[0002] With the popularization of office equipment such as scanners and shredders, the filing and destruction of some important documents are generally carried out as follows: the operator first uses a scanner to scan important documents, obtains digital file information and files it, and then uses a shredder to destroy the original documents.

Specific Embodiments

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0033] Accordingly, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0034] The following will describe in detail some embodiments of the present invention in conjunction with the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0035] The existing integrated scanning and shredding technology is mainly divided into two independent modules. That is, each page of the document needs to be completely scanned before entering the destruction program of the shredding module. When scanning, the shredder needs to wait, and the entire process is less efficient.

[0036] In view of this, the present invention provides an integrated scanning and shredding mechanism, which includes a paper pickup unit 100, a scanning unit 200, and a shredding unit 300; the paper passes through the paper pickup unit 100, the scanning unit 200, and the shredding unit 300 in sequence; the paper pickup unit 100 includes a separating roller 110 and a paper storage box 120, and the separating roller 110 rotates around its own axis to drive the paper in the paper storage box 120 to move; the scanning unit 200 is used to scan the paper; the shredding unit 300 includes shredding rollers 310, and the paper passes through between the two shredding rollers 310 that rotate around their own axes for shredding, and scanning the paper and shredding the paper are carried out synchronously.

[0037] The integrated scanning and shredding mechanism provided by the present invention realizes that the paper is shredded synchronously immediately after being scanned by the scanning unit 200 by arranging the shredding rollers 310 at the outlet of the scanning unit 200 and controlling the distance between the two, avoiding the waiting caused by the step-by-step scanning and shredding, improving the shredding efficiency, reducing the temporary storage space of the documents, and thus reducing the volume of the device.

[0038] The following will be combined with Figures 1-4 to describe in detail the structure and shape of the integrated scanning and shredding mechanism provided in this embodiment:

[0039] In an alternative embodiment of the present invention, the paper pickup unit 100 includes a separating roller 110, a paper storage box 120, a separating piece 130, a compression spring 140, and a paper pickup roller 150, as Figure 2 , Figure 3 , Figure 4 shown, Figure 2 , Figure 3 in which the double-dashed lines represent the paper. Among them, both the separating roller 110 and the paper pickup roller 150 rotate around their own axes, and the paper pickup roller 150 drives the paper to move out of the paper storage box 120 and pass through the separating roller 110 into the scanning unit 200.

[0040] In this embodiment, the pressing spring 140 is connected to the separating piece 130 and is used to apply a thrust force to the separating piece 130 so that the separating piece 130 clamps the paper with the separating roller 110, thereby enabling the separating roller 110 to drive the sorted paper to move. Specifically, the frictional force F1 between the separating roller 110 and the paper is greater than the frictional force F2 between the separating piece 130 and the paper, and the frictional force F2 between the separating piece 130 and the paper is greater than the frictional force F3 between the papers. By designing the frictional forces, it is ensured that the paper entering the scanning operation is a single sheet, that is, the frictional force (conveying force) of the separating roller 110 on the paper is greater than the frictional force (resistance) of the separating piece 130 on the paper, thereby ensuring and avoiding double feeding.

[0041] In this embodiment, the upward thrust force of the pressing spring 140 on the separating piece 130 is N, that is, the normal pressure. At this time,

[0042] F1 = N × μ1; F2 = N × μ2; F3 = N × μ3.

[0043] μ1, μ2, and μ3 are the friction coefficients between the separating roller 110 and the paper, between the separating piece 130 and the paper, and between the papers respectively.

[0044] F1 > F2 > F3.

[0045] In this embodiment, the paper storage box 120 includes a guide plate 121 and a bottom plate 122, and the included angle α between the guide plate 121 and the bottom plate 122 is an obtuse angle, as Figure 3 shown. Specifically, the paper is placed on the bottom plate 122 for storage. Along the paper moving direction, the end of the paper abuts against the guide plate 121 and slides along the guide plate 121 under the drive of the separating roller 110 and the paper pickup roller 150, and thus enters the scanning unit 200. That is, the paper climbs a slope when entering the separating roller 110, and the end of the paper is separated by the slope climbing and the blocking of the slope on the end of the paper, ensuring that only one piece of paper enters between the separating roller 110 and the separating piece 130.

[0046] In an alternative solution of this embodiment, the scanning unit 200 includes a scanning and reading roller 210, a photoelectric sensor 240, a contact image sensor 220, and a paper discharge roller 230, and the paper passes through the scanning and reading roller 210, the photoelectric sensor 240, the contact image sensor 220, and the paper discharge roller 230 in sequence. Among them, the contact image sensor 220 is used to trigger the contact image sensor 220.

[0047] In this embodiment, the scanning and reading roller 210 includes a driving reading roller 211 and a driven reading roller 212, and the paper discharging roller 230 includes a driving roller 231 and a driven roller 232. The driving reading roller 211 and the driving roller 231 rotate around their own axes to convey the paper, and at the same time, a set positive pressure is provided through the driven reading roller 212 and the driven roller 232 to ensure the conveyance of the paper; the paper passes between the driving reading roller 211 and the driven reading roller 212, and between the driving roller 231 and the driven roller 232, and the driven reading roller 212 and the driven roller 232 rotate driven by the paper.

[0048] In this embodiment, the scanning and shredding integrated mechanism further includes a processing unit, and the processing unit is used to obtain file information and archive and store the files.

[0049] The working process of the scanning and shredding integrated mechanism provided in this embodiment is as follows:

[0050] Place the original paper on the paper cassette 120, and the paper pickup roller 150 pushes the paper forward. Through the corner structure formed by the guide plate 121 under the paper path and the bottom plate 122, the separation of the head of the paper is completed, ensuring that only one piece of paper enters between the separation roller 110 and the separation piece 130 at a time. Subsequently, the original paper is separated through the cooperation of the separation roller 110 and the separation piece 130, and the paper enters the scanning unit 200 one by one for scanning, thus avoiding paper jams and missed scanning of files caused by multiple pieces of paper entering at one time.

[0051] Subsequently, the paper enters the scanning and reading roller 210. The frictional force of the scanning and reading roller 210 on the paper is greater than the frictional force F1 of the separation roller 110 on the paper. At this time, the paper moves at the linear speed of the scanning and reading roller 210. Driven by the scanning and reading roller 210, the paper passes through the photoelectric sensor 240 at a constant speed to trigger the contact image sensor 220, so that the contact image sensor 220 starts the scanning action. Then the paper enters the paper discharging roller 230. The frictional force of the paper discharging roller 230 on the paper is less than that of the scanning roller. Therefore, the paper still runs at a constant speed at the linear speed of the scanning roller, ensuring the uniform movement of the paper during the whole scanning process and improving the quality of the scanned image.

[0052] After the contact image sensor 220 obtains the content of the original document, it generates an electronic image and transmits it back to the processing unit for information recognition of two-dimensional codes and barcodes, and automatically generates a file name for the electronic image and saves it to the specified address.

[0053] Finally, the paper enters the shredding roller 310 to complete the destruction of the paper while completing the scanning.

[0054] When the processing unit acquires an image, it is necessary to preprocess the image, including denoising the image data and performing calibration processing. Median filtering is used to reduce noise when denoising the image data; calibration processing is performed on the image data to ensure the horizontal and vertical alignment of the image.

[0055] Subsequently, region segmentation is performed on the preprocessed image to locate the position of the QR code or barcode, and the QR decoding algorithm is used to parse the information in the QR code or the barcode decoding algorithm is used to parse the information in the barcode. According to the decoded information, a file name is generated according to the rules and the image data is bound to the file name, and then saved to the specified storage address. After the image data is successfully stored, a destruction instruction is sent to the hardware control module, and the hardware control module starts the shredding roller 310 and monitors the destruction process in real time to ensure that the paper is completely destroyed.

[0056] In addition, the processing unit stores the file information and the original data in the database and backs up the data regularly.

[0057] To ensure the uniform and stable speed of the paper during the scanning process, the conveying force speeds of each roller for the paper need to satisfy the following relationship:

[0058] The conveying forces of the scanning and reading roller 210, the paper discharging roller 230, the shredding roller 310, and the separating roller 110 for the paper decrease in sequence.

[0059] The conveying speeds of the shredding roller 310, the paper discharging roller 230, the scanning and reading roller 210, and the separating roller 110 are v1, v2, v3, and v4 respectively. v1>v2 = v3>v4.

[0060] The scanning and shredding integrated mechanism provided in this embodiment uses QR code or barcode recognition technology to identify the image data of the document original, realizing the automatic archiving of the scanned file while scanning the target file. At the same time, a high-precision paper conveying system is adopted to ensure that the paper does not vibrate due to the operation of the shredding roller 310 while being scanned at the contact image sensor 220, ensuring the scanning quality while completing the file destruction and improving the work efficiency.

[0061] It should be noted that the scanning and shredding integrated mechanism provided in this embodiment does not need to wait for a piece of paper to be scanned before shredding, and a piece of paper can be scanned and shredded simultaneously. That is, while shredding the front end of the paper, the back end is scanned.

[0062] The scanning and shredding integrated mechanism provided in this embodiment optimizes the coordination of the scanning and shredding actions, realizes the synchronous completion of actions such as scanning, archiving, and destroying the document original, improves the efficiency and enhances the confidentiality, and ensures that the file is instantly destroyed while being recognized and scanned.

[0063] Based on the scanning and shredding integrated mechanism provided in this embodiment, a scanner is proposed, which includes the above-mentioned scanning and shredding integrated mechanism.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
