Description
Technical Field
[0001] This utility model relates to the field of digital printer technology, specifically a convertible scanning printer with a printhead adjustment structure. Background Technology
[0002] With the increasing demand for personalized and high-precision printing in various industries, such as advertising production, packaging printing, and industrial signage, printers not only need to complete printing tasks quickly and efficiently, but also need to have flexible printhead adjustment functions to adapt to different printing modes and media.
[0003] On the production line, there are often situations where it is necessary to switch between scanning printing and single-pass printing. Scanning printing is suitable for scenarios with high precision requirements and complex patterns but where printing speed is not critical. Single-pass printing, on the other hand, can meet the needs of high-speed, high-volume printing. Traditional printers often have fixed printhead positions, which cannot meet this flexible switching requirement. As a result, when facing different production tasks, it is necessary to purchase multiple printers of different types, which increases equipment costs and space requirements.
[0004] Furthermore, precise printhead adjustment is crucial for ensuring print quality. During the printing process, even slight changes in parameters such as the distance and angle between the printhead and the printing medium can lead to issues such as deviations in the printed pattern, uneven color, or decreased resolution. Some existing printhead adjustment devices either lack sufficient adjustment precision or have complex structures, poor reliability, and are difficult to maintain and operate, thus affecting the overall performance and efficiency of the printer. Therefore, a convertible scanning printer with a printhead adjustment structure is proposed. Utility Model Content

At this time, the inkjet assembly is in a horizontal position, the limit block is inserted into the slot, and the locking hole corresponds to the limit hole. The positioning pin can be inserted into the locking hole and the limit hole to lock the inkjet assembly.
[0011] Preferably, the frame and the back plate are rotatably connected by a hinge, and when the handle of the frame faces directly forward, the limiting hole corresponds to the insertion hole.
[0012] With the above technical solution, a top plate is set up. When the printer body is in scanning and printing mode, the inkjet assembly is in a vertical position with the handle facing forward. The limiting hole and the insertion hole correspond to each other. The positioning pin can be inserted into the insertion hole and the limiting hole to lock the inkjet assembly.

[0018] With the above technical solution, both the right end of worm one and the front end of worm two are provided with external hexagonal connecting handles, which facilitates manual operation of worm one and worm two using external tools. For example, in the event of motor failure or the need for fine adjustment, the worm can be rotated using tools such as wrenches through the external hexagonal connecting handles to manually adjust the angle of the rotary seat assembly, thereby increasing the convenience of equipment maintenance and debugging and improving the operability and adaptability of the equipment.
[0019] Preferably, the slide groove and the slide bar are slidably connected, and the inkjet assembly and the frame are locked together by bolts.
[0020] Through the above technical solution, the sliding connection between the slide groove and the slide bar allows the inkjet assembly to slide smoothly within the frame, realizing the position adjustment of the inkjet assembly in one direction. Combined with the bolt locking connection with the frame, the inkjet assembly can be firmly fixed after being adjusted to the appropriate position, ensuring the stability of the inkjet assembly during printing and improving print quality. At the same time, this connection method facilitates the installation and disassembly of the inkjet assembly, making it convenient for maintenance and replacement of the inkjet assembly.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Example 1: As Figure 1-5 As shown, the present invention provides a convertible scanning printer with a printhead adjustment structure, including a printer body 1 and a translation guide rail 2 disposed on the upper end of the printer body 1, and a fixed base assembly 3 at the front end of the translation guide rail 2.

[0036] Example 2: Figure 2-5 As shown, this is an improvement on the previous embodiment.
[0037] Specifically, the worm gear 406 and the worm wheel 404 are meshed together. The advantage is that when the motor 407 drives the worm gear 406 to rotate, it can accurately and stably drive the worm wheel 404 to rotate, thereby achieving precise angle adjustment of the swivel base 409 and the connecting components.
[0038] Specifically, worm gear 413 and worm wheel 411 are meshed together. The advantage is that when motor 414 drives worm gear 413 to rotate, it can stably drive worm wheel 411 to rotate, enabling angle adjustment of the rotary table 415 and connected components. Combined with the meshing transmission of worm gear 406 and worm wheel 404, this allows for precise control of the inkjet assembly 5's position in multiple dimensions. This transmission method ensures the accuracy and reliability of angle adjustment and improves the flexibility of printer head adjustment.
[0039] Specifically, both the right end of worm gear 1 (406) and the front end of worm gear 2 (413) are equipped with external hexagonal connecting handles. The advantage is that these handles facilitate manual operation of worm gears 406 and 413 using external tools. For example, in case of motor failure or fine-tuning, the worms can be rotated using tools such as wrenches via the hexagonal connecting handles to manually adjust the angle of the rotary seat assembly.

[0041] Working principle: When in use, with the printer body 1 in scan printing mode, the inkjet assembly 5 is in a vertical position, the handle 418 faces forward, and the limiting hole 403 corresponds to the insertion hole 306. The positioning pin can be inserted into the insertion hole 306 and the limiting hole 403 to lock the inkjet assembly 5. A slot 302 and a limiting block 402 are provided. When the printer body 1 needs to switch to single mode... In pass printing mode, hold handle 418 and move it to the right, causing back plate 401 to rotate relative to frame 304 until handle 418 faces right. At this time, inkjet assembly 5 is in a horizontal position, limit block 402 is inserted into slot 302, and locking hole 303 corresponds to limit hole 403. Positioning pin can be inserted into locking hole 303 and limit hole 403 to lock inkjet assembly 5. The operation is simple and the structure is ingenious.
