详细介绍
双向拉伸薄膜生产线
Biaxially oriented film production line
特点：设备采用单螺杆（双螺杆）挤出机，并配有计量泵闭环控制，将出来的片材经过三辊进行致密压光，之后进入纵向拉伸机进行多倍数纵向拉伸，拉伸完冷却定型，在经过横向多倍数拉伸定型，设备采用红外线感应探头进行时时在线纠偏，保证设备拉伸稳定出来的产品厚度稳定，收卷采用间隙收卷（摩擦收卷）方式，恒张力控制，生产加减速度可以同步比率控制，速度可以达到50mmin_100mmin
Characteristics: The equipment adopts single-screw (double-screw) extruder and is equipped with closed-loop control of metering pump. The sheet is compacted and calendered through three rollers.Longitudinal stretching machine performs multiple-fold longitudinal stretching, stretching and cooling setting, and adopting infrared multi-intensity stretching and setting, the equipment is always used in the infrared induction probe.Correction, to ensure the stability of the product is stable, the winding is closed by the winding (friction winding), constant tension control, production acceleration and deceleration can be the sameStep ratio control, the speed can reach 50mmin_100mmin
工艺原理：将塑料颗粒投入到挤出机熔融塑化→快速过滤网→计量泵→衣架式模具→ 压延定型 →纵向拉伸机 →冷却定型装置 →牵引装置 →横向拉伸机→分切装置 →牵引装置 →收卷装置
Process principle: Put plastic pellets into the extruder for melt plasticization→rapid filter→metering pump→hanger mold→calender shaping→longitudinal stretching machine →Cooling and setting device → traction device → transverse stretching machine → slitting device → traction device → winding device
产品用途：主要用于包装，印刷，电子包装膜Product use: mainly used for packaging, printing, electronic packaging film
