specifically, as shown in fig. 1, 7 and 8, when the mechanism is used, first, when the debris on the aluminum alloy panel 1402 is too much or the magnetic chain plate 3 is jammed, so that the magnetic chain plate 3 is forced to stop and cannot normally rotate, the servo motor 13 starts to automatically increase the power and the current is increased, therefore, the torsion of the transmission bearing 1108 is increased, at this time, the butterfly spring piece 1106 senses that the current of the fixed shaft sleeve 1103 is increased, the ball 1107 starts to be absorbed, the ball 1107 is separated from the inside of the meshing groove 1105, the transmission bearing 1108 can not drive other parts to rotate through the clamping of the ball 1107 and the meshing groove 1105 when rotating, at this time, the transmission bearing 1108 alone rotates when the ball 1107 is separated from the meshing groove 1105, at this time, the gear plate 1101 stops rotating, at this time, the power of the servo motor 13 is reduced, thereby the conveyor has the overload protection function and avoids the damage of overload operation to the magnetic chain plate 3 and the servo motor 13;

the top end of the conveying area 1 is fixedly connected with a protective structure 14, the protective structure 14 comprises a fixture block 1401, an aluminum alloy panel 1402, a metal baffle 1403, a seal box 1404, a connecting groove 1405 and an arc angle 1406, the bottom end of the fixture block 1401 is fixed with the top end of the conveying area 1, the aluminum alloy panel 1402 is clamped on one side of the fixture block 1401, the metal baffle 1403 is fixed on both sides of the top end of the aluminum alloy panel 1402, the seal box 1404 is wrapped on the outer portion of the magnetic chain plate 3, the connecting grooves 1405 are arranged on both sides of the seal box 1404, the arc angle 1406 is arranged at the corner of the aluminum alloy panel 1402, the fixture block 1401 and the inner portion of the aluminum alloy panel 1402 are in a clamping structure, and the connecting;

specifically, as shown in fig. 1, 2 and 3, when this mechanism is used, first, a latch 1401 fixed to the tip of the conveyance section 1 is engaged to fix an aluminum alloy panel 1402 to the inside of the latch 1401, and metal stoppers 1403 are fixed to both sides of the aluminum alloy panel 1402, when the chips fall on the surface of the aluminum alloy panel 1402, the metal chips start to slowly move on the surface of the aluminum alloy panel 1402 due to the magnetic force of the magnetic link plate 3 and the magnetic strip 4, and the outer side of the magnetic chain plate 3 is wrapped with a layer of seal box 1404, and each part connected with the magnetic chain plate 3 enters the interior of the seal box 1404 through the connecting grooves 1405 arranged at the two sides of the seal box 1404, so that the interior of the seal box 1404 keeps a sealed environment, metal scraps cannot enter the interior of the magnetic chain plate 3, therefore, the magnetic transmission mechanism of the conveyor is protected in a sealing way, and metal debris is prevented from entering the transmission mechanism.

The working principle is as follows: when the multi-station magnetic conveyor is used, the external power supply of the multi-station magnetic conveyor is firstly dragged to the bottom end of a numerical control machine tool for generating metal scraps, the position is adjusted to ensure that the metal scraps can vertically fall on the surface of an aluminum alloy panel 1402, then the pneumatic telescopic rod 808 is started to lift the backing plate 807 and indirectly lift the conveyor, when the height is proper, the pneumatic telescopic rod 808 is stopped, the limiting block 805 is pressed to enable the limiting block 805 to leave from the inside of the limiting hole 806, then the inner pipe 801 is pulled out, the length is adjusted to enable the limiting block 805 to be clamped in the limiting hole 806, so that the falling area 7 is supported, then the magnetic conveyor is started, when the conveyor normally operates, the ball 1107 is clamped in the meshing groove 1105, at the moment, the servo motor 13 enables the transmission bearing 1108 to rotate through the transmission belt, the flange 1104 is driven to normally rotate through the ball 1107, the transmission rod 1102 in the flange 1104 normally rotates along with the normal rotation of the flange 1104, thereby driving the gear disc 1101, at the moment, the gear disc 1101 drives the magnetic chain plate 3 to continuously rotate, when the chips on the aluminum alloy panel 1402 are too much or the magnetic chain plate 3 is jammed, the magnetic chain plate 3 is forced to stop and cannot rotate normally, the servo motor 13 starts to automatically increase power and current, therefore, the torsion of the transmission bearing 1108 is increased, at this time, the butterfly spring piece 1106 senses that the current of the fixed shaft sleeve 1103 is increased, the ball 1107 starts to be absorbed, the ball 1107 is separated from the inside of the meshing groove 1105, the transmission bearing 1108 can not drive other parts to rotate through the clamping of the ball 1107 and the meshing groove 1105 when rotating, at this time, the transmission bearing 1108 alone rotates when the ball 1107 is separated from the meshing groove 1105, at this time, the gear plate 1101 stops rotating, at this time, the power of the servo motor 13 is reduced, thereby the conveyor has the overload protection function and avoids the damage of overload operation to the magnetic chain plate 3 and the servo motor 13;

secondly, the aluminum alloy panel 1402 is fixed on the inner side of the fixture block 1401 by the fixture block 1401 fixed at the top end of the conveying area 1 through clamping, the metal baffles 1403 are fixed on both sides of the aluminum alloy panel 1402, when chips fall on the surface of the aluminum alloy panel 1402, the metal chips start to slowly move on the surface of the aluminum alloy panel 1402 under the influence of the magnetic force of the magnetic chain plate 3 and the magnetic strip 4, due to the limitation of the metal baffles 1403, the metal chips cannot enter the inside of the conveyor through the gap between the conveying area 1 and the aluminum alloy panel 1402, when the metal chips are too fine, the metal chips possibly fall close to the inside of the conveyor, at this time, a layer of seal box 1404 is wrapped on the outer side of the magnetic chain plate 3, and all parts connected with the magnetic chain plate 3 enter the inside of the seal box 1405 through the connecting grooves arranged on both sides of the seal box 1404, so that the inside of the, the metal scraps cannot enter the magnetic chain plate 3, and arc-shaped angles 1406 are arranged at the corners of the aluminum alloy panel 1402, so that the metal scraps can pass through stably, the falling probability is reduced, and the magnetic transmission mechanism of the conveyor is protected in a sealing manner;

finally, after the magnetic chain plate 3 operates for a long time, the internal parts of the magnetic chain plate 3 are more easily loosened, so that the overall distance of the magnetic chain plate 3 begins to be elongated, at the moment, the automatic tensioning structure 5 is installed at the corner position of the magnetic chain plate 3, at the moment, the transmission gear 501 is meshed with a chain in the magnetic chain plate 3, so that the automatic tensioning structure 5 is fixed after the angle of the magnetic chain plate 3 deviates to a proper angle, when the magnetic chain plate 3 loosens, the length of the magnetic chain plate 3 is inevitably longer than before, at the moment, the stopper 505 generates a certain angle deviation through the connecting bearing 507 under the influence of the elastic force of the curved spring 509, so that the connecting block 504 fixed at the top end of the stopper 505 is subjected to the loosening angle deviation together, at the moment, the transmission gear 501 simultaneously generates deviation through the fixed bearing 503, the angle at the position of the magnetic chain plate 3 where the transmission gear 501 is meshed with the transmission, at this time, the larger the offset angle of the stopper 505 is, the more the transmission gear 501 presses down the corner position of the magnetic chain plate 3, so that the whole magnetic chain plate 3 is kept compact, and finally the magnetic conveying work of the multi-position magnetic conveyor is completed.
