Its technical scheme is as follows: it comprises a high-pressure nitrogen purge part and a mechanical cleaning part, the upper end of the high-pressure purge pipe is connected to the high-pressure nitrogen pipeline, the lower end of the high-pressure purge pipe is connected to the blowing nozzle, and the blowing nozzle is located below the continuous casting billet; the pressing arm is located below the billet discharge roller of the fixed-length continuous casting billet after cutting, the front end of the pressing arm is equipped with a pressing guide wheel, the pressing arm is connected to the swing cutting arm through an adjusting screw, the middle part of the swing cutting arm is provided with a lever shaft, the rear end of the swing cutting arm is equipped with a cutting knife, and the cutting knife is opposite to the lower surface of the fixed-length continuous casting billet; the utility model can remove the front end nodules and the rear end nodules of the continuous casting billet respectively, and quickly and effectively clean the nodules on the two cutting end faces of the continuous casting billet while the continuous casting billet is being cut, with high efficiency, clean and thorough cutting, and a cleaning degree of 100%;

[0027] In this embodiment, the mounting frame 4 is located below the gap between the two conveying rollers 2 in the middle section of the frame 1, and the conveying rollers 2 will not block the mounting frame 4 from moving up and down. The infrared sensor 12 is composed of an infrared transmitter and an infrared receiver. When the continuous casting billet moves to the position of the infrared sensor 12, it will block the signal emitted by the infrared transmitter, thereby preventing the infrared receiver from receiving the signal and triggering the controller 11 to start the cutting tumor cleaning program. The first cylinder 3, the first motor 10 and the infrared sensor 12 are all electrically connected to the controller 11. The electrical connection between the first cylinder 3 and the controller 11 is achieved by connecting one end of the cable to the coil or interface of the first cylinder 3 and the other end to the corresponding end of the controller 11. The controller 11 controls the action of the first cylinder 3 by sending an electrical signal. During operation, when the continuous casting billet is conveyed to the position of the infrared sensor 12 on the conveying roller 2, the controller 11 controls the first cylinder 3 to start, so that it drives the first grinding wheel 5, the second grinding wheel 6 and the third grinding wheel 7 to move upward, and at the same time turns on the first motor 10 to drive the first grinding wheel 5, the second grinding wheel 6 and the third grinding wheel 7 to rotate, thereby grinding and cleaning the cutting nodules on the continuous casting billet. The first synchronous belt 8 and the second synchronous belt 9 are designed to allow the first grinding wheel 5, the second grinding wheel 6 and the third grinding wheel 7 to rotate synchronously, so that the first motor 10 can simultaneously drive the first grinding wheel 5, the second grinding wheel 6 and the third grinding wheel 7 to rotate.

[0028] Further, such as Figure 2 As shown, the first grinding wheel 5 is located at one end of the first synchronous belt 8 and is fixedly connected to the first synchronous wheel 13, the second grinding wheel 6 is located at one end of the first synchronous belt 8 and is fixedly connected to the second synchronous wheel 14, the first synchronous wheel 13 and the second synchronous wheel 14 are both meshed and connected with the first synchronous belt 8, the second grinding wheel 6 is located at one end of the second synchronous belt 9 and is fixedly connected to the third synchronous wheel 15, the third grinding wheel 7 is located at one end of the second synchronous belt 9 and is fixedly connected to the fourth synchronous wheel 16, and the third synchronous wheel 15 and the fourth synchronous wheel 16 are both meshed and connected with the second synchronous belt 9;

[0031] In this embodiment, the first U-shaped plate 19 is driven downward by the second cylinder 18, thereby driving the pressure roller 20 to move downward, thereby pressing the continuous casting billet so that the continuous casting billet will not shake up and down when the cutting nodules are cleaned.

[0032] Further, such as Figure 3 As shown, the side walls at both ends of the first support frame 17 are respectively provided with first slide grooves 21, and the first U-shaped plate 19 is respectively fixedly connected with first sliders 22 at both ends, and the first slide grooves 21 are slidably connected with the first sliders 22;

[0033] In this embodiment, the design of the first sliding groove 21 and the first sliding block 22 makes the first U-shaped plate 19 more stable when moving up and down.

[0034] Further, such as Figure 4 and Figure 5 As shown, the frame 1 is located on both sides of the first support frame 17 and is fixedly connected to the second support frame 23, one end of the top of the second support frame 23 is fixedly connected to the second motor 24, the output end of the second motor 24 is fixedly connected to a bidirectional threaded rod 25, both ends of the bidirectional threaded rod 25 are respectively threadedly connected to collars 26, the bottom of the collar 26 is fixedly connected to a connecting rod 27, the connecting rod 27 is slidably connected to the second support frame 23, the bottom of the connecting rod 27 is fixedly connected to a second U-shaped plate 28, and one end of the second U-shaped plate 28 is rotatably connected to a clamping roller 29;

[0035] In this embodiment, the bidirectional threaded rod 25 is driven to rotate by the second motor 24, thereby driving the two clamping rollers 29 to move synchronously in opposite directions, thereby clamping both ends of the first continuous casting billet, so that the continuous casting billet will not shake left and right when the nodules are cleaned and cut.

[0036] Further, such as Figure 4 As shown, the second support frame 23 is provided with a through slot 30 below the bidirectional threaded rod 25, and the through slot 30 is slidably connected to the connecting rod 27;

[0037] In this embodiment, the design of the through slot 30 allows the bottom of the connecting rod 27 to smoothly pass through the second support frame 23, and allows the clamping rollers 29 to be located at both ends of the continuous casting billet.

[0038] Further, such as Figure 4 and Figure 5 As shown, a sliding rod 31 is fixedly connected to one end of the side wall of the second U-shaped plate 28, and the sliding rod 31 is slidably connected to the second support frame 23. Second sliding grooves 32 are respectively provided at both ends of the bottom of the second support frame 23. A second sliding block 33 is fixedly connected to the bottom of the second U-shaped plate 28, and the second sliding groove 32 is slidably connected to the second sliding block 33;

[0039] In this embodiment, the design of the slide bar 31 , the second slide groove 32 and the second slide block 33 makes the second U-shaped plate 28 more stable when moving.

[0040] Further, such as Figure 1 and Figure 6 As shown, the frame 1 is located at one end of the conveying roller 2 and is fixedly connected to a third motor 34, the output end of the third motor 34 is fixedly connected to the conveying roller 2, the frame 1 is located below the first cylinder 3 and is fixedly connected to a support frame 35, and the support frame 35 is fixedly connected to the first cylinder 3;

[0041] In this embodiment, the third motor 34 is designed to drive the conveying roller 2 to rotate, and the support frame 35 is designed to allow the first cylinder 3 to be smoothly fixedly connected to the frame 1.

[0042] Working principle: When the continuous casting billet moves to one end of the frame 1, the infrared sensor will sense the position of the continuous casting billet and transmit the signal to the controller 11. At this time, the controller 11 controls the first air pump to start, so that it drives the first grinding wheel 5, the second grinding wheel 6 and the third grinding wheel 7 to move upward, and at the same time, the first motor 10 is turned on to drive the first grinding wheel 5, the second grinding wheel 6 and the third grinding wheel 7 to rotate, so as to grind and clean the cutting nodules on the continuous casting billet. In this process, it is necessary to turn on the second cylinder 18 at the same time, so that the second cylinder 18 drives the pressure roller 20 to move downward and press the continuous casting billet, so that the continuous casting billet will not shake up and down when the cutting nodules are cleaned. At the same time as the second cylinder 18 is turned on, the second motor 24 is turned on to drive the bidirectional threaded rod 2 5 is rotated, and the two sleeve rings 26 will move in the opposite direction synchronously under the drive of the bidirectional threaded rod 25, thereby driving the two connecting rods 27 to move in the opposite direction synchronously, and then driving the two pressure rollers 20 to move in the opposite direction synchronously, so as to clamp the two ends of the continuous casting billet, so that the continuous casting billet will not shake left and right when the cutting nodules are cleaned. In addition, by rotating and connecting the pressure roller 20 and the first U-shaped plate 19 together, and rotating and connecting the clamping roller 29 and the second U-shaped plate 28 together, the continuous casting billet can still move forward in the process of cleaning the cutting nodules, and will not affect the billet discharge efficiency. Through the joint action of the pressure roller 20 and the clamping roller 29, the continuous casting billet will not shake when the cutting nodules are cleaned, thereby ensuring the cleaning effect of the cutting nodules.
