[0032] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0033] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0034] The flipping mechanism 100 of the double-sided printing device for a certificate according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] like Figure 1 and Figure 2 As shown, the flipping mechanism 100 of the document double-sided printing device according to an embodiment of the present invention includes a base 10 , a transmission assembly 20 , a driving assembly 30 and a flipping member 40 .

[0036] Specifically, the base 10 is configured to receive the outlet 212 of the device body 200. A transmission assembly 20 is disposed on the base 10 and is configured to transport the print medium 60. A drive assembly 30 is disposed on one side of the base 10 and is connected to the transmission assembly 20 to drive the movement of the transmission assembly 20. A flip member 40 is connected to the transmission assembly 20 and is reversible relative to the base 10. The end of the flip member 40, facing away from the base 10, receives the connecting plate 211 of the transport mechanism 210. The transmission assembly 20 drives the print medium 60 along the extension direction of the flip member 40 to feed the print medium 60 into the transport mechanism 210 of the printing device.

[0037] In other words, the flipping mechanism 100 of the double-sided ID card printing device according to the embodiment of the present invention is primarily used to transport and flip the print medium 60. By providing the flipping mechanism 100, the print medium 60, after printing on the front or back side, can be guided by the flipping mechanism 100 to the transport mechanism 210 in the printing device for printing on the other side (back or front) of the print medium 60. This eliminates the need for manual flipping of the print medium 60, thereby improving printing efficiency and saving labor and time costs.

[0038] like Figure 1 and Figure 2 As shown, the flip mechanism 100 is mainly composed of a base 10, a transmission assembly 20, a drive assembly 30 and a flip member 40. Figure 3The base 10 is configured to receive the outlet 212 of the device body 200. After printing on the front side of the print medium 60 in the transport mechanism 210, the print medium 60 is introduced into the flipping mechanism 100 through the outlet 212 of the device body 200. The flipping mechanism 100 then feeds the reverse side of the print medium 60 into the transport mechanism 210 for reverse printing. A transmission assembly 20 is mounted on the base 10 and is used to transport the print medium 60. A drive assembly 30 is mounted on one side of the base 10 and is connected to the transmission assembly 20. The drive assembly 30 is capable of driving the transmission assembly 20. The print medium 60 is then transferred to the flipping member 40 via the transmission assembly 20. The flip member 40 is connected to the transmission assembly 20. The flip member 40 can be flipped relative to the base 10. The end of the flip member 40 away from the base 10 is used to receive the connecting plate 211 of the transmission mechanism 210. The transmission assembly 20 drives the printing medium 60 to move along the extension direction of the flip member 40. Under the action of the flip member 40, the printing medium 60 is lifted to the connecting plate 211 of the transmission mechanism 210 (see Figure 3 ), thereby sending the printing medium 60 into the transmission mechanism 210 of the printing device for printing on the other side, thereby realizing double-sided printing of the printing medium 60.

[0039] Therefore, according to the flipping mechanism 100 of the double-sided printing device for ID cards according to an embodiment of the present invention, a flipping member 40 is provided on the base 10, and the printing medium 60 is fed into the transmission mechanism 210 of the printing device through the flipping member 40. Double-sided printing of the printing medium 60 can be achieved without manual operation, thereby improving printing efficiency and reducing time and labor costs.

[0040] According to one embodiment of the present invention, the base 10 includes: a first base 11 and a second base 12, the second base 12 is arranged on the first base 11, and an accommodating cavity is defined between the first base 11 and the second base 12, the transmission assembly 20 is arranged in the accommodating cavity, and a portion of the transmission assembly 20 extends out of the second base 12, one end of the flip member 40 is arranged in the accommodating cavity, and the other end of the flip member 40 extends obliquely away from the second base 12.

[0041] That is, see Figure 1 and Figure 2The base 10 is primarily composed of a first base 11 and a second base 12. The second base 12 is disposed on the first base 11, defining a receiving cavity between the first base 11 and the second base 12. The transmission assembly 20 is mounted within the receiving cavity, and a portion of the transmission assembly 20 extends out of the second base 12. The portion extending out of the second base 12 can be used to transport the print medium 60. One end of the flip member 40 is mounted within the receiving cavity, and the other end of the flip member 40 extends obliquely away from the second base 12 into the transport mechanism 210 of the printing device, facilitating the re-entry of the print medium 60 into the transport mechanism 210 for printing on the other side. This enables the printing device to print on both sides of the print medium 60, improving printing efficiency and saving manpower and time costs.

[0042] In some embodiments of the present invention, the first base 11 is a square plate, and the driving assembly 30 is disposed on the first base 11. The second base 12 is a square frame, and a guide groove 13 is provided on the second base 12, and a portion of the transmission assembly 20 is located in the guide groove 13.

[0043] In other words, if Figure 2 As shown, the first base 11 can be designed roughly as a square plate, and the drive assembly 30 is mounted on the first base 11. The second base 12 can be configured roughly as a square frame. A guide groove 13 is provided on the second base 12. A portion of the transmission assembly 20 is located in the guide groove 13. The portion of the transmission assembly 20 located in the guide groove 13 rolls to form a guide surface, which facilitates the transfer of the print medium 60 to the flip member 40. The portion of the transmission assembly 20, in conjunction with the flip member 40, lifts the print medium 60 and feeds it into the conveying mechanism 210 for reverse printing.

[0044] According to one embodiment of the present invention, the transmission assembly 20 includes a plurality of pulleys 21 , a plurality of rotating shafts 22 and a belt 23 .

[0045] Specifically, at least one pulley 21 is connected to the driving assembly 30. A plurality of rotating shafts 22 are arranged at intervals in the transmission direction, and each rotating shaft 22 is respectively connected to a corresponding pulley 21. A belt 23 is sleeved on two adjacent rotating shafts 22.

[0046] That is, see Figure 2The transmission assembly 20 is mainly composed of multiple pulleys 21, multiple rotating shafts 22 and belts 23. Among them, at least one pulley 21 is connected to the driving assembly 30, and the driving assembly 30 drives the pulley 21 to rotate. Multiple rotating shafts 22 are arranged at intervals in the transmission direction, and each rotating shaft 22 is respectively equipped with a bearing 24. Each rotating shaft 22 is respectively connected to the corresponding pulley 21. The belt 23 is sleeved on two adjacent rotating shafts 22. The pulley 21 is driven to rotate by the driving assembly 30, which in turn drives the rotating shaft 22 to rotate, thereby realizing the rotation of the belt 23. Under the action of the belt 23, the printing medium 60 moves relative to the base 10, thereby being transmitted to the flip member 40 and finally introduced into the transmission mechanism 210.

[0047] According to one embodiment of the present invention, the driving assembly 30 includes two driving motors 31 and a coupling 32 .

[0048] Specifically, two drive motors 31 are spaced apart and arranged on one side of the base 10 , and the drive motors 31 are connected to the pulley 21 . A coupling 32 is provided on the base 10 , and the coupling 32 is connected to one of the drive motors 31 .

[0049] That is to say, if Figure 1 and Figure 2 As shown, the drive assembly 30 primarily consists of two drive motors 31 and a coupling 32. The two drive motors 31 are spaced apart and mounted on one side of the base 10. The drive motors 31 are connected to the pulleys 21, driving the pulleys 21 for rotation. A coupling 32 is mounted on the base 10 and connected to one of the drive motors 31. The coupling 32 allows the drive motors 31 to be coaxially arranged with the rotating shaft 22, facilitating the drive motors 31 to drive the pulleys 21 and the rotating shaft 22 for rotation.

[0050] According to one embodiment of the present invention, the turning member 40 includes two turning claws 41 and a turning shaft 44 .

[0051] Specifically, two flip claws 41 are mounted side by side on the base 10. An electromagnetic base 42 is also mounted on the base 10. An electromagnet 43 is mounted on the electromagnetic base 42. The electromagnet 43 and the flip claws 41 work together to drive the print medium 60 along the flip claws 41. A flip shaft 44 is connected to the two flip claws 41, and each flip claw 41 is pivotable about the flip shaft 44. Each flip claw 41 has a ⌚-shaped cross-section with an upward opening, and each flip claw 41 is positioned between the belts 23.

[0052] In other words, if Figure 2As shown, the flip member 40 primarily consists of two flip claws 41 and a flip shaft 44. The two flip claws 41 are mounted side by side on the base 10. The two flip claws 41 form a guide ramp for the print medium 60. An electromagnetic base 42 is mounted on the base 10, and an electromagnet 43 is mounted on the electromagnetic base 42. The electromagnet 43 and the flip claws 41 work together to lift the print medium 60 along the flip claws 41 and onto the conveyor mechanism 210. A flip shaft 44 is connected to the two flip claws 41, and each flip claw 41 can pivot about the flip shaft 44. The drive motor 31 drives the flip shaft 44, which in turn causes the flip claws 41 to flip. A limit shaft 45 is also provided on the flip member 40 to limit the pivot angle of the flip claws 41. Each flip claw 41 has a ⌚-shaped cross-section with an open end facing upward, and each flip claw 41 is located between the belts 23. The electromagnet 43 can be a normally closed type.

[0053] In some embodiments of the present invention, see Figure 2 The flip mechanism 100 further includes a plurality of detection members 50, which are respectively disposed on the first base 11 and the second base 12. Each detection member 50 includes a mounting base 51 and a sensor 52. The mounting base 51 is disposed on the base 10, and the sensor 52 is disposed on the mounting base 51. The sensor 52 is used to detect the transport position of the printing medium 60 on the base 10.

[0054] In summary, according to the flipping mechanism 100 of the double-sided printing device for ID cards in an embodiment of the present invention, a flipping member 40 is provided on the base 10, and the printing medium 60 is fed into the transmission mechanism 210 of the printing device through the flipping member 40.
