Description

Technical Field

[0001] This utility model relates to the technical field of strip steel processing equipment, specifically to a single-fiber roller wiping device for wiping emulsion residue on the surface of strip steel. Background Technology

[0002] In the production and processing of strip steel, emulsions are commonly used, playing important roles in lubrication, cooling, and cleaning during rolling. However, during rolling and coiling, emulsion residue often remains on the strip surface. This residue, when rolled between coil layers, forms emulsion spots on the strip and causes slippage during coiling. The more residue, the greater the risk of coil collapse during coiling. To address these issues, a three-roller extrusion device is typically used to extrude the strip. The effectiveness of this device depends primarily on the overlap between the upper two rolls and the lower roll, adjusted by a height regulating screw. A larger overlap results in better extrusion, and vice versa. When high surface quality and shape requirements are demanding for the strip, the overlap must be reduced, leading to a significantly worse extrusion effect and increased emulsion residue on the strip surface. Therefore, this problem is overcome by adding a single-fiber roller wiping device. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a single-fiber roller wiping device for wiping emulsion residue on the surface of strip steel. The fiber roller can follow the strip steel to rotate passively, thereby wiping the emulsion on the surface of the strip steel and significantly reducing the emulsion residue on the surface of the strip steel.

[0004] The technical solution adopted in this utility model is a single-fiber roller wiping device for wiping emulsion residue on the surface of steel strip. It includes a main body of the single-fiber roller wiping device, comprising a fiber roller. A fixed shaft passes through the inside of the fiber roller. Both ends of the fixed shaft extend into supporting columns on both sides and connect to a first bearing. The first bearing is fixed in a bearing seat, which is located within a receiving cavity in the supporting column. A first sliding rod is connected to the back of the bearing seat. The first sliding rod connects to a first sliding block in a sliding groove. The sliding groove is fixed to one side wall inside the receiving cavity. A bearing seat connecting plate is fixed to the top of the base. The top of the bearing seat connecting plate is fixed to the telescopic rod of the cylinder. The cylinder is mounted on the cylinder base plate. The cylinder base plate is fixed to the connecting positioning plate. The connecting positioning plate is fixed to the top of the support columns on both sides. The bottom of the support columns is fixed to the fixed base plate. The bottom of the fixed base plate is fixed with a support leg. An adjustment limit device is installed in the receiving cavity inside the support column on one side. A controller is installed on the outer wall of the support column with the adjustment limit device. A limit fixing device is installed on the bottom of the fixed base plate next to the adjustment limit device.

[0005] The adjusting and limiting device includes an internally threaded sleeve located at the bottom of the receiving cavity. The internally threaded sleeve is internally threaded and connected to an adjusting screw. The top of the adjusting screw is connected to a short rotating rod. The short rotating rod is connected to a second bearing. The second bearing is embedded in the bottom of the limiting lifting seat. A pressure sensor is embedded on the top of the limiting lifting seat. A second sliding rod is connected to one side of the limiting lifting seat. The second sliding rod is connected to a second slider in a sliding groove. A scale is fixed on the other side wall inside the receiving cavity. The bottom end of the adjusting screw passes through a support column and a fixed base plate and is fixedly connected to a rotating handle.

[0006] The limiting and fixing device includes an electric push rod fixed to the bottom of the fixed base plate. The electric push rod is connected to one side of the lifting plate, and an electromagnet is installed on the other side of the lifting plate. The electromagnet can attract and rotate the handle.

[0007] The telescopic rod of the cylinder passes through the cylinder base plate, the positioning plate and the support column in sequence. The cylinder base plate is fixed to the positioning plate by the first fixing bolt, and the positioning plate is fixed to the support column by the second fixing bolt.

[0008] The bearing housing connecting plate is fixed to the bearing housing by a third fixing bolt.

[0009] The supporting column has a limiting hole on the side facing the fiber roller, and a fixed shaft passes through the limiting hole. The supporting column with the adjusting limiting device has an observation window on the front.

[0010] The controller has control buttons installed on the front cabinet door. The controller contains an STM processor module. The control buttons are electrically connected to the STM processor module and the electromagnet. The STM processor module is electrically connected to a pressure sensor, a cylinder, and an electric actuator.

[0011] The bearing housing is located above the limit lifting seat.

[0012] The beneficial effects of this utility model are as follows: In this utility model, a fiber roller is provided. The fiber roller can be raised and lowered under the combined action of the cylinder, bearing seat connecting plate, bearing seat, first bearing and fixed shaft. When the fiber roller descends and contacts the surface of the strip steel, it will follow the strip steel to rotate passively, thereby wiping the emulsion on the surface of the strip steel. Combined with on-site debugging, after adding a single fiber roller wiping device for wiping, the squeezing effect of the three-roll iron roller squeezing device is improved, and the emulsion residue on the surface of the strip steel is significantly reduced. It is suitable for various emulsion rolling mills or oil rolling mills.

[0013] In this invention, the structure of the fiber roller is better than that of the steel roller and the rubber roller, and has the advantages of better liquid flow control, more flexible driven rotation, repeated grinding and use, and the ability to form compressive stress on the surface of the strip steel.

[0014] In this invention, the adjustable limit device facilitates the adjustment and control of the descent height of the fiber roller; after debugging, the effect is best when the pressure of the fiber roller on the strip is 15-20mm.

[0015] In this invention, the electromagnet in the limiting and fixing device can attract the rotating handle in the adjusting limiting device, which facilitates the stabilization of the adjusting screw after it has been adjusted, and can prevent accidental contact that could cause the adjusting screw to rotate, thus benefiting the continuous production of the same batch of products.

[0023] Referring to the accompanying drawings, a single-fiber roller wiping device for wiping emulsion residue from the surface of steel strip includes a single-fiber roller wiping device body 1. The single-fiber roller wiping device body 1 includes a fiber roller 6. A fixed shaft 4 is fixedly passed through the fiber roller 6. The two ends of the fixed shaft 4 extend into the support columns 9 on both sides and are connected to a first bearing 8. The first bearing 8 is fixed in a bearing seat 13. The bearing seat 13 is located in a receiving cavity 7 within the support column 9. A first slide rod 16 is connected to the back of the bearing seat 13. The first slide rod 16 is connected to a first slider 14 in a sliding groove 17. The sliding groove 17 is fixed on one side wall inside the receiving cavity 7. The bearing seat 13 is topped with a first slide rod 16. A bearing seat connecting plate 12 is fixed at one end. The top of the bearing seat connecting plate 12 is fixedly connected to the telescopic rod of the cylinder 10. The cylinder 10 is mounted on the cylinder base plate 11. The cylinder base plate 11 is fixed on the connecting positioning plate 5. The connecting positioning plate 5 is fixed on the top of the support columns 9 on both sides. The bottom of the support column 9 is fixed on the fixed base plate 2. The bottom of the fixed base plate 2 is fixed with a support leg 3. An adjustment limiting device is installed in the receiving cavity 7 inside the support column 9 on one side. A controller 15 is installed on the outer wall of the support column 9 with the adjustment limiting device. A limiting fixing device is installed on the bottom of the fixed base plate 2 next to the adjustment limiting device.

[0024] The adjusting and limiting device includes an internally threaded sleeve 27 located at the bottom of the receiving cavity 7. The internally threaded sleeve 27 is internally threadedly connected to an adjusting screw 26. The top end of the adjusting screw 26 is connected to a short rotating rod 21. The short rotating rod 21 is connected to a second bearing 28. The second bearing 28 is embedded in the bottom of the limiting lifting seat 20. A pressure sensor 29 is embedded on the top of the limiting lifting seat 20. A second sliding rod 19 is connected to one side of the limiting lifting seat 20. The second sliding rod 19 is connected to a second slider 18 in a sliding groove 17. A scale 30 is fixed on the other side wall inside the receiving cavity 7. The bottom end of the adjusting screw 26 passes through the supporting column 9 and the fixed base plate 2 and is fixedly connected to a rotating handle 22.

[0025] The limiting and fixing device includes an electric push rod 25 fixed on the bottom of the fixed base plate 2. The electric push rod 25 is connected to one side of the lifting plate 24. An electromagnet 23 is installed on the other side of the lifting plate 24. The electromagnet 23 can attract and rotate the handle 22.

[0026] The telescopic rod of the cylinder 10 passes through the cylinder base plate 11, the positioning plate 5 and the support column 9 in sequence. The cylinder base plate 11 is fixed to the positioning plate 5 by the first fixing bolt 31, and the positioning plate 5 is fixed to the support column 9 by the second fixing bolt 32.

[0027] The bearing housing connecting plate 12 is fixed to the bearing housing 13 by the third fixing bolt 33.

[0028] The supporting column 9 has a limiting hole 34 on its side facing the fiber roller 6, and a fixed shaft 4 passes through the limiting hole 34. The supporting column 9 with the adjusting limiting device has an observation window 35 on its front side.

[0029] The controller 15 has control buttons installed on the front cabinet door. The controller 15 is equipped with an STM processor module. The control buttons are electrically connected to the STM processor module and the electromagnet 23. The STM processor module is electrically connected to the pressure sensor 29, the cylinder 10 and the electric push rod 25.

[0030] The bearing seat 13 is located above the limiting lifting seat 20.

[0031] The single-fiber roller wiping device, used to wipe the emulsion residue on the surface of the strip steel, is located inside the three-roll iron roll extrusion device 38. The strip steel 40 used for rolling is uncoiled from the right coil 41, and then enters the six-roll mill device 39 for rolling after passing through the right guide roller 37. After rolling, the strip steel 40 first passes through the main body 1 of the single-fiber roller wiping device, then through the three-roll iron roll extrusion device 38, and then through the left guide roller 37 before being wound up by the left coil 36.

[0032] When using the main body 1 of the single fiber roller wiping device, first rotate the handle 22 to make the adjusting screw 26 rotate in the internal thread sleeve 27 to realize the rise or fall of the limit lifting seat 20. Then observe the change of the lifting position of the limit lifting seat 20 through the observation window 34. When the top surface of the limit lifting seat 20 rises to the specified scale on the scale 30, stop rotating the handle 22 and start the electric push rod 25 through the control button on the controller 15. The electric push rod 25 drives the lifting plate 24 to rise. When the electromagnet 23 touches the bottom of the handle 22, turn off the electric push rod 25. Then start the electromagnet 23 to make the electromagnet 23 attract the handle 22 to prevent accidental collision that would cause the handle 22 to rotate again.

[0033] After the height of the limit lifting seat 20 is fixed, the cylinder 10 is activated. The cylinder 10 drives the bearing seat connecting plate 12 to move downward, causing the bearing seat 13 to move downward. The bearing seat 13 drives the first bearing 8 to move downward, causing the fixed shaft 4 to move, thereby causing the fiber roller 6 to move downward. When the bearing seat 13 touches the pressure sensor 29, the pressure sensor 29 will transmit a signal to the STM processor module in the controller 15. The STM processor module will control the cylinder 10 to stop extending, causing the bearing seat 13 to stop descending, thereby fixing the position of the fiber roller 6 and making the fiber roller 6 contact the surface of the strip steel 40. Driven by the strip steel 40, it will rotate passively, thereby wiping the emulsion on the strip steel 40.

[0034] In this invention, a fiber roller 6 is provided. The fiber roller 6 can be raised and lowered under the combined action of the cylinder 10, the bearing seat connecting plate 12, the bearing seat 13, the first bearing 8, and the fixed shaft 4. After the fiber roller 6 descends and contacts the surface of the strip steel 40, it will follow the strip steel 40 to rotate passively, thereby wiping the emulsion on the surface of the strip steel 40. Combined with on-site debugging, after adding a single fiber roller wiping device for wiping, the squeezing effect of the three-roller iron roller squeezing device is improved, and the emulsion residue on the surface of the strip steel 40 is significantly reduced. It is suitable for various emulsion rolling mills or oil rolling mills.

[0035] In this invention, the structure of the fiber roller 6 is better than that of the steel roller and rubber roller, and has advantages such as better liquid flow control, more flexible driven rotation, repeated grinding and use, and the formation of compressive stress on the surface of the strip steel 40.

[0036] In this invention, the adjustable limit device facilitates the adjustment and control of the descent height of the fiber roller 6; after debugging, the effect is best when the pressure of the fiber roller 6 on the strip 40 is 15-20mm.

[0037] In this invention, the electromagnet 23 in the limiting and fixing device can attract the rotating handle 22 in the adjusting limiting device, which facilitates the stabilization of the position of the adjusting screw 26 after it has been adjusted. This avoids accidental contact that could cause the adjusting screw 26 to rotate, and is beneficial for the continuous production of the same batch of products.

[0038] The above-described embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively describe all possible implementations.
