[0047] The lifting electric push rod 133 connected to the first mounting plate 134 drives the first mounting plate 134 to move up, and then drives the two slides to move through the transverse screw rod slide rod 31, so that the second mounting plate 135 is located directly above the calibration base 11, and then the lifting electric push rod 133 connected to the second mounting plate 135 drives the second mounting plate 135 to move down, and then the transmission member 6 on the second mounting plate 135 drives the two collecting boxes 23 to collide again, and then the two-way electric push rod 54 works to drive the two cleaning rods 53 to move relative to each other, and then the brushes 531 of the two cleaning rods 53 can collide to The second motor 51 then drives the turntable 52 to rotate, and the turntable 52 drives the two cleaning rods 53 to rotate, and the brush 531 can rotate around the calibration piece 12, and the brush 531 can clean the waste, and the cleaned waste can fall into the feed trough. In this process, the transmission cylinder 551 also rotates synchronously with the cleaning rod 53, and the transmission cylinder 551 drives the transmission rod 554 and the arc-shaped limit block 555 to rotate synchronously, and the arc-shaped limit block 555 can gradually contact the second arc-shaped convex head 561, and the second arc-shaped convex head 561 contacts the arc-shaped limit block 55 5 applies extrusion force, so that the arc-shaped limit block 555 can move, the arc-shaped limit block 555 drives the transmission rod 554 to move, the transmission rod 554 drives the piston 553 to move forward in the transmission cylinder 551, and the piston 553 applies extrusion force to the inside of the transmission cylinder 551. Due to the effects of the outlet check valve 557 and the inlet check valve, the extrusion force can squeeze the internal air of the transmission cylinder 551 into the outlet channel 532, and then spray out from the air nozzle 552. The sprayed air can act on the outer wall of the calibration piece 12, and the waste materials that are still connected can be more easily removed by the sprayed air. After the calibration part 12 is separated, when the arc limit block 555 gradually separates from the second arc protrusion 561, the elastic force of the third spring 556 can drive the arc limit block 555 to reset, and the arc limit block 555 drives the transmission rod 554 and the piston 553 to move synchronously. The piston 553 applies a pulling force to the inside of the transmission cylinder 551. Due to the action of the exhaust check valve 557 and the intake check valve, the pulling force can draw external air into the transmission cylinder 551 through the intake pipe 558. In this cycle, the air nozzle 552 can continuously spray gas, thereby improving the effect of cleaning the calibration part 12.
