Description

Technical Field

[0001] This manual relates to the field of aerospace thermal control technology, specifically to an automated folding device for aluminum foil bellows sheets. Background Technology

[0002] With the rapid advancement of aerospace technology, spacecraft in low Earth orbit are facing increasingly complex challenges from the space environment. These spacecraft interact with surrounding plasma and solar radiation, resulting in uneven charge distribution on their surfaces. As a major component of the satellite's surface, the multilayer thermal insulation assembly's accumulated charged particles can pose a serious threat to the safe and stable operation of the spacecraft, and may even lead to the breakdown of the multilayer thermal insulation assembly or its internal components. To mitigate the risk of electrostatic accumulation, multilayer thermal insulation assemblies typically control their potential through surface conductive treatment and grounding of the conductive layer.

[0003] In multi-layer thermal insulation components, grounding is achieved through accordion blade grounding: aluminum foil is cut into 20mm wide strips and folded into an accordion-like structure, with the number of layers matching the number of unit layers in the multi-layer thermal insulation component. The folded accordion blades form squares with sides of 20mm. Each accordion blade is embedded between double-sided aluminized polyester films and riveted to the accordion blades as a whole using grounding rivets.

[0004] Currently, the production of aluminum foil accordion sheets at home and abroad mainly relies on manual cutting and folding, which leads to problems such as low production efficiency, poor consistency and high cost, and cannot meet the quantitative and quality requirements of aerospace technology development for aluminum foil accordion sheets.

[0005] Therefore, developing automated folding equipment for aluminum foil bellows sheets to achieve mechanized production is of great practical significance and has broad market potential for improving production efficiency and meeting the needs of mass production of high-precision satellites.

[0036] Furthermore, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the described aspects can be practiced without these specific details.

[0037] With the rapid development of aerospace technology, low Earth orbit has become a crucial region for numerous spacecraft to explore and operate in. However, the increasingly complex space environment in this region presents many severe challenges to the stable operation of spacecraft.

[0038] Spacecraft in low Earth orbit constantly interact with the complex space environment, among which plasma and solar radiation are particularly critical. Plasma consists of a large number of charged particles, while solar radiation carries high-energy particles and electromagnetic radiation. When a spacecraft is in such an environment, its surface inevitably interacts with these charged particles and radiation, resulting in an uneven charge distribution on the spacecraft's surface. This uneven charge distribution is like a "time bomb" hidden inside the spacecraft, which could trigger a series of serious problems at any time.

[0039] Multilayer thermal insulation components, as a major component of a satellite's surface, play a crucial role in its thermal protection and structural stability. However, due to their large surface area and the complex electrical environment of space, they are highly susceptible to accumulating charged particles. When the accumulated charge reaches a certain level, it poses a serious threat to the safe and stable operation of the spacecraft. For example, excessive static electricity accumulation may cause breakdown of the multilayer thermal insulation components themselves or their internal precision components. Once breakdown occurs, it will directly damage the satellite's thermal protection system, affect the satellite's normal functions, and may even lead to the failure of the entire satellite mission, resulting in huge economic losses and a waste of scientific research resources.

[0040] To effectively reduce the risk of electrostatic accumulation in multilayer thermal insulation components and ensure the safe operation of spacecraft, surface conductive treatment and grounding of the conductive layers are commonly used to control their potential. Among the grounding methods for multilayer thermal insulation components, accordion blade grounding is a common and effective approach. Specifically, aluminum foil is cut into strips 20mm wide and then folded into an accordion-like structure. The number of layers in this accordion structure needs to be precisely matched to the number of unit layers in the multilayer thermal insulation component, resulting in a square accordion blade with a side length of 20mm. Each accordion blade is then carefully embedded between double-sided aluminized polyester film and securely riveted to the accordion blade using grounding rivets, forming a complete conductive path and thus achieving grounding and effectively dissipating electrostatic charges.

[0041] However, the current state of aluminum foil accordion sheet production both domestically and internationally is far from optimistic. The production method, primarily reliant on manual cutting and folding, has numerous drawbacks. Manual operation is not only inefficient, making it difficult to meet the mass production demands of aerospace technology; moreover, due to the limitations of manual operation, product consistency is difficult to guarantee. Different batches, and even products from the same batch, may exhibit significant differences in dimensional accuracy and folding quality, which undoubtedly affects the overall performance and reliability of multi-layer thermal insulation components. Furthermore, manual production requires substantial labor costs, resulting in high production costs and further limiting the large-scale production and widespread application of aluminum foil accordion sheets.

[0042] With the continuous advancement of aerospace technology, the mass production of high-precision satellites has become a development trend, placing higher demands on both the quantity and quality of aluminum foil accordion sheets. Therefore, developing an automated folding device for aluminum foil accordion sheets to achieve mechanized and large-scale production has become a critical issue urgently needing to be addressed in the aerospace field. The development of this equipment will not only significantly improve production efficiency and meet the needs of large-scale spacecraft production, but also effectively improve product consistency and quality stability. This has significant practical implications and broad market potential for ensuring the safe and stable operation of spacecraft and promoting the continuous development of aerospace technology.

[0043] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0044] like Figures 1-8 As shown, an automated folding device for aluminum foil accordion sheets includes a feeding mechanism 1, a folding and cutting mechanism, and a storage mechanism.

[0045] The feeding mechanism 1 is used to transport the aluminum foil material 2 to the stacking and cutting mechanism;

[0046] The folding and cutting mechanism includes an indentation device 6, a cutting device 7, and a folding device 8. The indentation device 6 includes an upper pressure plate 6-1, a lower pressure plate 6-4, an upper groove plate 6-2, a lower groove plate 6-3, an indentation mold 6-5, and a pressure applying mechanism 6-6. The pressure applying mechanism 6-6 is connected to the upper pressure plate 6-1 and / or the lower pressure plate 6-4 to adjust the distance between the upper pressure plate 6-1 and the lower pressure plate 6-4. The indentation mold 6-5 is installed on the upper pressure plate 6-1 and the lower pressure plate 6-4. When the upper pressure plate 6-1 and the lower pressure plate 6-4 move relative to each other, the indentation mold 6-5 passes through the slots on the upper groove plate 6-2 and the lower groove plate 6-3 to indent the aluminum foil material 2 between the upper groove plate 6-2 and the lower groove plate 6-3. The cutting device 7 cuts the indented aluminum foil material 2, and the folding device 8 folds the cut aluminum foil material 2.

[0047] The storage mechanism stores the compressed and folded aluminum foil material 2.

[0048] The feeding mechanism 1 enables automatic and continuous conveying of aluminum foil material 2, changing the traditional manual feeding method, improving the efficiency and stability of feeding, providing a reliable material supply guarantee for subsequent folding and cutting processes, and reducing production failures and material waste caused by unstable manual feeding.

[0049] The upper pressure plate 6-1 and lower pressure plate 6-4 are each equipped with a detachable indentation mold 6-5. With the cooperation of the sensing device and the vertical movement of the pressure applying mechanism 6-6, when the flat aluminum foil material is conveyed between the upper slot plate 6-2 and the lower slot plate 6-3 to the end of the indentation device 6, the infrared sensing device at the end detects that the flat aluminum foil material has been conveyed to a certain length. The automatic control system then controls the feeding mechanism 1 to stop feeding, and the pressure applying mechanism 6-6 controls the movement of the upper pressure plate 6-1 and the lower pressure plate 6-4. The indentation mold 6-5 passes through the upper slot plate 6-2 and the lower slot plate 6-3 and indents the aluminum foil material, creating specific folding marks on the aluminum foil, preparing it for subsequent folding processes. This precise indentation of the required marks on the aluminum foil ensures the accuracy of the folding position, provides clear markings for subsequent folding processes, and results in a neat and precise shape and size of the folded accordion sheet, improving product quality consistency.

[0050] The cutting device 7 precisely cuts the aluminum foil material 2, ensuring that the length of the cut aluminum foil gusset sheet meets the design requirements and improving the dimensional accuracy of the product. The folding device 8 squeezes and folds the cut aluminum foil material 2, and the folded aluminum foil material 2 falls into the storage mechanism.

[0051] In some embodiments, the cutting device 7 includes a CNC cutting track 7-2 and a cutting blade 7-1, the cutting blade 7-1 being mounted on the CNC cutting track 7-2 and moving along the CNC cutting track 7-2 to cut the aluminum foil material 2. The cutting device 7 also includes a counting sensor; when the counting sensor detects that the indentations on the aluminum foil material 2 have reached a specified number, the cutting device 7 cuts the aluminum foil material 2.

[0052] After the aluminum foil material 2 is creasing by the creasing device 6, it is fed into the area of ​​the cutting device 7. At this point, the cutting device 7 does not immediately perform the cutting operation. Instead, it relies on other supporting sensing devices (such as infrared sensors) and counting sensors to accurately determine the cutting timing. For example, during the feeding process, the counting sensor continuously records the number of folds formed by the creasing on the aluminum foil. When a set number of folds (e.g., the 16th) has passed, it means that the required cutting position has been reached. At this time, the counting sensor sends a signal back to the digital control system. After receiving the signal, the digital control system precisely controls the cutting blade 7-1 to move along the CNC cutting track 7-2 according to preset parameters such as the cutting length. The CNC cutting track 7-2 provides a precise movement path for the cutting blade 7-1. Driven by a motor or other power device, it can make the cutting blade 7-1 move linearly in specific directions, such as the horizontal direction, according to a predetermined program and instructions, thereby achieving accurate cutting of the aluminum foil material 2. During the cutting process, the cutting blade 7-1 moves downward in a direction perpendicular to the surface of the aluminum foil material 2, using its sharp blade to cut the aluminum foil material 2.

[0053] The coordination between the CNC cutting track 7-2 and the digital control system enables the cutting blade 7-1 to move strictly according to preset parameters and paths, thereby achieving high-precision cutting of the aluminum foil material 2. This ensures that the length of the cut aluminum foil gusseted sheet meets design requirements, with high dimensional accuracy, effectively avoiding dimensional deviations that may occur with manual cutting, and guaranteeing the stability and consistency of product quality. For example, in the production of high-precision satellites with extremely strict dimensional requirements, this precise cutting ensures perfect matching of various parts of multi-layer thermal insulation components, improving the overall performance of the satellite.

[0054] The entire cutting process relies on the coordinated operation of sensing devices, counting sensors, and a digital control system, achieving a high degree of automation. No manual operation of the cutting blade 7-1 is required, reducing human error, which not only improves production efficiency but also reduces the labor intensity of workers. Workers only need to perform some basic setup and monitoring tasks before starting the equipment, significantly saving labor costs.

[0055] The rapid movement of the CNC cutting track 7-2 and precise cutting control enable the cutting process to be completed in a short time. Compared with traditional manual cutting methods, the cutting time for each aluminum foil material 2 is greatly shortened, thereby improving the efficiency of the entire production process. This meets the demand for mass production of aluminum foil bellows sheets in aerospace technology development and adapts to the pace of high-precision satellite mass production.

[0056] Since the cutting process is completed automatically by the equipment, workers do not need to directly contact the cutting blade 7-1, effectively reducing the risk of cutting injuries caused by improper operation and ensuring the safety and health of workers. At the same time, it also avoids equipment damage and other safety accidents that may result from human error, improving the safety of the production process.

[0057] like Figure 1 and Figures 5-7 As shown, in some embodiments, the folding device 8 includes a folding box groove 8-2, a front end baffle 8-3, and a rear end baffle 8-1. The front end baffle 8-3 and the rear end baffle 8-1 are respectively disposed on the front and rear sides of the folding box groove 8-2. The rear end baffle 8-1 is an automatically rotating baffle. The front end baffle 8-3 is provided with a telescopic member. The telescopic member drives the front end baffle 8-3 to slide relative to the folding box groove 8-2, thereby reducing the distance between the front end baffle 8-3 and the rear end baffle 8-1, thereby compressing and folding the aluminum foil material 2 in the folding box groove 8-2.

[0058] The folding device 8 is responsible for compressing and folding the cut aluminum foil material 2 to form a regular accordion shape. The folding device 8 mainly consists of a folding box groove 8-2, a front baffle 8-3, and a rear baffle 8-1. The front baffle 8-3 and the rear baffle 8-1 are respectively located on the front and rear sides of the folding box groove 8-2. The rear baffle 8-1 is designed as an automatic rotating baffle, and the front baffle 8-3 is equipped with a telescopic component.

[0059] After the aluminum foil material 2 is cut by the cutting device 7, it slides into the folding box slot 8-2 along a certain path. At this time, the front end of the aluminum foil material 2 will reach the rear end baffle 8-1 (automatic rotating baffle) and stop sliding forward, while the rear end continues to stack forward. During this process, the telescopic component begins to play its role. The telescopic component is usually composed of parts with telescopic capabilities (such as telescopic springs, electric telescopic rods, etc.), which drives the front end baffle 8-3 to slide relative to the folding box slot 8-2. As the front end baffle 8-3 slides, the distance between the front end baffle 8-3 and the rear end baffle 8-1 gradually decreases. This is like a gradually tightening "clamp" that squeezes the aluminum foil material 2 in the folding box slot 8-2. During the squeezing process, the aluminum foil material 2 is folded according to the marks pressed out by the previous indentation device 6, eventually forming a regular accordion shape. After the squeezing and folding operation is completed, the automatic rotating baffle (rear end baffle 8-1) will rotate. For example, it will rotate downwards to open, making way for the folded aluminum foil accordion to slide out, allowing the folded aluminum foil accordion to slide smoothly into the storage mechanism through the curved track, completing the entire folding and storage process.

[0060] Through the telescopic sliding of the front baffle 8-3 and its coordinated pressing with the rear baffle 8-1, the aluminum foil material 2 can be folded precisely according to the pre-pressed marks. This precise pressing and folding method results in a very regular shape for the final accordion-like sheet, with each layer maintaining a high degree of consistency in folding angle and position. This effectively improves product quality and meets the stringent requirements of high-precision satellite production for the shape of aluminum foil accordion-like sheets in multi-layer thermal insulation components.

[0061] The rear baffle 8-1 adopts an automatic rotating baffle design, and the front baffle 8-3 is automatically slidable by a telescopic component, realizing the automation of the folding process. Manual folding of the aluminum foil material 2 is eliminated, reducing the impact of human factors on folding quality and significantly improving production efficiency. Workers only need to monitor the overall equipment and set basic parameters, reducing their labor intensity and meeting the needs of high-precision satellite mass production.

[0062] like Figure 1 and Figure 7 As shown, in some embodiments, the folding device 8 further includes an arc-shaped slide rail connected to the rear end of the folding box slot 8-2. When the front end baffle 8-3 is rotated open, the aluminum foil material 2 in the folding box slot 8-2 slides down into the storage mechanism via the arc-shaped slide rail. The arc-shaped slide rail is tightly connected to the rear end of the folding box slot 8-2 and is arc-shaped. This design is to make the aluminum foil accordion sheet slide down more smoothly, reducing friction and jamming. When the front end baffle 8-3 is opened, the aluminum foil accordion sheet in the folding box slot 8-2 will slide down naturally along the rear end of the folding box slot 8-2 to the arc-shaped slide rail due to its own gravity. The arc-shaped slide rail, with its smooth surface and suitable curvature, guides the aluminum foil accordion sheet to slide down at a relatively stable and controllable speed, and finally slides accurately into the storage mechanism, completing the transfer process from the folding device 8 to the storage mechanism.

[0063] The curved design of the slide rail ensures that the aluminum foil accordion slide experiences more uniform resistance during its descent, avoiding jamming and bumping caused by sudden changes in plane or right-angle turns. The aluminum foil accordion slides smoothly from the folding box slot 8-2 to the storage mechanism, reducing the risk of damage from collisions and friction during transfer, ensuring product integrity, and improving product quality. For example, in the production of satellite thermal insulation multilayer components with high surface quality requirements, a smooth transfer process effectively avoids scratches and wrinkles on the aluminum foil surface. The curved slide rail provides a continuous, automatic transfer channel for the aluminum foil accordion slide, allowing for the rapid and accurate delivery of folded products to the storage mechanism without manual intervention. This significantly shortens the time interval between product folding and storage, improving the continuity and efficiency of the entire production process. In high-precision satellite mass production, the ability to quickly transfer and store products helps meet the demands of large-scale production and increase production capacity.

[0064] like Figure 1 and Figure 4 As shown, in some embodiments, the folding and cutting mechanism further includes a pressing device 4 and a protective cover 5. The pressing device 4 is disposed in front of the inlet of the indentation device 6. The pressing device 4 includes an upper pressing plate and a lower pressing plate with an adjustable relative distance. The protective cover 5 is disposed outside the folding and cutting mechanism.

[0065] The pressing device 4 is located in front of the inlet of the creasing device 6 and consists of an upper pressure plate and a lower pressure plate with an adjustable relative distance. This layout ensures that the aluminum foil material 2 is pressed before entering the creasing process. The adjustability of the upper and lower pressure plates is its core design feature. The distance between them can be precisely controlled by a mechanical adjustment mechanism (such as a screw, slide rail, etc.) or a power drive device (such as a cylinder, electric push rod, etc.). When the aluminum foil material 2 is conveyed to the pressing device 4, the upper and lower pressure plates adjust their distance according to preset parameters to apply uniform pressure to the material. The pressure can be controlled by adjusting the parameters of the mechanism or power device to ensure that the aluminum foil material 2 will not deform or be damaged due to excessive pressure, nor will it fail to achieve the desired pressing effect due to insufficient pressure. The pressed aluminum foil material 2 has a smooth surface and uniform internal stress distribution, providing a stable foundation for the subsequent creasing process. The compressed aluminum foil material 2 smoothly enters the indentation device 6, which processes the material according to preset indentation parameters (such as indentation depth, width, and spacing). Since the material has passed through the compression device 4 to eliminate internal stress and surface unevenness, problems such as displacement, breakage, or unclear indentation are less likely to occur during the indentation process, thereby improving the indentation quality and stability.

[0066] The protective cover 5 is located outside the folding and cutting mechanism and adopts a fully enclosed or semi-enclosed design to completely cover the cutting area, folding area, and moving parts. During the operation of the folding and cutting mechanism, the protective cover 5 completely isolates the operator from the cutting blade 7-1, folding parts, and other dangerous areas through physical isolation.

[0067] like Figure 1 and Figures 3-4 As shown, in some embodiments, the indentation mold 6-5 includes several upper round-headed rack molds and several lower round-headed rack molds, which are connected to the upper pressure plate 6-1 and the lower pressure plate 6-4, respectively. The indentation mold 6-5 is composed of several upper round-headed rack molds and several lower round-headed rack molds. The upper round-headed rack molds are connected to the upper pressure plate 6-1, and the lower round-headed rack molds are connected to the lower pressure plate 6-4. This connection method typically employs stable mechanical connections such as bolt fixing or slot nesting to ensure that during equipment operation, the upper and lower round-headed rack molds maintain a relatively fixed positional relationship with the upper and lower pressure plates 6-4, and will not shift due to vibration or external forces.

[0068] Before the equipment is started, the relative positions of the upper and lower round-headed rack molds are precisely adjusted according to the preset indentation parameters (such as the spacing, depth, and width of the indentations) so that they correspond accurately in the vertical direction, thereby ensuring that uniform and accurate pressure is applied to the aluminum foil material 2 during the indentation process.

[0069] When the aluminum foil material 2 is conveyed to the indentation station, the upper pressure plate 6-1 moves downward under the drive of the power system (such as a hydraulic cylinder, pneumatic cylinder, or electric push rod), causing the upper round-headed rack mold to move downward synchronously. At the same time, the lower pressure plate 6-4 remains in a fixed position (or moves towards the lower pressure plate 6-4), and the lower round-headed rack mold is also stationary.

[0070] As the upper pressure plate 6-1 continues to press down, the upper round-headed rack mold gradually approaches the lower round-headed rack mold. When both come into contact with the aluminum foil material 2, pressure is applied to the aluminum foil. Due to the rack shape design of the upper and lower round-headed rack molds, they will form a series of regularly arranged indentations on the surface of the aluminum foil material 2.

[0071] The rounded head design allows for a more even distribution of pressure on the aluminum foil surface during the indentation process, preventing the foil from cracking or undergoing unnecessary deformation due to excessive local pressure. Meanwhile, the shape and spacing of the toothed dies determine the shape and spacing of the indentations. By adjusting the relative positions of the upper and lower rounded toothed dies and the toothed dies' parameters, indentations of different specifications and requirements can be achieved.

[0072] Once the upper pressure plate 6-1 reaches the preset indentation depth, the power system stops pressing down and maintains pressure for a period of time to ensure that the indentation is fully formed. Then, the upper pressure plate 6-1 moves upward under the reverse drive of the power system, causing the upper round-headed toothed mold to leave the aluminum foil material 2, completing one indentation operation.

[0073] By combining several upper round-headed rack dies and several lower round-headed rack dies, multiple indentations can be formed simultaneously in a single indentation operation, greatly improving indentation efficiency. Compared with the traditional single-tooth indentation method, this reduces the number of indentations and equipment running time, thereby shortening the overall production cycle and improving production efficiency.

[0074] like Figures 1-2 As shown, in some embodiments, the feeding mechanism 1 includes a rotatable inner shaft 1-1 and a shaping device 3. The aluminum foil roll 1-2 is placed on the inner shaft 1-1, and a rotating pair structure is formed between the inner shaft 1-1 and the shaping device 3, so that the aluminum foil material 2 can be continuously shaped by the shaping device 3 and fed into the folding and cutting mechanism.

[0075] Aluminum foil roll 1-2 is mounted on a rotatable inner shaft 1-1. When the feeding program is started, the inner shaft 1-1 begins to rotate under the drive of a power source (such as a motor). The motor transmits power to the inner shaft 1-1 through a transmission device (such as a belt, gears, etc.), causing it to rotate at a set speed and direction. The rotation of the inner shaft 1-1 drives the aluminum foil roll 1-2 mounted on it to rotate synchronously, providing the basic power for the continuous feeding of aluminum foil material 2.

[0076] The shaping device 3 is a key part of the feeding mechanism 1, and it forms a rotating joint structure with the inner shaft 1-1. The rotating joint structure allows the inner shaft 1-1 to rotate freely under the constraint of the shaping device 3, while the shaping device 3 can also shape and guide the aluminum foil material 2.

[0077] The shaping device 3 typically has a specific shape and size that matches the width and thickness of the aluminum foil material 2. When the aluminum foil material 2 is unwound from the roll, it first comes into contact with the shaping device 3. The shaping device 3 uses the contours and friction of its surface to initially shape the aluminum foil material 2, keeping it flat and straight, and eliminating wrinkles and bends that occur during the winding process.

[0078] During the rotation of the inner shaft 1-1, the shaping device 3 remains relatively fixed (or can be finely adjusted within a certain range to accommodate aluminum foil materials 2 of different specifications). The aluminum foil material 2 passes through the shaping device 3 under the drive of the inner shaft 1-1. The shaping device 3 continuously applies a shaping effect to the aluminum foil material 2, ensuring that the material maintains good shape and dimensional accuracy before being fed into the folding and cutting mechanism.

[0079] As the inner shaft 1-1 rotates continuously, the aluminum foil material 2 unfolds from the material roll and, after being shaped by the shaping device 3, is fed into the folding and cutting mechanism. The feeding speed can be precisely controlled by adjusting the motor speed or the transmission ratio of the transmission device to meet the working rhythm requirements of the folding and cutting mechanism.

[0080] The shaping device 3 effectively eliminates wrinkles and bends in the aluminum foil material 2 during the winding process, resulting in a smooth and flat surface. This is crucial for the production of high-precision satellite thermal insulation multilayer components, as wrinkles and bends can affect the folding accuracy and thermal insulation performance of the aluminum foil gusset sheets. The shaping process ensures that each aluminum foil gusset sheet meets stringent quality requirements. The precise design and dimensional matching of the shaping device 3 ensure that the aluminum foil material 2 maintains the set width and thickness dimensions throughout the feeding process. Stable dimensional accuracy facilitates accurate processing of the material by the subsequent folding and cutting mechanism, improving the overall quality and consistency of the product.

[0081] The shaping device 3 is typically adjustable and can be adjusted according to aluminum foil materials 2 of different widths and thicknesses. This allows the feeding mechanism 1 to adapt to aluminum foil rolls 1-2 of various specifications, improving the versatility and flexibility of the equipment and meeting the production needs of different products.

[0082] like Figures 1-2 As shown, in some embodiments, the shaping device 3 includes an upper pressure roller 3-1 and a lower pressure roller 3-2, through which the aluminum foil material 2 passes. The shaping device 3 is composed of the upper pressure roller 3-1 and the lower pressure roller 3-2, which are arranged in parallel relative to each other. When the aluminum foil material 2 begins to enter the feeding process, it is guided to the gap position between the upper pressure roller 3-1 and the lower pressure roller 3-2. At this time, the upper pressure roller 3-1 and the lower pressure roller 3-2 are either stationary or in a state of rotational preparation synchronized with the feeding, depending on the control mode of the equipment. If it is stationary, at the moment the aluminum foil material 2 enters the gap, the pressure roller will start to rotate due to the propulsive force of the material and the friction of the roller surface; if it is set to rotate synchronously with the feeding, the aluminum foil material 2 can be received more smoothly.

[0083] There is a certain preload between the upper pressure roller 3-1 and the lower pressure roller 3-2. This preload can be adjusted by a spring, cylinder or hydraulic system. When the aluminum foil material 2 passes between the upper and lower pressure rollers 3-2, the preload will cause the upper pressure roller 3-1 to press down and the lower pressure roller 3-2 to push up, thereby applying uniform pressure to the aluminum foil material 2.

[0084] Under pressure, the aluminum foil material 2 undergoes plastic deformation. If the aluminum foil material 2 has wrinkles, bends, or unevenness during the winding process, the pressure will flatten these uneven parts. At the same time, the surfaces of the upper and lower pressure rollers 3-2 usually have a certain degree of roughness and texture, which can increase the friction between them and the aluminum foil material 2, ensuring that the aluminum foil material 2 will not slip or shift during the shaping process, further guaranteeing the shaping effect.

[0085] like Figure 1 and Figure 8 As shown, in some embodiments, the storage mechanism includes a storage box 9, which is disposed behind the folding and cutting mechanism. The storage box 9 is fixedly disposed behind the folding and cutting mechanism, and its position is precisely designed and adjusted to perfectly align with the discharge port of the folding and cutting mechanism. The storage box 9 has a certain volume and a suitable shape, which can be customized according to the size and folding method of the aluminum foil accordion sheets. When the aluminum foil accordion sheets enter the storage box 9 through the conveying channel, they are stacked inside the box in a certain arrangement. For example, a layered stacking method may be used, with a certain number of aluminum foil accordion sheets placed in each layer to ensure neat and orderly storage.

In particular, the method embodiments described later are relatively simple in description since they correspond to the system, and relevant parts can be referred to the descriptions in the system embodiments.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
