However, current copying and printing are no longer limited to printing and copying of small standard paper. There is often a demand for copying larger non-standard paper. However, it is not easy to prepare non-standard paper (because the required length of the paper is difficult to determine). The width can only be set to several commonly used widths, but the length needs to be cut at any time during printing. However, the most convenient way to store long raw paper before use is to roll it together, which is easy to affect the copying effect when entering the copier, and it is easy to get a paper jam.

[0021] In some embodiments of the utility model, the frame 1 is divided into two layers, the upper and lower layers are provided with double-layer paperboards 31 of different specifications, and the upper roller 35 and the lower roller 35 can slide up and down in the upper and lower layers. A support seat 30 is provided in the lower layer, and a double-layer paperboard 31 is provided on the support seat 30. The height of the double-layer paperboard 31 is adjustable, and the double-layer paperboard 31 is adjustable in the paper feeding direction; a support frame 32 is fixed on the support seat 30, and a slide bar 33 is provided on the support frame 32. A cutting knife 34 that can slide along the slide bar 33 is provided on the slide bar 33, and the direction of the slide bar 33 is perpendicular to the paper feeding direction, and the cutting knife 34 is flush with the paper discharge end of the double-layer paperboard 31 in the vertical direction; a paper feed roller is provided at the front end of the double-layer paperboard 31, and the paper feed roller includes an upper roller 35 and a lower roller 35, and the upper roller 35 and the lower roller 35 are driven by a motor to rotate synchronously, and the paper discharge end of the paper feed roller is flush with the interlayer of the double-layer paperboard 31.
[0022] In some embodiments of the present invention, the upper layer and the lower layer share a vertical slide bar, and the upper roller 25 and the lower roller 35 are slidably arranged on the vertical slide bar. It should be understood here that the upper and lower layers of the clipboard have the same structure but different sizes. In order to accommodate papers of different widths, the upper roller and the lower roller can be shared and only need to be adjusted up and down to reach the appropriate position.
[0023] In some embodiments of the present invention, a standby layer 4 is provided at the bottom of the frame 1, and a plurality of upper rollers 25 and lower rollers 35 are stored in the standby layer. It should be understood that the structures of the upper rollers and the lower rollers are the same, and the widths are also fixed. After the width of the paper is determined, the effect close to the paper width can be achieved by increasing or decreasing the number of upper rollers and lower rollers.
[0024] In some embodiments of the present invention, a universal wheel 5 is disposed at the bottom of the frame 1 .
[0025] In some embodiments of the present invention, the cutter 24 is provided with a controller connected to the copier signal, which is used to control the cutter 24 to cut the paper after the copier completes copying.
[0026] Working principle:
[0027] When in use, first determine which layer of the clipboard to use according to the size of the paper, then pass the paper into the clipboard, then install the upper and lower rollers and adjust them up and down until the tangent of the upper and lower rollers is level with the sandwich part of the clipboard, then start the motor to drive the upper and lower rollers to rotate, and the paper is squeezed through the clipboard and enters the copier. The upper and lower rollers and the clipboard can be used to flatten the paper and then enter the copier. After copying is completed, the cutter starts to cut the paper to obtain a long printed product. Although there is some blank space at the end of the printed product, this is acceptable relative to the length of the printed product. Of course, if you do not want to have such a blank space, you can set the cutter at the exit of the copier, or cut after printing is completed. This does not affect the core issue of this application in solving the problem of long printed paper.
[0028] The extended paper printing device for a copier provided by the utility model can be directly connected to the front end of the copier when in use, and the paper can be automatically cut after the copying is completed. Before the copier feeds the paper, the device successively rolls and flattens the paper with a plate clamp, thereby greatly improving the effect of roll paper copying.
[0029] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
