Description

Technical Field

[0001] This invention relates to the field of steel strip production and processing technology, and more specifically, to an oiling mechanism for steel strip production. Background Technology

[0002] In the production process of steel strip, in order to prevent the steel strip from rusting during storage and transportation, it is usually necessary to apply an oil coating to the surface of the steel strip, that is, to coat the surface of the steel strip with a uniform anti-rust oil film.

[0003] The existing methods for coating steel strips mainly include roller coating and spray coating.

[0004] Spray-type oiling atomizes the rust-preventive oil through nozzles and sprays it onto the surface of the steel strip or the oiling roller. However, this method suffers from oil mist dispersion, which not only wastes oil but also adversely affects the production environment and the health of operators. Furthermore, the oiling roller surface becomes completely coated with oil after being sprayed, and the oil easily drips off the roller, resulting in uneven application and equipment contamination.

[0005] Roller coating uses upper and lower coating rollers to apply oil from the oil tank to the steel strip. The entire circumference of the coating roller is covered with oil, and oil is continuously flowing out from the non-working side as well. This not only wastes oil but also results in poor coating uniformity.

[0006] The existing technologies described above have defects: the oiling roller is either fully coated or fully oiled, and the oil tends to drip off after the roller is saturated, resulting in oil waste. The oiling is uneven, the oil film thickness on the steel belt is uneven, which affects the anti-corrosion effect of the steel belt. The oil cost is high, the oil mist is scattered, the workshop is seriously polluted, and the oil mist also affects the health of the operators. Summary of the Invention

[0007] To address the above deficiencies, this invention provides an oiling mechanism for steel strip production, thereby solving the aforementioned problems.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: An oiling mechanism for steel strip production includes a fixed frame with a cover fixedly connected to the frame. The cover has an inlet and an outlet on its two sides. A hollow oiling roller is installed inside the cover, consisting of an upper oiling roller and a lower oiling roller. The steel strip passes between the upper and lower oiling rollers. The mechanism is characterized by an internal oil supply mechanism on the hollow oiling roller and an oil scraping mechanism inside the cover. The internal oil supply mechanism includes an oil outlet hole opened on the peripheral wall of the hollow oiling roller, an oil seepage layer is sleeved on the hollow oiling roller, an internal oil supply roller is provided inside the hollow oiling roller, an oil supply cavity is fixedly connected to the outer wall of the internal oil supply roller, a plurality of oil supply holes are provided at the communication between the peripheral wall of the internal oil supply roller and the oil supply cavity, and a sealing element is connected to the end of the oil supply cavity away from the internal oil supply roller, and the sealing element is in contact with the inner wall of the hollow oiling roller; The oil supply chamber forms a connected oil supply channel between the sealing element and the inner wall of the hollow oiling roller. The rust-preventive oil passes through the oil supply hole, the oil supply chamber and the oil outlet hole in sequence, and only seeps out from the oil outlet hole connected to the oil supply chamber and is coated on the surface of the steel strip through the seepage layer. No oil is produced from the oil outlet hole that is not connected to the oil supply chamber.

[0009] Furthermore, the oil-permeable layer is made of felt or non-woven fabric, and the sealant is made of wear-resistant rubber.

[0010] Furthermore, both ends of the hollow oiling roller are connected to hollow shafts via bearings, and fixed seats are connected to the hollow shafts. A linear drive element is installed inside the cover, and the output end of the linear drive element is fixedly connected to the fixed seat. Both ends of the inner oil supply roller extend into the corresponding hollow shafts, and the ends of the inner oil supply roller are fixedly connected to the inner wall of the hollow shaft via brackets.

[0011] Furthermore, the upper and lower oiling rollers are each equipped with the linear drive element and a corresponding fixed seat, and the two are independently fixedly connected to the corresponding hollow shaft to realize the independent lifting and lowering adjustment of the upper and lower hollow oiling rollers.

[0012] The gap between the hollow oiling roller and the strip is adjusted by a linear drive element, which facilitates fine-tuning and applying appropriate contact pressure to the strip. The roller spacing and oiling pressure can be flexibly adjusted according to different strip thicknesses and oiling processes, making it widely applicable.

[0013] Furthermore, the oil scraping mechanism includes an oil receiving box and a collection box. The oil receiving box is located below one side of the upper oiling roller. Both ends of the oil receiving box are fixedly connected to the inner wall of the cover. An upper oil scraper is provided inside the oil receiving box. The upper oil scraper is rotatably connected to the oil receiving box via an upper rotating shaft. The end of the upper oil scraper away from the oil receiving box is in contact with the oil seepage layer on the outer periphery of the upper oiling roller. The collection box is located below the lower oiling roller. The collection box is fixedly connected to the cover via a support block. A lower oil scraper is provided inside the collection box. The lower oil scraper is rotatably connected to the collection box via a lower rotating shaft. The end of the lower oil scraper away from the collection box is in contact with the oil seepage layer on the outer periphery of the lower oiling roller.

[0014] Excess oil on the seepage layer is scraped off by the upper and lower scraper blades, preventing the seepage layer from becoming saturated and dripping oil, avoiding an excessively thick oil film, and improving oil utilization.

[0015] Furthermore, a fixed shaft is fixedly connected inside the oil receiving box and the collection box. The fixed shaft is located below the side of the corresponding upper or lower oil scraper. Several spring seats are movably mounted on the fixed shaft. A spring is connected to the spring seat. One end of the spring is fixedly connected to the spring seat, and the other end of the spring is fixedly connected to the corresponding upper or lower oil scraper.

[0016] The spring force ensures that the upper or lower scraper blade remains in contact with the oil seepage layer, guaranteeing thorough oil removal and preventing damage to the oil seepage layer.

[0017] Furthermore, an oil storage tank is connected to the fixed frame, an oil pump is installed on the oil storage tank, an oil supply pipe is connected to the discharge end of the oil pump, a rotary joint is connected to one end of the inner oil supply roller, a flexible oil supply pipe is connected to the rotary joint, and the flexible oil supply pipe is fixedly connected to the oil supply pipe.

[0018] Furthermore, the oil receiving box is connected to a return oil pipe, the end of which extends into the collection box. The collection box is inclined by a support block, and the inclined end of the collection box is provided with an oil return port. A recovery pipe connects the oil return port to the oil storage tank.

[0019] The oil can be returned to the storage tank, and the rust-preventive oil can be reused, reducing production costs.

[0020] The beneficial effects of this invention are: Through the internal oil supply mechanism, the rust-preventive oil seeps into the oil-permeable layer through the internal oil supply roller, oil supply hole, oil supply chamber, and oil outlet hole. The oil-permeable layer then coats the rust-preventive oil onto the surface of the steel strip. The oil outlet hole, which is not connected to the oil supply chamber, is sealed and isolated, thus achieving directional oil supply, reducing ineffective oil supply, preventing the oil-permeable layer from becoming saturated and dripping, avoiding excessively thick oil film, and preventing oil dripping and waste. The oil quantity is controllable, the oil coating is uniform, and the thickness of the oil film coated on the steel strip surface is guaranteed to be uniform, improving the oil coating quality and the anti-corrosion performance of the steel strip. The oil does not pass through the air, so there is no oil mist or oil mist dispersion, which improves the environment and worker health. Attached Figure Description

[0022] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] This application provides an oiling mechanism for steel strip production. Please refer to [link / reference]. Figures 1-9 The machine includes a fixed frame 1, on which a cover 2 is fixedly connected. The cover 2 has an inlet 3 and an outlet 4 on its two sides. A hollow oiling roller is provided inside the cover 2. The hollow oiling roller is divided into an upper oiling roller 5 and a lower oiling roller 6. A steel strip passes between the upper oiling roller 5 and the lower oiling roller 6. The machine is characterized in that the hollow oiling roller is provided with an internal oil supply mechanism and the cover 2 is provided with an oil scraping mechanism. The internal oil supply mechanism includes an oil outlet hole 7 opened on the peripheral wall of the hollow oiling roller, an oil seepage layer 8 sleeved on the hollow oiling roller, an internal oil supply roller 9 inside the hollow oiling roller, an oil supply cavity 10 fixedly connected to the outer wall of the internal oil supply roller 9, a plurality of oil supply holes 11 provided at the connection between the peripheral wall of the internal oil supply roller 9 and the oil supply cavity 10, and a sealing element 12 connected to the end of the oil supply cavity 10 away from the internal oil supply roller 9, and the sealing element 12 is in contact with the inner wall of the hollow oiling roller; The oil supply chamber 10 forms a connected oil supply channel between the sealing element 12 and the inner wall of the hollow oiling roller. The rust-preventive oil passes through the oil supply hole 11, the oil supply chamber 10 and the oil outlet hole 7 in sequence, and only seeps out from the oil outlet hole 7 connected to the oil supply chamber 10 and is coated on the surface of the steel strip through the seepage layer 8. The oil outlet hole 7 that is not connected to the oil supply chamber 10 does not produce oil.

[0024] In practical applications, the steel strip passes horizontally between the upper oiling roller 5 and the lower oiling roller 6. Both rollers simultaneously apply oil to the upper and lower surfaces of the steel strip. The oil seepage layer 8 on the upper and lower oiling rollers 5 and 6 contacts the surface of the steel strip. As the steel strip is conveyed, the upper and lower oiling rollers 5 and 6 rotate, allowing the rust-preventive oil to enter the inner oil supply roller 9. The rust-preventive oil in the inner oil supply roller 9 enters the oil supply chamber 10 through the oil supply hole 11, and then enters the inner wall of the hollow oiling roller through the connecting oil supply channel, exiting at the point of connection with the oil supply chamber 10. Oil seeps out of hole 7 and enters the oil seepage layer 8, where the rust-preventive oil is coated onto the steel strip surface. The oil outlet hole 7, which is not connected to the oil supply chamber 10, does not discharge oil due to its sealed isolation, thus achieving directional oil supply, reducing ineffective oil supply, preventing the oil seepage layer from becoming saturated and dripping, avoiding excessively thick oil film, preventing oil dripping and waste, controlling the oil volume, ensuring uniform oil coating, and guaranteeing a uniform oil film thickness on the steel strip surface. This improves the oil coating quality and the corrosion resistance of the steel strip. The oil does not pass through air, so no oil mist is generated, and there is no oil mist dispersion, which improves the environment and worker health.

[0025] Refer to the instruction manual appendix Figure 7 The oil seepage layer 8 is made of felt or non-woven fabric, and the seal 12 is made of wear-resistant rubber.

[0026] In practical applications, the oil penetration layer 8 is made of felt or non-woven fabric, which can evenly distribute the oil to the entire working surface and ensure that the oil film thickness on the steel strip surface is uniform. The sealing element 12 is made of wear-resistant rubber, which not only ensures effective sealing with the inner wall of the hollow oiling roller, but also adapts to the friction when the hollow oiling roller rotates, ensuring stability and sealing reliability during long-term use.

[0027] Refer to the instruction manual appendix Figure 3 Instruction manual attached Figure 4 Included with instruction manual Figure 5 The hollow oiling roller has hollow shafts 14 connected to both ends of the hollow oiling roller via bearings 13. A fixed seat 15 is connected to the hollow shaft 14. A linear drive element 16 is installed inside the cover 2. The output end of the linear drive element 16 is fixedly connected to the fixed seat 15. The two ends of the inner oil supply roller 9 extend into the corresponding hollow shafts 14. The end of the inner oil supply roller 9 is fixedly connected to the inner wall of the hollow shaft 14 via a bracket 17. The upper oiling roller 5 and the lower oiling roller 6 are each provided with a linear drive element 16 and a corresponding fixed seat 15. The two are independently fixedly connected to the corresponding hollow shafts 14 to realize the independent lifting and lowering adjustment of the upper and lower hollow oiling rollers.

[0028] In practical applications, when the strip thickness changes, the linear drive element 16 can be activated by a cylinder, hydraulic cylinder, or electric push rod. The output end of the linear drive element 16 drives the hollow shaft 14 and the hollow oiling roller sleeved on it to move up and down through the fixed base 15, adjusting the gap between the hollow oiling roller and the strip. The upper oiling roller 5 and the lower oiling roller 6 are each independently equipped with a linear drive element 16, which can be raised and lowered separately, facilitating fine adjustment and applying appropriate contact pressure to the strip. The roller spacing and oiling pressure can be flexibly adjusted according to different strip thicknesses and oiling processes, making it widely applicable. The two ends of the hollow oiling roller are rotatably connected to the hollow shaft 14 via bearings 13. The two ends of the inner oil supply roller 9 extend into the corresponding hollow shaft 14. The end of the inner oil supply roller 9 is fixedly connected to the inner wall of the hollow shaft 14 through the bracket 17. Therefore, the hollow shaft 14 and the inner oil supply roller 9 are fixed and do not rotate. Only the hollow oiling roller rotates passively with the steel strip conveying, and the oil supply and rotation do not interfere with each other.

[0029] Refer to the instruction manual appendix Figure 2 Instruction manual attached Figure 8 Included with instruction manual Figure 9 The oil scraping mechanism includes an oil receiving box 18 and a collection box 19. The oil receiving box 18 is located below one side of the upper oiling roller 5. Both ends of the oil receiving box 18 are fixedly connected to the inner wall of the cover 2. An upper oil scraper 20 is provided inside the oil receiving box 18. The upper oil scraper 20 is rotatably connected to the oil receiving box 18 through an upper rotating shaft 21. The end of the upper oil scraper 20 away from the oil receiving box 18 is in contact with the oil seepage layer 8 on the outer periphery of the upper oiling roller 5. The collection box 19 is located below the lower oiling roller 6. The collection box 19 is fixedly connected to the cover 2 through a support block 22. A lower oil scraper 23 is provided inside the collection box 19. The lower oil scraper 23 is rotatably connected to the collection box 19 through a lower rotating shaft 24. The end of the lower oil scraper 23 away from the collection box 19 is in contact with the oil seepage layer 8 on the outer periphery of the lower oiling roller 6.

[0030] In practical applications, when the upper coating roller 5 rotates, the upper scraper 20 adheres to the oil seepage layer 8 on the surface of the upper coating roller 5, scraping off excess oil from the oil seepage layer 8. The scraped oil falls into the oil collection box 18. When the lower coating roller 6 rotates, the lower scraper 23 adheres to the oil seepage layer 8 on the surface of the lower coating roller 6, scraping off excess oil from the oil seepage layer 8. The scraped oil falls into the collection box 19. This process scrapes off excess oil from the oil seepage layer 8, preventing the oil seepage layer 8 from becoming saturated and dripping, avoiding an excessively thick oil film, and improving oil utilization.

[0031] Refer to the instruction manual appendix Figure 8 Included with instruction manual Figure 9A fixed shaft 25 is fixedly connected inside the oil receiving box 18 and the collection box 19. The fixed shaft 25 is located on the side and below the corresponding upper oil scraper 20 or lower oil scraper 23. Several spring seats 26 are movably mounted on the fixed shaft 25. Springs 27 are connected to the spring seats 26. One end of the spring 27 is fixedly connected to the spring seat 26, and the other end of the spring 27 is fixedly connected to the corresponding upper oil scraper 20 or lower oil scraper 23.

[0032] In practical applications, the upper scraper 20 or the lower scraper 23 floats and adheres to the surface of the oil seepage layer 8 under the force of the spring 27. After the upper oiling roller 5 and the lower oiling roller 6 move up and down, the upper scraper 20 or the lower scraper 23 can always adhere to the oil seepage layer 8 due to the floating and adhering of the spring 27, ensuring thorough oil removal and avoiding scratching the oil seepage layer 8.

[0033] Refer to the instruction manual appendix Figure 2 Included with instruction manual Figure 4 An oil storage tank 28 is connected to the fixed frame 1. An oil pump 29 is installed on the oil storage tank 28. An oil supply pipe 30 is connected to the discharge end of the oil pump 29. A rotary joint 31 is connected to one end of the inner oil supply roller 9. A flexible oil supply pipe 32 is connected to the rotary joint 31. The flexible oil supply pipe 32 is fixedly connected to the oil supply pipe 30.

[0034] In practical applications, the oil pump 29 extracts the anti-rust oil from the oil storage tank 28 and sends it through the oil supply pipe 30, the flexible oil supply pipe 32, and the rotary joint 31 into the inner oil supply roller 9.

[0035] Refer to the instruction manual appendix Figure 2 Instruction manual attached Figure 8 Included with instruction manual Figure 9 The oil receiving box 18 is connected to a return oil pipe 33. The end of the return oil pipe 33 extends into the collection box 19. The collection box 19 is set at an angle by a support block 22. The angled end of the collection box 19 is provided with an oil return port 34. A recovery pipe 35 is connected between the oil return port 34 and the oil storage tank 28.

[0036] In practical applications, the oil in the oil receiving box 18 flows into the collection box 19 through the return oil pipe 33. The collection box 19 is tilted so that the oil flows towards the tilted end. The oil flows back to the oil storage tank 28 through the return oil port 34 and the recovery pipe 35. The rust-preventive oil can be reused, which reduces production costs.
