SJ-55(60、65) Rotary Die Head Film Blowing Machine Set_Zhejiang Dongfeng Plastic Machinery Co., Ltd

Uses: It is suitable for blowing the plastic film as high density polyethylene(HDPE),low density polyethylene(LDPE) and linear low density polyethylene(LLDPE

Characteristics:

1、The die head can be rotated to left and right within 360 angles,it can strengthen the intensity and evenness of plastic film.

2、The screw stem and cylinder are made of 38CRMOALA high quality alloy steel after fine finishing and nitrided treatment,which has high hardness,strong resistance to corrosion,durable service.

3、The die head is plated with hard chrome,of screw mandrel type structure with even and smooth discharging, the blown plastic film has fine finishing; The blower is of labyrinth structure with even air output.The take-up unit adopts lifting type of square-frame platform structure,the height of lifting frame can be adjusted automatically according to different technological requirements.

The coiling unit adopts pressure friction rewinding or center rewinding,which is driven by torque motor,with even and smooth rewinding and easy roll changing.
