Description

Technical Field

[0001] This utility model relates to the field of aluminum sheet and strip rewinding technology, specifically to a deviation correction device for an aluminum sheet and strip rewinding machine. Background Technology

[0002] Aluminum sheet and strip, as an important metal material, has a wide range of applications in many fields. Among them, it plays a crucial role in the beer packaging industry. For example, the pull-tab on beer cans, as an easy-open cap that requires no bottle opener, is highly favored by the market due to its unique advantages and has a bright market prospect. In the actual production process, the aluminum sheet and strip rewinding machine is a key piece of equipment in the production of easy-open caps. A correction device for aluminum sheet and strip rewinding machines is usually used to ensure that the edges of the aluminum sheet and strip remain neat and aligned during the rewinding process, so as to avoid material waste and damage. For example, the correction device for rewinding machines with announcement number CN221478977U, through the limit mechanism and speed adjustment mechanism, performs longitudinal and transverse position correction before the raw material is rewound, avoiding the phenomenon of the raw material running off track when entering the rewinding roller, thereby avoiding machine jams and misalignment of the rewound roll, improving work efficiency and ensuring product quality.

[0003] While the aforementioned technology can straighten the longitudinal and transverse positions of the raw material before rewinding, preventing deviation when the material enters the rewinding roller, it has the problem of not being able to clean the aluminum strip during rewinding. Dirt, grease, or other impurities may remain on the surface of the aluminum strip, which will reduce the surface quality of the finished product, affecting its appearance and performance. The dirt may also cause the aluminum strip to stick together during the rewinding process, forming an uneven coil, which will affect subsequent processing. Utility Model Content

[0011] Preferably, flexible pads are provided on the sides of the two striking plates that are close to each other, and the two eccentric discs are located at the center of the two striking plates respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] (1) By setting the reciprocating screw to drive the reciprocating block and scraper to move back and forth, the surface impurities of the aluminum strip can be scraped off when the aluminum strip is rewound, thereby improving the surface smoothness of the aluminum strip. The cleaned aluminum strip will have fewer defects in subsequent processing, reducing the scrap rate and thus reducing production losses. It can also prevent corrosion and oxidation, extend the service life of the aluminum strip, and reduce maintenance costs.

[0014] (2) By setting the tapping component, the surface of the aluminum strip is tapped and vibrated, which can effectively loosen and remove dust, dirt and other attachments on the surface of the aluminum strip. It can also help disperse stress, reduce the risk of deformation of the aluminum strip during the rewinding process, and ensure its straightness.

[0015] (3) By setting the adjustment components, the tension of the aluminum strip can be adjusted during rewinding. Appropriate tension can prevent the aluminum strip from bending or wavy deformation during rewinding, ensure the flatness of the final roll, avoid excessive tension causing the aluminum strip to tear, and avoid insufficient tension causing instability during rewinding.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] This utility model provides the following technical solution: a deviation correction device for an aluminum sheet and strip rewinding machine.

[0025] Example 1: By setting up scraper 9 and tapping components, the surface of the aluminum strip can be cleaned, such as... Figures 1-4 and Figure 6As shown, the system includes a base plate 1, a first support plate 2 fixedly connected to the top of the base plate 1, a first drive motor mounted on one end of the first support plate 2, and an air shaft 3 provided at the output end of the first drive motor, which is rotatably connected inside the first support plate 2; a second support plate 4 is also fixedly connected to the top of the base plate 1, a first rotating gear 5 fixedly connected to one end of the air shaft 3, two second rotating gears 6 meshing with each other on the first rotating gear 5, and reciprocating screws 7 provided on the gear shafts of the two second rotating gears 6, which are rotatably connected to the second support plate 4; reciprocating blocks 8 are threadedly connected to the outer surfaces of the two reciprocating screws 7, and limiting rods provided between the first support plate 2 and the second support plate 4 are slidably connected inside the two reciprocating blocks 8; hollow blocks are provided at the ends of the two reciprocating blocks 8 that are close to each other, and scrapers 9 are provided inside the two hollow blocks; a striking assembly for striking the aluminum strip is provided on the reciprocating screws 7, and the striking assembly includes four third support plates 10. Four third support plates 10 are respectively located at the two ends of the first support plate 2 and the second support plate 4, and each of the four third support plates 10 is provided with a first spring 11 at the end close to each other. The first spring 11 on both sides is provided with a striking plate 12 at the end close to each other. The second support plate 4 is provided with a vibration assembly that drives the striking plate 12 to vibrate. The vibration assembly includes two rotating shafts 13, which are rotatably connected to the two ends of the second support plate 4. Each of the two rotating shafts 13 is provided with an eccentric disk 14 at the end away from the second support plate 4. Each of the two reciprocating screws 7 is provided with a rotating column at one end, and each of the two rotating columns and the two rotating shafts 13 is provided with a synchronous pulley. A synchronous belt 15 is provided between the two synchronous pulleys. A row of second springs 22 is provided between the top of the two scrapers 9 and the top of the two hollow blocks, and the row of second springs 22 is equidistantly distributed. Each of the two striking plates 12 is provided with a flexible pad on the side close to each other, and the two eccentric disks 14 are respectively located at the center of the two striking plates 12.

[0026] A rewinding roller is placed on the air shaft 3. Then, one end of the aluminum strip is passed between the two striking plates 12 and the two scrapers 9 and fixed to the rewinding roller. The first drive motor is then started, causing the air shaft 3 and the rewinding roller to rotate, thereby rewinding the aluminum strip. The rotation of the air shaft 3 also drives the first rotating gear 5 to rotate, thereby driving the two reciprocating lead screws 7 and the rotating column to rotate. Then, under the action of the synchronous pulley and the synchronous belt 15, it drives the two rotating shafts 13 to rotate, thereby causing the eccentric disc 14 to strike the striking plates. 12. The impacted striking plate 12 will reciprocate under the action of the first spring 11 and continuously strike the aluminum strip to vibrate and clean the impurities on its surface. The flexible pad can prevent the aluminum strip from being damaged when it is struck. The rotation of the reciprocating screw 7 will also drive the two reciprocating blocks 8 and the hollow block to reciprocate under the action of the limit rod, thereby driving the two scrapers 9 to reciprocate on the surface of the aluminum strip and scrape off the impurities remaining on its surface. The second spring 22 can make the scrapers 9 adapt to aluminum strips of different thicknesses.

[0027] Example 2: Unlike Example 1, the adjustable component can be used to adjust the tension of the aluminum strip during rewinding, such as... Figure 1 , Figure 2 and Figure 5 As shown, the top of the base plate 1 is provided with an adjustment component for adjusting the tension of the aluminum strip during rewinding. The adjustment component includes a hollow frame 16, which is located on the top of the base plate 1. Both ends of the hollow frame 16 are slidably connected to rotating seats, and an electric telescopic rod 17 is rotatably connected between the two rotating seats. Each of the two rotating seats is provided with a tension roller 18 at one end.

[0028] When it is necessary to adjust the tension of the aluminum strip, the electric telescopic rod 17 can be activated to drive the two rotating seats to move closer or further apart inside the hollow frame 16, thereby changing the height of the two tensioning rollers 18 and thus adjusting the tension of the aluminum strip.

[0029] Example 3: Unlike Example 2, the correction component can prevent the aluminum strip from shifting during rewinding, such as... Figure 1 and Figure 2 As shown, the top of the base plate 1 is also provided with a correction component for correcting the aluminum strip. The correction component includes a support frame 19, which is located on the top of the base plate 1. Two sliders are slidably connected inside the support frame 19, and each slider is provided with a correction roller 20 on its top. One end of the support frame 19 is provided with a second drive motor, and the output end of the second drive motor is provided with a bidirectional lead screw 21. The bidirectional lead screw 21 is rotatably connected inside the support frame 19, and the threads at both ends of the bidirectional lead screw 21 are respectively threaded into the two sliders.

[0030] When the aluminum strip is rewinding, the second drive motor can be started to drive the bidirectional lead screw 21 to rotate, which in turn drives the two sliders to move closer or further apart, thereby changing the distance between the two straightening rollers 20. This adapts to aluminum strips of different widths, ensuring that the aluminum strip remains in the center position during rewinding and preventing it from shifting.
