[0029] Reference Figure 1 、 Figure 2 and Figure 3 The present invention provides a certificate flipping mechanism, comprising a frame 100, a flipping device 300, and an output device 400. The flipping device 300 is connected to the frame 100 and specifically comprises a bracket 310, a drive assembly 330, and a rotating assembly 320. The bracket 310 is connected to the frame 100, and the rotating assembly 320 is rotatably connected to the bracket 310. The drive assembly 330 is used to drive the rotating assembly 320 to rotate, and the rotating assembly 320 is used to obtain and drive a single certificate 500 to flip. The output device 400 is connected to the frame 100 and is located on one side of the flipping device 300. The output device 400 includes an output belt 440, on which are provided a plurality of sets of positioning blocks 450. Each set of positioning blocks 450 defines a slot 451 to accommodate a certificate 500 in a horizontal position.

[0030] Specifically, the frame 100, serving as the support structure for the entire flipping mechanism, is made of durable metal, offering sufficient strength and stability. Optionally, fixed feet are provided at the bottom of the frame 100 to ensure stability during operation. Furthermore, the flipping device 300 comprises a bracket 310, a drive assembly 330, and a rotating assembly 320. The bracket 310 is fixedly connected to the frame 100, while the rotating assembly 320 is rotatably connected to the bracket 310 via bearings and other components. The drive assembly 330 utilizes a power source, such as a motor, to drive the rotating assembly 320 through a transmission mechanism. The rotating assembly 320 is equipped with a slot 324 designed to match the dimensions of a certificate 500, ensuring accurate gripping and flipping of the certificate 500 as it passes through. The output device 400 is connected to the other end of the frame 100 and is located on one side of the flipping device 300. The output device 400 comprises an output belt 440 and multiple sets of positioning blocks 450 mounted on the output belt 440. A slot 451 is formed between each set of positioning blocks 450 , and the size of the slot 451 matches the horizontally placed certificate book 500 after flipping over to ensure that the certificate book 500 maintains a stable horizontal position during the output process.

[0031] It should be noted that by optimizing the structure of the flipping device 300 and the output device 400, the entire flipping mechanism has a compact structure and occupies a small area. At the same time, it can adapt to certificates 500 of different sizes and thicknesses, thereby improving the versatility and flexibility of the equipment. The entire flipping process is fully automated and requires no human intervention, which greatly improves the efficiency and accuracy of the certificate 500 processing and reduces labor costs. The flipping device 300 uses a precise combination of the drive component 330 and the rotating component 320 to ensure the stability and accuracy of the certificate 500 during the flipping process, effectively avoiding the occurrence of problems such as card jams and misalignment, and improving the flipping efficiency and quality. On the other hand, the flipping mechanism is rationally designed, with tight connections between the various components, making it easy to disassemble and replace, thereby reducing the maintenance cost and failure rate of the equipment.

[0032] Reference Figure 1 and Figure 2 It should be noted that the frame is also equipped with a conveyor device 200, which is connected to one end of the frame 100 and is used to transport the upright certificates 500 one by one. Optionally, the conveyor device 200 uses a conveyor belt with spaced-apart blocks to ensure that the certificates 500 remain upright during transportation and are separated one by one. The output device 400 is located on the side of the flipping device 300 facing away from the conveyor device 200.

[0033] In other embodiments, the flipping device 300 is located at the output end of the conveying device 200, and includes a bracket 310, a drive assembly 330, and a rotating assembly 320. The bracket 310 is fixedly connected to the frame 100, and the rotating assembly 320 is rotatably connected to the bracket 310 through bearings and other components. The drive assembly 330 uses a power source such as a motor to drive the rotating assembly 320 to rotate through a transmission mechanism such as a gear or chain. The rotating assembly 320 is provided with a clamping mechanism that matches the size of the certificate book 500, which is used to accurately clamp the certificate book 500 when it passes and drive it to flip. The clamping mechanism can be a pneumatic clamping claw or a suction cup to fix a single certificate book 500 and drive it to flip and be horizontal.

[0034] Reference Figure 2 Specifically, the rotating assembly 320 includes a roller 321 and a fixed seat 322. The roller 321 is rotatably connected to the bracket 310 through bearings and other components to ensure smooth rotation. The fixed seat 322 is connected to the side wall of the roller 321. Each fixed seat 322 includes two oppositely arranged clamping plates 323. A certificate slot 324 is formed between the two clamping plates 323. The size of the slot 324 is slightly larger than the thickness of the certificate 500 to ensure that the certificate 500 can be firmly embedded therein without being too tight or too loose. When the roller 321 rotates, the fixed seat 322 moves accordingly, thereby causing the certificate 500 embedded therein to flip.

[0035] In some embodiments, four fixed seats 322 are provided, and the four fixed seats 322 are evenly spaced along the circumference of the roller 321. In this way, during the rotation of the roller 321, each fixed seat 322 can pass through the output end of the conveying device 200 in sequence, thereby achieving continuous flipping of the certificate book 500. In other embodiments, one fixed seat 322 can be provided, and the drive assembly 330 drives the roller 321 to rotate forward and backward to achieve reciprocating movement of the certificate book slot 324 between the output end of the conveying device 200 and the output device 400, thereby continuously completing the acquisition, flipping, and placement of the certificate book 500. In other embodiments, two or more fixed seats 322 can be provided, and the speed at which the drive assembly 330 drives the roller 321 to rotate is matched to the speed at which the conveying assembly outputs the certificate book 500. The number of fixed seats 322 is not limited here.

[0036] It should be noted that the spacing of the certificate slot 324, i.e., the distance between the two clamping plates 323, should be slightly larger than the thickness of the certificate book 500, but no more than 120% of its thickness, to ensure that the certificate book 500 can be easily inserted without shaking. Furthermore, the height of the clamping plates 323, i.e., the distance from the top of the clamping plates 323 to the bottom of the fixing base 322, should be at least 30% of the width of the certificate book 500 to ensure that the certificate book 500 can maintain a stable posture during the flipping process.

[0037] It should be noted that, in some embodiments, both ends of the splint 323 are provided with chamfers, which are located on opposite sides of the two splints 323 and form flares to facilitate the certificate book 500 to be smoothly inserted into the certificate book slot 324 and flipped.

[0038] Reference Figure 1 and Figure 2 The bracket 310 is provided with a receiving groove 311, and the roller 321 is located in the receiving groove 311. The roller 321 is rotatably connected to the receiving groove 311 by its rotating shaft 3211 passing through the through holes in the groove walls on both sides of the bracket 310. The drive assembly 330 is located on one side of the bracket 310, and its output end is connected to the rotating shaft 3211 through a coupling or directly to drive the roller 321 to rotate.

[0039] Reference Figure 2 In a specific embodiment, the drive assembly 330 is driven by a motor. Specifically, a first motor 331 drives a first driving pulley 332 to rotate. The first driving pulley 332 is connected to a first transmission pulley 333 via a belt 334. The first transmission pulley 333 is connected to the rotating shaft 3211 of the drum 321. Thus, when the first motor 331 is started, the drum 321 can be driven to rotate via the belt 334.

[0040] Reference Figure 1 and Figure 3 In a specific embodiment, the output device 400 includes a second motor 410, a second driving wheel 420, a second transmission wheel 430 and an output belt 440. The second motor 410 drives the second driving wheel 420 to rotate, and multiple second transmission wheels 430 are connected to the second driving wheel 420 through the output belt 440 to form a closed-loop transmission system. The output belt 440 passes through the conveying trough 110 on the frame 100. The design of the conveying trough 110 allows the output belt 440 to maintain a horizontal state when running. The positioning block 450 is fixed to the output belt 440 and moves with the movement of the output belt 440 to receive and transmit the flipped certificate 500. The output device 400 adopts a closed-loop transmission system and precise positioning blocks 450 and card slots 451 to ensure that the flipped certificate 500 can be stably transmitted to the designated position, avoiding dislocation and falling.

[0041] Reference Figure 3 Furthermore, a slanted wall 452 is provided on the top of the positioning block 450, which is located on the side of the positioning block 450 facing the card slot 451. This facilitates the flipped certificate 500 to slide smoothly into the card slot 451, reducing damage caused by collision.

[0042] It should be noted that the spacing range of the card slot 451, that is, the distance between the positioning blocks 450 should be slightly larger than the length of the certificate 500, but not more than 105% of its length, to ensure that the certificate 500 can be stably placed in the card slot 451 during the output process to avoid mutual squeezing or misalignment.

[0043] The present invention also provides a printing device that integrates the aforementioned certificate flipping mechanism. By integrating the certificate flipping mechanism into the printing device, the printing, flipping, transporting, and stacking of the certificate 500 are automated, significantly improving production efficiency, reducing the need for manual operation, and lowering labor costs. Furthermore, errors and losses caused by human error are avoided.

[0044] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
