Two invention optimal combinations shown in Figure 14,11,12 and 13.
Vacuum seal bag does not have the controlled valve of bleeding, and sack does not have interior slide fastener, preferably adopts the common plastics bag.
As shown in figure 15, raised line 44 is established as the leak stopping weighting material to crack 09 in the both sides of extraction pipe.As shown in figure 16, snare one pipeline 45 around the extraction pipe, pipeline 45 only communicates with the vacuum bag inner chamber with cavity between the extraction pipe, and extruding vacuum bag 06, the outer wall of pipeline 45 are close to the vacuum bag inwall and are formed leak stopping weighting material to crack 09.
With reference to Figure 17, establish rubber-like packing seal 47 in the inboard of the clamp bar 46 of anchor clamps, clamp bar crush seal pad also pushes vacuum bag 06 outer wall, eliminates the crack 09 between vacuum bag inwall and the extraction pipe.The middle part that is preferably in clamp bar is shaped on arc groove 48, more easily eliminates crack 09.
After vacuum is finished, extract extraction pipe out, 47 upper and lower closing up of packing seal, sealing sack.Preferably with reference to Figure 18, common interior clamp bar 49 and outer clamp bar 50 clamp the sack of having finished vacuum by prior art, replace the anchor clamps among Figure 17.Reclaim usefulness again, vacuum bag leak free cost is reduced greatly.With reference to Figure 19,20, packing seal 51 extruding of inside and outside clamp bar and the crack 09 between elimination extraction pipe and the vacuum bag, aspiration vacuum is extracted extraction pipe, anchor clamps automatic seal sack out after vacuum is finished.
With reference to Figure 21, clamp bar 46 is plane, adopts elastomeric material, produces leak stopping weighting material 44 by elastic deformation, preferably establishes packing seal; Perhaps with reference to Figure 22, riglet is established arc groove 48, makes leak stopping weighting material 44; Or, in having the clamp bar of arc groove, establish packing seal 47 with reference to Figure 23, and when clamping conduit, producing the leak stopping weighting material by deformation, behind the extraction conduit, packing seal clamps the sealing of vacuum sack.With reference to Figure 24, packing seal in the anchor clamps is divided into two groups, when conduit has just detached one group of (short dash line is illustrated in the vacuum bag lower part) packing seal 471 in partially of sack, packing seal in this bag resiles and clamps the vacuum bag sealing, and this moment, conduit did not detach the seal stack pad 472 at nearly sack edge as yet, had prevented that conduit from detaching the moment sack gas leakage of sack.
According to above-mentioned (10) described fast vacuum sealing method, the vacuum sack of having finished vacuum seals, perhaps establish rectangular sealing band 460 (representing with long dotted line among Figure 24) at the inside face of clamp bar 46, in case conduit detaches sealing band, further clamp clamp bar, the sealing band of upper and lower clamp bar clamps smooth in the linear sealing mode or around the overlapping sack outer wall of conduit, perhaps, other changes anchor clamps shown in Figure 180 and seals, and sealing effectiveness is better.With reference to Figure 25, the last clamp bar 461 of anchor clamps upwards opens around axle 52, and the vacuum sack is placed on down above the clamp bar 462, and conduit puts in vacuum bag, and last clamp bar closes up with following clamp bar downwards, and fastener 53 clamps upper and lower clamp bar, and the leak stopping weighting material in the clamp bar is eliminated crack 09.After vacuum is finished, further clamp the heat-sealing of upper and lower clamp bar or sack or change lower-cost anchor clamps shown in Figure 180 in addition.The most handy plastic bag of vacuum bag.
0.80 yuan every of interior slide fastener plastic bag is used instead on year-on-year basis and is not had 0.035 yuan every of interior slide fastener food plastic freshness protection package, and cost reduces by 25 times, but inside and outside or upper and lower clamp bar repeated use.The present invention has solved key issue for plastic bag vacuum seal, promptly the plastic bag vacuum sealing technology in plastic bag central authorities bag wall installation evacuating valve or the expensive difficult operation of slide fastener in plastics sack system is changed into and adopt the simplest common plastic bag to carry out fast vacuum sealing, packing cost is extremely low.But large-scale popularization.
With reference to Figure 26, at interior clamp bar 49 during with outer clamp bar 50 assemblings or when clamping the sack of vacuum bag, the end state of inside and outside clamp bar phase clamping is taked short, the long configuration.Being convenient to finger when needing separately oppositely exerts all one's strength to inside and outside clamp bar respectively.Omit more than the long 5mm than interior clamp bar top 55 at preferably outer clamp bar top 54, pinches outer clamp bar on the other hand, hole in the clamp bar in another hand puts in bar-shaped hard thing, both hands are oppositely exerted all one's strength, bar type is pried open interior clamp bar end, and inside and outside clamp bar end easily separates, and inside and outside clamp bar has separately just made things convenient for.Perhaps, adopt the clamp bar disconnector to separate inside and outside clamp bar end.The clamp bar disconnector is made up of the interior bar described in (17), outer bar and interior bar and turnover joint portion three parts of outer bar, specifically with multiple ways of realization such as tongers.
