Abstract

The utility model relates to a boring film combiner, comprising a combiner body, a blower fan, a screen roller the outer side of a heater box of which is provided with a notch, and an inner cavity of the screen roller is divided into two parts which are respectively connected with a vacuum pump and the blower fan, the periphery of the screen roller is provided with a metal net. Boring film fabrics which are manufactured by the utility model has the advantages of high yield, good quality, no reverse permeability, and comfortable sensation, and is especially suitable for disposable sanitary articles in a higher grade.

Description

The making hole film combination machine

The utility model relates to the nonwoven mechanical field, particularly a kind of equipment that is used for production reticulated cell film lining such as disposable sanitary articles lining.

One deck lining that present disposable sanitary articles such as sanltary towel, diaper are pressed close to skin most is to adopt non-woven material a bit, it has good penetrability, feels soft advantage, but also there is the shortcoming of easy counter-infiltration (being that liquid infiltrates behind the nexine if measure more meeting reverse osmosis to the top layer) simultaneously, not only the people done not feel like oneself but also unhygienic.In order to solve the shortcoming of counter-infiltration, making hole film is generally adopted on the top layer of this type of amenities now, promptly on plastic sheeting, punch, this type of hole has topological structure, be that the outer layer surface aperture is big, the inner layer surface aperture is little, thereby, be difficult for reverse osmosis behind the liquid infiltration internal layer and appear the top layer of this making hole film as amenities.Present above-mentioned making hole film all adopts the acupuncture moulding process, and with the mode acanthopore on plastic sheeting that is similar to mold pressing, its percent opening is low, influences its counter-infiltration performance, can form burr at the film internal layer face after the perforate, reduces the skin comfort level.

The purpose of this utility model is at above-mentioned shortcoming, designs and a kind ofly produce no counter-infiltration, feels the making hole film combination machine of the comfortable making hole film lining that is used for disposable sanitary articles.

The technical scheme that realizes above-mentioned purpose is as follows: the making hole film combination machine, has body, be fixed with the blowing blower fan on the body, be fastened on the heating cabinet of internal body by airduct, the body of heating cabinet below is provided with the net roller, by its rotation of driven by motor fixing on the body, net roller periphery is the wire netting with reticulated cell, the net roller has hollow cavity, the net roller that is in the wire netting is vacuum chamber and common pressure chamber two parts by a barrier partitions, and wherein vacuum chamber connects with vavuum pump by vacuum cooling tank, and the sidewall of this vacuum chamber part net roller has the vacuum notch, and common pressure chamber communicates with breeze fan, and the sidewall of this common pressure chamber part net roller has the air-supply notch.As the further technical measures of aforementioned schemes, on the body of described net roller both sides, be fixed with the raw material winding up roller respectively and become winding up roller.

As the further technical measures of aforementioned schemes, the net roller periphery in wire netting inside is provided with adjustable plate.

Further, the mesh of described wire netting, it is with the aperture greater than inner surface, the aperture of outer surface.

Further again, the inside and outside surface of described mesh is a regular hexagon, and the centre distance of adjacent two mesh all equates.

The utility model according to such scheme and measure, the wire netting place of plastic sheeting above vacuum chamber by the blower fan of drying blow to the hot air (can reach 150 degree) that produces of heating cabinet, simultaneously because the effect of vavuum pump, by the vacuum notch, make and produce strong negative pressure between vacuum chamber and wire netting, make the film that is in wire netting mesh place under high temperature and strong negative pressure, aspirate pore-forming, this membrane pores is the little topology hole of outer imperial palace, the mesh of wire netting is set identical on unit are with the hole count of membrane pores, like this, the film at raw material winding up roller place to becoming the winding up roller place, promptly becomes the finished product making hole film through the net roller.The making hole film lining that utilizes the utility model to produce, the yield rate height, quality is good, and no counter-infiltration and feel comfortable is specially adapted to the disposable sanitary articles of higher gears.According to statistics, the consumption figure of present national sanitary napkin is about 60,000,000,000, wherein 50% adopt nonwoven cloth material, about 20～25% adopt the making hole film lining, promptly have 12,000,000,000 approximately, consume about 10,000 tons of making hole film, and the making hole film lining that utilizes the utility model to produce owing to have above-mentioned advantage, will promote applying of making hole film amenities more, give numerous women, baby with better consideration care, thereby also have bigger social benefit.
