[0028] Reference Figures 1 to 4 The double-action paper storage device of the present invention is provided in the following embodiments:

[0029] A double-action paper storage device includes a first paper storage rack 200, a second paper storage rack 300 and a driving mechanism 400.

[0030] The connecting direction of the first paper storage rack 200 and the second paper storage rack 300 is a first direction. The first paper storage rack 200 and the second paper storage rack 300 are both slidably arranged along the first direction.

[0031] The driving mechanism 400 is used to drive the first paper storage rack 200 and the second paper storage rack 300 to move toward or away from each other in a first direction. When one of the first paper storage rack 200 and the second paper storage rack 300 moves in the forward direction of the first direction, the other moves in the reverse direction of the first direction.

[0032] The first paper storage rack 200 is provided with a first roller assembly 210, and the second paper storage rack 300 is provided with a second roller assembly 310. The first roller assembly 210 includes a first paper storage roller 211, and the second roller assembly 310 includes a second paper storage roller 311. The axes of the first and second paper storage rollers 211 and 311 are arranged parallel to each other. The first and second paper storage rollers 211 and 311 are respectively arranged to rotate around their respective axes on the first and second paper storage racks 200 and 300.

[0033] In actual use, paper sequentially passes around the first and second paper storage rollers 211, 311. The drive mechanism 400 can drive the first and second paper storage racks 200, 300 toward or away from each other, thereby storing or releasing paper by varying the spacing between the first and second paper storage rollers 211, 311. The first and second paper storage racks 200, 300 can move synchronously in opposite directions along the line connecting them, significantly accelerating paper loading and unloading, meeting the demand for high-speed paper storage and unloading.

[0034] In this embodiment, the dual-action paper storage device further includes a base frame 100. The first paper storage rack 200 and the second paper storage rack 300 are arranged in a front-to-rear arrangement and are both slidably connected to the base frame 100 in the front-to-rear direction. The base frame 100 provides mounting support and sliding guidance for the first paper storage rack 200 and the second paper storage rack 300, enabling them to move synchronously in the front-to-rear direction.

[0035] The first paper storage rack 200 and the second paper storage rack 300 are both arranged to slide horizontally in the front-to-back direction, and can transfer the weight of the first paper storage rack 200 and the second paper storage rack 300 and the weight of the first roller group 210 and the second roller group 310 to the base frame 100, thereby reducing the driving load of the driving mechanism 400, improving the moving speed and start-stop speed of the two paper storage racks, and thus improving the paper storage and response speed.

[0036] To improve space utilization at the production site, the dual-action paper storage device of this embodiment is an elevated structure. The base frame 100 includes an upper frame 110 and a lower frame 120. The upper frame 110 and the lower frame 120 are arranged one above the other, with the lower frame 120 located below the upper frame 110. The upper end of the lower frame 120 is fixedly connected to the lower side of the upper frame 110, and the lower end of the lower frame 120 is fixedly connected to the ground. The upper frame 110 is in the shape of a rectangular parallelepiped frame. The first paper storage rack 200 and the second paper storage rack 300 are both located above the upper frame 110.

[0037] In order to adapt to the high-speed paper storage and unloading, the paper storage capacity of the paper storage device needs to increase.

[0038] In this embodiment, there are multiple first rollers and multiple second roller groups 310. Multiple first rollers are arranged vertically and spaced apart on the first paper storage rack 200. Multiple second roller groups 310 are arranged vertically and spaced apart on the second paper storage rack 300. During actual use, paper passes through each of the first rollers and the second roller group 310 in sequence, thereby forming multiple paper paths between the first paper storage rack 200 and the second paper storage rack 300.

[0039] In a further embodiment, each first roller assembly 210 includes multiple first paper storage rollers 211, and each second roller assembly 310 includes multiple second paper storage rollers 311. The multiple first paper storage rollers 211 in each first roller assembly 210 are arranged in a front-to-back direction. The multiple second paper storage rollers 311 in each second roller assembly 310 are also arranged in a front-to-back direction. This arrangement of multiple paper storage rollers allows paper to be fed multiple times between the first paper storage rack 200 and the second paper storage rack 300, significantly increasing paper storage capacity.

[0040] Furthermore, to prevent friction between multiple rolls of paper, the paper towels of each first paper storage roller 211 in the first roller assembly 210 of this embodiment are not consistent. The diameters of the multiple first paper storage rollers 211 in each first roller assembly 210 are arranged in descending order toward the second roller assembly 310. Similarly, the diameters of the multiple second paper storage rollers 311 in each second roller assembly 310 are arranged in descending order toward the first roller assembly 210.

[0041] That is, in the front-to-back direction, a first paper storage roller 211 with a smaller diameter is closer to the second roller group 310, while a first paper storage roller 211 with a larger diameter is further away from the second roller group 310. Similarly, a second paper storage roller 311 with a smaller diameter is closer to the first roller group 210, while a second paper storage roller 311 with a larger diameter is further away from the first roller group 210.

[0042] In actual use, between the first roller group 210 and the second roller group 310, which are arranged in a front-to-back arrangement, the inner paper feed is formed between the first paper storage roller 211 and the second paper storage roller 311, which have the smallest diameters. The second paper feed is formed between the first paper storage roller 211 and the second paper storage roller 311, which have the larger diameters. Similarly, the outermost paper feed is formed between the first paper storage roller 211 and the second paper storage roller 311, which have the largest diameters. This technical solution prevents paper from being worn out during multiple feeds due to the different diameters of the paper storage rollers, thus preventing wear and tear on the paper and affecting its quality.

[0043] Referring to the accompanying drawings, in this embodiment, there are three first roller groups 210, arranged vertically. Each first roller group 210 includes three first paper storage rollers 211 arranged in a front-to-rear arrangement and having different diameters. There are two second roller groups 310, arranged vertically. Each second roller group 310 includes three second paper storage rollers 311 arranged in a front-to-rear arrangement and having different diameters.

[0044] In this embodiment, the first paper storage rack 200 includes two first side panels 220 and a plurality of first paper storage rollers 211. The left and right ends of each first paper storage roller 211 are rotatably connected to the two first side panels 220. The plurality of first paper storage rollers 211 are connected to the two first side panels 220 to form the first paper storage rack 200. Similarly, the second paper storage rack 300 includes two second side panels 320 and a plurality of second paper storage rollers 311. The left and right ends of each second paper storage roller 311 are rotatably connected to the two second side panels 320 to form the second paper storage rack 300.

[0045] Both the first side panel 220 and the second side panel 320 are flat. It is worth noting that, in this embodiment, both first side panels 220 are provided with a paper coil avoidance groove 221. The paper coil avoidance groove 221 opens toward the second paper storage rack 300. In the front-to-back projection, the first paper storage rack 200 is positioned between the two second side panels 320. The second roller assembly 310 is aligned front-to-back with the paper coil avoidance groove 221.

[0046] When the first and second paper accumulators 200 and 300 move toward each other to their limit positions, the second roller assembly 310 can be inserted into the paper loop avoidance groove 221, allowing the second paper storage rollers 311 to be offset from the corresponding first paper storage rollers 211. This allows paper to pass directly between the first and second paper storage rollers 211 and 311 in the vertical direction, achieving paper threading. Subsequently, when the first and second paper accumulators 200 and 300 move away from each other, paper can be tensioned and stored between the first and second paper storage rollers 211 and 311.

[0047] The driving mechanism 400 is connected to the first paper storage rack 200 and the second paper storage rack 300 respectively, and enables the first paper storage rack 200 and the second paper storage rack 300 to move closer to each other or farther away from each other in the front-to-back direction.

[0048] In this embodiment, the drive mechanism 400 includes a drive motor 410 and a transmission component. The transmission component includes a synchronous belt 420 and two synchronous pulleys 430. The two synchronous pulleys 430 are rotatably disposed at the front and rear ends of the base frame 100. The output shaft of the drive motor 410 is in transmission connection with one of the synchronous pulleys 430. The synchronous belt 420 is driven around the two synchronous pulleys 430. The rotation axes of the two synchronous pulleys 430 extend in the left-right direction, so that the synchronous belt 420 has upper and lower belt surfaces that are parallel to each other and extend in the front-to-back direction. The first and second paper storage racks 200 and 300 are fixedly connected to the upper and lower belt surfaces, respectively. When the driving motor 410 drives the synchronous pulley 430 to rotate, it can drive the synchronous belt 420 to move along its path, and the upper belt surface and the lower belt surface move in opposite directions in the front-to-back direction, thereby causing the first paper storage rack 200 and the second paper storage rack 300 to move in opposite directions, thereby achieving the first paper storage rack 200 and the second paper storage rack 300 to move closer to each other or away from each other.

[0049] To ensure uniform force distribution between the first and second paper storage racks 200 and 300, transmission components in this embodiment are provided in pairs on the left and right sides of the upper end of the base frame 100. Referring to the accompanying drawings, the two transmission components are connected to the left and right ends of the first and second paper storage racks 200 and 300, respectively. The synchronous pulleys 430 of the two transmission components are coaxially fixedly connected to each other in a one-to-one correspondence.

[0050] In other embodiments, the transmission member may be a double-threaded screw. The axial direction of the double-threaded screw extends in the front-to-back direction and is rotatably connected to the base. The drive motor 410 is drivably connected to the double-threaded screw. The front half and the rear half of the double-threaded screw have external threads with opposite rotation directions. The first paper storage rack 200 and the second paper storage rack 300 are respectively threadedly connected to the front half and the rear half of the double-threaded screw. When the drive motor 410 drives the double-threaded screw to rotate, the first paper storage rack 200 and the second paper storage rack 300 move in opposite directions under the action of the reverse thread transmission, thereby achieving approaching each other or moving away from each other.
