Specific embodiment

To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, and reference Attached drawing, the present invention is described in further detail.

Referring to Fig. 1, it shows that the perspective view of 1 first embodiment of encapsulating die of the present invention, the encapsulating die 1 include a mould Seat 11, the die holder 11 are equipped with the zipper support platform 12 that top surface forms a curved surfaces 13, laterally project one on the curved surfaces 13 The convex mound 14 of strip arc, and convex 14 both ends of mound of the arc are respectively equipped with a front end 141 and a rear end 142, and convex in the arc The rough central location in mound 14 longitudinally opens up the gum-injecting port 15 for being connected to an at least extruder 2.Width, the height on the convex mound 14 of the arc The size of degree and the gum-injecting port 15 is the size of one zipper of foundation to determine, and the settable appropriate power of the encapsulating die 1 is extremely A few heating device, to keep a hot melt elastic gum 21 constantly to maintain molten condition.

As shown in Fig. 2, it shows the perspective view of 1 second embodiment of encapsulating die of the present invention, to provide different size zippers Encapsulating demand, therefore the encapsulating die 1 further comprises a fixing seat 16, the adjacent surface phase of the fixing seat 16 and the die holder 11 To logical equipped with an at least fixation hole (because projection angle relationship is not shown), such as screw hole and an at least connecting hole 111, such as step shape Hole, and a connection piece 112 is utilized, such as screw rod passes through the respectively connecting hole 111, and is locked in the respectively fixation hole, it can be by the mould Seat 11 is installed in the fixing seat 16, or by the die holder 11 from removal in the fixing seat 16.

As shown in figure 3, it shows that a zipper 3 not yet carries out the sectional view before encapsulating process under buckling state, the zipper 3 Including a pair of support strap 31 arranged in parallel, this is to having a gap 313, and the respectively support strap 31 between support strap 31 With one first face 311 being arranged oppositely and one second face 312；And two column continous way buckling component 32 to be respectively set to this right The interior lateral margin in respectively second face 312 of strap 31 is supported, and forms buckling state in 313 position of gap, and respectively arrange adjacent Each one slot 321 of self-forming between the buckling component 32, and respectively the buckling component 32 have a bottom 322, a top layer 323 and One inner cavity 324, and a core wire 325 is arranged in the inner cavity 324.

As shown in figure 4, it shows that the zipper 3 is installed in the schematic diagram of the encapsulating die 1, the side of the encapsulating die 1, example It is led after being equipped with one of a front jocket wheel 41 of a transmission mechanism 4, and the other side, such as rear side then equipped with the transmission mechanism 4 such as front side Wheel 42.The zipper 3 is by the guiding and suppression of the front jocket wheel 41 and the rear guide wheel 42 to be covered on the encapsulating die 1 The curved surfaces 13.The zipper 3 is covered in the strength on the convex mound 14 of the arc and the filling of the hot melt elastic gum 21 is pressed into direct ratio, It is covered on the convex mound 14 of the arc that is can adjust the zipper 3 by the different location of the front jocket wheel 41 and the rear guide wheel 42 Strength, thus adjust the filling pressure of the hot melt elastic gum 21.Furthermore also can adjust by the high and low position of the rear guide wheel 42 should Height of the hot melt elastic gum 21 in the gap 313；When rear 42 position of guide wheel is lower, the convex mound 14 of the arc can all with The zipper 3 contact；When rear 42 position of guide wheel is higher, the zipper 3 can convex 14 longitudinal length of mound of the arc certain point with The convex mound 14 of the arc separates, therefore the zipper 3 leaves the separation point height on the convex mound 14 of the arc and determines the hot melt elastic gum 21 Height in the gap 313.

Fig. 1, Fig. 4 and Fig. 5 are please referred to, the front end 141 on the convex mound 14 of the arc is roughly the same with the height of the rear end 142, And the front end 141 formed a wedge shaped tip 143, so as to the convex mound 14 of the arc can steadily cut into this to support strap 31 should between In gap 313, enable the gap 313 along convex 14 transverse shifting of mound of the arc.Wherein the height on the convex mound 14 of the arc is less than or waits It is direct to avoid the convex mound 14 of arc of high temperature in the thickness to support strap 31, and by the support strap 31 as separation layer The bottom 322 for touching the two column buckling component 32 causes to damage；Such as this to support cloth tape thickness if 0.55mm, then the arc Convex 14 height of mound of shape is less than or is equal to 0.55mm, but is preferred with 0.50mm or less.When carrying out encapsulating process, by this to support The convex mound 14 of the arc is inserted in the gap 313 of strap 31, which is then given as security the hot melt elastic gum 21 by the gum-injecting port 15 Out and by the gap 313, to pour into the adjacent slot 321 in 32 inside of buckling component and in the gap 313 A part.

As previously mentioned, the convex mound 14 of the arc and the gum-injecting port 15 in the gap 313 are very close to the buckling component 32, therefore via 15 extrusions of the gum-injecting port on the roughly the same convex mound 14 of the arc in such front end 141 and 142 height of rear end The hot melt elastic gum 21 will largely fill in the adjacent slot 321 in 32 inside of buckling component, and rest part A part in the gap 313 to support strap 31.As previously mentioned, can be fitted by adjusting rear 42 high and low position of guide wheel Degree, which adjusts height or even the hot melt elastic gum 21 of the hot melt elastic gum 21 in the gap 313 and further injects into, respectively should In the inner cavity 324 of buckling component 32, make the hot melt bullet being filled in the slot 321, the gap 313 and the inner cavity 324 Property glue 21 link integrally, so as to the buckling component 32 formed best connection relationship.As shown in figure 3, due to the core wire 325 It is set to the inner cavity 324, it is therefore desirable to which by the convex mound 14 of the wider arc and relatively strong filling pressure could be by the hot melt elastic gum 21 pour into the inner cavity 324.

Therefore, if the height on the convex mound 14 of the arc is 0.45mm, this to support strap 31 with a thickness of 0.50mm, then the heat Height of the fusibleness elastic gum 21 in the gap 313 is about at least 0.05mm.In addition, increasing the convex mound 14 of the arc by appropriateness Width can expand the width in the gap 313, to increase the zipper 3 stability mobile on the convex mound 14 of the arc, and increase the heat Fusibleness elastic gum 21 injects the volume of the adjacent slot 321 in 32 inside of buckling component, and the width in the gap 313 Degree.

In fact, the size in the gap 313 when the size on the convex mound 14 of the arc is greater than not by lateral pull is that foundation should The size of zipper 3 is set, i.e., by taking continuous turn type nylon zipper (C-type zipper) as an example, used in No. 3 and No. 5 zippers The convex mound 14 of the arc width about 0.3mm to 1.2mm of the width than the gap 313, and No. 8, No. 10 and No. 5 implicit type zippers About 0.5mm to 3.0mm；Due to the buckling component of Woven slide fastener (S-type) and continuous clip zipper (L-type) with should Support the combination of strap relatively firm, therefore the Woven slide fastener (S- of similar aforementioned continuous turn type nylon zipper size ) and the continuous width comparable on the arc convex mound 14 of clip zipper (L-type zipper) continuous turn type typezipper Nylon zipper is a little bit smaller, such as the width on the convex mound 14 of the arc of S40, S60, L#3 and L#5 about increase 0.3mm to 1.0mm, and S80, S100, L#8 and L#10 are about in 0.3mm to 1.8mm.The 14 increased width of institute of the convex mound of the arc about in 0.3mm to 3.0mm, Than 313 original width about 0.3mm to 3.0mm of the gap, therefore the settable wider gum-injecting port 15 in the convex mound 14 of the arc, to keep away Exempt from the overlapping part that the gum-injecting port 15 is mutually fastened by the buckling component 32 to stop, to reduce the difficulty of encapsulating.

If promote the hot melt elastic gum 21 fills the modes such as pressure or the shape for adjusting the buckling component 32, can ensure that By the hot melt elastic gum 21 in addition to that can fill other than the adjacent slot 321 in 32 inside of buckling component, moreover it is possible to further A part and/or whole inside the inner cavity 324 are injected, to prevent the hot melt elastic gum 21 from taking off from the buckling component 32 It falls, and promotes antiseepage function and durability.

Referring again to Fig. 5, encapsulating film tool and correlation of the zipper in encapsulating are disclosed, which is fastening Under state, which is set to the inner cavity 324, therefore must be pressed using the convex mound 14 of the wider arc and biggish filling, wherein The filling pressure can paste the tightness on the convex mound 14 of the arc via the increase zipper 3 to reach, to fill the hot melt elastic gum 21 A part in the adjacent slot 321 of the buckling component 32, the inner cavity 324 and the gap 313 is filled in, then to this to branch It supports the hot melt elastic gum 21 in the gap 313 of strap 31 and carries out a segmentation process, such as is longitudinally split with cutter progress (being indicated with cut-off rule 314), make the zipper 3 via the encapsulating die 1 encapsulating processing become can division and have antiseepage function One leakage preventing structure of energy.As previously mentioned, using the convex mound 14 of the wider arc other than it the gap 313 can be expanded, also The overlapping part that the related diminution buckling component 32 mutually fastens, this measure are equal between this when eliminating the zipper 3 use in advance Gap 313 will be by the widened width of lateral pull, with the cut-off rule 314 of the hot melt elastic gum 21 reduced in the gap 313 Width, and then promote the antiseepage function of the zipper.

As shown in fig. 6, it shows the 3rd embodiment sectional view of the encapsulating die 1, the present embodiment is compared to first reality Identical label (symbol) shown in example is applied to indicate identical component and provide identical function, due to the present embodiment with it is aforementioned Embodiment shares many shared components, therefore, only that the present embodiment and the Discrepancy Description of the first embodiment is as follows: the arc The height of the front end 141 on convex mound 14 is greater than the height of the rear end 142；And the gum-injecting port 15 connects towards 142 direction of rear end The inclined plane groove 151 that depth tapers off is connect, therefore, as previously mentioned, when the rear guide wheel 42 is in lower position, then the rear end 142 height can control height of the hot melt elastic gum 21 in the gap 313；And guide wheel 42 is in higher position after this When, then the zipper 3 can be separated in the certain point of convex 14 longitudinal length of mound of the arc with the convex mound 14 of the arc so that the zipper 3 from The separation point height for opening the convex mound 14 of the arc determines height of the hot melt elastic gum 21 in the gap 313.Furthermore the inclined-plane The depth of groove 151 is decremented to zero towards the rear end 142, so that the surface of the rear end 142 is had a preset length, for example, at least 1mm is the one brush flat surface 144 of un-grooved, and the smooth out surface 144 is to smooth out the hot melt being located in the gap 313 elasticity The surface of glue 21.

As previously mentioned, that the hot melt elastic gum 21 is directly filled in 32 inside of the buckling component is adjacent for the gum-injecting port 15 The slot 321 and the inner cavity 324 in, and via the hot melt elastic gum 21 of 151 extrusion of inclined plane groove then be used to fill In the gap 313, and in the gap 313 formed strip the hot melt elastic gum 21, so in the gap 313 should The height of hot melt elastic gum 21 is gradually increased from the bottom 322 of the buckling component 32 toward 311 direction of the first face, this Act, which can avoid the hot melt elastic gum 21, is stained with and bonds to first face 311.Since the rear end 142 on the convex mound 14 of the arc has 1mm The smooth out surface 144 of the above length, the smooth out surface 144 is to smooth out the hot melt elastic gum 21 in the gap 313 Surface.Therefore, the height of the rear end 142 and rear 42 height of guide wheel are used to determine the hot melt elastic gum 21 between this Height in gap 313, such as the height of the rear end 142 is 0.15mm, if this to zipper support strap 31 with a thickness of 0.50mm, Height of the hot melt elastic gum 21 in the gap 313 is about at least 0.35mm.

As shown in fig. 7, it shows that the 3rd embodiment of the encapsulating die 1 carries out the sectional view of encapsulating to zipper, due to this The convex mound 14 of arc has the inclined plane groove 151, and the rear end 142 is low compared with the front end 141, which fills in institute It states in the adjacent slot 321 in the inside of buckling component 32 and the gap 313 to support strap 31, guide wheel 42 is in after this When lower position, and the hot melt elastic gum 21 distance first face 311 in the gap 313 is rough is same as the convex mound 14 of the arc 142 height of the rear end.As previously mentioned, being pressed via adjusting convex 14 width of mound of the arc and filling, when 21 note of hot melt elastic gum Enter in the gap 313 and the slot 321 and the inner cavity 324 of buckling component 32, the hot melt elastic gum 21 can be coated continuously The bottom 322 of the buckling component 32 and the inner cavity 324, to form a non-individual body, to promote the antiseepage effect of the zipper Fruit.The hot melt elastic gum 21 of 313 strip of gap is finally subjected to longitudinally split (indicating with cut-off rule 314), makes this Zipper 3 via the encapsulating die 1 encapsulating processing become can division and with antiseepage function leakage preventing structure.

As can be seen from figures 8 and 9, it shows the fourth embodiment schematic diagram of the encapsulating die 1, and utilizes the encapsulating die An antiseepage zipper made of 1.The present embodiment is compared to identical label (symbol) shown in the 3rd embodiment to indicate identical Component and identical function is provided, since the present embodiment shares many shared components with previous embodiment, only will this The Discrepancy Description of embodiment and the 3rd embodiment is as follows: the front end 141 on the convex mound 14 of the arc and the height base of the rear end 142 It is identical in sheet；The gum-injecting port 15 connects an elongate recesses 152 towards 142 direction of rear end, which extends to the arc The rear end 142 on the convex mound 14 of shape fill the hot melt elastic gum 21 not only can at this by opening up for the elongate recesses 152 Gap 313 also further protrudes from first face 311 to support strap 31.

It therefore, can be to the hot melt elastic gum being located in the gap 313 by the different section shape of the long recess 152 21 change its appearance, such as [M shape] or [arc-shaped] etc., this measure can show the hot melt elastic gum 21 this to support strap The appearance in 31 first face 311, and can effectively promote anti-seepage effect.As shown in figure 9, the zipper 3 is continuous turn type drawing Chain (C-type zipper) must arrange in pairs or groups a special slider of zipper fastener to accommodate the hot melt elastic gum 21 of protrusion, such as corresponding The hot melt elastic gum 21 designs the gap road that tail end is extended to from the slider of zipper fastener front end on the path in the slider of zipper fastener, to keep away Exempt from friction caused by the hot melt elastic gum 21 and the slider of zipper fastener, since this belongs to known skill, is not intended to repeat herein.Finally The hot melt elastic gum 21 of strip is carried out longitudinally split (indicating with cut-off rule 314) by the gap 313, passes through the zipper 3 By the encapsulating die 1 encapsulating processing become can division and with antiseepage function leakage preventing structure.

As shown in Figure 10, the 5th embodiment schematic diagram of the encapsulating die 1 is shown, the present embodiment is compared to first reality Identical label (symbol) shown in example is applied to indicate identical component and provide identical function, due to the present embodiment with it is aforementioned Embodiment shares many shared components, therefore, only that the present embodiment and the Discrepancy Description of the first embodiment is as follows: the arc 141 surface of front end on convex mound 14 is equipped with a guide channel 145, the size of the guide channel 145 two column fastening group corresponding with the depth The size and shape of part 32, thus the correcting zipper 3 can stable operation on the transversal line 146 on the convex mound 14 of the arc, to mention The encapsulating quality and efficiency of the high zipper 3.

As shown in figure 11, show that the sixth embodiment schematic diagram of the encapsulating die 1, the present embodiment are real compared to the 5th Identical label (symbol) shown in example is applied to indicate identical component and provide identical function, due to the present embodiment with it is aforementioned Embodiment shares many shared components, therefore, only that the present embodiment and the Discrepancy Description of the 5th embodiment is as follows: the arc The height of the front end 141 on convex mound 14 is greater than the height of the rear end 142, and the convex mound 14 of the arc has a gum-injecting port 15 and one the Two gum-injecting ports 15 '.

Wherein, the gum-injecting port 15 is mainly that the hot melt elastic gum 21 is infused in 32 inside of the buckling component is adjacent The slot 321 and the inner cavity 324, and second gum-injecting port 15 ' connects an inclined plane groove 151 towards 142 direction of rear end, it should The hot melt elastic gum 21 can be injected the gap 313 to support strap 31 by the second gum-injecting port 15 ' and the inclined plane groove 151 It is interior.

The encapsulating die 1 of the present embodiment can link an extruder, to utilize the gum-injecting port 15 and the second gum-injecting port 15 ' one It is same that the hot melt elastic gum 21 is injected separately into the adjacent slot 321 in 32 inside of buckling component, the inner cavity 324 and is somebody's turn to do In gap 313.

Alternatively, as shown in figure 12, the gum-injecting port 15 of the present embodiment and the second gum-injecting port 15 ' can respectively link an extrusion Machine, so as to using the gum-injecting port 15 and the second gum-injecting port 15 ' by two kinds of hot melt elastic gums 21 of different material or color and 21a, the hot melt elastic gum 21 of the gum-injecting port 15 inject the 32 inside phase of the buckling component of a Woven slide fastener 3 without core wire Some in the adjacent slot 321, the inner cavity 324 and the gap 313, and the hot melt bullet of second gum-injecting port 15 ' Property glue 21a then inject in the gap 313, keep two kinds of hot melt elastic gums 21,21a adjacent in 32 inside of buckling component respectively The slot 321 and this to support strap 31 the gap 313 in form different material or color.And rear 42 position of guide wheel is high The low hot melt elastic gum 21a that will affect is in the height in the gap 313.Finally in the gap 313 by the hot melt of strip Elastic gum 21 carries out longitudinally split (indicating with cut-off rule 314), makes the zipper 3 via the encapsulating processing of the encapsulating die 1 For can division and with antiseepage function leakage preventing structure.

In fact, aforementioned hot melt elastic gum 21 is selected from hot melt hot melt adhesive and reactive hot-melt hot melt glue, such as instead Answer type thermoplastic polyurethane (Reactive-TPU), thermoplastic polyurethane (TPU), silica gel (Silicon), Buddhist nun The dragon materials such as (Nylon) or thermoplastic polyester elastomer (TPEE), but not limited to this.

In addition, in addition to it is aforementioned can from the slot 313 carry out encapsulating other than, also can be from the top layer of the buckling component 32 323 surface encapsulating, that is, two-sided encapsulating, so as to promote antiseepage function and increase the diversity of appearance.

Please refer to Figure 13, be encapsulating die shown in Fig. 6 carries out zipper to the sectional view after two-sided encapsulating, that is, It says, to carry out encapsulating from 323 surface of top layer of the zipper 3, still needs to a separation layer to prevent the encapsulating die of high temperature from (not showing Show) the contact buckling component 32, the method for solution is respectively arranged on the surface of the top layer 323 of the two column buckling component 32 One Auxiliary support strap 33 makes to generate an auxiliary gap 331 between the Auxiliary support strap 33.It thus can be respectively from the gap 313 and auxiliary gap 331 that a kind of and/or two kinds of hot melt elastic gums 21 are respectively poured into 32 inside of buckling component is adjacent The slot 321, or further inject into the inner cavity 324, make that respectively there is the length in the gap 313 and the auxiliary gap 331 The hot melt elastic gum 21 of strip.

In fact, the Auxiliary support strap 33 is in addition to that can be isolated the encapsulating die and form the auxiliary gap for encapsulating Outside 331, also simultaneously increase the buckling component 32 and this to support strap 31 binding strength.Therefore, in suture, this is to auxiliary Help the feed length of support strap 33 that can be slightly more than this to support strap 31, to promote the flexibility of the antiseepage zipper.Finally divide The hot melt elastic gum 21 of strip is not subjected to longitudinally split (indicating with cut-off rule 314) in the gap 313 and 331, is made The zipper 3 via the encapsulating die 1 encapsulating processing become can division and with antiseepage function leakage preventing structure.
