Description

Technical Field

[0001] This utility model relates to the field of thermal transfer printing equipment technology, and in particular to direct connection of thermal transfer printing encoder. Background Technology

[0002] Thermal transfer printers are widely used in modern industrial production, office work, and personalized customization. However, the pressure roller drive structure of traditional thermal transfer printers has several shortcomings. For example, low transmission precision can easily lead to uneven paper feeding during printing, affecting print quality and causing issues such as pattern misalignment and blurring. Some transmission structures also exhibit poor stability, generating significant vibration and noise during prolonged high-speed operation, which not only reduces the equipment's lifespan but also interferes with the working environment. Furthermore, the complex transmission structure increases manufacturing costs and maintenance complexity.

[0003] Therefore, it is necessary to provide a direct connection between the thermal transfer printing encoder and the above-mentioned technical problems. Utility Model Content

A drive motor is installed inside the device body, and a main shaft roller is mounted on the output end of the drive motor via a transmission shaft. Pressure rollers are movably mounted on both sides of the main shaft roller inside the device body. A mounting frame is installed inside the device body, and a thermal transfer printer is installed inside the mounting frame. The dual pressure rollers are directly and synchronously driven by the motor main shaft, combined with a precise gear transmission structure, greatly improving transmission accuracy and ensuring smoother paper feeding during printing. This effectively avoids problems such as pattern misalignment and blurring, thus improving print quality. Simultaneously, this structure has a simple design, reducing complex transmission components and lowering manufacturing costs and maintenance difficulty. The stable transmission structure generates less vibration and noise during long-term high-speed operation, extending the equipment's service life and improving the working environment.

[0012] Compared to existing technologies, thermal transfer printing utilizes a direct-drive encoder, synchronously driving dual pressure rollers via a motor spindle. Combined with a precise gear transmission structure, this significantly improves transmission accuracy, resulting in smoother paper feeding during printing and effectively preventing issues such as pattern misalignment and blurring, thus enhancing print quality.
