雙向拉伸薄膜生產線
Biaxially oriented film production line
特點：設備采用單螺桿（雙螺桿）擠出機，并配有計量泵閉環(huán)控制，將出來的片材經過三輥進行致密壓光，之后進入縱向拉伸機進行多倍數縱向拉伸，拉伸完冷卻定型，在經過橫向多倍數拉伸定型，設備采用紅外線感應探頭進行時時在線糾偏，保證設備拉伸穩(wěn)定出來的產品厚度穩(wěn)定，收卷采用間隙收卷（摩擦收卷）方式，恒張力控制，生產加減速度可以同步比率控制，速度可以達到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
工藝原理：將塑料顆粒投入到擠出機熔融塑化→快速過濾網→計量泵→衣架式模具→ 壓延定型 →縱向拉伸機 →冷卻定型裝置 →牽引裝置 →橫向拉伸機→分切裝置 →牽引裝置 →收卷裝置
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
產品用途：主要用于包裝，印刷，電子包裝膜Product use: mainly used for packaging, printing, electronic packaging film
