Abstract
The utility model discloses a longitudinal stretching machine for a polyester optical film. The longitudinal stretching machine comprises a fame, a guide-in roller, an inlet compression roller, a preheating roller, a stretching roller, a cooling roller, a primary tension roller, a two-step stretching roller, a sizing roller, a cooling roller, a secondary tension roller, a guide-out roller and an outlet compression roller. The guide-in roller is arranged in the middle of the left side of the frame; the preheating roller, the stretching roller, the cooling roller, the primary tension roller, the two-step stretching roller, the sizing roller, the cooling roller, the secondary tension roller and the guide-out roller are sequentially arranged on the upper part of the frame from left to right; the inlet compression roller is arranged on the upper part of the preheating roller; and the outlet compression roller is arranged on the upper part of the guide-out roller. Compared with the prior art, the longitudinal stretching machine has the advantages that the film is difficult to break, the production efficiency is high, the production requirement of the high-strength film can be met, the stretching ratio is improved from 3.5 liters to 4.5 liters, the stretching in the rib direction of the film is stable, and the longitudinal strength is greatly improved.
Description
Technical field
The utility model relates to a kind of wire drawing machine, is specifically related to a kind of polyester blooming longitudinal stretching machine.
Background technology
The polyester blooming generally adopts the biaxial tension technology to produce, and concrete drawing process is divided into one by one pulling method (two-step method) and while pulling method (one-step method).Pulling method is that longitudinal stretching and cross directional stretch carry out simultaneously simultaneously, because of its stretching device complex structure, so use less at present.Pulling method is the method that generally adopts at present one by one, and it is that the longitudinal stretching of film and cross directional stretch are carried out in two steps.And there are in the drawing process easily defectives such as rupture of membranes and production efficiency are low in present polyester blooming stretching-machine of the prior art.
Summary of the invention
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of polyester blooming longitudinal stretching machine is provided.
Its technical scheme is: comprise frame, guide-in roller, entrance pressure roller, preheat roll, draw roll, chill roll, jockey pulley, two step draw rolls, setting roll, cooling stick, secondary jockey pulley, outlet roller and an outlet pressure roller.Described frame left side central portion is provided with guide-in roller, upper rack is provided with preheat roll, draw roll, chill roll, jockey pulley, two step draw rolls, setting roll, cooling stick, secondary jockey pulley and an outlet roller from left to right in turn, the top of described preheat roll is provided with the entrance pressure roller, and the top of described outlet roller is provided with the outlet pressure roller.
Wherein, described preheat roll is made as 2-4 that are arranged side by side, and the entrance pressure roller is arranged on the top of a preheat roll of the leftmost side.Described draw roll is made as 2-4 that are arranged side by side.Described chill roll is made as 2-4 that are arranged side by side.Described two step draw rolls are made as 2-3 that are arranged side by side.
The utility model has the rupture of membranes of being difficult for and production efficiency advantages of higher compared with prior art, can satisfy the production requirement of high-strength film, makes draw ratio rise to 4.5 from 3.5, and film rib direction stretches stable, and longitudinal strength improves greatly.
