Description

Technical Field

[0001] This utility model relates to a hot air knife degreasing mechanism for aluminum foil rolling mill winding. Background Technology

[0002] Aluminum foil rolling mills are key pieces of equipment in the aluminum foil production process. Rolling oil is used during rolling to reduce friction, cool the rolls, and improve product quality. However, a large amount of rolling oil remains on the surface of the rolled aluminum foil, which can affect the processing quality of subsequent steps and the performance of the final product. Therefore, effective degreasing treatment of the aluminum foil surface before winding in the rolling mill is crucial.

[0003] Existing aluminum foil rolling mill degreasing devices still have the following problems: traditional blowing devices have simple structures and limited degreasing effects, making it difficult to completely remove rolling oil from the surface of aluminum foil; most degreasing devices lack an effective oil collection system, resulting in splashing oil that pollutes the environment or is wasted.

[0004] Therefore, there is an urgent need for a hot air knife degreasing mechanism for aluminum foil rolling mills that has a good degreasing effect and can effectively collect waste oil. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a hot air knife degreasing mechanism for aluminum foil rolling mill winding. By cooperating with the hot air knife and the fan, and simultaneously adding an oil storage structure, the degreasing effect is increased, and waste oil is effectively collected. This purpose of this utility model is achieved as follows:

[0006] This utility model proposes a hot air knife degreasing mechanism for aluminum foil rolling mill winding, comprising a main body, on which unwinding rollers and winding rollers are symmetrically mounted on both sides. A hot air knife is arranged between the unwinding rollers and winding rollers. The hot air knife is fixed to the main body by a mounting rod. The hot air knife is V-shaped with its tip facing the unwinding roller. The relative angle between the hot air knife and the upper surface of the main body is 30-40 degrees. Several fans are mounted on the hot air knife and arranged in a strip on the hot air knife. Two oil storage tanks are opened on both sides of the main body. The fans are used to blow the oil on the hot air knife into the oil storage tanks.

[0007] Furthermore, it also includes a control device located on one side of the main body.

[0008] Furthermore, a detection device is arranged between the unwinding roller and the hot air knife, and the detection device is fixed to the main body by a mounting rod.

[0009] Furthermore, all the fans are electrically connected to a control device for controlling the power of the fans.

[0010] Furthermore, the hot air knife includes blades on both sides, with an angle of 120 degrees between the blades.

[0011] Furthermore, the end of the blade is positioned on the upper side of the oil reservoir.

[0012] Furthermore, an oil outlet is installed on one side of the oil storage tank.

[0013] Furthermore, the oil storage tank is inclined downward at 30-40 degrees toward the winding roller.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by setting a V-shaped hot air knife at a specific angle during the aluminum foil rolling mill winding process, and installing a strip-shaped fan on the hot air knife, the oil stains on the surface of the aluminum foil can be effectively removed;

[0015] The design of the hot air knife with a relative angle of 30-40 degrees to the upper surface of the main body allows the hot air to be blown onto the aluminum foil surface at the optimal angle, improving the oil removal efficiency and collecting the oil in the oil storage tank for recycling, thus reducing environmental pollution.

[0019] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0020] Please refer to Figure 1-2 A hot air knife 5 degreasing mechanism for aluminum foil rolling mill winding includes a body 1. Unwinding rollers 9 and winding rollers 7 are symmetrically installed on both sides of the body 1. A hot air knife 5 is arranged between the unwinding rollers 9 and winding rollers 7. The hot air knife 5 is fixed to the body by a mounting rod. The hot air knife 5 is V-shaped with its tip facing the unwinding roller 9. The relative angle between the hot air knife 5 and the upper surface of the body is 30-40 degrees. Several fans 4 are installed on the hot air knife 5. The fans 4 are arranged in a strip on the hot air knife 5. Two oil storage tanks 3 are opened on both sides of the body. The fans 4 are used to blow the oil on the hot air knife 5 into the oil storage tanks 3.

[0021] In this embodiment, the hot air knife 5 degreasing mechanism for aluminum foil rolling mill serves as the supporting foundation for the entire device, ensuring the stability of the entire degreasing mechanism. The hot air knife 5 is arranged between the unwinding roller 9 and the winding roller 7, and is firmly fixed to the main body by a mounting rod. The mounting rod is designed to be adjustable up and down, making it easy to adjust the position of the hot air knife 5 to adapt to the degreasing needs of aluminum foil of different specifications. The hot air knife 5 has a V-shaped structure with the tip facing the unwinding roller 9. This design allows the aluminum foil to fully contact the aluminum foil surface when passing through the hot air knife 5, and to transport waste oil to both sides, improving the degreasing efficiency. The relative angle between the hot air knife 5 and the upper surface of the main body is 35 degrees. This angle design allows the hot air to blow onto the aluminum foil surface at the optimal angle, which can effectively remove oil stains without damaging the aluminum foil.

[0022] Understandably, multiple fans 4 are installed on the hot air knife 5. These fans 4 are arranged in a strip on the hot air knife 5 to form a continuous hot air zone. The fans 4 adopt a high-efficiency and energy-saving design, which can generate a stable hot air flow. The temperature can be adjusted according to the aluminum foil material and the oil stains. The number and arrangement of the fans 4 are determined according to the length of the hot air knife 5 and the width of the aluminum foil to ensure that the entire width of the aluminum foil can be treated with uniform hot air.

[0023] Understandably, two oil storage tanks 3 are opened on both sides of the main body to collect the oil stains blown off the surface of the aluminum foil. The design of the oil storage tank 3 takes into account the fluidity and collection efficiency of the oil stains. It adopts a smooth inner wall to facilitate the flow of oil stains and their centralized collection. The hot air generated by the blower 4 can not only heat the oil stains on the surface of the aluminum foil and reduce their viscosity, but also blow the oil stains toward the oil storage tank 3 to achieve effective collection and treatment of oil stains.

[0024] Understandably, the hot air knife 5 oil removal mechanism in this embodiment also includes a control device 8. The control device 8 is located on one side of the main body. The control device 8 adopts a microcomputer control system and is equipped with a touch screen operation interface, which is simple and intuitive to operate. The main function of the control device 8 is to control the operating status of the entire oil removal mechanism, including the start and stop of the fan 4, temperature adjustment, wind speed control, etc. The control device 8 also has fault diagnosis and alarm functions, which can promptly remind the operator to handle when the system malfunctions.

[0025] Understandably, a detection device 2 is also arranged between the unwinding roller 9 and the hot air knife 5. The detection device 2 is fixed to the main body by a mounting rod. The detection device 2 is mainly used to monitor the oil stains on the surface of the aluminum foil. It adopts a high-precision photoelectric sensor, which can detect the distribution and thickness of oil stains on the surface of the aluminum foil in real time. The detection device 2 is connected to the control device 8 and transmits the detection data to the control device 8. The control device 8 automatically adjusts the power of the fan 4 and the hot air temperature based on these data to achieve intelligent oil removal.

[0026] Understandably, all fans 4 are electrically connected to the control device 8 to control the power of the fans 4. The control device 8 can automatically adjust the power of the fans 4 according to the thickness, width, speed and oil stains of the aluminum foil, to ensure the oil removal effect while avoiding energy waste. The power adjustment range of the fans 4 is wide, which can meet the oil removal needs under different working conditions. The control device 8 also has the power balance control function of the fans 4 to ensure that the power of each fan 4 is balanced and to avoid local overheating or uneven oil removal.

[0027] Understandably, the hot air knife 5 includes blades on both sides, with an angle of 120 degrees between the blades. This angle design allows the hot air knife 5 to form an ideal airflow distribution, ensuring that the hot air evenly covers the aluminum foil surface and effectively guides the oil to flow into the oil storage tank 3. The blades are made of high-temperature resistant alloy material, which has good thermal stability and corrosion resistance, and can maintain stable performance in long-term high-temperature working environments.

[0028] Understandably, the blade tip is positioned on the upper side of the oil storage tank 3. This design allows oil flowing from the blade surface to drip directly into the oil storage tank 3, preventing oil splashing and environmental pollution. The distance between the blade tip and the upper edge of the oil storage tank 3 is calculated to ensure that the oil flows smoothly into the oil storage tank 3, while preventing hot air from blowing directly into the oil storage tank 3 and causing oil splashing. An oil outlet 6 is installed on one side of the oil storage tank 3. The oil outlet 6 is connected to an external oil collection system for regular discharge of collected oil. The oil outlet 6 is detachable for easy cleaning and maintenance. A filter screen is installed at the outlet of the oil outlet 6 to filter out impurities in the oil and extend the service life of the oil collection system.

[0029] Understandably, the oil storage tank 3 is tilted downwards at 35 degrees toward the winding roller 7. This tilting design utilizes gravity to allow the collected oil to flow automatically to the oil outlet tank 6, improving the oil collection efficiency. The tilt angle of the oil storage tank 3 is precisely calculated to ensure that the oil flows smoothly without causing backflow or overflow due to excessive tilting.

[0030] In actual use, the aluminum foil is released from the unwinding roller 9, and the surface oil stains are detected by the detection device 2. Then, it passes through the area of ​​the hot air knife 5. The fan 4 on the hot air knife 5 generates hot air, which is blown onto the surface of the aluminum foil to heat the surface oil stains and reduce the viscosity of the oil stains. At the same time, the oil stains are blown to the oil storage tanks 3 on both sides. The aluminum foil that has been degreased continues to move forward and is finally wound up by the winding roller 7. Throughout the process, the control device 8 adjusts the power of the fan 4 in real time according to the data provided by the detection device 2 to ensure the degreasing effect.

[0031] The hot air knife 5 degreasing mechanism for aluminum foil rolling mill winding in this embodiment achieves efficient removal of oil stains from the aluminum foil surface through reasonable structural design and intelligent control system, improving the surface quality of the aluminum foil and reducing potential problems in subsequent processing. At the same time, the degreasing mechanism is easy to operate and maintain, and can adapt to the degreasing needs of aluminum foil of different specifications, with good practicality and economy.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
