According to the invention, the structure of the shoulder of the paste extrusion pipe is changed, so that the shoulder of the paste extrusion pipe does not generate the dead space with the pipe body in the extrusion process, the paste can be thoroughly used, the waste is avoided, and the product use experience of a user is greatly improved.
Description
Technical field
The present invention relates to a kind of structure of easily squeezing type paste or liquid extruding pipe, structure and the production technology of the pipe shoulder that makes the extruding pipe that the paste that holds in paste or liquid extruding pipe or liquid is utilized more fully is specifically provided.Tradition paste extruding pipe, because its pipe shoulder maintains original shape for the architectural feature of uniform wall thickness makes pipe shoulder in the time extruding medicament, is difficult to distortion.When in pipe, paste or liquid use remainder, because pipe shoulder is difficult to distortion, the residue paste retaining in pipe shoulder and body junction or liquid, in being difficult to the pipe shoulder dead angle of distortion, can not be extruded completely, cause the waste of paste in pipe.The present invention, by changing the structure of paste extruding pipe pipe shoulder, make paste extruding pipe pipe shoulder not produce dead angle with body in crumpling process, thereby paste can be used by more thorough, and avoids causing waste, and user's product experience is also improved significantly.
Background technology
Many paste products use and can pack by squeezing tube in the market, as toothpaste, and cosmetics, food, medicine etc.This series products majority packs into pipe from the afterbody of pipe, shuts the pipe shoulder mouth hole of being takeed on by top pipe after afterbody and extrudes.Existing paste or liquid extruding pipe are noted shoulder as plastics such as the multiplex HDPE of toothpaste ointment and are made on plastic-aluminum or plastic hose, or make with metal integral die casting.The pipe of making shoulder outline by existing technique is all circular or oval, and pipe shouldered wall is thick is the structure of uniform wall thickness, and portioned product pipe shoulder has the reinforced rib stretching out along flexible pipe direction.This architectural feature and material behavior make pipe shoulder in the time being squeezed, maintain original shape, are difficult to distortion.When in pipe, paste or liquid use remainder, because the circular contour with body junction of pipe shoulder is difficult to be subject to squeeze distortion, pipe shoulder and body form dead angle, the residue paste retaining in pipe shoulder and body junction or liquid are pressed against the pipe shoulder dead angle that is difficult to distortion, can not be extruded and be utilized, thereby cause the waste of paste.The experience that user uses is also very not humane.
Therefore be necessary to provide a kind of structure of Novel extrusion pipe, make to manage interior paste and utilized and improve user's experience completely.
Summary of the invention
The object of this invention is to provide a kind of novel structure of easily squeezing formula paste liquid extruding pipe.Make in the process of extruding pipe paste or liquid in user's extruding pipe, the pipe of extruding pipe is takeed on the in-plane distortion that also can be crushed along body, making to manage the shape of shoulder after being squeezed can become the slice-shaped flattening after extruding along with body, and the interior paste of extruding pipe or liquid can be more easily extruded.Do not cause waste, and improve the experience of user while using.
For achieving the above object, the invention provides following technical approach and realize the architectural feature of above-mentioned extruding pipe.
Extruding pipe comprises body and pipe shoulder.Body one end connection pipe shoulder, the body other end seals packing into after paste or liquid.Pipe shoulder is made up of pipe shoulder mouth and pipe shoulder body, has pipe shoulder mouth hole on pipe shoulder mouth, and the paste of extruding pipe inside or liquid are extruded by managing shoulder mouth hole.Body in user's crumpling process, produced extruding pipe flatten plane, extruding pipe is converted into thin slice flat with respect to this plane, body flatten line be body in use body be crushed form a pair of straight line.
The wall thickness that pipe shoulder flattens plane both sides at extruding pipe is less than pipe shoulder by flexible pipe axle center and flattens the thickness of plane both sides perpendicular to extruding pipe.Below be called pipe shoulder thin-wall regions by managing shoulder in the thinner region of wall thickness of extruding pipe flattening plane both sides, will and be called pipe perpendicular to the thicker region of wall thickness of extruding pipe flattening plane both sides by flexible pipe axle center and take on thin-wall regions.Reducing pipe shoulder is in order to impel pipe shoulder to flatten web direction distortion to body at the wall thickness of extruding pipe flattening plane both sides.
Pipe shoulder thin-wall regions is the 45%-85% of pipe shoulder thick wall area thickness, can ensure the distortion of pipe shoulder and resilience, ensure that again pipe shoulder thickness can seal for example toothpaste volatile substances in extruding pipe; between the thick and thick wall of thin-walled, have the variation in thickness of gradual change excessive, ensure that the pipe shoulder of injection mo(u)lding does not have shrink.
Between pipe shoulder body and pipe shoulder mouth, have the excessive step of pipe shoulder, the wall thickness of the excessive step of pipe shoulder is less than pipe shoulder mouth wall thickness, and is less than the thickness of pipe shoulder thick wall area.The thickness of the excessive step of pipe shoulder approximates pipe shoulder and flattens the wall thickness of plane both sides at extruding pipe.The excessive step of pipe shoulder is the core of body distortion, owing to managing the excessive step of shoulder than the wall thickness of the pipe shoulder body of its both sides or pipe shoulder mouth, so can be out of shape along the shape of the excessive step of pipe shoulder when whole pipe is takeed on deformation in compression.
The excessive step profile of pipe shoulder is shaped as camber line or camber line and straight line and jointly forms.If takeing on excessive step profile at the pipe of pipe shoulder body thick wall area is straight line, pipe shoulder deformation resilience weak effect, if the excessive step profile of pipe shoulder is positive circle herein, extruded tube shoulder makes the feel of pipe shoulder distortion just poor, so the length that decision design example is the excessive step profile of pipe shoulder flattens in-plane at extruding pipe was greater than flexible pipe axle center and perpendicular to the be crushed length of in-plane of extruding pipe, and whole pipe is takeed on excessive step and is made up of circular arc, sees the example providing after this specification sheets.The excessive step profile of pipe shoulder is upper and lower symmetrical and symmetrical.Be beneficial to whole body and be deformed into the shape of flattening rear thin slice.
Pipe shoulder thin-wall regions approximates the width of the excessive step of pipe shoulder at the width at pipe shoulder excessive step place, two thin-walled lines that main pipe shoulder is out of shape are formed with the excessive step of pipe shoulder, article two, lines are distributed in extruding pipe extruding flat horizontal surface both sides, and these two lines main pipe shoulders are faced folding to flattened.Pipe shoulder thin-wall regions stretches out from the excessive step of pipe shoulder, and it is large that width becomes, until pipe shoulder edge, shape a fan shape.Flatten pipe shoulder thick wall area in plane direction projection direction at extruding pipe and accounted for more than 50% area or the profile of whole pipe shoulder, and accounting for more than 50% area or the profile of whole pipe shoulder by extruded tube axle center and perpendicular to flattening plane direction projection pipe shoulder thin-wall regions.
Such architectural feature is through the optimized distressed structure that draws of experiment, on the pipe shoulder thin-wall regions of extruding pipe extruding flat horizontal surface both sides, is exactly the distortion of pipe shoulder and the concentrated region of stress, makes that pipe shoulder is smooth to be pushed flat and have certain rebound characteristics.
The function of pipe shoulder thick wall area is the main region that user's hand squeezes pipe shoulder, and user, in the time pushing herein, ensures that pipe shoulder flattens the leading distortion of pipe shoulder thin-wall regions of plane both sides at extruded tube, thereby forms the flattening mode of guiding in advance.
If whole pipe shoulder body is the wall thickness of pipe shoulder thin-wall regions, the effect that also can realize distortion of whole pipe shoulder, only effect is good not.Have following shortcoming: pipe shoulder integral rigidity variation, pipe shoulder will directly be out of shape in the position of middle hand.Due to the attenuation again of pipe shoulder thickness, pipe shoulder odor seal variation.Although can realize the flat object of extruding, it not optimized scheme yet.
Pipe shoulder has stretched out pipe shoulder wall extension in body direction, pipe shoulder wall extension after pipe shoulder is combined with body inside body, pipe shoulder wall extension both sides are greater than it in the length of flattening line place near body and flatten the length in the middle of plane projection at extruding pipe, wall extension is preferably arc in the projection of shape of extruding pipe extruding flat horizontal surface, arc is recessed in body one side, namely arc curvature center is in body one side, and wall extension is jagged at body flattening line place, to dredge body distortion.The design of pipe shoulder wall extension is also that while being extruded into sheet type due to pipe shoulder on the other hand, flexible pipe can be wrinkling in order to promote the distortion of pipe shoulder, and pipe shoulder wall extension can become the straight line after extruding by the arc before extruding, and the shape of pipe shoulder wall extension can avoid flexible pipe wrinkling.It is jagged that pipe is takeed on the wall extension outermost end both sides phase position crossing with extruding pipe extruding flat horizontal surface, the flexible pipe distortion that can assist relevant position.It is slightly thin that the wall ratio pipe of pipe shoulder wall extension is takeed on thin-wall regions wall thickness, and pipe shoulder wall extension thickness is takeed on wall extension and flattened line junction breach size or have or not and can be out of shape and bounce situations by adjustable pipe shoulder with pipe.
In the time that pipe shoulder needs better rebound resilience, increase pipe shoulder wall extension thickness; In the time that pipe shoulder needs better extrudability, reduce pipe shoulder wall extension thickness.In the time that pipe shoulder needs better rebound resilience, reduce or remove above-mentioned breach, in the time that pipe shoulder needs better extrudability, strengthen this breach.
Body is attached to the profile on pipe shoulder, and the projection on extruding pipe extruding flat horizontal surface is curve arc, and arc is recessed to the side near pipe shoulder, and arc curvature center is in the side near pipe shoulder.Such design is beneficial to the aesthetic property of the whole extruding pipe after pipe shoulder flattens.
Learn through experiment, above-mentioned arc both sides are greater than 10% of approximately whole hose diameter than the middle size exceeding and body and pipe need to be takeed on to binding end when above and cut out the arc similar to Guan Jian projected outline in the projected outline of extruding pipe flattening in-plane by rectangle.This size more conference make pipe shoulder become pipe after slice-shaped to take on the outward appearance of being combined with body more attractive in appearance.
If do not carry out above-mentioned action, it is too much higher than pipe shoulder profile that body can be extruded direction at flexible pipe, can make body be pressed onto when pipe is takeed on above and fold.
And above-mentioned arc both sides than the middle size exceeding be less than or equal to approximately whole hose diameter 10% time, do not need body to cut out the arc similar to Guan Jian projected outline to the profile that pipe shoulder binding end flattens in-plane at extruding pipe by rectangle, keep the projected outline of body rectangle can in the time that body is pressed onto on pipe shoulder, not fold yet.
The manufacture craft that cuts out similar arc body is to cut out flexible pipe circular arc with hobboing cutter on hose making machine, because the body on hose making machine is continuous, one end cuts out indent arc, and the arc that can product protrude follow-up connection need to add one hobboing cutter and cut the arc of protrusion is cut flat.Plastic-aluminum sheet material is hot pressed into the seam of body and hobboing cutter and cuts out the direction that cambered surface arc is high and approach, and flattens line with body and approaches, and makes seam in the position that approaches body and flatten line, does not affect overall appearance.
Another method for making is the radian of protrusion to be cut flatly on flexible tube sealing machine, and the arc that this outer flexible tube afterbody protrudes does not affect the appearance and uses function, can not cut yet.
Pipe shoulder profile flattens at extruding pipe the length that the length of in-plane was greater than flexible pipe axle center and flattened in-plane perpendicular to extruding pipe, and pipe shoulder contour shape is that camber line or camber line and straight line form jointly.Preferred embodiment, for to be made up of camber line, is shown in the example providing after this specification sheets.Projected outline is also upper and lower symmetrical and symmetrical, is beneficial to whole body and is deformed into the shape of flattening rear thin slice.It is same point that the line point crossing with pipe shoulder flattened with body in the summit, both sides of pipe shoulder thin-wall regions profile.
When splendid attire paste or liquid are extruded in pipe at body, be less than pipe shoulder main body because pipe shoulder is takeed on excessive step wall thickness with the pipe between pipe shoulder mouth, and coordinate the curve shape of the excessive step of pipe shoulder, then due to pipe shoulder thin-wall regions and manage and take on the crossing profile of heavy wall; Extruding pipe pipe shoulder thin-wall regions approximates the width of the excessive step of pipe shoulder at the width at pipe shoulder excessive step place, two thin-walled lines that main pipe shoulder is out of shape are formed with the excessive step of pipe shoulder, article two, lines are distributed in extruding pipe and flatten plane both sides, and these two lines main pipe shoulders are faced folding to flattened.Also have the pipe of cooperation shoulder wall extension to coordinate the distortion of pipe shoulder.
Integral structure makes pipe shoulder have certain elasticity, and in the time that user uses, pipe shoulder is along with body is out of shape together, has ensured in pipe that splendid attire paste or liquid are extruded completely, ensured again extruding pipe extrude feel and extrude after whole attractive in appearance.
Extruding pipe pipe shoulder material is thermoplastic elastomer, thermoplastic plastic or metal, and due to the factor of the aspects such as cost technique, the materials such as preferred present widely used PE or PP.Extruding pipe body is made up of plastic-aluminum or plastics, and one end connects with pipe shoulder seal, and body is that injection moulding is connected or is hot bonding with pipe shoulder connecting mode.Metal extruding pipe is formed by integral die-cast.
The present invention is preferably applicable to dentifrice tube, Medical ointment tube, cosmetics, the pasty masses such as food can extruding pipe.But be not limited to these, other pipe agent package tube is applicable equally.
By reading content disclosed herein, for those skilled in the art, feature of the present invention, advantage can be apparent.

Referring to Fig. 3 .1 to Fig. 3 .3, in the use procedure of the interior paste pipe of body 300, the state of paste extruding pipe when different residue dosage paste.The state that paste will be finished in body shown in Fig. 3 .3, because pipe shoulder 200 is out of shape along with body 300 flattens, makes pipe shoulder become flat sheet type, has become state shown in Fig. 3 .3.In pipe, thereby paste or the liquid of all splendid attires can successfully be extruded and cut the waste, and improve user's experience.In crumpling process, body thin slice flattens line 302 and extends to gradually pipe shoulder 200 from body 300 bottoms, forms hose body and flattens line and pipe shoulder joint 303 (as shown in Fig. 3 .3).
Referring to Fig. 4 .1-4.4, provide the three-view diagram of pipe shoulder 200.The projection that Fig. 4 .1 is perpendicular to extruding pipe and extrudes direction, the system of axes namely defining in Fig. 1 is perpendicular to the direction of Z axis.As shown in Fig. 4 .1 and Fig. 4 .4 pipe shoulder extrude direction at extruding pipe, the projected outline of the Z-direction pipe shoulder namely defining in Fig. 1.L is the entirety of the pipe shoulder outline line crossing with body.S1 is the pipe shoulder thick region of body upper wall, and S2 is the region of pipe shoulder body upper wall thickness, and L1 is the profile of the position part of pipe shoulder thick wall area, and L2 is the profile of pipe shoulder thin-wall regions position.
Referring to Fig. 6, show that the thickness of pipe shoulder thin-wall regions S2 is 0.8mm, the thickness of pipe shoulder thick wall area S1 is 1.2mm.The wall thickness of the position that S1 is connected with S2 gradually changes excessive.The size of this example had both ensured that pipe shoulder thickness can seal for example toothpaste volatile substances in extruding pipe, and thin wall thickness regions and thick wall are interregional has the variation in thickness of gradual change excessive, ensured that again the pipe shoulder of injection mo(u)lding does not have shrink.Pipe shoulder thick wall area S1 can be positioned at outside face or the inside face of pipe shoulder, in this example, pipe shoulder thick wall area S1 is placed in to inside face, ensures that pipe shoulder smooth in appearance is continuous.
Referring to Fig. 4 .1,4.2 and Fig. 5 .1,6.1, show pipe shoulder 200 by pipe shoulder mouth 210 and pipe shoulder body 230 and formed, between them, have the excessive step 220 of pipe shoulder, pipe shoulder wall extension 240 is arranged at pipe shoulder body 230 bottoms.The wall thickness of takeing on thick wall area S1 or pipe shoulder mouth 210 referring to the wall ratio pipe of Fig. 6 .2, Fig. 6 .3 and the excessive step 220 of Fig. 6 .4 pipe shoulder, excessive step 220 wall thickness of pipe shoulder approximate the wall thickness of managing shoulder thin-wall regions S2.Namely approximate pipe shoulder flattens plane both sides wall thickness at extruding pipe.As shown in partial enlarged drawing 6.4, in this example, the thickness of excessive step 220 both directions of pipe shoulder is 0.8mm.And pipe shoulder mouth mean thickness is 1.5mm, the thickness of pipe shoulder thick wall region S1 is 1.2mm.
The pipe providing referring to Fig. 4 .2 Fig. 4 .4 and Fig. 5 .2 is takeed on excessive step 220 structures, the excessive step 220 of pipe shoulder is cores of body distortion, because the excessive step of pipe shoulder is than the wall thickness of the pipe shoulder body of its both sides or pipe shoulder mouth, so can be along the shape distortion of the excessive step of pipe shoulder when whole pipe shoulder deformation in compression, in this example, the contour shape of the excessive step of pipe shoulder is that camber line connects to form, and is the advantageous applications example of claim scope.See shown in Fig. 4 .4, if the excessive step 220 of pipe shoulder is straight lines with pipe shoulder S1 intersection, thick wall region 2201, deformation resilience weak effect, 2201 places are if pure circle, and the feel of extruded tube shoulder is just poor, so as shown in Fig. 4 .4, the excessive step profile of pipe shoulder is designed to the length of extruding pipe flattening plane, namely X-direction size, the length that was greater than flexible pipe axle center and flattened in-plane perpendicular to extruding pipe, namely Y direction size.And entirety is made up of circular arc, the excessive step profile of pipe shoulder is upper and lower symmetrical and symmetrical.Be beneficial to whole body and be deformed into the shape of flattening rear thin slice.
Referring to Fig. 4 .4, the width W 1 at pipe shoulder excessive step place of pipe shoulder thin-wall regions S2 approximates the width W 2 of the excessive step of pipe shoulder, and pipe shoulder thin-wall regions S2 stretches out from the excessive step of pipe shoulder, and it is large that width becomes, until pipe shoulder edge, shape a similar fan shape.Take on excessive step with pipe and formed two thin-walled lines X1 and X2 that main pipes shoulder is out of shape, two lines are distributed in extruding pipe and flatten plane both sides, and these two lines main pipe shoulders are faced folding to extruding pipe flattened.Can see from Fig. 6 .2, flatten in plane direction projection direction at extruding pipe, namely in Y direction, pipe shoulder thick wall area S1 and profile L1 region have accounted for more than 50% area or the profile of whole pipe shoulder, can see from Fig. 6 .3, flattening in-plane by extruded tube axle center and perpendicular to extruding pipe, namely in X-direction, projection cathode-ray tube shoulder thin-wall regions S2 and profile L2 have accounted for more than 50% area or the profile of whole pipe shoulder.
To flatten the pipe shoulder thin-wall regions of plane both sides be exactly the distortion of pipe shoulder and the concentrated region of stress to extruding pipe like this, makes pipe shoulder push smoothly flat and have certain rebound characteristics.
Referring to Fig. 4 .2 Fig. 4 .3 Fig. 5 .1 Fig. 5 .2, under pipe shoulder body, be that the position that body combines stretched out pipe shoulder wall extension 240, as shown in Fig. 4 .3, pipe shoulder wall extension 240 is greater than its intermediate length in the Z-direction length of pipe shoulder both sides, in this example, pipe shoulder wall extension is that the preferable shape within the scope of claim is arc, arc is recessed in body one side, and namely arc curvature center is in body one side, instead of in pipe shoulder direction.As shown in Fig. 4 .2, it is jagged 2402 that pipe shoulder wall extension and body flatten line junction, dredges pipe shoulder and be out of shape.The wall ratio pipe shoulder thin-wall regions wall thickness of pipe shoulder wall extension 240 is slightly thin, and in this example, the wall thickness of pipe shoulder wall extension 240 is 0.5mm.
The design of pipe shoulder wall extension is also for promoting the distortion of pipe shoulder, while being extruded into sheet type due to pipe shoulder on the one hand, body can be wrinkling with pipe shoulder joint, can be become as the near linear 2401` after Fig. 7 .1 extruding by the arc before extruding referring to Fig. 4 .3 pipe shoulder wall extension base 2401, the shape of pipe shoulder wall extension can avoid body wrinkling after extruding pipe flattens with pipe shoulder junction.Pipe shoulder wall extension thickness is takeed on wall extension and is flattened line junction breach size or have or not and can be out of shape and bounce situations by adjustable pipe shoulder with pipe.
In the time that pipe shoulder needs better rebound resilience, increase pipe shoulder wall extension thickness; In the time that pipe shoulder needs better extrudability, reduce pipe shoulder wall extension thickness.In the time that pipe shoulder needs better rebound resilience, reduce or remove above-mentioned breach 2401, in the time that pipe shoulder needs better extrudability, strengthen this breach 2401.
Referring to Fig. 4 .3 pipe shoulder profile crossing with body, the projection of flattening in plane at extruding pipe is curve arc, and arc curvature center is in the side near pipe shoulder.Learn through experiment, above-mentioned arc both sides are greater than 10% of approximately whole hose diameter than the middle size H exceeding and body and pipe need to be takeed on to binding end when above and cut out the arc similar to Guan Jian projected outline in the body projected outline of extruding pipe flattening in-plane by rectangle.If do not carry out above-mentioned action, it is too much higher than pipe shoulder profile that body can be extruded direction at flexible pipe, can make body be pressed onto when pipe is takeed on above and fold, and affects whole extruding pipe attractive in appearance.
And above-mentioned arc both sides than the middle size exceeding be less than or equal to approximately whole hose diameter 10% time, do not need body to cut out the arc similar to Guan Jian projected outline to the body projected outline that pipe shoulder binding end flattens in-plane at extruding pipe by rectangle, keep the projected outline of body rectangle can in the time that body is pressed onto on pipe shoulder, not fold yet.
Fig. 4 .1 and Fig. 4 .4 have shown that in this application example, pipe shoulder profile is being that directions X length is greater than Y-direction length perpendicular to the outline projection L that extrudes direction.In Y-direction, length is little makes whole pipe shoulder more easily squeeze flat.This application example pipe shoulder is made up of continuous arc.
Fig. 4 .1 illustrated, the profile L2 outermost summit 202 of pipe shoulder is also that circular arc L2 mid point flattens line 302 with body thin slice and intersects at the shoulder of body pipe shown in Fig. 3 .3 flattening joint 303.Pipe shoulder outline left and right is along Y plane symmetry, up and down along X plane symmetry, profile arc-shaped edges outermost end points 202, also just flatten line joint 303 with body thin slice shown in Fig. 3 .3 and overlap on symmetrical plane X, the mid point 201 of the silhouette edge L1 at the thick place of pipe shouldered wall is outermost point of the pipe shoulder profile in symmetrical plane Y-direction.Tangent connection between pipe shoulder thick wall silhouette edge L1 and the thick silhouette edge L2 of pipe shoulder thin-walled.
Take on the section drawing after squeezed flattening referring to Fig. 7 pipe, there is variation in pipe shoulder profile after flattening.Because the wall ratio periphery of the excessive step 220 of pipe shoulder is thin, add thin-walled lines X1 and the X2 of main pipe shoulder distortion described in Fig. 4 .4 above, and the leading distortion of pipe shoulder thin-wall regions S2.
Again referring to Fig. 8, section drawing after the extruding of pipe shoulder, dotted line is the pipe shoulder profile after flattening, in pipe shoulder 200 extrusion processes, pipe shoulder thick wall area S1 silhouette edge L1 position is because of the doubling of pipe shoulder, and when extruded tube shoulder, L1 and L2 position change, move to L1` and L2` position, pipe shoulder thick wall area S1 and profile L1 are because the wall thickness shape invariance before the large maintenance extruding of its wall thickness is that it is close that pipe is takeed on two profile L1 limits of thick wall region S1 along the inside doubling of the pipe excessive step 220 of shoulder.Pipe shoulder thin-wall regions S2 and profile L2 are because thinner wall thickness is out of shape to both sides, and by the excessive step 220 of pipe shoulder and pipe shoulder thin-walled S2 region combined action, pipe shoulder profile becomes flat.Make shape that pipe shoulder 200 can flatten along with body 300 by becoming slice-shaped, i.e. 10 to 10` alteration of form in shape in Fig. 9 and Fig. 1.
Pipe shoulder wall extension 240 is become the 240` of Fig. 7 .1 by the arc shown in Fig. 4 .3.The base 2401 of pipe shoulder wall extension 240 is become the 2401` of Fig. 7 .1 line-like by the arc shown in Fig. 4 .3.Attractive in appearance from body internal support pipe body.Form the rear effect of extruding as Fig. 9 demonstration.
Referring to Figure 10, pipe shoulder arc both sides are greater than 10% of approximately whole hose diameter than the middle size H exceeding and body and pipe need to be takeed on to binding end when above and cut out arc as similar to Guan Jian projected outline with Figure 10 .4 in Figure 10 .2, Figure 10 .3 at the profile of extruding pipe flattening in-plane by rectangle.
Referring to Figure 11, illustrate that it is to cut out flexible pipe circular arc with hobboing cutter 530 on hose making machine 540 that there are body 500 manufacture crafts of arc one end, because sheet material 520 is continuous, follow-up flexible pipe 510 has formed the arc protruding.This additional one hobboing cutter 530` cuts away the protrusion arc 505 that continuous flexible pipe produces.Plastic-aluminum sheet material is hot pressed into the seam of body and hobboing cutter and cuts out the direction that cambered surface arc is high and approach, and flattens line with body and approaches, and makes seam approaching the position of flattening line, does not affect overall appearance.
Can the radian of protrusion be cut flatly on flexible tube sealing machine, as shown in figure 12, the outstanding arc of this outer flexible tube afterbody does not affect the appearance and uses function, can not cut yet yet.
The pipe that the pipe shoulder average wall thickness that whole pipe shoulder body is thinner also can be realized within the scope of the claims in the present invention is takeed on the lamelliform function that is deformed into flattening with body.If whole pipe shoulder body is the wall thickness 0.8mm of pipe shoulder thin-wall regions S1, the effect that also can realize distortion of whole pipe shoulder, only effect is good not.Have following shortcoming: pipe shoulder integral rigidity variation, the distortion of pipe shoulder will be directly out of shape in the position of middle hand.Due to the attenuation of pipe shoulder integral thickness, pipe shoulder odor seal variation.Although can realize the flat object of extruding, it not optimized scheme yet.Below the application example in Figure 13 has illustrated this application mode.
Referring to Figure 13, provide the second application example 600 within claim scope.In this example, the material of pipe shoulder is for remaining HDPE, high density polyethylene (HDPE).The overall average wall thickness of pipe shoulder is 0.8mm.Because pipe shouldered wall is thick little, easily distortion.Pipe shoulder body entirety is all pipe shoulder thin-wall regions S2.Other architectural feature of this application example is identical as the example in picture group 1-9, and the process of distortion and principle are also identical with the example explanation in Fig. 1-9 on the same group.Be that whole application example is not as the application example optimization in picture group 1-9.
Provide in specification sheets the two kinds application examples in claim scope.In comparison diagram 14.1-14.3, do not use the common paste extruding pipe 900 of structure of the present invention, the cream shoulder shape of common paste extruding pipe mostly is circular, in common paste extruding pipe, paste uses and approaches while being finished, because there is no auxiliary deformation groove on common paste extruding pipe pipe shoulder, pipe shoulder can not flatten line Direction distortion along body thin slice.Common paste extruding pipe does not have the straight flange of pair of parallel yet, even if force pipe shoulder along flattening line doubling, pipe shoulder limit and the body of circular arc still can form dead angle 901 as shown in figure 13.Part remains paste and retains and put 901 places, dead angle, can not be extruded.
Pipe shoulder material in this example preferably uses HDPE, and the application example within the scope of claim can be selected thermoplastic plastic, thermoplastic elastomer or metal, but is not limited to above material.The material of this example body preferably uses plastic-aluminum combined sheet material or pure plastic hose, and the application example within the scope of claim can be selected or metal, thermoplastic elastomer, but be not limited to above material.This example body is injection mo(u)lding pipe shoulder with the optimal way of pipe shoulder combination, within the scope of claim should be with comprising compression moulding, techniques such as the bonding pipe shoulder of hot blast high frequency, but be not limited to above-mentioned technique.
In specification sheets, described the preferred embodiments of the present invention, but the present invention is not limited to this.For those skilled in the art, in claim limited range, can there is multiple amendment, be equal to and mutation.
