[0027] In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0028] Please refer to Figures 1 to 4 , now the single-motor multi-stage transmission page turning mechanism provided by the embodiment of the present application will be described. The single-motor multi-stage transmission page turning mechanism comprises:

[0029] a fixed plate 10;

[0030] an electric assembly 20 disposed on the fixed plate 10;

[0031] a multi-stage transmission assembly 30 disposed on both sides of the fixed plate 10, comprising a first page turning gear 31, a first page turning hook 32 and a crank wheel 33, the first page turning gear 31 is connected with the electric assembly 20, the first page turning hook 32 is disposed on the inner side of the first page turning gear 31, and the crank wheel 33 is coaxially disposed with the first page turning gear 31;

[0032] The turnover frame 40 is movably arranged on the fixed plate 10 and is provided with a page suction assembly 41.

[0033] The motor assembly 20 is configured to drive the first page turning gear 31 to rotate, and the crank wheel 33 is configured to periodically swing the turnover frame 40 when the first page turning gear 31 rotates.

[0034] It can be understood that, after the certificate is placed on the fixed plate 10, the turnover frame 40 swings downward under the action of gravity in a natural state, and the page suction assembly 41 can be adsorbed with the pages of the certificate. When the motor assembly 20 is started, the motor assembly 20 drives the first page turning gear 31 to rotate, and the crank wheel 33 periodically swings the turnover frame 40 when the first page turning gear 31 rotates. When the turnover frame 40 swings upward, the page suction assembly 41 swings upward, thereby separating the adsorbed certificate pages. At the same time, the first page turning hook 32 rotates with the first page turning gear 31, and the first page turning hook 32 enters the gap between the separated certificate pages when rotating. The first page turning hook 32 continues to rotate to complete the page turning action of the certificate.

[0035] It is worth mentioning that, in order to improve stability, all gears in the multi-stage transmission assembly 30 in the present application can be arranged in pairs.

[0036] Compared with the prior art, the single-motor multi-stage transmission page turning mechanism provided by the present application can realize page separation and page turning of the certificate based on the same power source, improves action coordination, simplifies the transmission structure, and reduces production cost.

[0037] In another embodiment of the present application, please refer to Figure 1 The fixed plate 10 includes a bottom plate 11 and side plates 12 arranged vertically on both sides of the bottom plate 11, and the bottom plate 11 is provided with a certificate placement position 111.

[0038] It can be understood that the certificate placement position 111 is beneficial to keep the position of the certificate unchanged and improve page turning quality.

[0039] In another embodiment of the present application, please refer to Figure 5 The motor assembly 20 includes a servo motor 21, an output gear 22, and a first intermediate gear 23. The output gear 22 is arranged on the output shaft of the servo motor 21, and the output gear 22 is in transmission with the first page turning gear 31 through the first intermediate gear 23.

[0040] It can be understood that the first intermediate gear 23 can adjust the transmission ratio and change the rotation direction.

[0041] Further, please refer to Figure 2And Figure 5 The multi-stage transmission assembly 30 further comprises an anti-sticking gear 34, which is arranged between the first intermediate gear 23 and the first page turning gear 31, and a brush 341 is arranged on the rotation shaft of the anti-sticking gear 34.

[0042] It can be understood that the brush 341 can rotate with the anti-sticking gear 34, and the brush 341 can separate the adhered pages, so as to avoid turning multiple pages at one time.

[0043] In another embodiment of the present application, please refer to Figure 4 The page suction assembly 41 comprises a vacuum pump 411, an electromagnetic valve 412 and a suction disc 413, the vacuum pump 411 is connected with the suction disc 413 through an air pipe, and the electromagnetic valve 412 is connected with the suction disc 413 through a spring 414.

[0044] It can be understood that the vacuum pump 411 is used to provide negative pressure, and the electromagnetic valve 412 is used to move the suction disc 413, when the turning frame 40 swings down under the action of gravity, the page suction assembly 41 is in contact with the pages of the certificate, and the pages of the certificate are adsorbed, at the same time, in the turning process, the suction disc 413 compresses the spring 414 under the pulling force of the electromagnetic valve 412, so as to bend the pages of the certificate upwards, and increase the gap of the separated pages; when the first page turning hook 32 enters the gap between the separated pages of the certificate during rotation, the electromagnetic valve 412 and the vacuum pump 411 are closed.

[0045] In another embodiment of the present application, please refer to Figure 2 And Figure 5 The multi-stage transmission assembly 30 further comprises a second page turning gear 35 and a second intermediate gear 36, the second page turning gear 35 is connected with the first page turning gear 31 through the second intermediate gear 36, and a second page turning hook 351 is arranged on the second page turning gear 35.

[0046] It can be understood that, since the second page turning gear 35 is connected with the first page turning gear 31 through the second intermediate gear 36, the second page turning gear 35 can rotate in the same direction with the first page turning gear 31, so that when the pages are turned up by the first page turning hook 32 of the first page turning gear 31, the pages can be further turned by the second page turning hook 351, so as to increase the turning angle and improve the turning quality.

[0047] Further, please refer to Figure 2 And Figure 5The multi-stage transmission assembly 30 further comprises a third page turning gear 36 and a third intermediate gear 37, the third page turning gear 36 is connected with the second page turning gear 35 through the third intermediate gear 37, and a plurality of third page turning hooks 361 are arranged on the third page turning gear 36.

[0048] It can be understood that, since the third page turning gear 36 is connected with the second page turning gear 35 through the third intermediate gear 37, the third page turning gear 36 can rotate in the same direction with the second page turning gear 35 and the first page turning gear 31, so that when the page is turned up by the second page turning hooks 351 of the second page turning gear 35, the third page turning hooks 361 can continue to turn the page and press it down, so as to further increase the turning angle of the page and press the turned page down to avoid rebounding.

[0049] The above only describes the preferred embodiments of the present application and is not used to limit the present application, any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
