Description
Technical field
The present invention relates to a kind of sebific duct, the high roller sebific duct specifically used on a kind of computer flat knitting machine.The invention still further relates to the manufacture method of above-mentioned sebific duct.
Background technology
The effect of roller is for batching the fabric of downward braiding, and high roller fast development in recent years in the flat machine industry is got up.As shown in Figure 1, high roller mainly is comprised of the roller sebific duct 4 of headscrew 3, cushion block 2, roller bearing 1, two ends main spindle box body 5, the involutory rotation in both sides and gear etc.The use producer that computer flat knitting machine is general produces uninterruptedly in 24 hours, and as shown in Figure 2, before and after high roller, sebific duct is across constantly engagement friction rotation of braided fabric 6.
The problems such as the roller sebific duct 4 used on computer flat knitting machine at present will produce in use for some time and skid, crack, service life is shorter, needs often will change.Changing roller sebific duct 4 is the work of a burdensome, need to shut down during replacing and stop producing, and the price of a set of roller sebific duct is also more expensive.
The inwall of high roller sebific duct is to adopt the line thread type, and the screw flight interlock, and the male and fomale(M&F) contact increases screw rod when rotating and the frictional force of sebific duct, makes sebific duct drive roller bearing and rotates together.Batch the fabric just knit out.
Therefore, the requirement of roller sebific duct is harsher, can not be too flexible and rigid, and certain intensity and tube wall outwards can extend in right amount the elasticity of expansion, just can use with durable.
Fig. 3 is existing knitting Computerized flat knitting machine roller sebific duct 4 commonly used, in sebific duct, without the fiber gummed, is not durable.Such sebific duct is 201020188604.0 disclosed as the patent No., and tough of this sebific duct external tooth colyliform, tough ditch be alternative arrangement repeatedly, and the application of the existing many decades of this structure, be impractical in high roller.The cloth clamping degree is batched in this structural adjustment, or is exactly too loose, can not batch; Be exactly too tight, stiff action.The cropping of Computerized flat knitting machine batches function, and it is will be according to the Fabric Design of ever-changing colored type, and the speed of the cropping speed drawn game clan cloth of generation surpasses to fall to getting pulling force speed sebific duct and automatically produce and skid.It is this that the sebific duct of tough is arranged is to realize.
Fig. 4,5 is existing sebific duct industry way commonly used (not the roller sebific duct adopts structure), woven fabric and yarn glued construction, but the sebific duct of this structure stretches out, the elasticity expanded is few, not naturally, be close to fabric when roller batches rotation, as be applied on the roller sebific duct effect of batching that can't reach desirable.And the rubber tube inner wall of high roller has screw thread, when making, because the expansion elasticity that stretches out is few, be unfavorable for the demoulding.
The high roller sebific duct is different from the sebific duct main feature of other industry: it is that a pair of front and back coordinate the combination sebific duct inwardly rotated, in the crack of front and back sebific duct, the braided fabric cropping is batched in engagement, the sebific duct desired strength is high, and pliability is good, the rich elasticity that stretches out and expand.
The utility model patent that the patent No. is 200620080581.5 discloses a kind of braided net reinforced plastic tube, the braided net of sebific duct inside is located between inner and outer pipes, between mesh, with the connected a kind of single layer structure of latch closure, mesh diameter is the 2-4 millimeter, and netting twine used is 2-5 road twine.Braided net between inner and outer pipes is a kind of enhancing net, and between mesh, latch closure is connected, and the ring latch closure is lived, and improves the compressive resistance of pipe, and it is mainly used in fluid and carries, and is not suitable for the high roller sebific duct.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of high roller sebific duct, this sebific duct has elasticity and pliability preferably, makes sebific duct more high resilience when batching braided fabric, makes fabric even tractive downwards pliable and toughly, improve fabric quality, delay sebific duct service life.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
A kind of high roller sebific duct, comprise the tissue layer be embedded between sebific duct outer wall and inwall, the weft-knitted fabric that described tissue layer is three-dimensional institutional framework.
The weft-knitted fabric of described three-dimensional institutional framework is single face braided structure, ribbed knitting structure or ingot braided structure.
The material of described sebific duct is rubber or polyurethane.
The latitude direction of the weft-knitted fabric of described three-dimensional institutional framework is identical with the circumferencial direction of sebific duct.
Because the weft-knitted fabric of three-dimensional institutional framework all can stretch on either direction, so the high roller sebific duct has elasticity preferably, and such elasticity has been guaranteed that high roller sebific duct surface long term is used and can not ftractureed, improved the service life of sebific duct.
And, the elasticity of above-mentioned high roller sebific duct is the elasticity that is different from the disclosed braided net reinforced plastic tube of utility model patent that the patent No. is 200620080581.5, because the elasticity of braided net reinforced plastic tube is whole elasticity, the elasticity that inside and outside wall of braided net reinforced plastic tube jointly stretches and produces.
Elasticity of the present invention not only comprises the sebific duct inside and outside wall flexible elasticity produced jointly, but also comprises the elasticity on sebific duct surface, the i.e. elasticity of the flexible generation of sebific duct outer wall on inwall.Thereby sebific duct rotates in opposite directions the fabric in the middle of it is batched downwards before and after high roller, and this elasticity plays vital effect for batching fabric, can be according to the thickness of fabric the distance between suitable self-regulation two sebific duct surfaces.
Three-dimensional institutional framework weft-knitted fabric makes sebific duct integral body more pliable and tougher in sebific duct inside, while rotating on high roller for a long time, roller sebific duct and quilt are batched fabric and can not skidded in controlling weight range, batch cropping pliable and toughly, make fabric even tractive downwards, improve fabric quality.
Friction pulling force, the speed of batching fabric during high roller work are constant, but in actual braiding process, the variation required due to variation and the weaving of the institutional framework of braided fabric, need the roller sebific duct to keep certain constant force when batching fabric, when coiling speed is greater than fabric cropping speed, high elasticity of the present invention, flexible sebific duct can skid on braided fabric, thereby can automatically adjust, for example: can solve some highly difficult three-dimensional shirt rim braidings, without sewing up one-time formed knitting, can wear the sweater craft woven, embody the good characteristics of this sebific duct.
High roller is in the work coiling process, and the static produced between sebific duct and fabric often makes yarn sticky suction the in fabric both sides be wrapped in impact generation on the roller sebific duct.Mix the weft-knitted fabric of three-dimensional institutional framework in sebific duct, make the structure of sebific duct integral body that very large variation occur, due to the increase of stereo fabric volume, the material composition that forms sebific duct greatly reduces, make the structural constituent of sebific duct play variation, reduce the generation of static.
Research shows, humidity is conducive to reduce the generation of static.In sebific duct, a large amount of fabrics can absorb moisture in large quantities, makes sebific duct keep certain humidity, and static will be difficult to produce, and reduces even to stop the both sides yarn and inhales sticky spiral rubber hose because of static.
Inside of the present invention has the roller sebific duct of three-dimensional institutional framework weft-knitted fabric, and existing sebific duct has more advantage, and as high elasticity and high-flexibility, these advantages are that three-dimensional institutional framework weft-knitted fabric brings.After the long-term use of sebific duct, phenomenon of rupture appears in its inside sometimes, and main manifestations is mutually to break away between the sebific duct inside and outside wall.According to normal thinking analysis, roller sebific duct inside has the weft-knitted fabric of three-dimensional institutional framework to connect internal and external walls the problem mutually broken away between the sebific duct inside and outside wall should not occur.
Through a large amount of experimental analyses, we find that reason is the weft-knitted fabric of the three-dimensional institutional framework of roller sebific duct inside.The weft-knitted fabric of the three-dimensional institutional framework of roller sebific duct inside has increased the intensity of sebific duct, has greatly improved elasticity and the pliability of sebific duct.High elasticity and high tenacity are that the structural deformation by the weft-knitted fabric of three-dimensional institutional framework brings, the weft-knitted fabric of thirty years of age soma's structure merges with the roller hose material during fabrication, the long-time larger structural deformation of the weft-knitted fabric of three-dimensional institutional framework, certainly will cause the weft-knitted fabric of three-dimensional institutional framework and the material of roller sebific duct to break away from, finally cause the fracture of sebific duct inside, finally show as between the sebific duct inside and outside wall and mutually break away from, cause quality problems.
For addressing the above problem, the present invention first forms banding by braiding after single fiber yarn or the merging of plurality of fibers yarn, and then is woven into the weft-knitted fabric of three-dimensional institutional framework by banding.This scheme has further increased elasticity, the pliability of roller sebific duct on the one hand; Most important is the increasing that elasticity, flexible raising not are based upon the weft-knitted fabric deformation of three-dimensional institutional framework on the other hand, when sebific duct produces elastic deformation, the banding itself that forms the elementary cell of braided fabric also can produce deformation, banding can digest larger elastic deformation step by step, absorb, and the structural deformation finally be reflected on banding will reduce greatly.In short summarize and be exactly: the elastic deformation that the weft-knitted fabric of three-dimensional institutional framework is larger imputes to the banding of fabric, and elastic deformation digestion, absorption that will be larger, become deformation less on banding and change.Less elastic deformation make the component banding of weft-knitted fabric of three-dimensional institutional framework and hose material merge more firmly, permanent, solved the breakage problem of roller sebific duct inside.
The manufacture method of above-mentioned high roller sebific duct, comprise the following steps: the weft-knitted fabric of the three-dimensional institutional framework of woven tubular is inserted in to roller sebific duct mould screw rod core rod, after matched moulds again the hose material 180-200 degree of heating, fluidisation pours into mould, cooling forming, be made finally by the demoulding.
The described demoulding adopts pressure-air to inject between rubber tube inner wall and screw rod core rod, allows the sebific duct expansion that stretches out under the effect of pressure-air, thereby makes the demoulding of moulding sebific duct.
High roller sebific duct intensity of the present invention is high, has higher elasticity and pliability, and long service life, while rotating on high roller for a long time, can not skidded, and batches cropping pliable and toughly, makes fabric even tractive downwards, improves fabric quality.

The specific embodiment
The weft-knitted fabric of the three-dimensional institutional framework of woven tubular is inserted in to roller sebific duct mould screw rod core rod, and the weft-knitted fabric 7 of three-dimensional institutional framework can be the ingot braided structure shown in ribbed knitting structure as shown in Figure 6, the single face braided structure shown in Fig. 7, Fig. 8.The fabric of said structure is formed by the banding braiding, and banding is formed by the braiding of single fiber yarn, or after being merged by the plurality of fibers yarn, braiding forms, as shown in figure 13.
After matched moulds again hose material (rubber or polyurethane) the 180-200 degree of heating, fluidisation pours into mould, and cooling forming finally adopts pressure-air to inject between rubber tube inner wall and screw rod core rod, allow the sebific duct expansion that stretches out under the effect of pressure-air, thereby make the demoulding of moulding sebific duct.
The roller sebific duct obtained as shown in Figure 9, Figure 10.The weft-knitted fabric 7 of three-dimensional institutional framework is embedded between sebific duct outer wall and inwall, and the weft-knitted fabric 7 of three-dimensional institutional framework is single face braided structure, ribbed knitting structure or ingot braided structure, respectively as shown in Fig. 7, Fig. 6, Fig. 8.Knitted fabric shown in Fig. 9,10 is the ribbed knitting structure, and the knitted fabric shown in Figure 11,12 is the ingot braided structure.
The weft-knitted fabric of above-mentioned three-dimensional institutional framework is greater than the percentage elongation of longitudinal at latitudinal percentage elongation, therefore the latitude direction of the weft-knitted fabric of three-dimensional institutional framework is identical with the circumferencial direction of sebific duct, increases the elasticity of roller sebific duct 4.
From Figure 10,11, can find out, the existence due to the weft-knitted fabric 7 of three-dimensional institutional framework between the inside and outside wall of roller sebific duct 4 can be stretched, and has good elasticity and pliability.Weft-knitted fabric 7 structures that embed, in sebific duct, make sebific duct have elasticity and pliability preferably, changed that sebific duct produces in use for some time skid, cracking and the problem such as service life is short.
The sebific duct of this institutional framework has reduced greatly sticky suction of the yarn caused because static is excessive when work is batched and has been wound around, and coiling process is normally carried out.
Roller sebific duct 4 of the present invention and the former contrast of the sebific duct without fiber knitted network structure gummed, the intensity jail, be difficult for skidding, long service life 3-4 doubly more than.Calculate by annual 300000 consumptions in the whole world, can reduce more than 1000 ton of rubber or polyurethane raw materials consumption.Roller sebific duct long service life of the present invention, reduce the production suspension induced losses that sweater factory at ordinary times often changes expend artificial and causes because of frequent replacing roller sebific duct.
Above-described embodiment does not limit the present invention in any way, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention.
