Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] Please also read Figures 1 to 4 Now, the mobile inkjet stamping mechanism 100 provided in the embodiment of the present application is described. The mobile inkjet stamping mechanism 100 comprises: an inkjet module support 10, an inkjet module 20 and a downward pressing driving assembly 30.

[0036] It can be understood that the inkjet module support body 10 can support and guide the inkjet module 20. The inkjet module 20 is arranged on the inkjet module support body 10. When the downward pressure driving component 30 drives the inkjet module support body 10 to be pressed down, the inkjet module 20 can be close to the document to be stamped. After being pressed into place, the document located under the inkjet module 20 can be inkjet stamped.

[0037] The inkjet module support 10 is provided with an inkjet hole 11, a graded guide rail 12, and an inkjet head bracket 13. The graded guide rail 12 includes a first smooth section 121, an ascending section 122, a second smooth section 123, a descending section 124 and a third smooth section 125 connected in sequence.

[0038] Among them, the inkjet module 20 includes an ink cartridge assembly 21, a parallel guide rod 22 and an ink cartridge driving assembly 23. The parallel guide rod 22 is hinged to the inkjet module support body 10. The ink cartridge assembly 21 is slidably set on the parallel guide rod 22 and the bottom end is slidably set with the graded guide rail 12. The ink cartridge driving assembly 23 is connected to the ink cartridge assembly 21 and is used to drive the ink cartridge assembly 21 to reciprocate on the first smooth section, the rising section 122, the second smooth section, the descending section 124 and the third smooth section.

[0039] The downward pressing driving assembly 30 is connected to the inkjet module supporting body 10 and is used to drive the inkjet module supporting body 10 to move up and down.

[0040] It can be understood that during the stamping process, the ink cartridge assembly 21 is located on the initial end of the first smooth section 121 of the graded guide rail 12. After the downward pressure driving assembly 30 drives the inkjet module support body 10 to be pressed down into place, the ink cartridge driving assembly 23 can drive the ink cartridge assembly 21 to move slowly along the guide of the parallel guide rod 22 and the first smooth section 121 at the same time. At the same time, the inkjet module 20 starts to inkjet print the document through the inkjet hole 11 until the ink cartridge assembly 21 is translated to the end of the first smooth section 121. The downward pressure driving assembly 30 drives the inkjet module support body 10 to reset and rise, and the inkjet printing is completed, and the inkjet stamping is completed.

[0041] During the inkjet printing process, the ink cartridge drive assembly 23 provides translational traction to the ink cartridge assembly 21, and the parallel guide rod 22 and the first smooth section 121 jointly guide the ink cartridge assembly 21, wherein the parallel guide rod 22 can reduce the vibration of the ink cartridge assembly 21 in the front-to-back direction, and the first smooth section 121 can reduce the vibration of the ink cartridge assembly 21 in the up-and-down direction, so as to ensure the translational stability of the ink cartridge assembly 21 during inkjet printing and improve the inkjet printing quality.

[0042] After inkjet printing is completed, in order to prevent the ink of the inkjet head of the ink cartridge assembly 21 from drying up, the inkjet head of the ink cartridge assembly 21 can be protected by the inkjet head bracket 13.

[0043] That is, the ink cartridge driving assembly 23 continues to provide translational traction to the ink cartridge assembly 21, and the parallel guide rod 22 and the rising section 122 together guide the ink cartridge assembly 21. Since the parallel guide rod 22 is hinged to the inkjet module support body 10, when the ink cartridge assembly 21 passes through the rising section 122, one end of the parallel guide rod 22 will be lifted, so that the ink cartridge assembly 21 moves straightly and obliquely upward.

[0044] When the ink cartridge assembly 21 rises to its position, it enters the second smooth section 123. The second smooth section 123 mainly plays a buffering role, because the movement direction of the ink cartridge assembly 21 during the rising section 122 is rising, and the movement direction of the sliding section 124 is descending. Therefore, by setting the second smooth section 123 transition, the stability of the ink cartridge assembly 21 during movement can be improved, and wear and noise can be reduced.

[0045] When the ink cartridge assembly 21 moves from the second smooth section 123 to the lower sliding section 124, the ink cartridge assembly 21 moves linearly and obliquely downward, and one end of the parallel guide rod 22 will be lowered until the ink cartridge assembly 21 slides to the third smooth section 125. The ink cartridge drive assembly 23 stops driving. At this time, the inkjet head at the bottom of the ink cartridge assembly 21 is attached to the inkjet head bracket 13. The inkjet head bracket 13 is provided with a latex material layer, which can keep the inkjet head at the bottom of the ink cartridge assembly 21 moist on the one hand, and on the other hand, due to the existence of the lower sliding section 124, the movement of the ink cartridge assembly 21 can be limited without causing wear to the inkjet head at the bottom of the ink cartridge assembly 21.

[0046] When the printing mode is restarted, the ink cartridge driving component 23 drives the ink cartridge component 21 from the third smooth section 125 through the downward sliding section 124, the second smooth section 123, the upward section 122 to the first smooth section 121 in sequence, and the downward pressing driving component 30 drives the inkjet module 20 to press down to start inkjet printing, completing the inkjet printing cycle.

[0047] Compared with the prior art, the mobile inkjet stamping mechanism 100 provided in the present application has the parallel guide rod 22 and the first smooth section 121 jointly guiding the ink cartridge assembly 21 to ensure the stability of the translation of the ink cartridge assembly 21 during inkjet printing, thereby improving the quality and efficiency of inkjet printing; the parallel guide rod 22 is hinged to the inkjet module support body 10, so that the ink cartridge assembly 21 can follow the swing when passing through the ascending section 122, the second smooth section 123, the descending section 124 and the third smooth section 125, thereby further improving the stability of the ink cartridge assembly 21 during movement, reducing noise, and increasing the service life of the ink cartridge assembly 21.

[0048] In another embodiment of the present application, please refer to Figure 4 The ink cartridge driving assembly 23 includes a first power device 231 and a conveyor belt 232 . The first power device 231 is connected to the conveyor belt 232 , and the conveyor belt 232 is connected to the ink cartridge assembly 21 , so that the first power device 231 drives the ink cartridge assembly 21 through the conveyor belt 232 .

[0049] It is understandable that when the first power device 231 rotates forward, the conveyor belt 232 drives the ink cartridge assembly 21 to move rightward, and when the first power device 231 rotates reversely, the conveyor belt 232 drives the ink cartridge assembly 21 to move leftward. The first power device 231 is preferably a servo motor, which has the characteristics of fast response and high control accuracy.

[0050] Please also refer to Figure 5 The ink cartridge driving assembly 23 also includes a tensioning adjustment device 233, which includes a fixed frame 2331, a movable frame 2332 and an angle adjustment bolt 2334. The fixed frame 2331 is fixed on the parallel guide rod 22, and the movable frame 2332 is hinged to the fixed frame 2331. A fixed pulley 2335 is provided on the movable frame 2332, and the fixed pulley 2335 is connected to the conveyor belt 232. The angle adjustment bolt 2334 is connected to the fixed frame 2331 and the movable frame 2332 at the same time, and is used to adjust the angle between the fixed frame 2331 and the movable frame 2332.

[0051] It is understandable that since the conveyor belt 232 will become longer during long-term use, or due to errors in manufacturing precision, the conveyor belt 232 may be too tight or too loose, and the angle between the fixed frame 2331 and the movable frame 2332 can be adjusted by adjusting the angle adjustment bolt 2334. The larger the angle between the fixed frame 2331 and the movable frame 2332, the looser the conveyor belt 232, and the smaller the angle between the fixed frame 2331 and the movable frame 2332, the tighter the conveyor belt 232.

[0052] Please also refer to Figure 2 and Figure 5 The fixing frame 2331 is provided with a boss 2336 , and the inkjet module support body 10 is provided with a slide groove 14 , and the boss 2336 is slidably disposed in the slide groove 14 .

[0053] It can be understood that since the parallel guide rod 22 is hinged to the inkjet module support body 10, when the inkjet module 20 moves in the ascending section 122, the second smooth section 123, and the descending section 124, the tensioning adjustment device 233 will follow the swing, and the slide groove 14 can further guide the boss 2336 to limit the forward and backward deviation of the parallel guide rod 22 during the swinging process, so as to further improve the stability of the ink cartridge assembly 21 during movement.

[0054] Furthermore, a tension elastic member (not shown) is disposed on the inkjet module support body 10 , one end of the tension elastic member is fixed to the bottom end of the inkjet module support body 10 , and the other end is fixed to the tension adjustment device 233 .

[0055] It can be understood that the ink cartridge assembly 21 can be closely attached to the graded guide rail 12 by the tension elastic member, thereby ensuring the stability of the ink cartridge assembly 21 during high-speed movement, thereby improving both speed and stability.

[0056] Specifically, the tension elastic member is a tension coil spring.

[0057] In another embodiment of the present application, please refer to Figure 2 A pair of positioning shaft blocks 15 are provided on the inkjet module support body 10 , one end of the parallel guide rod 22 is located between the pair of positioning shaft blocks 15 , and one end of the parallel guide rod 22 is hinged to the pair of positioning shaft blocks 15 , respectively.

[0058] It is understandable that the positioning pillow block 15 can be provided with a detachable cover. When the cover is opened, one end of the parallel guide rod 22 can be inserted into the positioning pillow block 15. When the cover is closed, one end of the parallel guide rod 22 can be fixed in the positioning pillow block 15.

[0059] In another embodiment of the present application, please refer to Figure 6 The ink cartridge assembly 21 includes an ink cartridge body 211, an ink cartridge mounting frame 212, a bearing 213 and a sleeve 214. The ink cartridge body 211 is installed in the ink cartridge mounting frame 212. The bearing 213 is arranged at the bottom of the ink cartridge mounting frame 212, and the bearing 213 is sleeved on the parallel guide rod 22. The sleeve 214 is arranged at the bottom of the ink cartridge mounting frame 212, and the sleeve 214 is slidably connected to the graded guide rail 12.

[0060] It can be understood that the ink cartridge mounting bracket 212 can be used to mount and position the ink cartridge body 211 , and the bearing 213 and the sleeve 214 can reduce the friction coefficient, reduce wear, and increase service life and stability.

[0061] In another embodiment of the present application, please refer to Figure 2 , Figure 7 and Figure 8 The downward pressure driving assembly 30 includes a second power device 31, a cam 32 and a guide rail 33. The inkjet module support body 10 is provided with a special-shaped hole 16. The second power device 31 is connected to the cam 32. The cam 32 is located in the special-shaped hole 16. The inkjet module support body 10 is slidably connected to the guide rail 33.

[0062] It can be understood that the second power device 31 can drive the cam 32 to rotate. When the protruding end of the cam 32 swings upward, the inkjet module support body 10 moves upward along the guide rail 33. When the protruding end of the cam 32 swings downward, under the action of gravity, the inkjet module support body 10 moves downward along the guide rail 33. This can prevent the motor from getting out of control and the ink cartridge assembly 21 from being pressed down too much, resulting in damage to the inkjet head and the document to be inkjet printed.

[0063] See also Figure 1 and Fig. 9 The present application also provides an automatic stamping machine 200, which includes a housing 201, a cursor device 202 and the mobile inkjet stamping mechanism 100 as described above, wherein the housing 201 is provided with an observation hole 2011, and the cursor device 202 and the mobile inkjet stamping mechanism 100 are arranged in the housing 201.

[0064] The emitting direction of the cursor device 202 is directly facing the inkjet hole 11 , and the cursor device 202 can project the inkjet printing picture in proportion.

[0065] It is understandable that, since the emitting direction of the cursor device 202 is facing the inkjet hole 11, the user can view the projection of the cursor device 202 through the observation hole 2011, and then adjust the position of the document to be inkjet printed according to the position of the projection in the document to be inkjet printed, so as to achieve accurate inkjet printing and preview. Transparent glass or plastic can be set at the observation hole 2011 to prevent dust from entering.

[0066] It is worthwhile to explain that the cursor device 202 can be connected to a computer host, so as to obtain an inkjet printing screen in advance, and the inkjet printing screen is projected onto the style in the document to be inkjet printed, that is, the pattern to be printed.

[0067] Compared with the prior art, the automatic stamping machine 200 provided in the present application uses a cursor device 202 to mark the inkjet printing area, which facilitates the user to accurately adjust the printing position and preview.

[0068] In another embodiment of the present application, please refer to Fig. 9 The automatic stamping machine 200 further includes a bottom plate 203 , which is disposed below the inkjet hole 11 . The bottom plate 203 is provided with a ramp plate 204 , which is hinged to the bottom plate 203 .

[0069] It can be understood that the document to be printed can be slid onto the bottom plate 203 through the ramp plate 204 to wait for inkjet printing and stamping, and the bottom area of ​​the bottom plate 203 is increased by the ramp plate 204, making the placement more stable. Since the ramp plate 204 is hinged to the bottom plate 203, the ramp plate 204 can be hidden under the bottom surface of the bottom plate 203 for easy transportation.

[0070] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
