[0001] The present application relates to the technical field of aluminum foil rewinding, and in particular to an aluminum foil rewinding device that is convenient for unloading. Background Art

[0002] Aluminum foil, due to its excellent thermal conductivity, light-blocking properties, and good plasticity, is widely used in a variety of fields, including food packaging, pharmaceutical packaging, and electronic materials. With the continuous growth of market demand, efficiency and quality control in the aluminum foil production and processing industry have become particularly important. Aluminum foil rewinding is a key step in the production process, and its efficiency and convenience directly impact the operation of the entire production line. Therefore, achieving fast and convenient unloading of aluminum foil during the rewinding process is crucial for improving production efficiency, reducing labor intensity, and ensuring product quality.

[0003] Currently, there are two main types of aluminum foil rewinding devices: fixed rewinders and semi-automatic rewinders. Fixed rewinders offer a simple structure and low cost, but they are difficult to adjust and maintain, making them difficult to adapt to diverse production needs. Semi-automatic rewinders reduce operator workload and improve operational convenience to a certain extent, but their degree of automation is limited, requiring manual intervention during reel changes and unloading, and they cannot meet the high-efficiency and high-frequency rewinding requirements of modern factories.

[0004] While existing aluminum foil rewinding equipment has met production needs to a certain extent, several pressing challenges remain. First, traditional aluminum foil rewinding equipment relies on manual operation to change the reels, which not only increases worker workload but also leads to low efficiency in continuous production. Second, while existing semi-automated equipment reduces labor requirements, its low level of automation prevents rapid reels and unloading, making it difficult to adapt to high-frequency production changeovers.

One end of the hopper box 8 is fixedly connected to an electric push rod 10, and the output end of the electric push rod 10 passes through the hopper box 8 and extends to the inside of the feeding trough 9. One end of the U-shaped base 1 is fixedly connected to a conveyor belt 11, which is installed under the I-shaped frame 2, and a friction component is installed at one end of the U-shaped base 1.

[0036] Among them, the conflict assembly includes a conflict slide bar 12 symmetrically slidably connected to one end of the U-shaped base 1, one end of the two conflict slide bars 12 is fixedly connected to a U-shaped mounting head 13, one end of the U-shaped mounting head 13 is rotatably connected to a conflict roller 14, one end of the conflict slide bar 12 is sleeved with a conflict spring 15, the conflict spring 15 is installed between the U-shaped mounting head 13 and the U-shaped base 1, and the conflict roller 14 is installed below the feed trough 9;

[0037] Moreover, the outer fixed sleeve of the resisting roller 14 is provided with a rubber sleeve 16;

[0038] Moreover, a glue storage box 17 is fixedly connected to the top of the U-shaped base 1, and an arc-shaped discharge trough 18 is provided at the bottom of the glue storage box 17. A glue discharge roller 19 is rotatably connected to the inside of the arc-shaped discharge trough 18, and the glue discharge roller 19 forms a rolling fit with the core shaft 7;

[0039] Furthermore, the inner bottom of the glue storage box 17 is evenly provided with a plurality of distribution slots 20 connected to the arc-shaped discharge trough 18;

[0040] Moreover, the rubber discharging roller 19 is configured as an elastic rubber roller;

[0041] Furthermore, a guide ramp 25 is fixedly connected to the interior of the U-shaped base 1 . The guide ramp 25 is installed below the I-beam 2 , and the top of the guide ramp 25 is tilted toward the top of the conveyor belt 11 .

[0042] When in use, first start the driving motor 6 to drive the I-beam 2 to rotate, and make the I-beam 2 drive the core shaft 7 after the rewinding is completed to rotate, and make the core shaft 7 after the rewinding be rolled into contact with the friction roller 14 through the rubber sleeve 16, and squeeze the friction roller 14 to push the U-shaped mounting head 13 to squeeze the friction spring 15 along the length direction of the friction slide bar 12, so that the friction spring 15 produces a contraction deformation, and at the same time makes the rewound core shaft 7 be forced to break away from between the friction disk 3 and the friction ring 4, fall to the top of the guide ramp 25, and slide to the top of the conveyor belt 11 along the inclined direction of the guide ramp 25. At this time, the friction spring 15 produces a rebound deformation, and pushes the friction roller 14 to reset along the length direction of the friction slide bar 12, and then the rewound core shaft 7 is transported to the next process by starting the conveyor belt 11;

[0043] At the same time, the driving motor 6 is continued to be started to drive the I-frame 2 to drive a resistance ring 4 to move to one side of the feeding trough 9. At this time, by placing multiple core shafts 7 into the hopper box 8, under the action of gravity, one core shaft 7 slides into the feeding trough 9, and then the electric push rod 10 is started to push the core shaft 7 out along the length direction of the feeding trough 9, and push the core shaft 7 to pass through the feeding trough 9 and the resistance ring 4, and at the same time, the core shaft 7 pressurized arc-shaped elastic protrusion 5 produces contraction deformation, and then the electric push rod 10 pushes one end of the core shaft 7 to pass through the resistance ring 4 and move to between the resistance disk 3 and the resistance ring 4, so that the arc-shaped elastic protrusion 5 releases the force and rebounds, and pushes the core shaft 7 to be fixed and clamped between the resistance disk 3 and the resistance ring 4, and then continues to start the driving motor 6 to drive the I-frame 2 to drive the core shaft 7 to rotate to the side to be rewound to wait for participation in rewinding;

[0044] In the process of driving the I-frame 2 to drive the core shaft 7 to rotate to the side to be rewound, the I-frame 2 drives the core shaft 7 to form a rolling fit with the glue discharge roller 19. At this time, the core shaft 7 pushes the glue discharge roller 19 to rotate. At the same time, under the action of gravity, the glue inside the glue storage box 17 passes through the distribution groove 20 and flows into the interior of the arc-shaped discharge trough 18. When the glue discharge roller 19 rotates, the surface of the glue discharge roller 19 forms a fit and adhesion with the core shaft 7 to realize automatic gluing of the surface of the core shaft 7, thereby facilitating automatic loading and unloading of the core shaft 7, and effectively improving the production efficiency of the device.

[0045] Reference Figure 1 and Figure 2 、 Figure 4 The bottom of the hopper box 8 is provided with a dividing trough 21 connected to the feeding trough 9, and the inner part of the dividing trough 21 is rotatably connected to the dividing roller 22. The surface of the dividing roller 22 is evenly provided with multiple arc-shaped distribution grooves 23 adapted to the core shaft 7. One end of the hopper box 8 is fixedly connected to a distribution motor 24, and the output end of the distribution motor 24 is fixedly connected to the arc-shaped distribution trough 23.

[0046] During use, when a resistance ring 4 is driven to move to one side of the feed trough 9, the feeding roller 22 is driven to rotate by starting the feeding motor 24, and an arc-shaped feeding trough 23 is driven to wrap a core shaft 7 inside the hopper box 8 and rotate and move to the inside of the feeding trough 21, and a core shaft 7 passes through the inside of the feeding trough 21 and slides into the inside of the feed trough 9, thereby facilitating the quantitative loading of multiple core shafts 7 inside the hopper box 8, further improving the practicality of the device.

[0047] The implementation principle of the aluminum foil rewinding device of the present embodiment is as follows: first, the driving motor 6 is started to drive the I-beam 2 to rotate, and the I-beam 2 drives the core shaft 7 after the rewinding is completed to rotate, and the core shaft 7 after the rewinding is completed forms a rolling conflict with the friction roller 14 through the rubber sleeve 16, and squeezes the friction roller 14 to push the U-shaped mounting head 13 to squeeze the friction spring 15 along the length direction of the friction slide bar 12, so that the friction spring 15 produces a contraction deformation, and at the same time makes the rewound core shaft 7 be forced to break away from between the friction disk 3 and the friction ring 4, fall to the top of the guide ramp 25, and slide to the top of the conveyor belt 11 along the inclined direction of the guide ramp 25. At this time, the friction spring 15 produces a rebound deformation, and pushes the friction roller 14 to reset along the length direction of the friction slide bar 12, and then the rewound core shaft 7 is transported to the next process by starting the conveyor belt 11;

[0048] Then continue to start the driving motor 6 to drive the I-frame 2 to drive a resistance ring 4 to move to one side of the feeding trough 9, at this time, the feeding motor 24 is started to drive the feeding roller 22 to rotate, and drive an arc-shaped feeding trough 23 to wrap a core shaft 7 inside the hopper box 8 to rotate and move to the inside of the feeding trough 21, and make a core shaft 7 pass through the inside of the feeding trough 21 and slide into the inside of the feeding trough 9, and then start the electric push rod 10 to push the core shaft 7 along the length direction of the feeding trough 9, and push the core shaft 7 to pass through the feeding trough 9 and the resistance ring 4, at the same time, the core shaft 7 pressurized arc-shaped elastic protrusion 5 produces contraction deformation, and then the electric push rod 10 pushes one end of the core shaft 7 to pass through the resistance ring 4 and move between the resistance disk 3 and the resistance ring 4, so that the arc-shaped elastic protrusion 5 is relieved of the force and rebounds, and pushes the core shaft 7 to be fixed and clamped between the resistance disk 3 and the resistance ring 4, and then continue to start the driving motor 6 to drive the I-frame 2 to drive the core shaft 7 to rotate to the side to be rewound to wait for rewinding;

[0049] In the process of driving the I-frame 2 to drive the core shaft 7 to rotate to the side to be rewound, the I-frame 2 drives the core shaft 7 to form a rolling fit with the glue discharge roller 19. At this time, the core shaft 7 pushes the glue discharge roller 19 to rotate. At the same time, under the action of gravity, the glue inside the glue storage box 17 passes through the distribution groove 20 and flows into the interior of the arc-shaped discharge trough 18. When the glue discharge roller 19 rotates, the surface of the glue discharge roller 19 forms a fit and adhesion with the core shaft 7, so as to realize automatic gluing of the surface of the core shaft 7.
