Rotary traction device of film blowing machine
Technical Field
The utility model relates to a wrapping bag blown film production technical field, in particular to inflation film manufacturing machine's rotatory draw gear.
Background
Inflation film manufacturing machine melts the plastic pellet heating and blows into the bubble film again, and the cylindric bubble film that blows forms the wrapping bag after cooling, hem, printing, plastic envelope, die-cut, wherein, because the cylindric bubble of extruding from the blowing machine die head is thin the thickness in every point position is inhomogeneous, and produces the deviation on the thickness, and it is even to guarantee the film book thickness after the rolling through rotatory draw gear, improves the rolling quality, like chinese utility model patent CN201320366814.8, a inflation film manufacturing machine's of disclosing rotatory draw gear, this the utility model discloses it is small, can effectively avoid the film fold moreover, improve the rolling quality. But the utility model discloses a hoist and mount are in inflation film manufacturing machine aircraft nose top, and the stationarity when the actual operation is relatively poor.
