Description

Technical Field

[0001] This utility model relates to the field of stamping lubrication, specifically to an automatic oiling and lubrication device based on intelligent control. Background Technology

[0002] In modern industrial manufacturing, aluminum is widely used in many industries such as automobile manufacturing and electronic equipment due to its excellent properties such as light weight, high strength, and corrosion resistance. With the improvement of industrial automation, progressive die stamping technology has been widely used in the field of aluminum processing due to its high efficiency and high precision.

[0003] Progressive dies (also known as continuous dies) are high-efficiency stamping dies that can complete multiple processes (such as punching, bending, forming, and cutting) in a single stroke. In the production of aluminum using progressive dies, due to the low surface hardness and high ductility of aluminum, it is prone to severe friction with the surface of the leveling machine and the die cavity during stamping deformation, leading to scratches, wear, and other quality defects that affect product quality. In this situation, lubrication is crucial to ensuring the quality of aluminum parts forming. Lubricating oil must be applied to the aluminum surface to form an isolation layer, reducing the coefficient of friction and minimizing the risk of scratches. A leveling machine (also known as a straightening machine or screed) is an industrial device used to correct unevenness on the surface of metal sheets, coils, or other materials. Its main function is to eliminate internal stress in the material through mechanical force, achieving a flat and smooth surface.

[0004] Currently, the common method for lubricating progressive die aluminum is operator application. However, this traditional method has the following problems: (1) Uneven oil control and serious oil waste: Since it relies entirely on the operator's subjective judgment and operating experience, it is difficult to accurately control the amount of lubricating oil applied, resulting in inconsistent oil film thickness. In areas with insufficient lubrication, the aluminum material cannot form an effective protective layer, and surface scratches, wear and other quality problems are prone to occur during the stamping process. In areas with excessive lubrication, the excess lubricating oil cannot be recycled, which not only wastes resources but also pollutes the working environment and increases subsequent cleaning costs. (2) Low efficiency: The operator's oiling speed is difficult to match with the operating rhythm of the leveling machine. This mismatch greatly limits the improvement of production efficiency. Utility Model Content

[0005] The present invention aims to provide an automatic oiling and lubrication device based on intelligent control to solve the problems of uneven oil quantity control and serious oil waste in the prior art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an automatic oiling and lubrication device based on intelligent control, comprising an oiling device installed at the discharge end of a gasket machine and a lubrication hydraulic system connected to the oiling device; the oiling device includes a fixed frame, with an oil chamber between the fixed frames, and an array of atomizing oil sprayers for spraying lubricating oil at the bottom of the oil chamber, and a regulating valve for adjusting the oil volume at the top of the oil chamber; below the atomizing oil sprayers are sequentially arranged upper felt rollers and lower felt rollers for applying lubricating oil to the surface of the aluminum material, which... The aluminum material is located between the upper felt roller and the lower felt roller. The atomized oil spray, the upper felt roller, and the lower felt roller work together to lubricate the aluminum material. The bottom of the fixing frame is inclined and equipped with an oil receiving box for collecting lubricating oil, and the oil receiving box is located below the lower felt roller. The lubrication hydraulic system includes an oil tank for storing lubricating oil. The oil receiving box is connected to the oil tank. The top of the oil tank is equipped with a hydraulic pump for transporting lubricating oil to the oil chamber. The oil chamber, the oil receiving box, and the oil tank form a closed loop circulation.

[0007] The principle of this solution is as follows: In practical application, the automatic oiling and lubrication device and the gasket machine are activated, and the hydraulic pump starts working, drawing lubricating oil from the oil tank and delivering it to the oil chamber. Then, the lubricating oil in the oil chamber is atomized and sprayed into a uniform oil mist onto the surfaces of the upper and lower felt rollers. The upper and lower felt rollers absorb the oil mist and are fully wetted. Subsequently, the aluminum material passes uniformly between the upper and lower felt rollers, which contact the aluminum surface and, through rolling friction, evenly coat the upper and lower surfaces of the aluminum material with lubricating oil, forming a continuous and fully covered isolation film. The thickness of this isolation film can be adjusted by controlling the oil volume using a regulating valve. During the lubricating oil spraying process, excess lubricating oil drips into the oil collection box due to gravity, effectively preventing lubricating oil spillage and environmental pollution. Simultaneously, the recovered oil collected in the oil collection box is transported to the oil tank for recycling. When the machine runs again, the hydraulic pump will draw lubricating oil from the oil tank and deliver it to the atomizing oil sprayer for a new round of oil injection, thus forming a closed loop.

[0008] The advantages of this solution are: (1) Compared to operator application, this solution breaks the technical bias of "efficiency and consistency". Through atomized oil spray, felt roller and regulating valve, this solution can not only achieve an efficient and continuous workflow, but also ensure the consistency and stability of each operation, and avoid quality fluctuations caused by human factors.

[0009] (2) The automatic coating method of this solution not only improves the utilization rate of lubricating oil, reduces environmental impact, and ensures the safety and cleanliness of operation, but also greatly shortens the preparation time and operation cycle, and improves the overall production efficiency.

[0010] (3) The dual function of “atomized oil spray + felt roller” in this solution ensures the consistency of the isolation film and avoids the isolation film being too thick or missing, thereby improving product quality.

[0011] (4) In this solution, the atomized oil spray is distributed in an array, so that the lubricating oil can evenly cover the surface of the aluminum material, avoiding the problem of excessively thick or missing isolation film in some areas.

[0012] (5) This solution can precisely adjust the amount of oil sprayed by each atomizing oil spray through the regulating valve, so that the thickness of the isolation film can be finely adjusted according to specific production needs, ensuring the best lubrication effect, and ensuring that the minimum amount of lubricating oil is used to achieve the best lubrication effect, reducing oil waste and saving costs.

[0013] (6) The overall structure of this solution is simple and the principle is clear. Its ingenuity lies in the fact that an atomized oil sprayer is installed at the discharge end of the existing leveling machine without affecting the normal operation of the equipment. At the same time, felt rollers (i.e., upper felt rollers and lower felt rollers) are installed on one side of the atomized oil sprayer. The felt rollers can not only assist in applying oil during the aluminum material conveying process and improve the lubrication effect, but also enhance the flatness of the aluminum material conveying to a certain extent, thereby improving the surface quality and processing efficiency of the aluminum material.

[0014] Preferably, as an improvement, the tilt angle α between the oil receiving box and the fixing frame is 94-96°.

[0015] Beneficial effects: The tilt angle α design allows the oil collection box to collect excess lubricating oil dripping from the felt roller or aluminum surface more efficiently. Under gravity, the lubricating oil naturally flows to the lowest point of the collection box, preventing it from stagnating or overflowing, thus improving recovery efficiency. It also facilitates the return of recovered oil to the oil tank.

[0016] Preferably, as an improvement, the inner side of the fixing frame is provided with a slot for engaging the upper felt roller, and the two ends of the upper felt roller are provided with bearings and engaged in the slot; a spring fixing rod for positioning the upper felt roller is provided between the upper felt roller and the bottom of the oil cavity; the two ends of the lower felt roller are connected to the fixing frame through bearings.

[0017] Beneficial Effects: The design of the slot and spring-loaded retaining rod facilitates height adjustment of the upper felt roller. The elasticity of the spring-loaded retaining rod allows the upper felt roller to automatically adjust its height and pressure according to the thickness of the aluminum material, thereby precisely controlling the gap between the upper and lower felt rollers. This adaptive adjustment function ensures good lubrication of the aluminum material under different thicknesses. Furthermore, the spring-loaded retaining rod also serves to fix the upper felt roller, helping to accurately position its height and pressure, ensuring it remains in the optimal position during operation. The bearing assists in rotation, allowing the upper and lower felt rollers to remain stable during rotation, reducing vibrations caused by friction or imbalance, and ensuring the stability and reliability of the device.

[0018] Preferably, as an improvement, the longitudinal length of the slot is 20mm-30mm, and the telescopic length of the spring fixing rod is 30mm-50mm.

[0019] Beneficial effects: The longitudinal length of the slot is designed to be 20mm-30mm, providing sufficient space to support the upper felt roller's vertical movement within a certain range. This allows the device to adapt to the processing needs of aluminum materials of different thicknesses, enhancing its flexibility and versatility. The telescopic length of the spring fixing rod is 30mm-50mm, stabilizing the adjustable range of the upper felt roller and ensuring that it is always in the optimal position during operation. Furthermore, the elastic telescopic function of the spring allows for dynamic adjustment of the roller position, ensuring more precise lubrication of materials of different thicknesses.

[0020] Preferably, as an improvement, the number of atomizing oil sprays is 20-40.

[0021] Beneficial effects: The atomized oil spray quantity design can be adjusted according to the aluminum material of different widths to ensure that the lubricating oil can evenly cover the entire surface of the aluminum material, avoiding the phenomenon of excessively thick or missing oil film in some areas.

[0022] Preferably, as an improvement, the fixing bracket is located in the middle of the oil receiving box, and the oil receiving box has a length of 500mm-1000mm, a width of 80mm-200mm, and a depth of 40mm-60mm.

[0023] Beneficial effects: The mounting bracket is located in the center of the oil collection box. This design allows excess lubricating oil dripping from the felt roller or aluminum surface to flow more concentratedly to the central area of ​​the collection box. It also fully considers the range of lubricating oil dripping, ensuring that all dripping lubricating oil is effectively collected, preventing leakage into the external environment, reducing the risk of pollution, and preventing lubricating oil dispersion and loss, thus improving recovery efficiency. The dimensions (length, width, depth) of the oil collection box ensure sufficient volume to hold the recovered lubricating oil while facilitating compatibility with the overall equipment structure. It can flexibly adapt to the processing needs of different specifications of aluminum materials, ensuring effective collection of lubricating oil whether processing narrow or wide strips.

[0024] Preferably, as an improvement, an oil inlet is provided at the connection between the fixing frame and the oil cavity, and the oil cavity is connected to the oil tank through the oil inlet.

[0025] Beneficial effects: The design of the oil inlet ensures that the oil chamber can continuously obtain lubricating oil from the oil tank, ensuring that the operation will not be interrupted due to insufficient lubricating oil during the lubrication process.

[0026] Preferably, as an improvement, the bottom of the oil receiving box is provided with an oil drain port, the oil drain port is located at the front end of the oil receiving box, and a ball valve connector is provided inside the oil drain port.

[0027] Beneficial effects: The oil drain port is located at the bottom front of the oil collection box, ensuring that the lubricating oil can flow smoothly to the lowest point and be discharged centrally, avoiding lubricating oil residue or stagnation inside the oil collection box, and improving the lubricating oil recovery efficiency. The ball valve connector is easy to operate, providing a fast and reliable on / off function, easily controlling the lubricating oil discharge process, and has good sealing performance, reducing the risk of leakage.

[0028] Preferably, as an improvement, the lubrication hydraulic system further includes a filter and a solenoid valve. One side of the filter is provided with an oil inlet port, the other side of the filter is connected to one side of the hydraulic pump, the other side of the hydraulic pump is connected to one side of the solenoid valve, and the other side of the solenoid valve is provided with an oil outlet port.

[0029] Beneficial effects: The filter is used to effectively remove impurities, particulate matter and other contaminants from the lubricating oil; the solenoid valve is used to control the flow rate and direction of the lubricating oil.

[0030] Preferably, as an improvement, both the upper felt roller and the lower felt roller are made of wool felt.

[0031] Beneficial effects: Wool felt has excellent oil absorption capacity, which can effectively absorb and retain lubricating oil. At the same time, wool felt is soft and has a certain degree of elasticity, which can effectively reduce wear and friction between it and aluminum.

[0032] The beneficial effects of this solution are: (1) In this solution, a closed loop is formed between the oiling device and the lubrication hydraulic system. The oiling device automatically sprays oil to form an isolation film on the aluminum material. The excess lubricating oil is collected by the oil collection box and reintroduced into the oil tank for reuse, reducing resource waste and lowering the risk of environmental pollution.

[0033] (2) Atomized oil spray + felt roller: ensures that the lubricating oil can evenly cover the aluminum surface, forming a continuous and fully covered isolation film, improving product surface quality and processing efficiency. Attached Figure Description

[0043] The following detailed description illustrates the specific implementation method:

[0044] The reference numerals in the accompanying drawings of the instruction manual include: leveling machine 1, oiling device 2, oil chamber 201, oil inlet 202, atomizing oil spray 203, regulating valve 204, upper felt roller 205, lower felt roller 206, oil receiving box 207, oil outlet 208, spring fixing rod 209, slot 210, fixing bracket 211, lubrication hydraulic system 3, oil tank 301, hydraulic pump 302, filter 303, oil inlet pipe interface 304, oil outlet pipe interface 305, solenoid valve 306, mounting bracket 4, oil outlet pipe 5, and oil inlet pipe 6.

[0045] Example 1:

[0046] The implementation examples are basically as follows Figure 1 The diagram shows an automatic oiling and lubrication device based on intelligent control, comprising an oiling device 2 and a lubrication hydraulic system 3 connected to the oiling device 2. During the production of aluminum materials using progressive dies, the automatic oiling and lubrication device is fixed to the discharge end of the leveling machine 1 via a mounting bracket 4. It is used to pre-lubricate the surface of the aluminum material about to undergo stamping, forming a uniform isolation film to effectively reduce friction and wear problems that may occur during subsequent processing, thereby improving the quality of the aluminum material. In this embodiment, the leveling machine 1 (also called a leveling machine or screed) is an industrial device used to correct unevenness on the surface of metal sheets, coils, or other materials. Its main function is to eliminate internal stress in the material through mechanical force, achieving a flat and smooth state. A progressive die (also called a continuous die) is a high-efficiency stamping die that can complete multiple processes (such as punching, bending, forming, cutting, etc.) within a single stroke.

[0047] like Figure 2 , Figure 3As shown. The oiling device 2 includes several fixed frames 211, with an oil chamber 201, an upper felt roller 205, and a lower felt roller 206 installed between adjacent fixed frames 211. Specifically, two fixed frames 211 form a support frame, and the oil chamber 201, upper felt roller 205, and lower felt roller 206 are installed sequentially from top to bottom between adjacent fixed frames 211. The oil chamber 201 is fixedly connected to the fixed frame 211, and an oil inlet 202 is provided at the connection between the oil chamber 201 and the fixed frame 211. The oil inlet 202 is a double-ended oil inlet design (i.e., oil can be supplied from both ends simultaneously) to provide a continuous oil volume to the oil chamber 201, ensuring sufficient and uniform lubrication supply, thereby maintaining a stable lubrication effect. Several atomizing oil sprays 203 and a regulating valve 204 are arranged on the oil chamber 201. The atomizing oil sprays 203 are located at the bottom of the oil chamber 201 and arranged in an array to ensure that the lubricating oil evenly covers the entire working area of ​​the aluminum material. The regulating valve 204 is located at the top of the oil chamber 201 and is used to regulate the oil volume of the atomized oil spray 203, ensuring optimal lubrication while reducing oil waste and saving costs. In this embodiment, the number of atomized oil sprays 203 is 20-40, which can be dynamically adjusted according to the aluminum material of different widths to ensure that the lubricating oil can evenly cover the entire surface of the aluminum material, avoiding the phenomenon of excessively thick or missing oil films in some areas. The number of atomized oil sprays 203 corresponds one-to-one with the number of regulating valves 204, and each atomized oil spray 203 is equipped with a regulating valve 204 for corresponding adjustment.

[0048] The upper felt roller 205 is located directly below the atomizing oil spray 203 to effectively absorb the lubricating oil released by the atomizing oil spray 203. Bearings are installed at both ends of the upper felt roller 205 to assist its free rotation, ensuring stability during rotation and reducing friction and wear between the upper felt roller 205 and the fixed frame 211, thus ensuring the stability and reliability of the device operation. The ends of the upper felt roller 205 engage with the slots 210 inside the fixed frame 211. Spring fixing rods 209 are installed between the upper felt roller 205 and the bottom of the oil chamber 201. It should be noted that the spring fixing rods 209 are located at both ends of the upper felt roller 205, and not directly mounted on the body of the upper felt roller 205. The elasticity of the spring fixing rod 209 allows the upper felt roller 205 to automatically adjust its height and pressure according to the thickness of the aluminum material, thereby precisely controlling the gap between the upper felt roller 205 and the lower felt roller 206 to accommodate aluminum materials of different thicknesses. In addition, the spring fixing rod 209 has a fixing function, helping to accurately position the height and pressure of the upper felt roller 205 and ensuring stable contact between it and the surface of the aluminum material.

[0049] The lower felt roller 206 is located below the upper felt roller 205, and bearings are provided at both ends to assist the free rotation of the lower felt roller 206, ensuring smooth rotation and reducing friction and wear between the lower felt roller 206 and the fixed frame 211, thus ensuring the stability and reliability of the device operation. The ends of the lower felt roller 206 are fixedly connected to the fixed frame 211 by bolt threads, ensuring a secure installation. In this embodiment, both the upper felt roller 205 and the lower felt roller 206 are made of wool felt. Wool felt has excellent oil absorption capacity, effectively absorbing and retaining lubricating oil. Simultaneously, wool felt is soft and has a certain degree of elasticity, effectively reducing wear and friction with the aluminum material and ensuring the flatness of the aluminum material.

[0050] In this embodiment, the longitudinal length of the slot 210 is 20mm-30mm, and the telescopic length of the spring fixing rod 209 is 30mm-50mm. The longitudinal length design of the slot 210 provides sufficient space to support the upper felt roller 205 to move up and down within a certain range, thus enabling the device to adapt to the processing needs of aluminum materials of different thicknesses, enhancing the flexibility and versatility of the device. The telescopic length of the spring fixing rod 209 stabilizes the adjustable range of the upper felt roller 205, ensuring that the upper felt roller 205 is always in the optimal position during operation. Furthermore, the elastic telescopic function of the spring allows for dynamic adjustment of the roller position, ensuring more precise lubrication treatment of materials of different thicknesses.

[0051] An oil collection box 207 for collecting lubricating oil is installed at an angle at the bottom of the mounting bracket 211. The mounting bracket 211 is located in the middle of both sides of the oil collection box 207, and the oil collection box 207 is located below the lower felt roller 206. The mounting bracket 211's central location in the oil collection box 207 allows excess lubricating oil dripping from the felt roller or aluminum surface to flow more concentratedly to the central area of ​​the oil collection box 207. This design also fully considers the range of lubricating oil dripping, ensuring that all dripping lubricating oil is effectively collected, preventing leakage into the external environment, reducing the risk of pollution, and preventing lubricating oil dispersion and loss, thus improving recovery efficiency. Figure 4 As shown, the tilt angle α between the oil collection box 207 and the fixing frame 211 is 94-96°. The design of the tilt angle α makes the oil collection box 207 tilt downward, so that the oil collection box 207 can collect excess lubricating oil dripping from the felt roller or aluminum surface more efficiently. At the same time, the lubricating oil will naturally flow to the lowest point of the oil collection box 207 under the action of gravity, avoiding the lubricating oil from being stuck in the oil collection box 207 or overflowing, thereby improving the recycling efficiency; and facilitating the return of the recycled oil to the oil tank 301.

[0052] like Figure 5 As shown ( Figure 5(The wavy line in the image indicates the remaining portion not shown). The oil collection box 207 has a length of 500mm-1000mm, a width of 80mm-200mm, and a depth of 40mm-60mm. This design ensures sufficient volume to hold the recovered lubricating oil while also facilitating compatibility with the overall equipment structure. It can flexibly adapt to the processing needs of different specifications of aluminum materials, ensuring effective collection of lubricating oil whether processing narrow or wide materials.

[0053] An oil drain port 208 is installed at the bottom of the oil collection box 207. Located at the front end of the oil collection box 207, the drain port 208's position design allows lubricating oil to flow smoothly to the lowest point and be discharged centrally, effectively preventing lubricating oil residue or stagnation inside the oil collection box 207 and improving lubricating oil recovery efficiency. Furthermore, a ball valve connector is installed inside the drain port 208, simplifying the operation process, providing a quick and reliable on / off function, easily controlling the lubricating oil discharge process, and ensuring good sealing to reduce the risk of leakage.

[0054] The lubrication hydraulic system 3 is controlled by a PLC (Programmable Logic Controller) / control unit to recover and transport lubricating oil, realizing the linkage control of the entire automatic oiling and lubrication device with the leveling machine 1.

[0055] Among them, such as Figure 6 , Figure 7 As shown, the lubrication hydraulic system 3 includes an oil tank 301 for storing lubricating oil. A hydraulic pump 302, a filter 303, and a solenoid valve 306 are mounted above the oil tank 301. One side of the filter 303 is connected to an oil inlet port 304, and the other side of the filter 303 is connected to one side of the hydraulic pump 302 via a pipe. The other side of the hydraulic pump 302 is connected to one side of the solenoid valve 306 via a pipe, and the other side of the solenoid valve 306 is connected to an oil outlet port 305. The hydraulic pump 302 provides power to draw lubricating oil from the oil tank 301; the solenoid valve 306 controls the flow rate and direction of the lubricating oil; and the filter 303 filters the recovered oil, effectively removing impurities, particulate matter, and other contaminants.

[0056] The specific implementation process is as follows:

[0057] Before processing: such as Figure 8As shown, the oiling device 2 is installed: the oiling device 2 is fixed to the feed end of the leveling machine 1 by the mounting bracket 4, ensuring its position is aligned with the aluminum material conveying path, and adjusting the height and width of the mounting bracket 4 so that the oil spraying area of ​​the oiling device 2 covers the entire width of the aluminum material surface. Next, the lubrication hydraulic system 3 is connected: the oil inlet 202 of the oiling device 2 is connected to the oil outlet interface 305 in the lubrication hydraulic system 3 through the oil outlet pipe 5 to provide lubricating oil to the oiling device 2; the oil inlet interface 304 in the lubrication hydraulic system 3 is connected to the oil drain port 208 at the bottom of the oil receiving box 207 through the oil inlet pipe 6 to recover excess lubricating oil. A closed-loop circuit is formed between the oiling device 2 and the lubrication hydraulic system 3.

[0058] Processing procedure: such as Figure 9 As shown, when the automatic oiling and lubrication device is started, the hydraulic pump 302 begins to work, drawing lubricating oil from the oil tank 301. The solenoid valve 306 opens, and the lubricating oil is delivered from the oil outlet pipe 5 to the oil chamber 201 of the oiling device 2. Next, the lubricating oil in the oil chamber 201 is converted into a uniform oil mist by the atomizing oil spray 203, spraying it onto the surfaces of the upper felt roller 205 and the lower felt roller 206. The upper and lower felt rollers 205 and 206 absorb the oil mist and are fully wetted, forming a stable oil film layer. Afterwards, the leveling machine 1 is started, and the aluminum material is fed into the leveling machine 1 from the feed end, passing uniformly through the gap between the upper and lower felt rollers 205 and 206. The upper and lower felt rollers 205 and 206 contact the upper and lower surfaces of the aluminum material, and through rolling friction, the lubricating oil is evenly applied to the upper and lower surfaces of the aluminum material, forming a continuous, fully covered isolation film. The thickness of the insulating oil film can be controlled by adjusting the oil volume of the regulating valve 204 or the pressure of the felt roller. Simultaneously, when aluminum materials of different thicknesses pass through the gap between the upper felt roller 205 and the lower felt roller 206, the change in aluminum thickness will push the upper felt roller 205 upwards, causing the slot 210 and the spring fixing rod 209 to displace accordingly, moving the upper felt roller 205 to a new equilibrium position, thus accommodating the processing of aluminum materials of different thicknesses.

[0059] During the lubricating oil spraying process, excess lubricating oil drips into the oil collection box 207 at the bottom of the device due to gravity, preventing oil spillage and environmental pollution. The recovered oil in the oil collection box 207 flows to the lowest point and into the oil inlet pipe 6 through the oil outlet 208. The recovered oil is first filtered by the filter 303 to remove impurities such as metal shavings and dust, ensuring the cleanliness of the recovered oil. After filtration, the lubricating oil is transported to the oil tank 301 and mixed with new oil / oil mixture (fresh lubricating oil is added as needed to maintain the oil level). When the device is run again, the hydraulic pump 302 draws lubricating oil from the oil tank 301 and delivers it to the atomizing oil sprayer 203 through the oil outlet pipe 5, thus forming a closed-loop cycle.

[0060] The overall structure of this solution is simple and the principle is clear. Its ingenuity lies in the installation of an atomized oil sprayer at the discharge end of the existing leveling machine, which does not affect the normal operation of the equipment. At the same time, felt rollers (i.e., upper and lower felt rollers) are installed on one side of the atomized oil sprayer. The felt rollers can not only assist in applying oil during the aluminum material conveying process and improve the lubrication effect, but also enhance the flatness of the aluminum material conveying to a certain extent, thereby improving the surface quality and processing efficiency of the aluminum material.

[0061] In existing technologies, the product qualification rate using operator-applied methods is 50%. This solution breaks the technological bias of prioritizing "efficiency over consistency." Through atomized oil spray 203, felt rollers, and regulating valve 204, this solution not only achieves an efficient and continuous workflow but also ensures consistency and stability in each operation, avoiding quality fluctuations caused by human factors. Production statistics show that the qualification rate after implementing this solution is over 95%. Specifically, this solution utilizes the dual action of "atomized oil spray 203 + felt roller" to ensure the consistency of the isolation membrane, preventing it from being too thick or missing, thereby improving product quality. The regulating valve 204 allows for precise adjustment of the oil volume of each atomized oil spray 203, enabling fine-tuning of the isolation membrane thickness according to specific production needs. This ensures optimal lubrication and minimizes oil waste, achieving the best lubrication effect. The oil collection box 207's structural design efficiently collects excess lubricating oil dripping from the felt roller or aluminum surface. Furthermore, the collected lubricating oil naturally flows to the lowest point of the collection box 207 under gravity, preventing oil stagnation or overflow, thus improving recovery efficiency.
