Technical Field

[0001] The utility model relates to the technical field of aluminum foil rolling mills, in particular to a spray device for an aluminum foil rolling mill. Background Art

[0002] Aluminum foil rolling mill is a device used to turn a billet with a thickness of about 0.22mm into aluminum foil with a thickness of less than 0.02mm after several rolling processes. In the production process, the existing high-speed aluminum foil rolling mill usually relies on ironing rollers to assist in coiling to prevent the occurrence of layer-by-layer phenomenon during the coiling process. However, due to the aluminum powder on the surface of the aluminum coil, it is easy to cause aluminum powder accumulation at the ironing roller during the production process, forming defects such as black wire and black line;

[0003] In order to solve the above problems, most existing aluminum foil rolling mills will spray the aluminum foil by setting a spray pipe at the front end of the aluminum foil coiling, and use oil mist spray to clean the aluminum powder on the surface of the aluminum foil to a certain extent, thereby reducing the possibility of black silk and black lines.

[0004] However, in actual applications, due to the different widths of aluminum foils or the different requirements of different aluminum foils on the spray range and strength, it is necessary to replace the appropriate spray tube, which indirectly brings inconvenience to the user.

[0005] In view of this, there is an urgent need for an aluminum foil rolling mill spray device that can solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Please refer to the attached Figure 1-4 , an aluminum foil rolling mill spray device, comprising:

[0026] A spray pipe 1, the spray pipe 1 comprises a mist inlet pipe 10, a main pipe 11 and a plurality of spray diversion pipes 12, the lower end of the mist inlet pipe 10 is fixedly connected to the main pipe 11, and the upper ends of the plurality of spray diversion pipes 12 are fixedly connected to the main pipe 11;

[0027] The device body 2 has mounting ear plates 3 fixedly connected to the device body 2 at both ends of the upper side wall, one of the mounting ear plates 3 is connected to the servo motor 30, and the other mounting ear plate 3 is hinged on the aluminum foil rolling mill frame, and the spray pipe 1 is connected to the device body 2.

[0028] Considering that most of the current spraying methods are to spray directly through pipes, which has the problem that the spray width, range, and angle are difficult to adjust, the device body 2 is used to store the spray tube 2, and the overall angle of the device body 2 is changed through the cooperation of the servo motor 30 and the mounting ear plate 3, thereby achieving the purpose of changing the spray angle. At the same time, the use of the device body 2 is not only conducive to the installation of other related components in the utility model, but also can provide ideas for the installation of other components that may be used in the future.

[0029] Specifically, the device body 2 includes a shell 20, a spray pipe fixing plate 21, a pressing plate 22 and a nozzle plate 23. The spray pipe fixing plate 21 is fixedly connected to the middle position inside the shell 20, and is provided with a plurality of guide channels 210 matching the spray diverter pipe 12. The pressing plate 22 is located at the upper end of the shell 20, and is provided with a through hole 220 for fixing the mist inlet pipe 10, and at least two groups of threaded holes 24 corresponding to the positions are provided on the pressing plate 22 and the spray pipe fixing plate 21. The nozzle plate 23 is located at the lower end of the shell, and is detachably connected to the bottom of the spray pipe fixing plate 21, and the At least one group of nozzles 230 matching the guide channel 210 is provided on the nozzle plate 23; the basic position of the spray tube 1 in the shell 20 is limited by the spray tube fixing plate 21, and the spray tube 1 is completely fixed by the pressure plate 22, and then the nozzle plate 23 is detachably connected to the lower end of the spray tube fixing plate 21, so as to achieve the purpose of changing the physical properties of the spray by replacing the nozzle plate 23, thereby replacing the traditional middle barrel to change the physical properties of the spray by replacing the spray pipeline, simplifying the traditional replacement process, and considering the storage problem, it is obvious that the storage of the nozzle plate 23 is much simpler than the storage of spray pipelines of different specifications.

[0030] Specifically, a rectangular cavity 211 is provided in the spray tube fixing plate 21, and the rectangular cavity 211 is provided with a pressure regulating assembly 25 matched therewith, and the pressure regulating assembly 25 includes an adjusting plate 250, a slide plate 251 and an adjusting handle 252, wherein the slide plate 251 is slidably connected to the housing 20, one end of the adjusting plate 250 is slidably connected to the rectangular cavity 211, and the other end is fixedly connected to the slide plate 251, and an adjusting hole 2500 matching the guide channel 210 is provided on the adjusting plate 250, and one end of the adjusting handle 252 passes through the side wall of the housing 20 and is movably connected to the far end of the slide plate 251. On the side wall of the adjusting plate 250, the adjusting handle 252 is threadedly connected to the shell 20; the rectangular cavity 211 is set to divide the guide channel 210 into two sections, and the pressure regulating component 24 is set to change the actual inner diameter of the guide channel 210 by staggering the adjusting hole 2500 and the guide channel 210 when the adjusting plate 250 is in a different position in the rectangular cavity 211, thereby achieving the purpose of changing the spray pressure, and the application of the slide plate 251 and the adjusting handle 252 allows the above-mentioned adjustment to be performed directly outside the shell 20, avoiding the problem that the device body 2 needs to be disassembled for each adjustment.

[0031] Specifically, the adjustment handle 252 is provided with a mark 2520 on one end outside the housing 20, and the housing 20 is provided with a scale matching the mark 2520; the accuracy of adjustment can be achieved through the mark 2520 on the adjustment handle 252 and the scale matching therewith.

[0032] Specifically, at least two groups of nozzles 230 with different inner diameters are provided on the nozzle plate 23, and at least mounting holes 231 matching the two groups of nozzles 230 are provided on the nozzle plate 23; nozzles 230 of different sizes mean different spray ranges, and multiple groups of nozzles 230 are provided on a single nozzle plate 23, and then the settings of different nozzles 230 are switched by using mounting controls 231 at different positions, which can greatly reduce costs whether in use or storage. It should be noted that the rectangular and circular nozzles 230 in the accompanying drawings are simply provided for the convenience of distinguishing the two groups of nozzles, and do not mean that the shape of the nozzles 230 in actual applications is rectangular. In fact, the nozzles 230 in different groups only differ in size.

[0033] Specifically, the nozzle 230 is provided with a plug that matches it; when it is necessary to adjust the width of the aluminum foil roll, it is only necessary to plug the redundant nozzles 230 with the plug, which is simple, convenient and quick.

[0034] Specifically, the mist inlet pipe 10 is externally connected to a regulating valve for adjusting the pressure; considering that the adjustable range of the pressure regulating component 25 is small and suitable for fine-tuning in a small range, when a larger pressure adjustment is required, the pressure can be adjusted over a large range through an external regulating valve. It is worth noting that, under normal circumstances, the pressure does not need to be adjusted over a large range. When a large range adjustment is performed, the scale matching the mark 2520 is only used as a reference, and the scale cannot be used as accurate pressure data.

[0035] Specifically, the mounting ear plate 3 adopts a sleeve plate structure and is provided with a locking handle 31 for locking the position; by adopting the mounting ear plate 3 with a sleeve plate structure and matching it with the locking handle 31 at the locking position, the actual use height of the mounting ear plate 3 can be changed, thereby achieving the purpose of adjusting the overall height of the device body 2.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
