[0023] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0024] It is understandable that, referring to Figures 1 to 3The printing rotation mechanism of the first embodiment of the present invention includes a frame 100, a first movable assembly 200 and a second movable assembly 300; the first movable assembly 200 includes a first movable frame 210, a first supporting frame 220 and a first driving member 230, the first movable frame 210 is slidably connected to the frame 100, the first supporting frame 220 is fixedly connected to the first movable frame 210, and the first driving member 230 is used to drive the first movable frame 210 to slide on the frame 100; the second movable assembly 300 includes a second movable frame 310, a second supporting frame 320, and a second driving member 330. 0 and the third driving member 340, the second mobile frame 310 is slidably connected to the frame 100, the second driving member 330 is arranged on the second mobile frame 310, the second supporting bracket 320 is connected to the movable end of the second driving member 330, the second driving member 330 is used to drive the second supporting bracket 320 to move up and down, and the third driving member 340 is used to drive the second mobile frame 310 to slide on the frame 100; wherein, the first supporting bracket 220 and the second supporting bracket 320 are both used to support documents, and the moving paths of the first supporting bracket 220 and the second supporting bracket 320 overlap in projection on the frame 100.

[0025] The first support bracket 220 is fixedly connected to the first mobile frame 210, which is slidably connected to the frame 100. The first mobile frame 210 is driven to slide on the frame 100 by the first driving member 230, thereby driving the first support bracket 220 to move, thereby enabling automatic document loading. The second support bracket 320 is connected to the movable end of the second driving member 330, which is connected to the second mobile frame 310. The second mobile frame 310 is slidably connected to the frame 100, so that the second driving member 330 can drive the second support bracket 320 to move up and down. The third driving member 340 can drive the second mobile frame 310 to slide on the frame, thereby enabling automatic document loading. By setting the projections of the moving paths of the first supporting bracket 220 and the second supporting bracket 320 on the frame 100 to overlap, when the first supporting bracket 220 and the second supporting bracket 320 slide toward each other on the frame 100, the second supporting bracket 320 can be driven to move up and down by the second driving member 330, so that the second supporting bracket 320 can avoid the first supporting bracket 220, so that the first supporting bracket 220 and the second supporting bracket 320 can cooperate to continuously transport the documents, realize continuous printing of the documents, reduce the waiting time of the printing mechanism 420, and improve printing efficiency.

[0026] The feeding mechanism 410 is disposed on one side of the frame 100 and is used to feed documents to the first support bracket 220 and the second support bracket 320. First, the first support bracket 220 and the second support bracket 320 are located at opposite ends of the frame 100, and the second driving member 330 drives the second support bracket 320 downward, so that the second support bracket 320 is located below the first support bracket 220. The document is fed to the first support bracket 220 through the feeding mechanism 410, and then the first driving member 230 drives the first movable frame 210 to slide on the frame 100, so that the first support bracket 220 can move into the working range of the printing mechanism 420, so that the printing mechanism 420 can print the document on the first support bracket 220; at the same time, the third driving member 340 drives the second movable frame 310 to slide on the frame 100, and the second driving member 330 drives the second support bracket 320 to rise, so that the feeding mechanism 410 can feed the document to the second support bracket 320 Finally, the second driving member 330 drives the second supporting bracket 320 to descend, and the third driving member 340 drives the second movable frame 310 to slide on the frame 100, and the first driving member 230 drives the first movable frame 210 to slide on the frame 100, so that the positions of the first supporting bracket 220 and the second supporting bracket 320 are rotated, and the second driving member 330 drives the second supporting bracket 320 to rise, so that the second supporting bracket 320 can move into the working range of the printing mechanism 420, so that the printing mechanism 420 can print the document on the second supporting bracket 320.

[0027] By cooperating with the first driving member 230, the second driving member 330 and the third driving member 340, the positions of the first supporting bracket 220 and the second supporting bracket 320 can be rotated, so that when the certificate on the first supporting bracket 220 is printed, the material can be loaded onto the second supporting bracket 320, so that the first supporting bracket 220 and the second supporting bracket 320 can be rotated on the frame 100, thereby realizing continuous printing of the certificate, reducing the waiting time, and improving printing efficiency.

[0028] It should be noted that the width of the first movable frame 210 is greater than the width of the second supporting frame 320, so that after the second driving member 330 drives the second supporting frame 320 to descend, the third driving member 340 can drive the second supporting frame 320 to move below the first movable frame 210, so that the projections of the moving paths of the first supporting frame 220 and the second supporting frame 320 on the frame 100 overlap, which can reduce the occupied area of ​​the frame 100, make the print rotation mechanism structure compact, and shorten the moving distance of the first supporting frame 220 and the second supporting frame 320, thereby improving the efficiency of position rotation.

[0029] In addition, the first driving member 230 , the second driving member 330 , and the third driving member 340 can be linear cylinders, electric push rods, linear slide modules, etc., which are not limited here.

[0030] Specifically, refer to Figure 1 Two second driving members 330 are provided, one on each side of the second movable frame 310, and the movable ends of the two second driving members 330 are connected to the second supporting frame 320. The two second driving members 330 can synchronously drive the second supporting frame 320 to move up and down, thereby stabilizing the force applied to the second supporting frame 320, improving the smoothness of the movement of the second supporting frame 320, reducing the possibility of document skew, and improving printing stability.

[0031] It is understandable that, referring to Figures 2 to 4 The second movable assembly 300 further includes a buffer component 350, which includes a connecting block 351, a first buffer 352, and a second buffer 353. The connecting block 351 is fixedly connected to the second supporting bracket 320, the first buffer 352 is fixedly connected to the second movable frame 310, and the second buffer 353 is fixedly connected to the connecting block 351. The connecting block 351 can abut against the first buffer 352, and the second buffer 353 can abut against the second movable frame 310. The connecting block 351 is fixedly connected to the second supporting bracket 320, the first buffer 352 is arranged on the second movable frame 310, and the second buffer 353 is arranged on the connecting block 351. When the second driving member 330 drives the second supporting bracket 320 to rise, the connecting block 351 can abut against the first buffer 352; when the second driving member 330 drives the second supporting bracket 320 to descend, the second buffer 353 can abut against the second movable frame 310, thereby limiting the range of motion of the second supporting bracket 320 by the first buffer 352 and the second buffer 353, stabilizing the position of the second supporting bracket 320 and improving the stability and accuracy of printing.

[0032] Furthermore, the first and second buffers 352 and 353 absorb any impact or vibration encountered by the second support bracket 320 during its lifting motion. This effectively absorbs and disperses the impact of the second support bracket 320's movement, reducing the impact of mechanical motion on the document, ensuring document stability and improving print quality. Furthermore, the buffer components 350 extend the life of the mechanism, reducing mechanical wear and failure caused by frequent impacts, and enhancing the reliability of the entire print rotation mechanism.

[0033] It is understandable that, referring to Figure 1The first driving member 230 includes a first screw rod 231, a first movable block 232, and a first motor (not shown in the drawings). The first screw rod 231 is rotatably connected to the frame 100, and the first movable block 232 is fixedly connected to the first movable frame 210. The first movable block 232 and the first screw rod 231 are threadedly connected. The first motor is used to drive the first screw rod 231 to rotate. The first movable block 232 is sleeved on the first screw rod 231 and is threadedly connected to the first screw rod 231. The first motor drives the first screw rod 231 to rotate, which can accurately control the axial movement of the first movable block 232 along the first screw rod 231, thereby driving the first movable frame 210 to slide precisely on the frame 100, allowing the first movable frame 210 to move stably on the frame 100, facilitating the loading of documents and improving the stability of the rotation.

[0034] Among them, by setting the first screw rod 231 and the first movable block 232 to be threadedly connected, the first movable block 232 can be self-locked on the first screw rod 231 through the thread, which can prevent the position of the first movable block 232 from shifting and improve the position stability of the first movable frame 210.

[0035] In addition, the first motor mentioned above can also be replaced by a pneumatic motor, which will not be described in detail here.

[0036] Specifically, refer to Figure 1 The number of the first screw rods 231 and the first movable block 232 is set to be multiple, and the multiple first screw rods 231 are arranged in parallel and spaced apart, and the first screw rods 231 and the first movable blocks 232 are in one-to-one correspondence. The multiple first screw rods 231 are arranged in parallel and spaced apart on the frame 100, and the multiple first movable blocks 232 are fixedly connected to the first movable frame 210. By setting the first screw rods 231 and the first movable blocks 232 in one-to-one correspondence, the first movable frame 210 is subjected to multiple support points during the sliding process, effectively dispersing the load, avoiding structural deformation or poor sliding caused by single-point force, and reducing errors caused by unstable sliding, thereby improving the loading accuracy and printing quality of the document.

[0037] It should be noted that the width of the first movable frame 210 is greater than the width of the second supporting frame 320. By respectively arranging the first movable blocks 232 on both sides of the first movable frame 210, the two first screw rods 231 and the two first movable blocks 232 cooperate to stabilize the force on the first movable frame 210, avoid the movement deviation of the first movable frame 210, and improve the smoothness of the rotation.

[0038] Specifically, refer to Figure 1The first screw rod 231 is fixedly connected to a synchronous wheel 233, and the multiple synchronous wheels 233 are transmission-connected via a synchronous belt 234. The first motor is used to drive one of the synchronous wheels 233 to rotate. Each first screw rod 231 is fixedly connected to a synchronous wheel 233, and the multiple synchronous wheels 233 cooperate with the tensioned synchronous belt 234 to enable the synchronous wheels 233 to be transmission-connected to the synchronous belt 234. The first motor drives one of the synchronous wheels 233 to rotate, which not only reduces the number of drive sources and reduces costs, but also enables the multiple first screw rods 231 to rotate synchronously, thereby improving the motion stability of the first movable frame 210, avoiding synchronization errors that may be caused by the independent driving of multiple motors, and improving the reliability of the first movable assembly 200. It is understandable that, referring to Figure 2 The third driving member 340 includes a second screw rod 341, a second movable block 342, and a second motor (not shown in the drawings). The second screw rod 341 is rotatably connected to the frame 100, and the second movable block 342 is fixedly connected to the second movable frame 310. The second movable block 342 and the second screw rod 341 are threadedly connected. The second motor is used to drive the second screw rod 341 to rotate. By driving the second motor to rotate the second screw rod 341, the second movable block 342 can be precisely controlled to move axially along the second screw rod 341, thereby driving the second movable frame 310 to slide precisely on the frame 100, allowing the second movable frame 310 to move stably on the frame 100, facilitating document loading and improving rotation stability.

[0039] Among them, by setting the second screw rod 341 and the second movable block 342 to be threadedly connected, the second movable block 342 can be self-locked on the second screw rod 341 through the thread, which can prevent the position of the second movable frame 310 from shifting and improve the position stability of the second movable block 342.

[0040] It is understandable that, referring to Figure 1 The frame 100 is fixedly connected to a first guide rail 111 and a second guide rail 112. The first guide rail 111 and the second guide rail 112 are arranged in parallel. The first movable frame 210 is fixedly connected to a first slider 113, and the second movable frame 310 is fixedly connected to a second slider 114. The first slider 113 is slidably connected to the first guide rail 111, and the second slider 114 is slidably connected to the second guide rail 112. The first guide rail 111 and the second guide rail 112 are arranged in parallel. The first slider 113 is fixedly connected to the first movable frame 210, and the second slider 114 is fixedly connected to the second movable frame 310. By arranging the first slider 113 to be slidably connected to the first guide rail 111 and the second slider 114 to be slidably connected to the second guide rail 112, the first movable frame 210 and the second movable frame 310 can move accurately during the sliding process, avoiding positioning errors caused by poor sliding or offset, thereby improving the loading accuracy and printing quality of the documents.

[0041] In addition, the first slider 113 is slidably connected to the first guide rail 111, and the second slider 114 is slidably connected to the second guide rail 112, so that the first movable frame 210 and the second movable frame 310 can move smoothly, reduce the resistance to movement, thereby slowing down wear and extending the service life.

[0042] Specifically, refer to Figure 1 The first guide rail 111, the first slider 113, the second guide rail 112, and the second slider 114 are all provided in multiple numbers. By providing multiple numbers of the first guide rail 111, the first slider 113, the second guide rail 112, and the second slider 114, the first mobile frame 210 and the second mobile frame 310 are supported and guided in multiple directions during the sliding process, effectively dispersing the load and avoiding structural deformation or poor sliding caused by single-point force, thereby improving document loading accuracy and printing quality.

[0043] It is understandable that, referring to Figure 1 The frame 100 is fixedly connected to two buffer blocks 120, which are arranged at both ends of the frame 100. The second movable frame 310 can abut against the buffer blocks 120. The two buffer blocks 120 are respectively arranged at both ends of the frame 100. By setting the second movable frame 310 to abut against the buffer blocks 120, the movement position of the second movable frame 310 can be limited, thereby improving the operating accuracy and reliability of the mechanism, and absorbing its impact energy, avoiding direct collision between the second movable frame 310 and the frame 100, thereby protecting the mechanism from damage.

[0044] In addition, two other buffer blocks 120 may be provided at both ends of the frame 100 so that the first movable frame 210 can abut against the other two buffer blocks 120 to limit the movement position of the first movable frame 210 and improve the movement stability of the first movable frame 210 .

[0045] It should be noted that the buffer block 120 can be an elastic element such as a rubber part, a silicone part, etc., which will not be described in detail here.

[0046] It is understandable that, referring to Figures 2 to 5 The automated printing equipment of the second embodiment of the present invention includes a feeding mechanism 410, a printing mechanism 420 and a printing rotation mechanism of the first embodiment of the present invention. The feeding mechanism 410 is used to transport documents to the first supporting bracket 220 and the second supporting bracket 320, and the printing mechanism 420 is used to print documents.

[0047] The feeding mechanism 410 is arranged on one side of the frame 100, and the first supporting bracket 220 and the second supporting bracket 320 are respectively arranged at both ends of the frame 100. The document can be fed to the first supporting bracket 220 through the feeding mechanism 410, and then the first driving member 230 drives the first movable frame 210 to slide on the frame 100, so that the first supporting bracket 220 can move to the printing mechanism 420, so that the printing mechanism 420 prints the document on the first supporting bracket 220; at the same time, the second driving member 330 drives the second supporting bracket 320 to descend, and the third driving member 340 drives the second movable frame 310 to slide on the frame 100, so that the second supporting bracket 320 moves to the feeding mechanism 4 10, the second driving member 330 drives the second supporting bracket 320 to rise, so that the feeding mechanism 410 can convey the document to the second supporting bracket 320; then the first driving member 230, the second driving member 330 and the third driving member 340 cooperate to rotate the positions of the first supporting bracket 220 and the second supporting bracket 320, so that when the printing mechanism 420 prints the document on the first supporting bracket 220, the feeding mechanism 410 can convey the document to the second supporting bracket 320. By rotating the positions of the first supporting bracket 220 and the second supporting bracket 320, the stopping and waiting time of the feeding mechanism 410 and the printing mechanism 420 can be reduced, so that the printing process is coherent and the printing efficiency is improved.

[0048] 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 knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
