Description

Technical Field

[0001] The utility model relates to the technical field of oil removal devices, in particular to an oil removal device for the rolled surface of an alloy aluminum foil used for a loudspeaker cone. Background Art

[0002] The speaker cone is a key component in the speaker that converts electrical energy into sound energy, and alloy aluminum foil is an aluminum foil made of an alloy composed of aluminum and other metal elements. During the aluminum foil rolling process, especially for alloy aluminum foil used for speaker cones, rolling is often accompanied by the use of a large amount of process lubricants. These lubricants will adhere to the surface of the aluminum foil during the rolling process. If effective degreasing treatment is not carried out, these oil stains will not only affect the surface quality of the aluminum foil, but may also have an adverse effect on subsequent processing and use. These oil stains not only affect the cleanliness of the aluminum foil, but may also affect the quality and performance of the speaker cone.

[0003] After searching, the Chinese patent application number CN202223368685.4 discloses an aluminum foil surface degreasing device. In the process of degreasing and conveying the aluminum foil, the aluminum foil will be pulled and a certain tension will be generated during the conveying process. The excessive tension may cause the aluminum foil to be torn, thereby damaging the aluminum foil and affecting the degreasing process. Therefore, the degreasing agent is pumped into the degreasing roller by a water pump, and the degreasing cotton quickly absorbs the degreasing agent and stores it in the degreasing cotton. The electric push rod pushes the slider up and down in the slide rail, thereby driving the degreasing rollers on the upper and lower sides to move toward each other, and then the degreasing rollers on the upper and lower sides squeeze each other and squeeze the degreasing cotton, so that the degreasing agent in the degreasing cotton is squeezed out, thereby effectively degreasing the upper and lower surfaces of the aluminum foil. The electric push rods on the upper and lower sides drive the degreasing rollers up and down to effectively adjust the height of the aluminum foil conveyance, thereby reducing the tension on the aluminum foil during the conveying process and causing certain damage to the aluminum foil.

[0004] In the above-mentioned process of degreasing the surface of the aluminum foil, the aluminum foil is degreased using degreasing cotton and a degreasing agent. The degreasing efficiency is low, and more degreasing agents need to be used and the degreasing cotton needs to be replaced frequently, which can easily increase the degreasing cost. In the prior art, an air blowing device with a temperature of 75-95°C is usually added to the aluminum foil rolling mill. When blowing the aluminum foil, the blowing air outlet is usually in a fixed state, which is not convenient for flexibly adjusting the angle of the air outlet according to the required blowing range and angle, which can easily lead to a decrease in the quality of blowing, thereby reducing work efficiency.

The rotatably connected air outlet 9 is convenient for rotating to the required air outlet angle, and the cooperation between the cross slot 10 and the cross block 14 is convenient for limiting and fixing the position of the air outlet 9 after rotation, and the spring 15 is convenient for pushing the cross block 14 engaged with the cross slot 10, thereby improving the tightness of the cross block 14.

[0034] As attached Figure 2 As shown, an inclined groove 16 is provided in the middle of the bottom plate 1, and drainage grooves 17 are provided at both ends of the bottom plate 1. A filter plate 18 is fixedly connected to the top of the inclined groove 16, and mounting strips 19 are fixedly connected to both sides of the filter plate 18. The setting of the inclined groove 16 facilitates the collected oil to flow along the inclined surface to the inside of the drain pipe 23, and the filter plate 18 facilitates filtering the dripping oil.

[0035] As attached Figure 7As shown, the interior of the mounting bar 19 is slidably connected to a slider 20, the exterior of the two sliders 20 is fixedly connected to an anti-blocking brush 21, the top of the anti-blocking brush 21 is fixedly connected to a handle 22, and the two sliders 20 drive the anti-blocking brush 21 to slide inside the mounting bar 19. The contact between the bottom of the anti-blocking brush 21 and the top of the filter plate 18 facilitates cleaning of dirt on the surface of the filter plate 18.

[0036] As attached Figure 3 As shown, a drain pipe 23 is fixedly connected to the bottom of the drain trough 17, and a dust blocking plate 24 is fixedly connected to the other end of the mounting tube 4. The dust blocking plate 24 facilitates dust protection for the fan 5, thereby extending the service life of the fan 5.

[0037] As attached Figure 1 As shown, a mounting bracket 25 is fixedly connected to the middle of the base plate 1, two oil scraping rollers 26 are fixedly connected to the inside of the mounting bracket 25, and two cleaning rollers 28 are rotatably connected to one side of the mounting bracket 25. The cleaning roller 28 is convenient for using the soft brush on the surface to clean the oil stains after blowing, thereby improving the degreasing quality.

[0038] As attached Figure 8 As shown, one side of the two oil scraping rollers 26 is provided with a plurality of scraping strips 27 made of rubber material, which is conducive to further cleaning the oil stains.

[0039] Working principle: When removing oil stains from the surface of the aluminum foil, first turn on the heating nets 8 on both sides to preheat the heating nets 8, turn on the fan 5, and let the fan 5 suck air through the dust blocking plate 24, and suck the wind into the installation pipe 4 and the circulation pipe 6. When the wind reaches the inside of the circulation pipe 6, the wind will disperse and flow to the two ends of the circulation pipe 6, and then enter the inside of the air supply pipe 7. When the wind passes through the heating net 8, the heat of the heating net 8 will be transferred out, and the hot wind will be transferred out through the air outlet 9. Then the aluminum foil is wound into the unwinding roller 2, and the other end of the aluminum foil is passed through the two cleaning rollers 28 and two scrapers. After the oil roller 26, it is wound into the surface of the winding roller 3, and then the winding roller 3 and the unwinding roller 2 are turned on to rotate. When the aluminum foil is in the process of being conveyed, the hot air is blown to clean the oil on the surface of the aluminum foil, thereby achieving surface cleaning. When the aluminum foil passes through the two cleaning rollers 28 and the oil scraping roller 26, the rotating cleaning roller 28 is used to clean the oil remaining after the hot air blowing. The scraping strip 27 on one side of the oil scraping roller 26 is then used to scrape off the oil on the surface of the aluminum foil, causing the oil to drip, thereby enhancing the cleaning function of the oil on the surface of the aluminum foil. When the angle of the air outlet 9 needs to be adjusted When the air outlet is in the air-gap position, the two pull rods 12 are pulled, so that the pull rods 12 drive the sliding plate 13 to drive the cross block 14 to slide into the interior of the fixed box 11, so that the cross block 14 is released from the corresponding cross slot 10, thereby releasing the limiting effect of the air outlet head 9, and then rotating the air outlet head 9 to facilitate the adjustment of the air outlet angle of the air outlet head 9. When the adjustment is completed, the pulled pull rods 12 are released, and the rebound action of the two springs 15 facilitates the rebound push of the cross block 14, thereby pushing the cross block 14 to engage with the corresponding cross slot 10, thereby facilitating the adjustment of the angle of the air outlet head 9 and improving the adaptability to the aluminum foil. When the cleaned oil drops onto the filter plate 18, the impurities will remain on the surface of the filter plate 18, and the liquid will pass through the filter plate 18 to reach the inside of the oblique groove 16, which is convenient for collecting the liquid, and then discharge the liquid inside the oblique groove 16 through the drain pipe 23. When it is necessary to clean the impurities on the surface of the filter plate 18, pull the handle 22 so that the handle 22 can drive the anti-blocking brush 21 to drive the sliders 20 at both ends to slide inside the mounting strips 19 on both sides, so that the impurities on the surface of the filter plate 18 can be brushed into the inside of the drain trough 17 by the anti-blocking brush 21, thereby maintaining the patency of the filter holes in the filter plate 18.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
