PET食品级吸塑片材生产线（结晶型）

PET food grade blister sheet production line (crystalline)

特点：螺杆采用平行双螺杆设计，专门针对聚酯PET，具有排气性，塑化均匀，斜三辊压延设计以及L型压延设计，辊筒温度通过模温机可调，出来的产品韧性好，透明度高，同时设有预涂硅油装置，保证二次加工时脱模容易片材厚度采用千分表定位，收卷采用自动张力卷取。

Features: The screw adopts parallel twin-screw design, specially designed for polyester PET, with venting, uniform plasticization, oblique three-roll calender design and L-type calender design. The roller temperature can be adjusted by the mold temperature machine, and the product has good toughness. It has high transparency and pre-coated silicone oil device to ensure the release of the sheet during the secondary processing. The thickness of the sheet is positioned by the dial gauge, and the winding is automatically tensioned.

工艺原理：聚酯颗粒切片除湿干燥结晶→平行双螺杆挤出机：原料融熔塑化→ 快换过滤网→溶体泵→挤出模头成型挤出 → 斜三辊压光机 → 冷却定型装置→ 切边机构→牵引传送→ 自动张力收卷

Process principle: Dehumidifying and drying crystallization of polyester pellets→Parallel twin-screw extruder: raw material melting and plasticizing → quick change filter → solution pump → extrusion die forming extrusion → oblique three-roll calender → cooling setting device → Trimming mechanism → traction transmission → automatic tension winding
