[0003] Chinese Patent Publication No. CN113478992A discloses a fully automatic high-speed batch stamping machine, comprising a housing, a workbench, a stamping unit, a paper feed mechanism, a paper collection mechanism, and a central control processor. The present invention provides a visual detector and a pressure sensor at the bottom of the official seal holder. Upon completion of a single stamping operation, the central control processor controls the visual detector to detect the stamping trace and adjusts the stamping pressure of the Z-axis motion mechanism during subsequent stamping operations based on the clarity of the stamping trace. This effectively improves the clarity of the stamping trace on the document after stamping, thereby increasing the number of valid documents in a batch of stamped documents. Furthermore, the present invention can quickly determine the cause of the unclear stamping trace and quickly address it based on the relationship between the adjusted pressure and a preset pressure threshold, as well as the ink content, thereby effectively improving the stamping efficiency of the fully automatic high-speed batch stamping machine for documents to be stamped.

[0121] Example 2

[0122] This embodiment 2 is based on the high-speed batch stamping machine with automatic paper feeding and automatic page turning and outputting, and is further provided with a central control module, which is respectively connected to the automatic paper feeding module, the stamping module and the automatic page turning and outputting module, and is used to adjust the translation motor speed to a corresponding value according to the time it takes for a single paper to completely enter the printing platform, and to determine whether to adjust the paper jam risk value to a corresponding paper jam risk value according to the difference between the actual thickness of the document to be printed and the preset document thickness, and to adjust the power motor speed to a corresponding power motor speed value according to the difference between the actual paper output quantity per unit time and the preset paper output quantity.

[0123] Please continue reading Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 As shown, the central control module determines whether the adjustment angle of the flower wheel is reasonable according to the time T when a single paper completely enters the printing platform under the preset first condition, wherein the central control module is provided with a preset first time T1 and a preset second time T2, wherein T1<T2,

[0124] If T≤T1, the central control module determines that the rotation angle of the transmission unit is lower than the allowable range, controls the visual detector 2 to detect the thickness of the paper, and calculates the thickness quantity ratio according to the thickness of the paper to adjust the paper jam risk value to the corresponding value;

[0125] If T1<T≤T2, the central control module determines that the adjustment angle of the pattern wheel is lower than the allowable range, calculates the difference ΔT between the time it takes for a single paper to completely enter the printing platform and the preset time, and adjusts the translation motor speed to the first translation motor speed value according to ΔT, setting ΔT=T-T1;

[0126] If T>T2, the central control module determines that the adjustment angle of the flower wheel is within the allowable range and controls each module to continue to perform the corresponding operation of stamping the document to be stamped according to the predetermined operating parameters.

[0127] This embodiment sets a preset first time length and a preset second time length and determines whether the adjustment angle of the pattern wheel is reasonable by comparing the time length for a single paper to completely enter the printing platform with the preset time length. This embodiment can accurately determine the cause of the time length for the paper to completely enter the printing platform not meeting the requirements, namely, incorrect adjustment of the tension of the paper feed board 22 and incorrect pressing of the document to be printed. This reduces the impact of inaccurate tension of the paper feed board 22 and inaccurate pressing of the document to be printed on the printing speed and printing stability, thereby achieving improved printing efficiency and printing stability.

[0128] Please continue reading Figure 3 As shown, the central control module adjusts the translation motor speed to the first corresponding translation motor speed value V' according to the difference △T between the time when a single paper completely enters the printing platform and the preset time under the preset first time condition, and sets V'=V0×αi, αi is the translation motor speed adjustment coefficient, and i=1, 2. The central control module is provided with a preset first time difference △T1, a preset second time difference △T2, a preset first translation motor speed adjustment coefficient α1, a preset second translation motor speed adjustment coefficient α2, and a preset translation motor speed V0, wherein △T1<△T2, 1<α1<α2,

[0129] If ΔT≤ΔT1, the central control module determines to adjust the rotation speed of the translation motor to V0;

[0130] If ΔT1<ΔT≤ΔT2, the central control module determines to use α1 to adjust the speed of the translation motor;

[0131] If ΔT>ΔT2, the central control module determines to use α2 to adjust the speed of the translation motor;

[0132] The preset first time condition is that the central control module completes the determination of whether the adjustment angle of the flower wheel is reasonable and the time T for a single paper to completely enter the printing platform satisfies T1<T≤T2.

[0133] Furthermore, this embodiment sets a preset first time difference, a preset second time difference, a preset first translation motor speed adjustment coefficient, a preset second translation motor speed adjustment coefficient and a preset translation motor speed. By adjusting the translation motor speed to the first corresponding translation motor speed value according to the difference between the time it takes for a single paper to completely enter the printing platform and the preset time under the preset first time condition, the impact of inaccurate compression of the document to be printed due to inadequate adjustment of the flower wheel in the paper feeding module on the printing efficiency is reduced, thereby further achieving improvement in printing efficiency and printing stability.

[0134] Please continue reading Figure 2 As shown, the central control module determines whether a wheel device failure occurs based on the comparison result of the difference between the time it takes for a single paper to completely enter the printing platform and the preset time and the preset maximum time difference under the preset first time condition, wherein the central control module is provided with a preset maximum time difference △Tmax.

[0135] If △≤△Tmax, the central control module determines that the wheel is not faulty;

[0136] If △>△Tmax, the central control module determines that the wheel is faulty and issues a wheel maintenance notice.
