By soaking the blade in a specific oil, the purposes of rust prevention, lubrication, protecting the blade material, and extending the service life can be achieved. The existing oil soaking work specifically includes the following steps: First, cleaning, using warm water and a neutral cleaner to clean the blade, removing oil stains and impurities, and ensuring that there is no moisture on the surface after cleaning; Second, oil soaking, completely soaking the blade in the oil to ensure that both the blade edge and the blade body are covered by the oil, and the soaking time depends on the blade material and usage frequency; Third, draining, draining the excess oil on the blade surface to avoid oil stains contaminating other items.

[0003] It can be seen that the existing oil soaking technology not only requires multiple working steps, but also the working steps such as cleaning, oil soaking, and draining are carried out separately. When performing different working steps, the blade needs to be moved frequently, resulting in too low efficiency and high working intensity, which needs to be improved. Summary of the Invention

[0009] Furthermore, a mounting frame in a fin structure is fixedly connected to the bottom plate, and the electric push rod is connected to the bottom plate through the mounting frame, and the mounting frame is connected to the air duct in a wrapping manner.

[0010] Furthermore, the inner bottom surface of the sector-shaped empty bin is provided with two symmetrically distributed interception bars, and the two interception bars are respectively located below the left edge and the right edge of the oil bubble bin.

[0011] Furthermore, the oil bubble tank and the electric push rod are detachably connected to a cover plate.

[0013] 2. Compared with the existing oil soaking technology, the present invention utilizes heated oil, the oil film is uniform and dense, deeply penetrated, and has excellent protective effect.

[0014] 3.

Detailed implementation manners

[0018] The following is only a preferred embodiment of the present invention and does not limit the protection scope of the present invention accordingly.

[0019] Embodiment 1 An automatic oil soaking device, as Figures 1-9 shown, includes a bottom plate 1 and an oil soaking tank 2; the bottom plate 1 is provided with the oil soaking tank 2; It further includes an electric push rod 3, a cross bracket 4, a driving motor 5, a connecting cylinder 6, a bearing frame 7 and a placement frame 8; the oil soaking tank 2 is divided into four areas: a loading and unloading bin 2001, a cleaning cavity 2002, an oil soaking bin 2003 and a draining cavity 2004; the bottom plate 1 is provided with the electric push rod 3; the telescopic part of the electric push rod 3 is fixedly connected with the cross bracket 4; the cross bracket 4 is installed with the driving motor 5; the output shaft of the driving motor 5 is fixedly connected with the connecting cylinder 6; the connecting cylinder 6 is fixedly connected with four bearing frames 7 distributed in a circular array, and the four bearing frames 7 correspond to the four areas of the oil soaking tank 2 one by one; each bearing frame 7 is placed with a placement frame 8 for loading blades.

[0020] An oil heating device for heating the oil in the oil soaking chamber 2003 is provided in the oil soaking chamber 2003.

[0021] The specific working process of the present invention is as follows: First, inject an appropriate amount of oil into the oil soaking chamber 2003, and then prepare several placement frames 8, and place an appropriate amount of cleaned blades in each placement frame 8 for subsequent oil soaking work; then, place the placement frame 8 containing the cleaned blades in the bearing frame 7 in the loading and unloading chamber 2001. Then, control the telescopic part of the electric push rod 3 to drive the cross bracket 4, the drive motor 5, the connecting cylinder 6, the bearing frame 7 and the placement frame 8 containing the cleaned blades to move upward together, so that the bearing frame 7 and the placement frame 8 containing the cleaned blades move upward away from the loading and unloading chamber 2001. Then, control the output shaft of the drive motor 5 to drive the connecting cylinder 6, the bearing frame 7 and the placement frame 8 containing the cleaned blades to rotate 90 degrees clockwise from a top-down perspective, so that the placement frame 8 containing the cleaned blades rotates from above the loading and unloading chamber 2001 to above the cleaning cavity 2002. Then, control the telescopic part of the electric push rod 3 to drive the cross bracket 4, the drive motor 5, the connecting cylinder 6, the bearing frame 7 and the placement frame 8 containing the cleaned blades to move downward together, so that the bearing frame 7 and the placement frame 8 containing the cleaned blades move downward into the cleaning cavity 2002. At this time, control the external air drying device to perform air drying work on the cleaned blades in the placement frame 8 in the cleaning cavity 2002 from bottom to top, so as to eliminate the water droplets remaining on the blade surface and ensure that the subsequent oil film adheres more evenly; Then, according to the above transfer steps, transfer the placement frame 8 containing the air-dried blades from the cleaning cavity 2002 to the oil soaking chamber 2003 for blade oil soaking work, so that an oil film is formed on the blade surface, achieving the purposes of rust prevention, lubrication, protecting the blade material and extending the service life; Then, according to the above transfer steps, transfer the placement frame 8 containing the oil-soaked blades from the oil soaking chamber 2003 to the draining cavity 2004, and control the external air drying device to perform draining work on the oil-soaked blades in the placement frame 8 in the draining cavity 2004 from bottom to top to accelerate the volatilization of the oil and avoid oil contamination of other items; Then, according to the above transfer steps, transfer the placement frame 8 containing the drained blades from the draining cavity 2004 to the loading and unloading chamber 2001 for blade removal work, completing an overall process of blade oil soaking. Since the air drying, oil soaking and draining work all require a certain amount of time, during this period, there is enough time to take out the placement frame 8 containing the drained blades from the loading and unloading chamber 2001 and put in a placement frame 8 containing the cleaned blades; When the fourth placement frame 8 in the same batch is placed into the loading and unloading bin 2001, the loading and unloading bin 2001, the cleaning cavity 2002, the oil soaking bin 2003, and the draining cavity 2004 start to work synchronously. The operator only needs to be responsible for putting in and taking out the placement frame 8. In this way, the integration of cleaning, oil soaking, and draining is realized. Moreover, the overall structure of the present invention is compact and occupies little space, achieving the purpose of cost reduction and efficiency improvement, and solving the problems of the existing oil soaking technology. Not only does it require multiple working steps to be completed, but also the working steps such as cleaning, oil soaking, and draining are carried out separately. When performing different working steps, the blade needs to move frequently, resulting in too low efficiency and high working intensity.

[0022] During the above oil soaking process, the oil liquid in the oil soaking bin 2003 is heated by the oil liquid heating device. Using high-temperature oil liquid for oil soaking work has the following advantages compared with using low-temperature or normal-temperature oil liquid: 1. Uniformity of oil film adhesion: Low temperature (close to room temperature): The viscosity of the oil liquid is relatively high and the fluidity is poor, resulting in uneven distribution of the oil film on the blade surface, and local thick or thin areas may be formed.

[0023] High temperature (80 - 120 °C): The viscosity of the oil liquid decreases, the fluidity increases, and the oil film is more likely to evenly cover the blade surface, reducing bubbles or uncovered areas.

[0024] 2. Oil liquid permeability: Low temperature: The permeability is poor, and only an oil film is formed on the surface, with limited protection effect.

[0025] High temperature: The movement of oil liquid molecules accelerates, and it is more likely to penetrate into the micropores or cracks of the blade to form a deep protection layer.

[0026] 3. Chemical reaction rate: Low temperature: The reaction rate decreases, and the formation of the protection layer is slow.

[0027] High temperature: If the oil liquid contains additives (such as rust inhibitors, antioxidants), high temperature can accelerate its chemical reaction with the blade surface to form a more stable protection layer.

[0028] In summary, compared with the existing oil soaking technology, the present invention uses heated oil liquid, with a uniform and dense oil film, deep penetration, and excellent protection effect.

[0029] Embodiment 2 On the basis of the above Embodiment 1, as Figures 6-9As shown in the figure, it further includes a sector empty bin 10, an air duct 11 and a fan 12; the bottom plate 1 is bolted with the sector empty bin 10, and the oil soaking tank 2 is connected to the bottom plate 1 through the sector empty bin 10, and the sector empty bin 10 cooperates with the oil soaking tank 2; the bottom plate 1 and the sector empty bin 10 are jointly fixedly connected with an air duct 11; the air duct 11 is provided with an air outlet 11001, and the air duct 11 is communicated with the inside of the sector empty bin 10 through the air outlet 11001; at least two fans 12 are installed on the air duct 11; each end of the sector empty bin 10 is provided with a drain groove 10001, and the water droplets and oil liquid dripping from the cleaning cavity 2002 and the draining cavity 2004 onto the sector empty bin 10 are discharged through the drain groove 10001.

[0030] The oil soaking tank 2 and the sector empty bin 10 are jointly provided with a number of arc-shaped fins 13, and the arc-shaped fins 13 are located below the oil soaking bin 2003.

[0031] The specific working process of the present invention is as follows: After the blade is soaked in hot oil, if it is directly in contact with the low-temperature or normal-temperature air flow blown out by the external air-drying device, the following problems will occur: First, when the high-temperature blade suddenly contacts the low-temperature air, the surface shrinks rapidly, while the inside still remains at a high temperature, resulting in thermal stress concentration, and the blade cracks or deforms due to thermal stress.

[0032] Second, when the temperature difference is too large, the oil film may rupture due to rapid surface cooling, losing its protective effect. Moreover, if the environmental humidity is high, water vapor may condense on the surface of the oil film, accelerating rusting.

[0033] Therefore, after the blade is soaked in hot oil, control the fan 12 to blow air through the air duct 11 and the air outlet 11001 into the sector empty bin 10, so that the air flow first flows through the area below the oil soaking bin 2003, makes the air flow receive the heat emitted by the oil soaking bin 2003, raises the temperature of the air flow, and then flows towards the two ends of the sector empty bin 10. Among them, the air flow flowing to the right, after being blocked and intercepted by the right end of the sector empty bin 10, then passes upward through the draining cavity 2004 from the right end of the sector empty bin 10, so as to air-dry the oil-soaked blade in the draining cavity 2004 through the heated air flow, promote the volatilization of the oil liquid, and replace the external air-drying device, avoiding the problems that the blade cracks or deforms when directly contacting the low-temperature or normal-temperature air flow blown out by the external air-drying device after being soaked in hot oil, and when the temperature difference is too large, the oil film may rupture due to rapid surface cooling and lose its protective effect.

[0034] Meanwhile, among them, the airflow flowing to the left end, after being blocked and intercepted by the left end of the fan-shaped empty bin 10, then passes upward through the cleaning cavity 2002 from the left end of the fan-shaped empty bin 10, so as to air-dry the cleaned blades in the cleaning cavity 2002 through the airflow after the temperature rises, thereby replacing the peripheral air-drying equipment, and using the airflow with a relatively high temperature to accelerate the evaporation time of the water droplets on the blade surface, so as to enhance the drying effect and improve the drying efficiency.

[0035] It should be noted that by utilizing the heat emitted by the oil soaking bin 2003, the present invention not only saves the heat source required for heating the airflow, but also achieves the purpose of waste heat utilization, further reducing the production and processing cost.

[0036] Moreover, in the above process, through the arc-shaped fins 13, the heat of the oil soaking bin 2003 can be dissipated into the fan-shaped empty bin 10 to the greatest extent, ensuring that the airflow flowing in the fan-shaped empty bin 10 has sufficient temperature and reducing the problems caused by the temperature difference between the airflow and the blade.

[0037] Meanwhile, the oil liquid in the oil soaking bin 2003 is continuously heated by the oil liquid heating device to prevent the temperature of the oil liquid in the oil soaking bin 2003 from being insufficient.

[0038] Embodiment 3 On the basis of the above Embodiment 2, as Figures 6-9 shown, the bottom plate 1 is bolted with a mounting frame 20 in a fin structure, and the electric push rod 3 is connected to the bottom plate 1 through the mounting frame 20, and the mounting frame 20 is connected to the air duct 11 in a wrapping manner.

[0039] Two intercepting strips 30 are symmetrically arranged on the inner bottom surface of the fan-shaped empty bin 10, and the two intercepting strips 30 are respectively below the left edge and the right edge of the oil soaking bin 2003, and the intercepting strips 30 are used to separate the water droplets and oil liquid dripping from the cleaning cavity 2002 and the draining cavity 2004 onto the fan-shaped empty bin 10, so as to prevent the water droplets and oil liquid from mixing together, resulting in the inability to recycle the oil liquid or increasing the recycling difficulty.

[0040] The oil soaking tank 2 and the electric push rod 3 are jointly detachably connected with a cover plate 40 to prevent oil and water from entering the area of the electric push rod 3 and affecting the normal operation of the electric push rod 3.

[0041] The working process of the present invention is as follows: During the above working process, the electric push rod 3 itself will emit a certain amount of heat, and since the electric push rod 3 is close to the oil soaking bin 2003, the fixing part of the electric push rod 3 will also be affected by the heat dissipated from the oil soaking bin 2003, resulting in a reduction in the service life of the electric push rod 3; Therefore, in the above process, the electric push rod 3 is cooled by the mounting frame 20 in the form of a fin structure, and the heat dissipated by the electric push rod 3 is conducted to the air duct 11 through the mounting frame 20 in the form of a fin structure. The heat conducted by the mounting frame 20 to the air duct 11 is carried away by the air flow flowing through the air duct 11. In this way, while cooling the electric push rod 3, the dissipated heat is also conducted into the air flow flowing through the air duct 11, so that the air flow flowing through the air duct 11 contains a certain amount of heat before entering the fan-shaped empty bin 10. In this way, the increase in the air flow temperature further reduces the temperature difference between the air flow and the blade, avoiding problems such as cracks or deformation of the blade caused by too large a temperature difference and the oil film breaking and losing the protection effect.

[0042] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
