The certificate is sent from the automatic page turning mechanism 300 to the printing mechanism 500 for printing, and then sent from the printing mechanism 500 to the automatic page turning mechanism 300 for page turning. After page turning, the other side of the certificate is printed and then sent to the stamping mechanism 600 for stamping. After stamping, the certificate is issued.

[0039] like Figure 2As shown, the automatic page turning mechanism 300 includes an automatic certificate lifting component 310, which is used to convey the stacked unprinted certificates upward; a certificate suction component 340, which is arranged above the automatic lifting component 310, and is used to suck the certificates conveyed upward by the automatic lifting component 310 and move the certificates along the front-to-back direction; an automatic page turning component 370, which is arranged in front of the moving direction of the certificate suction component 340, and receives the certificates transmitted by the certificate suction component 340 and transmits the certificates to the printing device before turning the pages of the certificates; an auxiliary page turning component 400, which turns the certificates during the process of the automatic page turning component turning the pages of the certificates.

[0040] The automatic lifting component 310 includes a lifting base 311, a lifting support plate 312 fixedly arranged on the left and right sides of the lifting base 311, and a lifting transmission member 314 arranged on the lifting support plate 312. The lifting transmission member 314 can be a synchronous belt transmission member, a sprocket transmission member, a ball screw transmission member, etc. A paper support platform 320 is connected to the lifting transmission member 314, and the paper support platform 320 is lifted and lowered by the lifting transmission member 314.

[0041] The certificates are stacked on the paper support 320. The certificates stacked on the paper support 320 are taken away one by one, and the lifting transmission member 314 drives the paper support 320 to rise continuously, thereby realizing the automatic lifting of the certificates.

[0042] A first through-beam light sensor 332 is embedded on the lifting support plate 312. The receiving end and the transmitting end of the first through-beam light sensor 332 are respectively arranged on the lifting support plate 312 on both sides, and are used to sense the height at which the certificates are stacked. When the certificates are lifted to the height, a signal is sent to the control system to execute corresponding instructions.

[0043] like Figure 3 , Figure 4As shown, the certificate suction component 340 includes: a suction support plate 341 fixedly arranged at the upper end of the lifting support plate 312, a suction connection plate 342 slidably connected to the suction support plate 341 on one side (lower surface) facing the automatic lifting component 310, the suction connection plate 342 slides in the front-to-back direction, a suction power member 343 for moving the suction connection plate 342 is arranged, and a vacuum suction cup 347 fixedly arranged on the suction connection plate 342 in the vertical direction, the vacuum suction cup 347 is used to suck the certificate, and two vacuum suction cups 347 are arranged, and the two vacuum suction cups 347 are respectively located at the left and right ends of the suction support plate 341. The vacuum suction cup 347 sucks the certificate, and the suction connection plate 342 is driven to move in the front-to-back direction by the suction power member 343, and the sucked certificate can be sent to the automatic page turning component 370 to realize the certificate transmission and automatic page turning.

[0044] The adsorption power member 343 includes an adsorption motor 344 fixedly arranged on the adsorption connecting plate 342 in the vertical direction. The adsorption motor 344 is arranged in the vertical direction. The output shaft of the adsorption motor 344 passes through the adsorption connecting plate 342, an adsorption gear 345 fixedly connected to the output shaft of the adsorption motor 344, and an adsorption rack 346 meshing with the adsorption gear 345. The adsorption rack 346 extends in the front-to-back direction and is fixed on the lower surface of the adsorption support plate 341. The adsorption motor 344 generates power to drive the adsorption gear 345 to transmit, thereby causing the adsorption gear 345 to move along the extension direction of the adsorption rack 346.

[0045] An adsorption guide 348 for directional movement of the adsorption connecting plate 342 is provided between the adsorption support plate 341 and the adsorption connecting plate 342. The adsorption guide 348 includes an adsorption guide rail 349, which is fixedly provided on the adsorption support plate 341 along the front-rear direction, and a slide 350 matched on the adsorption guide rail 349, and the slide 350 is fixedly connected to the adsorption connecting plate 342. The adsorption guide 348 is used to stably connect the adsorption connecting plate 342 and the adsorption support plate 341, so that the adsorption support plate 341 moves along the front-rear direction below the adsorption connecting plate 342.

[0046] A paper pressing plate 351 is fixedly connected to the side (front side) of the adsorption connecting plate 342 facing the automatic page turning component 370. The paper pressing plate 351 is used to press down the front end of the absorbed certificate so that the certificate has a certain downward inclination angle at one end close to the automatic page turning component 370 and is inserted into the automatic page turning component 370, thereby realizing smoother transportation and automatic page turning.

[0047] A travel sensor 352 is fixedly disposed on one surface (lower surface) of the suction support plate 341 facing the automatic lifting assembly 310 . The travel sensor 352 is used to limit the moving travel of the adsorption connecting plate 342 .

[0048] A micro vacuum pump 357 is fixedly arranged on the upper surface of the suction support plate 341. The micro vacuum pump 357 adopts a S370D3-VP vacuum pump. The vacuum pump is connected to a suction pipe, and the other end of the suction pipe is connected to the vacuum suction cup 347. The micro vacuum pump 357 provides negative pressure to the vacuum suction cup 347, so that the vacuum suction cup 347 generates suction force, thereby sucking the certificate.

[0049] A through slot is provided on the suction support plate 341, and a wire plate 358 is fixedly connected to the upper surface of the adsorption connecting plate 342. The wire plate 358 passes through the through slot, and the suction tube and the cable for controlling the adsorption motor 344 are fixed on the wire plate 358 and pass through the through slot, which facilitates the installation of various parts.

[0050] like Figure 5 As shown, the automatic page turning component 370 includes paper guide support plates 371 located on the left and right sides, the paper guide support plates 371 are fixedly set on the upper part of the front surface of the lifting support plate 312, an upper paper guide roller 372 set on the paper guide support plate 371 is rotated through a bearing, a page turning motor 373 drives the upper paper guide roller 372 to rotate, a lower paper guide roller 374 is located below the upper paper guide roller 372 and abuts against the upper paper guide roller 372, one end of the lower paper guide roller 374 is provided with a locking component 375, and a pushing component 376 for intermittently moving the lower paper guide roller 374 downward to release the certificate between the upper paper guide roller 372 and the lower paper guide roller 374.

[0051] The page turning motor 373 is fixedly arranged on the paper guide support plate 371 on one side, and the output shaft of the page turning motor 373 is fixedly connected to the paper guide main gear 377. The paper guide main gear 377 is meshed with a paper guide sub gear 378. The paper guide sub gear 378 is fixedly connected to the upper paper guide roller 372 and drives the upper paper guide roller 372 to rotate.

[0052] like Figure 5 , Figure 6As shown, both ends of the lower paper guide roller 374 are connected with push-down blocks 379 through bearings, and a guide groove 380 is extended in the up and down directions on the paper guide support plate 371, and the push-down block 379 is embedded in the guide groove 380 and can move up and down, and a guide column 381 is provided on the lower bottom of the guide groove 380, and the push-down block 379 is sleeved on the guide column 381 through the hole provided, and moves in a directional manner along the guide column 381. In order to make the lower paper guide roller 374 abut against the upper paper guide roller 372, a first spring is sleeved on the guide column 381, and one end of the first spring abuts against the lower bottom surface of the guide groove 380 and the other end abuts against the lower surface of the push-down block 379, and the elastic force of the first spring realizes that the lower paper guide roller 374 and the upper paper guide roller 372 abut against each other to press the certificate.

[0053] The push-down component 376 includes a push-down motor 383 fixedly arranged at the lower part of the paper guide support plate 371, and a push-down rotating rod 384 connected to the push-down motor 383 through a push-down gear. The push-down rotating rod 384 is rotatably arranged on the paper guide support plates 371 on both sides through bearings. Both ends of the push-down rotating rod 384 pass through the paper guide support plate 371, and eccentric wheels 385 are fixedly arranged on both ends of the push-down rotating rod 384 respectively. A downward bearing 386 is provided below the eccentric wheel 385 and is equipped with the eccentric wheel 385. A downward plate 399 is connected to the downward bearing 386. A space avoidance groove 387 is opened on the downward plate 399. The push-down rotating rod 384 is located in the space avoidance groove 387, and the upper end of the downward plate 399 is fixedly connected to the push-down block 379. When the push-down motor 383 rotates, the push-down rotating rod 384 rotates, thereby driving the eccentric wheels 385 on both sides to rotate, and the eccentric action of the eccentric wheels 385 pushes the downward bearing 386 downward, and the downward bearing 386 drives the downward plate 399 to move downward, so that the push-down block 379 moves downward and compresses the first spring, so that the upper paper guide roller 372 and the lower paper guide roller 374 are separated. The eccentric wheel 385 continues to rotate, so that the push-down block 379 returns upward due to the action of the first spring, so that the upper paper guide roller 372 and the lower paper guide roller 374 continue to abut against each other, and the certificate is transmitted.

[0054] The end of the push-down rotating rod 384 is fixedly connected with a counting sensor piece 388, and one side of the paper guide support plate 371 is fixedly provided with a first counting sensor 389 and a second counting sensor 390 along the front-to-back direction. The counting sensor piece 388 is sensed by the first counting sensor 389 when it rotates half a circle, and is sensed by the second counting sensor 390 when it rotates the other half a circle.

[0055] like Figure 7As shown, the locking component 375 includes a coil support 391 fixedly arranged on the paper guide support plate 371, an electromagnetic coil 392 fixedly arranged on the coil support 391, and an iron core 393 sleeved in the electromagnetic coil 392. The iron core 393 is arranged in the front-to-back direction. A friction connection frame 394 is fixedly arranged at the end of the iron core 393. A friction plate 395 is fixedly arranged in the friction connection frame 394. A friction wheel 396 is fixedly connected to the end of the lower paper guide roller 374. After the electromagnetic coil 392 is energized, it drives the iron core 393 to move so that the friction plate 395 abuts against and presses the friction wheel 396. Thus, the lower paper guide roller 374 can be quickly locked and braked. A slide rail guide is directly arranged on the lower surface of the friction plate and the coil support 391, so that the friction plate 395 can move stably in the front-to-back direction. The locking component used in this embodiment is different from that in the prior art. In this embodiment, locking is achieved by contacting the outer circular contour of the friction wheel 396 through the friction plate 395, thereby increasing the friction force, strengthening the braking force, and braking quickly.

[0056] A second certificate sensor 397 is provided at the end close to the printing mechanism, i.e., the paper output end of the automatic page turning component 370, and a first certificate sensor 398 is provided at the paper input end of the automatic page turning component 370. The sensor is used to recognize the certificate and automatically control the automatic page turning printing.

[0057] like Figure 5 , Figure 8As shown, the working principle of the automatic page turning component 370 is as follows: the top certificate that is sucked is fed between the upper paper guide roller 372 and the lower paper guide roller 374. The top certificate consists of an upper certificate page 11 and a lower certificate page 12. The printing requirement is to print the upper surface of the upper certificate page, then turn over the upper certificate page 11, and print the lower surface of the upper certificate page 11 and the upper surface of the lower certificate page 12. When the top certificate is fed between the upper paper guide roller 372 and the lower paper guide roller 374, the first lifting motor 313 drives the unsucked certificate to descend, and at the same time, the page turning motor 373 drives the upper paper guide roller 372 and the lower paper guide roller 374 to rotate together to receive the sent certificate, and wait until the second certificate sensor 397 detects the presence of a certificate. The travel sensor 352 also receives a sensing signal, which causes the adsorption motor 344 and the vacuum suction cup 347 to rotate. The work stops, and the certificate is sent to the printing mechanism 500 at the rear for printing under the rotation of the upper paper guide roller 372 and the lower paper guide roller 374. At the same time, the push-down motor 383 drives the eccentric wheel 385 to rotate, and the eccentric wheel 385 pushes the lower bearing 386 downward, and the lower bearing 386 drives the lower plate 399 to move downward, and the lower plate 399 drives the lower paper guide roller 374 to move downward, so that the upper paper guide roller 372 and the lower paper guide roller 374 are separated, so that the printer will not be affected by the resistance of the upper and lower paper guide rollers 374 The printing mechanism 500 prints, and after detecting the certificate, the printing mechanism 500 starts to print the first side content. After the first side content is printed, the printing mechanism 500 returns the certificate. During the certificate returning process of the printing mechanism 500, when the second certificate sensor 397 detects the certificate again, the push-down motor 383 drives the eccentric wheel 385 to make the upper and lower paper guide rollers 374 contact and rotate together. The upper paper guide roller 372 and the lower paper guide roller 374 start to reverse under the drive of the page turning motor 373 to receive the certificate returned by the printer 520. During the process of returning the certificate, when the first certificate sensor 398 just detects the certificate, the page turning motor 373 stops rotating, and the locking component 375 starts to work so that the lower paper guide roller 374 cannot rotate. Then the page turning motor 373 starts to reverse, so that the paper in contact with the upper paper guide roller 372 moves backward along with the upper paper guide roller 372, while the paper in contact with the lower paper guide roller 374 is fixed by the lower paper guide roller 374. In this way, the upper certificate page 11 of the certificate appears to be bulged in the middle (such as Figure 8 -a), since the friction coefficient between the upper paper guide roller 372 and the lower paper guide roller 374 and the document is greater than the friction coefficient between the papers inside the document, the upper certificate page 11 in contact with the lower paper guide roller 374 will be locked together with the lower paper guide roller 374, and the lower certificate page 12 in contact with the upper paper guide roller 372 will move backwards together with the upper paper guide roller 372, and the effect of the paper formation is as follows: Figure 8Then the locking part 375 is released, and the page turning motor 373 drives the upper paper guide roller 372 and the lower paper guide roller 374 to move backward together, and the upper paper guide roller 372 and the lower paper guide roller 374 also drive the upper and lower pages to move backward together, and when the upper page moves to the end and leaves the upper paper guide roller 372 (such as Figure 8 -b, 8-c), when the upper certificate page 11 in contact with the upper paper guide roller 372 is completely separated from the upper paper guide roller 372, the page turning motor 373 delivers the certificate into the printing mechanism 500 (such as Figure 8 -d), at this time, the upper certificate page and the lower certificate page sent into the printing mechanism 500 have been spread out, when the second certificate sensor 397 detects the presence of paper, the push-down motor 383 starts to work to disengage the upper paper guide roller 372 and the lower paper guide roller 374, and then the printing mechanism 500 prints the lower surface of the upper certificate page 11 and the upper surface of the lower certificate page 12, after the second page is printed, the printer 520 sends the certificate into the stamping mechanism 600 for stamping.

[0058] like Figure 2 , Figure 5 As shown, the auxiliary page turning component 400 includes a first paper pushing rod 410 located at the paper feeding end of the automatic page turning component 370 and below the suction component, the first paper pushing rod 410 is retracted in the left-right direction and moves in the front-back direction, the first paper pushing rod 410 moves in the front-back direction and turns the paper, a push rod support 426 which is sleeved outside the first paper pushing rod and has an electromagnetic coil, and an auxiliary power unit 420 which is fixedly connected to the push rod support 426 and pushes the push rod support 426 to move.

[0059] The auxiliary power unit 420 includes an auxiliary bracket 421 that slides on the lifting support plate 312 in the front-back direction, an auxiliary motor 422 that is fixedly arranged on the auxiliary bracket 421 in the vertical direction, an auxiliary gear 423 that is fixedly connected to the output shaft of the auxiliary motor 422, and an auxiliary rack 424 that is fixedly arranged on the lifting support plate 312 in the length direction, and the auxiliary gear 423 is meshed with the auxiliary rack 424. The auxiliary bracket 421 is fixedly connected to a push rod support plate 425, and a push rod support seat 426 is connected to the push rod support plate 425. The first paper push rod 410 is inserted and slidably moved in the electromagnetic coil in the push rod support seat 426. The first paper push rod 410 can be moved in the push rod support seat 426 in the left-right direction by energizing.

[0060] An auxiliary sliding guide (not marked in the figure) is fixedly provided on one side of the auxiliary bracket 421 facing the lifting support plate. The auxiliary sliding guide consists of a slider and a matching guide rail. The auxiliary sliding guide enables the auxiliary power unit 420 to move in a directional manner along the left and right directions.

[0061] The working principle of the auxiliary page turning component 400 is as follows: Figure 8 As shown, when the middle of the upper certificate page 11 of the certificate appears to be bulging, the auxiliary power unit drives the push rod support 426 and the first paper push rod 410 to move to the middle bulging position, and the electromagnetic coil in the push rod support 426 is energized, thereby driving the first paper push rod 410 to be pushed out in the left and right directions to the middle position of the bulging. During the page turning process of the automatic page turning component, that is, when the page turning motor 373 drives the upper paper guide roller 372 and the lower paper guide roller 374 to retreat together, the upper paper guide roller 372 and the lower paper guide roller 374 also drive the upper certificate page and the lower certificate page to retreat together. When the upper certificate page is retreated to the end and separated from the upper paper guide roller 372 (as shown in FIG. Figure 8 -b, 8-c), the first paper push rod is driven by the auxiliary power unit to move backward, so that the upper certificate pages can be turned backward smoothly. If only the reversal of the upper paper guide roller 372 and the lower paper guide roller 374 is used to turn the pages, it is possible that after the upper certificate pages are bulging in the middle, the front end of the upper certificate pages is not easy to be separated from the joint seam between the upper paper guide roller 372 and the lower paper guide roller 374. Therefore, the auxiliary page turning component 400 is used to make the upper certificate pages spread out smoothly. In the prior art, the auxiliary page turning component 400 is not used. After the upper certificate pages are bulging in the middle, the front end of the upper certificate pages is not easy to be separated from the joint seam between the upper paper guide roller 372 and the lower paper guide roller 374. This causes the problem of unsmooth page turning. In this embodiment, the auxiliary page turning component 400 is added, which can make the upper certificate pages spread out smoothly and avoid the problem of unsmooth page turning.

[0062] like Figure 1 As shown, the printing mechanism 500 includes a printing base 510 and a printer 520 located on the printing base 510 .

[0063] A first paper feeding board 530 is fixedly arranged between the printing mechanism 500 and the automatic page turning mechanism 300 , and the first paper feeding board 530 guides the certificate transmitted by the automatic page turning component 370 to the paper input end of the printing mechanism 500 .

[0064] like Fig. 9 As shown, the present embodiment also includes a stamping mechanism 600, and the stamping mechanism 600 includes a stamping base 610, on which an automatic stamping component 620 for stamping certificates is fixedly arranged, a stacking opening 611 is opened on the upper surface of the stamping base 610, and a stacking component 650 for stacking stamped certificates is fixedly arranged above the stacking opening 611, and a certificate output component 680 for delivering certificates is fixedly arranged on the stamping base 610 at the certificate output end of the stamping device.

[0065] like Fig.10As shown, the stacking assembly 650 includes a left-moving plate 651 and a right-moving plate 652 located above the stacking opening 611, a left power unit 653 fixedly arranged on the stamping base 610 for making the left-moving plate 651 approach or move away from the right-moving plate 652 along the left-right direction, and a right power unit 654 fixedly arranged on the stamping base 610 for making the right-moving plate 652 approach or move away from the left-moving plate 651 along the left-right direction.

[0066] When the certificates need to be taken out and issued uniformly after being stamped in batches, when the left-moving plate 651 and the right-moving plate 652 are in a close state, the certificates are placed on the left-moving plate 651 and the right-moving plate 652 and the automatic stamping component 620 completes the automatic stamping. After stamping, the left power unit 653 and the right power unit 654 start and move forward, the left power unit 653 drives the left-moving plate 651 to move to the left, the right power unit 654 drives the right-moving plate 652 to move to the right, the left-moving plate 651 and the right-moving plate 652 move away from each other, and the middle is open. After the certificate falls from the stacking port 611, the left power unit 653 and the right power unit 654 start and move in the opposite direction, the left power unit 653 drives the left-moving plate 651 to move to the right, the right power unit 654 drives the right-moving plate 652 to move to the left, the left-moving plate 651 and the right-moving plate 652 move close to each other, and the middle is closed, and the next certificate is transferred and placed on the left-moving plate 651 and the right-moving plate 652 for stamping.

[0067] like Fig. 9 As shown, a paper pressing portion 670 for pressing down the certificate is fixedly arranged above the left shift plate 651 and / or the right shift plate 652. The paper pressing portion 670 in this embodiment is arranged above the abutment position of the left shift plate 651 and the right shift plate 652. The paper pressing portion 670 pushes down the certificate to facilitate the stacking of the certificates.

[0068] like Fig. 9 , Fig.11 The certificate issuing assembly 680 includes a certificate issuing bracket 681 , a rotating roller 682 rotatably disposed on the certificate issuing bracket 681 , a certificate issuing power component 683 fixedly disposed on the certificate issuing bracket 681 and used to drive the rotating roller 682 to rotate, and a roller 684 abutting against the rotating roller 682 .

[0069] The above-mentioned paper pressing part 670 can be fixedly arranged on the certificate issuing bracket 681. During the certificate issuing process, the paper pressing part 670 can also press down the certificate, and flatten the certificate with the upturned edge. The flattened certificate edge is more conducive to the certificate being transmitted.

[0070] The stamping device also includes a photographing component 700, and the photographing component 700 is used to take a photo of the stamped certificate to realize electronic backup.

[0071] A protective shell (not shown in the figure) is fixed on the stamp base 610, and the protective shell covers the front, back, left, right and upper sides. The rear and front shells of the protective shell are provided with openings for the entry and exit of certificates. The left and right shells of the protective shell are provided with openings for the entry and exit of the left shift plate 651 and the right shift plate 652 respectively. The front shell of the protective shell is set as a protective door, and a safety lock is set on the protective door, which is opened by the key of the manager to prevent the seal from being lost. It plays a role of safety protection.

[0072] like Figure 1 As shown, a second paper feeding paperboard 760 is arranged between the printing mechanism 500 and the stamping mechanism 600. The second paper feeding paperboard 760 is fixedly connected to the paper outlet of the printing mechanism 500. The second paper feeding paperboard 760 is arranged to be tilted downward. The printed certificate slides on the second paper feeding paperboard 760 into the stamping mechanism 600 for stamping.

[0073] The present invention proposes an automatic page turning printing and stamping device, in which a certificate is sent from an automatic page turning mechanism to a printing mechanism for printing, and after the first page of the certificate is printed, the certificate is sent from the printing mechanism to the automatic page turning mechanism for page turning, and after the certificate is turned to the second page, the certificate is sent to the printing mechanism to print the second page of the certificate, and finally the printing mechanism enters the stamping mechanism for stamping, and the certificate is issued after stamping is completed.
