Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figure 1-4 This utility model provides a high-efficiency casting roll slitting device, including a machine housing 1. Two symmetrically distributed through slots 11 are provided through the upper side wall of the machine housing 1. A gantry frame 2 is fixedly connected to the top wall of the machine housing 1. A cylinder 21 is installed on the upper outer wall of the gantry frame 2. The output shaft of the cylinder 21 passes through the upper side wall of the gantry frame 2 and is fixedly connected to a slitting frame 3. Two fixing rods 31 are fixedly connected between the inner walls of the two sides of the slitting frame 3. Multiple follower blocks 32 are slidably sleeved between the two fixing rods 31. A mounting plate 33 is fixedly connected to the front side wall. A cutting mechanism 34 is provided on the mounting plate 33. The output shaft of the cylinder 21 can push the slitting frame 3 to move down. During the downward movement, the cutting blade of the cutting mechanism 34 can complete the cutting of the casting roll. It can also complete the cutting of multiple equidistant small segments in one operation, which greatly shortens the cutting time and improves production efficiency. A variable pitch mechanism 4 is also provided on the slitting frame 3. A clamping mechanism 5 is provided inside the machine box 1. A top pressing mechanism 6 is also provided on the two mounting plates 33 on both sides.

[0024] Specifically, such as Figure 2As shown, a high-efficiency casting roll slitting device includes a pitch-changing mechanism 4 comprising a slotted plate 41, an electric push rod 42, pitch-changing grooves 43, and an actuating rod 44. The slotted plate 41 is slidably disposed between the inner walls of both sides of the slitting frame 3. An electric push rod 42 is mounted on the upper outer wall of the slitting frame 3. The output shaft of the electric push rod 42 passes through the upper side wall of the slitting frame 3 and is fixedly connected to the slotted plate 41. Multiple pitch-changing grooves 43 are provided through the slotted plate 41. An actuating rod 44 is slidably disposed within each pitch-changing groove 43. The front end of the actuating rod 44 is fixedly connected to a follower block 32. The position of the slotted plate 41 is controlled by extending or retracting the output shaft of the electric push rod 42. When the slotted plate 41 moves up and down, the actuating rod 44 moves the follower block 32 under the action of the pitch-changing grooves 43, thereby synchronously increasing or decreasing the distance between each cutting mechanism 34. This allows for adjustment of the distance between the cutting mechanisms 34 according to production needs, making it more flexible and practical.

[0025] Specifically, such as Figure 3 As shown, a high-efficiency casting roll slitting device includes a clamping mechanism 5 comprising a bidirectional screw 51, a handwheel 52, moving blocks 53, clamping plates 54, and limiting rods 55. The bidirectional screw 51 is rotatably mounted on one side inner wall of the housing 1. The other end of the bidirectional screw 51 passes through the other side wall of the housing 1 and is fixedly connected to the handwheel 52. Two symmetrically distributed moving blocks 53 are threaded onto the bidirectional screw 51. The upper side wall of the moving blocks 53 passes through the through groove 11 and is fixedly connected to the clamping plate 54. Two limiting rods 55 are fixedly connected to one side inner wall of the housing 1. The other end of the limiting rods 55 slides through the two moving blocks 53 and is fixedly connected to the other side inner wall of the housing 1. Rotating the handwheel 52 can drive the bidirectional screw 51 to rotate. When the bidirectional screw 51 rotates, the two moving blocks 53 can move closer to each other under the limitation of the limiting rods 55, thereby causing the two clamping plates 54 to move closer synchronously, clamping and fixing the casting roll.

[0026] Specifically, such as Figure 4 As shown, a high-efficiency casting roll slitting device includes a pressing mechanism 6 comprising a sleeve 61, a sliding plate 62, a pressure rod 63, a pressure block 64, and a clamping spring 65. The sleeve 61 is fixedly connected to two mounting plates 33 on both sides via brackets. The sliding plate 62 slides within the sleeve 61. A pressure rod 63 is fixedly connected to the lower side wall of the sliding plate 62. The lower end of the pressure rod 63 extends to the outside of the sleeve 61 and is fixedly connected to the pressure block 64. A clamping spring 65 is provided between the sliding plate 62 and the upper inner wall of the sleeve 61. During the downward movement of the slitting frame 3, the two pressure blocks 64 preferentially contact the casting roll. Under the obstruction of the casting roll, the pressure rod 63 pushes the sliding plate 62 upward, compressing the clamping spring 65. During the cutting process, under the push of the clamping spring 65, the pressure rod 63 continuously pushes the pressure block 64 downward, applying downward pressure to the casting roll, improving the fixing effect on the casting roll, and ensuring the stability of the casting roll during cutting.

[0027] Specifically, such as Figure 1 As shown, a high-efficiency casting roll slitting device is provided. Guide rods 22 are slidably inserted on the upper side wall of the gantry frame 2 and on both sides of the cylinder 21. The lower end of the guide rods 22 is fixedly connected to the slitting frame 3. When the output shaft of the cylinder 21 drives the slitting frame 3 to move up and down, the guide rods 22 can make the slitting frame 3 move more smoothly.

[0028] Specifically, such as Figure 1 As shown, a high-efficiency casting roll slitting device is provided with a placement seat at the center of the upper outer wall of the machine housing 1 for placing the casting roll to be slitting.

[0029] It should be noted that this utility model is a high-efficiency casting roll slitting device. In use, the casting roll is placed on the placement seat, and then the handwheel 52 is turned to drive the bidirectional screw 51 to rotate. When the bidirectional screw 51 rotates, the two moving blocks 53 move closer to each other under the limitation of the limiting rod 55, thereby causing the two clamping plates 54 to move closer synchronously, clamping and fixing the casting roll. Then, the cutting mechanism 34 and cylinder 21 are activated. The cutting mechanism 34 is mature existing technology and will not be described in detail here. The output shaft of the cylinder 21 pushes the slitting frame 3 downwards. During the downward movement of the slitting frame 3, the two pressure blocks 64 will preferentially contact the casting roll, and under the obstruction of the casting roll, the pressure rod 63 pushes the sliding plate 62 upwards, causing the clamping spring 6... During the compression and cutting process, under the push of the clamping spring 65, the pressure rod 63 continuously pushes the pressure block 64 downward, applying downward pressure to the casting roll, improving the fixing effect of the casting roll, and ensuring the stability of the casting roll during cutting. As the slitting frame 3 moves downward, the cutting blade of the cutting mechanism 34 completes the slitting of the casting roll. When it is necessary to change the slitting length, the position of the slot plate 41 is controlled by controlling the extension and retraction of the output shaft of the electric push rod 42. When the slot plate 41 moves up and down, under the action of the variable pitch slot 43, the action rod 44 will drive the follower block 32 to move, so that the distance between each cutting mechanism 34 increases or decreases synchronously. The distance between the cutting mechanisms 34 can be adjusted according to production needs, making it more flexible and practical.
