Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, specifically to a flatbed-cylindrical integrated printing device. Background Technology

[0002] In recent years, with the rapid development of digital printing technology, its applications have expanded from traditional paper to various flat and curved objects. Against this backdrop, composite printing equipment that combines flatbed and cylindrical printing functions has emerged to meet the diverse market demands for personalized surface decoration of products.

[0003] Existing flatbed / cylindrical all-in-one printers typically switch between two modes via a height-adjustable or movable printing platform. In flatbed printing mode, the platform serves as the workpiece support plane; in cylindrical printing mode, the platform transforms into a roller structure that drives the product's rotation. However, such equipment has significant limitations in cylindrical printing. Currently, mainstream equipment can only print a single cylindrical product at a time, resulting in low production efficiency and difficulty in meeting the demands of batch processing. Furthermore, for cylindrical products of varying lengths, the equipment often lacks effective and adaptable limiting and fixing structures. This leads to axial movement of the product during rotation when printing slender or short products, affecting printing accuracy and even causing product scrap.

[0004] Therefore, it is particularly urgent to develop a new type of integrated flatbed and cylindrical printing equipment that can efficiently and stably complete flatbed and cylindrical printing tasks, and has batch processing capabilities and a flexible limiting and fixing structure.

[0023] This embodiment provides a flatbed cylindrical integrated printing device, referring to... Figures 1-6The system includes a body 10, a printing platform 20, a printhead assembly 30, and a cylindrical printing module 40. The printing platform 20 is used to carry flatbed printing media or cylindrical printing media 200, and includes a first table 21 and a second table 22 arranged adjacent to each other. The second table 22 has a receiving groove 221. The printhead assembly 30 is slidably disposed above the printing platform 20 and is used to print the flatbed printing media or cylindrical printing media 200 on the printing platform 20. The cylindrical printing module 40 is disposed in the receiving groove 221 and includes a fixed frame 41 fixedly disposed in the receiving groove 221, at least two drive rollers 42 arranged side by side on the fixed frame 41 and capable of rotating synchronously, and multiple sets of axial limiting components 43 slidably disposed on the fixed frame 41. The multiple sets of axial limiting components 43 are arranged along the axial direction of the drive rollers 42 to form multiple cylindrical printing stations 44 for placing cylindrical printing media 200 in the axial direction of the drive rollers 42. At least one set of axial limiting components 43 is configured to be locked in different positions on the fixed frame 41 to adjust the distance between adjacent axial limiting components 43.

[0024] During cylindrical printing, the drive roller 42 carries and drives the cylindrical printing medium 200 to rotate, enabling the print head assembly 30 to perform comprehensive and precise printing on the cylindrical printing medium 200. Through at least two drive rollers 42 arranged side-by-side and rotating synchronously, and multiple sets of sliding and locking axial limiting components 43, multiple independent cylindrical printing stations 44 are formed in the axial direction of the drive rollers 42. This achieves synchronous printing of multiple cylindrical printing media 200, greatly improving production efficiency. Simultaneously, by adjusting the spacing between adjacent axial limiting components 43, it can accommodate cylindrical printing media 200 of different lengths, effectively preventing axial movement of the product during printing and ensuring printing accuracy and quality.

[0025] Furthermore, the axial limiting assembly 43 includes a limiting strip 431 that can slide independently and be locked onto the fixing frame 41.

[0026] The limiting strip 431 can be flexibly adjusted to accommodate cylindrical printing media 200 of different lengths. When a specific length of cylindrical printing media 200 needs to be accommodated, simply slide the limiting strip 431 to the appropriate position and lock it in place. This ensures that the cylindrical printing media 200 is stably placed on the drive roller 42, preventing axial movement and thus guaranteeing the stability and printing quality of the cylindrical printing process. The operation is simple and convenient, greatly improving the ease of use and applicability of the equipment.

[0027] Furthermore, the fixed frame 41 is provided with a guide structure extending along the axial direction of the drive roller 42, and locking elements are provided on both sides of the limiting strip 431. The limiting strip 431 cooperates with the guide structure through the locking elements to achieve its sliding and locking on the fixed frame 41.

[0028] The guiding structure guides the sliding of the limiting strip 431 to ensure that it moves stably along the axial direction of the drive roller 42 without deviation or wobbling. The locking element securely locks the limiting strip 431 to the fixing frame 41 when it slides to a suitable position adapted to the length of the cylindrical printing medium 200, preventing displacement due to vibration or other factors during printing. The cooperation between the guiding mechanism and the locking element makes the adjustment of the limiting strip 431 more precise and reliable, further improving the printing equipment's adaptability to cylindrical printing media 200 of different lengths and the stability of printing.

[0029] Furthermore, the guide structure is a groove 411 formed on the fixed frame 41, or a guide rod fixed on the fixed frame 41.

[0030] In this embodiment, the guiding mechanism is a chute 411, which is arranged along the length of the drive roller 42. In other embodiments, the guiding structure may also be a guide rod or other structures, which are not limited here.

[0031] When the guide structure adopts the form of a groove 411, its processing technology is relatively simple and the cost is low. At the same time, the depth and width of the groove 411 can be designed according to actual needs to ensure the stability and reliability of the limit strip 431 during the sliding process.

[0032] In some specific embodiments, the locking element is a locking screw. The end of the limiting strip 431 is provided with a locking hole 4311. The locking screw passes through the locking hole 4311 and extends into the slide groove 411. By rotating the locking screw, the locking screw is fixed in the slide groove 411, thereby firmly fixing the limiting strip 431 in a specific position in the slide groove 411. This is convenient to operate and can provide reliable locking force, ensuring that the limiting strip 431 will not be displaced due to vibration or external force during the printing process.

[0033] Furthermore, the middle part of the limiting strip 431 is raised relative to its two ends.

[0034] When printing on the cylindrical printing medium 200, the protrusion of the limiting strip 431 limits the cylindrical printing medium 200, thereby achieving stable limiting of the cylindrical printing medium 200. At the same time, the protrusion of the limiting strip 431 makes it easier for the operator to drive the limiting strip 431 to move.

[0035] Furthermore, the cylindrical printing module 40 also includes a drive motor 45 and a synchronous transmission mechanism 46. The drive motor 45 drives the drive roller 42 to rotate synchronously through the synchronous transmission mechanism 46. The synchronous transmission mechanism 46 is a combination of a synchronous belt 463 and a gear set, or a pure gear set transmission structure.

[0036] In this embodiment, there are two drive rollers 42. The drive motor 45 drives the two drive rollers 42 to rotate synchronously through the synchronous transmission mechanism 46, thereby causing the cylindrical printing medium 200 placed on the drive rollers 42 to rotate, and thus enabling the print head assembly 30 to complete the printing of the cylindrical printing medium 200. In this embodiment, the synchronous transmission mechanism 46 is a combination of a synchronous belt 463 and a gear set. In other embodiments, the synchronous transmission mechanism 46 can also be a pure gear transmission structure.

[0037] In some specific embodiments, the combination of the timing belt 463 and the gear set includes two first gears 461 rotatably connected to the side wall of the fixed frame 41, a second gear 462 rotatably disposed below the first gears 461, and a timing belt 463 wrapped around the outside of the two first gears 461 and the second gear 462. The two first gears 461 are respectively fixedly connected to two drive rollers 42. The output shaft of the drive motor 45 is fixedly connected to the second gear 462. During operation, the drive motor 45 drives the second gear 462 to rotate, thereby driving the timing belt 463 to rotate, and thus driving the two first gears 461 to rotate synchronously.

[0038] Furthermore, the printing device also includes a cover 50 for closing or opening the receiving slot 221; When the receiving slot 221 is closed by the cover 50, the areas of the cover 50, the first platform 21 and the second platform 22 where the receiving slot 221 is not opened cooperate to form a continuous plane for carrying the flatbed printing medium. When the receiving slot 221 is opened, the drive roller 42 of the cylindrical printing module 40 carries and drives the cylindrical printing medium 200 to rotate.

[0039] Understandably, the cover 50 allows the printing device provided in this application to freely switch between cylindrical and flatbed printing. This flexible switching method greatly enhances the applicability and practicality of the printing device, meeting the diverse printing needs of users in different scenarios. Whether printing cylindrical packaging or bottles, or flat posters and flyers, this device can handle it easily, providing users with a more convenient and efficient printing solution.

[0040] Furthermore, the cover 50 is a cover plate 51 that can be opened and closed on the receiving groove 221. The outer periphery of the groove opening of the receiving groove 221 is provided with a supporting flange 222. The cover plate 51 covers the supporting flange 222, and when the cover plate 51 covers the supporting flange 222, the top surface of the cover plate 51 is flush with the top surface of the first platform 21.

[0041] The cover plate 51 and the supporting flange 222 are fixedly connected by screws and other fasteners. When it is necessary to open the cover plate 51, simply loosen the screws and other fasteners and remove the cover plate 51 from the supporting flange 222. After completing the corresponding operation, accurately place the cover plate 51 on the supporting flange 222 and tighten the screws and other fasteners to make the cover plate 51 securely closed, ensuring that the cover plate 51 will not loosen during the operation of the equipment, thus ensuring the overall stability and safety of the equipment. At the same time, the design of the top surface of the cover plate 51 being flush with the top surface of the first platform 21 not only makes the appearance of the equipment cleaner and more beautiful, but also avoids the impact of the flatbed printing equipment on the printing equipment due to the protrusion or depression of the cover plate 51, improving the convenience and practicality of the printing equipment in actual application.

[0042] In addition, the body 10 is provided with a placement groove 11 for placing the cover plate 51. When the cover plate 51 is removed from the support protrusion 222, it is placed in the placement groove 11 to store the cover plate 51 and prevent the cover plate 51 from being lost.

[0043] Furthermore, the printhead assembly 30 includes a crossbeam 31 that can slide relative to the body 10 along the X-axis direction, a slide seat 32 that is slidably disposed on the crossbeam 31 and slides relative to the crossbeam 31 along the Y-axis direction, and a print carriage 33 that can be raised and lowered on the slide seat 32 and can be vertically raised and lowered relative to the slide seat 32 along the Z-axis direction. The print carriage 33 is provided with a printhead.

[0044] In this embodiment, the X-axis direction is the length direction of the machine body 10, the Y-axis direction is the width direction of the machine body 10 (i.e., the axial length direction of the drive roller 42), and the Z-axis direction is the height direction of the machine body 10. Since the drive beam 31 moves along the X-axis direction, the drive slide block 32 slides along the Y-axis direction, and the drive structure for driving the printing carriage 33 to move vertically up and down along the Z-axis direction are all conventional techniques in the art and do not represent any improvement in this application, these drive structures will not be described in detail in this embodiment. In practical applications, through the synergistic effect of these drive structures, the printhead assembly 30 can move flexibly within the three-dimensional space of the machine body 10, thereby achieving precise printing of flatbed and cylindrical printing media 200.

[0045] Working Principle: First, the appropriate printing mode is selected based on the type of printing medium, i.e., flatbed printing medium or cylindrical printing medium 200. When the flatbed printing mode is selected, the receiving slot 221 is closed by the cover 50 (cover plate 51). At this time, the cover 50, the area of ​​the first table 21 and the area of ​​the second table 22 where the receiving slot 221 is not opened together form a continuous and flat bearing plane. The operator places the flatbed printing medium stably on this bearing plane. Subsequently, the printhead assembly 30 starts to work. The crossbeam 31 moves along the X-axis direction under the drive of the drive structure, the sliding seat 32 slides along the Y-axis direction on the crossbeam 31, and at the same time, the printing carriage 33 is vertically adjusted along the Z-axis direction on the sliding seat 32. The print head 34 moves to the appropriate position to accurately print on the flatbed printing medium.

[0046] When the cylindrical printing mode is selected, first loosen the screws and other fasteners, remove the cover plate 51 from the support flange 222, and place it in the placement slot 11 on the machine body 10 for storage. At this time, the receiving slot 221 is open, and the drive roller 42 of the cylindrical printing module 40 is exposed. The operator places the cylindrical printing medium 200 on the drive roller 42, and adjusts the spacing between adjacent axial limiting components 43 according to the length of the cylindrical printing medium 200 through multiple sets of axial limiting components 43 that are slidably set on the fixed frame 41, and locks the axial limiting components 43 in different positions on the fixed frame 41, thereby forming multiple independent cylindrical printing stations 44 in the axial direction of the drive roller 42, ensuring that the cylindrical printing medium 200 is stably placed and preventing axial movement of the product during printing. Then, the drive motor 45 drives the two drive rollers 42 to rotate synchronously through the synchronous transmission mechanism 46, driving the cylindrical printing medium 200 to rotate. At the same time, the printhead assembly 30 moves above the receiving slot 221, so that the printhead 34 can perform comprehensive and precise printing on the rotating cylindrical printing medium 200, realizing the synchronous printing of multiple cylindrical printing media 200, which greatly improves production efficiency and ensures printing accuracy and printing quality.

[0047] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
