Abstract
The invention discloses a processing system of a bacteriostatic PE film easy to tear. A thin film prepared through a film blowing machine enters the space between guide groove work segments of two guide rails and is heated by an air heating mechanism to about 140 DEG C; under the driving of a chain wheel mechanism, a clamp changes into a clamped state from an opening state when entering the guide groove work segments, and the two side edges of the thin film are clamped; and the clamp continues to run along the guide rails, while the interval between the two guide rails is gradually increased, the width of the portion, clamped by the clamp, of the thin film is transversely expanded by 20%, and then the thin film is cooled, sized and wound through an air cooling mechanism. The molecular structure of the PE film which is transversely expanded is effectively sorted and changes into an orderly cross-linking state from a disorder state, and therefore the PE film can be easily torn linearly. The bacteriostatic PE film easy to tear is processed through a simple mechanism compatible with the film blowing machine, and work is stable and reliable. Meanwhile, the prepared PE film easy to tear has the bacteriostatic effect and serves as packaging materials of food, medicine and the like, and addition of antiseptic agents can be unnecessary.
Description
Technical field
The present invention relates to one and easily tear antibacterial PE film system of processing.
Background technology
PE film and polyethylene film.Its production procedure is, first the polyethylene particles of drying is added in hopper, weight by particle itself enters screw rod transmission from hopper, in course of conveying, because plastics and screw rod, friction between plastics and machine barrel and interparticle collision rub, also progressively dissolve due to barrel external heat simultaneously.The plastic warp head screen pack decontamination of melting from die head die orifice out, through inflation, vane cooling after through collapser pressure, batch finished product film roll by carry-over pinch rolls and make cylinder.
Existing PE film due to molecular structure in film be out of order cross-linked state.When needing to tear use, not easily openable, even if tear its tear line distortion confusion, causes trouble to user.Simultaneously as packaging material, the bacteriostasis property of market to film it is also proposed requirement, but, possess simultaneously and easily tear and the packaging PE film of antibacterial complex function effect or the blank spot in market.Exploitation drops into special equipment cost comparatively greatly, and meeting the need of market to existing equipment transformation is the problem faced in the industry.
Summary of the invention
In order to solve above-mentioned drawback, technical problem to be solved by this invention, be to provide a kind of system of processing of easily tearing antibacterial PE film, the film obtained easily is torn, and tear line linearly, and has fungistatic effect.In order to solve above-mentioned drawback, the technical solution used in the present invention is, one easily tears antibacterial PE film system of processing, comprises the inflation film manufacturing machine formed primarily of extruder, die head, overhead extension roller, guiding roller group and rolling-up mechanism; It is characterized in that, the polyethylene particles added in described extruder is mixed with antibacterial material, and both mixed weight ratios are: polyethylene particles: antibacterial material=3:2; Described antibacterial material is selected from the one in chlorhexidine acetate, vanillic aldehyde or ethyl vanillin aldehyde compound;
Wind-heat mechanism, cross directional stretch mechanism and air cooling mechanism is sequentially provided with between described guiding roller group and rolling-up mechanism; The hot blast operating temperature of described wind-heat mechanism is 140 DEG C;
Described cross directional stretch mechanism comprises the guide rail that two lay respectively at the symmetrical mounting of film both sides, and two guide rails are provided with the guide groove that opening is arranged in opposite directions towards the side of film; Article two, the spacing between guide rail is left end by film upstream end to film and is increased gradually: the spacing film upstream end two guide rails is S1, and the spacing left between end two guide rails at film is S2, S1:S2=1:1.2;
Some clips clamping film side are clouded in guide groove, the chain of described clip connection chain wheel mechanism, and described guide groove is by the cyclic track of active section and inoperative section forming closed, and under the driving of chain-wheel mechanism, clip moves along cyclic track; The guide groove of active section makes clip be clamped condition, and the guide groove of inoperative section makes the open-shaped state of clip, and the active section of described guide groove is parallel with film side.
Adopt technique scheme, the film that inflation film manufacturing machine obtains is under blowing and rolling-up mechanism effect, and film enters between the guide groove active section of two guide rails, and by wind-heat mechanism heats to about 140 DEG C; Under the driving of chain-wheel mechanism, when clip enters guide groove active section, become clamped condition from open configuration, clamp the dual-side of film; Clip continues to run along guide rail, and along with the increase gradually of the spacing between two guide rails, the film cross directional stretch width 20% that clip is clamped, then film is through air cooling mechanism cooling and shaping, rolling.Through the PE film of cross directional stretch, its molecular structure obtains effective arrangement, becomes orderly cross-linked state from out of order cross-linked state, thus can linearly tear easily.
As from the foregoing, beneficial effect of the present invention is, by achieving antibacterial processing of easily tearing PE film with the simple mechanism of inflation film manufacturing machine compatibility, working stability is reliable.The easily tore film simultaneously obtained also has fungistatic effect, and the packaging material as food, medicine etc. use, and can not need to add anticorrisive agent.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.

Detailed description of the invention
See accompanying drawing, reflect a kind of concrete structure of the present invention.Describedly easily tear antibacterial PE film system of processing and comprise the inflation film manufacturing machine that extruder 1, die head 2, overhead extension roller 9, guiding roller group 15 and rolling-up mechanism 16 form.The polyethylene particles added in described extruder 1 is mixed with antibacterial material, and both mixed weight ratios are: polyethylene particles: antibacterial material=3:2; Described antibacterial material is selected from the one in chlorhexidine acetate, vanillic aldehyde or ethyl vanillin aldehyde compound.
Between described guiding roller group 15 and rolling-up mechanism 16, be sequentially provided with the air cooling mechanism that the wind-heat mechanism of air outlet 4 and blast pipe 11 formation, cross directional stretch mechanism, air outlet 5 and blast pipe 6 are formed.The hot blast operating temperature of described wind-heat mechanism is 140 DEG C; Frame 12 is arranged the guide roller set 14 of support film 3.
Described cross directional stretch mechanism comprises two guide rail 7, two guide rails 7 laying respectively at the symmetrical mounting of film 3 both sides and is provided with the guide groove 71 that opening arranges in opposite directions towards the side of film 3; Article two, the spacing between guide rail 7 is left end by film upstream end to film and is increased gradually: the spacing film upstream end two guide rails 7 is S1, and the spacing left between end two guide rails 7 at film is S2, S1:S2=1:1.2.
