[0033] The present utility model provides a page turning device.

[0034] Please refer to Figures 1 to 3 In an embodiment of the present utility model, the page turning device comprises:

[0035] The base 100 is provided with a page turning station 101, and the page turning station 101 is used to place the certificate 500;

[0036] The page suction assembly 200 is arranged on the page turning station 101, and the page suction assembly 200 is provided with a movable suction head 230, which is used to suck up the paper of the certificate 500.

[0037] The page pushing assembly 300 is arranged on the page turning station 101, and the page pushing assembly 300 is provided with a slidable pushing block 330, which slides in the unfolding direction of the certificate 500, so as to push the paper to turn over after the suction head 230 sucks up the paper.

[0038] The technical scheme of the utility model discloses a page suction assembly 200 is arranged on the page turning station 101, and the suction head 230 of the page suction assembly 200 sucks up the paper of the certificate 500 on the page turning station 101, and then the pushing block 330 of the page pushing assembly 300 is used to push the paper to turn over, wherein before the suction head 230 sucks up the paper, the pushing block 330 slides to the outside of the paper turning opening side, after the suction head 230 sucks up the paper to a certain degree of inclination, the pushing block 330 slides along the unfolding direction of the certificate 500, and then the pushing block 330 is reset to the position before the suction head 230 sucks up the next paper.

[0039] It should be noted that the unfolding direction of the certificate 500 is the distribution direction of the position before the paper turns over and the position after the paper turns over, which presents an extension direction perpendicular to the rotation shaft of the paper turning. In this regard, after the suction head 230 sucks up the paper to a certain inclination angle, the pushing block 330 can push the paper to turn over at a relatively fast speed without controlling the suction force of the suction head 230, which improves the efficiency and accuracy of the paper turning and avoids the paper from returning to the original position after being separated from the suction head 230, thereby ensuring that the paper can be stably turned over. As for the moving direction of the suction head 230, it can be parallel to the turning direction of the paper, presenting a moving or rotating mode, or it can be perpendicular to the unfolding direction of the certificate 500, presenting a moving mode. In this regard, after the pushing block 330 abuts against the paper, the suction head 230 continues to move out of the turning range of the paper, and the pushing block 330 pushes the paper to turn over, so as to avoid the suction head 230 from interfering with the paper turning and causing the paper to deform or turn over.

[0040] In an embodiment, referring to Figures 3 to 5 The page suction assembly 200 further comprises a first sliding rail 210 and a first driving member 220 arranged at the page turning station 101, the suction head 230 is slidingly connected to the first sliding rail 210, and the first driving member 220 is drivingly connected to the suction head 230. The extension direction of the first sliding rail 210 is arranged at an acute angle with the unfolding plane of the certificate 500. It is to be noted that the first sliding rail 210 is arranged at an inclination close to the certificate 500, and on the basis of the acute angle arrangement between the extension direction of the first sliding rail 210 and the unfolding plane of the certificate 500, the suction head 230 will approach the turning direction of the paper at an oblique angle during the sliding process, which helps to reduce the sliding of the paper relative to the suction head 230 during the turning process, ensures that the paper is firmly adsorbed during the page turning process, avoids falling off or displacement, thereby increasing the stability of the suction head 230 in sucking up the paper. At the same time, the acute angle arrangement of the first sliding rail 210 enables the suction head 230 to move in a more natural and smooth manner during the page turning process, which helps to reduce the jamming or tearing phenomenon during the page turning process, and reduces the damage to the paper during the page turning process, thereby ensuring the quality of the page turning and the reliability of the subsequent certificate 500 processing. Without loss of generality, the first driving member 220, the second driving member 310, the third driving member 420, the fourth driving member 440 and the fifth driving member 130, etc. in the present scheme can be a motor, a pneumatic cylinder or an oil cylinder, etc. power member. Of course, in other embodiments, the first sliding rail 210 can also extend in an arc shape and be adapted to the turning direction of the paper, or the first sliding rail 210 extends in a direction perpendicular to the unfolding plane of the certificate 500.

[0041] Further, in the present embodiment, referring to Figure 3 and Figure 4The page suction assembly 200 is provided with two suction heads 230 and two first sliding rails 210, the two suction heads 230 are arranged on the same connecting plate 240, the connecting plate 240 is slidingly connected with the two first sliding rails 210 arranged side by side, and the output portion of the first driving member 220 is connected with the connecting plate 240 through a transmission block. By means of one connecting plate 240, the two suction heads 230 are driven to move, so that the page suction assembly 200 can process a larger range of paper sizes at the same time, and the same paper is sucked up by the two suction heads 230, which improves the stability of the paper during the turning process and ensures that the pushing block 330 can stably push the paper to turn. In this way, whether it is a smaller paper, a larger paper, a harder paper or a softer paper, it can be turned by a certain angle under the suction of the page suction assembly 200, avoiding creases or tears caused by uneven stress, and ensuring the quality of paper turning. In addition, by means of one first driving member 220, the two suction heads 230 are controlled to move synchronously through the cooperation of the double first sliding rails 210 and the connecting plate 240, which simplifies the transmission structure and ensures the synchronous movement of the two suction heads 230, so that the paper can be kept relatively uniform during the turning process. Of course, in other embodiments, the first driving member 220 can also drive a single suction head 230 to suck up the paper of the certificate 500.

[0042] For the suction of the paper by the suction head 230, in an embodiment, please refer to Figure 1 and Figure 3 The suction head 230 comprises a body portion 231 and a buffer cover 232 connected with each other, the body portion 231 is connected with the first sliding rail 210, and the buffer cover can elastically deform in the extension direction of the first sliding rail 210. It should be noted that the buffer cover 232 is used to suck and abut against the paper, and in the process of sucking up the paper by the suction head 230, the buffer cover 232 not only increases the suction surface of the suction head 230 for sucking the paper, avoiding damage to the paper due to excessive suction force at a single point, but also absorbs the impact and vibration in the movement process of the suction head 230 by means of the elastic deformation of the buffer cover 232, preventing the suction head 230 from falling off or being damaged due to direct impact, and at the same time, reducing the degree of hard collision of the suction head 230 to the paper, ensuring that the suction force of the suction head 230 can accurately act on the paper. In addition, the buffer cover 232 provides a surplus space for the movement of the suction head 230, reduces the precision of the suction head 230 sliding on the first sliding rail 210, and ensures the reliability of the suction head 230 in sucking and turning the paper. Of course, in other embodiments, the suction head 230 can also be configured as a suction disc to increase the suction surface between the suction head 230 and the paper.

[0043] In an embodiment, please refer to Figure 1 and Figure 2The pushing assembly 300 further comprises a second driving member 310 and a transmission belt 320, and the pushing block 330 is arranged on the transmission belt 320, and the second driving member 310 is drivingly connected to the transmission belt 320, so as to drive the pushing block 330 to reciprocate between the initial position for pushing the paper and the ending position after the paper is turned over. It can be understood that, by driving the transmission belt 320 through the second driving member 310, the movement of the pushing block 330 between the initial position and the ending position can be accurately controlled, so as to avoid the paper from being offset or torn due to the inaccurate position of the pushing block 330. It should be noted that the initial position for pushing the paper is that the pushing block 330 is located outside the opening of the paper when the suction head 230 does not adsorb the paper, and the ending position after the paper is turned over is that the pushing block 330 is located at the position after pushing the paper to be turned over to a predetermined degree. For the sliding of the pushing block 330 on the transmission belt 320, the second driving member 310 can control the transmission belt 320 to run stably, so that the pushing block 330 can maintain a stable speed and acceleration during the movement, and the impact on the paper caused by sudden acceleration or deceleration is avoided, thereby reducing the vibration and shaking of the paper during the turning over process, and improving the stability of the turning over. Without loss of generality, the pushing block 330 has a sliding part on the transmission belt 320 and a pushing part abutting against the paper, and for this, whether it is thin paper or thick paper, the stable turning over effect can be ensured by adjusting the tension of the transmission belt 320 and the shape of the pushing block 330. Of course, in other embodiments, the second driving member 310 can also drive the pushing block 330 to reciprocate between the initial position and the ending position through a lead screw.

[0044] In an embodiment, referring to Figure 4 and Figure 5The page turning device further comprises a page pressing assembly 400, which is arranged at the page turning station 101 and adjacent to the page sucking assembly 200. The page pressing assembly 400 is provided with a swing member 410, which is capable of swinging relative to the page turning station 101 to press the certificate 500 after the paper sheet is sucked up by the suction head 230. It can be understood that after the paper sheet is sucked up by the suction head 230, the swing member 410 of the page pressing assembly 400 can swing to a proper position to press the paper sheets that are not sucked up, thereby preventing these paper sheets from turning over with the paper sheet that is sucked up, so as to avoid turning over of multiple paper sheets at the same time, to ensure that only one paper sheet is turned over each time, and to help maintain the accuracy and stability of the page turning process and avoid page turning errors caused by turning over at the same time. At the same time, since the swing member 410 presses the paper sheets that are not sucked up, the suction force of the paper sheet by the suction head 230 and the activity efficiency of the suction head 230 can be improved without interfering with the paper sheets that are not sucked up, and correspondingly, the sliding speed of the pushing block 330 can also be improved, thereby improving the efficiency of the page turning device in turning over the certificate 500. In addition, the swing member 410 presses the paper sheets that are not sucked up to stabilize the certificate 500 at the page turning station 101. As for the force acting on the certificate 500, such as the action of the suction head 230 sucking up the paper sheet and the pushing block 330 pushing the paper sheet to turn over, the swing member 410 can provide a stable force to the certificate 500, reduce the shaking and displacement of the paper sheet during the turning over process, and ensure that the paper sheet moves according to the predetermined path and angle during the turning over process, thereby achieving more accurate and reliable page turning effect.

[0045] Further, in the present embodiment, please refer to Figure 4 and Figure 5The pressing assembly 400 further comprises a third driving member 420 and an eccentric wheel 430, the swinging member 410 comprises an angle-arranged pressing arm 411 and a transmission arm 412, the output of the third driving member 420 is transmissionally connected to the eccentric wheel 430, and the swinging member 410 is rotationally connected to the page turning station 101 at the angle-connection position of the pressing arm 411 and the transmission arm 412. The eccentric wheel 430 and the swinging member 410 rotate in parallel, and the eccentric wheel 430 can abut against the transmission arm 412. Without loss of generality, the eccentric wheel 430 is located at the side of the swinging member 410 away from the page turning station 101. When the eccentric wheel 430 abuts against the transmission arm 412, the pressing arm 411 is separated from the paper. When the eccentric wheel 430 is separated from the transmission arm 412, the pressing arm 411 presses the paper by gravity. In this way, the third driving member 420 can accurately control the abutting force of the eccentric wheel 430 on the transmission arm 412 by transmissionally connecting the eccentric wheel 430, so as to ensure that the pressing force of the swinging member 410 on the paper is moderate during the swinging process, and the paper is neither damaged due to excessive force nor fails to be effectively prevented from turning due to insufficient force. The eccentric wheel 430 and the swinging member 410 rotate in parallel, so that the eccentric wheel 430 can intermittently and stably act on the transmission arm 412, and the pressing arm 411 can maintain a stable motion track during the swinging process, thereby reducing the shaking and vibration during the swinging process, and improving the stability and accuracy of the page pressing. In addition, the third driving member 420 can continuously rotate the eccentric wheel 430 in one direction, and the eccentric wheel 430 can regularly abut against the transmission arm 412, so as to ensure the continuity of the operation of the third driving member 420, and further enable the swinging member 410 to quickly and stably repeat the paper pressing action, thereby improving the frequency of the alternating pressing of the pressing arm 411 on the paper, and improving the page turning efficiency. Of course, in other embodiments, the third driving member 420 can also realize the reciprocating driving of the swinging member 410 through a transmission structure such as a crankshaft or a cam.

[0046] In addition, for the type of the turned paper, in an embodiment, please refer to Figure 4 and Figure 5The page turning device further comprises a rolling brush 450 and a fourth driving member 440. The rolling brush 450 is arranged adjacent to the page turning station 101. The rotating direction of the rolling brush 450 and the turning direction of the paper of the certificate 500 are arranged at an angle. The fourth driving member 440 is drivingly connected to the rolling brush 450. During the process of the suction head 230 sucking the paper, the bristles of the rolling brush 450 and the paper of the certificate 500 rollingly abut. It can be understood that the rollingly abutting action of the rolling brush 450 can assist the separation of the papers. Especially when the papers are soft and easy to stick, the rotation of the rolling brush 450 can reduce the friction between the papers, so that the paper sucked by the suction head 230 is more easily separated from the next paper, thereby avoiding the problem that multiple papers are turned at the same time. At the same time, the rotating direction of the rolling brush 450 and the turning direction of the paper are arranged at an angle. The bristles are distributed along the outer periphery of the rolling brush 450. During the rotation of the rolling brush 450, the force direction of the bristles acting on the certificate 500 is at the joint between adjacent papers, thereby promoting the separation of the papers, reducing the interference with the paper sucked by the suction head 230, and improving the accuracy and stability of the page turning. In this way, by reducing the sticking and jamming between the papers, the page turning device can shorten the time required for page turning, and improve the processing efficiency of the certificate 500. Of course, in other embodiments, air flow can also be applied parallel to the direction of the page turning station 101 to promote the separation of adjacent papers and reduce the interference with the paper sucked by the suction head 230.

[0047] In an embodiment, referring to Figure 1 and Figure 4The page turning device further comprises a pressing member 120, a fifth driving member 130, and a conveying belt 110 arranged in the page turning station 101, the conveying belt 110 is used to convey the certificate 500, the fifth driving member 130 is drivingly connected to the pressing member 120, the pressing member 120 is arranged adjacent to the page turning station 101 and can move vertically, and the pressing member 120 is used to push the certificate 500 to be placed on the conveying belt 110. It can be understood that the conveying belt 110 is used to convey the certificate 500 to the page turning station 101 and convey the page turned certificate 500 to the next station, so that the continuous processing of the certificate 500 is realized and the processing efficiency is ensured. After the pushing block 330 pushes the paper to the turning position, the fifth driving member 130 drives the pressing member 120 to push the certificate 500 downward to be attached to the conveying belt 110, so that the conveying belt 110 can convey the certificate 500 to the next station, and the page turning device can be automatically connected with the upstream and downstream processing devices of the conveying belt 110. Without loss of generality, the pressing member 120 is configured as a pressing plate and a sliding rod, the sliding rod is slidingly connected to the base 100, the fifth driving member 130 drives the pressing plate to move up and down, and the pressing plate moves vertically and reciprocally under the guidance of the sliding rod, so that the pressing member 120 pushes the certificate 500 to the appropriate position of the conveying belt 110 before the conveying belt 110 conveys the certificate 500 to the next processing position, and the continuity and efficiency of the processing operation are ensured. Of course, in other embodiments, a pressing block can be arranged on the pushing block 330, and after the pushing block 330 pushes the paper to the turning position, the pressing block moves downward to push the certificate 500 to the appropriate position of the conveying belt 110, so that the continuity of the processing operation of the certificate 500 is ensured.

[0048] The utility model further provides a certificate processing equipment, this certificate processing equipment includes page turning device, the specific structure of page turning device refers to the above -mentioned embodiment, because this certificate processing equipment adopts all technical schemes of above -mentioned embodiment, therefore at least has all beneficial effects brought by technical scheme of above -mentioned embodiment, here will not repeat again.
