detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of new type of valve pocket, comprises body 1 and valve port 4; Described body 1 is connected with valve port 4 viscose glue; PE film 5 is equipped with in described body 1 and valve port 4; Described PE film 5 is provided with the micropore 9 with degassing function, makes PE film have the function of exhaust by micropore; The edge of described micropore 9 is provided with protruding lint circle 10;
Described valve port is combined by paper layer 6, PE rete 5 and paper composite bed 7; Described paper layer 6, PE rete 5 and paper composite bed 7 set gradually from inside to outside; The outside of described paper layer 6 is provided with glue layer, is the first glue layer; Described paper layer 6 is bonded together by this first glue layer and PE rete 5; The outside of described PE rete 5 is also provided with glue layer, is the second glue layer; Described PE rete 5 is bonded together by this second glue layer and paper composite bed 7; Glue 8 is equipped with in described first glue layer, the second glue layer; Described paper layer 6 inside is provided with closed inner bag; The characteristic that the valve-port paper bag of this composite structure has it intrinsic, paper bag improves the tensile strength of paper bag because of built-in PE plastic film entirety, most importantly punches on PE sheet film, makes paper bag have the function of exhaust and have moisture-proof function simultaneously;
Described body 1 is provided with upper base 2, go to the bottom 3 and sidewall; Described upper base 2, go to the bottom 3 and sidewall composition formation hollow bulb; The Polymer PE layer 5 of one deck as moisture proof barrier is also provided with in hollow bulb; Described body 1 is also combined by paper layer 6, PE rete 5 and paper composite bed 7; Paper layer 6, PE rete 5 and paper composite bed 7 crowd around synthesis tubular, in the seam mutual dislocation of three, form the shape of ladder; All scribble glue 8 at the seam of three, when PE rete 5 and paper layer 6 and paper composite bed 7 close up form tubular after the shape of ladder can ensure the bonding firmness of its head and the tail joint; Described upper base 2 is provided with socket groove; Described valve port 4 is arranged in socket groove, and is bonded together with upper base 2; Insert in this socket groove after folded inverted valve port 4 after material filling and just can close valve-port paper bag;
Described upper base 2 and go to the bottom 3 shape be rectangle; Described sidewall is made up of paper layer 6 and paper composite bed 7; Glue layer is provided with in described paper layer 6; Glue 8 is provided with in described glue layer; Described paper layer 6 is bonded together with paper composite bed 7 by the glue 8 in this glue layer;
Described PE film 5 is the High molecular material PE film of one deck energy protection against the tide;
Described PE film 5 is polyethylene film;
At Polymer PE rete 5, be equipped with micropore 9 for being vented, and Polymer PE rete 5 is positioned in the middle of the interlayer of paper layer 6 and paper composite bed 7, so just ensure the unimpeded of micropore 9 exhaust on PE rete 5, because nano-powder material is when Vessel in Negative Pressure Filling, its most material intercepts in the inner side of paper layer 6 through paper layer 6 by its nano-powder, and gas permeation paper layer 6 discharging to paper bag skin progressively;
Micropore 9 on PE rete 5 punches from the internal layer outer layers of PE rete 5, thus the protruding lint circle 10 of a circle is defined at the edge of the micropore 9 of PE rete 5, when PE rete 5 is together with paper layer 6 inner stacks, the protruding lint circle 10 of PE rete 5 outside will be pushed back micropore 9, micropore 9 is blocked, PE rete 5 is recovered again original sealing characteristics, guarantees the anti-soak properties in material storing process;
The valve-port paper bag structure of PE sheet film punching Quick air-discharge, has the characteristic of protection against the tide, tension and Quick air-discharge, the valve-port paper bag structure of this PE sheet film punching Quick air-discharge, the manner of packing that nano-powder material all adopts flowing water Vessel in Negative Pressure Filling can be applicable to, nano-powder crystal grain can be sucked in coated paper envelope along with air-flow in filling, because filling speed is fast, filling charge flow rate must be directly proportional to the extraction flow of coated paper envelope, as coated paper envelope has exhaust not smooth, paper bag will form bulge, but material also will just be got lodged in delivery duct by air-flow, reduce filling production efficiency, when paper bag internal gas pressure is greater than the tensile strength of paper bag body material, paper bag will be broken through formation bale broken by air-flow, nano-powder also can spray with air-flow together in paper bag, what the dust sprayed was serious pollutes environment, which results in the failure of nano-powder flowing water canning means, but due to the valve-port paper bag structure of PE sheet film punching Quick air-discharge, air in paper bag is passed PE film by the micropore fast speed of PE film, change the sir-tight characteristic of PE plastic film, the strong PE plastic film that solves can only can not to be breathed freely defect at paper bag internal layer in protection against the tide, the valve-port paper bag of favourable solution core band plastics PE, the pioneering technology of the smooth filling nano-powder material of energy.There is the valve-port paper bag of PE sheet film punching Quick air-discharge, smoothly air can be discharged in paper bag under the environment of its high negative pressure, and nano-powder material can not be discharged with air, and the paper+PE plastic film+paper being through paper bag filters layer by layer in paper bag, the improvement of PE film punching valve-port paper bag up-to-date technology reaches the technological requirement of nano-powder Vessel in Negative Pressure Filling, effectively raise filling production efficiency, have also been changed nano-powder filling time ejection contaminated environment defect, effectively reduce the cost of the whole production chain of nano-powder material, and low being convenient to of valve-port paper bag productive costs with PE sheet film punching Quick air-discharge is promoted.
The present invention is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, done all conversion, all drop within protection scope of the present invention.
