Description

Technical Field

[0001] This utility model relates to the field of casting and rolling mill technology, and in particular to a self-cleaning device for casting and rolling mill roll surfaces. Background Technology

[0002] A casting and rolling mill is a piece of equipment used to produce sheet metal, primarily for directly casting molten metal into sheets of a certain thickness and width. This equipment is widely used in the metal processing industry, especially in the production of non-ferrous metals such as aluminum and zinc.

[0003] Patent application CN217964098U discloses a roll changing device for a casting and rolling mill, comprising a U-shaped mounting base and two casting and rolling rolls spaced vertically apart. The casting and rolling rolls are horizontally positioned. Two rotating shafts, coaxial with the corresponding casting and rolling rolls, are rotatably connected to the inner walls of opposite sides of the mounting base. Each of the two opposite rotating shafts has a fixed semi-ring for the lower part of the casting and rolling roll end to be embedded in. The upper end of the fixed semi-ring is slidably connected along the axial direction of the rotating shaft to a movable semi-ring for the upper part of the casting and rolling roll end to be embedded in. The fixed and movable semi-rings jointly clamp the end of the casting and rolling roll. The movable semi-ring is locked to the rotating shaft by a locking device. The inner wall of the fixed semi-ring has a limiting post that slides radially through the casting and rolling roll, and the inner wall of the movable semi-ring has a limiting plate that slides axially through the casting and rolling roll. This application facilitates the assembly and disassembly of the casting and rolling rolls.

[0004] The pressure roll is a core working component of the casting and rolling mill, and its surface cleanliness is crucial to the final product quality. Since this casting and rolling mill lacks a cleaning device, impurities or metal shavings adhering to the roll surface can damage the strip or sheet material, resulting in indentations or even breakage, severely impacting the final product quality. To address these issues, we have introduced a self-cleaning device for the casting and rolling mill roll surface. Utility Model Content

[0009] In a preferred embodiment, a fixing frame is fixedly connected to the bottom of the mounting frame, and a first motor is disposed inside the fixing frame. One end of the output shaft of the first motor and one end of the reciprocating lead screw are both fixedly connected to a synchronous pulley. A synchronous belt is disposed on the outer side of the synchronous pulley, and a drain outlet is fixedly connected to the bottom of one of the mounting frames.

[0010] In a preferred embodiment, the displacement assembly includes a fixing block, which is fixedly connected to both sides of the mounting frame.

The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0022] The self-cleaning device for casting and rolling mill roll surfaces disclosed in this utility model is mainly applied to casting and rolling mill scenarios.

[0023] Reference Figures 1 to 6 The self-cleaning device for the roller surface of a casting and rolling mill includes: a base 1, a mounting frame 2 fixedly connected to the top of the base 1, a bearing 3 inside the mounting frame 2, a mounting rod 4 rotatably connected inside the bearing 3, two casting and rolling rollers 5 inside the mounting frame 2, a connecting block 6 fixedly connected to one end of each of the two casting and rolling rollers 5, a bolt 7 between the connecting block 6 and the mounting rod 4, two mounting frames 8 inside the mounting frame 2, a cleaning component inside each of the two mounting frames 8, and a displacement component on one side of the mounting frame 2. The cleaning assembly includes a reciprocating screw 9, which is rotatably connected inside the mounting frame 8. A first mounting block 10 is threadedly connected to the outside of the reciprocating screw 9. Two connecting rods 11 are slidably connected inside the first mounting block 10. A polishing stone 12 is fixedly connected to the top of the two connecting rods 11. The top of the polishing stone 12 abuts against the bottom of the casting roller 5. A spring 13 is provided on the outside of the connecting rods 11. The mounting frame 8 has two fixedly connected sliding rods 14 inside, and the outer sides of the two sliding rods 14 are slidably connected to second mounting blocks 15. The top of the second mounting blocks 15 is fixedly connected to a nozzle 16. A fixing rod 17 is fixedly connected to one side of both the first mounting block 10 and the second mounting block 15. A mounting strip 18 is slidably connected to the outside of the fixing rod 17, and a nut 19 is threadedly connected to the outside of the fixing rod 17. A fixed frame 20 is fixedly connected to the bottom of the mounting frame 8. A first motor 21 is installed inside the fixed frame 20. One end of the output shaft of the first motor 21 and one end of the reciprocating lead screw 9 are both fixedly connected to a synchronous pulley 22. A synchronous belt 23 is installed on the outside of the synchronous pulley 22. A drain outlet 24 is fixedly connected to the bottom of one of the mounting frames 8.

[0024] In the above technical solution, considering that the pressure roll is the core working component of the casting and rolling mill, its surface cleanliness is crucial to the production quality of the final product. Since the casting and rolling mill is not equipped with a cleaning device, if impurities or metal fragments adhere to the surface of the roll, it will cause damage to the surface of the strip or plate. This can lead to indentations or even damage on the surface of the strip or sheet material, seriously affecting the final quality of the product. To solve this problem, the specific operation is as follows: By setting up a cleaning component, when it is necessary to clean the surface of the casting roll 5, connect the external water pipe to one end of the nozzle 16, place a water bucket at the bottom of the inner wall of the mounting frame 2, and spray the water delivered through the nozzle 16 onto the surface of the casting roll 5 for rinsing. Start the external motor to drive the casting roll 5 to rotate at a uniform speed, and at the same time start the first motor 21. Use the synchronous pulley 22 and the synchronous belt 23 to drive the reciprocating screw 9 to rotate. Use the mounting strip 18 to connect the first mounting block 10 and the second mounting block 15 and restrict them to each other, so that the first mounting block 10 moves back and forth on the surface of the reciprocating screw 9, and the second mounting block 15 moves back and forth on the surface of the slide bar 14. The polishing stone 12 on the top of the first mounting block 10 is always attached to the casting roll 5 under the elasticity of the spring 13 to polish its surface. Finally, all the wastewater flows into the mounting frame 8 below and flows into the water bucket from the drain outlet 24. By setting up cleaning components, a dual cleaning mechanism is formed by combining the physical polishing of the polishing stone 12 and the water rinsing of the nozzle 16. The polishing stone 12 can remove stubborn impurities and metal debris from the surface of the casting roll 5, while the water flow can wash away the debris generated during the polishing process, ensuring that the surface of the casting roll 5 is thoroughly cleaned. The back-and-forth movement of the polishing stone 12 and the nozzle 16 ensures that every part of the surface of the casting roll 5 is cleaned evenly.

[0025] Reference Figures 1 to 6 In a preferred embodiment, the displacement assembly includes fixed blocks 25, which are fixedly connected to both sides of the mounting frame 2. A bidirectional lead screw 26 and a limiting rod 27 are respectively provided on the top of each fixed block 25. A second motor 28 is provided on one side of the mounting frame 2, and the bottom of the output shaft of the second motor 28 is fixedly connected to the top of the bidirectional lead screw 26. Movable slots 29 are equidistantly provided inside the mounting frame 2. Crossbars 30 are provided on both sides of the mounting frame 8, and a movable block 31 is fixedly connected to one end of each crossbar 30. The interior of one movable block 31 is threadedly connected to the outer side of the bidirectional lead screw 26. Another movable block 31 is slidably connected to the outside of the limiting rod 27. When the surface of the casting roller 5 needs to be cleaned, the second motor 28 can be started to drive the bidirectional lead screw 26 to rotate. The limiting rod 27 restricts the movement of the two sets of mounting frames 8 up and down, respectively approaching the corresponding casting roller 5. The cleaning component is used for cleaning. After the cleaning is completed, the second motor 28 is controlled to rotate in the opposite direction, causing the cleaning component to separate from the casting roller 5. In this way, when using the casting roller 5, the cleaning component can be prevented from affecting the casting roller 5, thus protecting both the component and the casting roller 5.

[0026] Working principle: When cleaning the surface of the casting roll 5 is required, the second motor 28 can be started to drive the bidirectional lead screw 26 to rotate. Using the limiting rod 27, the two sets of mounting frames 8 move up and down, respectively approaching the corresponding casting roll 5. An external water pipe is connected to one end of the nozzle 16. A water bucket is placed at the bottom of the inner wall of the mounting frame 2, and water is sprayed onto the surface of the casting roll 5 through the nozzle 16 for rinsing. The external motor is started to drive the casting roll 5 to rotate at a uniform speed. Simultaneously, the first motor 21 is started, using the synchronous pulley 22 and synchronous belt 23 to drive the reciprocating lead screw 9 to rotate. The mounting strip 18 is used to... Mounting block 10 and second mounting block 15 are connected and mutually restrict each other, so that first mounting block 10 moves back and forth on the surface of reciprocating screw 9, and second mounting block 15 moves back and forth on the surface of slide bar 14. The polishing stone 12 on the top of first mounting block 10 is always attached to the casting roller 5 under the elasticity of spring 13 to polish its surface. After finishing, the second motor 28 is controlled to rotate in the opposite direction, driving the cleaning component to separate from the casting roller 5. Finally, all wastewater flows into the mounting frame 8 below and flows into the water bucket from the drain outlet 24. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0027] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
