Description

Technical Field

[0001] This utility model relates to the field of aluminum foil oil stain treatment technology, specifically to a foil rolling spraying device for reducing dirty oil spots on the surface of aluminum foil. Background Technology

[0002] Aluminum foil is a very thin aluminum coil, strip, or sheet material obtained by rolling aluminum and aluminum alloy sheets, strips, or coils. The main aluminum foil processing methods include two common routes: hot rolling and twin-roll casting. Regardless of the method, a rolling mill is needed to stretch and reduce its thickness. The rolling mill includes:

[0003] Roughing mill: Used to perform preliminary rolling of aluminum foil blanks to reduce their thickness.

[0004] Intermediate rolling mill: Further rolling of the rough-rolled aluminum foil blank to adjust its thickness and precision.

[0005] Finishing mill: Used to roll aluminum foil into finished products of the required thickness.

[0006] Actual rolling involves multiple sets of rolling mills continuously performing roughing, intermediate rolling, and finishing rolling to form aluminum foil. Reference CN201120075080.9 describes an aluminum foil rolling mill equipped with oil mist nozzles. By rationally controlling the amount of oil sprayed from the nozzles, a uniform oil mist layer is generated on the aluminum foil surface, providing sufficient cooling and lubrication, reducing frictional resistance, increasing rolling speed, reducing rolling defects that may occur during the contact between the aluminum foil surface and the rolls, correcting problems such as poor sheet shape caused by insufficient lubrication, and improving the yield.

[0007] Although the comparative documents reveal the use of oil spraying for lubrication, our battery foil products are primarily used in our customers' high-pressure, high-density products, where the pressure is quite high. Frequent customer feedback regarding localized oil stains and breakage on the aluminum foil surface is related to the roughing and intermediate rolling processes. Generally, due to the high rolling temperature, if the surface oil content is low, the rolling oil quickly solidifies, manifesting as pressed oil stains that are difficult to detect with the naked eye. Furthermore, during the rolling mill, oil can be carried away by the rollers, resulting in uneven oil distribution.

[0008] To address these issues, we provide a foil spraying device that reduces dirty oil spots on the surface of aluminum foil. Utility Model Content

[0009] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a foil rolling spraying device to reduce dirty oil spots on the surface of aluminum foil, thereby solving the technical problem of finished aluminum foil products having dirty oil spots, resulting in rework and property loss.

[0010] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0011] A foil rolling oil spraying device for reducing dirty oil spots on the surface of aluminum foil includes two sets of fixing plates. Oil-resistant plastic tubes are installed on the two sets of fixing plates respectively. Multiple sets of T-connectors are installed on the oil-resistant plastic tubes. Oil spray nozzles are installed at the bottom of the T-connectors on the two sets of oil-resistant plastic tubes. Pressure gauges and valve switches are installed on the two sets of oil-resistant plastic tubes.

[0012] The oil-resistant plastic tube is installed at the mill inlet and is adapted to spray oil onto the aluminum foil surface; the oil-resistant plastic tube is installed at the mill outlet and is adapted to spray oil onto the aluminum foil surface.

[0013] The flow rate of the oil-resistant plastic pipe located at the inlet is greater than that of the oil-resistant plastic pipe located at the outlet.

[0014] In a further technical solution, the fixing plate is a U-shaped channel steel that is bent upwards; multiple sets of position holes and positioning holes are provided on the fixing plate, and the number of position holes is consistent with the number of fuel injectors;

[0015] Pressure rollers are installed on all rolling mills, and pressure roller supports are installed at both ends of the pressure rollers.

[0016] In a further technical solution, the aluminum foil is suitable for rolling by a pressure roller, with the oil nozzle facing the aluminum foil on the pressure roller; the angle between the oil nozzle and the vertical direction at the corresponding position is 10-30°.

[0017] In a further technical solution, the fuel injector is an atomizing fuel injector.

[0018] In a further technical solution, a bottom support plate is also included, which is detachably connected to the fixed plate and detachably connected to the corresponding pressure roller bracket.

[0019] In a further technical solution, both sets of oil-resistant plastic pipes are segmented and connected sequentially to multiple sets of tee connectors; and are sequentially connected to the corresponding pressure gauges and valve switches.

[0020] The bottom support plate includes a folded plate portion and a sleeve portion. The folded plate portion has a connecting hole adapted to the positioning hole, and a positioning bolt is suitable for installation between the positioning hole and the connecting hole. The sleeve portion is integrally connected to the folded plate portion, and the sleeve portion is sleeved on the roller shaft of the upper pressure roller located on the corresponding side.

[0021] In a further technical solution, the sleeve section is fixedly connected to the pressure roller bracket by lateral bolts.

[0022] In a further technical solution, a connecting bearing is installed inside the sleeve, and the outer ring of the connecting bearing is fixedly connected to the sleeve, while the inner ring of the connecting bearing is connected to the corresponding pressure roller shaft.

[0023] A pressure plate is installed on the side of the sleeve section opposite to the angle plate section. A position plate is installed on the corresponding pressure roller bracket. A vertical screw is installed on the position plate, and a top plate is installed on the top of the vertical screw. An adjusting plate is installed on the vertical screw, and an adjusting nut is installed on the adjusting plate, with the adjusting nut threaded onto the vertical screw. A strip-shaped hole is provided on the pressure plate, and the strip-shaped hole is fitted onto the vertical screw. After at least two oil spraying processes on the aluminum foil, the finished product is formed by centrally treating the surface oil, such as with a cleaning agent or organic solvent.

[0024] Compared with existing technologies, it has the following advantages:

[0025] This invention utilizes a spray device with 18 nozzles installed on the flattening roll support at the exit of the roughing and intermediate rolling mills in the foil rolling process. The rolling oil is directly sprayed onto the aluminum foil. By adjusting the valve opening and closing, the spray pressure is controlled within a certain range, ultimately controlling the amount of oil sprayed. This increases the amount of oil on the aluminum foil surface, making it less prone to solidification. When the finished aluminum foil exits the rolling mill, it passes through the inlet and outlet oil sprays. During continuous rolling, this forms an effective oil-protected surface, preventing the formation of dirty oil spots and avoiding batch quality problems. This reduces waste losses caused by severe dirty oil spots on-site and also lowers losses from returns and claims. This invention is simple to manufacture, not easily damaged, and can be used for a long time. It is also easy to operate and understand, making it suitable for online manual use.

[0026] This invention adjusts the position of the adjusting plate on the vertical screw by rotating the screw thread and adjusting the nut against the adjusting plate. This, in turn, presses the pressure plate downward, causing the sleeve to rotate on the pressure roller. This adjusts the angle of the angle plate fixed on the sleeve, which in turn rotates the fixing plate fixed on the angle plate. This, in turn, adjusts the angle of the nozzle on the fixing plate, thus adjusting the spray angle on the aluminum foil. Attached Figure Description

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Example 1

[0041] Please see Figure 1-8 This utility model provides a technical solution: a foil rolling oil spraying device for reducing dirty oil spots on the surface of aluminum foil, comprising two sets of fixing plates 1, on which oil-resistant plastic tubes 2 are respectively installed, and on each of the oil-resistant plastic tubes 2, multiple sets of T-connectors 4 are installed, and oil spray nozzles 5 are installed at the bottom of the T-connectors 4 on the two sets of oil-resistant plastic tubes 2. Figure 3As shown; and pressure gauges 7 and valve switches 8 are installed on both sets of oil-resistant plastic tubes 2; the oil-resistant plastic tubes 2 are installed at the inlet of the rolling mill and are suitable for spraying oil onto the surface of the aluminum foil 9; the oil-resistant plastic tubes 2 are installed at the outlet of the rolling mill and are suitable for spraying oil onto the surface of the aluminum foil 9.

[0042] The flow rate of the oil-resistant plastic tube 2 at the inlet is greater than that at the outlet. The aluminum foil 9 is rolled sequentially from the roughing mill, intermediate mill, and finishing mill, with each layer reducing its thickness. The oil used to reduce friction during the rolling mill is applied to the surface of the aluminum foil, but it's difficult to ensure uniform oil application on the mill. Setting the flow rate ensures continuous oil supply, with a larger flow rate at the inlet to form an oil film on the aluminum foil surface. After rolling, oil is replenished through the oil nozzle at the outlet, providing surface protection for subsequent rolling and preventing the formation of dirty oil spots.

[0043] The specific flow rates at the inlet and outlet need to be tested on the mill over time. In actual use, the flow rate is adjusted by regulating the valve switch. Therefore, the valve switch can be a gate valve, ball valve, or butterfly valve.

[0044] like Figure 2-5 As shown, the fixing plate 1 is a U-shaped channel steel and is bent upwards; multiple sets of position holes 10 and positioning holes 11 are provided on the fixing plate 1, and the number of position holes 10 is consistent with the number of fuel injectors 5;

[0045] Each rolling mill is equipped with a pressure roller 12, and pressure roller supports 13 are provided at both ends of the pressure roller 12. Conventional pressure rollers are equipped with a lifting structure to adjust the thickness of the pressed aluminum foil by raising and lowering the roller. Figure 7 As shown, the lifting structure is not drawn. The aluminum foil 9 is suitable for rolling by the pressure roller 12, and the oil nozzle 5 faces the aluminum foil 9 on the pressure roller 12; the angle between the oil nozzle 5 and the corresponding vertical direction is 10-30°. Figure 1 The angle is displayed as 13°, and the adjustable angle facilitates actual spraying or oil spraying to easily form an oil film. The oil injector 5 is an atomizing oil injector 5. The oil injector 5 can be a MEG fan nozzle, a general-purpose fan nozzle, a deflecting fan nozzle (PZ), a combined fan nozzle (ZHC), or a quick-release nozzle (KC).

[0046] It also includes the bottom support plate 15, such as Figure 4 As shown, the bottom support plate 15 is detachably connected to the fixed plate 1, and the bottom support plate 15 is also detachably connected to the corresponding pressure roller bracket 13. The oil-resistant plastic pipe 2 is segmented, sequentially connecting multiple sets of tee connectors 4; and sequentially connected to the corresponding pressure gauges 7 and valve switches 8; as shown... Figure 4As shown, the bottom support plate 15 includes a folded plate portion 151 and a sleeve portion 152. The folded plate portion 151 has a connecting hole adapted to the positioning hole 11, and a positioning bolt 14 is installed between the positioning hole 11 and the connecting hole. The sleeve portion 152 is integrally connected to the folded plate portion 151, and the sleeve portion 152 is sleeved on the roller shaft of the upper pressure roller 12 located on the corresponding side.

[0047] like Figure 7 The diagram shows a partial cross-sectional view of the connection between the sleeve section 152 and the pressure roller bracket 13. The sleeve section 152 is fixedly connected to the pressure roller bracket 13 by lateral bolts 153. An oil trough can be provided at the bottom of the U-shaped channel steel for oil recovery; this is not shown in this application. The U-shaped channel steel is 8cm wide, has a wall thickness of 5mm, and is 200cm long. It connects to 18 oil injectors and one pressure gauge, installed every 10cm.

[0048] This invention utilizes a spray device with 18 nozzles installed on the flattening roll support at the exit of the roughing and intermediate rolling mills in the foil rolling process to directly spray rolling oil onto the aluminum foil. By adjusting the valve opening and closing, the spray pressure is controlled within a certain range, ultimately controlling the amount of oil sprayed and achieving a mist-like spray. During the coiling process, some of the rolling oil is also drawn into the aluminum coil, increasing the oil content on the aluminum foil surface. Generally, due to the high temperature of the aluminum foil, if the surface oil content is low, the rolling oil on the surface will quickly solidify. This device prevents the rolling oil on the aluminum foil surface from solidifying, avoiding batch quality problems. On the one hand, it reduces waste losses caused by severe oil stains on site, and on the other hand, it reduces losses from returns and claims.

[0049] This utility model is simple to manufacture, not easily damaged, and can be used for a long time; it is also easy to operate, simple and easy to understand, and is conducive to online manual use.

[0050] Example 2

[0051] like Figure 8-10 As shown, another embodiment of this utility model is implemented. Based on embodiment 1, in order to achieve adjustable angle of the fixing plate on the pressure roller, a connecting bearing 16 is installed inside the sleeve part 152, and the outer ring of the connecting bearing 16 is fixedly connected to the sleeve part 152, while the inner ring of the connecting bearing 16 is connected to the roller shaft of the corresponding pressure roller 12.

[0052] like Figure 10As shown, a pressure plate 17 is installed on the side of the sleeve portion 152 opposite to the angle plate portion 151. A position plate 18 is installed on the corresponding pressure roller bracket 13. A vertical screw 19 is installed on the position plate 18, and a top plate 20 is installed on the top of the vertical screw 19. An adjusting plate 21 is installed on the vertical screw 19, and an adjusting nut 22 is installed on the adjusting plate 21, with the adjusting nut 22 threadedly connected to the vertical screw 19. A strip hole 171 is provided on the pressure plate 17, and the strip hole 171 is fitted onto the vertical screw 19. In use, the position of the adjusting nut on the vertical screw is adjusted by rotating the vertical screw thread to abut against the adjusting plate, and the pressure plate is pressed downward, thereby rotating the sleeve portion on the pressure roller. This adjusts the angle of the angle plate portion fixed on the sleeve portion, causing the fixing plate fixed on the angle plate portion to rotate, thereby adjusting the angle of the nozzle on the fixing plate, and thus adjusting the spray angle on the aluminum foil. The slotted hole allows for positional adjustment to achieve the rotation effect of the sleeve section.
