Description

Technical Field

[0001] This utility model relates to the field of aluminum foil processing technology, specifically to a spray device for cleaning oil stains from aluminum coils. Background Technology

[0002] Aluminum foil is a hot stamping material made by directly rolling metallic aluminum into thin sheets. Its stamping effect is similar to that of pure silver foil, hence it is also called imitation silver foil. Because aluminum is soft, malleable, and has a silvery-white luster, if the rolled sheets are laminated onto offset paper with substances such as sodium silicate to form aluminum foil sheets, they can also be printed on. During the production process, the surface of aluminum foil is prone to adhering to oil and other stains, so surface cleaning is often required before leaving the factory. Currently, cleaning the surface of aluminum foil uses cleaning brushes or scrapers. Cleaning brushes often only rotate back and forth, while scrapers move in a straight line in one direction. For some high-precision aluminum foils, this may damage the surface and cause losses. Therefore, a spray device for cleaning oil stains from aluminum coils is proposed.

[0003] Patent CN222020173U discloses a surface treatment device for aluminum foil product processing, including: a frame including a base plate, and a side plate fixedly connected to the upper surface of the base plate. This utility model uses a motor to start, causing two sets of sliders to slide in the inner side of the slide groove towards each other, thereby causing the two sets of moving plates to approach each other, so that the upper and lower oil-absorbing rollers can contact the aluminum foil body and apply a small pressure to the aluminum foil body. The two sets of oil-scraping plates can clamp the aluminum foil body in the middle of the two sets of oil-scraping plates. The two sets of oil-scraping plates can first scrape off obvious oil stains on the surface of the aluminum foil body. However, the use of scrapers for cleaning is not effective in actual use and affects the surface quality of the aluminum foil. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a spray device for cleaning oil stains on aluminum coils. It uses spray cleaning, which does not damage the surface of aluminum foil. The spray atomization intensity can be adjusted according to actual needs. The spray pipe is easy and quick to install. The spray pipe angle can also be changed by rotating the spray pipe with a lever, which can change the spray angle of the nozzle to meet different usage scenarios. It can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spraying device for cleaning oil stains from aluminum coils, comprising a frame, with connecting plates hinged to both sides of the frame, and spraying components fastened to the ends of the two connecting plates. The spraying components are located above the aluminum foil and perpendicular to the direction of travel of the aluminum foil. A drive device for driving the corresponding connecting plates to swing is provided on one side wall of the frame. The spraying components include a spray pipe, with multiple nozzles linearly arrayed along the length of the lower part of the spray pipe. The spray pipe is connected to an interface, and the interface is connected to a flexible hose, which is connected to an external liquid supply system.

[0006] Preferably, the connecting plate is connected to the frame by a bolt and nut assembly, and both the connecting plate and the frame are provided with through holes for the bolts of the bolt and nut assembly to pass through; the two connecting plates are also connected by a support plate.

[0007] Preferably, the end of the connecting plate is provided with a U-shaped groove, the diameter of which is larger than the diameter of the spray pipe, and both sides of the U-shaped groove are provided with fastening bolts for fixing the spray pipe in the U-shaped groove.

[0008] Preferably, the pipe wall of the spray pipe is provided with baffles on both sides corresponding to the nozzle, the baffles are parallel to the axis of the spray pipe, and the two baffles open downwards and gradually increase in size.

[0009] Preferably, the driving device is one of an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder, with the cylinder end of the driving device hinged to the side wall of the frame and the telescopic end of the driving device hinged to the connecting plate.

[0010] Preferably, the spray pipe is further provided with a lever on its wall.

[0011] Compared with the prior art, the beneficial effects of this utility model are: it uses spray cleaning, which does not damage the surface of aluminum foil; the connecting plate swings around its hinge point through the driving device, and the two connecting plates drive the spray assembly to swing, thereby changing the distance between the nozzle at the bottom of the spray pipe and the aluminum foil, so that the intensity of spray atomization can be adjusted according to actual needs; the spray pipe is clamped in the U-shaped groove by two fastening bolts, and the spray pipe is easy and quick to install; the spray pipe angle can also be changed by rotating the spray pipe with the lever, thereby changing the spray angle of the nozzle, and spraying the aluminum foil to remove oil stains as needed.

The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0018] Please see Figure 1-4 The present invention provides the following technical solution:

[0019] Example 1: A spraying device for cleaning oil stains on aluminum coils includes a frame 1, with connecting plates 2 hinged to both sides of the frame 1. Spraying components 4 are clamped at the ends of the two connecting plates 2. The spraying components 4 are located above the aluminum foil and perpendicular to the direction of travel of the aluminum foil. A drive device 3 for driving the corresponding connecting plates 2 to swing is provided on one side wall of the frame 1. The spraying components 4 include a spray pipe 4.1. Multiple nozzles 4.2 are linearly arrayed along the length of the lower part of the spray pipe 4.1. The spray pipe 4.1 is connected to an interface 4.4. The interface 4.4 is connected to a hose 4.5. The hose 4.5 is connected to an external liquid supply system.

[0020] Spray cleaning is used without damaging the aluminum foil surface. The connecting plate 2 swings around its hinge point through the drive device 3. The two connecting plates 2 drive the spray assembly 4 to swing, thereby changing the distance between the nozzle 4.2 at the bottom of the spray pipe 4.1 and the aluminum foil. This allows the spray atomization intensity to be adjusted according to actual needs. The interface 4.4 is connected to the external liquid supply system through the hose 4.5. The purpose of using the hose 4.5 is to accommodate the swing of the spray pipe 4.1. The external liquid supply system includes a water tank and a water pump. The water pump draws the cleaning agent in the water tank and delivers it to the spray pipe 4.1 for spraying.

[0021] Specifically, the drive device 3 is one of an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder. The cylinder end of the drive device 3 is hinged to the side wall of the frame 1, and the telescopic end of the drive device 3 is hinged to the connecting plate 2.

[0022] Example 2: Unlike Example 1, the connecting plate 2 is connected to the frame 1 by a bolt and nut assembly 2.2. Both the connecting plate 2 and the frame 1 are provided with through holes for the bolts of the bolt and nut assembly 2.2 to pass through, which facilitates installation and disassembly. The two connecting plates 2 are also connected by a support plate 2.1, which makes the whole more solid. When one connecting plate 2 swings, it can drive the other connecting plate 2 to swing through the support plate 2.1.

[0023] Example 3: Unlike Example 1, the end of the connecting plate 2 is provided with a U-shaped groove 2.3. The diameter of the U-shaped groove 2.3 is larger than the diameter of the spray pipe 4.1. Both sides of the U-shaped groove 2.3 are provided with fastening bolts 2.4 for fixing the spray pipe 4.1 in the U-shaped groove 2.3. The spray pipe 4.1 is clamped in the U-shaped groove 2.3 by two fastening bolts 2.4, making the installation of the spray pipe 4.1 convenient and quick.

[0024] Example 4: Unlike Example 1, the pipe wall of the spray pipe 4.1 is provided with baffles 4.6 on both sides corresponding to the nozzle 4.2. The baffles 4.6 are parallel to the axis of the spray pipe 4.1. The two baffles 4.6 open downward and gradually increase in size, which can prevent the mist from splashing and concentrate the mist onto the aluminum foil.

[0025] In addition, the pipe wall of the spray pipe 4.1 is also equipped with a lever 4.3. Loosen the fastening bolt 2.4 and rotate the spray pipe 4.1 by lever 4.3 to change the angle of the spray pipe 4.1, thereby changing the spray angle of the nozzle 4.2.

[0026] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
