The stamping part can be slidably arranged on the base 1, and the position of the stamping part can be adjusted according to the stamping position of the file.
When the stamping device is used, the tail part of a stamp extends into the air bag 12, the air bag 12 is inflated through the air inlet pipe 23, the air bag 12 expands to hold the stamp tightly, a document to be stamped is stacked and arranged on the paper lifting plate 27, the right end of the document extends to the position below the paper feeding roller 2, the power supply of the stamping device is started, the paper feeding roller 2 is driven by the motor to rotate, all electromagnets are in a connected state at the moment, the sliding block 9 is positioned at the top of the outer cylinder 8 under the action of suction force of the first electromagnet 10, the pressure spring 11 is in a compressed state, the second electromagnet 18 and the third electromagnet 19 attract each other, the stamping plate 16 is positioned below the outer cylinder 8 in a horizontal state, and the first torsion spring 17 is in a force storage state.
When the paper feeding roller 2 is started, the front end of the paper feeding arc section is contacted with the right end of a document, the friction paste 3 of the paper feeding arc section conveys the document rightwards, the document enters between the paper feeding roller 2 and the roller 4, the document separates a first metal sheet from two second metal sheets, the two second metal sheets are in a disconnected state, the paper feeding roller 2 continues to rotate, a pressure lever 15 at the end part of an idle rotation arc section firstly presses a first switch 14 at the front, a first electromagnet 10 is powered off, a sliding block 9 drives a stamp to pop up downwards under the action of a pressure spring 11, the lower end of the stamp is contacted and tightly pressed with a stamp mud plate 16 to coat the stamp with dye, in the process, a deflector rod 21 on the sliding block 9 downwards stirs the second switch 20, the second switch 20 is completely stired to a power-off position after the stamp is coated with the dye, the second electromagnet 18 and a third electromagnet 19 are powered off, and the stamp mud plate 16 downwards rotates to a vertical position under the action of a first torsion spring 17, the seal is continuously moved downwards and pressed on the lower file, and the file is sealed; when the pressing rod 15 rotates continuously along with the paper feeding roller 2 until the pressing rod 15 presses down the first switch 14 behind, the first electromagnet 10 is electrified, the first electromagnet 10 adsorbs the sliding block 9 to enable the sliding block 9 to move upwards to retract into the outer cylinder 8 under the action of the pressing spring 11, in the process that the sliding block 9 moves upwards, the deflector rod 21 shifts the second switch 20 upwards to a switch-on position, the second electromagnet 18 and the third electromagnet 19 are electrified to attract each other, and the mud printing plate 16 rotates upwards to a horizontal position under the action of the first torsion spring 17; the motion of the mud printing plate 16 is controlled through the stroke position of the sliding block 9, the mud printing plate 16 is automatically retracted after the sliding block 9 moves to a specific position, and the situation that the mud printing plate 16 is damaged due to the fact that the sliding block 9 frequently and strongly impacts the mud printing plate 16 is avoided.
Since the seal portion does not perform the seal operation when the paper feed roller 2 conveys the first document, the first document can be manually sealed, or a blank sheet can be placed on the top of the document when the documents are stacked.
And (3) as the paper feeding roller 2 continues to rotate, when the friction paste 3 of the paper feeding arc section contacts with the next document again, the stamped document is conveyed rightwards, when the pressing rod 15 presses the front first switch 14 again, the stamping part carries out stamping action again to stamp the next document, when the pressing rod 15 presses the rear first switch 14, the stamp retracts, and the automatic continuous stamping of the document is circularly carried out.
If the paper feeding roller 2 fails to feed paper and cannot convey the stamped files, no file exists between the paper feeding roller 2 and the roller 4, the first metal strip 5 can connect the two second metal strips 6, the first electromagnet 10 is electrified, and when the pressing rod 15 presses the first switch 14, the first electromagnet 10 cannot be powered off, so that the sliding block 9 cannot move downwards to stamp, and the phenomenon that the same file is stamped repeatedly to damage the file is avoided; if the paper feeding roller 2 can smoothly convey the document away in the next cycle, the pressing rod 15 can trigger the stamping action to continue stamping when pressing the first switch 14, and if the paper feeding roller 2 fails to convey the document away in several cycles, the machine needs to be stopped for inspection and maintenance.
It should be noted that when the pressing rod 15 presses the following first switch 14, the paper feeding arc is still engaged with the roller 4, so as to avoid that when the document is not conveyed normally, in the period after the preceding first switch 14 is pressed and before the following second switch 20 is pressed, the paper feeding arc is engaged with the roller 4 to disconnect the two second metal strips 6, and the first electromagnet 10 is powered off to execute the stamping action.
The invention utilizes the insulativity of the paper to monitor, and can reliably work for paper files of any material, thickness, color and the like.
According to the invention, the stamping action of the stamping part is controlled by the on-off of the first metal strip 5 on the paper feeding roller 2 and the second metal strip 6 on the roller 4 in cooperation with the two first switches 14, when a paper feeding roller 2 cannot normally convey a file, the stamping action is locked, so that the file damage caused by repeated stamping on the same file can be avoided, and if the paper feeding roller 2 circularly recovers normal paper feeding, the stamping action can be automatically started again, so that the high reliability is ensured, and meanwhile, the capability of automatically connecting the stamping action after the paper feeding part is occasionally abnormally recovered is achieved; in addition, the flexible arrangement of the mud printing plate 16 enables the device to adapt to traditional stamps and atomic stamps, and the universality is strong.
