The outside of first metal strip 4 and the outer wall parallel and level of advance paper roller 2 avoid influencing the full laminating of advance paper roller 2 and paper.
The lower end of the sliding block 8 is provided with a groove 25, the air bag 32 is installed in the groove 25, the tail of the seal extends into the groove 25, the tail of the seal is in contact with the bottom of the groove 25, and the air bag 32 holds the neck of the seal tightly, so that the seal is held more firmly.
The air bag 32 is provided with an air inlet pipe 26 and an air outlet pipe 27, the air inlet pipe 26 is provided with an air inlet one-way valve 28, and the air outlet pipe 27 is provided with an air outlet switch valve 29.
The base 1 on be equipped with and be located the left board 30 of lifting of paper feed roller 2, lift the left end of board 30 and articulate on base 1 and articulated department installs second torsional spring 31, second torsional spring 31 makes and lifts the perk that makes progress of the right-hand member of board 30, lifts the right-hand member of file, reduces gradually along with the file, makes the file can contact with paper feed roller 2 all the time.
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 32, the air bag 32 is inflated through the air inlet pipe 26, the air bag 32 expands to hold the stamp tightly, a document to be stamped is stacked and arranged on the paper lifting plate 30, the right end of the document extends to the lower part of 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, at the moment, the two second electromagnets 22 are in an electrified state, the inkpad plate 20 is in a horizontal state and is positioned below the outer cylinder 7, the first torsion spring 21 is in a power storage state, and as no paper exists between the paper feeding roller 2 and the roller 3, the first metal strip 4 is communicated with the two second metal strips 5, the two first electromagnets 16 are also electrified, the two first electromagnets 16 attract each other to pull the conical block 14 backwards, the conical block 14 is separated from the conical groove 13, and at the moment, the incomplete gear 11 does not rotate.
After the paper feeding roller 2 is started, a first document is conveyed rightwards, the document enters between the paper feeding roller 2 and the roller 3, the document separates a first metal sheet from two second metal sheets, the two second metal sheets are in a disconnected state, the two first electromagnets 16 are powered off, the conical block 14 is pressed in the conical groove 13 under the action of a pressure spring, the driving pulley 17 drives the driven pulley 12 to rotate through a belt 18, the driven pulley 12 drives the incomplete gear 11 to rotate at the same angular speed as the paper feeding roller 2 under the action of friction force between the conical block 14 and the conical groove 13, when a toothed part of the incomplete gear 11 is meshed with the rack 10, the incomplete gear 11 drives the rack 10, the sliding block 8 and the stamp to move downwards under the action of the pressure spring, when the first document enters between the paper feeding roller 2 and the roller 3, the document is drawn out from the lower part of the stamp, and the stamp is finally pressed on the second document to stamp the second document, when the lower file is thick, the compression amount of the second compression spring 19 in the rack 10 is large, and when the lower file is thin, the compression amount of the second compression spring 19 in the rack 10 is small; in the process that the sliding block 8 moves downwards, a seal is firstly pressed on the mud printing plate 20, the deflector rod 24 on the sliding block 8 can move the switch 23 downwards, after the seal is compacted on the mud printing plate 20, the switch 23 is completely moved to the power-off position, the two second electromagnets 22 are powered off, the mud printing plate 20 rotates downwards to the vertical position under the action of the first torsion spring 21, and the seal continues to move downwards to be pressed on a file below to seal the file; when the incomplete gear 11 continues to rotate to be meshed with the rack 10, the sliding block 8 and the stamp return upwards under the action of the tension spring 9, in the process that the sliding block 8 moves upwards, the shift lever 24 shifts the switch 23 upwards to a switch-on position, the two second electromagnets 22 are electrified and attract each other, and the stamp mud plate 20 rotates upwards to a horizontal position under the action of the first torsion spring 21; the motion of the printing mud plate 20 is controlled through the stroke position of the sliding block 8, the printing mud plate 20 is automatically retracted after the sliding block 8 moves to a specific position, and the phenomenon that the sliding block 8 frequently and vigorously impacts the printing mud plate 20 to damage the printing mud plate 20 is avoided.
Since the seal portion is not sealed before the paper feed roller 2 feeds the first document, the first document can be sealed manually, 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, the second stamped file is conveyed rightwards by the paper feeding roller 2, when the incomplete gear 11 is meshed with the rack 10 again, the stamping part carries out stamping action again to stamp the next file, and when the incomplete gear 11 is meshed with the rack 10, the stamp retracts, and the automatic continuous stamping of the file is circularly carried out.
If the paper feeding roller 2 fails to feed paper and cannot convey the stamped documents, no document exists between the paper feeding roller 2 and the roller 3, the first metal strip 4 can connect the two second metal strips 5, the two first electromagnets 16 are electrified to attract each other to pull the conical block 14 to move backwards to separate the conical block 14 from the conical groove 13 under the action of the first pressure spring 15, at the moment, the transmission chain of the incomplete gear 11 is disconnected, the incomplete gear 11 does not rotate any more, and therefore the stamp cannot move downwards to stamp; after the paper feeding roller 2 recovers the normal paper feeding action, the file separates the first metal strip 4 from the second metal strip 5, the two first electromagnets 16 are powered off, the conical block 14 is tightly pressed in the conical groove 13 under the action of the first pressure spring 15, the incomplete gear 11 starts to rotate for stamping action, and if the paper feeding roller 2 can not recover the paper feeding action all the time, the machine needs to be stopped for inspection and maintenance.
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 through the on-off of the first metal strip 4 on the paper feeding roller 2 and the second metal strip 5 on the roller 3, when a paper feeding roller 2 cylinder fails to normally convey a document, a transmission chain of the stamping action is cut off, so that the document damage caused by repeated stamping on the same document can be avoided, the stamping action can be automatically started again after the paper feeding roller 2 recovers normal paper feeding, and the high reliability is ensured, and meanwhile, the capability of automatically connecting the stamping action after the paper feeding part is abnormally recovered due to occasional work is also realized; in addition, the flexible arrangement of the inkpad plate 20 enables the device to adapt to traditional stamps and atomic stamps, and the universality is strong.
