Because small dimension metallized film screen band is more, on the metallized film of such as 28 specifications, nearly 21, screen band, 28cm of being only separated by between two screen bands.Because the distribution of screen band is closeer, nozzle quantity on corresponding baffle plate is many, the oil mass of required supply is larger, the as easy as rolling off a log spray equipment internal pressure that causes is uneven, easily cause the nozzle pressure away from spray equipment oil inlet end inadequate, oil mass supply is insufficient, corresponding blank is caused to stay both sides, border area oil mass on the low side, thus the oil in this region fully can not stop the absorption of metal, make metal plating and the fuzzy blackout of screen belt edge, after making electrical condenser, condenser capacity loss can be caused large, directly affect quality product.In order to address this problem, must ensure that the oil mass supply shielding oil is abundant, this just needs to improve the steam output that heating oil pipe temperature increases oil.And improve Heating temperature, although can improve the steam output of oil, oil pipe temperature is too high, easily cause film to scald, and in oil pipe chamber, pressure is large, oily vapour activity is large, very easily being splashed to blank through nozzle stays border area with exterior domain, causes film oil pollution, affects metalized film quality.
Summary of the invention
The object of the invention is to propose a kind of spray equipment baffle plate for the formation of metallized film screen band, effectively can solve small dimension metallized film and shield the fuzzy On Blackening of belt edge after causing plated film due to closeer, each nozzle oil vapour inequality of screen band distribution, the capacitive property of metallized film can be improved.
For achieving the above object, present invention employs following technical scheme:
For the formation of the spray equipment baffle plate of metallized film screen band, the air storing cavity storing shielding oil vapour is provided with inside described baffle plate, baffle plate is provided with the nozzle to film surface spraying shielding oil distributed along its length, the nozzle opening communicated with air storing cavity is had in the middle of nozzle, air storing cavity top is provided with point air storing cavity being used for compensator or trimmer pressure of enlargement in section at the nozzle opening entrance end of each nozzle, and the degree of depth of point air storing cavity is at 0.1 ~ 0.15cm.Owing to being provided with a point air storing cavity inside each nozzle, make to be provided with pressure buffer region between spray equipment inner chamber and each nozzle, thus the oil vapour pressure of each nozzle is reached unanimity, do not need to increase oil vapour pressure by heating, thus eliminate the fuzzy On Blackening of metalized film screen belt edge brought thus.
Grinding tool evaporation small dimension metallized film after improvement, due to screen band, mouth place increases circular groove, storage oil mass is many, oil is easy to fully be evaporated to film from screen band Kou Chu region, too high oil pipe temperature is not needed yet, make blank stay edge regions oil mass abundant, evaporation small dimension metallized film screen band is clear, thoroughly solves little rule.
Divide the volume size of air storing cavity to decline to each nozzle pressure of buffering to have a direct impact.For making each nozzle oil vapour pressure consistent, the volume of each point of air storing cavity is 3 ~ 6 times of the nozzle opening volume of respective nozzle.
Consider that the nozzle oil vapour pressure away from spray equipment oil inlet end is easily not enough, the volume of each point of air storing cavity is increased to centre gradually by two ends.
Beneficial effect of the present invention is: by being provided with a point air storing cavity inside nozzle, make to be provided with pressure buffer region between spray equipment inner chamber and each nozzle, thus the oil pressure of each nozzle is reached unanimity, do not need to increase oil vapour pressure, thus eliminate the fuzzy On Blackening of lattice metalized film screen belt edge brought thus, improve the electric property of metallized film, the condenser capacity made is stablized, and quality is obviously improved.In addition, by arranging suitable point air storing cavity volume, the pressure reduction between each nozzle can be eliminated further, making respectively to stay border area to spray uniformity, metallized film quality can be improved.The present invention is applicable to 60-9 gauge metal film.
