[0003] The cantilever inkjet printer uses a single-sided supported cantilever mechanism to install the inkjet head. One end of the cantilever beam is installed on the frame through a set of cantilever guide rail components, and the other end is directly suspended outside the frame to form a cantilever beam structure. It can print without considering the actual width of books and account books waiting to be printed, and can move back and forth along the guide rail under the action of the drive device. At the same time, because the length of the cantilever beam suspended outside the frame is long enough, the printing area of the cantilever beam inkjet printer is entirely located outside the frame, and the objects to be printed can be inkjet printed on the built-in printing table, other printing stations or separate objects.

[0004] However, in the prior art, the cantilever inkjet printer is driven by only one driving device, and the cantilever beam is supported by a guide support member spaced apart from the driving device. Under this structure, when the cantilever beam is long, the cantilever beam is prone to deflection when being moved by a single driving device, causing the moving structure to loosen and the cantilever beam to tilt.

[0031] The present invention will be described in further detail below through specific embodiments in conjunction with the accompanying drawings.

[0032] See Figure 1 、 Figure 2 The cantilever inkjet printer provided in this embodiment includes a frame 100, a cantilever printing mechanism 200 and a displacement mechanism 300.

[0033] One side of the frame 100 extends outward and is provided with a bearing surface for placing items to be printed. The bearing surface is provided with a cantilever printing mechanism 200, which is disposed on the frame 100 and located above the bearing surface. The cantilever printing mechanism 200 includes a cantilever 210, a first drive assembly 220, and a printing assembly 230. The cantilever 210 extends horizontally, and the first drive assembly 220 is disposed on the cantilever 210. The driving direction of the first drive assembly 220 is the same as the extension direction of the cantilever 210. The printing assembly 230 is disposed on the cantilever 210 and is in transmission connection with the first drive assembly 220.

[0034] In addition, the displacement mechanism 300 is arranged on the frame 100. The displacement mechanism 300 includes a second drive component and a moving part. The second drive component is arranged on the frame 100. The moving part is transmission-connected to the second drive component. The moving part is connected to and supports the cantilever 210 mechanism. The driving direction of the second drive component is horizontal and perpendicular to the extension direction of the cantilever 210 mechanism. There are multiple displacement mechanisms 300, and the multiple displacement mechanisms 300 are arranged at intervals along the extension direction of the cantilever 210 mechanism.

[0035] Specifically, in this embodiment, the cantilever printing mechanism 200 is disposed on the frame 100, and the first drive assembly 220 drives the printing assembly 230 to move along the extension direction of the cantilever 210. The driving direction of the second drive assembly is perpendicular to the driving direction of the first drive assembly 220. Under the connection of the moving parts, the cantilever 210 can be moved in a direction perpendicular to the cantilever 210. The moving parts in the multiple displacement mechanisms 300 in this embodiment are respectively connected to different positions of the cantilever 210. When the cantilever 210 is driven to move, the multiple second drive assemblies and the moving parts are driven synchronously, thereby achieving multi-position support and multi-point synchronous movement of the cantilever 210, avoiding the cantilever 210 from swinging during movement, and further preventing the loosening of the moving structure and tilting of the cantilever 210 after long-term use.

[0036] In this embodiment, the second driving assembly includes a driving motor 310 and a screw rod 320. The driving motor 310 is disposed on the frame 100. The screw rod 320 is in transmission connection with the driving motor 310, and the moving part is disposed on the screw rod 320.

[0037] Among them, the driving shaft of the driving motor 310 in this embodiment is connected to the screw rod 320, and a threaded hole is provided on the moving part. The moving part is threadedly engaged with the screw rod 320 through the threaded hole, so that when the driving shaft rotates, the moving part can move along the extension direction of the screw rod 320, thereby realizing the movement of the cantilever 210 along the extension direction of the screw rod 320.

[0038] In this embodiment, the displacement mechanism 300 further includes a guide member. A guide portion is provided on the frame 100, and the guide portion extends in the same direction as the screw rod 320. The guide member is connected to the moving member, and the guide member is provided on the guide portion and moves along the extending direction of the guide portion.

[0039] The guide portion cooperates with the guide member to guide the movement direction of the suspension beam, further strengthening the limitation of the movement direction of the suspension beam, and realizing auxiliary support and position limiting of the suspension beam. This can effectively prevent the screw rod 320 from being deformed due to excessive force when the weight of the suspension beam is too heavy, causing the movement direction of the suspension beam to deviate from the preset direction.

[0040] Specifically, the guide portion in this embodiment is a guide rail 330 , and the guide member is a slider. The guide rail 330 is arranged parallel to the screw rod 320 . The slider is arranged on the guide rail 330 .

[0041] The guide rail 330 and the slider in this embodiment are dovetail-shaped structures that match each other, thereby improving the guiding effect between the guide rail 330 and the slider. In addition, with this structure, the slider can slide more stably on the guide rail 330, preventing the cantilever 210 from shaking during movement.

[0042] In this embodiment, there are two displacement mechanisms 300 , which are respectively disposed at two ends of the frame 100 , and the driving motor 310 , the lead screw 320 , and the guide rail 330 are all disposed on the side walls of the frame 100 .

[0043] The two displacement mechanisms 300 enable dual-point support and actuation of the cantilever 210. When the cantilever 210 moves perpendicular to its extension direction, the second drive components in the two displacement mechanisms 300 operate synchronously, providing the cantilever 210 with two actuation points during movement. This prevents the cantilever 210 from deflecting or swaying due to its excessive length, thereby preventing the support and movement structures of the cantilever 210 from loosening after prolonged use.

[0044] In this embodiment, the ratio of the length of the cantilever printing mechanism 200 located on the frame 100 to the length extending outside the frame 100 is 0.5 to 0.75.

[0045] Under this ratio, the cantilever 210 is long enough to extend outside the frame 100, and can also ensure that the cantilever 210 can move smoothly when driven by the displacement component.

[0046] Specifically, in this embodiment, the ratio of the length located on the frame 100 of the cantilever inkjet printer to the length extending outside the frame 100 is 3:4. Under this structure, the cantilever 210 has excellent stability, and the extended length is sufficient to meet the printing requirements of most items.

[0047] In this embodiment, the cantilever inkjet printer further includes a controller, which is disposed on the frame 100 and is electrically connected to the cantilever printing mechanism 200 and the displacement mechanism 300.

[0048] The controller can store printing information and control the cantilever printing mechanism 200 and the displacement mechanism 300. When printing, the controller can execute corresponding printing steps according to the user's stored content, and can drive the second drive components in multiple displacement mechanisms 300 to operate synchronously, thereby ensuring multi-position support and multi-point synchronous movement of the cantilever 210, and avoiding the cantilever 210 from swinging during the movement.

[0049] In this embodiment, a plurality of adjustable feet are provided at the bottom of the rack 100. The plurality of adjustable feet are evenly provided at the bottom of the rack 100.

[0050] When the cantilever inkjet printer is to print different items, the adjustable feet can be adjusted so that the height of the frame 100 can meet the printing requirements of the current items.

[0051] In this embodiment, the frame 100 has an extended support portion 110 . The extended support portion 110 is located below the supporting surface and at the bottom end of the frame 100 .

[0052] The extended support portion 110 is an outward-extending structure extending to the bottom of the load-bearing surface. When the printing assembly 230 moves above the load-bearing surface or extends outward from the load-bearing surface away from the frame 100, the extended support portion 110 can support the printing assembly 230, the cantilever 210, and the displacement assembly, so that the frame 100 can maintain balance and will not fall over due to the extension of the cantilever 210 or the excessive weight of the printing assembly 230.

[0053] The inkjet printing production line provided in this embodiment includes a cantilever inkjet printer.

[0054] The cantilever printing mechanism 200 is driven on the frame 100 by a first drive assembly 220 to achieve movement along the extension direction of the cantilever 210. The second drive assembly cooperates with the moving member to enable the cantilever 210 to move in a direction perpendicular to the cantilever 210. Multiple second drive assemblies and moving members are driven synchronously to achieve multi-position support and multi-point synchronous movement of the cantilever 210, thereby preventing the cantilever 210 from swaying during movement, thereby preventing the loosening of the moving structure and the tilting of the cantilever 210 after long-term use.

[0055] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will appreciate that modifications may be made to the technical solutions described in the aforementioned embodiments, or that some or all of the technical features therein may be replaced with equivalents. Such modifications or replacements do not deviate from the essence of the corresponding technical solutions within the scope of the present invention.
