Description

High-speed printer for printing stacking printing media Technical Field The utility model relates to the technical field of printers, in particular to a high-speed printer for printing stacked printing media. Background The printer for feeding paper in paper stacking mode is characterized by that several paper sheets (i.e. flat paper sheets) stacked on the paper feeding mechanism are separated from one another, and transferred to printing mechanism according to set direction, and then the printing mechanism can be used for making image-text printing. In a commercial or industrial printer (sheet-fed inkjet printer), it is generally necessary to internally perform duplex printing on an input sheet according to a set print job and then output the sheet, and to form a stack collection at a delivery mechanism, in order to ensure a printing speed. That is, in a high-speed printer for commercial or industrial use, the internal sequential conveyance path needs to meet the technical requirements for duplex printing of an input sheet without being output. Based on this, in the disclosed prior art, the solutions are mainly divided into three kinds as follows: Firstly, at the length direction both ends department of frame, respectively arrange paper feed mechanism and delivery mechanism, form the order conveying path that approximately straight style of calligraphy was arranged in the frame between paper feed mechanism and the delivery mechanism, arranged on the order conveying path and be close to the first printing mechanism of paper feed mechanism and be close to the second printing mechanism of delivery mechanism, arranged paper turn-over mechanism between first printing mechanism and the second printing mechanism. Obviously, the high-speed printer has the advantages of longer length, larger occupied area and higher technical requirements on the transportation space and the installation space. In other cases, the paper turning mechanism is arranged, so that the single paper output by the first printing mechanism needs to be turned over by the paper turning mechanism before entering the second printing mechanism, and the adjacent papers which are sequentially conveyed back and forth are necessarily required to have enough conveying intervals, so that the working efficiency of the printer is reduced, and meanwhile, the paper jam risk is increased by the turning mechanism working at high frequency. Secondly, at the two ends of the machine frame in the length direction, a paper feeding mechanism and a paper collecting mechanism are respectively arranged, a sequential conveying path with a complex rewinding structure is formed on the machine frame between the paper feeding mechanism and the paper collecting mechanism, a printing mechanism and a paper turning mechanism are arranged on the sequential conveying path, under the action of the paper turning mechanism, the sequential conveying path switches and rewinds the input paper, so that the same group of printing mechanisms can sequentially realize double-sided printing on the input paper, such as a double-sided color high-speed reciprocating type turnover single paper digital printer disclosed by Chinese patent literature, a technology disclosed by publication No. CN 115503356A and a technology disclosed by publication No. 2022, 12 months and 23 days, and the like. Such high speed printers, while advantageous in reducing the length dimension and footprint, reduce the technical requirements for shipping space and installation space. However, the paper turning mechanism is present, so that the single paper after the first printing needs to be turned over by the paper turning mechanism before entering the second printing, which inevitably affects the conveying efficiency of the single paper and is unfavorable for improving the working efficiency of the printer, and meanwhile, the paper jam risk is increased due to the existence of the turning mechanism. Thirdly, at the same end of the machine frame in the length direction, the paper feeding mechanism and the paper collecting mechanism are arranged together in an upper-lower structure mode, a U-shaped rewinding structure sequential conveying path is formed on the machine frame between the paper feeding mechanism and the paper collecting mechanism, a first printing mechanism close to the paper feeding mechanism and a second printing mechanism close to the paper collecting mechanism are arranged on the sequential conveying path in an upper-lower structure mode, a single paper guide conveying mechanism is arranged between the first printing mechanism and the second printing mechanism, under the action of the guide conveying mechanism, the U-shaped rewinding conveying is carried out on the input single paper by the sequential conveying path, so that the two groups of printing mechanisms can sequentially realize double-sided printing on the input single paper according to a set, for example, the technology disclosed in Chinese
