Description

Technical Field

[0001] This utility model relates to the field of inkjet printer technology, specifically to a positioning device for the printhead of an inkjet printer inspection machine. Background Technology

[0002] In modern industrial production, inkjet printing quality inspection machines are widely used in product packaging, food, pharmaceuticals and other fields to print information such as production date, batch number and expiration date on products to meet the needs of quality traceability and anti-counterfeiting. However, the positioning device of the printhead of the existing inkjet printing quality inspection machine has many problems and is difficult to meet the needs of efficient and accurate production.

[0003] On the one hand, the positioning accuracy and stability of the printhead are insufficient. Traditional positioning devices are mostly fixed structures. Once installed, the position and angle of the printhead are difficult to adjust, making it impossible to adapt to changes in different product specifications and production needs. In actual production, equipment vibration, environmental interference, and wear of mechanical parts due to long-term use can all cause the printhead to shift, thereby affecting the accuracy and quality of the coding. It may even lead to incorrect coding position, unclear characters, or detection failure, seriously affecting the appearance quality and pass rate of the product and increasing the production cost of the enterprise.

[0004] On the other hand, the installation and disassembly of the nozzles is cumbersome. Existing nozzle installation methods often require the use of multiple tools and involve complicated operating procedures. This not only increases the time cost of equipment maintenance and debugging, but also reduces production efficiency to some extent. This inconvenience is particularly prominent when frequent nozzle replacement or equipment maintenance is required, leading to extended equipment downtime and affecting the company's production capacity and economic benefits.

[0005] In addition, existing positioning devices lack versatility and flexibility, making it difficult to adapt to various nozzle specifications and diverse production scenarios. This often requires companies to redesign or replace the entire positioning device when facing different product or process requirements, increasing equipment investment costs and management complexity.

[0006] In view of the above-mentioned shortcomings of the existing inkjet printer nozzle positioning device, there is an urgent need for an improved device that can achieve accurate, flexible and stable positioning and is easy to install and disassemble, so as to improve the performance and reliability of inkjet printers and meet the high-efficiency and high-quality requirements of modern industrial production.

The positioning shaft 4 is fixedly mounted to the fixing clamp 1, and its outer wall is rotatably connected to the support rod 5. This design gives the support rod 5 a certain degree of mobility, allowing the printhead to be adjusted in angle according to different needs, improving the flexibility and applicability of the device. The guide groove 7 on the outer surface of the support rod 5 provides support... The movement of the support seat 8 provides a guiding path, ensuring that the support seat 8 can move smoothly and accurately along the support rod 5. Simultaneously, the structure of the support rod 5 sleeved onto the support seat 8 further enhances its supporting effect. The pressure rod 6, threaded below the outer surface of the support rod 5, penetrates the support rod 5 and abuts against the outer wall of the positioning shaft 4, effectively preventing unnecessary rotation or displacement of the support rod 5 on the positioning shaft 4, ensuring the stability of the adjusted nozzle position. The guide groove 7, formed on the outer surface of the support rod 5, provides guidance for the movement of the support seat 8, enabling it to move smoothly and accurately along a predetermined path, preventing offset or shaking during movement, thus ensuring the spray nozzle's position. To ensure accurate nozzle positioning, the support base 8 is fitted onto the outer surface of the support rod 5 and can move along the support rod 5. Furthermore, a positioning seat 10 is rotatably mounted on its outer wall. This allows for both horizontal adjustment of the nozzle position and flexible angle adjustment, greatly improving the versatility and flexibility of the device. A fixing rod 9, threaded through one side of the outer surface of the support base 8, inserts into the support base 8 and presses against the outer wall of the support rod 5, fixing the support base 8 in a specific position on the support rod 5 to prevent displacement during operation and ensure nozzle position stability. The positioning seat 10 is rotatably mounted on the outer wall of the support base 8, further increasing the flexibility of nozzle angle adjustment and meeting the needs of different printing angles. The positioning bolt 12, inserted into one side of its outer surface, passes through the mounting base 11 and is threadedly connected to the limiting ring 13. By adjusting the positioning bolt 12 and the limiting ring 13, the mounting base 11 can be fixed at a specific angle in the positioning base 10 to ensure the angular stability of the printhead during operation. The mounting base 11 is fixedly installed on the top of the positioning base 10 and is used to install the inkjet printer printhead. The protective shell 14 inserted into its inner wall can protect the inkjet printer body 15 and prevent external factors from damaging the inkjet printer body 15.
