In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it 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 directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] like Figure 1-Figure 7 As shown, a stainless steel belt straightening machine provided by an embodiment of the utility model includes a support seat 1, on which a plurality of tensioning rollers 11 are rotatably mounted, a support frame 2 is mounted in the middle of the support seat 1, and a lubrication assembly is mounted in the support frame 2, the lubrication assembly includes two groups of oil brush rollers 3 which are parallel to each other and arranged up and down, the two oil brush rollers 3 each include a bearing roller 31 and a roller brush 32 rotatably mounted on the outside of the bearing roller 31, the bearing roller 31 is fixedly mounted on the inner wall of the support frame 2, and the support frame 2 is also provided with a driving member 4, which drives the two roller brushes 32 to rotate relative to each other.

[0031] Furthermore, the rotation direction of the two roller brushes 32 is opposite to the conveying direction of the steel belt.

[0032] Furthermore, each roller brush 32 includes a cylindrical support and bristles 321 mounted on the support.

[0033] Specifically, Figure 1As shown, the tensioning roller 11 is the main component of the straightening machine, which is used to tension the steel strip and straighten it. The tensioning roller 11 is arranged on the left and right sides of the support frame 2. The specific method of the tensioning roller 11 is the existing technology and can be directly applied without further explanation. A lubrication component is arranged in the support frame 2, and the lubrication component includes two groups of oil brush rollers 3. The two groups of oil brush rollers 3 are parallel to each other and arranged up and down. When the steel strip is straightened, the steel strip passes between the two oil brush rollers 3, and the upper and lower surfaces of the steel strip can be evenly coated with lubricating oil. Among them, the bearing roller 31 is used to support the roller brush 32. The roller brush 32 includes a support member and bristles 321. The support member is cylindrical, and the bristles 321 are arranged along the circumference of the support member. The lubrication component also includes an oil supply component for soaking the bristles 321 with oil. A driving member 4 is also arranged on the support frame 2. The driving member 4 is used to drive the two roller brushes 32 to rotate relative to each other. The oil supply component and the driving member 4 are both existing technologies and can be directly applied without further explanation.

[0034] It should be noted that the axial length of the bristles 321 along the support is greater than the width of the steel belt, so that the upper and lower surfaces of the steel belt can be fully coated with lubricating oil. Obviously, in order to prevent the oil from being thrown out of the bristles 321 due to the action of centrifugal force, the rotation speed of the roller brush 32 can be slowed down to reduce the centrifugal force on the oil.

[0035] When the lubrication assembly is in use, the driving member 4 drives the roller brush 32 to rotate outside the bearing roller 31, and the bristles 321 on the supporting member are constantly in contact with the surface of the steel strip and apply lubricating oil to the upper and lower surfaces of the steel strip. Preferably, the rotation direction of the two brush rollers is opposite to the conveying direction of the steel strip, so that the steel strip is Figure 2 Taking the conveying from the left side to the right side in the view as an example, the roller brush 32 at the top rotates in a clockwise direction, while the roller brush 32 at the bottom rotates in a counterclockwise direction, thereby improving the brushing effect of the lubricating oil.

[0036] The stainless steel strip straightening machine provided by the embodiment of the utility model adopts a roller-shaped roller brush 32 to apply lubricating oil. The roller is driven to rotate, and its surface can continuously contact the surface of the steel strip, so that the oil is evenly brushed on the upper and lower surfaces of the steel strip. There will be no flowable oil on the surface of the steel strip, the pollution to the straightening machine is small, and there is no waste of oil.

[0037] In another embodiment of the utility model, a cleaning comb 21 with cleaning bristles 321 is provided at the position corresponding to the roller brush 32 in the support frame 2, and the ends of the cleaning comb 21 are inclined upward. When the brush roller is driven to rotate, the bristles 321 move from the upper direction of the cleaning comb 21 to the lower direction of the cleaning comb 21. A storage box 22 is also provided on the support frame 2, and the lower end of the cleaning comb 21 is provided inside the cleaning box.

[0038] Specifically, during the straightening process of the steel strip, due to the viscosity of the oil, dust and other impurities on the surface of the steel strip will adhere to the bristles 321, causing a certain impact on the subsequent brushing; in this embodiment, Figure 7 As shown, a cleaning comb 21 is provided in the support frame 2, the teeth of the cleaning comb 21 are inclined upward, and the cleaning comb 21 is arranged along the axial direction of the supporting roller 31. When the bristles 321 pass through the cleaning comb 21, a part of the impurities adhering to the bristles 321 will be combed out and stored in the storage box 22, so as to avoid excessive adhesion of impurities on the bristles 321, resulting in a reduction in the brushing effect of the oil transported later on the steel belt. Obviously, in order to facilitate the cleaning of the storage box 22, the storage box 22 can be detachably connected to the support frame 2, such as by mounting the storage box 22 on the support frame 2 by bolts.

[0039] In another embodiment of the utility model, a cylindrical cavity is provided inside the supporting roller 31, and an oil outlet 311 is provided circumferentially of the supporting roller 31 to connect the cavity to the root of the bristle 321, and an oil supply assembly is also provided on the support frame 2, and the oil pipe of the oil supply assembly is connected to the cavity.

[0040] Furthermore, the supporting members include two rotating rings 322 rotatably installed on the outside of the supporting roller 31, the two rotating rings 322 correspond to the two ends of the supporting roller 31 respectively, and a plurality of support columns 323 are arranged between the two rotating disks, and the plurality of support columns 323 are distributed in a circular array with the central axis of the rotating ring 322 as the center. The outer sleeve of the supporting roller 31 is provided with a cylindrical sponge cover 324, and the positions of the sponge cover 324 corresponding to the support columns 323 are all provided with perforations along its own axial direction, and the roots of the bristles 321 are all connected to the sponge cover 324.

[0041] Furthermore, the driving member 4 includes a motor 41 mounted on the support frame 2, a gear 42 is fixedly connected to the output end of the motor 41, a gear ring 43 is fixedly connected to the rotating ring 322, the gear ring 43 and the gear 42 are meshed with each other, and the rotating rings 322 at the same end of the two supporting members are connected through a belt 44.

[0042] Specifically, Figure 2 and Figure 3 As shown, the cavity in the supporting roller 31 is connected to the outside through the oil outlet 311, and in order to ensure that the bristles 321 are soaked in oil, a cylindrical sponge cover 324 is mounted on the outside of the supporting roller 31, and a plurality of support columns 323 are arranged along the axial direction of the sponge cover 324, so that when the rotating ring 322 drives the support columns 323 to rotate, the sponge cover 324 can be driven to rotate outside the supporting roller 31, and an oil filling port 312 is provided at one end of the supporting roller 31, and oil is continuously added into the cavity through the filling port to ensure sufficient oil supply.

[0043] When lubricating oil is applied to the surface of the steel belt, the oil in the cavity flows outward through the oil outlet 311, and the rotating ring 322 is driven to drive the support column 323, the sponge sleeve 324 and the bristles 321 to revolve around the central axis of the supporting roller 31. The corresponding part of the sponge sleeve 324 passes through the oil outlet 311, and the oil flowing out from the oil outlet 311 will first penetrate the sponge sleeve 324, and then flow to the bristles 321 due to the centrifugal force generated when the sponge sleeve 324 rotates, and finally is evenly applied to the surface of the steel belt by the bristles 321. The sponge sleeve 324 is provided to slow down the speed of the oil flowing outward, thereby avoiding excessive oil on the bristles 321.

[0044] In another embodiment of the present invention, a cylindrical oil supply pipe 313 is fixedly connected to the interior of the carrier roller 31 . The oil supply pipe 313 is fixedly connected to the inner wall of the carrier roller 31 , and the oil outlet 311 passes through the lower part of the oil supply pipe 313 .

[0045] Furthermore, the oil supply pipes 313 are all arranged inside the carrying rollers 31 and obliquely below the conveying direction of the steel strip.

[0046] Furthermore, a sponge strip 314 is disposed in the oil outlet 311 .

[0047] Specifically, since the bearing roller 31 is fixedly mounted on the support frame 2, in order to allow the bristles 321 to pass through the oil outlet 311 and be soaked in oil before contacting the surface of the steel strip, the oil outlet 311 needs to be located inside the bearing roller 31 and obliquely below the conveying direction of the steel strip, so that the steel strip can be conveyed by the oil outlet 311. Figure 2 and Figure 3 Taking the transportation from the left side to the right side in the view as an example, the oil outlet 311 needs to be opened at the lower right side of the supporting roller 31, which makes it difficult for the oil filled in the cavity to flow out of the cavity completely, and part of the oil will always remain in the lower part of the cavity; in this embodiment, by setting an oil supply pipe 313 in the supporting roller 31, one end of the oil supply pipe 313 is connected to the oil filling port 312 opened on the supporting roller 31 in the above embodiment, and the oil outlet 311 is connected to the inside of the oil supply pipe 313 by the side wall of the oil supply pipe 313, so that the oil can flow to the sponge sleeve 324. In order to further control the flow speed of the oil and prevent the sponge sleeve 324 from being thrown out due to excessive oil, a sponge strip 314 is provided in the oil outlet 311, and the sponge strip 314 is used to slow down the flow speed of the oil.

[0048] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
