The toothed plate moves through the gear, the shaft, and the round rod to drive the circular magnetic block 1 to rotate 180°. The circular magnetic block 1 rotates 180°, so that the magnetism of the circular magnetic block 2 is converted from attraction to repulsion, thereby driving the movable plate to move away from the fixed plate, thereby increasing the gap between the two parts after cutting, which is convenient for better cleaning of the debris originally located in the gap.

[0032] The following points are worth noting:

[0033] 1. The telescopic structure is composed of a cylinder 8 and a telescopic rod 6. The cylinder 8 is fixedly mounted on the upper surface of the mounting plate 5. The telescopic rod 6 is mounted on the cylinder 8, and the upper end of the telescopic rod 6 is fixedly connected to the lower surface of the cross bar 7.

[0034] 2. The telescopic structure is arranged so that the height of the cross bar 7 can be adjusted in the vertical direction to meet the use requirements.

[0035] 3. A stopper 11 and a stopper 12 are fixedly mounted on the cross bar 7 and matched with the movable plate 10 . The match between the stopper 11 and the stopper 12 can limit and block the movable plate 10 slidably mounted on the cross bar 7 .

[0036] 4. The supporting structure consists of a fixed block 13, a supporting plate 14, a mounting groove 16 and a magnetic block 17. Two fixed blocks 13 are fixedly installed on both sides of the cutting table 1, and a supporting plate 14 is fixedly installed on the lower ends of the two corresponding fixed blocks 13, and the aggregate seat 15 is placed on the corresponding support plate 14. A mounting groove 16 is provided on one side of the four fixed blocks 13 close to the aggregate seat 15 and on one side of the aggregate seat 15 close to the fixed block 13. A magnetic block 17 is fixedly installed in each of the eight mounting grooves 16, and the magnetism of the two corresponding magnetic blocks 17 on the sides close to each other is opposite.

[0037] 5. The support structure is provided to facilitate the placement of the material collecting seat 15 on the support plate 14. At the same time, the magnetic cooperation (attraction) of the two corresponding magnetic blocks 17 is utilized to make the placement of the material collecting seat 15 on the support plate 14 more stable.

[0038] Reference Figure 1 , Figure 4 as well as Figure 6 , a vertical rod 20 is installed on both sides of the mounting plate 5 through a sliding assembly, a strip scraper 21 is fixedly installed at the lower ends of the two vertical rods 20, a cleaning block 24 is fixedly installed on the lower surface of the strip scraper 21, two mounting grooves 22 matching with the strip scraper 21 are opened on the cutting table 1, and the mounting grooves 22 are connected with the sliding groove 2, and two slag dropping holes 23 matching with the aggregate seat 15 are opened on the cutting table 1, and the slag dropping holes 23 are connected with the corresponding mounting grooves 22;

[0039] The following points are worth noting:

[0040] 1. The sliding assembly is composed of a sliding support groove 18 and a sliding support block 19. A sliding support groove 18 is provided on both sides of the mounting plate 5. A sliding support block 19 is slidably installed in each of the two sliding support grooves 18, and the ends of the two sliding support blocks 19 that are away from each other are fixedly connected to the second vertical rod 20.

[0041] 2. The setting of the sliding assembly enables the second vertical rod 20 to slide only in a direction parallel to the mounting plate 5, and the two will not have relative movement in the vertical direction.

[0042] 3. Two stoppers 30 cooperating with the strip scraper 21 are fixedly installed on the inner walls of the two slag dropping holes 23; the setting of the stoppers 30 limits the movement of the strip scraper 21, so that the impurities scraped away can smoothly pass through the slag dropping holes 23 and fall into the aggregate seat 15.

[0043] Reference Figure 1 as well as Figure 2-5 A movable structure is provided between the two upright poles 1 4 and the two upright poles 20;

[0044] A stepped hole 40 is provided on the fixed plate 9, a rotating shaft 36 is rotatably mounted on the stepped hole 40, a horizontal moving structure is installed between the fixed plate 9 and the rotating shaft 36, and a magnetic structure is installed between the rotating shaft 36 and the movable plate 10;

[0045] The following points are worth noting:

[0046] 1. The moving structure consists of a threaded hole, a threaded rod 25, a rotating rod 26, a second magnetic block 27, a third magnetic block 28 and a knob 29. A threaded hole is provided on each of the two vertical rods 4. A threaded rod 25 is threadedly installed on the two threaded holes. A knob 29 is fixedly installed at both ends of the threaded rod 25. Two rotating rods 26 are fixedly installed on the threaded rod 25. A second magnetic block 27 is fixedly installed at both ends of the two rotating rods 26. The magnetism of the two second magnetic blocks 27 on the same side is opposite. A third magnetic block 28 is fixedly installed on each of the two vertical rods 20. The magnetism of the two corresponding magnetic blocks 27 on the adjacent sides of the vertical rod 20 is the same.

[0047] 2. The horizontal moving structure is composed of a step slider 33, a step chute 34, a tooth plate 35 and a gear 37. A step slider 33 is provided on the side of the fixed plate 9 away from the movable plate 10. Two step chute 34 are slidably mounted on the step slider 33. A tooth plate 35 is fixedly mounted at one end of the two step chute 34. A gear 37 meshing with the tooth plate 35 is fixedly mounted on the rotating shaft 36.

[0048] 3. A magnetic block 2 39 is fixedly installed at both ends of the tooth plate 35 through a rod body 38. Two vertical poles 31 of different heights are fixedly installed on the cutting table 1. A magnetic block 1 32 matching with the magnetic block 2 39 is fixedly installed at the upper ends of the two vertical poles 31.

[0049] 4. Two vertical poles 31 of different heights are set, so that the heights of the two magnetic blocks 1 32 are different. When the magnetic block 1 32 at the lowest position cooperates with the magnetic block 2 39, the tooth plate 35 is driven to move, thereby moving the movable plate 10. When the magnetic block 1 32 at the higher position cooperates with the other magnetic block 2 39, the movable plate 10 can also be driven to move (from far to near, back to Figure 1 shown).

[0050] 5. The magnetic structure consists of a circular groove body, a groove body, a circular magnetic block 1 41 and a circular magnetic block 2 42. A circular groove body connected to the stepped hole 40 is opened on the side of the fixed plate 9 close to the movable plate 10. One end of the rotating shaft 36 is located in the circular groove body and two round rods are fixedly installed. A circular magnetic block 1 41 is fixedly installed at both ends of the two round rods (not marked in the figure). The magnetism of the two circular magnetic blocks 1 41 close to the movable plate 10 is opposite. Two groove bodies are opened on the side of the movable plate 10 close to the fixed plate 9. A circular magnetic block 2 42 is fixedly installed in each of the two groove bodies. The magnetism of the two circular magnetic blocks 2 42 on the same side is opposite.

[0051] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0052] In the present invention, when the workpiece after cutting moves to the right below the mounting plate 5, it stops moving, and then the cylinder 8 is turned on. The cylinder 8 drives the cross bar 7 to move downward through the telescopic rod 6. The cross bar 7 moves downward so that the lower surfaces of the fixed plate 9 and the movable plate 10 are pressed against the workpiece. The fixed plate 9 and the movable plate 10 are respectively located on both sides of the cutting opening.

[0053] During the above process, when the magnetic block 2 39 moves to the lowest position, the corresponding magnetic block 1 32 has a magnetic effect on it (attraction or repulsion is possible, attraction means that the magnetic properties of the same side 32 and the magnetic block 2 39 are opposite, and repulsion means that the magnetic properties of the magnetic block 1 32 and the magnetic block 2 39 are the same), so that it drives the tooth plate 35 to slide horizontally relative to the fixed plate 9;

[0054] The toothed plate 35 moves through the gear 37 to drive the rotating shaft 36 to rotate 180°. The rotating shaft 36 rotates 180° and drives the two circular magnetic blocks 41 to rotate 180° through the round rod. The two circular magnetic blocks 41 rotate 180°, so that the magnetic field of the circular magnetic block 42 is converted from attraction to repulsion, thereby driving the moving plate 10 to move in a direction away from the fixed plate 9. The movement of the moving plate 10 can drive the cut part of the workpiece to move a certain distance (so that the distance between the two parts after cutting is increased);

[0055] A rotational force is applied to the knob 29 by hand, so that the circular knob 29 that is not in contact with the vertical rod 4 rotates and contacts with the vertical rod 4. In this process, the rotating rod 26 rotates together with the threaded rod 25. The rotation of the rotating rod 26 drives the magnetic block 27 to rotate 180°, thereby changing the magnetism of the magnetic block 3 28 (the originally attractive side turns into repulsive side, and the originally repulsive side turns into attractive side), so that the magnetic block 3 28 is forced to move. The movement of the magnetic block 3 28 drives the strip scraper 21 and the cleaning block 24 to move through the vertical rod 20. The strip scraper 21 contacts the upper surface of the workpiece and can scrape and clean the debris on the upper surface of the workpiece. The cleaning block 24 is located between the two parts after cutting, and cleans the impurities remaining in the gap between the two parts. At the same time, the two side edges of the cleaning block 24 contact the two parts after cutting the workpiece through the elastic pad, thereby also having a cleaning effect on the side edges of the two parts.
