Content of the invention
The present invention proposes a kind of ventilated membrane and stretches online printing process, solves independent stretcher and pressure in prior artThe problem that stricture of vagina equipment cost is high, take up space.
A kind of ventilated membrane of the present invention stretches online printing process, including step：
S1：Ventilated membrane enters stretching deep Embosser online by input equipment；
S2：In drawing process, before entering drying tunnel, ventilated membrane is printed；
S3：Winding is exported by outut device.
Wherein, described step S2 includes：Using in the preassembled print cartridge in drying tunnel porch, drop roller and print roller to saturatingAir film is printed, and wherein, drop roller is located in print cartridge, and tangent with described print roller, described print roller and drying tunnel arrival endTransmission wheel tangent.
Wherein, described drying tunnel length is 1200mm.
Wherein, in described drying tunnel, temperature is 40 DEG C～45 DEG C.
Wherein, the pattern depth of described printing roller surface is 20 μm～23 μm.
The ventilated membrane of the present invention stretches online printing process to be passed through, before entering drying tunnel, to print after printing pattern on ventilated membraneDirectly carry out drying tunnel after decorative pattern processed film and oil film to be toasted so that stretching and embossing complete in singlepass simultaneously, improve lifeProduce efficiency, save the space hold of production cost and factory.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, completeSite preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based onEmbodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative workEmbodiment, broadly falls into the scope of protection of the invention.
As shown in figure 1, the ventilated membrane of the present embodiment stretches online printing process including：
Step S1, ventilated membrane enters stretching deep Embosser online by input equipment.As shown in Fig. 2 the present embodimentDeep Embosser includes online for a kind of stretching：Ventilated membrane input equipment 1, ventilated membrane outut device 3 and be located at ventilated membrane input setStandby stretcher 2 between 1 and ventilated membrane outut device 3.Stretcher 2 is provided with column and crossbeam, and column and crossbeam are provided withSome transmission wheels, ventilated membrane 4 transmits between transmission wheel, thus reaching the purpose of stretching.At least one column is provided with drying tunnel 5,For toasting ventilated membrane, to contribute to stretching.
Step S2, in drawing process, prints to ventilated membrane before entering drying tunnel.
Step S3, exports winding by outut device.
The ventilated membrane of the present invention stretches online printing process and passes through before entering drying tunnel 5, after printing pattern on ventilated membrane 4Directly carry out drying tunnel 5 after printing pattern film and ink to be toasted so that stretching and embossing complete in singlepass simultaneously, improveProduction efficiency, save the space hold of production cost and factory.
Ventilative film raw material component by weight includes：Calcium carbonate granule 50%～70%, pe metallocene 48%～28%, remainingFor auxiliary agent, antioxidant, Tissuemat E and heat stabilizer, can mix in any proportion.Such ventilated membrane hydrostatic pressure resistant and physicsTensile strength more preferably, is more suitable in line drawing and printing.
In the present embodiment, step S2 includes：Using in the preassembled print cartridge in the porch of drying tunnel 56, drop roller 7 and printBrush roll 8 prints to ventilated membrane, and wherein, drop roller 7 is located in print cartridge 8, and tangent with print roller 8, print roller 8 and drying tunnel 5Arrival end transmission wheel tangent.Drop roller 4 connects the actuating unit of stretcher, that is, passing through the mechanism such as conveyer belt or gear willThe actuating unit of drop roller 4 stretcher, rotates for drop roller 4.Wherein, print roller 8 can be its of former stretcher 2In a transmission wheel, the surface of transmission wheel carves decorative pattern, becomes print roller 8
In the present embodiment, toast ink thereon again due to ventilated membrane 4 should be toasted, the length of drying tunnel 5 is 1200mm,Lengthen with respect to existing drying tunnel, thus increasing the time of baking.
In drying tunnel 5, temperature is preferably 40 DEG C～45 DEG C, so can dry ink and thoroughly in limited drying tunnel lengthAir film will not damage ventilated membrane because of overheated again.
In the present embodiment, the pattern depth on the surface of print roller 8 is 20 μm～23 μm, relatively existing independent printing equipmentPrint roller pattern depth reduced.This depth enables ink uniformly to print, and can save ink again, and can make oilInk is quickly thoroughly dried.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all spirit in the present invention andWithin principle, any modification, equivalent substitution and improvement made etc., should be included within the scope of the present invention.
