Among them, the workbench 11 is slidably connected to the lifting shaft 15 through a guide rod fixed on its upper surface, and the circumferential outer surface of the lifting shaft 15 is sleeved with a tension wheel 151. The side of the sliding seat 12 away from the rotating shaft 13 is provided with a tension adjustment part 16 that can be used to adjust the height of the tension wheel 151. Two lifting shafts 15 are provided and are symmetrically distributed with the tension wheel 151 as the center.

[0020] A receiving roller 22 rotatably connected to the inside of the side plate is arranged below the cutting roller 21, a lower roller 23 rotatably connected to the inside of the side plate is arranged on the side of the cutting roller 21 close to the tension wheel 151, and an upper roller 24 slidably connected to the inside of the side plate is arranged above the lower roller 23.

[0021] Two sliding seats 12 are provided and are symmetrically distributed with the workbench 11 as the center. A magnetic ring plate 145 is fixedly connected to the side of the annular plate 142 away from the sliding seat 12. A curved rubber block is fixedly connected to the side of the pressure plate 144 away from the hollow sleeve rod 141. Three pressure plates 144 are provided and distributed in a circular array with the hollow sleeve rod 141 as the center.

[0022] The tension adjusting member 16 includes a rotating rod 161, the middle part of which is rotatably connected to the side of the sliding seat 12 away from the rotating shaft 13, and the end of the rotating rod 161 close to the cutting blade 211 is fixedly connected to a linkage frame 162, and the internal connection of the linkage frame 162 adopts an arc angle design, and the side of the sliding seat 12 close to the rotating rod 161 is fixedly connected to a limiting block 163, and the limiting block 163 is slidably connected to an L-shaped rod 164, and the top of the L-shaped rod 164 is fixedly connected to the limiting frame 165.

[0023] The interior of the limiting frame 165 is designed to be arc-shaped, and the inner surface of the limiting frame 165 is in contact with the outer surface of the rotating rod 161 , and the interior of the linkage frame 162 is in contact with the circumferential outer surface of the lifting shaft rod 15 .

[0024] A notch is provided inside the sliding seat 12, and the outer end of the L-shaped rod 164 away from the limit frame 165 passes through the sliding seat 12 and is fixedly connected to the connecting plate 17. A long rod 171 is fixedly connected to the side of the connecting plate 17 away from the sliding seat 12. The long rod 171 is rotatably connected to the positioning wheel 172 through a ball bearing arranged on the outer surface of its circumference. A short rod 173 is fixedly connected to the side of the connecting plate 17 close to the long rod 171. The long rod 171 and the short rod 173 are in the same horizontal plane, and the long rod 171 and the short rod 173 are symmetrically distributed with the rotating shaft 13 as the center.

[0025] The upper surface of the workbench 11 is fixedly connected with a bracket 111, and an arc groove is opened on the upper surface of the bracket 111, and the inner wall of the arc groove fits with the outer surface of the positioning wheel 172. The outer end of the positioning wheel 172 away from the connecting plate 17 adopts an arc surface design, and the outer end of the short rod 173 away from the connecting plate 17 adopts a small arc surface design.

[0026] The process of loading the aluminum foil roll: In actual application, in the initial state, the slide rail groove is controlled by the driving base on the side of the workbench 11, and the two sliding seats 12 sliding inside it are moved to the side away from the bracket 111 at the same time, that is, the distance between the two sliding seats 12 increases, and the tensioner 14, the tension adjustment member 16 and the rotating shaft 13 move outwards together. At this time, the positioning wheel 172 is in the upper position within its movable range along with the connecting plate 17 and the L-shaped rod 164. The aluminum foil roll is moved from the top to the top of the feeding part 1 by using external lifting equipment, and the aluminum foil roll is vertically lowered from the middle of the two sliding seats 12. When the lower surface of the aluminum foil roll contacts the outer surface of the two positioning wheels 172, it slowly moves down until the central axis of the aluminum foil roll is roughly in the same position as the central axis of the rotating shaft 13.

[0027] When the aluminum foil roll moves downward, the lower surface of the aluminum foil roll contacts the outer surface of the positioning wheel 172. After the aluminum foil roll contacts the positioning wheel 172, it drives the connecting plate 17, the L-shaped rod 164 and the limit frame 165 (under the restriction of the limit block 163) to move vertically downward (the outer surface of the positioning wheel 172 always fits the outer surface of the aluminum foil roll). In this process, the rotating rod 161 drives the linkage frame 162 to tilt upward by using the lever principle, and the tension wheel 151 and the lifting shaft rod 15 are affected by the linkage frame 162 and move vertically upward on the outer surface of the guide rod.

[0028] When the central axis of the aluminum foil roll is roughly in the same position as the central axis of the rotating shaft 13, the sliding seats 12 on both sides are driven to move inward at the same time by the slide rail inside the workbench 11, and the distance between the two sliding seats 12 gradually decreases. During the movement, the magnetic ring plates 145 on both sides approach each other until they are attracted to each other. As the sliding seat 12 continues to move, the hollow sleeve rod 141 and the magnetic ring plate 145 move toward the annular plate 142 on the outer surface of the rotating shaft 13 at the same time. Since the end of the pressure plate 144 away from the magnetic ring plate 145 is slidably connected to the inside of the annular plate 142, and the pressure plate 144 is parallel to the rotating shaft 13, when the hollow sleeve rod 141 slides toward the annular plate 142, the pressure plate 144 is expanded to the outside through the displacement groove inside the annular plate 142 under the action of the connecting rod 143.

[0029] The outer surface of the pressing plate 144 away from the hollow sleeve rod 141 is fixedly connected with a curved rubber block. As the three pressing plates 144 are simultaneously expanded outward, their outer surfaces will fit with the inner surface of the roll of the aluminum foil roll. When the curved rubber block is elastically deformed, the rotating shaft 13 is completely consistent with the central axis of the aluminum foil roll, and the aluminum foil roll is also stably placed by the expansion member 14. At this time, the pressing plate 144 can no longer be expanded outward, the sliding seat 12 remains in this position, stops moving, and the external lifting equipment is also withdrawn.

[0030] When the diameter of the aluminum foil roll is the maximum diameter adapted by the expansion member 14 and the tension adjustment member 16, the aluminum foil roll will press the positioning wheel 172 to move downward. At this time, the bracket 111 can avoid the positioning wheel 172 and the long rod 171 being damaged due to impact.

[0031] During the process of the sliding seat 12 moving toward each other, the long rod 171 on one side and the short rod 173 on the other side approach each other, and the outer surface of the long rod 171 is rotatably connected to the positioning wheel 172. The length of the long rod 171 in the same group is less than the length of the inner surface of the circumference of the positioning wheel 172. The outer end of the short rod 173 adopts an arc surface with a small diameter, and the outer surface of the positioning wheel 172 on the same side away from the connecting plate 17 also adopts an arc surface design. When the long rod 171 and the short rod 173 are close to each other, the short rod 173 can smoothly enter the interior of the positioning wheel 172 to form a whole, thereby improving stability.

[0032] The process of cutting the aluminum foil roll: After the aluminum foil roll is loaded, it is unpacked, and the starting end of the aluminum foil is passed over the tension wheel 151, passed between the upper roller 24 and the lower roller 23, passed around the upper surface of the cutting roller 21 and fixed on the outer surface of the receiving roller 22. When the aluminum foil passes through the cutting roller 21, its outer surface is penetrated by the cutting blade 211 and cut into multiple sections. After the preparation is completed, the driving device inside the sliding seat 12 is started to drive the rotating shaft 13 to rotate, and the annular plate 142 mounted on the outer surface of the rotating shaft 13 rotates with it, and the aluminum foil roll also rotates with it through the expansion piece 14. In this process, the receiving roller 22 also rotates to collect the aluminum foil after cutting.

[0033] Initially, the outer diameter of the aluminum foil roll is relatively large, and the length of the aluminum foil output after the rotating shaft 13 rotates one circle is relatively long. In order to prevent the aluminum foil from wrinkling or deflecting, the tension needs to be increased. As the cutting roller 21 and the receiving roller 22 are continuously separated and collected, the raw materials of the aluminum foil roll are continuously output, and the outer diameter of the aluminum foil roll gradually decreases, that is, the length of the aluminum foil output after the rotating shaft 13 rotates one circle becomes shorter. At this time, in order to prevent the aluminum foil from being deformed or broken due to excessive tensile force, the tension of the aluminum foil needs to be reduced.

[0034] In the initial state, the positioning wheel 172 is at the bottom of the aluminum foil roll and fits tightly with the circumferential lower surface of the aluminum foil roll. The inner surface of the linkage frame 162 at the outer end of the rotating rod 161 fits with the circumferential outer surface of the tension wheel 151. Since the tension wheel 151 has a certain weight, the outer end of the lifting shaft 15 is inside the linkage frame 162, and the center of gravity of the tension wheel 151 is squeezed inside the linkage frame 162. The middle position of the rotating rod 161 is rotatably connected to the outer side of the sliding seat 12, acting as a fulcrum, which will drive the other end of the rotating rod 161 to drive the limit frame 165 to pry upward, giving the L-shaped rod 164 an upward force inside the limit block 163, intensifying the fit of the positioning wheel 172 below the L-shaped rod 164 with the outer surface of the aluminum foil roll, and increasing the friction between the positioning wheel 172 and the outer surface of the aluminum foil roll.

[0035] As the aluminum foil is continuously unwound, the diameter of the aluminum foil roll gradually decreases, and the tension and position state of the outermost layer of aluminum foil are also constantly changing. The positioning wheel 172 can adapt to such changes by continuously fitting with the outer surface of the aluminum foil roll and continuously applying pressure and friction, and always keep the outermost layer of aluminum foil under restraint. Especially when the unwinding speed is fast or the aluminum foil roll is loosely wound, the positioning wheel 172 can prevent the outermost layer of aluminum foil from sliding off due to centrifugal force or uneven internal tension, thereby improving stability and ensuring cutting quality.

[0036] As the number of rotations of the rotating shaft 13 increases, the length of the aluminum foil roll output per rotation gradually decreases, and the tension needs to be reduced to avoid stretching deformation, breakage, and the like. The outer diameter of the aluminum foil roll begins to gradually decrease, and the tension wheel 151 always has a downward gravity. With the middle of the rotating rod 161 as a fulcrum, the rotating rod 161 is affected by the gravity of the tension wheel 151, and the circumferential outer surface of the positioning wheel 172 is always in contact with the lower outer surface of the aluminum foil roll through the L-shaped rod 164. After the outer diameter of the aluminum foil roll decreases, the positioning wheel 172 gradually moves vertically upward, and the L-shaped rod 164 and the limit frame 165 move vertically upward together. The interior of the limit frame 165 adopts a curved surface design, and the outer surface of the rotating rod 161 can always fit the interior of the limit frame 165 and maintain a smooth state for movement. After the limiting frame 165 moves upward, the linkage frame 162 at the other end of the rotating rod 161 will rotate downward accordingly, and the lifting shaft rod 15 that fits inside the linkage frame 162 will also move vertically downward.

[0037] During this process, the wrapping angle between the tension wheel 151 and the aluminum foil bag decreases, the friction force decreases, and the tension also decreases accordingly. The path of the aluminum foil around the tension wheel 151 to reach the upper roller 24 and the lower roller 23 becomes shorter, which can match the gradually decreasing output length of the aluminum foil as the shaft 13 rotates, reducing the tension of the aluminum foil and avoiding the breakage of the aluminum foil due to excessive tension.

[0038] As the rotating shaft 13 rotates continuously at a uniform speed, the distance of the output aluminum foil per rotation will become shorter and shorter. The positioning wheel 172 is affected by the gravity of the tension wheel 151 and is always in contact with the outer surface of the aluminum foil roll. The outer diameter of the aluminum foil roll gradually decreases, the height of the positioning wheel 172 gradually increases, the height of the tension wheel 151 and the lifting shaft 15 gradually decreases, and the wrap angle between the tension wheel 151 and the external aluminum foil gradually decreases. The path of the aluminum foil from the outer surface of the aluminum foil roll to the lower roller 23 gradually becomes flatter, and the path distance of the aluminum foil from the rotating shaft 13 to the cutting roller 21 gradually becomes shorter, which is adapted to the tension required for the aluminum foil roll with a gradually decreasing outer diameter.

[0039] The process of unloading the aluminum foil roll: When all the aluminum foil rolls are cut, the positioning wheel 172, the L-shaped rod 164, and the limit frame 165 are slidably connected to the inside of the limit block 163, and are all at the highest point within their range of movement; accordingly, the tension wheel 151 is slidably connected to the outer surface of the guide rod through the lifting shaft rod 15, and is at the lowest point within its range of movement. At this time, the rotating rod 161 is lower near the linkage frame 162 and is in a tilted state.

[0040] By driving the base to control the sliding seats 12 on both sides to move to the side away from the bracket 111, the tension adjusting member 16, the expansion member 14 and the rotating shaft 13 will move synchronously. When the expansion members 14 on both sides follow the rotating shaft 13 and move away from each other, the magnetic ring plate 145 at the outer end thereof still maintains the magnetic attraction, driving the hollow sleeve rod 141 to remain stationary, and relative displacement occurs between the rotating shaft 13 and the ring plate 142. The distance between the magnetic ring plate 145 and the ring plate 142 increases, which will drive the pressing plate 144 to move closer to the circumferential outer surface of the hollow sleeve rod 141 under the action of the connecting rod 143. The pressing plate 144 completes the contraction and reset action under the magnetic attraction of the magnetic ring plate 145 and the gravity of the remaining aluminum foil roll.

[0041] At this time, the inner diameter of the aluminum foil roll is larger than the diameter surrounded by the three pressure plates 144 in the tensioning member 14. Since the positioning wheel 172 is always affected by the tension wheel 151, the upward force is applied to it, which drives the remaining aluminum foil roll to move upward, and the rotating shaft 13 moves toward the sliding seat 12. After the rotating shaft 13 is pulled out, the aluminum foil roll is located above the two positioning wheels 172, and its circumferential outer surface is tangent to the circumferential outer surfaces of the two positioning wheels 172. After the remaining aluminum foil roll is removed, a new aluminum foil roll is put in again by the external lifting mechanical arm and the cutting blade 211 is used to continue cutting.

[0042] In summary, the aluminum foil roll feeding and cutting process has the following advantages: Advantage 1: When loading, the sliding seats 12 on both sides are close to each other, and the tightening members 14 on both sides are also close to each other. After the two magnetic ring plates 145 are tightly fitted, they can drive the pressure plate 144 to expand outward, and fix the external aluminum foil roll from the inside, so that the central axis of the aluminum foil roll is consistent with the central axis of the rotating shaft 13, ensuring the stability of transportation, avoiding the situation where different friction forces are caused by inconsistent distances between different parts of the aluminum foil roll and the rotating shaft 13, so that the tension of the aluminum foil is uniform when it is unrolled from the roll, and the cutting accuracy is improved. When the rotating shaft 13 rotates, the pressure plate 144 will also move outward due to the centrifugal force, which intensifies the fixation of the aluminum foil roll.

[0043] Advantage 2: When unloading, the sliding seats 12 on both sides move away from each other. When the tensioning parts 14 move away from each other, the magnetic ring plates 145 inside them attract each other, and the magnetic ring plates 145 drive the hollow sleeve rod 141 and the annular plate 142 to move relative to each other. Under the cooperation of the gravity of the aluminum foil roll, the contraction action of the tensioning part 14 is completed, which makes it easy to take out the used aluminum foil roll and prepare for the next loading.

[0044] Advantage 3: When cutting aluminum foil rolls, in order to ensure the continuity of supply and reduce the frequency of replacement, aluminum foil rolls with more layers will be used. As the same roll of material is continuously rotated and conveyed, the length of the aluminum foil output by the feed roller will gradually shorten with each rotation of the feed roller, resulting in excessive tension, which will cause the thinner aluminum foil to break. The tension adjustment member 16 can change the required tension in real time according to the remaining thickness of the aluminum foil roll. By adjusting the position of the tension wheel 151 up and down, the tension and conveying path of the aluminum foil can be optimized, and the cutting process can be carried out more smoothly, reducing the number of cutting interruptions caused by aluminum foil wrinkles and offsets, thereby increasing the output per unit time.

[0045] Advantage 4: Before loading, the positioning wheel 172 is raised by the tension wheel 151 using the lever principle. When the aluminum foil roll is placed, the positioning wheel 172 is pressed to move vertically downward. During this process, the circumferential outer surface of the positioning wheel 172 is always in contact with the circumferential outer surface of the aluminum foil roll. The position of the tension wheel 151 can be confirmed during loading, and the required tension can be adjusted without manual adjustment, thereby achieving continuous production cutting.

[0046] Advantage 5: The expansion member 14 and the tension adjusting member 16 can be applied to the cutting of aluminum foil coils with different inner diameters and different numbers of layers within a certain range, thereby improving the versatility of the product.

[0047] Advantage 6. Under the gravity of the tension wheel 151, the outer surface of the positioning wheel 172 always fits with the outer surface of the lower side of the aluminum foil roll. As the aluminum foil is continuously released, the diameter of the aluminum foil roll gradually decreases, and the tension and position of the outermost layer of aluminum foil are also constantly changing. The positioning wheel 172 can adapt to such changes by continuously fitting with the outer surface of the aluminum foil roll and continuously applying pressure and friction, and always keep the outermost layer of aluminum foil under control. Especially when the unwinding speed is fast or the aluminum foil roll is loosely wound, the positioning wheel 172 can prevent the outermost layer of aluminum foil from sliding off due to centrifugal force or uneven internal tension, thereby improving stability and ensuring cutting quality.
