Description

Technical Field

[0001] The present application relates to the technical field of metal manufacturing, and in particular to an aluminum foil winding device. Background Art

[0002] At present, aluminum foil, as an important metal material, is widely used in food packaging, construction, electronics, aerospace and other fields. The production of aluminum foil mainly depends on rolling technology, which is the key link to achieve metal plastic deformation and improve material performance.

[0003] In the related art, the production process of aluminum foil is to feed aluminum sheets into an aluminum foil rolling mill for rolling, wherein a pair of rotating flattening rollers are installed inside the aluminum foil rolling mill. The gap between the pair of flattening rollers is carefully adjusted to ensure that the aluminum sheet can pass through and is properly compressed. When the aluminum sheet enters the gap, the rotating action of the flattening rollers subjects it to strong pressure. Under the action of pressure, the cross-sectional area of ​​the aluminum sheet gradually decreases, while its length increases accordingly.

[0004] However, the flattening rollers used in aluminum foil rolling mills are usually made of rubber or polyurethane materials, which make the flattening rollers have adsorption properties and are very easy to adsorb aluminum ash during the rolling process. When the aluminum ash accumulates to a certain extent, it will inevitably fall onto the surface of the aluminum foil, forming obvious black oil spots, which directly leads to a decline in product quality. After the flattening rollers made of this material adsorb aluminum ash, it is difficult to clean them by simple wiping. After a period of use, the rubber rollers often need to be replaced or ground, which not only reduces production efficiency, but also increases production costs, causing considerable troubles to aluminum foil production.

[0032] See also Figure 1 , an aluminum foil winding device provided in an embodiment of the present application, includes a box body 1, a winding roller 2, a flattening component 3 and a supporting roller 4.

[0033] Specifically, an open end 11 is provided on the top of the box body 1, and assembly openings 12 are respectively provided on the opposite side walls of the open end 11. In this embodiment, the box body 1 is a frame structure composed of multiple straight rods, and two door panels are respectively installed on the opposite side surfaces of the box body 1. The circumferential side of the box body 1 is an open structure, and two assembly openings 12 are provided at a corner of the top of the box body 1, and the two assembly openings 12 are respectively located on the two door panels.

[0034] The opposite ends of the winding drum 2 are detachably mounted on the two assembly openings 12, and the winding drum 2 can rotate relative to the box body 1, so that the winding drum 2 can roll up the aluminum foil, and when the aluminum foil is rolled up to a calibrated thickness, the entire winding drum 2 can be removed from the box body 1 to facilitate the rolling up of the aluminum foil.

[0035] Combination Figure 1 and Figure 2 As shown, the flattening assembly 3 can be arranged inside the box body 1, and in particular, the flattening assembly 3 is located below the winding drum 2. The flattening assembly 3 includes at least two flattening rollers 31. Both flattening rollers 31 can be rotatably installed on the box body 1, and the two flattening rollers 31 are arranged at intervals so that aluminum foil can pass between the two flattening rollers 31. The two flattening rollers 31 are also parallel to the winding drum 2, so that the aluminum foil can be wound on the winding drum 2 after passing through the gap between the two flattening rollers 31. A layer of high-temperature resistant tape 311 is wrapped around the outer surface of each flattening roller 31. It should be noted that the surface temperature of the flattening roller 31 is about 75°C, and ordinary tape cannot meet the requirements.

[0036] The support roller 4 can be rotatably installed on the top of the box body 1, and the support roller 4 can be arranged parallel to the flattening roller 31, and one end of the support roller 4 is driven and connected to the driving part 41, so that the driving part 41 can drive the support roller 4 to rotate, and the support roller 4 can be supported under the aluminum foil, and drive the aluminum foil into the gap between the two flattening rollers 31. Since a layer of high temperature resistant tape 311 is wrapped around the outer surface of the flattening roller 31, and the high temperature resistant tape 311 can form a smooth protective layer on the surface of the flattening roller 31, the adsorption of the flattening roller 31 can be reduced, and the adsorption of aluminum ash by the flattening roller 31 is greatly reduced. At the same time, it is very convenient to clean, and the grinding frequency of the flattening roller 31 can be reduced, thereby extending the service life.

[0037] See also Figure 2 In some embodiments, the thickness range of the high temperature resistant tape 311 is greater than or equal to 0.1 mm and less than or equal to 0.25 mm. This thickness range can provide good strength, wear resistance, permeability resistance and flexibility, and can meet the working requirements of the flattening roller 31. The specific thickness selection of the high temperature resistant tape 311 should be determined according to actual conditions.

[0038] See also Figure 2 In some embodiments, the high temperature resistant tape 311 can form a straight cylindrical structure on the outer surface of the flattening roller 31 , and opposite ends of the straight cylindrical structure can extend beyond the opposite end surfaces of the flattening roller 31 .

[0039] Specifically, the initial shape of the high temperature resistant tape 311 is square, and the width of the high temperature resistant tape 311 is greater than the cross-sectional circumference of the flattening roller 31, and the length of the high temperature resistant tape 311 is greater than the length of the flattening roller 31. When the high temperature resistant tape 311 is attached to the outer surface of the flattening roller 31, the high temperature resistant tape 311 can completely cover the outer surface of the flattening roller 31, and the high temperature resistant tape 311 is bonded to the flattening roller 31 to form a straight cylindrical structure, and the opposite ends of the flattening roller 31 are also located in the straight cylindrical structure, so that the high temperature resistant tape 311 can fully protect the flattening roller 31 and prevent the flattening roller 31 from absorbing aluminum ash.

[0040] See also Figure 1 and Figure 3 In some embodiments, a rotating portion 21 may be respectively provided at the two opposite ends of the winding drum 2. The rotating portion 21 is a bearing-like structure, and has an inner ring and an outer ring. The inner ring of the rotating portion 21 is sleeved on the outer side of the winding drum 2, and the inner ring of the rotating portion 21 is fixed to the winding drum 2. A rolling groove 22 is provided on the outer ring of the winding drum 2, and the rolling groove 22 is arranged around the outer ring of the winding drum 2.

[0041] The assembly opening 12 can be a notch. Specifically, the assembly opening 12 is an arc-shaped notch, and the assembly opening 12 is adapted to the rotating part 21, so that the rotating part 21 can be detachably installed on the notch, and the side wall constituting the notch can be inserted in the rolling groove 22, so that the rotating part 21 can rotate relative to the box body 1, and the rotating part 21 can drive the winding drum 2 to rotate relative to the box body 1. The side wall constituting the notch and the rolling groove 22 cooperate with each other and can also limit the movement of the rotating part 21 in the axial direction of the winding drum 2. It can also be said that it can prevent the rotating part 21 from moving along the axial direction of the winding drum 2, so that the winding drum 2 rotates more smoothly.

[0042] See also Figure 1 , Figure 3 and Figure 4 In some embodiments, the aluminum foil winding device may further include an oil spraying assembly 5 , which is disposed on the top of the box body 1 , and the oil spraying assembly 5 is disposed in the area between the flattening assembly 3 and the supporting roller 4 .

[0043] Specifically, the oil spraying assembly 5 may include a movable bracket 51 and an oil spraying member 52. The movable bracket 51 may be arranged on the top of the box body 1, and the movable bracket 51 is located above the area between the flattening assembly 3 and the support roller 4, and the oil spraying member 52 is arranged on the movable bracket 51, so that the oil spraying member 52 is also located above the area between the flattening assembly 3 and the support roller 4, so that before the aluminum foil enters the gap between the two flattening rollers 31, the oil spraying member 52 can drip or spray oil onto the aluminum foil, which can remove the aluminum powder on the surface of the aluminum foil and the saponified matter and aluminum powder in the box body 1, so as to keep the aluminum foil clean.

[0044] To be more clear, the oil used in the oil spray part 52 is usually a rolling oil, which also has a lubricating effect. The rolling oil can reduce the friction between the flattening roller 31 and the aluminum foil, provide a stable friction interface, thereby achieving stable flattening and improving the surface quality of the aluminum foil. Moreover, the additives in the rolling oil carry polar groups, which can be firmly adsorbed on the metal surface, thereby achieving separation or basic separation of the flattening roller 31 and the aluminum foil.

[0045] See also Figure 1 and Figure 4 In some embodiments, the movable bracket 51 may include a rotating shaft 511 and a supporting frame 512. The rotating shaft 511 can be rotatably installed on the top of the box body 1, and the supporting frame 512 can be fixed on the rotating shaft 511 so that the supporting frame 512 can extend from the open end 11 to the outside of the box body 1.

[0046] Specifically, the support frame 512 includes two vertical support rods and two transverse support rods, one end of the two vertical support rods are respectively fixed on the rotating shaft 511, and the other ends of the two vertical support rods are respectively connected to the two transverse support rods, and a mounting plate is connected between the two transverse support rods, so that the mounting plate is located above the flattening assembly 3, and the spray member 52 is arranged on the mounting plate, so that the rotating shaft 511 can drive the spray member 52 to move relative to the box body 1, that is, the spray member 52 can move at the top of the box body 1 in a direction perpendicular to the flattening roller 31, and the position of the spray can be adjusted as needed.

[0047] See also Figure 4 and Figure 5 In some embodiments, the movable bracket 51 may further include a fixing member 513 and a limiting member 514. The fixing member 513 may be fixed to the box body 1. In this embodiment, the fixing member 513 is fixed to the inner wall of the box body 1. In other embodiments, the fixing member 513 may also be fixed to the outer wall of the box body 1. A rotating hole may be provided on the fixing member 513 so that one end of the rotating shaft 511 may be rotatably installed on the fixing member 513, and an adjusting hole 5131 may also be provided on the fixing member 513. The adjusting hole 5131 is connected to the rotating hole, or it can be said that the adjusting hole 5131 extends to the rotating connection between the rotating shaft 511 and the fixing member 513.

[0048] The limit member 514 can be threadedly connected to the adjustment hole 5131, so that the limit member 514 can be driven to move along the central axis of the adjustment hole 5131 by rotating the limit member 514. When the rotating shaft 511 drives the injection member 52 to move to the injection position, the limit member 514 can be rotated to drive the limit member 514 to move to abut against the rotating shaft 511, so that the rotation can be fixed so that the limit member 514 is fixed at the injection position, and the rolling oil can be better sprayed onto the aluminum foil.

[0049] See also Figure 1 , Figure 4 and Figure 6 In some embodiments, the oil spraying member 52 may include a nozzle 521 and a baffle 522. The nozzle 521 may be fixed on the movable bracket 51, that is, the nozzle 521 is fixed on the support frame 512, so that the nozzle 521 is located above the flattening roller 31, so that the nozzle 521 can evenly spray the rolling oil onto the aluminum foil.

[0050] The baffle 522 can be installed on the nozzle 521, and the baffle 522 is located on the side of the nozzle 521 facing the winding drum 2. The baffle 522 can effectively prevent the oil splashing generated by the nozzle 521 when spraying oil. Since the baffle 522 is located on the side of the nozzle 521 facing the winding drum 2, it can effectively block the oil sprayed by the nozzle 521 and prevent the nozzle 521 from spraying oil onto the winding drum 2, ensuring that the oil can be accurately sprayed onto the target area instead of splashing everywhere, and the baffle 522 can guide the flow direction of the oil. By installing the baffle 522, the accuracy of the oil injection can be further improved.

[0051] See also Figure 1 and Figure 7 In some embodiments, the aluminum foil winding device may further include a deviation correction component 6 , and the deviation correction component 6 may include a fixed bracket 61 and a deviation correction member 62 .

[0052] Specifically, the fixed bracket 61 can be installed on the top of the box body 1, and the fixed bracket 61 includes two support plates, which are respectively fixed on the opposite side walls of the box body 1, and a guide rod 611 can be provided between the two support plates. The guide rod 611 is a rectangular rod, and the guide rod 611 can be set parallel to the flattening roller 31.

[0053] The deflection correcting member 62 can be slidably installed on the guide rod 611, so that the deflection correcting member 62 can move along the guide rod 611, that is, the deflection correcting member 62 can move in the same direction as the axial direction of the flattening roller 31, and the aluminum foil can be transferred from the deflection correcting member 62 to the winding drum 2. When the aluminum foil is misaligned, the deflection correcting member 62 can be moved to adjust the position of the aluminum foil winding to achieve deflection correction, which is beneficial to improve the neatness of the edge of the aluminum foil roll after winding.

[0054] To be more specific, the deviation correction member 62 may include two movable plates and two rollers. The two movable plates are slidably mounted on the guide rod 611, so that the two movable plates can move along the guide rod 611. The opposite ends of each roller are rotatably connected to the two movable plates, and the two rollers are arranged in sequence at intervals. In this embodiment, the two rollers are parallel to the guide rod 611, and the guide rod 611 is located between the two rollers. The two rollers can be supported under the aluminum foil and guide the aluminum foil to the winding drum 2. Moreover, when the aluminum foil is misaligned during the transmission process, the rollers can be driven to move by the movable plates, thereby adjusting the position of the aluminum foil winding to achieve deviation correction, which is beneficial to improving the neatness of the edge of the aluminum foil roll after winding.

[0055] See also Figure 1 and Figure 7In some embodiments, the correcting component 6 may further include a driving member and a sensing member 63. The driving member can be connected to the correcting member 62 by driving, and the sensing member 63 is installed on the fixed bracket 61. The sensing member 63 can be connected to the driving member signal through the controller, and the sensing member 63 can be used to detect whether the material on the correcting member 62 is offset.

[0056] If the sensing element 63 detects that the material is offset, the sensing element 63 can send a signal to the controller, and the controller can control the driving element to work, and the driving element can drive the correcting element 62 to move in the direction opposite to the direction of material offset, thereby adjusting the position of the material winding to facilitate automatic correction.

[0057] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
