Description
Technical field
The invention belongs to textile machine equipment technical field, more particularly, to a kind of small-bore circular knitting machine yarn adding device.
Background technology
Circular knitting machine is that yarn is formed into coil using knitting needle of the configuration on circular syringe, then connects into cylinder by snare
The knitting machine of shape weft-knitted fabric, it to yarn mechanism, knitting mechanism, drawing-spooler and transmission mechanism mainly by forming.Selection
The syringe of different type and bore, the fabric tube for industrial or agricultural and biomedical sector can be produced, it is for example small
Bore circular knitting machine can be used for preparing medical human tubular bracket, such as Chinese invention patent (publication number：CN103705325A in)
The intestinal stent, formed using the braiding of small-bore circular knitting machine.
In view of the Multi-level Organization Structure (such as epidermis, muscle layer and internal layer) of human body itself pipeline and tubular bracket is more
Layer function (medicament slow release layer, degradable material layer and organizational project composite bed), can have by introducing yarn adding device and simulating
The bionical medical tubular rack of sandwich construction.Plating structure is also known as " lid hair tissue " and " interlaced structure ", is by two kinds or two kinds
Different yarns above to knitting needle band yarn, make the positive and negative of fabric form the coil of different colours and different-style simultaneously.Add
Yarn tissue is widely used in the various coil tissues by the fabric of circular knitting machine braiding, when circular knitting machine weaves, it is desirable to veil phase
Feeding point and vertical angle for knitting needle are respectively less than the band yarn transverse and longitudinal angle of filling, in order to which knitting needle hooks up veil and filling simultaneously,
After overturning lopping, veil is presented on the front of fabric through upset, and filling is presented on the reverse side of fabric through upset.Due to plaiting
Tissue surface's yarn coil overlaps above ground yarn coil all the time, thus during braiding, to knitting needle, yarn guide, yarn tension, plaiting angle
Degree has particular/special requirement, and its technological requirement is higher, the improper coverage effect that can influence two or more coils of parameter designing,
So as to influence the outward appearance of fabric.
Existing yarn adding device is complicated, and cost of manufacture is high, installation and maintenance trouble, is not easily adjustable technological parameter.
One one thread individually can only effectively be fed using the yarn adding device of override interrupt, or feed two in a guide eyelit simultaneously
Yarn, but two one threads are easily mutually wound, it is impossible to multi-layer braided structures requirement is realized, and yarn tension can not be surveyed online
The problems such as amount is with regulation, such as Chinese patent (publication number：CN204589494 U) described in adding set.Therefore, invention is a kind of uses
It is significant in the yarn adding device with weft tensioner of small-bore circular knitting machine.
The content of the invention
The present invention seeks to：There is provided one kind to be not only simple in structure, and lapping position and adjustable angle can be realized, simultaneously

The technical scheme is that：A kind of small-bore circular knitting machine yarn adding device, including be fixed on syringe working face
Support bar, located at the arrangement for adjusting height of the supporting bar top, the rotation adjustment device being connected with the arrangement for adjusting height,
And the plaiting lever jack being connected with the rotation adjustment device；Plaiting yarn guiding assembly is installed on the plaiting lever jack；
The plaiting yarn guiding assembly includes being installed at least one guide tripod of the plaiting lever jack upper surface, and with it is described
The Yarn-guiding mouth of plaiting lever jack end connection；Several guide eyelits arranged in parallel are provided with the head end of the Yarn-guiding mouth, can be with
More different wire gauzes and veil are introduced simultaneously, so that the braiding requirement of different plaited fabrics can be met.
As preferable technical scheme, the arrangement for adjusting height includes the gear that about two engagements are set；The rotation
Modulation regulating device includes pivoting lever, and the rotation for connecting the pivoting lever and the plaiting lever jack is adjusted
Nut；And gear above is fixedly connected with the pivoting lever top, by adjusting the tooth matching angle of two gears,
Adjust the height and angle of Yarn-guiding mouth.
As preferable technical scheme, the rotation adjustment device includes the revolute pair being set on the support bar, institute
The set screw that arrangement for adjusting height includes being installed in the revolute pair is stated, the revolute pair passes through prismatic pair and the plaiting
Lever jack connects.
As preferable technical scheme, adjusted on the plaiting lever jack, positioned at the guide tripod and the rotation
Yarn tension controller is installed, measurement in real time and the function of regulation plaiting tension force between regulating device.
As preferable technical scheme, the guide tripod is provided with two symmetrically arranged guide eyes, and described
Positioning hole and the pin in the positioning hole are installed in the middle part of guide tripod, in the plaiting lever jack bottom, are located at
The pin bottom is provided with fixing nut.
As preferable technical scheme, the support bar bottom is fixed on the syringe working face by nut.
As preferable technical scheme, hollow structure is used inside the Yarn-guiding mouth.
It is an advantage of the invention that：
