SJ-55（40、60、70）聚丙烯旋转模头吹膜机适用于吹制聚丙烯（PP）塑料薄膜，广泛应用于食品、服装、纺织品、日用品等民用品和工业品的包装。
特点： 1、模头能360左右旋转，可增强塑料薄膜的强度和均匀度。 2、螺杆、料筒均采用38CRMOALA合金钢，经氮化处理和紧密加工而成，硬度高，耐腐蚀性强，经久耐用。 3、模头镀硬铬，其结构为螺旋芯轴式，挤出的熔料均匀，吹制的薄膜光洁度好；风冷装置结构为迷宫型，出风量均匀，采用循环水冷却，从而使吹制的薄膜达到的透明度。 4、卷取装置采用压力摩擦收卷或中心收卷，采用力矩电机调节，收卷平整，换卷方便。 Use: The machine is suitable for producing PP. it is widely be used for packing food, garment, textile, daily necessaries and industrial product etc. Characteristics:
-
- 1. Die head can be turned 360°, it can strengthen the tension and evenness degree of film.
- 2. Screw stem and cylinder are all made of 38CRMOALA alloy, and treated by nitrogen. It has an advantage of great thickness,
corrosion resistance and endurance etc. - 3. Die head has been chromized, it’s advantage of screw core structure, melting material extruding evenly, and blowing film smoothly
etc. cooling equipment is a labyrinth blow pump which has good effect. Especially, it adopts the recycling cooling water system to ensure
the best transparent effect. - 4. Discharging equipment adopts pressing braking winding equipment& central winding equipment, and it adopts torque motor to
adjust, has the merits of smooth film, convenience operation.
