[0033] The following is a detailed description of the embodiments. These embodiments are merely illustrative and are not intended to limit the scope of protection of this invention. The same / similar symbols are used to denote the same / similar components in the following description. Directional terms mentioned in the following embodiments, such as up, down, left, right, front, or back, are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0034] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 This diagram shows a schematic representation of the structure of a transaction machine 100 when it is not turned on, according to an embodiment of the present invention. Figure 2 It shows Figure 1 A schematic diagram of the transaction machine 100 in the open state. Figure 3 A schematic diagram of a paper conveying device 110 according to an embodiment of the present invention is shown. Figure 4 A perspective view and a partial enlarged view of a paper conveying device 110 according to an embodiment of the present invention are shown.

[0035] According to one embodiment of the present invention, the paper conveying device 110 can be used in a paper machine 100 or a paper machine 100 with an automatic paper feed device, or in equipment such as a printer, scanner, fax machine, or copier. The paper conveying device 110 includes one or more rotatable feed rollers 120, which can contact and rotate with documents to convey documents. However, after prolonged use, excessive paper dust accumulates on the surface of the feed rollers 120, resulting in reduced friction and affecting the paper feeding function of the paper conveying device 110.

[0036] Please refer to Figure 2 The office machine 100 includes an input tray 102, an output tray 104, and a paper conveying device 110 located inside the machine body 106. The input tray 102 is located on one side of the office machine 100 and is used to stack multiple documents, which can be sequentially conveyed into the office machine 100 via the input tray 102. Please refer to... Figure 3 The paper conveying device 110 may include a drive wheel 112, a feed wheel 120, and a cleaning unit 130. The machine body 106 has a conveying channel 103 (as shown by the arrow) located between the drive wheel 112 and the feed wheel 120. The drive wheel 112 is disposed on one side (e.g., the upper side) of the feed wheel 120, and the feed wheel 120 is located between the cleaning unit 130 and the drive wheel 112. The drive wheel 112 and the feed wheel 120 are used to clamp and rotate documents to move them.

[0037] The drive wheel 112 is, for example, a driving wheel (e.g., a plastic wheel) that can be rotated by a motor. The feed wheel 120 is, for example, a driven wheel (e.g., a rubber wheel) located below the drive wheel 112 for moving the document. Alternatively, in another embodiment, the drive wheel 112 is located below the feed wheel 120, and the present invention is not limited thereto.

[0038] Furthermore, the cleaning element 130 is disposed on one side of the feed roller 120, meaning that the cleaning element 130 and the drive wheel 112 are located on opposite sides of the feed roller 120. The cleaning element 130 has a fibrous and porous structure, and it has a pressure-resistant and wear-resistant friction surface 132, allowing the cleaning element 130 to make close and comprehensive contact with the feed roller 120 for cleaning. The aforementioned pressure-resistant surface refers to the cleaning element 130 having a dense structure, small pores, and high density. The cleaning element 130 can be manufactured according to pressure resistance requirements, making the friction surface 132 of the cleaning element 130 less prone to deformation. For example, wool felt with a high-density surface and paper scrap filling space can be manufactured by stamping, resulting in good cleaning effect. The aforementioned wear-resistant surface refers to the cleaning element 130 having a soft and fine texture, a fibrous and porous structure 134, and high wear resistance, which allows it to easily carry away small media (such as paper scraps or dust) from the surface of the feed roller 120 without damaging or scratching it. For example, soft wool is used as the surface layer of the cleaning part 130 because wool has both softness and toughness, good fiber elasticity, can be completely molded in one piece, and has good resilience. After the wool felt product is folded, it can quickly return to its original shape and is not easily deformed. In addition, its fiber structure can be tightly intertwined, which can prevent the paper feed roller 120 from being damaged when scraping paper scraps. The wool felt will also wear down when it comes into contact with the paper feed roller 120. The outermost wool surface layer will fall off after wear, but the inner layer after the wool falls off will be exposed as a new wool surface layer to continue contact cleaning.

[0039] According to the above description, the cleaning component 130 can be a felt wheel, such as a wool felt wheel, horsehair wheel, or plush wheel. Other similar wool materials, natural wool, or artificial wool are also acceptable. In addition, the cleaning component 130 can also be a cloth wheel, leather wheel, or cotton wheel. As long as the material is soft and the stamping density is controlled, a porous structure 134 can be naturally formed to provide space for paper scraps or dust to fill the gaps, thus enabling contact cleaning of the paper feed wheel 120.

[0040] In another embodiment, the cleaning element 130 is, for example, a wool polishing wheel, a nylon polishing wheel, or a flat nonwoven wheel, having a fibrous and porous structure and high abrasion resistance, and can easily bring into the surface of the paper wheel 120 a small amount of media (such as paper scraps or dust).

[0041] Additionally, please refer to Figure 4To prevent excessive paper scraps from adhering to the surface of the feed roller 120, at least one scraping groove 122 may be provided on the surface of the feed roller 120. The scraping groove 122 can increase paper gripping force, reduce noise, remove paper scraps, and promote uniform wear. The scraping groove 122 is generally parallel to the axial direction of the feed roller 120 to serve as an area for filling paper scraps.

[0042] Please refer to Figure 4 , Figures 5A-5B ,in Figure 5A and Figure 5B Enlarged schematic diagrams of the cleaning element 130 and its friction surface 132 according to an embodiment of the present invention are shown respectively. The friction surface 132 of the cleaning element 130 is in close contact with the feed roller 120. The cleaning element 130 can also generate an upward elastic force through an elastic structure (e.g., a spring or sheet) to ensure close contact between the friction surface 132 of the cleaning element 130 and the feed roller 120. Simultaneously, the upward elastic force increases friction and improves the cleaning effect of the feed roller 120. Furthermore, the paper conveying device 110 may also include a bracket 140 disposed below the feed roller 120. The cleaning element 130 is fixedly disposed on the bracket and contacts the surface of the feed roller 120. When the feed roller 120 rotates, the cleaning element 130 can simultaneously clean the surface of the feed roller 120. In another embodiment, the bracket 140 has a receiving groove 141 and two slots 142. The cleaning component 130 is disposed in the receiving groove 141, and each end of the cleaning component 130 is provided with a rotating shaft 133, with each rotating shaft 133 located in a corresponding slot 142. Therefore, the cleaning component 130 can be fixedly disposed below the paper feed roller 120 by the bracket 140 and rotate around the rotating shaft 133.

[0043] exist Figure 5A and Figure 5B In this embodiment, the cleaning component 130 has, for example, a wheel 131 that rotates around a pivot 133. Wool felt or other materials with fibrous and porous structures cover the outer surface of the wheel 131 to carry away minute media from the surface of the paper feed roller 120. However, the cleaning component 130 in this embodiment is not limited to a wheel 131; it can also be a board with wool or a column with an arcuate surface, as long as it can be placed within the space of the bracket 140. The aforementioned arcuate surface contacts the surface of the paper feed roller 120, but it can also contact the surface of the paper feed roller 120 in a flat plane; this invention does not limit this. Furthermore, the cleaning component 130 in this embodiment is manufactured using a stamping process to create a high-density surface layer of fibers and porous structures 134. Compared to cleaning brush heads such as bristle brushes or nylon brushes, it has greater pressure resistance and does not suffer from problems such as deformation and elastic aging after being flattened, similar to brush heads. Therefore, it is more durable and does not damage the paper feed roller 120. Furthermore, the cleaning component 130 in this embodiment has a high-density surface layer of fibers, which can provide a larger contact area and improve the cleaning effect of the paper feed roller 120.

[0044] The paper feeding device described in the above embodiments of the present invention can be applied to automatic paper feeders, office machines, printers, scanners, fax machines, copiers, and other equipment to prevent excessive micro-media from adhering to the paper feed rollers, which would reduce friction and cause paper feeding failure. The cleaning components are made of cleaning materials such as wool felt rollers, horsehair rollers, plush rollers, cloth rollers, leather rollers, cotton rollers, wool polishing rollers, nylon polishing rollers, or flat non-woven fabric rollers. This embodiment utilizes the surface characteristics of wool felt rollers, etc., to add a set of cleaning components near the original paper feed roller position to scrape off the paper debris adhering to the surface of the paper feed roller. Compared to brushes or cleaning brush heads, wool felt rollers, etc., have a better cleaning effect and do not damage the paper feed rollers, providing a longer lifespan for the paper feed rollers. This prevents paper debris from filling the grooves and causing paper feeding failure, and the wear of the wool felt rollers themselves provides a self-cleaning effect; their naturally formed holes can serve as filling areas for paper debris, quickly removing it.

[0045] In summary, the embodiments provided above are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
