[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through its adjustable mechanism, allows the equipment to be flexibly adjusted to accommodate steel strips of different thicknesses. When it is necessary to adapt to steel strips of different thicknesses, the rotating block can be rotated, which drives the upper and lower screws to rotate. Since the screws are threadedly connected to the movable block, under the limiting action of the guide block and guide rod, the upper and lower movable blocks will move along the axial direction of the screws. The movement of the movable blocks drives the sliding rod to move, which in turn drives the disassembly and assembly mechanism and the sponge to move, thereby adjusting the distance between the sponge and the steel strip. This allows the sponge to fit tightly against the surface of the steel strip, effectively cleaning impurities on the surface of the steel strip. This avoids the problem of poor cleaning effect due to different steel strip thicknesses, and improves the comprehensiveness and effectiveness of cleaning.

[0014] 2. This utility model, through its designed disassembly and assembly mechanism, allows for convenient and quick replacement of the sponge. After a period of use, the cleaning effect of the sponge decreases, necessitating replacement. Simply pull the lever, which pulls the insert rod out of the slot of the placement block. At this time, the return spring is stretched, and the placement block is then removed from the placement groove, allowing the old sponge to be taken off. Next, the placement block corresponding to the new sponge is placed into the placement groove. Releasing the lever causes the return spring to pull the insert rod into the slot of the placement block, thus securing the sponge. The entire replacement process is simple and convenient, requiring no complicated operations, greatly saving replacement time and improving the efficiency of the equipment.

[0020] Preferably, the two openings 3 are respectively connected to the front and rear ends of the box body 1 to ensure unobstructed passage of the steel belt and efficient cleaning process.

[0021] Please see Figure 2 To quickly move the upper and lower pressure rods 69 inside the box 1 closer together or further apart, the adjustment mechanism 5 includes extension blocks 51. The inner ends of the two extension blocks 51 are fixedly connected to the middle of the left and right sides of the box 1, respectively. The outer end faces of the two extension blocks 51 are each provided with a rotating groove 52. Each rotating groove 52 is provided with a rotating block 53. The upper and lower ends of the rotating block 53 are fixedly connected with screws 54. The threads of the two screws 54 are opposite in direction.

[0023] Please see Figure 3 To quickly fix the pressure rod 69 onto the mounting block 61, the disassembly and assembly mechanism 6 includes the mounting block 61. The outer end face of the mounting block 61 is fixedly connected to the inner end face of the slide rod 510 to ensure structural stability and reliability. The inner end face of the mounting block 61 is provided with a placement groove 62 for accommodating and positioning the placement block 67. Movable grooves 63 are provided on one side of the front and rear ends of the mounting block 61. A return spring 64 is fixedly connected to one end of the inner wall of the movable groove 63, and a pull rod 65 is fixedly connected to the other end of the return spring 64. The elastic restoring force of the return spring 64 enables the pull rod 65 to automatically reset. One side of the pull rod 65... A rod 66 is fixedly connected to the outside of the movable slot 63, and the rod 66 can move synchronously with the movement of the pull rod 65. The inner wall of the placement slot 62 is tightly attached to the placement block 67 to ensure the accurate positioning of the placement block 67 in the slot. Slots 68 are opened in the middle of the front and rear ends of the placement block 67. The slots 68 and the rod 66 are interlocked and cooperated with each other. The fixing or release of the pressure rod 69 is achieved by inserting or withdrawing the rod 66 into or out of the slot 68. The pressure rod 69 is fixedly connected between the two adjacent ends of the left and right placement blocks 67 so that the pressure rod 69 can move together with the placement block 67.

[0024] Preferably, the end of the pull rod 65 away from the return spring 64 extends to the outside of the movable groove 63, which facilitates the movement of the pull rod 65; the top of the placement groove 62 extends to the top outside of the mounting block 61, which facilitates the replacement of the placement block 67; the outer end face of the mounting block 61 slides tightly against the inner wall of the mounting cavity 2, ensuring the correct positioning and reliable support of the entire disassembly and assembly mechanism 6 in the mounting cavity 2, thereby ensuring the stability and efficiency of the pressure rod 69 during operation.

[0025] Working principle: First, by installing the entire cleaning device between two sets of centering rollers, it is ensured that the steel strip can pass smoothly through the openings 3 at the front and rear ends of the box 1. When the uncoiled steel strip enters the device, the adjusting mechanism 5 is operated according to the thickness of the steel strip. Rotating the rotating block 53 causes the upper and lower screws 54 to rotate as the rotating block 53 is fixedly connected to the screw 54. The movable block 56 is threadedly connected to the screw 54. Under the guidance of the guide block 57 and the guide rod 58, the movable block 56 moves up and down along the screw 54, thereby driving the slide rod 510 to slide in the slide groove 4. The slide rod 510 is fixedly connected to the mounting block 61 in the disassembly and assembly mechanism 6, thereby causing the mounting block 61 to move up and down. Finally, the upper and lower pressure rods 69 move closer or further apart to adapt to steel strips of different thicknesses. When the pressure rod 69 needs to be installed or replaced, pull the pull rod 65 outward, the return spring 64 is stretched, and the pull rod 65 drives the insertion rod 66 out of the slot 68 on the placement block 67. At this time, the end of the placement block 67 can be removed from the placement groove 62, and then the pressure rod 69 can be removed. When installing a new pressure rod 69, put the end of the placement block 67 into the placement groove 62, release the pull rod 65, and under the elastic restoring force of the return spring 64, the pull rod 65 returns to its original position, and the insertion rod 66 is inserted into the slot 68, thereby fixing the pressure rod 69 on the mounting block 61. During the process of the steel strip passing through the device, the sponge 7 at the top and bottom of the mounting cavity 2 contacts the upper and lower surfaces of the steel strip, cleaning various impurities adhering to the surface of the steel strip and preventing impurities from entering the rolling and causing damage to the material surface or even the roller surface, affecting the molding quality and mold life; then, with the setting of two pressure rods 69, it can be flexibly adjusted according to the actual thickness of the steel strip to ensure that the pressure rods 69 and the edge of the steel strip maintain an appropriate distance, so that the cleaning effect is not reduced due to the distance being too far, and unnecessary pressure or damage to the steel strip is not caused by the distance being too close; Once the pressure bar 69 is adjusted to the appropriate position, the upper and lower surfaces of the steel strip will come into full contact with the two sponge bodies 7 in the mounting cavity 2 during continuous movement. These sponge bodies 7 are made of high-quality materials and have good dirt absorption capacity and elasticity. They can effectively absorb and scrape off various impurities such as rust, dust, and oil adhering to the surface of the steel strip. During the cleaning process, a relatively gentle friction is formed between the sponge body 7 and the surface of the steel strip. This friction can ensure that impurities are removed from the surface of the steel strip without causing scratches or wear to the surface of the steel strip, thereby ensuring the smoothness and flatness of the steel strip surface. Moreover, since the sponge body 7 is in full contact with the surface of the steel strip, it can clean the entire width range of the steel strip evenly without any cleaning dead corners, which greatly improves the comprehensiveness and effectiveness of cleaning. After a period of use, the surface of the sponge 7 will accumulate a lot of impurities, resulting in a decrease in cleaning effect. At this time, the sponge 7 can be quickly replaced using the disassembly and assembly mechanism 6. The operator only needs to pull the pull rod 65 to make the insertion rod 66 disengage from the slot 68 on the placement block 67, and take the placement block 67 together with the pressure rod 69 out of the placement groove 62. Then, the old sponge 7 can be easily removed from the installation cavity 2, replaced with a new sponge 7, and the placement block 67 is put back into the placement groove 62. The pull rod 65 is released, and under the action of the return spring 64, the insertion rod 66 is reinserted into the slot 68, and the pressure rod 69 is fixed. The whole replacement process is simple and quick, which can minimize the downtime of the equipment and improve production efficiency. Through the synergistic effect of this adjustment mechanism 5 and the disassembly and assembly mechanism 6, it can effectively prevent impurities adhering to the steel strip after uncoiling from entering the rolling and causing damage to the material surface or even the roller surface. The above is the working process of the whole device, and the contents not described in detail in this specification are all prior art known to those skilled in the art.
