Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment 1
As shown in Fig. 1 ~ 2, a kind of Biaxial Oriented Plastic Film Line cross directional stretch section chain folder cooling system, described cross directional stretch section comprises the preheating zone 6 being arranged on baking oven 9 inside, cross directional stretch district 7 and heat set zone 8, described baking oven 9 internal membrane both sides are respectively provided with a chain clipping system, this chain clipping system comprise for horizontal draw the chain of film press from both sides 10 and for chain folder 10 provide transfer motion power chain folder driving 11, described chain folder 10 is set in the driving 11 of chain folder, and when moving to film side with the driving 11 of chain folder, film clamped by chain folder 10, and cross directional stretch film, when chain folder 10 moves to heat set zone 8 afterbody with roller bearing 11, chain folder 10 unclamps, and turning to the opposite side cooling relative with film along the driving 11 of chain folder, described cooling system comprises blower fan 1, cooler 2, blowing mouth 3, airduct 4 and cooling water pipe 5, described blower fan 1 connects blowing mouth 3 by airduct 4, described blowing mouth 3 is provided with multiple, the dispersed side being arranged on chain folder 10 cooling, described cooler 2 is connected to the air intake vent place of blower fan 1, cooler 2 is provided with cooling water pipe 5, during work, the natural wind sucked by blower fan 1 cools in cooler 2, and arrive each blowing mouth 3 place to chain folder 10 cooling by airduct 4.Multiple blowing mouth 3 arranges one along the side of chain folder 10 cooling at interval of 1m.The internal diameter of described airduct 4 and blower fan 1, cooler 2 and blowing mouth 3 match.Every bar chain clipping system is equipped with the driving 11 of chain folder, lays respectively at the exit of baking oven 9.
Be described further below in conjunction with concrete actual conditions, in the work of Biaxial Oriented Plastic Film Line, film after longitudinal stretching enters cross directional stretch section, film is by the preheating of preheating zone 6, temperature starts to rise gradually, in cross directional stretch district 7 to be entered, chain folder 10 starts to carry out at the uniform velocity cross directional stretch to film, and now the temperature of chain folder 10 starts remarkable rising; And enter in heat set zone 8, because the cross directional stretch sizing of film needs very high temperature, under this just makes heat set zone 8 be in hot conditions always, now, the temperature of chain folder 10 can raise further.Chain folder is 10 under high temperature, the state that runs up, and radiating condition is poor, causes temperature too high, and this easily causes film and chain to press from both sides 10 and sticks together and cause rupture of membranes, at all cannot film forming time serious, directly affects the stability of production.
The present invention just shown in Fig. 3 is the cooling system operation principle proposed that solves the problem, and first, by the air quantity regulating the power of blower fan 1 to control to suck natural wind, natural wind enters cooler 2 by airduct 4; Natural wind, in the cooler 2 being provided with cooling water pipe 5, is cooled by exchange heat with cooling water, thus forms cooling air; Then, cooling air arrives each blowing mouth 3 place by airduct 4 and blows cooling to horizontal zip clip 10 under the power of blowing of blower fan 1, this just make chain press from both sides 10 from horizontal draw to export to horizontally draw in the time period of mouth, all the time the state of cooling is in, be conducive to the temperature reducing rapidly chain folder 10 like this, avoid film and chain to press from both sides 10 and stick together.
