HN-SF106 Full Servo Control Stop Cylinder Screen Printing Machine
HN-SF106 Full Servo Control Stop Cylinder Screen Printing Machine
Introduction
●The HN-SF series servo fully automatic screen printing machine is a new intelligent screen printing machine independently developed and designed by our company, with complete independent intellectual property rights. It is an industry-leading product with three invention patents and five utility model patents. Full size printing can reach a speed of 4500 sheets/hour while ensuring the quality of the printed product. For personalized product printing, the speed can reach up to 5000 sheets/hour. It is the perfect choice for industries such as high-quality paper and plastic packaging, ceramic and glass paper, textile transfer, metal signage, plastic film switches, and electronic and electrical related components.
●This machine abandons the traditional mechanical transmission shaft, gearbox, chain, and crank mode, and adopts multiple servo motors to drive the paper feeding, cylinder, and screen frame separately. Through automation control, it ensures the synchronization of several functional units, not only eliminating a lot of mechanical transmission components, but also greatly improving the stiffness of printing machinery, reducing errors caused by mechanical transmission devices, and improving printing quality and mechanical efficiency, Improved the automation level of the production process and improved the working conditions of the environment.
Main Features
HN-SF106 Full Servo Control Screen Press Advantages
1. Short stroke operation of screen printing: By changing the stroke data of the printing plate, the movement stroke of the screen printing can be easily changed. For small area products, it can effectively extend the service life of the screen printing and improve the printing speed while ensuring the printing effect;
2. Large proportion of printing ink return speed ratio: There is one ink return action and one printing action in one cycle of screen printing. By setting different speed ratios, the production capacity can be increased while ensuring the printing effect; Especially for high penetration inks, a high ink return speed can effectively reduce the pattern deformation and ink shedding caused by ink penetration after ink return. A low printing speed can also improve the printing effect;
3. Significantly shifting the pattern back and forth: By modifying the starting point of the frame servo, it is possible to quickly solve the problem of missing bite size during printing, or to quickly achieve the completion of paper direction alignment through data changes during the screen register;
4. Scaling of printing patterns: By modifying the data, the 1:1 drum to frame speed ratio is slightly changed, changing the original 1:1 printing pattern to 1:0.99 or 1:1.01, etc., in order to compensate for the shrinkage deformation of the paper during process conversion and storage, as well as the pattern stretching deformation caused by insufficient screen tension;
5. Adjustment of paper feeding time: By adjusting the original point data of the Feida motor, the material conveying time is modified to quickly achieve the delivery time of special materials to the front side gauge, ensuring the stability and accuracy of paper feeding;
6. By reducing the multi-level transmission mechanism and increasing the transmission rigidity, the servo transmission system can change the speed faster, reduce the machine adjustment time, and shorten the machine speed up and down cycle, thereby greatly reducing the overprint waste caused by different screen deformations in screen printing at high and low speeds, reducing the waste rate, and improving efficiency;
7. Multiple power transmission systems, each equipped with temperature monitoring and fault display, can provide early warning in case of transmission system failure; After the transmission is independent, the fault point can be quickly located through the transmission system alarm;
8. Multi axis servo transmission and energy-saving technology are adopted for energy recovery and reuse. At the same speed, the servo model saves 40-55% energy compared to the mechanical transmission type main transmission system, and during normal printing, it saves 11-20% energy.
HN-SF106 Pneumatic Squeegee Bridge Advantage
New pneumatic squeegee system:
The traditional cylinder screen printing machine squeegee system is controlled by a cam to control the blade holder. When the equipment screen frame runs to the front and back positions, the cam controlled scraper and ink return plate have a switching action. But with the continuous machine running speed up, the defects of this system comes out. When the scraper switches, the downward movement of the scraper will cause the mesh to be impacted. If the scraper scratches the upper surface of the cylinder gripper below the mesh, it may cause mesh damaged; When the machine is running at high speed, it can also cause instability in the positioning of the paper before printing; In addition, the most serious issue is that at high speeds, the scraper up and down will be slightly shaking. Which is reflected in the instability of the printed pattern, we called it “squeegee jumping”.
In response to the above issues, we has developed a hydraulic pneumatic squeegee bridge with servo motor controled squeegee up and down system.It overcomes the technical difficulties that have plagued the screen printing industry for many years.
The Squeegee bridge system maintains synchronous motion with the cylinder and screen frame, but there is no mechanical connection between them. The squeegee bridge system adopts servo motor controling the squeegee up and down, and hydraulic control for buffering, ensuring accurate, stable, and always constant squeegee rubber pressure. The switching action is fully matched with the cylinder speed, and the printing start and end points (switching position points) are adjustable.
