Description

Technical Field

[0001] This invention relates to the field of film winding and unwinding technology, and in particular to a hydrogen-isolated film winding device and unwinding method. Background Technology

[0002] In the continuous manufacturing process of high-temperature composite functional membranes such as carbon-based functional membranes and hydrogen separation membranes, the membrane material exhibits extremely high surface activity after sintering, making it prone to oxidation and degradation upon contact with oxygen, resulting in a decline in core properties such as conductivity and barrier properties. Hydrogen-isolated membrane winding devices are core equipment in the downstream section of such thin film production lines. These specialized winding devices can continuously maintain a hydrogen protective atmosphere within a sealed space, completely isolating external oxygen from intrusion, and completing the winding and collection of the membrane material. Their atmosphere protection capability and operational continuity directly determine the performance stability and production efficiency of the finished membrane.

[0003] Existing hydrogen-protected winding systems mostly employ an integrated sealed winding chamber structure, integrating multiple winding mechanisms into a single chamber. A protective atmosphere is created through overall hydrogen filling. Some solutions add multi-station turrets or side-mounted transition chambers to reduce downtime. However, existing solutions cannot achieve independent gas path isolation for individual winding stations. When changing rolls or unloading materials, the main chamber or connecting transition chamber must be opened, which can easily cause a large amount of hydrogen leakage and air infiltration, increasing both operational losses and the risk of membrane oxidation. When using a multi-stage winding arrangement, the gas paths between stations cannot be completely isolated. Changing rolls at a single station can easily interfere with the atmosphere stability of other stations, making it difficult to simultaneously achieve high production continuity and high hydrogen isolation reliability.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the general background of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] In view of at least one of the above technical problems, the present invention provides a hydrogen-isolated film winding device and a feeding method, which adopts an architecture that combines graded independent winding chambers with a sealed compartment structure to achieve single-compartment isolated winding and stable hydrogen-isolated winding throughout the process.

[0006] This invention provides a hydrogen-barrier membrane winding device, comprising: The sintering box, pressure roller chamber, transition cavity and grading and winding chamber are connected sequentially along the direction of membrane material travel; The top of the pressure roller chamber is provided with a hydrogen outlet, and the interior is provided with multiple sets of pressure roller assemblies for film roll forming. The transition cavity connects the pressure roller chamber and the grading and winding chamber; The graded winding chamber is divided into multiple independent winding chambers along the direction of membrane travel. A sealed compartment structure is provided between adjacent winding chambers to conduct or isolate the membrane material passage and air passage of adjacent winding chambers. A winding mechanism is provided in the winding chamber, and a feeding mechanism is provided at the bottom of the winding chamber. The feeding mechanism is used to drive the winding mechanism to make linear reciprocating motion in the direction of approaching or moving away from the winding chamber.

[0007] Furthermore, the sealed compartment structure is a liftable sealed door, and the sealed door is provided with sealing strips around its perimeter. When closed, it completely blocks the air passage and membrane material channel between adjacent winding chambers, and when open, it opens the membrane material channel and air passage.

[0008] Furthermore, the winding mechanism includes an air shaft, the axis of which is perpendicular to the direction of travel of the film material.

[0009] Furthermore, a correction structure is slidably provided on the feeding mechanism. The correction structure reciprocates linearly along the axis of the air expansion shaft, and the air expansion shaft is rotatably mounted on the correction structure.

[0010] Furthermore, the feeding mechanism includes a sliding rod assembly arranged opposite to each other, and a slide table slidably arranged on the sliding rod assembly. The axis of the sliding rod assembly is perpendicular to the direction of film material travel, and the correction structure is slidably arranged on the slide table.

[0011] Furthermore, the correction structure includes a guide rail assembly disposed opposite to the slide table, and a correction base slidably disposed on the guide rail assembly, wherein the axial direction of the guide rail assembly is parallel to the axial direction of the slide rod assembly.

[0012] Furthermore, the winding mechanism also includes a support rod fixedly mounted on the correction base, a fixed plate mounted on the support rod, the air shaft being rotatably connected to the fixed plate, a drive assembly mounted on the fixed plate, and the drive assembly being drively connected to the air shaft.

[0013] Furthermore, each winding chamber is equipped with an independent openable and closable operating door. The opening direction of the operating door corresponds to the movement direction of the unloading mechanism, and in the closed state, it is pressed and sealed against the periphery of the winding chamber.

[0014] The present invention also provides a feeding method for a hydrogen-barrier membrane winding device, comprising the following steps: Hydrogen gas is introduced into the pressure roller chamber from the sintering box, and some hydrogen gas is released through the hydrogen gas outlet at the top of the pressure roller chamber. The remaining hydrogen gas diffuses through the transition cavity to each level of the winding chamber, maintaining a slightly positive pressure hydrogen protective atmosphere in each chamber. After the film material is formed in the sintering box, it enters the pressure roller chamber to complete the roll forming, and then passes through the transition cavity into the winding chambers of each level, where the winding operation is performed by the corresponding winding mechanism. When the target winding chamber reaches the winding set value and needs to be changed for unloading, the sealing compartment structure on both sides of the winding chamber is closed to completely isolate the air passage and film material channel of the adjacent winding chamber. After depressurizing and venting the target winding chamber, the unloading mechanism drives the winding mechanism and the full roll film roller to move out of the winding chamber as a whole, unload the finished film roll and replace the empty core. The feeding mechanism drives the winding mechanism, which is equipped with empty cores, to reset into the chamber. After closing the operating door on the winding chamber, the target winding chamber is refilled with hydrogen. Once the atmosphere meets the standard, the sealed compartment structures on both sides are opened to resume normal winding operations.

[0015] Furthermore, during the winding process, the winding mechanism reciprocates and finely adjusts along the axial direction of the winding roller to correct any deviation in the film winding process in real time.

[0016] The technical solution of this invention can achieve the following technical effects: The adoption of a tiered, compartmentalized winding layout with independent unloading for each compartment solves the pain points of existing integrated sealed winding systems, such as significant interference during roll changing and insufficient atmosphere stability. Through an architecture where each chamber can be independently isolated by gas paths, roll changing and unloading operations only affect the target chamber, ensuring that the remaining chambers maintain a stable hydrogen protective atmosphere. This improves production continuity and operational efficiency, reduces hydrogen consumption, and prevents oxidation and degradation of the membrane material due to atmosphere fluctuations, effectively guaranteeing the performance consistency and production yield of the finished membrane.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] This invention provides a method such as Figures 1 to 5 The hydrogen-barrier membrane winding device shown includes: The sintering box 1, the pressure roller chamber 2, the transition cavity 3, and the grading and winding chamber 4 are connected sequentially along the direction of membrane material travel. The top of the pressure roller chamber 2 is provided with a hydrogen outlet 21, and the interior is provided with multiple sets of pressure roller assemblies 22 for film roll forming. The transition cavity 3 connects the pressure roller chamber 2 and the grading and winding chamber 4; The graded winding chamber 4 is divided into multiple independent winding chambers 41 along the direction of membrane material travel. A sealed compartment structure 42 is provided between adjacent winding chambers 41 to conduct or isolate the membrane material passage and air passage of adjacent winding chambers 41. A winding mechanism 41a is provided inside the winding chamber 41, and a feeding mechanism 41b is provided at the bottom of the winding chamber 41. The feeding mechanism 41b is used to drive the winding mechanism 41a to make linear reciprocating motion in the direction of approaching or moving away from the winding chamber 41.

[0024] The working principle of this invention is as follows: Along the direction of membrane material travel, a sintering chamber 1, a pressure roller chamber 2, a transition chamber 3, and a grading and winding chamber 4 are sequentially and sealed together. All chambers are fixedly connected by sealing flanges to ensure overall airtightness. The sintering chamber 1 serves as the front-end film-forming unit, used to complete the high-temperature sintering and forming of the membrane material, outputting a continuous membrane material with surface activity, and continuously supplying protective hydrogen gas into the pressure roller chamber 2. A hydrogen outlet 21 is centrally located at the top of the pressure roller chamber 2, used to continuously release some protective hydrogen gas and lower the pressure roller chamber. The hydrogen pressure inside the pressure roller chamber 2 is controlled by multiple sets of pressure roller assemblies 22 arranged along the film material's travel path. After the film material enters the pressure roller chamber 2, it is sequentially rolled by each set of pressure roller assemblies 22 under the protective atmosphere of residual hydrogen, completing the composite forming process. At the same time, the residual hydrogen can form a stable micro-positive pressure inside the pressure roller chamber 2, preventing outside air from seeping into the chamber from the feed end. The transition cavity 3 connects the pressure roller chamber 2 and the grading and winding chamber 4. The residual hydrogen gradually diffuses into the transition cavity 3, serving as a buffer channel for film material transportation and hydrogen diffusion, ensuring the flatness of the film material. A smooth transition into the winding section allows the hydrogen gas flow to diffuse gently into the subsequent winding area, preventing airflow fluctuations from affecting membrane stability. The internal structure of the graded winding chamber 4 is divided into three independent winding chambers 41 along the membrane material's travel direction. Each adjacent winding chamber 41 is separated by a sealed compartment structure 42. This sealed compartment structure 42 has two working states: open and closed. In the open state, the membrane material can pass through smoothly, while allowing hydrogen gas to flow freely between adjacent chambers to maintain a uniform protective atmosphere. In the closed state, it can completely seal the membrane material between adjacent chambers. The channels and air passages make the target winding chamber 41 a completely independent sealed space. Each winding chamber 41 is equipped with a winding mechanism 41a to receive the film material and complete the winding operation according to the set parameters. Each winding chamber 41 is equipped with a feeding mechanism 41b at the bottom. The feeding mechanism 41b moves in a direction perpendicular to the direction of the film material. It can drive the entire winding mechanism 41a to make linear reciprocating motion in the direction of approaching or moving away from the winding chamber 41, so as to realize the translational discharge and resetting of the film roll from the inside of the chamber to the outside.In actual operation, all sealed compartment structures 42 are first opened to connect the winding chambers 41 at each level. The hydrogen gas from the sintering chamber 1 continues to diffuse. After some of the hydrogen gas is released through the hydrogen outlet 21 at the top of the pressure roller chamber 2 to relieve pressure, the remaining hydrogen gas diffuses through the transition chamber 3 to the winding chambers 41 at each level. After the oxygen concentration in the entire chamber drops to the set threshold, a slightly positive pressure protective atmosphere is maintained. After the film material is formed at high temperature in the sintering chamber 1, it enters the pressure roller chamber 2 to complete the roll forming. Then, it passes through the transition chamber 3 and enters the winding chambers 41 at each level in sequence. The corresponding winding mechanism 41a winds the film at a uniform speed according to the set tension. When the film roll in one of the winding chambers 41 reaches the set roll diameter and needs to be changed, the winding action of that winding chamber 41 is stopped first, and then the sealed compartment structures 42 on both sides of the winding chamber 41 are closed to completely isolate the winding chamber 41 from the pressure roller. The air passages and film material channels of adjacent chambers create an independent, sealed space for the target winding chamber 41. The target winding chamber 41 is then depressurized and vented. The unloading mechanism 41b then drives the winding mechanism 41a and the full-roll film roller to move away from the chamber, feeding the film roll out of the winding chamber 41 and completing the unloading process. After replacing the empty core, the unloading mechanism 41b drives the winding mechanism 41a, now equipped with the empty core, to move in the opposite direction and reset back into the winding chamber 41. The winding chamber 41 is then sealed, and hydrogen is refilled into the target chamber for atmosphere replacement. Once the atmosphere meets the requirements, the sealing compartment structures 42 on both sides are opened, allowing the winding chamber 41 to resume normal winding operations. Throughout the entire roll changing and unloading process, the remaining unused winding chambers 41 maintain normal winding status and a hydrogen protective atmosphere, eliminating the need for a complete production line shutdown and effectively ensuring production continuity.

[0025] In some embodiments of the present invention, such as Figure 2 As shown, the sealed compartment structure 42 is a liftable sealed door 42a. Sealing strips are provided around the sealed door 42a. When closed, it completely blocks the air passage and membrane material channel between adjacent winding chambers 41. When open, it opens the membrane material channel and air passage.

[0026] A sealing partition door 42a is vertically installed on the partition wall between adjacent winding chambers 41. The partition wall has a through-membrane opening corresponding to the passage height of the membrane material. The door body of the sealing partition door 42a completely covers the through-membrane opening. The four sides of the door body are fitted with elastic sealing strips resistant to hydrogen atmosphere. The top or bottom of the sealing partition door 42a is connected to a linear lifting drive mechanism, which can drive the door body to move up and down along the vertically set guide structure. When it is necessary to separate adjacent chambers, the lifting drive mechanism drives the sealing partition door 42a to the closed position, and the door body completely blocks the through-membrane opening. The sealing strips around the door body are controlled by the door body and the partition wall. The compression of the wall generates elastic deformation, which fits tightly against the mating sealing surface, thereby completely blocking the air passage and membrane material channel between adjacent winding chambers 41, making the target winding chamber 41 an independent sealed space, meeting the process requirements of single-chamber isolation and roll changing; when it is necessary to open the chamber for normal winding operation, the lifting drive mechanism drives the sealing partition 42a to rise to the opening position, the membrane opening is fully opened, and the membrane material channel and air passage of the adjacent chamber are opened simultaneously, which can allow the continuous membrane material to pass through without obstruction, and also allow hydrogen to diffuse and circulate freely between each level of winding chamber 41, ensuring the uniform and stable protective atmosphere of each level of chamber under normal production conditions.

[0027] In some embodiments of the present invention, such as Figure 2 and Figure 4 As shown, the winding mechanism 41a includes an air shaft 41a1, the axis of which is perpendicular to the direction of travel of the film material.

[0028] The winding mechanism 41a uses an air shaft 41a1 as the core component for carrying the roll material and driving the winding. The air shaft 41a1 is arranged horizontally perpendicular to the direction of film material travel, and its axial direction is parallel to the front operating side of the winding chamber 41. The surface of the air shaft 41a1 is provided with multiple sets of radially expandable key structures. The shaft body has a connected air passage and an external inflation control element. In the inflation state, each set of expansion keys extends radially synchronously, which can tighten and fix paper or metal roll cores of different inner diameter specifications, ensuring that the core and shaft rotate synchronously without relative slippage during the winding process. In the depressurization state, the expansion keys automatically retract and completely separate from the inner wall of the core, which facilitates the quick unloading of the full roll film roller and the quick replacement of the empty core.

[0029] In some embodiments of the present invention, such as Figure 4 and Figure 5 As shown, a correction structure 43 is slidably arranged on the feeding mechanism 41b. The correction structure 43 moves linearly back and forth along the axis of the air expansion shaft 41a1, and the air expansion shaft 41a1 is rotatably arranged on the correction structure 43.

[0030] The top bearing side of the feeding mechanism 41b is slidably equipped with a correction structure 43. The sliding guide direction of the correction structure 43 is consistent with the axial direction of the air shaft 41a1, and it can make linear reciprocating motion in a horizontal direction perpendicular to the film material's movement. The two ends of the air shaft 41a1 are rotatably mounted on the support position of the correction structure 43 through bearing assemblies adapted to a hydrogen atmosphere, and the whole structure is adjusted axially synchronously with the correction structure 43. Under normal winding operation, the feeding mechanism 41b is locked and fixed in the winding working position. The correction structure 43 can drive the air shaft 41a1 according to the position detection result of the film material edge. Small reciprocating adjustments are made along the axial direction to correct the winding deviation of the membrane material in real time, ensuring that the membrane roll end face is neat and the layers are aligned, avoiding problems such as membrane misalignment and uneven winding. When the roll changing and unloading operation is triggered, the correction structure 43 locks and then completes the pulling and resetting actions away from the chamber together with the unloading mechanism 41b. The two sets of motion functions are independent of each other and do not interfere with each other, simplifying the structural layout inside the winding chamber 41, reducing the number of dynamic sealing points in the chamber to reduce the risk of hydrogen leakage and air infiltration, and also adapting to the limited internal space of the staged winding chamber 41, improving the integration and operational stability of single-chamber operation.

[0031] In some embodiments of the present invention, such as Figure 4 and Figure 5 As shown, the feeding mechanism 41b includes a sliding rod assembly 41b1 arranged opposite to each other, and a sliding table 41b2 slidably arranged on the sliding rod assembly 41b1. The axis of the sliding rod assembly 41b1 is perpendicular to the direction of film material travel, and the correction structure 43 is slidably arranged on the sliding table 41b2.

[0032] The slide bar assembly 41b1 includes two opposing and parallel slide bars, horizontally mounted on the bottom support base of the winding chamber 41 along a direction perpendicular to the film material's travel. The axial direction of the slide bars is aligned with the axial direction of the air shaft 41a1, providing precise linear motion guidance for the slide table 41b2. The bottom of the slide table 41b2 is equipped with suitable wear-resistant sliding bushings corresponding to the positions of the two slide bars. Through the sliding fit between the sliding bushings and the outer circumferential surface of the slide bar assembly 41b1, the slide table 41b2 can smoothly reciprocate along the axial direction of the slide bar assembly 41b1, supporting the slide table 41b2. The top surface of b2 is a flat mounting reference surface. The correction structure 43 is fixedly assembled on the top surface of the slide table 41b2. It can complete the large stroke pulling motion of entering and exiting the winding chamber 41 together with the slide table 41b2. At the same time, it can complete the small stroke correction adjustment on the top surface of the slide table 41b2. The two sets of motion share the same bearing guide foundation, which reduces the overall height occupied by the mechanism, adapts to the limited installation space at the bottom of the winding chamber 41, and also ensures the coaxiality of the correction motion and the unloading motion, avoiding mechanism jamming and chamber seal wear caused by deviation of the motion direction.

[0033] In some embodiments of the present invention, such as Figure 4 and Figure 5As shown, the correction structure 43 includes a guide rail assembly 43a disposed opposite to the slide table 41b2, and a correction base 43b slidably disposed on the guide rail assembly 43a. The axial direction of the guide rail assembly 43a is parallel to the axial direction of the slide rod assembly 41b1.

[0034] The correction structure 43 includes two opposing and parallel guide rails, and a correction base 43b slidably mounted on the guide rail assembly 43a. The guide rail assembly 43a is symmetrically fixed on the top surface of the slide table 41b2 along the axial direction of the air expansion shaft 41a1, and the axial direction of the guide rail assembly 43a is completely parallel to the axial direction of the lower slide rod assembly 41b1, so that the correction adjustment direction is coaxial with the material feeding and pulling direction. The guide rail assembly 43a adopts a high-precision linear guide rail pair adapted to a hydrogen protective atmosphere. The bottom of the correction base 43b is equipped with a matching slider assembly corresponding to the positions of the two guide rail assemblies 43a. The slider and the guide rail... To facilitate smooth reciprocating sliding along the guide rail axis, the top surface of the correction base 43b serves as the installation reference surface, supporting and fixing the two end support components of the air shaft 41a1, allowing the air shaft 41a1 to adjust its axial position together with the correction base 43b. During normal winding operations, the lower slide table 41b2 is locked in the working position, and the correction base 43b can perform small-stroke reciprocating linear motion along the guide rail assembly 43a under the drive of the matching drive element, thereby driving the air shaft 41a1 to make precise micro-adjustments along its own axis, correcting the winding deviation of the film material in real time, and ensuring the neatness of the film roll end face.

[0035] In some embodiments of the present invention, such as Figure 4 and Figure 5 As shown, the winding mechanism 41a also includes a support rod 41a2 fixedly mounted on the correction base 43b, a fixing plate 41a3 mounted on the support rod 41a2, an air shaft 41a1 rotatably connected to the fixing plate 41a3, a drive assembly 41a4 mounted on the fixing plate 41a3, and a drive assembly 41a4 being connected to the air shaft 41a1 in a transmission manner.

[0036] The support rods 41a2 can be arranged in two, fixedly mounted at intervals on the top surface of the alignment base 43b along the direction of membrane travel. A vertically arranged fixing plate 41a3 is fixedly mounted on the top of the two support rods 41a2, so that the fixing plate 41a3 is mounted on the alignment base 43b and maintains a stable installation posture. The air shaft 41a1 is rotatably mounted on the side wall of the fixing plate 41a3 via a sealed bearing adapted to a hydrogen protective atmosphere. The main body of the shaft extends outward in a cantilever shape along the direction perpendicular to the direction of membrane travel. A drive assembly 41a4 is fixedly mounted on the outer side wall of the fixing plate 41a3 corresponding to the drive end of the air shaft 41a1. The drive assembly 41a4 can be servo driven. The structure of the motor paired with the transmission pair allows the output power of the drive motor to be transmitted to the transmission end of the air shaft 41a1 via the transmission pair, driving the shaft to rotate at a set speed. This, combined with the tension control logic, enables constant tension winding. The free end of the air shaft 41a1 is unobstructed, allowing the fully rolled film roller to be directly detached from the free end along the axial direction of the air shaft 41a1. This eliminates the need for additional disassembly of the shaft end support components, simplifying the single-compartment roll changing process and shortening the roll changing time. At the same time, the entire support and drive structure is integrated and fixed on the correction base 43b, allowing for axial correction and fine-tuning along the guide rail assembly 43a together with the correction base 43b. The transmission relationship remains stable at all times.

[0037] In some embodiments of the present invention, such as Figure 3 As shown, each winding chamber 41 is equipped with an independent openable and closable operating door 42. The opening direction of the operating door 42 corresponds to the movement direction of the feeding mechanism 41b. When closed, it is pressed and sealed against the periphery of the winding chamber 41.

[0038] The opening position of the operating door 42 is directly opposite to the pull-out path of the unloading mechanism 41b inside the chamber, and the opening direction corresponds to the linear movement direction of the unloading mechanism 41b. The overall outline dimension of the operating door 42 is larger than the maximum outer diameter of the full roll film roller and the overall outline dimension of the winding mechanism 41a, ensuring that there is no structural interference when the film roll is pulled in and out with the unloading mechanism 41b. The entire inner circumference of the operating door 42 can be fitted with a weather-resistant elastic sealing strip adapted to the hydrogen protective atmosphere. The operating door 42 is equipped with multiple sets of evenly distributed locking mechanisms, thereby achieving a tight seal between the winding door and the periphery of the chamber, and stably maintaining the hydrogen protective atmosphere inside the winding chamber 41. During normal winding operations, the operating hatch 42 remains closed and locked to ensure the airtightness of the winding chamber 41. When the target winding chamber 41 needs to be changed and unloaded, after the winding chamber 41 has completed the depressurization and exhaust process, the locking mechanism can be released to open the operating hatch 42. Then, the unloading mechanism 41b drives the winding mechanism 41a and the full roll film roller to move out of the chamber along the axial direction from the hatch opening. After completing the unloading and empty core replacement operations, the unloading mechanism 41b returns to the chamber. Changing a single winding chamber 41 only requires opening the corresponding hatch. The operating hatches 42 of the other unoperated winding chambers 41 remain closed and sealed, which will not interfere with the protective atmosphere of the overall production line. This ensures the reliability of hydrogen isolation while improving the convenience and efficiency of the winding change operation.

[0039] Based on the same inventive concept as the hydrogen-isolated film winding device described in the foregoing embodiments, the present invention also provides a feeding method for the hydrogen-isolated film winding device, such as... Figure 6 As shown, it includes the following steps: Hydrogen gas is introduced into the pressure roller chamber from the sintering box, and some hydrogen gas is released through the hydrogen gas outlet 21 at the top of the pressure roller chamber 2. The remaining hydrogen gas diffuses through the transition chamber 3 to each level of winding chamber 41 to maintain a slightly positive pressure hydrogen protective atmosphere in each chamber. After the film material is formed in the sintering box 1, it enters the pressure roller chamber 2 to complete the roll forming, and then passes through the transition cavity 3 to enter the winding chambers 41 of each level in sequence, where the winding operation is performed by the corresponding winding mechanism 41a. When the target winding chamber 41 reaches the winding set value and needs to be changed and unloaded, the sealing compartment structure 42 on both sides of the winding chamber 41 is closed, completely isolating the air passage and film material passage of the adjacent winding chamber 41. After depressurizing and venting the target winding chamber 41, the unloading mechanism 41b drives the winding mechanism 41a and the full roll film roller to move out of the winding chamber 41 as a whole, unload the finished film roll and replace the empty core. The feeding mechanism 41b drives the winding mechanism 41a, which is equipped with empty core, to reset into the chamber. After closing the operation door 42 on the winding chamber 41, the target winding chamber 41 is refilled with hydrogen. Once the atmosphere meets the standard, the sealing compartment structure 42 on both sides is opened to resume normal winding operation.

[0040] The feeding method described above in this invention can be effectively applied to hydrogen-barrier film winding devices, and the technical effects achieved are as described in the above embodiments, which will not be repeated here.

[0041] In some embodiments of the present invention, during the winding operation, the winding mechanism 41a reciprocates and finely adjusts along the axial direction of the winding roller to correct the film material winding deviation in real time, that is, the winding mechanism 41a reciprocates and finely adjusts along the axial direction of the air expansion shaft 41a1.

[0042] Similarly, the above-mentioned optimization schemes for the method can also respectively achieve the optimization effects of the methods in the embodiments, which will not be repeated here.

[0043] Although this application has been described in conjunction with specific features and embodiments, it is obvious that various modifications and combinations can be made thereto without departing from the spirit and scope of this application. Accordingly, this specification and drawings are merely exemplary illustrations of the application as defined herein, and are to be considered as covering any and all modifications, variations, combinations, or equivalents within the scope of this application. Clearly, those skilled in the art can make various alterations and modifications to this application without departing from its scope. Thus, if such modifications and modifications fall within the scope of this application and its equivalents, this application intends to include such modifications and modifications.
