Abstract
The utility model discloses a high-precision film laminating machine manufacturing film laminating filter material with high gas permeability. The high-precision film laminating machine comprises an upper film laminating hot roller, a lower film laminating hot roller and a frame, wherein the surface of one of the roller cylinders of the film laminating hot rollers is a smooth roller; the surface of the other roller cylinder is provided with concave-convex patterns; the area of the convex part of the patterns is smaller than that of the concave part. The high-precision film laminating machine solves the problem that conventional film laminating manners greatly reduce gas permeability of film laminating filter material after film laminating; film breaking phenomenon is not easy to occur in film laminating; film laminating effect is good.
Description
Technical field
The utility model relates to microporous teflon membran coated filter material manufacturing equipment, particularly a kind of high accuracy laminating machine of manufacturing highly-breathable coated filter material.
Background technology
The advantages such as good coated filter material must have that filter efficiency is high, running resistance is little, long service life, deashing are easy, can be used as industrial smoke filtering material for industrial dedusting field, this just requires coated filter material both to have higher filter efficiency also to have higher laminating fastness.
There is following defect in laminating machine of the prior art:
1, the base material of coated filter material and the gas permeability of polytetrafluoroethylmicroporous microporous membrane are all very high separately, but by the coated filter material gas permeability that the two laminating making obtains, can greatly reduce in prior art, no matter are that gluing is laminating or mirror roller high temperature hot pressing is laminating.Organic gel in the laminating technology of gluing can block most of micropore of microporous teflon membran; Minute surface hot-rolling in the laminating technology of mirror roller high temperature hot pressing can make most of micropore thawing of microporous teflon membran block equally, so can significantly reduce with the Air permenbility of the coated filter material of these old fabrication techniques, if microporous teflon membran air penetrability used is 10-20cm/s(127Pa), the air penetrability of laminating rear coated filter material can only reach 2 ~ 5cm/s(127Pa).
2, film placing mechanism only has a unreeling shaft to add a spreading roll conventionally, the horizontal tension of controlling diaphragm roughly, the longitudinal tension force of film is uncontrollable, likely can excessively because of the longitudinal tension force of film cause laminating rear generation film to split phenomenon, such coated filter material in use its surface filtration function can lose efficacy very soon, duster system running resistance is increased, and energy consumption increases.
3, common laminating roller is configured to a minute surface hot-rolling and coordinates with a silica gel roller, mirror roller operating temperature is for a long time at 300 ° more than C, the silica gel roller coordinating is with it easy to aging distortion, cracking, and will again be coated silica gel outer basic half a year, and maintenance cost is produced, increased in impact continuously; Silica gel roller can not heat in addition, to entering cloth, does not have pre-heat effect, all unfavorable to improving laminating fastness and speed of production.
4, laminating roller roller gap degree of regulation is low, and can not be held, manual adjustments gap mostly, in prior art, also there is the mode that adopts oil cylinder oscillating arm mechanisms dancer rools spacing, yet, although this mechanism that controls compound fastness by oil pressure can make roller move more effortlessly, cannot realize the precision of spacing and control, easily make base material and microporous barrier be squished or laminating fastness inadequate.
5, in order to enhance productivity, the door width of base material is also more and more wider, if the laminating roller rigidity of wide cut laminating machine is large not, the overlay film roller of insufficient rigidity when laminating that pressurizes may produce amount of deflection intermediate muster, make 2 overlay film rollers not parallel, cause the laminating fastness of mid portion reduce or be not covered with completely.
So existing laminating machine cannot meet the requirement of the coated filter material of the high laminating fastness of the required filtration efficiency of modern industry.
Summary of the invention
