[0040] A page turning roller group, the page turning roller group comprising at least one page turning roller assembly 2 arranged corresponding to the page turning channel 12;

[0041] A conveying roller set, the conveying roller set includes at least one conveying roller assembly 3 corresponding to the certificate crimping channel 11, the conveying roller assembly 3 is suitable for being driven to rotate to convey the spread certificate and convey it in a first direction so that the certificate is in a page turning position during the conveying process, that is, at least part of the half of the spine of the spread certificate is pressed in the conveying roller assembly 3, and at least part of the other half of the spine is pressed under the page turning roller assembly 2; wherein,

[0042] The page turning roller assembly 2 is adapted to be driven to rotate when the certificate is at the page turning position so as to act on at least one page of the certificate pressed under the page turning roller assembly 2 so that the page is turned from the upper end opening of the page turning channel 12 to above the page turning roller assembly 2;

[0043] The conveying roller assembly 3 is also adapted to be driven to rotate to convey the certificate in the second direction after at least one page of the certificate pressed under the page turning roller assembly 2 is turned over to the page turning roller assembly 2, thereby realizing page turning;

[0044] The first direction is opposite to the second direction. Figure 1 In the figure, the first direction is specifically the direction to the left along the certificate channel, and the second direction is specifically the direction to the right along the certificate channel.

[0045] In this embodiment, if Figure 1 As shown, two certificate crimping channels 11 are provided, one page turning channel 12 is provided, and the two certificate crimping channels 11 are respectively located on both sides of the page turning channel 12 .

[0046] The page turning roller assembly 2 is also suitable for being driven to rotate after at least one page of the certificate pressed under the page turning roller assembly 2 is turned onto the page turning roller assembly 2, so as to transport the certificate to the second direction together with the conveying roller assembly 3.

[0047] Specifically, Figure 2 As shown, the certificate crimping channel 11 is formed by the area between the upper crimping channel plate 41 and the lower crimping channel plate 42 .

[0048] Specifically, Figure 2 As shown, a bending edge 41a suitable for providing tension for the arching of the certificate page extends obliquely upward from one side of the upper crimping channel plate 41 close to the page turning channel 12. The bending edge 41a is mainly provided to provide tension for the arching of the certificate page.

[0049] Specifically, the page turning channel 12 is formed by the area between the lower page turning channel plate 5 and the page turning roller assembly 2 .

[0050] Specifically, Figure 8As shown, an elastic structure 6 is provided on the lower page turning channel plate 5, and the interval between the lower page turning channel plate 5 and the page turning roller assembly 2 is self-adjusted by the elastic structure 6; the elastic structure 6 can be arranged between the lower page turning channel plate 5 and the installed frame, so that after the certificate enters the page turning channel 12, the lower page turning channel plate 5 can be pressed down to realize the function of self-adjusting the interval between the lower page turning channel plate 5 and the page turning roller assembly 2, and reasonably avoid the problem caused by excessive pressing force of the page turning roller; in this embodiment, the elastic structure 6 can be a spring.

[0051] Specifically, Figure 2 As shown, the conveying roller assembly 3 includes conveying rollers arranged in pairs up and down, and the conveying rollers include a conveying roller shaft 31a suitable for being driven to rotate and at least one conveying roller wheel 31b installed on the conveying roller shaft 31a. The conveying roller shaft 31a can be connected to a driving source through a transmission mechanism, and the forward and reverse rotation of the conveying roller shaft 31a can be controlled by controlling the driving source to achieve the needs of conveying in the first direction and conveying in the second direction; the driving source can be a motor.

[0052] In this embodiment, a plurality of conveying rollers 31 b may be provided along the axial direction of the conveying roller shaft 31 a.

[0053] Specifically, the page turning roller assembly 2 has at least one page turning roller wheel 21; the page turning roller assembly 2 also includes a page turning roller shaft 22, and the page turning roller wheel 21 is installed on the page turning roller shaft 22; wherein,

[0054] The page turning roller 21 includes but is not limited to the following structures:

[0055] like Figure 4 A first structure of the page turning roller 21 is shown: the outer circumference of the page turning roller 21 is at least partially toothed;

[0056] like Figure 5 The second structure of the page turning roller 21 is shown: the outer circumference of the page turning roller 21 is partially flexible and partially rigid, which can ensure that a soft contact method is used to provide appropriate force during the page turning process.

[0057] like Figure 6 A third structure of the page turning roller 21 is shown: the page turning roller 21 is provided with at least two radially protruding flexible sheet bodies 21a in the circumferential direction.

[0058] like Figure 7 A fourth structure of the page turning roller 21 is shown: the page turning roller 21 may be a roller made of a foam material, and the flexible characteristics of the foam material are utilized to apply a suitable page turning force to the certificate page.

[0059] In this embodiment, a plurality of page turning rollers 21 may be provided along the axial direction of the page turning roller shaft 22 .

[0060] Specifically, Figure 3 As shown, the page turning channel 12 is formed by the area between the lower page turning channel plate 5 and the page turning roller assembly 2 ; wherein, the lower page turning channel plate 5 is provided with an avoidance groove 51 corresponding to the page turning roller 21 .

[0061] The specific working mode of this certificate page turning device is as follows:

[0062] The certificate is transported to the page turning position in an open manner (spread out) (taking the right page as an example), at which time the transport roller assembly and the page turning roller assembly on the left side hold the certificate at the page turning position with a certain pressing force.

[0063] The transport roller assembly remains stationary, and the page turning roller of the page turning roller assembly rotates clockwise. Due to the difference in stiffness between the certificate page and the certificate cover, when the page is rubbed with the specified crimping force, the certificate page can be rubbed up and the cover can be kept stationary; at this time, the force condition is as follows Fig. 9 As shown, Fig. 9 In the figure, A is the page that needs to be turned, B is the cover of the certificate, and the pressure of the page turning roller on the certificate is F;

[0064] The friction coefficient between the page turning roller and the certificate is μ1, and the friction force between the page turning roller and the certificate is f1=μ1F;

[0065] The friction coefficient between the certificate page and the certificate cover is μ12 (μ12<μ1), and the friction force between the certificate page and the certificate cover is f12=μ12F.

[0066] The resistance generated by the stiffness of the certificate page is D1;

[0067] The resistance generated by the stiffness of the certificate cover is D2;

[0068] When D1<f1-f12<D2, the certificate page can be turned up without turning up the certificate cover (the certificate needs to be pressed down by the conveying roller assembly on the left to ensure that the overall position does not move)

[0069] The page turning roller continues to rotate clockwise, and the bent edge 41a on the upper crimping channel plate 41 can provide tension for the arching of the certificate page, ensuring a certain crimping force between the edge of the page and the page turning roller. When the page turning roller continues to rotate, the edge of the page can be smoothly turned up to the top of the page turning roller;

[0070] At this time, the page turning roller and the transport roller rotate counterclockwise in opposite directions to transport the certificate to the right, and the page above the page turning roller can be completely turned over. The certificate continues to be transported to the right until the page after the page is turned is pressed by the page turning roller, and the page turning is completed.

[0071] When the page is arched and turned over the page turning roller, the tip of the arched paper is tangential to the roller, which may cause the page and the roller to slip and make it impossible to turn the page completely.

[0072] If you choose a toothed page-turning roller, you can use the teeth of the page-turning roller to lift the front end of the page until the page is completely turned over.

[0073] The certificate page turning device of this embodiment can turn over only one page, and can turn over multiple pages at the same time.

[0074] To turn the pages in the reverse direction, simply move the certificate to the right and press the page-turning roller on the other side of the certificate.

[0075] The page turning roller assembly of this embodiment applies appropriate page turning force. To ensure the stability of the overall page turning, multiple pairs of page turning roller assemblies can be configured simultaneously for certificates with larger page widths. To ensure the optimization of the page turning force, the page turning roller wheels in this embodiment are preferably roller wheels with circumferential teeth, and an avoidance groove is provided on the lower page turning channel plate. The flexibility of the top of the teeth and the rigidity of the certificate are reasonably utilized to achieve the page turning force being satisfied without causing excessive resistance to result in insufficient page turning force or damage to the certificate.
