Description

Technical Field

[0001] This utility model relates to the field of aluminum foil cutting and rewinding technology, specifically to an aluminum foil cutting and rewinding device. Background Technology

[0002] Aluminum foil cutting and rewinding is a key process in aluminum foil processing. It refers to the process of precisely cutting large-size raw aluminum foil rolls according to preset width, length and other specifications using professional cutting equipment, and then rewinding them into smaller rolls that meet the needs of downstream applications. This process satisfies the specific size requirements of aluminum foil in different industries such as packaging, electronics, construction, and home appliances. It is an important intermediate link from aluminum foil production to end application.

[0003] When processing aluminum foil using a slitting machine, the aluminum foil may break due to excessive tension, sudden imbalance in winding and unwinding speeds, or defects in the cutting tool, hidden cracks in the aluminum foil itself, or uneven thickness. Aluminum foil breakage can cause an instantaneous interruption in production. The sudden change in tension at the time of breakage can cause the already wound roll to become loose, wrinkled, or have misaligned ends, resulting in material waste and reduced production efficiency. To address this, we propose an aluminum foil cutting and rewinding device. Utility Model Content

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.

[0029] Please see Figure 1-2This utility model provides a technical solution: an aluminum foil cutting and rewinding device, including a slitting machine 1, a roll 2 mounted on the surface of the slitting machine 1, and a limiting structure 3 on the surface of the slitting machine 1. By setting the limiting structure 3, the aluminum foil is continuously and stably compressed, preventing the rolled aluminum foil from becoming loose after it breaks. The surface of the slitting machine 1 is provided with a protective structure 4. By setting the protective structure 4, when the equipment is running, the protective cover 44 is moved to a position covering the processing area of ​​the slitting machine 1 by rotating the threaded rod 42, forming a physical barrier. In the event of an accidental breakage, the protective structure 4 can effectively prevent the spread of fragments, protecting the equipment and the safety of the operators.

[0030] Reference Figure 3 and Figure 4 As shown in this embodiment: the limiting structure 3 includes two supports 31, both of which are fixedly connected to the surface of the slitting machine 1. A pressure rod 32 slides through the surface of the support 31. A pressure plate 33 is fixedly connected to one end of the pressure rod 32 near the roll 2. A spring 34 is fitted onto the arc surface of the pressure rod 32, and both ends of the spring 34 are fixedly connected to the pressure rod 32 and the support 31, respectively. Two limiting rods 35 slide through the surface of the pressure plate 33, both of which are fixedly connected to the surface of the pressure plate 33. The limiting rods 35 provide precise guidance for the movement of the pressure plate 33, preventing the pressure plate 33 from tilting under pressure and ensuring a uniform distribution of the clamping force on the aluminum foil. Several arc-shaped strips 36 are fixedly connected to the side of the pressure plate 33 near the roll 2. The arc-shaped strips 36 on the side of the pressure plate 33 near the roll 2 increase the contact friction with the aluminum foil, further improving the limiting effect on the aluminum foil. An extension arm 37 is fixedly connected to one side of the bracket 31. A rectangular rod 38 slides through the surface of the extension arm 37. A support plate 39 is fixedly connected to one end of the rectangular rod 38. The support plate 39 restricts the pressure plate 33, thereby facilitating the limiting of the pressure plate 33 and avoiding the need to continuously pull the pressure rod 32 when installing or disassembling the roll material.

[0031] Reference Figure 5As shown, specifically, the protective structure 4 includes two fixed plates 41. Threaded rods 42 are rotatably connected to the surfaces of the two fixed plates 41. A drive plate 43 is threadedly connected to the surface of the threaded rod 42. A protective cover 44 is fixedly connected to the surface of the drive plate 43. The size of the protective cover 44 is adapted to the size of the slitting machine 1. Two extension plates 45 are fixedly connected to the surface of the slitting machine 1. A guide rod 46 is fixedly connected to one side of the two extension plates 45 that is close to each other. A guide plate 47 is slidably connected to the surface of the guide rod 46. The guide plate 47 is fixedly connected to the surface of the protective cover 44. The guide plate 47 slidably connected to the surface of the guide rod 46 is fixed to the protective cover 44, ensuring that the protective cover 44 moves smoothly along a straight line during movement, avoiding deviation and jamming. A turntable 48 is fixedly connected to one end of the threaded rod 42. The vertical cross-section of the turntable 48 is cross-shaped. The cross-shaped turntable 48 at the end of the threaded rod 42 increases the hand application point, making it easier for the operator to easily rotate the threaded rod 42 to adjust the position of the protective cover 44, improving operational convenience.

[0032] Working Principle: The slitting machine 1 is the core equipment. The roller 2 mounted on its surface is responsible for supporting and winding the aluminum foil roll. During processing, the original aluminum foil roll is mounted on the roller 2. The drive mechanism of the slitting machine 1 drives the roller 2 to rotate, so that the aluminum foil is smoothly conveyed to the cutting mechanism under tension. The cutting mechanism precisely cuts the aluminum foil according to the preset specifications. The cut aluminum foil is then rewound by the other roller 2 into a small roll that meets the requirements, completing the core process of cutting and rewinding. During the cutting and rewinding process of the aluminum foil, two supports 31 are fixed to the surface of the slitting machine 1. The pressure rod 32 passing through it always applies pressure to the roller 2 under the elastic force of the spring 34, causing the pressure plate 33 at the end of the pressure rod 32 to fit tightly against the surface of the aluminum foil. Several arc-shaped strips 36 on the side of the pressure plate 33 near the roller 2 increase the contact friction with the aluminum foil. The friction further enhances the limiting effect on the aluminum foil, reducing relative slippage during the winding process. The limiting rod 35, which slides through the surface of the pressure plate 33, is fixed to the pressure plate 33, providing precise guidance for its movement and preventing it from tilting under pressure. This ensures a uniform distribution of the clamping force on the aluminum foil. When installing or removing the aluminum foil roll, the pressure rod 32 is pulled away from the roll 2. The pressure rod 32 then moves the pressure plate 33 away from the roll 2. Once the pressure plate 33 reaches the appropriate height, the rectangular rod 38 is pushed. The rectangular rod 38 moves the support plate 39 below the pressure plate 33. At this point, the pressure plate 33 is released, and the support plate 39 restricts its movement, thus facilitating the limiting of the pressure plate 33 and avoiding the need to continuously pull the pressure rod 32 during installation or removal of the roll.

[0033] The fixed plate 41 on the surface of the slitting machine 1 supports the threaded rod 42. When the threaded rod 42 is rotated, the drive plate 43 connected to its surface drives the protective cover 44 to move horizontally. When the equipment is running, the protective cover 44 is moved to a position covering the processing area of ​​the slitting machine 1 by rotating the threaded rod 42, forming a physical barrier to prevent fragments from flying when the aluminum foil breaks or to prevent operators from accidentally touching dangerous parts. The extension plate 45 on the surface of the slitting machine 1 fixes the guide rod 46. The guide plate 47 slidably connected to the surface of the guide rod 46 is fixed to the protective cover 44 to ensure that the protective cover 44 runs smoothly in a straight line during movement and avoids deviation and jamming. The cross-shaped turntable 48 at the end of the threaded rod 42 increases the hand application point, making it convenient for operators to easily rotate the threaded rod 42 to adjust the position of the protective cover 44 and improve the ease of operation.
