit fixation of the tooth block plate 24, thereby limiting the position of the debris drawer 8 as a whole.
