[0047] The flushing assembly 4 includes: a water storage tank 41 provided on one side of the machine table 1, a pump body 42 provided on the top of the water storage tank 41, a spray head 43 communicated with the pump body 42 through a pipeline, and a bracket for installing the spray head 43; the bracket is installed on the top of the machine table 1; it is used to clean the polishing position when necessary.

[0048] A protective shell 11 is also installed on the top of the machine table 1. The protective shell 11 is used to prevent the debris generated during polishing from splashing everywhere and prevent dust from flying; a transparent window can be provided on the protective shell 11 to facilitate the operator to observe the polishing situation.

[0049] The collection and separation component 5 includes: a collection box 51 disposed below the machine table 1, a blanking port is provided on the machine table 1, and the blanking port communicates with the top of the collection box 51; an electromagnet 52 is installed below the blanking port, and the electromagnet 52 is connected to the collection box 51 through a mounting rod; the electromagnet 52 is in a conical shape, with the top of the cone facing upward and the bottom facing downward, and gradually inclining outward from top to bottom to facilitate the sliding of debris.

[0050] A collection plate 53 is disposed below the electromagnet 52, and the collection plate 53 is rotatably connected to the collection box 51; the collection plate 53 is composed of a magnetic attracting end 531 with magnetism and a non-magnetic abutting end 532; there are two collection plates 53, and one end of the two collection plates 53 close to each other is the magnetic attracting end 531, and the other end of the two plates away from each other is the abutting end 532; the magnetic attracting end 531 is made of a magnet, an electromagnet or a magnetizable metal material, so that when the electromagnet 52 is energized, it can attract the magnetic attracting end 531.

[0051] When the debris slides into the collection box 51 from the blanking port, the electromagnet 52 is used to adsorb large-particle metal debris, and the non-metal debris and some small-particle debris fall below with the air flow. At the same time, the electromagnet 52 attracts the magnetic attracting end 531 of the collection plate 53, so that the two collection plates 53 are connected to each other and present a closed state.

[0052] A rotating plate 54 is disposed below the abutting end 532 of the collection plate 53, the rotating plate 54 is rotatably installed in the collection box 51, the abutting end 532 abuts against the rotating plate 54, and the rotating shaft of the rotating plate 54 is located on one side close to the magnetic attracting end 531 of the collection plate 53; a filtering chamber 55 is provided at one end of the rotating plate 54 away from the collection plate 53, and a feeding port is opened at one end of the filtering chamber 55 close to the rotating plate 54; a feeding baffle 551 is rotatably installed on the feeding port, and the rotating shaft of the feeding baffle 551 is located at the top of the feeding port; a connecting member 541 is rotatably installed on the rotating plate 54, and the connecting member 541 is hinged to the feeding baffle 551; a rotating gap is left between the bottom of the feeding port and the rotating plate 54; a spring 557 is disposed in the rotating gap, and both ends of the spring 557 are connected to the filtering chamber 55 and the rotating plate 54 respectively.

[0053] When the electromagnet 52 is powered off, the large-particle metal debris adsorbed by the electromagnet 52 slides off the electromagnet 52 onto the collection plate 53. At the same time, due to the combined action of gravity and the spring 557, one end of the rotating plate 54 close to the collection plate 53 tilts upward, and the other end swings downward. During the downward swing of the rotating plate 54, the feeding baffle 551 is driven to swing through the connecting member 541, opening the feeding port. At this time, the non-metal debris and small-particle metal debris slide from the rotating plate 54 into the filtration chamber 55. During the downward swing of the rotating plate 54, the end in contact with the collection plate 53 drives the collection plate 53 to swing, forming a downward flow gap between the two collection plates 53, so that the large-particle metal debris sliding from the electromagnet 52 onto the collection plate 53 falls through the flow gap.

[0054] A nozzle 552 is also installed inside the filtration chamber 55, and the liquid outlet end of the pump body 42 is also communicated with the filtration chamber 55 through a pipeline. A bladder 553 and a microswitch 554 are also installed at the top inside the filtration chamber 55. The air outlet end of the bladder 553 is communicated with a piston tube 555, a piston 556 is slidably installed inside the piston tube 555, and the piston 556 is connected to the nozzle 552. When the feeding baffle 551 swings, it squeezes the bladder 553, then contacts the microswitch 554, and then the feeding baffle 551 continues to squeeze the bladder 553, and the piston 556 slides under pressure, driving the nozzle 552 to swing. The nozzle 552 is connected to an electromagnetic valve, and when it contacts the microswitch 554, the electromagnetic valve opens to spray water. A filter screen is also installed inside the filtration chamber 55 to filter other impurities insoluble in water, such as dust, abrasives, etc., and further adsorb small-particle metal debris.

[0055] As an alternative solution, the nozzle inside the filtration chamber 55 can be cancelled, and an exhaust fan is provided at the bottom of the filtration chamber 55. When the microswitch 554 is triggered, the exhaust fan is started to extract air.

[0056] Preferably, a pushing component is also provided on the machine table for pushing the debris to the discharge port. A cover plate is hinged to the discharge port. The cross-section of the cover plate is L-shaped, and the long side of the L-shape is used to close the discharge port, and a serrated structure is provided on its short side for cleaning the impurities on the surface of the cleaning brush.

[0057] The material pushing component 6 includes: a cleaning brush 61 and a power component for driving the cleaning brush 61 to move back and forth; the power component includes: a mounting plate 621 installed on the top of the collection box 51, a telescopic cylinder 622 installed on the top of the mounting plate 621, an L-shaped rotating block 623 hinged to the piston rod of the telescopic cylinder 622, an L-shaped limiting block 624 hinged to the middle of the L-shaped rotating block 623, one end of the horizontal part of the L-shaped rotating block 623 is connected with a connecting rod 625, both ends of the connecting rod 625 are respectively connected with the cleaning brush 61 and the L-shaped rotating block 623, a sliding rod 626 is connected to the side of the L-shaped limiting block 624 away from the cleaning brush 61, and a connecting seat 627 is also installed on the mounting plate 621. A chute is opened in the connecting seat 627, and the chute is slidably connected with the sliding rod 626; a torsion spring is connected to the rotating shaft of the L-shaped limiting block 624; when the piston rod of the telescopic cylinder 622 extends, it drives the L-shaped rotating block 623 to move towards the cover plate 12. At this time, the horizontal part of the L-shaped limiting block 624 abuts against the bottom of the sliding rod 626, so that the cleaning brush 61 moves horizontally towards the cover plate 12, thereby cleaning the surface of the cover plate 12; when the piston rod of the telescopic cylinder 622 retracts, it first drives the L-shaped rotating block 623 to retract, thereby driving the cleaning brush 61 to retract. When the cleaning brush 61 retracts, it contacts the serrated structure to clean the cleaning brush 61. At this time, due to the action of the torsion spring, the cleaning brush 61 will not rotate upwards or may rotate slightly upwards, which does not affect the cleaning effect of the cleaning brush 61. Then when the sliding rod 626 abuts against the bottom of the chute, the piston rod drives the L-shaped rotating block 623 and the L-shaped limiting block 624 to rotate along the rotating shaft of the L-shaped limiting block 624, thereby driving the cleaning brush 61 to rotate upwards while moving away from the workbench.
