Description
Technical field
The utility model belongs to the technical field of plastic sheeting manufacturing equipment, is specifically related to a kind of plastic film blowing method production line.
Background technology
Plastic sheeting can adopt blowing to produce, during production, molten plastic material is extruded from the annular die gap of die head and forms the film bubble of annular, also be blown into pressed gas toward film bubble inside simultaneously, make bubble blown, inflation ratio is larger, and film bubble just becomes thinner, finally become cylindric film, then be drawn past herringbone clamping plate by traction nip rolls, cylindric plastic sheeting is just collapsed into as eighty percent discount, afterwards just can rolling.Film volume width after rolling is not preferably exceeding about 2.0 meters, if the amplitude of plastic sheeting is wider, then also needs before rolling to be carried out by plastic sheeting being further converted into four fold or eight foldings, so that further reduced width, and then is convenient to carrying, storage.
But because plastic film roll extremely compacts, therefore along with increasing of number of times amounted to by plastic sheeting, knuckle position will receive increasing stretching, as in FIG, plastic sheeting is converted into eight foldings, then two-layer 81, the 82 knuckle place Tensile degree inside it are little, but its two outside layers 83,84 knuckle place Tensile degree is larger, wherein outermost layer 84 knuckle place (in Fig. 1 shown in A point) will receive and stretch significantly, and this local is easily affected total quality by pulling.
For above-mentioned reasons, in prior art, plastic sheeting is difficult to be converted into eight foldings, even if there is minority to be converted into the plastic sheeting of eight foldings, also there is quality risk due to outer corner excessive tensile.Like this, when the horizontal amplitude of the film produced is very large, manufacturer is just faced with dilemma: or the problem that film volume width overlength brings must be there is, or there is film outermost layer knuckle by the quality risk pulled.
In addition, the film volume doubling number of plies of existing plastic film blowing method production line only has single selection, and each concrete production line can only select a kind of mode to carry out rolling in two foldings, four fold, eight compromises.
