Description

Technical Field

[0001] This invention relates to the field of metal processing equipment, and more particularly to a leveling machine for steel strip processing lines and its method of use. Background Technology

[0002] In modern industrial production, steel strip, as an important raw material, is used in multiple fields. During the production and processing of steel strip, its surface quality has a crucial impact on the final performance and service life of the product. During the production process, due to unavoidable factors in rolling, cutting, and transportation, various defects such as waviness, curling, scratches, and iron oxide scale will appear on the surface of the steel strip. These defects will reduce the mechanical and processing properties of the steel strip, and may even lead to quality problems such as breakage and deformation during subsequent use. Therefore, steel strip leveling is an indispensable part of the steel strip production and processing process. Through leveling, unevenness and defects on the surface of the steel strip can be eliminated, improving the surface quality and mechanical properties of the steel strip, providing a solid material foundation for subsequent processing and use.

[0003] Currently, various steel strip leveling equipment are available on the market, among which the leveling machine is the most commonly used. The leveling machine uses leveling rollers to compress the steel strip, making its surface smoother and flatter. Leveling rollers are typically made of high-hardness alloy steel, possessing excellent properties such as wear resistance and corrosion resistance. During the leveling process, enormous pressure is generated between the leveling rollers and the steel strip, causing plastic deformation of the steel strip surface, thereby achieving the purpose of leveling.

[0004] However, due to the multiple processing steps involved in the steel strip process, various impurities and defects may exist on the surface, such as debris generated during steel strip cutting, dust in the air, and iron oxide scale on the steel strip itself. When these impurities come into contact with the leveling roller, they can cause damage or contamination. After prolonged operation, wear, scratches, and even cracks may appear on the surface of the leveling roller, which will not only reduce the leveling effect but also affect the service life of the leveling roller. Summary of the Invention

[0005] To overcome the shortcomings of insufficient cleaning and equipment damage caused by impurities, this invention provides a leveling machine with cleaning function for steel strip processing lines and a method of using it.

[0006] A leveling machine for a steel strip processing line includes a mounting shell, leveling rollers, a mounting assembly, and a power assembly. The mounting shell houses the mounting assembly and the power assembly. Two leveling rollers are rotatably connected inside the mounting shell via the mounting assembly. The power assembly drives the leveling rollers. The machine also includes mounting plates, inner tubes, outer tubes, sealing covers, an extraction mechanism, a cleaning mechanism, a collection assembly, and a shielding assembly. Mounting plates are connected to both sides of the front end of the mounting shell, and two inner tubes are connected between the mounting plates. An outer tube is fixedly connected to the outside of the inner tubes. Sealing covers are located on both sides of the mounting plates, and these covers engage with the outer tubes. An extraction mechanism for removing dust adhering to the surface of the steel strip is located inside the outer tube, and a cleaning mechanism for cleaning the steel strip is located outside the outer tube. A collection assembly for collecting impurities is located inside the inner tube, and a shielding assembly is installed on the collection assembly to seal it.

[0007] Furthermore, the collection component includes a placement square tube, a collection frame, and a limiting pin. The placement square tube is connected inside the inner tube, and the collection frame is slidably connected inside the placement square tube. A limiting hole is provided inside the sealing cover, and a limiting pin is slidably connected to the end of the collection frame. The limiting pin and the limiting hole are inserted into each other.

[0008] Furthermore, the extraction mechanism includes a motor, an output shaft, a multi-section pulley assembly, an installation tube, an air inlet pipe, a mounting frame, fan blades, a drive shaft, and a flat-top cone. The motor is mounted on the placement square tube, which is connected to several installation tubes, and the installation tubes are connected to the placement square tube. The top of the motor is connected to the output shaft, and the top of the installation tube is connected to the mounting frame. The mounting frame is rotatably connected to the drive shaft. The output shaft and several drive shafts are connected by a multi-section pulley assembly. The drive shaft is mounted on the fan blades, and the lower end of the drive shaft is connected to the flat-top cone. The lower end of the flat-top cone has a smaller diameter. One end of the air inlet pipe is connected to the side of the installation tube, and the air inlet pipe passes through the inner and outer pipes in the middle. The other end is close to the steel belt that is conveyed backward.

[0009] Furthermore, the cleaning mechanism includes a bevel gear set, fixed blocks, a multi-section transmission gear shaft, a gear ring, and brush heads. Several fixed blocks are connected to the outer side of the inner tube, and the multi-section transmission gear shaft is rotatably connected to the fixed blocks. A bevel gear set is connected to the end of the multi-section transmission gear shaft and the top of the output shaft. The motor drives the multi-section transmission gear shaft through the output shaft and the bevel gear set. A gear ring is rotatably connected to the outer tube. The inner ring of the gear ring meshes with the multi-section transmission gear shaft, and several brush heads are connected to the outer ring of the gear ring. The brush heads contact the steel belt.

[0010] Furthermore, the shielding assembly includes a wedge block, a rack block, a roller, a guide rod, a drive wheel, a rotating shaft, baffles, and a torsion spring. The left end of the collection frame is connected to a wedge block, and the left end of the inner tube is connected to a guide rod. The guide rod is slidably connected to two rack blocks. A roller is rotatably connected to an adjacent side of the rack block. The roller and the wedge block are pressed together. Rotating shafts are rotatably connected to the front and rear sides of the square tube. A drive wheel is connected to the left end of the rotating shaft. The drive wheel meshes with the rack block. Several baffles are connected to the rotating shaft. The baffles contact the bottom of the mounting tube. A torsion spring is sleeved on the rotating shaft. One end of the torsion spring is connected to the rotating shaft, and the other end is connected to the square tube.

[0011] Furthermore, it also includes a filter screen, which is connected inside the mounting tube and located below the fan blades.

[0012] Furthermore, it also includes a handle; a handle is attached to the right end of the collection box.

[0013] The specific operating steps for using a leveling machine on a steel strip processing line are as follows:

[0014] S1. Turn on the leveling machine and let the steel belt pass through the leveling machine;

[0015] S2. Turn on the motor. The motor drives the fan blades through a multi-section pulley set. Impurities are sucked in through the air intake pipe. The motor drives the gear ring through a multi-section transmission gear shaft. The brush head cleans the impurities on the surface of the steel belt and works in conjunction with the air intake pipe.

[0016] S3. Impurities enter the installation pipe through the air inlet pipe and fall into the collection box. The staff opens the sealing cover, takes out the limit pin, pulls out the collection box, and pours out the impurities inside. When the collection box moves, the torsion spring rotates the baffle to seal the bottom of the installation pipe.

[0017] S4. Push the collection box in, twist the torsion spring, and continue to collect impurities.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. The brush head removes impurities from the surface of the steel strip, and the extraction and collection components draw in and collect the removed impurities and gas from the surface of the steel strip, thereby achieving efficient cleaning of the steel strip surface and centralized collection and treatment of impurities, ultimately protecting the leveling roller and extending its service life.

[0020] 2. Through the cooperation of the shielding component and the collecting component, the bottom of the installation tube is automatically closed and opened during the process of pulling out and pushing in the collecting frame, so as to continuously collect impurities and keep the leveling machine working normally.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example: A leveling machine used in a steel strip processing line, such as Figures 1-10 As shown, the assembly includes a mounting housing 1, leveling rollers 11, a mounting assembly 12, and a power assembly 13. The mounting housing 1 is equipped with the mounting assembly 12 and the power assembly 13. Two leveling rollers 11 are rotatably connected inside the mounting housing 1 via the mounting assembly 12. The distance between the two leveling rollers 11 can be adjusted via the mounting assembly 12 to level steel strips of different thicknesses. The power assembly 13 drives the leveling rollers 11, and the two leveling rollers 11 rotate in opposite directions. The assembly also includes a mounting plate 2, an inner tube 3, an outer tube 4, a sealing cover 5, an extraction mechanism 6, a cleaning mechanism 7, a collection assembly 8, and a shielding assembly 9. Mounting plates 2 are connected to both sides of the front end of the mounting housing 1. Two inner tubes 3 are connected between the mounting plates 2, and an outer tube 4 is fixedly connected to the outside of the inner tubes 3. Sealing covers 5 are provided on both sides of the mounting plate 2, and the sealing covers 5 are engaged with the outer tubes 4. In conjunction with this, the outer tube 4 is equipped with an extraction mechanism 6 for removing dust adhering to the surface of the steel strip. The extraction mechanism 6 mainly includes an installation tube 64 and an air inlet tube 65. The air inlet tube 65 is close to the steel strip, and when air is extracted, a negative pressure is formed on the surface of the steel strip, sucking in impurities from the surface of the steel strip. The outer tube 4 is equipped with a cleaning mechanism 7 for cleaning the steel strip. The cleaning mechanism 7 mainly includes a brush head 75. The rotating brush head 75 directly contacts the steel strip and is used to brush away impurities from the surface of the steel strip. The inner tube 3 is equipped with a collection component 8 for collecting impurities. The collection component 8 mainly includes a collection frame 82. The sliding collection frame 82 is used to collect impurities falling from the installation tube 64. The collection component 8 is equipped with a shielding component 9 for sealing the collection component 8. The shielding component 9 mainly includes a baffle 97. The baffle 97 is used to temporarily seal the installation tube 64 from the bottom to prevent impurities from falling.

[0034] like Figure 3 , Figure 5 , Figure 8 and Figure 9 As shown, the collection assembly 8 also includes a placement square tube 81, a limiting pin 83, and a handle 85. Each inner tube 3 is connected to a placement square tube 81. The collection frame 82 is slidably connected inside the placement square tube 81. The sealing cover 5 is provided with two limiting holes 84. The end of the collection frame 82 is slidably connected to the limiting pin 83. The limiting pin 83 is inserted into the limiting hole 84 of the sealing cover 5 and is an interference fit. The right end of the collection frame 82 is connected to a handle 85.

[0035] like Figure 5 and Figure 6As shown, the extraction mechanism 6 also includes a motor 61, an output shaft 62, a multi-section pulley assembly 63, a mounting bracket 66, fan blades 67, a drive shaft 68, a flat-top cone 69, and fan blades 67. The motor 61 is mounted on the placement square tube 81. Each placement square tube 81 is connected to eight mounting tubes 64, which are located on the same straight line. The bottom of all mounting tubes 64 are connected to the placement square tube 81. The top of the motor 61 is connected to the output shaft 62, and the top of the mounting tubes 64 is connected to the mounting bracket 66. The drive shaft 68 is rotatably connected to the middle of the mounting bracket 66. The output shaft 62 and the drive shaft 68 are also connected to the drive shaft 69. The drive shafts 68 are connected by a multi-section pulley group 63, which consists of pulleys and belts that transmit power to each other. A fan blade 67 is installed on the drive shaft 68. A flat-top cone 69 is connected to the lower end of the drive shaft 68. The lower end of the flat-top cone 69 has a smaller diameter. One end of the air intake pipe 65 is connected to the side of the mounting pipe 64. The air intake pipe 65 passes through the inner pipe 3 and the outer pipe 4 in the middle. The other end is close to the steel belt that is conveyed backward and is funnel-shaped to increase the air intake area. A filter screen 610 is connected inside the mounting pipe 64 and is located below the fan blade 67.

[0036] like Figure 7 As shown, the cleaning mechanism 7 also includes a bevel gear set 71, a fixing block 72, a multi-section transmission gear shaft 73, and a gear ring 74. Fourteen fixing blocks 72 are connected to the top of each inner tube 3. All fixing blocks 72 are rotatably connected to the multi-section transmission gear shaft 73. Seven gears are provided on each multi-section transmission gear shaft 73. Two fixing blocks 72 are provided on both sides of each gear. The end of the multi-section transmission gear shaft 73 is connected to the top of the output shaft 62 via a bevel gear set 71. The motor 61 drives the multi-section transmission gear shaft 73 through the output shaft 62 and the bevel gear set 71. Seven gear rings 74 are rotatably connected to the outer tube 4. The inner ring of each gear ring 74 meshes with the gears of the multi-section transmission gear shaft 73. Ten brush heads 75 are connected to the outer ring of the gear ring 74. The brush heads 75 are in contact with the steel belt. The design allows the brush heads 75 on two adjacent gear rings 74 to be staggered.

[0037] like Figure 8 and Figure 10As shown, the shielding assembly 9 also includes a wedge block 91, a rack block 92, a roller 93, a guide rod 94, a transmission wheel 95, a rotating shaft 96, and a torsion spring 98. The left end of the collection frame 82 is connected to the wedge block 91, and the left end of the inner tube 3 is connected to two guide rods 94. The guide rods 94 are slidably connected to two rack blocks 92. The adjacent side of the two rack blocks 92 is rotatably connected to the roller 93. The roller 93 and the wedge block 91 are pressed together. The front and rear sides of the placement square tube 81 are rotatably connected to the rotating shaft 96. The left end of the rotating shaft 96 is connected to the transmission wheel 95. The transmission wheel 95 meshes with the rack block 92. Eight baffles 97 are connected to the rotating shaft 96. The baffles 97 are in contact with the bottom of the mounting tube 64. A torsion spring 98 is sleeved on the rotating shaft 96. One end of the torsion spring 98 is connected to the rotating shaft 96, and the other end is connected to the placement square tube 81.

[0038] The operator turns on the power unit 13 to drive the leveling roller 11 to rotate, thereby leveling the passing steel strip. Before the steel strip contacts the leveling roller 11, the impurities on the surface of the steel strip are scraped off by the brush head 75 of the cleaning component and sucked into the collection frame 82 of the collection component 8 through the air inlet pipe 65 of the extraction component. During the operation of the leveling roller 11, the collection frame 82 can also be pulled out to clean the impurities inside. When the collection frame 82 is pulled out, the baffle 97 of the blocking component 9 will block the impurities from falling from the installation pipe 64. After the collection frame 82 is inserted, the blocking component 9 is opened again, thus continuing to work and ensuring the cleaning of the steel strip, thereby protecting the leveling roller 11 from damage.

[0039] After the motor 61 is turned on, the motor 61 drives all the transmission shafts 68 through the output shaft 62 and the multi-section pulley group 63. The multi-section pulley group 63 is composed of multiple interconnected pulleys and belts. Except for the transmission shaft 68 at the end, each transmission shaft 68 is connected to two pulleys. The transmission shaft 68 drives the fan blade 67 to rotate, thereby drawing out the gas in the mounting tube 64. The gas flows along the air inlet pipe 65 to the mounting tube 64, thereby collecting the gas on the surface of the steel strip. The impurities cleaned by the brush head 75 follow the flowing gas into the air inlet pipe 65, and then into the mounting tube 64. The gas passes through the filter screen 610, and the impurities are blocked by the filter screen 610. Moreover, the impurities entering the mounting tube 64 fall into the collection frame 82 after hitting the flat top cone 69. The top and bottom of the steel strip are provided with air inlet pipes 65 and brush heads 75, thereby cleaning the steel strip on both sides and protecting the flat roller 11.

[0040] The output shaft 62 of the motor 61 drives the multi-section transmission gear shaft 73 to rotate through the bevel gear set 71. The bevel gear set 71 consists of two meshing bevel gears. The multi-section transmission gear shaft 73 is equipped with multiple gears, each of which meshes with a gear ring 74. Thus, the multi-section transmission gear shaft 73 drives multiple gear rings 74 to rotate. Multiple brush heads 75 are connected to the outside of the gear rings 74. The brush heads 75 continuously clean the surface of the steel strip, brushing away impurities such as oxide scale debris and dust. The brushed-away impurities follow the airflow into the air intake pipe 65 and are collected by the collection frame 82.

[0041] When cleaning the collection frame 82, open the sealing cover 5, take out the limiting pin 83 inserted in the limiting hole 84, and pull out the collection frame 82 through the handle 85 on the side of the collection frame 82. When the collection frame 82 moves outward, the baffle 97 blocks the installation tube 64 upward to prevent impurities from falling. After the worker pulls out the collection frame 82, he pours out the impurities collected inside and pushes it back into the placement square tube 81. When the collection frame 82 is completely pushed into the placement square tube 81, the wedge block 91 and the roller 93 re-engage, and the baffle 97 is reset through the transmission mechanism, allowing impurities to continue falling into the collection frame 82.

[0042] As the collection frame 82 moves outward, the wedge block 91 disengages from the roller 93 assembly, the torsion spring 98 twists, and the rotating shaft 96 rotates, causing the baffles 97 on both sides to rotate towards the center. The rotating shaft 96 drives the transmission wheel 95 to rotate, which in turn moves the rack blocks 92 on both sides towards the center. The roller 93 remains in contact with the wedge block 91. As the collection frame 82 moves, the wedge block 91 completely disengages from the roller 93. At this point, the torsion spring 98 causes the rotating shaft 96 to rotate 90 degrees. After the two baffles 97 rotate 90 degrees, they contact the bottom of the mounting tube 64, preventing impurities from falling down. Furthermore, the baffles 97 do not affect the collection frame 82 from pulling out the square tube 81 for collection. During the process of pushing the frame 82 in, the horizontal baffle 97 will not obstruct the collection frame 82. When the collection frame 82 is fully inserted into the placement square tube 81, the wedge block 91 and the roller 93 are pressed together. The roller 93 pushes the rack blocks 92 on both sides to slide along the guide rod 94, thereby driving the transmission wheel 95 to rotate. The transmission wheel 95 rotates the rotational force towards the rotating shaft 96, and at the same time, the torsion spring 98 is torn, causing the baffle 97 to rotate. The baffle 97 is separated from the bottom of the mounting tube 64. After rotating 90 degrees, it fits against the side of the collection frame 82. The blocked impurities fall into the collection frame 82. The fixed collection frame 82 can also stabilize the state of the baffle 97 and continuously collect impurities.

[0043] When the leveling machine starts, the power unit 13 drives the leveling roller 11 to rotate, performing leveling operations on the passing steel strip. Before this, the motor 61 synchronously drives a series of transmission shafts 68 through a multi-section pulley set 63. The fan blades 67 on these transmission shafts 68 rotate accordingly, generating suction, which draws in gas and impurities from the surface of the steel strip through the air intake pipe 65. At the same time, the output shaft 62 of the motor 61 is also connected to a multi-section transmission gear shaft 73 via a bevel gear set 71. Multiple gears on this shaft mesh with a gear ring 74, driving the gear ring 74 and its brush head 75 to rotate. The brush head 75 makes close contact with the surface of the steel strip, effectively removing oxide scale, dust, and other impurities. These brushed impurities enter the air intake pipe 65 with the airflow, and then fall into the collection frame 82 through the mounting pipe 64. The filter screen 610 inside the mounting pipe 64 effectively intercepts impurities, ensuring smooth gas discharge. The collection frame 82 is designed for easy replacement and cleaning. It is fixed to the square tube 81 by a limiting pin 83. When the collection frame 82 is pulled out, the wedge block 91 separates from the roller 93 assembly, triggering the torsion spring 98 to drive the rotating shaft 96 to rotate, causing the baffle 97 to rotate to the position of the bottom of the sealing mounting tube 64 to prevent impurities from scattering. When the collection frame 82 is pushed back into place, the wedge block 91 engages with the roller 93 again, and the baffle 97 is reset through the transmission mechanism, allowing new impurities to fall into the collection frame 82.

[0044] The specific steps for using a leveling machine on a steel strip processing line are as follows:

[0045] S1. Turn on the leveling machine and let the steel belt pass through the leveling machine;

[0046] S2. Start the motor 61. The motor 61 drives the fan blade 67 through the multi-section pulley group 63, and sucks in impurities through the air intake pipe 65. The motor 61 drives the gear ring 74 through the multi-section transmission gear shaft 73, and cleans the impurities on the surface of the steel belt through the brush head 75, working in conjunction with the air intake pipe 65.

[0047] S3. Impurities enter the installation pipe 64 through the air inlet pipe 65 and fall into the collection frame 82. The staff opens the sealing cover 5, takes out the limit pin 83, pulls out the collection frame 82, and pours out the impurities inside. When the collection frame 82 moves, the torsion spring 98 rotates the baffle 97 to seal the bottom of the installation pipe 64.

[0048] S4. Push in the collection box 82, twist the torsion spring 98, and continuously collect impurities.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
