[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] For ease of understanding and description, the following description of this utility model uses absolute positional relationships. Unless otherwise specified, the directional term "upper" indicates perpendicular to. Figure 1 The direction of the paper is pointed outwards from the paper surface; the directional word "down" indicates perpendicular to the direction of the paper surface.

[0032] like Figures 1 to 2As shown in the embodiment of this utility model, a descaling and marking system for a continuous casting machine includes a marking robot 1, a lifting baffle 2, a descaling device 3, and a conveying roller conveyor 4. The conveying direction of the conveying roller conveyor 4 is from front to back. The descaling device 3 and the marking robot 1 are both located on the left or right side of the conveying roller conveyor 4 (i.e., the descaling device 3 and the marking robot 1 are both located on the same side of the conveying roller conveyor 4). The lifting baffle 2 is located behind the marking robot 1 and can prevent the billet 6 on the conveying roller conveyor 4 from moving backward. The descaling device 3 is located in front of the marking robot 1.

[0033] like Figure 1 As shown, the numbering robot 1 includes a base 11, a multi-axis robotic arm 12, and a pigment spraying device 13 connected in sequence. For example, if the billet 6 is a slab, the numbering robot 1 can spray numbers onto the left or right side of the billet 6 on the conveyor roller 4 accordingly.

[0034] For example, when both the descaling device 3 and the marking robot 1 are located on the left side of the conveyor roller 4, the marking robot 1 can spray a number onto the left side of the billet 6 on the conveyor roller 4; when both the descaling device 3 and the marking robot 1 are located on the right side of the conveyor roller 4, the marking robot 1 can spray a number onto the right side of the billet 6 on the conveyor roller 4.

[0035] The inkjet printing robot 1 can utilize existing technology. The base 11 is directly or indirectly fixed to the ground. The base 11 serves to mount a multi-axis robotic arm 12, which enables the inkjet printing device 13 to have six degrees of freedom. The inkjet printing device 13 includes an ink tank 131, an ink pump 132, and a nozzle 133 connected in sequence. The ink pump 132 causes the ink in the ink tank 131 to be ejected from the nozzle 133. Figure 3 As shown.

[0036] like Figures 1 to 2 As shown, the descaling and marking system of the continuous casting machine includes a protective railing 5, which is located around the base 11. The protective railing 5 contains a door 51, which can be opened or closed. The purpose of the door 51 is to prevent unauthorized personnel from approaching when the marking robot 1 is moving, so as to avoid mechanical injury.

[0037] Preferably, the guardrail 5 is higher than the base 11. The guardrail 5 can be rectangular in shape, and its height can be 1 meter to 2 meters. The door 51 is located on the side of the guardrail 5 facing away from the conveyor roller 4. For example, when the guardrail 5 is located on the left side of the conveyor roller 4, the door 51 is located on the left side of the guardrail 5; when the guardrail 5 is located on the right side of the conveyor roller 4, the door 51 is located on the right side of the guardrail 5.

[0038] The function of the descaling device 3 is to grind the surface of the billet 6 before spraying. The descaling device 3 contains a grinding wheel 31, a grinding wheel rotation drive mechanism 32 and a grinding wheel transverse movement drive mechanism 33 connected in sequence. The grinding wheel rotation drive mechanism 32 can drive the grinding wheel 31 to rotate, and the grinding wheel transverse movement drive mechanism 33 can make the grinding wheel 31 move left and right.

[0039] like Figure 1 and Figure 4 As shown, the grinding wheel transverse drive mechanism 33 includes a transverse base 331, a transverse rack 332, a drive gear 333, and a transverse drive motor 334 connected in sequence. The transverse base 331 and the transverse rack 332 are connected and fixed. The transverse rack 332 extends in the left and right direction. The transverse rack 332 and the drive gear 333 are meshed and connected. The drive gear 333 is coaxially connected and fixed with the output shaft of the transverse drive motor 334. The transverse drive motor 334 can drive the transverse base 331 to move left and right.

[0040] The grinding wheel rotation drive mechanism 32 includes a grinding wheel rotation motor 321. The output shaft of the grinding wheel rotation motor 321 extends in the left and right direction. The housing of the grinding wheel rotation motor 321 is vertically connected and fixed to the transverse base 331. The grinding wheel 31 is coaxially connected and fixed to the output shaft of the grinding wheel rotation motor 321. The axial end face of the grinding wheel 31 can grind the left or right side of the billet 6 on the conveyor roller 4 accordingly.

[0041] At this time, as Figure 1 and Figure 4 As shown, the axis of the grinding wheel 31 extends in the left-right direction. The grinding wheel rotary motor 321 can drive the grinding wheel 31 to rotate around the output shaft of the grinding wheel rotary motor 321. For example, when the descaling device 3 and the marking robot 1 are both located on the left side of the conveyor roller 4, the right end face of the grinding wheel 31 can grind the left side of the casting 6 on the conveyor roller 4; when the descaling device 3 and the marking robot 1 are both located on the right side of the conveyor roller 4, the left end face of the grinding wheel 31 can grind the right side of the casting 6 on the conveyor roller 4.

[0042] Or, such as Figure 5 As shown, the grinding wheel rotation drive mechanism 32 includes a grinding wheel rotation motor 321. The output shaft of the grinding wheel rotation motor 321 extends in the vertical direction. The housing of the grinding wheel rotation motor 321 is connected and fixed to the transverse base 331 vertically via a connecting arm 322. The grinding wheel 31 is coaxially connected and fixed to the output shaft of the grinding wheel rotation motor 321. The side circumferential surface of the grinding wheel 31 can correspondingly grind the left or right side of the billet 6 on the conveyor roller 4.

[0043] At this time, the axis of the grinding wheel 31 extends in the vertical direction, and the grinding wheel rotary motor 321 can drive the grinding wheel 31 to rotate around the output shaft of the grinding wheel rotary motor 321. For example, when the descaling device 3 and the spraying robot 1 are both located on the left side of the conveyor roller 4, the side circumferential surface of the grinding wheel 31 can grind the left side of the casting 6 on the conveyor roller 4; when the descaling device 3 and the spraying robot 1 are both located on the right side of the conveyor roller 4, the side circumferential surface of the grinding wheel 31 can grind the right side of the casting 6 on the conveyor roller 4.

[0044] like Figure 1 As shown, the conveyor roller 4 contains multiple conveyor rollers 41. The numbering robot 1 is located outside one end of the conveyor roller 41. The other end of the conveyor roller 41 is connected to the roller drive mechanism 42. The other end of the conveyor roller 41 is connected to the roller drive mechanism 42 in a one-to-one correspondence. The roller drive mechanism 42 can change the conveying speed of the conveyor roller 4.

[0045] The roller drive mechanism 42 enables the conveyor roller 4 to have functions such as slow speed, fast speed, and stop, and can realize the slow speed, fast speed and stop conveying of the billet 6 on the conveyor roller 4. It is used to cooperate with the descaling device 3 and the spraying robot 1 to realize descaling, spraying and other related functions.

[0046] The lifting baffle 2 is located between two adjacent conveyor rollers 41 behind the marking robot 1. The lifting baffle 2 is connected to a lifting mechanism, which can be a hydraulic mechanism. This mechanism allows the lifting baffle 2 to rise and fall. When the lifting baffle 2 is in the raised state, the billet 6 on the conveyor roller 4 can touch the lifting baffle 2 as it moves backward, and the lifting baffle 2 can prevent the billet 6 from moving further backward. When the lifting baffle 2 is in the lowered state, the billet 6 on the conveyor roller 4 cannot touch the lifting baffle 2 as it moves backward, and the lifting baffle 2 cannot prevent the billet 6 from moving further backward; that is, the billet 6 can move backward and pass over the lifting baffle 2.

[0047] The following describes the working process of the descaling and marking system of the continuous casting machine.

[0048] like Figure 1 As shown, the billet 6 (such as a slab) moves from front to back under the conveying roller 4. The conveying direction of the conveying roller 4 is direction A. When the billet head approaches the descaling device 3, the grinding wheel 31 of the descaling device 3 extends and starts to rotate. The conveying roller 4 decelerates so that the billet 6 slowly passes through the descaling device 3. At this time, the grinding wheel 31 of the descaling device 3 grinds and removes the iron oxide scale on the side of the billet 6. After removing the iron oxide scale, the grinding wheel 31 of the descaling device 3 stops rotating and retracts.

[0049] The conveyor rollers 4 continue to transport the billet 6 backward. As it approaches the marking stop position, the lifting baffle 2 rises under hydraulic pressure. With the lifting baffle 2 in the raised state, the billet 6 collides with the lifting baffle 2 and stops at the marking position, at which point the conveyor rollers 4 cease transport. The multi-axis robotic arm 12 moves (including shifting and rotating) the pigment spraying device 13 to the marking position. The pigment spraying device 13 sprays markings onto the descaled area on the side of the billet 6. After marking is completed, the multi-axis robotic arm 12 returns the pigment spraying device 13 to the standby position, marking is complete. The lifting baffle 2 descends under hydraulic pressure. With the lifting baffle 2 in the lowered state, the conveyor rollers 4 start to continue transporting the billet 6 backward, which is then conveyed to the next process.

[0050] The above description is merely a specific embodiment of this utility model and should not be construed as limiting the scope of its implementation. Therefore, any substitution of equivalent components or equivalent changes and modifications made within the scope of protection of this utility model should still fall within its coverage. Furthermore, the technical features, technical solutions, and embodiments of this utility model can be freely combined and used.
