Rotary Servo Screen Printer: Digital Control And High Reliability Printing Solution

As an important equipment in the modern printing industry, the rotary servo screen printer integrates digital control technology, precision servo drive system and high-quality pneumatic components, providing efficient and accurate solutions for various flat and curved surface printing needs. This article will comprehensively introduce the technical characteristics, system structure, performance advantages and application scenarios of the rotary servo screen printer, and show how this equipment can achieve the perfect combination of ease of operation and operational reliability through technological innovation.

Equipment overview and technical features

The rotary servo screen printer represents the current high-end technology level in the field of screen printing. Its core design concept is to solve the limitations of traditional printing equipment in terms of efficiency, accuracy and stability through the integration of digital control and precision machinery. This type of equipment usually adopts a multi-station rotating platform design, of which Henghui SR-130F5 is a typical representative. It is equipped with a five-station rotating worktable to achieve synchronous operation. Each station is responsible for workpiece placement, printing, dual-station drying and pick-up functions. It is driven by a stepper motor or servo motor to ensure smooth and smooth operation.

In terms of control systems, modern rotary servo screen printers generally adopt advanced digital computer control, such as a combination of PLC (programmable logic controller) and human-machine interface (HMI). High-performance control systems represented by Mitsubishi PLC can achieve precise management of the printing process and self-diagnosis of faults. When an error occurs in settings or operations, the equipment will immediately stop and the fault point will be clearly displayed on the human-machine interface to facilitate quick troubleshooting. The human-machine interface usually supports bilingual display in Chinese and English. Digital control can quickly select and set multiple printing modes, and flexibly adjust parameters according to different printing requirements, significantly improving operational convenience and production efficiency.

The pneumatic system is the key to ensuring the accurate execution of printing movements. High-end rotary servo screen printers generally use imported brand pneumatic components, such as SMC, Festo, etc. These components have the characteristics of fast response, long service life, and high stability. The pneumatic system is mainly responsible for controlling key processes such as the movements of the scraper and return knife, as well as the lifting and lowering of the screen. Its performance directly affects the stability of the printing quality and the reliability of the equipment operation. Imported pneumatic components combined with precise pressure adjustment devices ensure balanced and consistent printing pressure, maintaining stable printing quality even in long-term continuous operations.

Servo drive technology is another core technical advantage of rotary servo screen printers. Compared with traditional mechanical transmission methods, the servo system reduces unnecessary energy consumption and improves overall energy efficiency by accurately controlling the movement of the motor. The servo motor has the characteristics of high torque response, precise positioning and rapid acceleration and deceleration, and can meet the strict requirements of position accuracy and synchronization of the screen printing process. For example, in the Hexin A4 servo-driven four-axis linkage screen printing machine, the servo system accurately coordinates the movements of multiple axes such as screen movement, scraper print head movement, and lifting movement, ensuring that even complex items with rectangular or rounded rectangular cross-sections (such as bottles, lipstick caps, etc.) can obtain high-quality printing results.
