Description
Technical field
This utility model is related to a kind of perforating device of perforated film, the vacuum punching dress of particularly a kind of perforated film
Put.
Background technology
Perforated film is widely used in the surface layer of sanitary towel and sanitary pad, that is, usually said liquid absorbing net face.But open
Hole thin film has plastic sense, and flexibility is not good enough, the shortcomings of infiltration rate is slow, in order to improve these shortcomings,
A kind of eyelet touch membrane structure is mentioned, it is to extend in oriented second face in the first face of thin film in CN200620057798.4
Pore, this pore forms the thin film angle of projection on the second face of thin film:Simultaneously to the first face shape on thin film second face
Become the larger micropore of perforated area, the second face of thin film is when thin film is applied as the use front with contact human skin.Just
It is that these thin film angles projection can make the reverse side of thin film form rough " matte " to utilize this " matte " as being applied to health use
The front of product, can increase the contact resilient of film product and skin, improve the comfortableness using, and aperture and macropore are simultaneously
Deposit, increased infiltration rate.Application number：Also this kind of thin film is mentioned in CN200380101939.7 patent, and in order to keep little
Hole is not crushed when forming macropore, closure, so to carry out protecting aperture using having heat ray filter when macropore is formed.But
All carried out using off-line secondary hole knockout at present, as shown in Figure 1A, Figure 1B, casting films 1 are carried out through vacuum punch device first
Form the perforated film 2 with small structure after punching, then wind.To have foraminate perforated film 2 and adopt unwinding equipment
Unreel, carry out secondary punching through mechanical punching equipment 3, form macropore, thus winding, formation has aperture and the perforate of macropore is thin
Film 4.Why adopt secondary hole knockout, broken mainly due to during machining small, needing vacuum at high temperature to inhale, become
Perforated film sizing after type is relatively slow, needs longer operation to carry out solidifying and setting, could keep aperture fine hair in mechanical punching mistake
Be not crushed in journey deformation, closure, otherwise can affect absorbability and the sense of touch of perforated film.But this production method is due to being two
Secondary processing, first winds after needing to form aperture thin film, after transporting mechanical punching former, then unreels, therefore energy consumption is larger,
And easily causing material contamination in transportation, waste of material is more.And application number：200610092425.5 disclosed in patent
A kind of manufacture method of secondary mesh combined plastic punched film although this production technology is secondary drilling technology online, but
Before secondary operations, aperture fine hair cannot effectively solidify, and sizing, so aperture fine hair easily flattens change in secondary operations
Shape, closure, thus affect the feel of perforated film and the permeance property of actually used middle liquid.
Utility model content
The purpose of this utility model is to overcome drawbacks described above, proposes a kind of vacuum perforating device of perforated film, its dozen
Cooling work can be carried out so that aperture fine hair is effectively solidified and shapes before secondary operations while hole.
For achieving the above object, solution of the present utility model is：
A kind of vacuum perforating device of perforated film, including vacuum forming drum, supersonic atomizer and molding cylinder mould, its
It is structurally characterized in that, described vacuum forming drum has the suction mouth region of the side positioned at vacuum forming drum, and described is ultrasonic
Ripple atomising device is located at the right opposite in suction mouth region, and described molding cylinder mould is located at the outside of vacuum forming drum.
Further, described supersonic atomizer and the distance in the horizontal direction in suction mouth region are 5-
200mm.
Further, described molding cylinder mould is every square centimeter 20～1600 holes.
After above-mentioned vacuum perforating device, the thin film in suction mouth region after the effect perforate of external and internal pressure difference, by
It is located close to the right opposite in suction mouth region in supersonic atomizer, the moisture of atomization makes to be sucked by suction mouth region
Air humidity raise, thus when the attachment of moisture of in the air is on the perforated film have high temperature, water vapour can be formed,
Because the process that water becomes vapor is endothermic process, the substantial amounts of heat on perforated film surface therefore can be taken away so as to surface
Temperature can decline rapidly, and surface temperature can quickly fall to less than 50 DEG C, thus accelerating aperture fine hair to shape, in the machine of entrance
Deformation will not be crushed so that the punching of aperture vacuum produces and macropore mechanical punching produces and realizes Fast synchronization in tool shaped device
Produce.Meanwhile, the use of this this vacuum perforating device sets so that saving winding device during producing thin film with unreeling
Standby and transit link, plays saving energy consumption, reduces cost, improve production efficiency, prevents the effect of material secondary pollution.

Specific embodiment
In order to the technical solution of the utility model is explained further, this utility model is entered below by specific embodiment
Row elaborates.
Cooperation Fig. 2, the vacuum perforating device of the perforated film that this utility model discloses, including vacuum forming drum 8, ultrasound wave
Atomising device 6 and molding cylinder mould 7, wherein, the vacuum that described vacuum forming drum 8 has positioned at the side of vacuum forming drum 8 is inhaled
Mouth region domain 5, described supersonic atomizer 6 is located at the right opposite in suction mouth region 5, and described molding cylinder mould 7 is located at true
The outside of empty assembly drum 8.
Carrying out thin film boring method using this vacuum perforating device is：Casting films 1 enter this vacuum perforating device, in molding
The suction mouth region 5 of drum, due to inside and outside differential pressure effect, forms the perforated film 2 with aperture 9, and meanwhile, ultrasonic fog is disguised
Put 6, the moisture of atomization makes the humidity of the air being sucked by suction mouth region 5 increase, and the attachment of moisture working as in the air exists
When having on the perforated film 2 of high temperature, water vapour can be formed, because the process that water becomes vapor is endothermic process, therefore can
Take away the substantial amounts of heat on perforated film 2 surface, surface temperature can quickly fall to less than 50 DEG C, thus accelerating aperture 9 floss
Hair sizing, after being conducive to directly winding, pass keeps, or the holding being processed further process mesothyrid again.
Embodiment 1
