The upper roller 110 has two ends provided with conveying rollers 111, and the lower roller 120 has two ends provided with separating rollers 121, wherein the conveying rollers 111 and the separating rollers 121 have different rotating directions, the conveying rollers 111 can convey paper documents to the paper output side, and the separating rollers 121 can return the paper documents to the paper input side. The paper document enters from the paper inlet side between the upper roller 110 and the lower roller 120, and is discharged from the paper outlet side between the upper roller 110 and the lower roller 120 by the conveying roller 111 and the separation roller 121. When a plurality of paper documents enter between the upper roller 110 and the lower roller 120 at the same time, the transport roller 111 contacts the uppermost paper document and transports the uppermost paper document to the paper discharge side, thereby achieving the effect of separating the single paper. When a plurality of paper documents are stacked, the rest of the paper documents move to the paper outlet side along with the paper document at the uppermost end, and the separation roller 121 of the lower roller 120 contacts with the bottoms of the rest of the paper documents to return the rest of the paper documents to the paper inlet side. Since the friction force between the conveying roller 111 and the paper document is greater than the friction force between the separating roller 121 and the paper document, the uppermost paper document can overcome the acting force of the separating roller 121 with the help of the conveying roller 111, and can be smoothly moved to the paper discharging side, and the remaining paper documents, except the uppermost paper document, are withdrawn from the paper feeding side by the action of the separating roller 121. Therefore, the upper roller 110 and the lower roller 120 are engaged with each other, so that highly precise paper separation can be achieved, and the paper separation effect can be improved.

In addition, the conveying rollers 111 are disposed at both ends of the upper roller 110, and the separating rollers 121 are disposed at both ends of the lower roller 120, so that the conveying rollers 111 and the separating rollers 121 are in contact with only edges of the paper documents, and compared to the related art in which a compression roller is used for separating and conveying, the conveying rollers 111 and the separating rollers 121 can reduce contact areas with the paper documents, thereby preventing the conveying rollers 111 and the separating rollers 121 from being in contact with pigments, paints, handwriting, or other materials on the surfaces of the paper documents, preventing the conveying rollers 111, the separating rollers 121, and the paper documents from being contaminated, improving durability of the paper separating mechanism 100, and improving paper feeding quality.

It should be noted that a plurality of friction particles may be distributed on the outer surface of the conveying roller 111 and the separating roller 121, wherein the friction particles distributed on the outer surface of the conveying roller 111 are more than the friction particles distributed on the outer surface of the separating roller 121, so that the friction force between the conveying roller 111 and the paper document is greater than the friction force between the separating roller 121 and the paper document. In addition, the width of the conveying roller 111 may be larger than that of the separating roller 121, so that the contact area of the conveying roller 111 and the paper document is larger than that of the separating roller 121 and the paper document, and the friction force between the conveying roller 111 and the paper document is larger than that between the separating roller 121 and the paper document.

With reference to fig. 2, it should be noted that a connecting member 132 may be disposed between the supporting plates 131 on two sides, the connecting member 132 may improve stability and durability of the supporting assembly 130, and meanwhile, the connecting member 132 may be a baffle 150 with a larger width, so that the baffle 150 may shield the upper roller 110 and the lower roller 120, prevent external foreign objects from entering the paper separating mechanism 100 to cause paper jam, and improve durability and stability of the paper separating mechanism 100.

In addition, the guide plate 140 extends upward to the separation roller 121, the guide plate 140 can support and move the paper document to the separation roller 121, and meanwhile, paper jamming caused by downward movement of the paper document after passing through the conveying roller 111 is avoided, so that the bottom of the paper document can be acted by the force of the separation roller 121 under the guiding action of the guide plate 140, and redundant paper documents can be returned, thereby realizing high-precision paper separation, avoiding paper jamming and improving the durability of the paper separation mechanism 100.

It can be understood that, the baffles 150 are further disposed on two sides of the supporting assembly 130, the baffles 150 can prevent the paper document from shifting, and have a guiding function, so that the paper document is prevented from being skewed in the process of passing through the conveying roller 111 and the separating roller 121, and a paper jam is prevented, so that the paper document can smoothly and neatly enter between the upper roller 110 and the lower roller 120, thereby improving the paper separating efficiency and improving the paper feeding effect.

In addition, the paper output platform 160 is located above the lower roller 120, so that the bottom of the paper document contacts with the separation roller 121, the redundant paper document is returned, and the paper separation effect is improved.

It can be understood that the lower roller 120 is provided with the paper out sensor 170 near the paper out side, the paper document moves to the paper out side under the action of the conveying roller 111, when the paper document moves to the paper out sensor 170, it is considered that the paper separating operation is completed, the conveying roller 111 and the separating roller 121 stop rotating, and after the paper document is prevented from being separated from the contact with the conveying roller 111, the paper document is prevented from moving under the action of the separating roller 121 and being difficult to take paper, or a paper jam occurs, and the paper feeding effect is improved.

It can be understood that the paper separating mechanism 100 is further provided with an adjusting component 180, the adjusting component 180 is located at one side of the supporting component 130, and the adjusting component 180 can rotate the supporting component 130, so that the supporting component 130 rotates with the lower roller 120 as an axis, thereby driving the upper roller 110 to move. Therefore, when the paper separating mechanism 100 separates paper documents with paint, coating, handwriting or other materials, the position of the upper roller 110 can be adjusted by the adjusting assembly 180, so that the contact between the upper roller 110 and the surface of the paper documents is reduced, the upper roller 110 and the paper documents are prevented from being polluted, and the paper feeding effect is improved.

With reference to fig. 3, it can be understood that the paper separating mechanism 100 further includes a lifting assembly 190, the lifting assembly 190 is located at the paper feeding side of the upper roller 110, and the lifting assembly 190 can feed the paper documents to the upper roller 110, so that the topmost paper document is in contact with the conveying roller 111, thereby facilitating separation of the topmost paper document, and the paper separating efficiency is improved without manual paper feeding.

It can be understood that the lifting assembly 190 further includes a travel switch 191, the travel switch 191 can limit the height of the lifting assembly 190 for conveying the paper documents, when the paper documents trigger the travel switch 191, the lifting assembly 190 stops conveying the paper documents, the height of the paper documents is maintained, the problem that the paper documents at the uppermost end exceed the upper roller 110 and cannot be separated is avoided, and the paper separating effect is improved.

It can be understood that the diameter length of the separation roller 121 is greater than the diameter length of the conveying roller 111, and since the paper document is easy to tilt up after passing through the conveying roller 111, the large-sized separation roller 121 can be fully contacted with the bottom surface of the paper document, which avoids that the paper document cannot be separated due to tilting, and improves the accuracy of document separation.
