Specifically, in one example of the present application, as shown in fig. 3, the page turning mechanism 200 includes: a page turning platform 210, a first inverter 220, and a second inverter 230. The page turning platform 210 is used for placing an article 001 to be printed. The first turner 220 is disposed on the page turning platform 210, preferably near an end of the page turning platform 210 in the length direction; the second inverter 230 is preferably located near the middle of the paging platform 210. For example, when the length of the page turning platform 210 is 350mm, the first inverter 220 is located at a position of about 60mm from the end, and the second inverter 230 is located at a position of about 120mm from the end. The first inverter 220 is configured to have a first use state in which the first inverter 220 is configured to bend an uppermost page of the article 001 to be printed upward so as to form an arch space with other sheets located therebelow, and a first retracted state. In the first retracted state, the first inverter 220 is stationary and separated from the paper. The number of second turners 230 is greater than or equal to one and is located on the side of the page turning platform 210, and it is understood that when the number of second turners 230 is two, it is preferable that two second turners 230 are located on opposite sides of the page turning platform 210 to perform page turning better. The second turner 230 is configured to have a second use state and a second storage state, in the second use state, the second turner 230 achieves turning of the uppermost page from a state in which a first surface of the uppermost page is upward to a state in which a second surface opposite to the first surface is upward, that is, the page turning action is completed; in the second retracted state, the second inverter 230 is in a stationary state and separated from the sheet, and does not participate in the page turning operation.

Further, in one example of the present application, with continued reference to fig. 3, the first inverter 220 includes a first driver 221, a second driver 222, a rotation shaft 223, and a page turning wheel 224. The first driving member 221 and the second driving member 222 may each be a motor. The rotation shaft 223 is connected to both the first driving member 221 and the second driving member 222, and the first driving member 221 is illustratively connected to the rotation shaft 223 through a first swing arm 225, and the first swing arm 225 is illustratively an elongated member, wherein an output shaft of the first driving member 221 is connected to one end of the first swing arm 225 and the rotation shaft 223 is connected to the other end of the first swing arm 225. The rotation shaft 223 is switched between a first use state and a first stow state by the driving of the first driving member 221; the rotation shaft 223 is axially rotated around the second driving member 222. The page turning wheels 224 are fixedly arranged on the rotating shaft 223, so that the page turning wheels 224 rotate along with the rotating shaft 223, and in the first use state, the page turning wheels 224 are tangential to the preset position of the paper, for example, the number of the page turning wheels 224 is 3, and the diameters of the three page turning wheels 224 are the same, but the axial lengths can be different or the same. In a specific embodiment, the page turning wheel 224 is made of a material with high friction, such as rubber, and preferably, a plurality of protrusions are disposed on the outer surface of the page turning wheel 224, so as to increase friction and realize faster page turning.

Further, in one example of the application, with continued reference to fig. 3, the second inverter 230 includes a third drive 231, a fourth drive 232, a telescoping rod 233, and a second rocker arm 234. The telescopic rod 233 is connected to the third driving member 231, and the telescopic rod 233 is switched between an extended state and a retracted state by the driving of the third driving member 231; the third drive member 231 is connected to the fourth drive member 232 by a second rocker arm 234. Illustratively, the second swing arm 234 is an elongated member, the output shaft of the fourth drive member 232 is coupled to one end of the second swing arm 234, and the third drive member 231 and the telescoping rod 233 are disposed at the other end of the second swing arm 234. The third driving member 231 and the fourth driving member 232 may each be a motor.

When the page needs to be turned, the first turner 220 is driven by the first driving member 221 to switch from the first retracted state to the first usage state, at this time, the page turning wheel 224 contacts with the paper to be turned, and driven by the second driving member 222, the page turning wheel 224 rotates around its axial direction, and friction is generated on the paper to be turned, so that the uppermost page of the object 001 to be printed is bent upwards to form an arch space with other papers below the uppermost page. At this time, after the telescopic rod 233 is inserted into the arch space under the driving of the third driving member 232, the third driving member 231 and the telescopic rod 233 are driven to turn over together by the second rocker arm 234, so as to drive the uppermost page of the article 001 to be printed to expand the arch space upwards, thereby being completely separated from the paper below the arch space and realizing page turning.

Illustratively, the number of telescoping rods 233 is two on opposite sides of the paging platform 210, and each telescoping rod 233 is separately configured with a third drive 231 and a fourth drive 232, but it should be understood by those skilled in the art that both third drives 231 and both fourth drives 232 operate in synchronization.

Specifically, in one example of the present application, the page turning mechanism 200 further includes a shutter 240, a fifth driver (not shown), and a first sensor 250. Baffle 240 parcel is at least partial edge at page turning platform 210, and baffle 240 upwards extends, and the effect of baffle 240 is for waiting to print article 001 to carry out spacingly on the one hand, avoids it to drop from page turning platform 210, and on the other hand is waiting to print article 001 to place at page turning platform 210 in-process, and baffle 240 still can be to wait to print article 001 put the angle and lead. The fifth driving member is connected to the page turning platform 210, and the fifth driving member is used for driving the page turning platform 210 to move in a first direction, so that one end of the to-be-printed article 001 abuts against the baffle 240, thereby achieving a page turning position. The fifth driving member may be a motor, and the page turning platform 210 is in the form of a belt, and the belt is driven by the motor to drive the printed article 001 thereon to move in the first direction, that is, in the direction of the baffle 240. The first sensor 250 is disposed on the page turning mechanism 200 and is close to the shutter 240, and the first sensor 250 is configured to acquire information about whether one end of the article 001 to be printed is in contact with the shutter 240, and the position when in contact is considered to be the page turning position of the printed article 001. The first inverter 220 is configured to switch to a first use state when one end of the object 001 to be printed abuts against the shutter 240, so as to perform a subsequent page turning process.

Illustratively, the first sensor 250 is a photosensor. When one end of the article 001 to be printed abuts against the baffle 240, the article 001 to be printed can block the photoelectric sensor, and the photoelectric sensor detects the blocked signal, so that the article 001 to be printed is judged to be in the page turning position; otherwise, when the photoelectric sensor does not detect the shielded signal, the object 001 to be printed is judged not to be at the page turning position.

Therefore, the page turning mechanism 200 of the application realizes the page turning of the certificate waiting for the printed article through the cooperation of the structures of the page turning platform 210, the first turner 220, the second turner 230 and the like, and greatly improves the success rate of page turning.

Preferably, in one example of the present application, with continued reference to fig. 1 or 2, the printing apparatus further includes a storage compartment 400 disposed above the printer 100, the storage compartment 400 being configured to store the to-be-printed articles 001, and a plurality of to-be-printed articles 001 may be stacked in advance, and the driving mechanism 300 may take the to-be-printed articles 001 one by one when needed. The page turning mechanism 200 is disposed above the printer 100 and side by side with the storage compartment. The apertures of the inlet 110 and the first outlet 120 are adapted to the length of the article 001 to be printed in the unfolded state, and the arrangement directions of the page turning platform 210 and the storage cabin 400 are parallel to the length direction of the article 001 to be printed in the unfolded state, that is, the length direction of the page turning platform 210 and the length direction of the storage cabin 400 are consistent to the length direction of the article 001 to be printed in the unfolded state. So that the length of the platform on which the page turning platform 210 and the storage compartment 400 are placed can be reduced, thereby reducing the length of the printing apparatus in the horizontal direction. And the page turning mechanism 200 and the storage cabin 400 are arranged above the printer 100, so that the space above the printer 100 can be fully utilized, and the height of the printing device in the vertical direction can be reduced. Taking the article 001 to be printed as a property certificate as an example, the printing device is usually placed in a property center, and the smaller the volume is, the better the printing device is, so the layout printing device is arranged by adopting the mode, and the requirement of an actual use scene can be met as much as possible.

Further, in one example of the present application, as shown in fig. 2, 4, 5, and 6, the driving mechanism 300 is controllably moved in at least one direction, and illustratively, as shown in fig. 2, the printing apparatus further includes a rail 810 and a fixing frame 800, and the rail 810 is disposed on the fixing frame 800, such as a horizontal rail. The transmission 300 is controllably moved on the rail 800, for example by a drive motor. It will be understood, of course, that in addition to the horizontal rails shown in the present embodiment, vertical rails or the like may be further included to enable the transmission 300 to move in a predetermined range and direction. The above-described arrangement of the rail 810 suffices for the transfer of the article 001 to be printed.

The transmission mechanism 300 comprises a mechanical arm 310 and an adsorption mechanism, and the adsorption mechanism is mounted on the mechanical arm 310. The suction mechanism includes a mounting plate 370, a platen 320, a suction cup 330, and a vacuum mechanism. The mechanical arm 310 may adopt an existing mechanical arm structure, so long as the mechanical arm capable of realizing smooth movement of the object 001 to be printed in the present application can be applied to the present application, for example, the mechanical arm 310 is an existing six-degree-of-freedom mechanical arm, and the structure and the working principle thereof are not repeated herein. Illustratively, as shown in fig. 4, the mechanical arm 310 includes a first driving motor 311 for tilting the print object 001 with respect to a horizontal plane when the suction mechanism sucks the print object 001, and a second driving motor 312 for rotating the print object 001 in a plane (for example, in the horizontal plane). The mounting plate 370 is coupled to the robotic arm 310, e.g., the mounting plate 370 is coupled to the robotic arm 310 via a mount 371. The paper pressing plate 320 is movably mounted on the mounting plate 370 through a plurality of connecting rods 380, the mounting plate 370 is provided with mounting holes for the connecting rods 380 to pass through, and the upper end part of the connecting rods 380 is also provided with a limit part 381, such as a limit nut, for preventing the connecting rods 380 from falling out of the mounting holes; a spring 390 is also sleeved on the connecting rod 380, and two ends of the spring 390 respectively abut against the mounting plate 370 and the paper pressing plate 320. So that when the platen 320 is subjected to an upward force, the force compresses the spring 390 causing the platen 320, along with the connecting rod 380, to move upward, i.e., in a direction toward the mounting plate 370, relative to the mounting plate 370. The paper pressing plate 320 serves to flatten the article 001 to be printed before adsorbing the article 001 to be printed, thereby avoiding warping. The number of the suction cups 330 is at least two, and the suction cups 330 are disposed at both sides of the paper pressing plate 320 to suck the object 001 to be printed, and the number of the suction cups 330 is two, for example. The vacuum mechanism is connected with the sucker 330, so that the suction force of the article 001 to be printed is enough, and interference with other structures in the moving process caused by falling of the paper below the sucked paper is avoided. Illustratively, the suction cup 330 is also movably mounted on the mounting plate 370, the suction cup 330 is connected to the mounting plate 370 through a connection tube 331, and the suction cup 330 communicates with the vacuum mechanism through the connection tube 331, thereby providing negative pressure; preferably, a spring is also sleeved on the connecting tube 331, and the action mode is similar to that described above, so that the sucker 330 is ensured to have a certain floating distance in the vertical direction, and better contact and adsorption with the article 001 to be printed are facilitated.

Preferably, the distance between the platen 320 and the mounting plate 370 is greater than the distance between the suction cups 330 and the mounting plate 370. So configured, when the mechanical arm 310 drives the suction mechanism to approach the article 001 to be printed, the paper pressing plate 320 first contacts the article 001 to be printed and flattens the paper, and at this time, the article 001 to be printed prevents the paper pressing plate 320 from continuing to move downwards. Then, the mounting plate 370 will continue to move downwards under the driving of the mechanical arm, the spring 390 on the connecting rod 380 is compressed, and the sucking disc 330 will contact the object 001 to be printed and suck it, so that the object 001 to be printed can be transferred to the page turning platform 210 or removed from the page turning platform 210.

Preferably, the suction mechanism further includes a corner pressing piece 360, and the arrangement position of the corner pressing piece 360 on the mounting plate 370 is configured such that when the suction mechanism sucks the article 001 to be printed, the corner pressing piece 360 is opposed to the corner of the sheet of the article 001 to be printed, thereby preventing warping thereof. Preferably, referring to fig. 5, the number of the corner pressing pieces 360 is two, in a state of adsorbing the article 001 to be printed, the positions of the corner pressing pieces 360 are set to be opposite to two corners of the paper of the article 001 to be printed, the sides of the paper corresponding to the two corner connecting lines are the sides which enter the printer from the inlet first, and further through the arrangement of the two corner pressing pieces 360, the corners of the paper entering the printer are prevented from being warped to cause paper jam and other phenomena. Of course, it is understood that the number of corner presses 360 may be four, each opposite a respective one of the four corners of the sheet. The corner fitting 360 is mounted in a manner similar to that of the paper pressing plate 320. The corner pressing piece 360 is movably mounted on the mounting plate 370 through a connecting rod, a mounting hole for the connecting rod to pass through is formed in the mounting plate 370, and a limiting part is further arranged at the upper end part of the connecting rod and used for preventing the connecting rod from falling from the mounting hole; the connecting rod is also sleeved with a spring, and two ends of the spring are respectively abutted against the mounting plate 370 and the corner pressing piece 360.
