Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a film storage device. Background Technology

[0002] In battery production lines, adjacent cells in a cell module need to be bonded together using adhesive film, which is typically stacked vertically and stored in a cassette. However, there are many existing cell specifications, each with different dimensions, resulting in a variety of adhesive film sizes. When the production line needs to change the cell specifications it produces, a corresponding cassette is required to store the matching adhesive film, leading to the need for multiple cassette sizes. Changing the cassette every time the production line changes cell specifications is cumbersome, and the multiple cassettes also occupy excessive space. Utility Model Content

[0003] The purpose of this application is to provide a film storage device to solve the technical problem that the existing material boxes cannot be adapted to different specifications of film, and the material boxes need to be replaced every time the specifications of the film to be produced are changed. This is not only cumbersome to operate, but also takes up too much space due to the use of multiple different material boxes.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] A film storage device includes a base and a plurality of material boxes disposed on the base. The plurality of material boxes are arranged in N columns along a first horizontal direction, and at least one material box is arranged in each column along a second horizontal direction. N is greater than or equal to 1, and the first horizontal direction and the second horizontal direction are perpendicular to each other.

[0006] Each hopper includes a first limiting structure, a second limiting structure, a third limiting structure, and a fourth limiting structure, wherein: the first limiting structure and the second limiting structure are arranged opposite to each other along a first horizontal direction, and both are slidably mounted on a base along the first horizontal direction; the third limiting structure and the fourth limiting structure are arranged opposite to each other along a second horizontal direction, with the third limiting structure mounted on the base and the fourth limiting structure slidably mounted on the base along the second horizontal direction; the first limiting structure, the second limiting structure, the third limiting structure, and the fourth limiting structure together form a storage area for vertically stacking film;

[0007] When there are multiple material bins, each of the first limit structures works in conjunction with the other of the second limit structures.

[0008] The film storage device provided in this application can adapt to different film specifications, solving the technical problem in the prior art where the material box needs to be replaced every time the film specification is changed. Furthermore, in this film storage device, when there are multiple material boxes, the various first limiting structures and the various second limiting structures work together in a coordinated manner. Therefore, controlling any one of the first limiting structures to slide on the base will cause the other first limiting structures to slide synchronously, and controlling any one of the second limiting structures to slide on the base will cause the other second limiting structures to slide synchronously. This allows for simultaneous adjustment of the size of all material boxes, simplifying the operation steps and improving adjustment efficiency.

[0009] In some embodiments, a first locking component is disposed between at least one first limiting structure and the base, the first locking component being configured to lock and release the positions of each first limiting structure on the base. In some embodiments, a second locking component is disposed between at least one second limiting structure and the base, the second locking component being configured to lock and release the positions of each second limiting structure on the base.

[0010] The term "at least one" as used above includes: one of them, multiple of them, and each. Because the various first limiting structures work in conjunction, meaning all the first limiting structures move synchronously, locking the position of one first limiting structure on the base simultaneously locks the positions of the remaining first limiting structures on the base. Similarly, locking the position of one second limiting structure on the base simultaneously locks the positions of the remaining second limiting structures on the base.

[0011] In some embodiments, a third locking component is provided between each fourth limiting structure and the base, and the third locking component is configured to lock and release the position of the corresponding fourth limiting structure on the base;

[0012] Alternatively, several material boxes are arranged in at least one row along the second horizontal direction. When N is greater than 1, each fourth limiting structure in each row of material boxes is linked and coordinated. At least one fourth limiting structure in each row of material boxes is provided with a third locking component between it and the base. The third locking component is configured to lock and release the position of each fourth limiting structure in each row of material boxes on the base.

[0013] In embodiments where the fourth limiting structures in each bin move independently, a third locking component is required between each fourth limiting structure and the base. In embodiments where the fourth limiting structures in each row of bins move in tandem, locking the position of one fourth limiting structure in each row of bins on the base will simultaneously lock the positions of the remaining fourth limiting structures in each row of bins on the base.

[0014] In some embodiments, each column of material boxes is provided with a first sliding plate and a second sliding plate on opposite sides along a first horizontal direction, and the first limiting structure in each column of material boxes is fixed on the corresponding first sliding plate, and the second limiting structure in each column of material boxes is fixed on the corresponding second sliding plate.

[0015] When the first sliding plate slides on the base, the first limiting structures on the first sliding plate slide synchronously; when the second sliding plate slides on the base, the second limiting structures on the second sliding plate slide synchronously. The first sliding plate enables the coordinated operation of the first limiting structures in each row of material bins, and the second sliding plate enables the coordinated operation of the second limiting structures in each row of material bins.

[0016] In some embodiments, when N is greater than 1, the film storage device further includes a first linkage rod, which extends along a first horizontal direction and is sequentially fixed to each of the first sliding plates;

[0017] And / or, when N is greater than 1, the film storage device further includes a second linkage rod, which extends along a first horizontal direction and is sequentially fixed to each of the second slide plates.

[0018] The first sliding plate and the first linkage rod enable the linkage of each first limiting structure, allowing all the first limiting structures to move synchronously; the second sliding plate and the second linkage rod enable the linkage of each second limiting structure, allowing all the second limiting structures to move synchronously.

[0019] In some embodiments, a first locking assembly is provided between at least one first slide plate and a base. The base has a first T-slot extending along a first horizontal direction. The first locking assembly includes a first slider, a first fixing plate, and a first locking bolt, wherein: the first slider is slidably disposed in the first T-slot; the first end of the first fixing plate is fixedly connected to the corresponding first slide plate, and the second end of the first fixing plate extends to the opening of the first T-slot and is disposed opposite to the first slider; the first locking bolt passes through the first fixing plate and is screwed to the first slider, and the two sides of the opening of the first T-slot are clamped between the first fixing plate and the first slider.

[0020] When the first locking bolt is tightened, the two edges of the opening of the first T-slot are clamped between the first fixed plate and the first slider, thereby fixing the first slide plate connected to the first fixed plate to the base. Since the first linkage rod connects the various first slide plates to form a whole, fixing one of the first slide plates can fix all the first slide plates to the base. When it is necessary to adjust the size of the hopper, loosen the first locking bolt, and then push all the first slide plates to slide on the base along the first horizontal direction; when the first slide plates slide to the appropriate position, tighten the first locking bolt to fix all the first slide plates to the base again.

[0021] In some embodiments, a second locking assembly is provided between at least one second slide plate and a base. The base has a second T-shaped groove extending along a first horizontal direction. The second locking assembly includes a second slider, a second fixing plate, and a second locking bolt, wherein: the second slider is slidably disposed in the second T-shaped groove; the first end of the second fixing plate is fixedly connected to the corresponding second slide plate, and the second end of the second fixing plate extends to the opening of the second T-shaped groove and is disposed opposite to the second slider; the second locking bolt passes through the second fixing plate and is screwed to the second slider, and the two sides of the opening of the second T-shaped groove are clamped between the second fixing plate and the second slider.

[0022] When the second locking bolt is tightened, the two edges of the second T-slot opening are clamped between the second fixed plate and the second slider, thereby fixing the second slide plate connected to the second fixed plate to the base. Since the second linkage rod connects the various second slide plates to form a whole, fixing one second slide plate can fix all the second slide plates to the base. When it is necessary to adjust the size of the hopper, loosen the second locking bolt, and then push all the second slide plates to slide on the base along the first horizontal direction; when the second slide plates slide to the appropriate position, tighten the second locking bolt to fix all the second slide plates to the base again.

[0023] In some embodiments, a movable mounting seat is provided on the base corresponding to the position of each fourth limiting structure, and a third locking assembly is provided between each fourth limiting structure and the base. The third locking assembly includes a fixing member and a movable member, wherein:

[0024] The fastener is disposed on the base and extends along the second horizontal direction, and the fastener has multiple limiting features distributed sequentially along the second horizontal direction;

[0025] The movable mounting base is slidably mounted on the base along the second horizontal direction. The fourth limiting structure and the movable component are both mounted on the corresponding movable mounting base. The movable component can be locked or separated from any limiting feature on the fixed component.

[0026] In the above structure, when the movable part is locked to one or more of the limiting features on the fixed part, the fourth limiting structure is fixed to the base. When it is necessary to adjust the size of the hopper, the mutually locked movable part and limiting feature are separated, and then the movable mounting base and its fourth limiting structure and movable part are pushed to slide synchronously along the second horizontal direction on the base; when the fourth limiting structure slides to the appropriate position, the movable part is locked to the limiting feature corresponding to that position, at which point the fourth limiting structure is re-fixed to the base.

[0027] In some embodiments, the movable member is slidably disposed on the movable mounting base in a direction approaching or away from the fixed member;

[0028] The fixed part is a rack, the limiting feature is the teeth on the rack, and the movable part is a rack, gear, or insert with a pointed tip; or, the limiting feature is a hole on the fixed part, the movable part is a rod, and the movable part can be inserted into any hole.

[0029] The third locking assembly also includes an elastic element, the two ends of which are connected to the movable element and the movable mounting base, respectively.

[0030] When the above structure is not subjected to external force, the movable part, driven by the elastic element, locks with one or more of the limiting features on the fixed part. At this time, the fourth limiting structure is fixed to the base. When it is necessary to adjust the position of the fourth limiting structure, the movable part is manually lifted to separate it from the fixed part. Then, the fourth limiting structure is pushed to the appropriate position and the movable part is released. Driven by the elastic element, the movable part re-contacts the fixed part and locks with the limiting feature corresponding to that position. At this time, the fourth limiting structure is fixed to the base again.

[0031] In some embodiments, the limiting feature is a threaded hole formed on the fixing member, and the movable member is a screw rod that can be rotatably mounted on the mounting base. The movable member can be screwed into the threaded hole on any of the fixing members.

[0032] The above structure can also lock or separate any limiting feature on the moving part and the fixed part, so that the third locking component can lock and release the position of the corresponding fourth limiting structure on the base.

[0033] In some embodiments, at least one brush is provided on the base corresponding to the position of each storage area, each brush is located at the top edge of the corresponding storage area, and the bristles of each brush can extend horizontally into the corresponding storage area.

[0034] When the brush is working normally, the bristles are horizontal and extend into the corresponding storage area; during the process of the top film being removed from the storage area, the brush can prevent the film below from leaving the storage area along with the film being removed.

[0035] In some embodiments, a mounting base is provided on the base corresponding to the position of each brush, and each brush is rotatably or slidably mounted on the corresponding mounting base;

[0036] The brush has two extreme positions before and after rotating or sliding relative to the corresponding mounting base, namely the first position and the second position; when the brush is in the first position, the bristles of the brush extend horizontally into the corresponding storage area; when the brush is in the second position, the entire brush is located outside the corresponding storage area.

[0037] When the brush is working normally, it is in the first position. At this time, the brush can prevent the film below from leaving the storage area with the film that has been removed. When the film in the storage area is used up, a new set of film needs to be added to the storage area from top to bottom. At this time, the brush is controlled to rotate or slide relative to the corresponding mounting base, so that the brush moves to the second position. Since the brush in the second position is located outside the corresponding storage area, it will not obstruct the replenishment of film.

[0038] In some embodiments, the mounting base includes a column disposed on a base and a limiting block disposed on the top of the column. The limiting block has a first limiting surface and a second limiting surface that are perpendicular to each other. A first magnet is embedded in the first limiting surface and a second magnet is embedded in the second limiting surface.

[0039] The brush is rotated and mounted on the corresponding column; when the brush rotates to the first position, the brush abuts against the first limiting surface and is magnetically attracted to the first magnet; when the brush rotates to the second position, the brush abuts against the second limiting surface and is magnetically attracted to the second magnet.

[0040] When the brush rotates to abut against the first limiting surface, the brush bristles are in a horizontal state, and the first magnet magnetically engages with the brush to stably hold the brush in this state. When the brush rotates to abut against the second limiting surface, the brush bristles are in a vertical state, and the second magnet magnetically engages with the brush to stably hold the brush in this state.

[0041] In some embodiments, at least two of the first limiting structure, second limiting structure, third limiting structure and fourth limiting structure of each hopper are respectively provided with a brush on their top.

[0042] The above arrangement provides a brush at least on each of the two sides of the top of each storage area. During the removal of the top film from the storage area, at least two edges of the top film must be swept downwards by the brushes, ensuring that the lower film is not carried away by the top film.

[0043] In some embodiments, multiple bins are arranged in two rows along the second horizontal direction, and in each row of two bins, two third limiting structures are disposed between two fourth limiting structures.

[0044] When N is greater than 1, each of the third limiting structures in each row of bins is on the same straight line extending along the first horizontal direction.

[0045] When the dimensions of the aforementioned multiple material bins are adjusted, each third limiting structure remains fixed relative to the base, serving as a positioning reference for the film. Since each row of third limiting structures is located on the same straight line extending along the first horizontal direction, each third limiting structure provides a unified positioning reference for the film in different storage areas, facilitating the precise placement and removal of the film.

[0046] In some embodiments, the base includes a rectangular frame and a bottom plate laid flat on the top surface of the rectangular frame. The first limiting structure, the second limiting structure, the third limiting structure and the fourth limiting structure are all two spaced round rods. The bottom plate is provided with clearance holes for the first limiting structure, the second limiting structure, the third limiting structure and the fourth limiting structure to pass through.

[0047] The above structure provides a flat supporting surface for the film by laying a base plate on the rectangular frame. Attached Figure Description

[0068] The technical solutions of this application will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0069] It should be noted that in the description of this application, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0070] It should be noted that, in the description of this application, the terms "connection" and "installation" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through an intermediate medium; they can refer to a mechanical connection or an electrical connection. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0071] To address the technical problem that existing film storage cassettes cannot accommodate films of different specifications, this application provides a film storage device, referring to... Figure 1 The film storage device includes a base 1 and a plurality of material boxes 2 disposed on the base 1. The plurality of material boxes 2 are arranged in N columns along a first horizontal direction, and at least one material box 2 is arranged in each column along a second horizontal direction. N is greater than or equal to 1, and the first horizontal direction and the second horizontal direction are perpendicular to each other.

[0072] Each hopper 2 includes a first limiting structure 21, a second limiting structure 22, a third limiting structure 23, and a fourth limiting structure 24, wherein: the first limiting structure 21 and the second limiting structure 22 are arranged opposite to each other along a first horizontal direction, and both are slidably arranged on the base 1 along the first horizontal direction; the third limiting structure 23 and the fourth limiting structure 24 are arranged opposite to each other along a second horizontal direction, the third limiting structure 23 is arranged on the base 1, and the fourth limiting structure 24 is slidably arranged on the base 1 along the second horizontal direction; the first limiting structure 21, the second limiting structure 22, the third limiting structure 23, and the fourth limiting structure 24 together form a storage area for vertically stacking films;

[0073] When there are multiple material bins 2, each of the first limiting structures 21 and each of the second limiting structures 22 work together in a coordinated manner.

[0074] In the above structure, assuming that Q bins 2 are distributed sequentially along the second horizontal direction in each row, then the base 1 has a total of N×Q bins 2. For example, when N equals 1 and Q equals 1, the base 1 has only 1 bin 2; when N equals 4 and Q equals 2, the base 1 has two rows and four columns, totaling 8 bins 2; when N equals 4 and Q equals 4, the base 1 has four rows and four columns, totaling 16 bins 2. Each bin 2 forms a storage area, that is, the base 1 has one storage area or multiple storage areas arranged in a matrix.

[0075] Using the film storage device provided in this application, when it is necessary to replace films of different specifications, taking one of the material bins 2 as an example, one way to adjust the size of the material bin 2 is as follows: control the first limiting structure 21 and the second limiting structure 22 to slide along the first horizontal direction on the base 1, so that the two move towards each other or away from each other, thereby adjusting the distance between the first limiting structure 21 and the second limiting structure 22; then, fix the third limiting structure 23 and control the fourth limiting structure 24 to slide along the second horizontal direction on the base 1, so that the fourth limiting structure 24 approaches or moves away from the third limiting structure 23, thereby adjusting the distance between the third limiting structure 23 and the fourth limiting structure 24; through the above operation, the size of the storage area formed by the combination of each limiting structure can be adjusted so that the size of the storage area is adapted to the size of the film to be placed.

[0076] As described above, the film storage device provided in this application can adapt to films of different specifications, solving the technical problem in the prior art that the material box needs to be replaced every time the film specification is changed. In addition, in this film storage device, when there are multiple material boxes 2, each of the first limiting structures 21 and each of the second limiting structures 22 are linked and coordinated. Therefore, controlling any one of the first limiting structures 21 to slide on the base 1 will cause the other first limiting structures 21 to slide synchronously, and controlling any one of the second limiting structures 22 to slide on the base 1 will cause the other second limiting structures 22 to slide synchronously. This allows the size of all material boxes 2 to be adjusted simultaneously, simplifying the operation steps and improving the adjustment efficiency.

[0077] In some embodiments, the third limiting structure 23 is fixed to the base 1. The size adjustment method of the hopper 2 in this embodiment is as described above.

[0078] In other embodiments, the third limiting structure 23 is slidably disposed on the base 1 along the second horizontal direction. The size of the hopper 2 in this embodiment can be adjusted by controlling the first limiting structure 21 and the second limiting structure 22 to slide along the first horizontal direction on the base 1, causing them to move towards each other or away from each other, thereby adjusting the distance between the first limiting structure 21 and the second limiting structure 22; then, controlling the third limiting structure 23 and the fourth limiting structure 24 to slide along the second horizontal direction on the base 1, causing them to move towards each other or away from each other, thereby adjusting the distance between the third limiting structure 23 and the fourth limiting structure 24.

[0079] Preferably, the third limiting structure 23 is fixed on the base 1. Before and after the size of the material box 2 is adjusted, the relative position of the third limiting structure 23 and the base 1 remains unchanged, which can serve as a positioning reference for the loading and unloading of films of different specifications.

[0080] Continue to refer to Figure 1In the illustrated embodiment, multiple material bins 2 are arranged in two rows along the second horizontal direction (i.e., two material bins 2 are arranged in each row along the second horizontal direction). In each row of two material bins 2, two third limiting structures 23 are arranged between two fourth limiting structures 24. Further, when N is greater than 1, each third limiting structure 23 in each row of material bins 2 is on the same straight line extending along the first horizontal direction. When the dimensions of the multiple material bins 2 are adjusted, each third limiting structure 23 is fixed relative to the base 1, and each third limiting structure 23 serves as a positioning reference for the film. Since each third limiting structure 23 in each row is on the same straight line extending along the first horizontal direction, each third limiting structure 23 provides a unified positioning reference for the film in different storage areas, facilitating the accurate placement and removal of the film.

[0081] Reference Figure 1 and Figure 2 In some embodiments, the base 1 includes a rectangular frame 12 and a base plate 13 laid flat on the top surface of the rectangular frame 12. The first limiting structure 21, the second limiting structure 22, the third limiting structure 23, and the fourth limiting structure 24 are all two spaced-apart round rods. The base plate 13 has clearance holes for the first limiting structure 21, the second limiting structure 22, the third limiting structure 23, and the fourth limiting structure 24 to pass through. The round rods can also be replaced by upright plates or prisms; in addition, the number of round rods in each limiting structure can be more than two.

[0082] Optionally, the base plate 13 can be a split base plate or a one-piece base plate. When the base plate 13 is a split base plate, such as... Figure 3 As shown, a base plate 13 is provided at the bottom of each bin 2 or at the bottom of each row of bins 2. When the base plate 13 is an integral base plate, the top surface of the rectangular frame 12 is covered by a base plate 13, and the orthographic projection of each bin 2 on the top surface of the rectangular frame 12 is within the orthographic projection range of the base plate 13 on the top surface of the rectangular frame 12. Preferably, the base plate 13 is a split base plate, which facilitates both the cutting of the base plate 13 and the assembly of each bin 2.

[0083] Reference Figure 2 In some embodiments, a first locking component 7 is provided between at least one first limiting structure 21 and the base 1. The first locking component 7 is configured to lock and release the positions of each first limiting structure 21 on the base 1. The term "at least one" includes: one of them, multiple of them, and each one. Since the first limiting structures 21 are linked and cooperate, that is, all the first limiting structures 21 operate synchronously, locking the position of one first limiting structure 21 on the base 1 will also lock the positions of the remaining first limiting structures 21 on the base 1 synchronously.

[0084] In some embodiments, a second locking component is provided between at least one second limiting structure 22 and the base 1. The second locking component is configured to lock and release the positions of each second limiting structure 22 on the base 1. Since each second limiting structure 22 is linked and cooperates, locking the position of one second limiting structure 22 on the base 1 will simultaneously lock the positions of the remaining second limiting structures 22 on the base 1.

[0085] In some embodiments, a third locking component 8 is provided between each fourth limiting structure 24 and the base 1. The third locking component 8 is configured to lock and release the position of the corresponding fourth limiting structure 24 on the base 1. In other embodiments, a plurality of material boxes 2 are arranged in at least one row along a second horizontal direction. When N is greater than 1, each fourth limiting structure 24 in each row of material boxes 2 is linked and cooperates. A third locking component 8 is provided between at least one fourth limiting structure 24 in each row of material boxes 2 and the base 1. The third locking component 8 is configured to lock and release the position of each fourth limiting structure 24 in each row of material boxes 2 on the base 1.

[0086] In embodiments where the fourth limiting structures 24 in each material bin 2 move independently, a third locking assembly 8 is required between each fourth limiting structure 24 and the base 1. In embodiments where the fourth limiting structures 24 in each row of material bins 2 move in conjunction, locking the position of one fourth limiting structure 24 in each row of material bins 2 on the base 1 will simultaneously lock the positions of the remaining fourth limiting structures 24 in each row of material bins 2 on the base 1.

[0087] Reference Figure 2 and Figure 3 In some embodiments, each column of material bins 2 is provided with a first sliding plate 3 and a second sliding plate 4 on opposite sides along a first horizontal direction. The first limiting structures 21 in each column of material bins 2 are fixed to the corresponding first sliding plate 3, and the second limiting structures 22 in each column of material bins 2 are fixed to the corresponding second sliding plate 4. The first sliding plate 3 and the second sliding plate 4 are slidably mounted on the base 1 along the first horizontal direction. When the first sliding plate 3 is controlled to slide on the base 1, each first limiting structure 21 on the first sliding plate 3 slides synchronously. When the second sliding plate 4 is controlled to slide on the base 1, each second limiting structure 22 on the second sliding plate 4 slides synchronously. The first sliding plate 3 enables the coordinated operation of each first limiting structure 21 in each column of material bins 2, and the second sliding plate 4 enables the coordinated operation of each second limiting structure 22 in each column of material bins 2.

[0088] In some embodiments, when N is greater than 1, the film storage device further includes a first linkage rod 5, which extends along a first horizontal direction and is sequentially fixed to each of the first sliding plates 3. For example... Figure 2As shown, the number of first slide plates 3 and second slide plates 4 is the same as the number of columns of the material box 2, that is, the number of first slide plates 3 and second slide plates 4 is N; when N is greater than 1, the first slide plates 3 and second slide plates 4 are alternately distributed along the first horizontal direction; a first connecting seat is fixed on the bottom surface of each first slide plate 3, and the first linkage rod 5 passes through the first connecting seat on each first slide plate 3 in sequence and is locked to each first connecting seat by bolts, and the first slide plates 3 are connected to form a whole by the first linkage rod 5.

[0089] In some embodiments, when N is greater than 1, the film storage device further includes a second linkage 6, which extends along a first horizontal direction and is sequentially fixed to each of the second slide plates 4. Figure 2 As shown, when N is greater than 1, a second connecting seat is fixed on the bottom surface of each second slide plate 4, and the second linkage rod 6 passes through the second connecting seat on each second slide plate 4 in sequence and is locked to each second connecting seat by bolts.

[0090] In some embodiments, when N is greater than 1, the film storage device further includes a first linkage rod 5 and a second linkage rod 6. The first linkage rod 5 and the second linkage rod 6 are distributed parallel to each other at the bottom of each material box 2. The first linkage rod 5 extends along a first horizontal direction and is sequentially fixed to each first slide plate 3, and the second linkage rod 6 extends along the first horizontal direction and is sequentially fixed to each second slide plate 4. In the above structure, the first slide plate 3 and the first linkage rod 5 realize the linkage cooperation of each first limiting structure 21, so that all the first limiting structures 21 move synchronously; the second slide plate 4 and the second linkage rod 6 realize the linkage cooperation of each second limiting structure 22, so that all the second limiting structures 22 move synchronously.

[0091] In some other embodiments, multiple first links are used instead of the first linkage 5, and two adjacent first slide plates 3 are fixedly connected by a first link; multiple second links are used instead of the second linkage 6, and two adjacent second slide plates 4 are fixedly connected by a second link.

[0092] In some embodiments, when N is greater than 1, the film storage device further includes at least one third linkage rod (not shown in the figure), with each third linkage rod corresponding to at least one row of material boxes 2. All fourth limiting structures 24 in each row of material boxes 2 are fixedly connected to their corresponding third linkage rods. In the above structure, the linkage rods enable the coordinated operation of each fourth limiting structure 24 in each row of material boxes 2, allowing all fourth limiting structures 24 in each row of material boxes 2 to operate synchronously.

[0093] In some embodiments, a first locking assembly 7 is provided between at least one first sliding plate 3 and a base 1. The base 1 is provided with a first T-slot 11 extending along a first horizontal direction. The first locking assembly 7 includes a first slider 71, a first fixing plate 72, and a first locking bolt, wherein: the first slider 71 is slidably disposed in the first T-slot 11; the first end of the first fixing plate 72 is fixedly connected to the corresponding first sliding plate 3, and the second end of the first fixing plate 72 extends to the opening of the first T-slot 11 and is disposed opposite to the first slider 71; the first locking bolt passes through the first fixing plate 72 and is screwed to the first slider 71, and the two sides of the opening of the first T-slot 11 are clamped between the first fixing plate 72 and the first slider 71.

[0094] It should be noted that the T-slot is a groove with a cross-section resembling a T. The first slider 71 is constrained between the two sides of the opening of the first T-slot 11 and the bottom surface of the groove. When the first locking bolt is tightened, the two sides of the opening of the first T-slot 11 are clamped between the first fixing plate 72 and the first slider 71. At this time, the first slider 71 is fixed at a certain position within the first T-slot 11. When the first locking bolt is loosened, the first fixing plate 72 and the first slider 71 release the clamping force on the two sides of the opening of the first T-slot 11. At this time, the first slider 71 can slide along the first horizontal direction within the first T-slot 11.

[0095] Figure 2 In the illustrated embodiment, the base 1 has a first T-shaped groove 11 on each of its two opposite outer surfaces along the second horizontal direction, and one of the first sliding plates 3 (specifically...) Figure 2 A first locking assembly 7 is respectively provided between the two ends of the second horizontal direction (from bottom to top) of the first slide plate 3 and the base 1. The first locking assemblies 7 at both ends of the first slide plate 3 correspond one-to-one with the two first T-slots 11. Taking one set of first locking assemblies 7 as an example for explanation, refer to... Figure 4 The first slider 71 is slidably disposed in the corresponding first T-slot 11. The first fixing plate 72 is an L-shaped bent plate, the horizontal section of which is fixed to the bottom of the first slide plate 3 by bolts, and the vertical section extends to the opening of the corresponding first T-slot 11 and is disposed opposite to the first slider 71. A through hole is provided on the vertical section, and a threaded hole is provided on the first slider 71. The first locking bolt passes through the through hole on the vertical section and is screwed into the threaded hole on the first slider 71. When the first locking bolt is tightened, the two sides of the opening of the first T-slot 11 are clamped between the vertical section and the first slider 71, thereby fixing the first slide plate 3 to the base 1. Since the first linkage rod 5 connects the various first slide plates 3 to form a whole, fixing one of the first slide plates 3 can fix all the first slide plates 3 to the base 1.

[0096] When the size of the hopper 2 needs to be adjusted, loosening the first locking bolt allows all the first slide plates 3 to slide along the first horizontal direction on the base 1. When the first slide plates 3 have slid to the appropriate position, tightening the first locking bolt will fix all the first slide plates 3 back onto the base 1.

[0097] Based on the above structure, when a first locking component 7 is respectively provided between the two ends of one or more of the first slide plates 3 along the second horizontal direction and the base 1, each of the first sliders 71 on the same side is slidably disposed in the first T-groove 11 on the same side.

[0098] In some embodiments, a second locking assembly is provided between at least one second slide plate 4 and the base 1. The base 1 is provided with a second T-shaped groove extending along a first horizontal direction. The second locking assembly includes a second slider, a second fixing plate, and a second locking bolt, wherein: the second slider is slidably disposed in the second T-shaped groove; the first end of the second fixing plate is fixedly connected to the corresponding second slide plate 4, and the second end of the second fixing plate extends to the opening of the second T-shaped groove and is disposed opposite to the second slider; the second locking bolt passes through the second fixing plate and is screwed to the second slider, and the two sides of the opening of the second T-shaped groove are clamped between the second fixing plate and the second slider.

[0099] Figure 2 In the illustrated embodiment, a second T-shaped groove is provided on each of the two opposite outer surfaces of the base 1 along the second horizontal direction, and one of the second sliding plates 4 (specifically...) Figure 2 A second locking assembly is provided at both ends of the second horizontal direction (from bottom to top) between the base 1 and the base 1. The second locking assemblies at both ends of the second slide plate 4 correspond one-to-one with the two second T-slots. The structure of the second locking assembly is the same as that of the first locking assembly 7, and will not be described again here.

[0100] As an optional embodiment, the first T-slot 11 and the second T-slot located on the same outer surface are the same T-slot; or, the first T-slot 11 and the second T-slot located on the same outer surface are distributed in parallel and spaced apart. Preferably, the first T-slot 11 and the second T-slot located on the same outer surface are the same T-slot.

[0101] In some embodiments, to limit the sliding trajectory of the first slide plate 3 and the second slide plate 4 on the base 1, the base 1 further includes a slide plate guide rail. The slide plate guide rail is disposed on the rectangular frame 12 and extends along a first horizontal direction. Each of the first slide plates 3 and each of the slide plates 4 are slidably disposed on the slide plate guide rail by a slider. Further, referring to... Figure 2 , Figure 4 and Figure 5There are two skateboard guide rails, namely the first guide rail 14 and the second guide rail 15. The first guide rail 14 and the second guide rail 15 are respectively set on opposite sides of the rectangular frame 12 along the second horizontal direction. The two ends of each first skateboard 3 are respectively slidably set on the first guide rail 14 and the second guide rail 15 by sliders. The two ends of each second skateboard 4 are respectively slidably set on the first guide rail 14 and the second guide rail 15 by sliders.

[0102] Reference Figure 6 In some embodiments, a movable mounting base 101 is provided on the base 1 corresponding to the position of each fourth limiting structure 24, and a third locking assembly 8 is provided between each fourth limiting structure 24 and the base 1. The third locking assembly 8 includes a fixing member 81 and a movable member 82, wherein:

[0103] The fastener 81 is disposed on the base 1 and extends along the second horizontal direction. The fastener 81 has a plurality of limiting features distributed sequentially along the second horizontal direction.

[0104] The movable mounting base 101 is slidably mounted on the base 1 along the second horizontal direction. The fourth limiting structure 24 and the movable part 82 are both mounted on the corresponding movable mounting base 101. The movable part 82 can be locked or separated from any limiting feature on the fixed part 81.

[0105] In the above structure, when the movable part 82 is locked with one or more of the limiting features on the fixed part 81, the fourth limiting structure 24 is fixed to the base 1. When it is necessary to adjust the size of the hopper 2, the movable part 82 is controlled to separate from the limiting feature, and then the movable mounting base 101 and the fourth limiting structure 24 on it and the movable part 82 are pushed to slide synchronously along the second horizontal direction on the base 1; when the fourth limiting structure 24 slides to the appropriate position, the movable part 82 is controlled to lock with the limiting feature corresponding to that position, at which time the fourth limiting structure 24 is re-fixed to the base 1.

[0106] In some embodiments, the movable member 82 is slidably disposed on the corresponding movable mounting base 101 in a direction approaching or moving away from the fixed member 81. Based on the above structure, optionally, the fixed member 81 is a rack, the limiting feature is a tooth on the rack, and the movable member 82 is a rack, gear, or insert with a pointed tip; or, the limiting feature is a hole on the fixed member 81, and the movable member 82 is a plug rod, capable of being inserted into any one of the holes. Both of the above structures can achieve locking or disengagement between the movable member 82 and any limiting feature on the fixed member 81. Further, the third locking assembly 8 also includes an elastic member 83, with both ends of the elastic member 83 connected to the movable member 82 and the movable mounting base 101, respectively. The elastic member 83 can be one of a tension spring, a compression spring, and a torsion spring, configured to provide a spring force to drive the movable member 82 towards the fixed member 81, so that the movable member 82 automatically locks with the limiting feature on the fixed member 81 without external force.

[0107] In some other embodiments, the limiting feature is a threaded hole in the fixing member 81, and the movable member 82 is a screw rod that is rotatably mounted on the movable mounting base 101. The movable member 82 can be screwed into the threaded hole on any one of the fixing members 81. The above structure can also lock or separate the movable member 82 from any one of the limiting features on the fixing member 81.

[0108] Figure 6 In the illustrated embodiment, the fixing member 81 is a rack, and the movable member 82 is a pointed insert. The end of the movable member 82 facing the fixing member 81 has pointed teeth adapted to the rack. A return spring connects the movable member 82 and the movable mounting base 101. When no external force is applied, the pointed teeth at the bottom of the movable member 82 engage with the fixing member 81 under the drive of the return spring. When the position of the fourth limiting structure 24 needs to be adjusted, the movable member 82 is manually lifted to separate it from the fixing member 81. Then, the fourth limiting structure 24 is pushed to the appropriate position, and the movable member 82 is released. Under the drive of the return spring, the pointed teeth at the bottom of the movable member 82 contact and engage with the fixing member 81 again.

[0109] In some embodiments, in order to limit the sliding trajectory of the movable mounting base 101 on the base 1, the base 1 further includes a third guide rail 16. The number of third guide rails 16 is the same as that of the movable mounting bases 101 and they correspond one-to-one. The third guide rails 16 are disposed on the rectangular frame 12 and extend along the second horizontal direction. Each movable mounting base 101 is slidably disposed on the corresponding third guide rail 16 by a slider.

[0110] Figure 6In the embodiment shown, the movable mounting base 101 includes two columns 103, a base plate connected between the bottom ends of the two columns 103, and a limiting block 104 connected between the top ends of the two columns 103. The bottom of the base plate is provided with a slider adapted to the third guide rail 16. The two columns 103 are respectively fixedly connected to the two round rods of the corresponding fourth limiting structure 24 by bolts.

[0111] Continue to refer to Figure 3 At least one brush 9 is provided on the base 1 corresponding to the position of each storage area. Each brush 9 is located at the top edge of the corresponding storage area, and the bristles of each brush 9 can extend horizontally into the corresponding storage area. When the brush 9 is working normally, the bristles of the brush 9 are in a horizontal state and extend into the corresponding storage area; during the process of the top film being removed from the storage area, the brush 9 can prevent the film below from leaving the storage area with the film being removed.

[0112] Furthermore, a mounting seat is provided on the base 1 corresponding to the position of each brush 9, and each brush 9 is rotatably or slidably mounted on the corresponding mounting seat; the two extreme positions of the brush 9 before and after rotating or sliding relative to the corresponding mounting seat are the first position and the second position, respectively; when the brush 9 is in the first position, the bristles of the brush 9 extend horizontally into the corresponding storage area; when the brush 9 is in the second position, the entire brush 9 is located outside the corresponding storage area.

[0113] When brush 9 is working normally, it is in the first position. At this time, brush 9 can prevent the film below from leaving the storage area with the film that has been taken away. When the film in the storage area is used up, a new set of film needs to be added to the storage area from top to bottom. At this time, control brush 9 to rotate or slide relative to the corresponding mounting base, so that brush 9 moves to the second position. Since brush 9 in the second position is located outside the corresponding storage area, it will not obstruct the replenishment of film.

[0114] Reference Figures 6 to 8 In some embodiments, the mounting base includes a column 103 disposed on the base 1 and a limiting block 104 disposed on the top of the column 103. The limiting block 104 has a first limiting surface and a second limiting surface that are perpendicular to each other. A first magnet 105 is embedded on the first limiting surface and a second magnet 106 is embedded on the second limiting surface.

[0115] The brush 9 is rotatably mounted on the corresponding column 103; when the brush 9 rotates to the first position, the brush 9 abuts against the first limiting surface and is magnetically attracted to the first magnet 105; when the brush 9 rotates to the second position, the brush 9 abuts against the second limiting surface and is magnetically attracted to the second magnet 106.

[0116] In the illustrated embodiment, the mounting base includes two columns 103, and a limiting block 104 is fixed between the tops of the two columns 103. The brush 9 includes a rotating shaft 92 and a brush body 91 fixed on the rotating shaft 92. The two ends of the rotating shaft 92 are rotatably inserted into the two columns 103 around their own axes. When the brush 9 rotates to abut against the first limiting surface, the bristles of the brush 9 are in a horizontal state, and the first magnet 105 magnetically engages with the brush 9 to stably hold the brush 9 in this state. When the brush 9 rotates to abut against the second limiting surface, the bristles of the brush 9 are in a vertically downward state, and the second magnet 106 magnetically engages with the brush 9 to stably hold the brush 9 in this state.

[0117] Optionally, at least two of the first limiting structure 21, second limiting structure 22, third limiting structure 23, and fourth limiting structure 24 of each material bin 2 are respectively provided with a brush 9 on their top. Exemplarily, the top of each of the first and second limiting structures, or the first and third limiting structures, or the first, third, and fourth limiting structures, or each limiting structure, is respectively provided with a brush 9. This arrangement ensures that at least two sides of the top of each storage area are provided with a brush 9. During the process of removing the top film from the storage area, at least two sides of the top film need to be swept downwards by the brush 9, thereby ensuring that the lower film is not carried away by the top film.

[0118] Figure 3 In the embodiment shown, a brush 9 is provided on the top of the third limiting structure 23 and the fourth limiting structure 24 of each material box 2, that is, a brush 9 is provided on the top edges of the two opposite sides of each storage area along the second horizontal direction.

[0119] Furthermore, Figure 3 In the illustrated embodiment, the multiple mounting bases are of two types: a fixed mounting base 102 and a movable mounting base 101. The two types of mounting bases have the same structure but differ in their mounting method on the base 1. The fixed mounting base 102 is fixed to the base 1, while the movable mounting base 101 is slidably mounted on the base 1 along the second horizontal direction. Further, a fixed mounting base 102 is provided on the base 1 corresponding to the position of each third limiting structure 23, and each third limiting structure 23 and its top brush 9 are fixed to the corresponding fixed mounting base 102. Similarly, a movable mounting base 101 is provided on the base 1 corresponding to the position of each fourth limiting structure 24, and each fourth limiting structure 24 and its top brush 9 are fixed to the corresponding movable mounting base 101. Using this structure, when the fourth limiting structure 24 slides on the base 1, the brush 9 on the top of the fourth limiting structure 24 slides synchronously, thereby allowing the position of the brush 9 to adapt to films of different specifications.

[0120] In an embodiment where a brush 9 is respectively provided on the top of the first limiting structure 21 and the second limiting structure 22 of each material bin 2, a mounting seat is respectively provided on the base 1 corresponding to the position of each first limiting structure 21 and each second limiting structure 22. Each mounting seat is slidably disposed on the base 1 along a first horizontal direction. Each first limiting structure 21 and its top brush 9 are fixed to the corresponding mounting seat, and each second limiting structure 22 and its top brush 9 are fixed to the corresponding mounting seat. With the above structure, when the first limiting structure 21 and the second limiting structure 22 are controlled to slide on the base 1, the brushes 9 on their tops slide synchronously, thereby allowing the position of the brushes 9 to be adapted to films of different specifications.

[0121] For each embodiment where a brush 9 is provided on the top of the other two limiting structures of each material box 2, the structure is similar to the structure described above and will not be repeated here.

[0122] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
