Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and more specifically, to an oil removal device. Background Technology

[0002] In the non-ferrous metals processing industry, especially in the cold rolling of copper strip, a large amount of lubricating oil is typically used during the rolling process to reduce friction, dissipate heat, and improve surface finish. However, after the coil is formed, due to capillary effect and gravity, these lubricating oils form difficult-to-remove residual oil areas on the sides and between layers of the copper strip. This leads to oxidation on the sides and edges of the copper strip within a depth of about 2 cm during the annealing process, severely affecting the subsequent cleaning effect and yield.

[0003] Existing degreasing devices typically employ the traditional static draining method, which is not only time-consuming but also inefficient, with minimal effect on removing deeply penetrated oil. Degreasing devices using mechanical contact scrapers or brushes can only treat the surface oil film, failing to address residual oil in the inner layers and easily damaging the copper strip surface. Furthermore, while common blowing degreasing methods can prevent oil overflow to some extent, limitations in vent layout and blowing force often prevent complete coverage, resulting in uneven airflow to the sides of the copper strip during rotation, leaving some residual oil behind and leading to poor degreasing efficiency. This, in turn, affects subsequent annealing and cleaning processes, reducing the yield. Utility Model Content

[0004] The main purpose of this utility model is to provide an oil removal device that can solve the problems of long oil removal time, inability to clean residual oil in the inner layer, low oil removal efficiency, and poor oil removal effect of existing oil removal devices.

[0005] To achieve the above objectives, according to one aspect of the present invention, an oil removal device is provided, comprising an oil collection hood, a rotating module, a negative pressure module, and a purging module. The rotating module includes a drive unit and a rotating shaft, with a roll of material sleeved on the rotating shaft. An oil collection space is formed inside the oil collection hood, and the roll of material is disposed within the oil collection space. The drive unit is driven and connected to the rotating shaft. The negative pressure module includes a negative pressure device, the suction end of which is connected to the oil collection hood. The purging module includes an air knife, which is disposed on the oil collection hood.

[0006] Furthermore, the oil removal device also includes a first mounting base, on which an oil collection hood is mounted.

[0007] Furthermore, the oil removal device includes a second mounting base, a rotating shaft rotatably mounted on the second mounting base, a first end of the rotating shaft connected to a drive unit, the rotating shaft passing through an oil collection cover, and a second end of the rotating shaft rotatably connected to a first mounting base.

[0008] Furthermore, the rotary module also includes a reduction mechanism, the input end of which is connected to the drive end of the drive unit, and the output end of which is connected to the first end of the rotary shaft.

[0009] Furthermore, the oil collection hood has an opening on the side facing the negative pressure device, or the oil collection hood has a cover plate on the side facing the negative pressure device, a sleeve is provided on the second mounting base, the sleeve is connected to the cover plate, a negative pressure channel is provided inside the sleeve, the negative pressure channel is connected to the oil collection space, the negative pressure device is connected to the sleeve, and the suction end of the negative pressure device is connected to the negative pressure channel.

[0010] Furthermore, the negative pressure device includes a negative pressure fan, which is capable of generating a negative pressure of -500Pa to -1500Pa.

[0011] Furthermore, a guide plate is provided on the inner wall of the oil collection hood, which can guide the oil sludge to the suction end of the negative pressure device.

[0012] Furthermore, the discharge end of the negative pressure device is equipped with a separator and an oil collection tank. The separator can separate the oil and transport the oil to the oil collection tank.

[0013] Furthermore, air knives are installed on the oil collection hood, with multiple air knives spaced apart circumferentially along the oil collection hood.

[0014] Furthermore, a photoelectric encoder is also installed at the end of the rotating shaft near the roll material, which can monitor the rotation speed and position of the roll material.

[0015] Furthermore, the oil removal device also includes a control system, which is communicatively connected to the drive unit, photoelectric encoder, and negative pressure device.

[0016] The technical solution of this utility model utilizes a drive unit, such as a servo motor, to provide power for the rotation of the roll material, precisely controlling the rotational speed of the rotating shaft to ensure efficient removal of residual oil from the surface and inner layers of the roll material using centrifugal force without damaging the roll material. The rotating shaft is responsible for fixing the roll material and fully transmitting the rotational force of the drive unit to the roll material to make it rotate. An oil collection hood surrounds the roll material to form a limited oil collection space, thereby concentrating the oil sludge blown away by the air knife and the oil sludge detached under the centrifugal force of rotation into the oil collection space. This helps reduce the diffusion of oil mist during the degreasing process, avoids oil loss, protects the workshop working environment from pollution, and creates conditions for the efficient suction of the negative pressure device. The air knife blows away the residual oil on the surface of the roll material through high-pressure airflow and peels the residual oil off the surface of the roll material. Negative pressure devices, such as negative pressure pumps or negative pressure fans, are used to generate a negative pressure environment to suck up the oil sludge centrifugally thrown from the roll material or blown off by the air knife, preventing the diffusion of oil mist and pollution of the workshop environment, while improving the oil recovery rate. Compared to existing oil removal devices that rely on static draining, mechanical scraping, or simply blowing to remove oil, this solution, by incorporating an oil removal device including an oil collection hood, a rotating module, a negative pressure module, and a blowing module, can effectively remove oil stains from the inner layer of the roll material. The oil collection hood confines the oil mist to a limited area, and the negative pressure device promptly sucks away and collects the oil stains, thereby achieving higher oil removal efficiency and better oil removal effect. This solves the problems of long oil removal time, inability to clean residual oil in the inner layer, low oil removal efficiency, and poor oil removal effect of existing oil removal devices.

[0022] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] See also Figures 1 to 2 As shown, this utility model provides an oil removal device, including an oil collection hood 5, a rotating module, a negative pressure module, and a purging module. The rotating module includes a drive unit 11 and a rotating shaft 12. A roll of material 4 is sleeved on the rotating shaft 12. An oil collection space 24 is formed inside the oil collection hood 5. The roll of material 4 is disposed in the oil collection space 24. The drive unit 11 is drivenly connected to the rotating shaft 12. The negative pressure module includes a negative pressure device 21. The suction end of the negative pressure device 21 is connected to the oil collection hood 5. The purging module includes an air knife 31, which is disposed on the oil collection hood 5.

[0024] In the above technical solution, for example, a drive unit 11, such as a servo motor, is used to provide power for the rotation of the roll material, precisely control the rotation speed of the rotating shaft 12, and ensure that residual oil on the surface and inner layer of the roll material is efficiently removed by centrifugal force without damaging the roll material 4. The roll material 4 includes a copper coil, and the rotating shaft 12 is responsible for fixing the roll material 4 and fully transmitting the rotational force of the drive unit 11 to the roll material 4 to make it rotate. The oil collection hood 5 surrounds the roll material 4 to form a limited oil collection space 24, thereby concentrating the oil stains blown away by the air knife 31 and the oil stains detached under the centrifugal force of rotation into the oil collection space 24, which helps to reduce the diffusion of oil mist during the degreasing process, avoid oil loss, protect the workshop working environment from pollution, and create conditions for the efficient suction of the negative pressure device 21. The air knife 31 blows away the residual oil on the surface of the roll material 4 through high-pressure airflow and peels the residual oil off the surface of the roll material. For example, negative pressure devices such as negative pressure pumps or negative pressure fans are used to create a negative pressure environment to suck up oil stains that are centrifugally thrown off the roll 4 or blown down by the air knife 31, preventing oil mist from spreading and polluting the workshop environment, while improving the oil recycling rate.

[0025] Compared to existing oil removal devices that rely on static draining, mechanical scraping, or simply blowing to remove oil, this solution, by incorporating an oil removal device including an oil collection hood 5, a rotating module, a negative pressure module, and a blowing module, can effectively remove oil stains from the inner layer of the roll material. The oil collection hood 5 confines the oil mist to a limited area, and the negative pressure device promptly sucks away and collects the oil stains, thereby achieving higher oil removal efficiency and better oil removal effect. This solves the problems of long oil removal time, inability to clean residual oil in the inner layer, low oil removal efficiency, and poor oil removal effect of existing oil removal devices.

[0026] In one embodiment of the present invention, the oil removal device further includes a first mounting base 6, and an oil collection cover 5 is disposed on the first mounting base 6.

[0027] In the above technical solution, the first mounting base 6 is used to provide a foundation for the installation and support of the oil collection hood 5. The oil collection hood 5 is fixedly installed on the first mounting base 6 to ensure that the oil collection hood 5 remains stable throughout the oil removal process and will not deviate from the predetermined position due to external forces or equipment vibration.

[0028] In one embodiment of the present invention, the oil removal device includes a second mounting base 7, a rotating shaft 12 is rotatably mounted on the second mounting base 7, the first end of the rotating shaft 12 is connected to the drive unit 11, the rotating shaft 12 passes through the oil collection cover 5, and the second end of the rotating shaft 12 is rotatably connected to the first mounting base 6.

[0029] In the above technical solution, the second mounting base 7 provides stable support for the rotating shaft 12 and the roll material 4 mounted on the rotating shaft 12. For example, a drive unit 11, such as a servo motor, provides power for the rotation of the roll material 4. The first end of the rotating shaft 12 is connected to the drive unit 11, thereby transmitting the rotational force generated by the drive unit 11 to the roll material 4, causing the roll material 4 to rotate at high speed. This ensures that the roll material 4 generates sufficient centrifugal force during rotation to throw residual oil out from the side. Simultaneously, the roll material 4 is located within the oil collection space 24, allowing the thrown-out oil mist to directly enter the oil collection space 24, preventing oil mist from splashing everywhere. Through the drive unit 11, such as a motor or servo system, the rotation speed of the roll material 4 can be controlled according to different characteristics of the roll material 4 and the residual oil situation, optimizing the oil removal effect and ensuring the controllability and efficiency of the oil removal process. The rotating shaft 12 is mounted on the second mounting base 7 and rotates relative to the second mounting base 7. The second end of the rotating shaft 12 passes through the oil collection cover 5 and is rotatably connected to the first mounting base 6 through rotating support components such as bearings. This allows the second mounting base 7 and the first mounting base 6 to provide support for the rotating shaft 12 from both sides of the roll 4, improving the strength and reliability of the rotating shaft 12 in supporting the roll 4. This prevents the rotating shaft 12 from bending, becoming eccentric, or even breaking under the heavy pressure of the roll 4, thus ensuring the structural strength of the rotating shaft 12 and its stability during high-speed rotation. It also prevents the shaft from generating excessive vibration or offset during rotation, which would affect the oil removal effect.

[0030] In one embodiment of the present invention, the rotation module further includes a reduction mechanism 13, the input end of the reduction mechanism 13 is connected to the driving end of the driving part 11, and the output end of the reduction mechanism 13 is connected to the first end of the rotation shaft 12.

[0031] In the above technical solution, the reduction mechanism 13 is located between the drive unit 11 and the rotating shaft 12, and can convert the higher speed provided by the drive unit 11 into the optimal speed suitable for degreasing the roll material 4. This speed conversion is not a simple reduction, but a dynamic adjustment based on the characteristics of the roll material 4, such as material hardness, thickness, and width, as well as the degree and amount of oil adhesion, to ensure efficient removal of residual oil while avoiding unnecessary mechanical stress on the roll material 4, preventing surface damage or material deformation. The input end of the reduction mechanism 13 is connected to the drive end of the drive unit 11, and the output end is connected to the first end of the rotating shaft 12, ensuring smooth speed transmission after reduction. This connection reduces energy loss in intermediate links, improves the overall system's energy efficiency ratio, and achieves high efficiency in power transmission and flexible control.

[0032] In one embodiment of this utility model, the oil collection cover 5 is open on the side facing the negative pressure device 21, or the oil collection cover 5 is provided with a cover plate on the side facing the negative pressure device 21, a sleeve 71 is provided on the second mounting base 7, the sleeve 71 is connected to the cover plate, a negative pressure channel is provided inside the sleeve 71, the negative pressure channel is connected to the oil collection space 24, the negative pressure device 21 is connected to the sleeve 71, and the suction end of the negative pressure device 21 is connected to the negative pressure channel.

[0033] In the above technical solution, when the oil collection hood 5 opens towards the negative pressure device 21, the roll material can be disassembled and assembled from the opening side, improving the disassembly and assembly efficiency of the roll material. The suction port of the negative pressure device 21 covers both sides and the bottom of the copper strip. In addition, since the oil collection hood 5 opens towards the negative pressure device 21, the negative pressure device 21 can adjust the negative pressure adsorption position at any time according to the oil accumulation in the oil collection hood 5 without being obstructed, thus having greater flexibility. The adjusted negative pressure device can then target the oil accumulation location for suction, improving the accuracy and efficiency of negative pressure adsorption.

[0034] When the oil collection hood 5 is fitted with a cover plate facing the negative pressure device 21, the cover plate design on the side of the oil collection hood 5 facing the negative pressure device 21 can fit tightly with the oil collection hood 5 to form a closed oil collection space. This closed design prevents oil mist and oil droplets generated during the oil removal process from escaping into the environment, reducing pollution to the workshop air, protecting the health of operators, and also providing a more effective negative pressure environment for the negative pressure device 21, improving the efficiency of oil mist collection. The sleeve 71 supports the rotating shaft 12 through bearings and other support components, allowing the rotating shaft 12 to rotate within the sleeve 71, connecting the drive unit 11 and the roll material 4 inside the oil collection hood. At the same time, a negative pressure channel is provided inside the sleeve 71, ensuring that oil mist and oil droplets in the oil collection hood 5 can be quickly drawn into the negative pressure device 21 through the negative pressure channel, avoiding secondary pollution caused by oil droplets remaining in the oil collection space 24, and improving the immediacy and efficiency of oil collection. By forming a relatively closed oil collection space 24 and a negative pressure channel, a stable and sufficient negative pressure is generated in the oil removal device, thereby improving the efficiency and effectiveness of oil mist collection.

[0035] In one embodiment of this utility model, the negative pressure device 21 includes a negative pressure fan, which is capable of generating a negative pressure of -500Pa to -1500Pa.

[0036] In the above technical solution, the negative pressure fan is the core component of the negative pressure device 21. It generates directional negative pressure to rapidly draw oil mist from the oil collection space 24, preventing the oil mist from spreading into the workshop air, protecting the cleanliness of the working environment, and reducing oil waste. The high-efficiency suction capacity of the negative pressure fan, combined with the closed design of the oil collection hood 5, forms a closed-loop oil mist collection system, significantly improving the oil recovery rate. The negative pressure generated by the negative pressure fan, ranging from -500Pa to -1500Pa, is designed to effectively draw and capture oil mist ejected from the side of the roll 4, while avoiding excessive negative pressure that could cause physical damage to the roll 4, ensuring that the oil removal process is carried out without compromising the integrity of the roll 4. The lower negative pressure of -500Pa is suitable for scenarios with less residual oil or where the roll 4 is more sensitive, while the higher negative pressure of -1500Pa is suitable for situations with more severe oil contamination, enabling more thorough oil removal and improving oil removal efficiency.

[0037] In one embodiment of this utility model, a guide plate 8 is provided on the inner wall of the oil collection cover 5, which can guide the oil to the suction end of the negative pressure device 21.

[0038] In the above technical solution, the oil collection hood 5 is an arc-shaped oil suction hood. A guide plate 8 is installed inside the oil collection hood 5, mainly utilizing fluid dynamics principles to guide the oil mist towards the suction end of the negative pressure device 21. This promotes effective accumulation of the oil mist at the suction end of the negative pressure device 21, reduces the residence time of the oil mist in the oil collection space 24, and lowers the probability of the oil mist re-adhering to the surface of the roll material 4 or the inner wall of the oil collection hood 5, thereby improving the recovery efficiency. Specifically, when a cover plate is provided on the side of the oil collection hood 5 facing the negative pressure device 21, the guide plate 8 can be installed on the oil collection hood 5 or on the cover plate. The arc-shaped guide plate 8 guides the airflow in the oil collection space 24 between the cover plate and the roll material to the negative pressure channel connected to the center of the cover plate, further improving the oil mist collection efficiency of the oil removal device.

[0039] In one embodiment of this utility model, the discharge end of the negative pressure device 21 is provided with a separator 22 and an oil collection tank 23. The separator 22 can separate oil and transport the oil to the oil collection tank 23.

[0040] In the above technical solution, the separator 22 is located at the discharge end of the negative pressure device 21. Its main task is to separate oil droplets from oily gas and convert oil mist into recyclable liquid oil. The separator 22 typically employs physical or chemical methods such as inertial separation, centrifugal separation, filtration, and electrostatic adsorption to separate oil mist from air, or a combination of multiple separation methods to form a multi-stage separation process. The oil separated by the separator 22 is collected in the oil collection tank 23 for unified treatment and reuse. The design of the oil collection tank 23 must consider the oil's storage capacity, cleanliness, and ease of subsequent processing. The oil collection tank 23 can not only serve as a temporary storage container but can also be equipped with filtration or purification devices to further improve the purity of the recovered oil, providing high-quality raw materials for subsequent oil reuse or resource recycling. When the separator adopts a multi-stage separation scheme combining electrostatic adsorption and a filter screen, the oil recovery rate is ≥90%.

[0041] The separator 22 and the oil collection tank 23 work together to form a highly efficient oil mist recovery and treatment system. The separator 22 is responsible for separating oil droplets from the oil mist, while the oil collection tank 23 is responsible for collecting and storing these oil droplets. The combination of the two enables the entire oil removal device to not only efficiently remove oil stains from the roll material 4, but also to achieve the recycling of oil, which greatly improves resource utilization, reduces production costs, and also reduces the oil content of the exhaust gas, thus reducing pollution to the atmospheric environment.

[0042] In one embodiment of this utility model, the air knife 31 is disposed on the oil collection cover 5, and multiple air knives 31 are arranged at intervals along the circumference of the oil collection cover 5.

[0043] In the above technical solution, the air knives 31 are spaced circumferentially along the oil collection hood 5, forming a continuous yet segmented blowing ring. As the roll material 4 rotates, each air knife 31 blows high-pressure air onto a specific area on the side of the roll material 4 at a specific time. This arrangement ensures the uniformity and comprehensiveness of the blowing process, avoids blind spots that may occur with a single air knife 31, and improves the efficiency and effectiveness of oil removal. The arrangement of multiple air knives 31 not only increases the blowing area but also forms a dynamic cleaning process through the interval blowing between the air knives 31. After one air knife 31 blows, the next air knife 31 can continue to blow away the oil mist that the previous air knife 31 could not completely remove. This relay blowing method makes the oil removal more thorough. At the same time, the interval setting also reduces mutual interference between the air knives 31, improves the blowing accuracy, and further improves the cleaning efficiency and effectiveness of the roll material. The air knife 31 is installed on the oil collection hood 5 and fits tightly with the structure of the oil collection hood 5. This ensures that the blown oil mist can be confined within the oil collection space of the oil collection hood 5. The negative pressure device draws and collects the oil mist to prevent its spread in the workshop, thus protecting the working environment. At the same time, it also improves the efficiency of oil mist recovery and reduces resource waste.

[0044] In one embodiment of this utility model, the air knife 31 is provided with an air blowing port facing the roll material 4. The distance between the air blowing port and the roll material 4 is 10mm~30mm. The pressure of the gas injected from the air blowing port is 0.5MPa~1.2MPa. The angle between the direction of the air jet from the air blowing port and the surface of the roll material 4 is 20°~45°.

[0045] In the above technical solution, if the distance between the air outlet and the roll material 4 is too close, the airflow may directly impact the surface of the roll material 4, causing unnecessary vibration or damage. If the distance is too far, the impact force of the airflow on the oil stains will be reduced, affecting the cleaning effect. A distance of 10mm to 30mm can ensure that the airflow has sufficient impact force while avoiding damage to the roll material 4, achieving the purpose of effectively cleaning the oil stains. High-pressure gas injection can form a strong shock wave, effectively peeling off and blowing away the oil film on the side of the roll material 4. However, excessive pressure will increase energy consumption and may also damage the roll material 4. Setting the injection gas pressure of the air outlet in the pressure range of 0.5MPa to 1.2MPa is a balance point that ensures the oil removal effect while taking into account energy efficiency and the safety of the roll material 4. If the angle between the direction of the airflow from the air outlet and the surface of the roll material 4 is too small, the airflow will slide along the surface of the roll material 4 and will not be able to effectively clean the oil stains. If the angle is too large, the impact force of the airflow on the side of the roll material 4 will be too large, causing damage to the roll material. An angle of 20° to 45° ensures that the airflow directly impacts the oil stains on all four sides of the roll material, while also ensuring that the airflow diffuses and covers the entire area of ​​all four sides of the roll material, thus improving the uniformity and thoroughness of oil stain removal.

[0046] By optimizing the spacing of the air nozzles, gas pressure, and injection angle, the air knife 31 in this embodiment can efficiently disperse oil stains on the side of the roll material 4. Simultaneously, in conjunction with the closed collection of the oil collection hood 5 and the immediate suction of the negative pressure device 21, a complete side oil removal system is formed. This design not only improves oil removal efficiency and reduces oil residue, but also reduces energy consumption and avoids damage to the roll material 4 by precisely controlling the air blowing parameters.

[0047] In one embodiment of this utility model, the air knife 31 includes annular porous air knives, which are respectively disposed on both sides of the coil to effectively disperse the residual oil film on the coil. The air knife adopts a micro-pore array with a pore diameter of 0.8mm~1.5mm, so that the airflow direction of the air knife is evenly distributed, and the airflow in any direction can maintain a relatively concentrated impact energy, ensuring that the residual oil film is effectively dispersed while avoiding damage to the surface of the copper strip.

[0048] In one embodiment of this utility model, a photoelectric encoder is also provided at one end of the rotating shaft 12 near the roll 4. The photoelectric encoder can monitor the rotation speed and position of the roll 4.

[0049] In the above technical solution, the photoelectric encoder is a high-precision position and speed sensor that converts the rotation angle and speed of the roll 4 into electrical signals for real-time reading and processing by control systems such as PLCs. This sensor typically consists of a light source, an encoder disk, and a photoelectric receiver. The encoder disk is engraved with stripes or holes representing position information. When the roll 4 rotates, causing the encoder disk to rotate, the photoelectric receiver can capture changes in the stripes or holes, thereby calculating the rotational speed and specific position of the roll 4. The real-time monitoring capability of the photoelectric encoder allows the control system to accurately grasp the state of the roll 4's rotation at every moment, including the speed and position. This information is crucial for adjusting the blowing angle of the air knife 31, the negative pressure intensity of the negative pressure device 21, and the working cycle of the entire degreasing device. Based on the data fed back by the photoelectric encoder, the control system can automatically adjust the parameters of each device according to the actual rotation of the roll 4, ensuring that the degreasing operation is performed under optimal conditions, improving degreasing efficiency and cleaning effect, while also avoiding excessive resource consumption.

[0050] The real-time monitoring data provided by the photoelectric encoder can also serve as a basis for diagnosing the operating status of the degreasing device. For example, when the rotation speed of roll 4 is abnormal or its position is off, the control system can immediately detect and adjust or issue an alarm, avoiding degreasing failure or damage to roll 4 due to equipment malfunction, reducing unpredictable risks in the production process, and improving the operational safety of the equipment.

[0051] In one embodiment of the present invention, the oil removal device further includes a control system, which is communicatively connected to the drive unit 11, the photoelectric encoder, and the negative pressure device 21.

[0052] In the above technical solution, the control system typically includes a controller such as a PLC and a control panel with a human-machine interface. The control system is communicatively connected to the drive unit 11, the photoelectric encoder, and the negative pressure device 21, aiming to achieve automated and intelligent control of the entire degreasing device to improve degreasing efficiency, ensure degreasing quality, and optimize energy use. Specifically, the communication connection between the control system and the drive unit 11 allows it to dynamically adjust the drive power according to the actual needs of the roll material 4, ensuring that the rotating shaft 12 operates at the optimal speed while reducing unnecessary energy consumption. This real-time power adjustment mechanism can adapt to the needs of different types and thicknesses of roll materials 4, improving the adaptability and flexibility of the equipment. The communication connection between the control system and the photoelectric encoder allows for precise monitoring of the motion state of the roll material 4, including its position and rotation speed, and dynamic optimization of the degreasing process based on this data. For example, when the rotation speed of the roll material 4 changes, the control system can promptly adjust the blowing parameters of the air knife 31 and the negative pressure intensity of the negative pressure device 21 to ensure that the blowing and oil suction operations are synchronized with the movement of the roll material 4, improving the efficiency and effectiveness of oil removal. The control system is connected to the negative pressure device 21 and can adjust the working parameters of the negative pressure device 21 in a timely manner according to the state of the roll material 4 and the operation of the oil removal device. This ensures that oil mist and oil droplets can be effectively adsorbed and collected, reducing the spread of oil and protecting the working environment, while also improving the oil recovery rate.

[0053] Through communication connections between the control system and the drive unit 11, photoelectric encoder, and negative pressure device 21, the oil removal device of this invention achieves fully automated control of the entire process, from efficient removal of oil stains from the roll material 4 to intelligent collection and treatment of oil stains. This design not only improves the oil removal effect and production efficiency but also reduces production costs and environmental pollution, reflecting the pursuit of intelligent, green manufacturing and efficient resource utilization in modern industrial production.

[0054] In one embodiment of this invention, the control system has preset multiple process curves for different roll material specifications and states, such as "high-speed thin strip" and "low-speed thick roll". Specifically, for thinner roll materials, the control rotation module uses a higher rotation speed to improve the degreasing effect of the roll material. For thicker roll materials with larger overall volume or weight, the control rotation module uses a lower rotation speed to ensure the safety of the device and the roll material.

[0055] In one embodiment of this utility model, the control system also has real-time monitoring and fault diagnosis functions. The fault diagnosis algorithm built into the control system can quickly identify the types of faults that may occur in the equipment based on the changing trends of the monitoring data, such as abnormal power of the drive unit 11, blockage of the air knife 31, and performance degradation of the negative pressure device 21. Once a potential fault is detected, the control system can immediately issue an early warning and notify the operator to take measures to prevent the fault from escalating and ensure the continuous operation of the equipment. In addition, it can also provide fault handling suggestions to guide the operator or maintenance team to quickly locate and repair the fault, reduce downtime and maintenance costs, thereby improving the controllability and efficiency of the degreasing process and reducing production costs and maintenance difficulty.

[0056] In one embodiment of this invention, the rotating shaft is a double-headed conical tensioning shaft, capable of tensioning within the roll at the center of the roll material, thereby achieving a fixed connection between the roll material and the double-headed conical tensioning shaft. The drive unit 11, including a servo motor, can drive the double-headed conical tensioning shaft and the roll material on it to rotate at an adjustable speed of 200 r / min to 800 r / min, generating centrifugal force to fling out residual oil from the inner layer of the roll material. The surface of the double-headed conical tensioning shaft is covered with a polyurethane wear-resistant layer to prevent scratching the inner hole of the roll material at the center.

[0057] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: For example, the drive unit 11, such as the servo motor, provides power for the rotation of the roll material, precisely controls the rotation speed of the rotating shaft 12, and ensures that the residual oil on the surface and inner layer of the roll material is efficiently removed by centrifugal force without damaging the roll material 4. The rotating shaft 12 is responsible for fixing the roll material 4 and fully transmitting the rotational force of the drive unit 11 to the roll material 4 to make it rotate. The oil collection hood 5 surrounds the roll material 4 to form a limited oil collection space 24, thereby concentrating the oil stains blown away by the air knife 31 and the oil stains detached under the action of rotation and centrifugal force in the oil collection space 24, which helps to reduce the diffusion of oil mist during the degreasing process, avoid oil loss, protect the workshop working environment from pollution, and at the same time create conditions for the efficient suction of the negative pressure device 21. The air knife 31 blows away the residual oil on the surface of the roll material 4 through high-pressure airflow and peels the residual oil off the surface of the roll material. For example, negative pressure devices such as negative pressure pumps or negative pressure fans are used to create a negative pressure environment to suck up oil stains that are centrifugally thrown off the roll 4 or blown down by the air knife 31, preventing oil mist from spreading and polluting the workshop environment, while improving the oil recycling rate.

[0058] Compared to existing oil removal devices that rely on static draining, mechanical scraping, or simple blowing, this solution, through an oil removal device including an oil collection hood 5, a rotating module, a negative pressure module, and a blowing module, can effectively remove oil stains from the inner layer of the copper coil, increasing the residual oil removal rate to over 95%, and ensuring no oxidation on the sides of the copper strip after annealing. By setting up the oil collection hood 5 to confine the oil mist to a limited area, combined with the negative pressure device to promptly suck away and collect the oil stains, higher oil removal efficiency and better oil removal effect are achieved, solving the problems of long oil removal time, inability to clean inner layer residual oil, low oil removal efficiency, and poor oil removal effect of existing oil removal devices. Furthermore, the yield is significantly improved, the scrap rate due to oxidation decreases by 3%~5%, and subsequent cleaning costs are saved by approximately 20%. The closed-loop negative pressure oil suction prevents oil mist from escaping, and the recovered rolling oil can be filtered and reused, reducing raw material consumption. The entire machine is controlled by a PLC program; operators only need to load and start the coil, reducing labor intensity by over 50%, and achieving a high degree of automation. By replacing the tensioning shaft and adjusting the angle of the air knife, it can be used for side degreasing of rolled copper coils such as aluminum strip and stainless steel strip, and has strong adaptability.
