Fig. 10 is a flowchart of the method for automatic jet printing of electronic seal and logo according to the present invention. The invention relates to a spray printing method based on a device for automatic spray printing of an electronic seal and a mark, which comprises the following steps:

step S1, before printing the printed document by the printing unit 3, starting a third motor 3115 to enable a vertical stud 3116 to rotate so as to drive a threaded sleeve 3422 to drive a receiving plate 341 and a bottom plate 342 to descend, and at the moment, a plug 3412 descends so as to release the sealing of each nozzle;

With continued reference to fig. 1 to 10, in the present invention, when the printing unit 3 finishes printing a document, the interactive module controls the printing unit 3 to convey the document to the scanning binding unit 4 and controls the scanning binding unit 4 to collect image information of the printed document, and the interactive module determines whether the printing unit 3 is qualified for printing the document according to a longitudinal distance D between an actual position of a printed pattern in the document in the image information and an expected position of the printed pattern in the document set in the interactive module:

if the longitudinal distance D is smaller than or equal to a first preset longitudinal distance D1 set in the interaction module, the interaction module judges that the printing unit 3 is qualified for printing the file and judges that the printing unit 3 finishes printing the file, and the interaction module controls the printing unit 3 to print the next file;

If the longitudinal distance D is greater than the first preset longitudinal distance D1 and less than or equal to a second preset longitudinal distance D2 set in the interaction module, the interaction module determines that the printing unit 3 is not qualified for printing the document, the interaction module determines that the printing unit 3 finishes printing the document, controls the printing unit 3 to print the next document, and adjusts the rotation speed of the paper feeding lower roller 3222 to a corresponding value according to the difference value between the longitudinal distance D and the first preset longitudinal distance D1 when printing the next document;

if the longitudinal distance D is greater than the second preset longitudinal distance D2, the interaction module fast 13 determines that the printing unit 3 is not qualified for printing the document, and the interaction module determines that the printing unit 3 is not finished printing the document, sends out reprinting alarm, and adjusts the rotation speed of the paper feeding lower roller 3222 to a corresponding value according to the difference value between the longitudinal distance D and the second preset longitudinal distance D2 when reprinting;

the invention can effectively ensure the printing precision of the file by detecting the printing position of the file and rapidly completing the adjustment or reprinting of the transmission speed of the next file when the printing position does not accord with the expected, and simultaneously can effectively stop printing and reprint the file when the deviation between the actual printing position and the expected printing position is overlarge, thereby effectively improving the printing efficiency of the device for automatic spray printing of the electronic seal and the mark while further improving the printing precision of the file.

Specifically, when the longitudinal distance D is greater than the first preset longitudinal distance D1 and less than or equal to the second preset longitudinal distance D2, the interaction module calculates a difference between the longitudinal distance D and the first preset longitudinal distance D1 and marks the difference as a corrected difference Δda, and sets Δda=d-D1, and the interaction module adjusts the rotation speed of the paper feeding lower roller 3222 to a corresponding value when the printing unit 3 prints the next document according to the corrected difference Δda:

if the correction difference value delta Da is smaller than or equal to a first preset correction difference value delta Da1 set in the interaction module, the interaction module uses a first preset rotation speed correction coefficient alpha 1 to adjust the rotation speed of the paper feeding lower roller 3222 when conveying the next file to a corresponding value, wherein 1 is smaller than alpha 1 and smaller than 1.2;

if the correction difference value Δda is greater than the first preset correction difference value Δda1 and less than or equal to a second preset correction difference value Δda2 set in the interaction module, the interaction module uses a second preset rotation speed correction coefficient α2 to adjust the rotation speed of the paper feeding lower roller 3222 when conveying the next file to a corresponding value, wherein Δda2 > - Δda1, and 1.2 < α2 < 1.5;

if the correction difference Δda is greater than the second preset correction difference Δda2, the interaction module uses a third preset rotation speed correction coefficient α3 to adjust the rotation speed of the paper feeding lower roller 3222 when the next document is conveyed to a corresponding value, wherein α3 is greater than 1.5 and less than 1.7;

When the interactive module uses the i-th preset correction coefficient αi to adjust the rotation speed of the paper feeding roller 3222 when conveying the next document to a corresponding value, i=1, 2 is set, if the printing position is close to the paper feeding roller set 322 side relative to the expected position, the adjusted rotation speed W '=w×αi is set, and if the printing position is close to the paper discharging roller set 323 side relative to the expected position, the adjusted rotation speed W' =w× (2- αi) is set.

According to the invention, the difference between the longitudinal distance and the first preset longitudinal distance is calculated, and the rotation speed of the paper feeding lower roller 3222 for conveying the next file is adjusted in a targeted manner according to the difference, so that the file can be quickly conveyed to the corresponding position while the file conveying time length is ensured, and the printing precision of the device for automatic electronic seal and mark spraying for the file is effectively improved, and the printing efficiency of the device for automatic electronic seal and mark spraying for the file is further improved.

Specifically, when the interactive module completes the adjustment of the rotation speed of the paper feeding lower roller 3222, the interactive module controls the jet printing unit 3 to jet print the next document and controls the scanning binding unit 4 to collect the image information of the printed document after jet printing to determine the actual position of the printed pattern of the document, and determines whether the printing of the jet printing unit 3 for the document is qualified according to the longitudinal distance D' between the actual position and the corresponding expected position,

If the longitudinal distance D' is smaller than or equal to a first preset longitudinal distance D1 set in the interaction module, the interaction module judges that the printing unit 3 is qualified for printing the file and judges that the printing unit 3 finishes printing the file, and the interaction module controls the printing unit 3 to print the next file;

if the longitudinal distance D 'is greater than the first preset longitudinal distance D1 and less than or equal to a second preset longitudinal distance D2 set in the interaction module, the interaction module determines that the printing unit 3 is not qualified for printing the document, the interaction module determines that the printing unit 3 finishes printing the document, controls the printing unit 3 to print the next document, and adjusts the rotation speed of the paper feeding lower roller 3222 to a corresponding value according to the difference value between the longitudinal distance D' and the first preset longitudinal distance D1 when printing the next document;

if the longitudinal distance D 'is greater than the second preset longitudinal distance D2, the interaction module fast 13 determines that the printing unit 3 is failed in printing and failure of the document is failed in document conveying stability, the interaction module marks the corrected rotation time length as t when the lower paper feeding roller 3222 conveys the next document, and t meets t×w' ∈l1, L2, where L1 is a first critical standard and L2 is a second critical standard.

The invention further determines the specific reasons of disqualification of the printing position for the position of the printing pattern in the follow-up file, and adjusts the rotation time of the lower paper feeding roller 3222 to the corresponding value when judging the reason is the conveying stability, so that the stability of the lower paper feeding roller 3222 in the file conveying process can be effectively improved, and the printing efficiency of the device for automatic printing of the electronic seal and the mark for the file is further improved while the printing precision of the device for automatic printing of the electronic seal and the mark for the file is further improved.
