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 developed by POTOP is an engineering instrument with good repeatability and precise control. It can be operated offline and is equivalent to a production line. It can improve experimental efficiency and shorten product development cycle.
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.
● 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.
Industries: Modified plastics, functional films, packaging materials, biodegradable materials, and specialty engineering plastics
