[0021] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 7 The embodiments are described in detail below.

[0022] This embodiment provides a slag removal and splash prevention mechanism for laser cutting of alloy plates, as shown in the attached diagram. Figures 1-7 As shown, the machine tool includes a machine tool body 1. Inside the machine tool body 1, at the top, there is a sword-shaped plate 2 for supporting the alloy plate. Both ends of the sword-shaped plate 2 are fixedly connected to gear shafts 3. The top and bottom ends of the sword-shaped plate 2 are symmetrical sawtooth structures. There are several sword-shaped plates 2, which are arranged parallel to each other and are equidistantly rotatably connected inside the machine tool body 1 by the gear shafts 3 on both sides. When two adjacent sword-shaped plates 2 are in a vertical state, the distance between them is greater than the rotation diameter of the sword-shaped plate 2, which can ensure that each sword-shaped plate 2 is not restricted when rotating.

[0023] The machine tool body 1 is internally equipped with a flipping mechanism that can flip the sword guard plate 2. The flipping mechanism includes a rack frame 6 and two first electric push rods 7. The movable rod parts of the two first electric push rods 7 are respectively connected to both sides of the rack frame 6, and the fixed rod parts of the two first electric push rods 7 are fixedly connected to the side of the machine tool body 1. The machine tool body 1 has a cavity inside for placing the rack frame 6 and the gear shaft 3. The gear shafts 3 at both ends of the rack frame 6 and the sword guard plate 2 are inserted through it. Inside the cavity of the machine tool body 1, the rack frame 6 is engaged with the bottom of the gear shaft 3. The gear shafts 3 at both ends of several sword plates 2 are engaged with the rack frame 6. The rack frame 6 is horizontally arranged inside the cavity of the machine tool body 1 and its lower surface abuts against the inner bottom wall of the cavity. The rack frame 6 is engaged with the bottom of multiple gear shafts 3, so that the rack frame 6 can only move laterally in the horizontal direction, thereby ensuring that when the first electric push rod 7 drives the rack frame 6 to move laterally and reciprocating, it can always drive multiple sword plates 2 to rotate synchronously.

[0024] The bottom end inside the machine tool body 1 is provided with a first transverse driving mechanism, and the movable end of the first transverse driving mechanism is provided with a first movable frame 4. The first transverse driving mechanism comprises a first driving motor 8, a bevel gear rotating rod 9 and two first threaded lead screws 10. The bevel gear rotating rod 9 is connected to the output end of the first driving motor 8 through a spline and is rotatably connected to the bottom end inside the machine tool body 1. The first driving motor 8 is fixedly installed on the bottom of the side surface of the machine tool body 1. The two first threaded lead screws 10 are each fixedly connected with a bevel gear at one end close to the bevel gear rotating rod 9. The two first threaded lead screws 10 are rotatably connected to the two sides of the bottom end inside the machine tool body 1 through the bevel gears at the two ends of the bevel gear rotating rod 9. The bevel gear rotating rod 9 and the two first threaded lead screws 10 are each sleeved with a support block for supporting. The support block is fixedly connected to the inner bottom wall of the machine tool body 1, so as to limit and support the bevel gear rotating rod 9 and the first threaded lead screws 10, and ensure that the bevel gear rotating rod 9 is always in driving connection with the two first threaded lead screws 10. The two ends of the first movable frame 4 are rotatably connected to the outer sides of the two first threaded lead screws 10 through internal threads.

[0025] When the first driving motor 8 drives the bevel gear rotating rod 9 to rotate clockwise or counterclockwise, the two first threaded lead screws 10 can be driven by the bevel gears to rotate synchronously counterclockwise or clockwise, so as to drive the first movable frame 4 to move transversely back and forth through threads, thereby adjusting the transverse position of the slag removing mechanism perpendicular to the sword grid plate 2, so that the slag removing mechanism can correspond to different sword grid plates 2.

[0026] The first movable frame 4 is provided with a second transverse driving mechanism, and the movable end of the second transverse driving mechanism is provided with a second movable frame 5. The second transverse driving mechanism comprises a second driving motor 11 and a second threaded lead screw 12. The second threaded lead screw 12 is connected to the output end of the second driving motor 11 through a spline and is rotatably connected to the inside of the first movable frame 4. The second driving motor 11 is fixedly installed on the side surface of the first movable frame 4. A limiting rod 13 is fixedly connected to the bottom end inside the first movable frame 4 and is arranged below and corresponds to the second threaded lead screw 12. The limiting rod 13 can limit the second movable frame 5, so that it can only move along the direction of the limiting rod 13. The second movable frame 5 is rotatably connected to the outside of the second threaded lead screw 12 through internal threads and is sleeved on the outside of the limiting rod 13. When the second driving motor 11 drives the second threaded lead screw 12 to rotate clockwise or counterclockwise, the second movable frame 5 can be driven to move back and forth along the direction of the limiting rod 13, thereby adjusting the horizontal position of the slag removing mechanism parallel to the sword grid plate 2, so as to facilitate the slag removing mechanism to remove slag from different parts of the sword grid plate 2. The moving direction of the second movable frame 5 is perpendicular to the moving direction of the first movable frame 4. The two directions are perpendicular to each other, and the two directions can cooperate to adjust the slag removing mechanism to any part below the sword grid plate 2.

[0027] The top of the second movable frame 5 is equipped with a slag removal mechanism for cleaning the slag on both sides of the sword grid plate 2. The slag removal mechanism includes a second electric push rod 14, a fixed frame 15, a dual-axis motor 16, and a slag cleaning disc 17. The second electric push rod 14 is fixedly installed on both sides of the second movable frame 5, and the movable parts of the two second electric push rods 14 pass through the top of the upper surface of the second movable frame 5 and are fixedly connected to the fixed frame 15. The movable parts of the two second electric push rods 14 move synchronously, allowing adjustment of the height of the slag cleaning disc 17 to facilitate contact between the slag cleaning disc 17 and the sword grid plate 2. The dual-axis motor 16 is fixedly installed inside both sides of the fixed frame 15, and the drive shafts at both ends of the dual-axis motor 16 are connected to the slag cleaning disc 17 via splines. The slag cleaning disc 17 consists of a mounting plate and a hard steel brush. The distance between the two ends of the slag cleaning disc 17 on opposite sides of the dual-axis motor 16 is the same as the distance between two adjacent sword grid plates 2. The dual-axis motor 16 drives the slag cleaning disc 17 at both ends to rotate at high speed, which can remove the slag adhering to the sides of the sword grid plate 2. The cleaning process is carried out by means of a first and second transverse drive mechanism. The cleaning discs 17 on the two fixed frames 15 are positioned close to each other and are positioned on opposite sides of the same sword grid plate 2. The second electric push rod 14 is used to press the cleaning discs 17 on the two fixed frames 15 close to each other onto the two sides of the sword grid plate 2. Since the distance between the cleaning discs 17 on opposite sides of the dual-axis motor 16 is the same as the distance between two adjacent sword grid plates 2, the cleaning discs 17 on opposite sides of the two fixed frames 15 can be pressed against the sides of the adjacent sword grid plates 2. This allows multiple cleaning discs 17 to clean the slag on the sides of multiple sword grid plates 2 simultaneously. When the cleaning discs 17 are rotating at high speed to clean the slag, the second transverse drive mechanism can drive the second movable frame 5 to move at a constant speed, thereby cleaning the entire side of the sword grid plate 2 along the direction of the sword grid plate 2, which greatly improves the cleaning efficiency.

[0028] The first electric push rod 7, the first drive motor 8, the second drive motor 11, the second electric push rod 14, and the dual-axis motor 16 are all electrically connected to the external control unit and are all electrically connected to the external circuit through wires.

[0029] In summary, the operating steps of this slag removal and splash prevention mechanism for laser cutting of alloy plates are as follows:

[0030] 1. In the initial state, multiple sword grid plates 2 are in a vertical state for use during laser cutting. After a period of laser cutting, the top of the sword grid plates 2 will be covered with molten slag produced during cutting. At this time, the movable rod of the first electric push rod 7 can be controlled to retract inward during the interval of changing the cutting plate. Through the rack frame 6, all the gear shafts 3 are driven to rotate 180 degrees counterclockwise, so that all the sword grid plates 2 can also rotate 180 degrees, so that the bottom of the sword grid plate 2 that was originally covered with molten slag rotates to the bottom, and the bottom rotates to the top.

[0031] 2. Then control the first drive motor 8 and the second drive motor 11 to run synchronously, and move the slag removal mechanism to below the sword grid plate 2 that needs to be slag removed;

[0032] 3. Next, control the movable rod of the second electric push rod 14 to rise, so that the slag cleaning disc 17 contacts the side of the sword grid plate 2, and run the dual-axis motor 16 to clean the slag adhering to the side of the sword grid plate 2.

[0033] 4. Next, the second drive motor 11 can be run again to make the second threaded screw 12 drive the second movable frame 5 to move slowly and uniformly along the direction of the limit rod 13, so that the high-speed rotating cleaning disc 17 can move along the side of the sword grid plate 2 and effectively clean all parts of the side of the sword grid plate 2.

[0034] 5. When it is necessary to clean the next sword grid plate 2, control the second electric push rod 14 to lower the movable rod body, so that the slag removal mechanism falls down, and adjust the position of the slag removal mechanism through the first transverse drive mechanism so that it corresponds to the next sword grid plate 2. Then repeat steps 3 and 4, and operate in this cycle. This can quickly and thoroughly clean the molten slag on the sword grid plate 2 without affecting the cutting operation.

[0035] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
