Small precision film longitudinal stretching machine

Product Introduction 
Small precision film longitudinal stretching machine can conduct continuous longitudinal stretching tests on film samples of a certain size at the required stretching ratio at a suitable temperature, and can obtain high-performance longitudinally stretched film products for researchers to analyze.
 
Small precision film longitudinal stretching machine consists of unwinding assembly, preheating roller group, stretching roller group, annealing roller group, cooling roller group,traction assembly, winding assembly, edge trimming assembly and electronic control system. This machine is a vertical structure with a small area.
DESCRIPTION
Key Features
● Wide process range, can achieve near "zero distance" stretching.
● Innovative structural design realizes the overall movement of the stretching roller assembly.
● Based on the fully digital servo position semi-closed loop control, precise adjustment of roller position and stretching spacing can be achieved.
● Fully digital network control technology realizes synchronous control of multiple rollers and precise control of stretching speed ratio.
● Interactive human-machine interface design based on touch screen to achieve centralized control.
● Individual/synchronous control of each roller can be achieved by selecting the roller connection status, which is easy to operate.
● Modular design, easy to integrate with different experimental lines to meet the user's individual needs.
