Description

Vertical conveying device for single printing medium and high-speed printer Technical Field The utility model relates to the technical field of printers, in particular to a vertical conveying device for single printing medium and a high-speed printer comprising the vertical conveying device. Background In the design structure of the printer, a feeding mechanism (paper feeding mechanism) for providing printing media and a receiving mechanism (paper receiving mechanism) for collecting the printing media are arranged, a sequential conveying path for feeding and receiving single printing media is formed between the feeding mechanism and the receiving mechanism, and the printing mechanism for printing corresponding image-text information on the current printing media conveyed is arranged on the sequential conveying path. In order to make the design of the printer compact and reduce the occupied area, the sequential conveying path in the printer generally makes reasonable use of space in the height direction of the printer, which is most prominent especially in commercial or industrial high-speed printers (i.e., sheet-fed ink-jet printers) with large structural volumes. The sequential transport path of the printer is typically formed with a wrap-around configuration along the height direction, such that the print media forms a bottom-up/top-down wrap-around transport path (especially bottom-up wrap-around transport paths are most common). In this way, the sequential conveyance path of the printer involves a height switching conveyance (or climbing conveyance) in the height direction rewinding conveyance of the single printing medium. In the prior art disclosed, the height conversion conveyance of a single printing medium in the height direction is mainly performed by a plurality of sets of paper feed rollers arranged at intervals along a conveyance path (for example, the technology disclosed in chinese patent literature is referred to as "a duplex inkjet printing apparatus", the technology disclosed by CN 109968830A, the technology disclosed by 2019, month 05, etc.), or by a plurality of sets of paper feed rollers arranged at intervals in combination with conveyance paths provided along a conveyance path (for example, the technology disclosed in chinese patent literature is referred to as "a duplex printer", the technology disclosed by CN 119689814A, the technology disclosed by 2025, month 25, etc.). However, it is difficult to perform high-speed switching conveyance of a single sheet of printing medium by a paper feed driving roller, and it is difficult to perform vertical conveyance in which the direction of conveyance of the printing medium is sharply changed at the downstream end of the flat conveyance mechanism, and the conveyance of the printing medium is interrupted by forming a conveyance jam with the higher the direction of conveyance, and it is necessary to perform gentle conveyance in which the direction of conveyance is changed. Therefore, a common structural form is to arrange a plurality of groups of paper feeding driving rollers at a distance similar to a C-shaped arc track in the height direction, that is, the conveyed printing medium is conveyed in a height direction in a height conversion manner by a C-shaped track, for example, the technology of publication nos. CN 109968830A and CN 119689814A. Obviously, the sequential conveying path for carrying out height conversion conveying in the height direction by the C-shaped track needs to occupy a larger arrangement space, which is not beneficial to the compact structure of the formed printer. In addition, since the paper feeding driving roller conveys the entering printing medium in an extrusion mode of the rotary friction of the roller, the printing medium is easy to be extruded and deformed in the rotary friction, so that on one hand, the conveying blockage risk is increased, especially, the paper which is printed, thinner and has high ink coverage rate is easy to be blocked in the high-speed conveying process, namely, the paper is not suitable for high-speed conveying (namely, high-speed conveying is generally more than 60 sheets/min), and on the other hand, the flatness of the conveyed printing medium is affected, so that the printing quality of the printer on the printing medium is not good. In view of the above, in order to make the printer compact, and to improve the printing medium conveying efficiency and printing quality, it is necessary to optimally design a height-shift conveying structure for conveying a single printing medium in the height direction, which is more necessary for a high-speed printer (single sheet inkjet printer) for commercial or industrial use. Disclosure of utility model The technical aim of the utility model is to provide a single printing medium vertical conveying device which is beneficial to the compactness of the printer structure, the improvement of the printing medium conveying efficiency and the reduction of t
