Description
Technical Field
[0001] This application relates to the technical field of degreasing equipment for steel strip production, and in particular to a steel strip degreasing device. Background Technology
[0002] In the steel strip manufacturing industry, steel strip, as a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of different industrial sectors, is widely used in multiple industries. During the rolling process, rolling oil needs to be added to the working area to ensure smooth rolling operations, serving both cooling and lubrication purposes. When coiling the steel strip during production, any residual rolling oil on the surface must be thoroughly cleaned to prevent wrinkles from forming during coiling. Furthermore, the presence of oil can cause slippage between layers during coiling, making it difficult to coil evenly and affecting the transport and quality of the steel strip.
[0003] Existing steel belt degreasing equipment will accumulate dirt on the cleaning felt during long-term operation, affecting the degreasing effect. The entire degreasing equipment needs to be stopped before the cleaning felt can be replaced, which affects the efficiency of degreasing the steel belt. Utility Model Content
[0004] The purpose of this application is to provide a steel belt degreasing device that allows for the replacement of dirty cleaning felts during operation without stopping the equipment, while simultaneously performing degreasing and cleaning of the steel belt. This improves the efficiency of steel belt degreasing and solves the problem that existing steel belt degreasing equipment suffers from dirty cleaning felts during long-term operation, affecting the degreasing effect, and requires the entire degreasing equipment to be stopped before the cleaning felts can be replaced, thus impacting the efficiency of steel belt degreasing.
[0005] This application provides a steel strip degreasing device with the following technical solution: A steel strip degreasing device includes a base, two vertically distributed degreasing rollers on the top of the base, four limiting rollers on the right side of the degreasing rollers, the four limiting rollers being arranged in pairs, and two sets of cleaning components on the right side of the limiting rollers. Each cleaning component includes an upper adjusting block and a lower adjusting block, with mounting plates fixedly installed on opposite sides of the upper and lower adjusting blocks. Insert plates are inserted into the inner walls of one side of each of the two mounting plates, and cleaning felt is fixedly installed on opposite sides of each of the two insert plates. A first threaded rod is fixedly installed on the top of the upper adjusting block. The outer surface of the middle part of the first threaded rod is threadedly connected to the inner wall of the middle part of the threaded sleeve. The outer surface of the middle part of the threaded sleeve is rotatably installed in the inner wall of the middle part of the support frame. Two hydraulic rods are fixedly installed at both ends of the top of the upper adjusting block. The output ends of the two hydraulic rods pass through both ends of the adjusting block and are fixedly installed at both ends of the top of the lower adjusting block. A connecting frame is provided on the right side of the cleaning component. The connecting frame is fixedly installed on the top of the base. Two thickness detection sensors are fixedly installed on the bottom and top walls inside the connecting frame.
[0006] By adopting the above technical solution, the two oil removal rollers distributed vertically can remove large pieces of rolling oil or other oily impurities adhering to the steel strip. The pre-treated steel strip is limited by two sets of limiting rollers and enters between two cleaning felts for oil removal and cleaning. The position of the two cleaning felts can be adjusted by the rotation of the threaded sleeve and the threaded connection of the first threaded rod, switching the working state of the two sets of cleaning felts. The two sets of cleaning felts work alternately. By pulling the insert plate out from the mounting plate, the dirty cleaning felts can be easily disassembled without stopping the entire oil removal equipment, effectively avoiding the impact on the oil removal efficiency of the steel strip due to the replacement of cleaning felts. At the same time, the thickness detection sensor can monitor the thickness of the steel strip in real time to ensure the stability of the oil removal and cleaning process.

[0008] By adopting the above technical solution, the rotation of the worm gear driven by the operating handle can enable the worm wheel to precisely control the rotation of the threaded sleeve, and then the positions of the upper and lower adjusting blocks can be adjusted through the first threaded rod.
[0009] Preferably, a first limiting rod is fixedly provided on the top of the upper adjusting block, and the outer surface of the middle part of the first limiting rod is slidably connected to the inner wall of the middle part of the support frame.

[0011] Preferably, a fixing plate is fixedly provided at one end of the insert plate, and the fixing plate is fixedly installed at the end of the mounting plate by fastening bolts.
[0012] By adopting the above technical solution, the cooperation between the fixing plate and the fastening bolts allows the insert plate to be firmly installed on the mounting plate, ensuring the stability of the cleaning felt during operation. At the same time, when the cleaning felt needs to be replaced due to dirt, the insert plate can be removed simply by unfastening the fastening bolts, realizing the quick replacement of the cleaning felt and significantly improving work efficiency.
[0013] Preferably, the end of the degreasing roller is rotatably mounted inside the inner wall of one end of the swing rod via a rotating shaft, and the inner wall of the other end of the swing rod is hinged to the top of the base via a hinge frame. The swing rods corresponding to the upper and lower degreasing rollers are arranged symmetrically.
[0014] By adopting the above technical solution, the hinged structure of the swing rod allows the oil removal roller to flexibly adjust its angle and position according to the thickness of the steel strip, ensuring close contact between the oil removal roller and the surface of the steel strip, thus improving the oil removal effect. At the same time, this structure will not interfere with the replacement of the cleaning felt, ensuring the continuity of the overall operation of the equipment.
[0015] Preferably, an electric push rod is fixedly mounted on the top of the base via a support plate, and a push plate is fixedly mounted on the output end of the electric push rod. Two slide rods are fixedly mounted on both ends of the top of the push plate via support plates, and the outer surface of the middle part of the slide rod is slidably mounted in the inner wall of the slide groove opened in the middle of the swing rod.
[0016] By adopting the above technical solution, the electric push rod pushes the push plate, which can drive the slide bar to slide in the groove in the middle of the corresponding swing rod, thereby driving the swing rod to swing, which can conveniently adjust the distance between the two degreasing rollers.
[0017] Preferably, the bottoms of the two sets of limiting rollers are rotatably mounted on the top of the two connecting plates via a rotating shaft. The inner walls of the middle portion of the two connecting plates are threadedly connected to the outer surfaces of the middle two sides of the second threaded rod. The outer surfaces of both ends of the second threaded rod are rotatably mounted on the top of the base via two support plates. One end of the second threaded rod is provided with an operating handle. The thread directions of the outer surfaces of the middle two sides of the second threaded rod are opposite, and the thread directions of the outer surfaces of the middle two sides of the second threaded rod are adapted to the thread directions of the inner walls of the middle portion of the two connecting plates.
[0018] By adopting the above technical solution, rotating the second threaded rod can drive the two connecting plates to move relative to or in opposite directions, thereby adjusting the distance between the two sets of limit rollers to adapt to steel strips of different widths, ensuring that the steel strip does not shift during the degreasing process, and improving the stability of degreasing and cleaning.
[0019] Preferably, the inner walls of both ends of the connecting plate are slidably disposed on the outer surface of one side of the middle of the two second limiting rods, and the two ends of the second limiting rods are fixedly disposed on the top of the base by two support plates.
[0020] By adopting the above technical solution, the second limiting rod can limit the movement direction of the connecting plate, prevent the connecting plate from rotating or shifting during the adjustment process, and ensure that the limiting roller always maintains the correct position.
[0021] In summary, this application includes at least one of the following beneficial technical effects: This steel belt degreasing device uses two sets of cleaning components working alternately to adjust their operating states. The cleaning felt of the clean set cleans the steel belt, while the dirty set stops cleaning. The dirty cleaning felt can be easily replaced during operation without stopping the equipment. At the same time, the steel belt can still be degreased and cleaned normally during the replacement process, thus improving the efficiency of steel belt degreasing.
[0022] This steel belt degreasing device, when the degreasing roller wears down after long-term operation and the center line of the steel belt conveyor changes, can raise the height of the lower adjusting block by operating a hydraulic rod, thereby raising the height of the cleaning felt on the lower adjusting block. When the threaded sleeve rotates, the height of the upper and lower adjusting blocks can be adjusted by the first threaded rod, thus adjusting the working center line of the two cleaning felts, so that the working center line of the two cleaning felts can be adjusted according to the wear of the degreasing roller.

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.
[0026] Example 1: A steel strip degreasing device, please refer to [link / reference]. Figure 1 , Figure 2 and Figure 5 The system includes a base 1, with two vertically distributed degreasing rollers 2 on the top of the base 1. Four limiting rollers 3 are located to the right of the degreasing rollers 2, arranged in pairs. Two sets of cleaning components 4 are located to the right of the limiting rollers 3. Each cleaning component 4 includes an upper adjusting block 401 and a lower adjusting block 402. Mounting plates 403 are fixedly installed on opposite sides of both the upper and lower adjusting blocks 401 and 402. Insert plates 404 are inserted into the inner walls of one side of each mounting plate 403. Cleaning felt 405 is fixedly installed on opposite sides of each insert plate 404. A first cleaning felt 405 is fixedly installed on the top of the upper adjusting block 401. A threaded rod 6 is provided, with its outer surface threaded to the inner wall of the threaded sleeve 7. The outer surface of the threaded sleeve 7 is rotatably mounted on the inner wall of the support frame 11. Two hydraulic rods 21 are fixedly mounted at both ends of the top of the upper adjusting block 401. The output ends of the two hydraulic rods 21 pass through both ends of the upper adjusting block 401 and are fixedly mounted at both ends of the top of the lower adjusting block 402. A connecting frame 19 is provided on the right side of the cleaning component 4. The connecting frame 19 is fixedly mounted on the top of the base 1. Two thickness detection sensors 20 are fixedly mounted on the bottom and top walls inside the connecting frame 19.
[0027] Please see Figure 1 , Figure 2 and Figure 3 A worm gear 8 is fixedly installed at one end of the threaded sleeve 7. The worm gear 8 meshes with the worm 9. The outer surfaces of both ends of the worm 9 are rotatably mounted on the top of the support frame 11 via the support plate. An operating handle is fixedly installed at one end of the worm 9. The operating handle drives the rotation of the worm 9, which enables the worm gear 8 to precisely control the rotation of the threaded sleeve 7. In turn, the positions of the upper adjusting block 401 and the lower adjusting block 402 can be adjusted via the first threaded rod 6.
[0028] Please see Figure 1, Figure 3 and Figure 5 A first limiting rod 10 is fixedly installed on the top of the upper adjusting block 401. The outer surface of the middle part of the first limiting rod 10 is slidably connected to the inner wall of the middle part of the support frame 11. The first limiting rod 10 can restrict the movement direction of the upper adjusting block 401, prevent the upper adjusting block 401 from shifting during the adjustment process, and ensure that the cleaning felt 405 always maintains the correct relative position with the steel belt.
[0029] Please see Figure 1 , Figure 2 and Figure 5 A fixing plate 5 is fixedly installed at one end of the insert plate 404. The fixing plate 5 is fixedly installed at the end of the mounting plate 403 by fastening bolts. The cooperation between the fixing plate 5 and the fastening bolts allows the insert plate 404 to be stably installed on the mounting plate 403, ensuring the stability of the cleaning felt 405 during operation. At the same time, when the cleaning felt 405 needs to be replaced due to dirt, the insert plate 404 can be removed simply by unscrewing the fastening bolts, realizing the quick replacement of the cleaning felt 405 and significantly improving work efficiency.
[0030] Please see Figure 1 , Figure 2 and Figure 6 The end of the degreasing roller 2 is rotatably mounted on the inner wall of one end of the swing rod 12 via a rotating shaft. The inner wall of the other end of the swing rod 12 is hinged to the top of the base 1 via a hinge frame. The swing rods 12 corresponding to the upper and lower degreasing rollers 2 are symmetrically arranged. The hinge structure of the swing rod 12 allows the degreasing roller 2 to flexibly adjust its angle and position according to the thickness of the steel strip, ensuring that the degreasing roller 2 is in close contact with the surface of the steel strip and improving the degreasing effect. At the same time, this structure will not interfere with the replacement of the cleaning felt 405, ensuring the continuity of the overall operation of the equipment.
[0031] Please see Figure 1 , Figure 3 and Figure 6 An electric push rod 15 is fixedly mounted on the top of the base 1 via a support plate. A push plate 14 is fixedly mounted on the output end of the electric push rod 15. Two slide rods 13 are fixedly mounted on both ends of the top of the push plate 14 via support plates. The outer surface of the middle part of the slide rod 13 is slidably mounted in the inner wall of the groove opened in the middle of the swing rod 12. The electric push rod 15 pushes the push plate 14, which can drive the slide rod 13 to slide in the groove in the middle of the corresponding swing rod 12, thereby driving the swing rod 12 to swing. This allows for convenient adjustment of the distance between the two degreasing rollers 2.
[0032] Example 2: A steel strip degreasing device, please refer to [link / reference]. Figure 2 , Figure 3 and Figure 4The bottom of the two sets of limiting rollers 3 are rotatably mounted on the top of the two connecting plates 16 via a rotating shaft. The inner wall of the middle part of the two connecting plates 16 is threaded to the outer surface of the middle two sides of the second threaded rod 17. The outer surfaces of both ends of the second threaded rod 17 are rotatably mounted on the top of the base 1 via two support plates. One end of the second threaded rod 17 is provided with an operating handle. The thread directions of the outer surfaces of the middle two sides of the second threaded rod 17 are opposite. The thread direction of the outer surfaces of the middle two sides of the second threaded rod 17 is adapted to the thread direction of the inner wall of the middle part of the two connecting plates 16. Rotating the second threaded rod 17 can drive the two connecting plates 16 to move relative to or in opposite directions, thereby adjusting the distance between the two sets of limiting rollers 3 to adapt to steel strips of different widths, ensuring that the steel strip does not shift during the degreasing process, and improving the stability of degreasing and cleaning.
[0033] Please see Figure 2 , Figure 3 and Figure 4 The inner walls of both ends of the connecting plate 16 are slidably disposed on the outer surface of one side of the middle of the two second limiting rods 18. The two ends of the second limiting rods 18 are fixedly disposed on the top of the base 1 by two support plates. The second limiting rods 18 can limit the movement direction of the connecting plate 16, prevent the connecting plate 16 from rotating or shifting during the adjustment process, and ensure that the limiting roller 3 always maintains the correct position.
[0034] The implementation principle of this application embodiment is as follows: The electric push rod 15 operates, driving the push plate 14 to gradually move away from the oil removal roller 2, causing the slide rod 13 to slide within the groove of the swing rod 12, thus causing the swing rod 12 to swing. This causes the two oil removal rollers 2 to gradually move away from each other, increasing the distance between them. The steel strip to be degreased is then passed between the two oil removal rollers 2. The electric push rod 15 pushes the push plate 14 to gradually move towards the oil removal roller 2, causing the slide rod 13, in conjunction with the swing rod 12, to drive the two oil removal rollers 2 to gradually move closer together, reducing the distance between them. This ensures that the two oil removal rollers 2 are tightly attached to the upper and lower outer surfaces of the steel strip, and the conveying of the steel strip facilitates the degreasing process. Roller 2 initially removes large pieces of rolling oil or other oil stains and impurities adhering to the upper and lower outer surfaces of the steel strip. Based on the width of the steel strip, the operating handle at one end of the second threaded rod 17 is rotated, causing the second threaded rod 17 to rotate. The second threaded rod 17 drives the two connecting plates 16 to move in opposite directions, adjusting the distance between the two sets of limiting rollers 3 so that the two sets of limiting rollers 3 are tightly attached to both sides of the steel strip, preventing displacement of the steel strip during conveying. The operating handle of one set of cleaning components 4 corresponding to the worm gear 9 is rotated, causing the worm gear 9 to rotate, which in turn drives the corresponding worm wheel 8 to rotate. The worm wheel 8 then drives the corresponding threaded sleeve 7 to rotate, causing the thread... The sleeve 7, in conjunction with the first threaded rod 6, drives the upper adjusting block 401 and the lower adjusting block 402 to move vertically, adjusting the height of the bottom surface of the cleaning felt 405 corresponding to the upper adjusting block 401. The height of the bottom surface of the cleaning felt 405 is adapted to the upper surface of the steel belt being conveyed. The hydraulic rod 21 operates, driving the lower adjusting block 402 to move upward, which in turn drives the cleaning felt 405 corresponding to the lower adjusting block 402 to move upward. This allows the two cleaning felts 405 corresponding to the upper and lower adjusting blocks 401 and 402 to work together to clean the upper and lower surfaces of the steel belt by removing oil. After being cleaned by the cleaning felts 405, the steel belt enters the upper and lower thickness inspection sections. Between the sensors 20, the thickness of the steel strip after cleaning is detected to determine the cleaning status. When the cleaning felt 405 of the cleaning component 4 becomes dirty, the position of the cleaning felt 405 of the other cleaning component 4 is adjusted so that the cleaning felt 405 of the other cleaning component 4 can clean the steel strip by removing oil. By rotating the worm gear 9 in conjunction with the hydraulic rod 21, the two dirty cleaning felts 405 are moved away from the steel strip. The fastening bolts on the fixing plate 5 corresponding to the cleaning felt 405 are removed to release the fixation of the dirty cleaning felt 405. The insert plate 404 of the dirty cleaning felt 405 is pulled out from the corresponding mounting plate 403 for replacement.
