Description

Technical Field

[0001] This utility model relates to the field of inkjet printer technology, specifically to a dual-printer switching component for an inkjet printer. Background Technology

[0002] In industrial automated production, inkjet printers are the core components of marking equipment. The flexibility and applicability of their printhead assemblies directly affect production efficiency and marking quality. Existing inkjet printer printhead switching assemblies generally suffer from the following technical bottlenecks.

[0003] Angle adjustment is limited. Traditional printhead brackets are mostly fixed structures, allowing only limited angle adjustment via manual knobs or screws, and require tools for operation. This makes it difficult to quickly adapt to complex coding scenarios such as curved and inclined surfaces. Furthermore, the multi-printhead coordination capability is insufficient. Existing dual-printhead structures mostly use a translation switching method, with fixed printhead spacing and no independent height adjustment, making it difficult to meet the needs of multi-printhead combination printing. Stability and ease of operation are contradictory. Some devices improve stability by adding limiting structures, but this requires frequent disassembly and adjustment of parts, resulting in low operating efficiency. Modular design is lacking. Existing multi-printhead systems are mostly integral structures with a fixed number and arrangement of printheads, making it impossible to dynamically combine and disassemble them according to the coding content. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a dual-nozzle switching component for inkjet printers, which solves the problems in the prior art: multi-angle stepless adjustment of the printhead is achieved through the sliding cooperation of the guide rod and the positioning block; the nested structure of the support rod and the positioning sleeve supports independent adjustment of the height and angle of multiple printheads; and the anti-loosening design, such as the anti-slip sleeve and the limiting rod, ensures stable positioning after adjustment. This component allows for rapid adjustment of angle and height without tools and supports modular assembly and disassembly of the printheads, significantly improving the adaptability of the inkjet printer to workpieces of different shapes and materials.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figures 1 to 4 This utility model embodiment provides a coding machine applicable to scenarios requiring rapid switching between different coding needs at multiple workstations. This embodiment improves the structure of the coding machine to enable rapid switching between multiple coding nozzles. Specifically, taking coding requirements at different positions and angles as an example, as a preferred solution in this embodiment, the coding machine is a dual-printer switching component, capable of rapid switching and installation positioning between multiple coding machines.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a dual printhead switching component for an inkjet printer, which is mainly used in scenarios requiring rapid switching between different printing needs at multiple workstations.

[0024] The device includes a fixing clip 1, a guide rod 4 fixedly connected to the outer surface of the fixing clip 1, an anti-slip sleeve 5 sleeved on the outer surface of the guide rod 4, a positioning block 6 sleeved on the outer surface of the guide rod 4, a support base 8 slidably connected to the outer surface of the positioning block 6, a support rod 11 fixedly connected to the top of the support base 8, a positioning sleeve 12 slidably connected to the outer surface of the support rod 11, a locking block 14 fixedly connected to the other side of the outer surface of the positioning sleeve 12, a support frame 15 snapped onto the outer surface of the locking block 14, and an inkjet printer 16 fixedly installed on the outer surface of the support frame 15.

[0025] In this embodiment, the fixing clip 1 is the foundation of the entire assembly. Its main function is to securely install the dual-printhead switching assembly on the main frame of the inkjet printer, ensuring the stability of the assembly during operation and preventing shaking, thus providing a strong guarantee for the accuracy of the inkjet printing. The guide rod 4 provides a sliding and rotating path for the positioning block 6, allowing the positioning block 6 to move and rotate flexibly on its surface. The anti-slip sleeve 5 mainly increases the friction force. When the positioning block 6 is adjusted to the appropriate position, it can prevent the positioning block 6 from sliding on its own, ensuring the stability after angle adjustment. The support rod 11 provides a vertical sliding track for the positioning sleeve 12. The positioning sleeve 12 can slide up and down on its surface, thereby adjusting the height of the inkjet printer 16. The locking block 14 is connected to the support frame 15 by a snap-fit ​​method. This connection method has the advantages of convenient installation and disassembly. The main function of the support frame 15 is to fix the inkjet printer 16, and it can be flexibly combined and disassembled according to the actual inkjet printing needs. As the core component that directly performs the inkjet printing operation, the inkjet printer 16 is responsible for accurately printing the required information on the product surface. Through the flexible adjustment of its angle and height by the preceding structures, the inkjet printer 16 can adapt to the inkjet printing needs of workpieces with different shapes and materials, improving the quality and efficiency of inkjet printing.

[0026] In the above embodiment, as a preferred solution, the bottom of the fixing clamp 1 is threaded with an adjusting rod 2, and the top of the adjusting rod 2 is rotatably connected to a pressure plate 3. When the adjusting rod 2 is rotated, the pressure plate 3 can be driven to move up and down. In this way, clamping operations can be performed on installation parts of different sizes, greatly enhancing the versatility of the component and enabling it to adapt to a variety of different installation environments.

[0027] In the above embodiment, as a preferred solution, guide grooves 7 are provided on both sides of the outer surface of the positioning block 6. The inner wall of the support base 8 is slidably connected to the inner wall of the guide groove 7. The positioning block 6 serves as the key hub connecting the guide rod 4 and the support base 8. It can slide and rotate along the guide rod 4, thereby adjusting the angle of the inkjet printer 16. The guide groove 7 provides precise guidance for the sliding of the support base 8 and limits the sliding range of the support base 8, ensuring the stability and accuracy of the sliding process.

[0028] In the above embodiment, as a preferred solution, the outer surface of the support base 8 is threaded with a limiting rod 9, and the inner walls of the two guide grooves 7 are provided with limiting grooves 10. The support base 8 is mainly used to support the upper inkjet printer 16 structure and can slide freely in the guide grooves 7. When the limiting rod 9 is tightened, its end will press tightly against the anti-slip sleeve 5. This not only fixes the position of the support base 8, but also increases the friction and prevents the support base 8 from sliding.

[0029] In the above embodiments, as a preferred option, one end of the limiting rod 9 that penetrates into the support base 8 is inserted into the inner wall of the limiting groove 10, and the other end of the limiting rod 9 that penetrates into the limiting groove 10 abuts against the outer wall of the anti-slip sleeve 5.

[0030] In the above embodiment, as a preferred solution, a pressure rod 13 is threaded through one side of the outer surface of the positioning sleeve 12. One end of the pressure rod 13 is inserted into the positioning sleeve 12 and abuts against the outer wall of the support rod 11. The positioning sleeve 12 is used to install the locking block 14 and can slide and rotate along the support rod 11 to further adjust the height and angle of the inkjet printer 16. When the pressure rod 13 is tightened, its end will press tightly against the support rod 11. By increasing the friction, the position of the positioning sleeve 12 can be fixed to ensure that the inkjet printer 16 is highly stable during operation.

[0031] In this invention, the working steps of the device are as follows:

[0032] First, insert the fixing clip 1 into the installation position of the main frame of the inkjet printer, rotate the adjusting rod 2 to drive the pressure plate 3 to rise until it clamps the installation position, ensuring that the components are stable.

[0033] Next, loosen the limiting rod 9 so that the positioning block 6 can slide or rotate along the guide rod 4. Adjust the positioning block 6 to a suitable angle according to the coding requirements, tighten the limiting rod 9 so that its end passes through the support seat 8 and abuts against the anti-slip sleeve 5 to ensure that the positioning block 6 is fixed.

[0034] Then, loosen the pressure rod 13 so that the positioning sleeve 12 can slide up and down along the support rod 11. Adjust the positioning sleeve 12 to the target height, tighten the pressure rod 13 so that its end presses against the support rod 11, fix the position of the positioning sleeve 12, install a single printhead, and attach the inkjet printer 16 to the card block 14 through the support frame 15 to ensure a firm connection. Combine the printhead arrangement according to the inkjet content requirements.

[0035] Finally, clean the nozzle of the inkjet printer 16 regularly to prevent clogging from affecting the printing quality. Loosen the locking block 14 and the support frame 15, and quickly replace the printhead. After replacement, repeat steps four and five to ensure that the new printhead works properly.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
