Abstract
The utility model discloses a from air guide vacuum film, including the film body be provided with a plurality of moulding -die corrugation with the product on the internal surface that the film body is used for contacting, adjacent moulding -die corrugation switches on with constitution air guide line each other, the air guide line is the superimposed radial structure of a plurality of decentraction. During the evacuation, this internal air of film is discharged through the air guide line direction that is the superimposed radial structure of a plurality of decentraction, and no matter which region this internal air of film distributes in, the air guide line homoenergetic of the superimposed radial structure of a plurality of decentraction with the shortest route with air escape, improved evacuation efficiency.
Description
Technical field
The utility model relates to film applications, and particularly one is from air guide vacuum film.
Background technology
Common vacuum film needs to carry out air guide in use, traditional air guide method spreads between film and product into air guide nonwoven fabrics to carry out air guide, but this air guide method needs to coordinate air guide nonwoven fabrics, adds productive costs, and add operating procedure, reduce production efficiency.
For this reason, Chinese patent Authorization Notice No. CN202449341U (authorized announcement date is 2012.09.26) is had to disclose a kind of vacuum bag at present, comprise the bag be combined into by two plastic sheetings, this bag is provided with sack, inner side is provided with gas guide groove, and gas guide groove is the pressing mold groove line of bag.This pressing mold groove line is divided into pod line and translot line, and pod line and translot line intersect vertically and formed netted, are positioned at a bag face of vacuum bag.This patent can solve the problem, and when extracting the air in bag with outer pumping vacuum equipment, air flows toward sack direction in pod line and translot line, makes to form vacuum in bag.
But the groove line of above-mentioned patent is the latticed groove line be made up of pod line and translot line, makes the discharge of air be netted flowing, limits the flow direction of air, extend the discharge path of air, reduce the discharge velocity of air, reduces and vacuumize efficiency.
Utility model content
The purpose of this utility model is for shortcomings and deficiencies of the prior art, provides a kind of from air guide vacuum film, should can adapt to difform product, and air guide is respond well, improves and vacuumize efficiency from air guide vacuum film.
The technical matters that the utility model solves can realize by the following technical solutions:
A kind of from air guide vacuum film, comprise film bulk, on the inside face contacted with product, be provided with some pressing mold groove lines at described film bulk, it is characterized in that, adjacent pressing mold groove line mutual conduction is to form air guide lines, and described air guide lines is the radial structure of multiple decentraction superposition.
In a preferred embodiment of the present utility model, groove width and the groove depth of each pressing mold groove line described are not quite identical.
In a preferred embodiment of the present utility model, the groove width of each pressing mold groove line described is 0.3 ~ 0.5mm.
Owing to have employed technical scheme as above, when vacuumizing, air in film bulk is discharged by the air guide lines guiding of the radial structure in multiple decentraction superposition, air-distribution no matter in film bulk is in which region, air all can be discharged with the shortest path by the air guide lines of the radial structure of multiple decentraction superposition, improves and vacuumizes efficiency.In addition, groove width and the groove depth of each pressing mold groove line are not quite identical, can adapt with difform product, ensure that lining endothelium is not easy to leak gas with the corner of product pressing after evacuation.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the birds-eye view of a kind of embodiment of the utility model.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
One shown in Figure 1 is from air guide vacuum film, comprise film bulk 100, some pressing mold groove lines 120 are provided with on the inside face 110 that contacts with product at film bulk 100, adjacent pressing mold groove line 120 mutual conduction is to form air guide lines 130, and air guide lines 130 is in the radial structure of multiple decentraction superposition.When vacuumizing, air in film bulk 100 is led by the air guide lines 130 of the radial structure in multiple decentraction superposition and discharges, air-distribution no matter in film bulk 100 is in which region, air all can through being adjacent nearest radial structure center 131 and branch road 132 arrives vacuum orifice, so air all can be discharged with the shortest path by the air guide lines of the radial structure of multiple decentraction superposition, improve and vacuumize efficiency.
In addition, adapt with difform product to enable this practicality, ensure that lining endothelium is not easy to leak gas with the corner of product pressing after evacuation, groove width and the groove depth of each the pressing mold groove line 120 in the present embodiment are not quite identical, the groove width of preferred pressing mold groove line 120 is 0.3 ~ 0.5mm, and the groove depth of pressing mold groove line 120 is 0.1 ~ 0.2mm.
More than show and describe groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
