The rotating base is fixedly connected with the rotational shell, so that the swivel bearing is wrapped in rotational shell, the mould
Be additionally provided between body and the rotary body circuit board and rotation gear, the die body sequentially pass through rotation gear and circuit board and with
The rotary body connection.
Die head rotates blown film when the operation of the utility model, while driving film bubble rotation, so that the thickness point in film bubble
Ceaselessly moving in rotation avoids the thickness point accumulation of film, gives birth to be evenly distributed in film everywhere on film bubble circumference
The film planarization of output is good, and intensity is high, and since die body and rotary body have been all made of housing auxiliary protection to overcome rotation
Revolving die head is easy the defect of material leakage, and structure is simple, and easily fabricated, cost is lower.
Preferably, the rotating base is fixed by bolts with the rotational shell, is adopted between described two adjacent bolts
It is fixed with different depth, the bolt of different depth is fixed to be avoided rotating base and rotational shell from being too closely bonded damaging.
Further, the die body includes mould mouth, mould bowl and die sleeve, and the mould bowl is socketed in outside the mould mouth, the mould
Set is connect with the mould bowl, and die sleeve during ensure that membrane is also unlikely to that material leakage is caused to influence production, improves production efficiency
With quality.
Preferably, the circuit board includes at least two through-holes of different sizes, and the die body passes through the through-hole and rotation
Swivel connection, may be selected different size of through-hole according to actual needs, to realize that heating is more uniform, it is heated to avoid film bubble
Unevenness influences film quality.
Preferably, the mould mouth is infundibulate, and setting is so that film bubble flowing is more steady, with the needs of membrane in this way
Guarantee pressure change.
Preferably, the charging pedestal includes feed inlet and feeding port, and the rotating base is connect with the feeding port.
Further, the rotation gear is equipped with multiple, and rotation gear auxiliary die body rotates in process of production.
Further, it is equipped with bearing in the rotating base, supports mechanical rotary body, reduces rubbing in its motion process
Coefficient is wiped, and guarantees its rotating accuracy.
