The gearless sleeve type flexo printing machine produced by WENZHOU LISHENG PRINTING AND PACKAGING MACHINERY CO., LTD features an advanced sleeve system design, significantly enhancing printing efficiency and quality. The sleeve system, as one of the core components of the printing machine, primarily supports the printing cylinder, ensuring precise registration and efficient replacement processes.

The printing roller adopts an inverted inline cantilever end locking support structure, combined with double-line precision roller bearings and an air expansion mandrel, ensuring convenient and quick sleeve replacement. This design allows operators to quickly change sleeves at any position without complex adjustments, significantly reducing printing preparation time and enhancing production efficiency.

The sleeve disassembly and installation process is also straightforward. Thanks to the tight fit between the sleeve and the mandrel, operators can easily replace the sleeve by inflating it at any position where the mandrel stops. This convenient operation is suitable for various printing tasks, especially for printing businesses that require frequent plate changes.

Advantages of the Sleeve Application
The sleeve system in the gearless sleeve type flexo printing machine not only offers efficient replacement speed but also provides high precision and stability. With a gearless full servo drive system, the rotational accuracy of the sleeve is greatly improved, ensuring that the printing registration accuracy is within ±0.08mm during the printing process.

Moreover, the sleeve design fully considers material compatibility and diversity, supporting replacements with different printing lengths from 500mm to 900mm. Customers can choose the appropriate sleeve length according to their printing needs to achieve diversified production. Whether it is for short-run jobs or long-run printing, the sleeve system can provide stable performance.

 Impact of the Sleeve System on Printing Quality
The high-precision sleeve system provides better printing quality assurance for the printing machine. With fully automatic alignment and pressure adjustment functions, the sleeve system can automatically compensate for changes in printing pressure during acceleration or deceleration, avoiding instability in printing quality due to speed changes. The printing pressure can be automatically adjusted according to speed to ensure optimal printing results each time.

In summary, the gearless sleeve type flexo printing machine by WENZHOU LISHENG PRINTING AND PACKAGING MACHINERY CO., LTD, with its excellent sleeve system design, can provide customers with efficient and precise printing solutions, making it an ideal choice for the packaging printing industry.
