Description
Technical field
The invention belongs to technical field of knitting machinery, and in particular to a kind of secondary roller device of computer plain flat knitter.
Background technology
Main roller device and secondary roller device is commonly equipped with computer plain flat knitter.Secondary roller device is in computer pin
The particular location on flat knitting machine is knitted corresponding to a pair generally in splayed（Or claim herringbone）The forward and backward needle-bar of distribution（Also referred to as
Forward and backward needle plate）Centromedian lower section, and as close to tube port position, that is to say, that require the position of secondary roller device to the greatest extent
May be near nozzle.Concept with regard to nozzle can be found in the specification of Chinese invention patent application publication No. CN101225576A
The 3rd section of page 7.Aforesaid main roller device is located at the lower section of secondary roller device, will be by computer plain flat knitter by secondary roller device
The fabric that completes of knitting mechanism braiding drawn under state downwards in seizing on both sides by the arms, supply main roller device and by main roller device
Then draw, supply follow-up cloth beam and batch.
By explanation above, secondary roller device is the knitting mechanism and main roller machine between computer plain flat knitter
Transition mechanism between structure.Why auxiliary roller mechanism is called transition mechanism, is because that main roller mechanism had both been subject to left and right needle-bar
（Forward and backward needle-bar can also be claimed）Between narrow space restriction, and by self structure restriction and cannot be close to aforementioned
Tube port position install, unless first knit out one section with refuse yarn before formal braiding to braid is entered be enough to for main roller machine
The useless braid of structure traction（Transitional weave thing）.However, using refuse yarn in advance（The relatively low yarn of class）The useless braiding of one section of braiding
The disposal options of thing are more harm than good, for disadvantage, not only affect braid efficiency, that is, delay computer plain flat knitter be directly entered right
The time of the woven condition of fabric, and refuse yarn line is wasted, it is the drawbacks of more main if directly led by main roller mechanism
Draw braid, then because the uniformity of traction force is difficult to or even cannot ensure at all, i.e., cannot lead under preferable moderate tension
Draw fabric, the final normal knitting for affecting knitting mechanism, or even braiding is carried out.
In view of above-mentioned factor, is no lack of the secondary roller device with regard to computer plain flat knitter in disclosed Chinese patent literature
Technical information, such as CN10055455B（The secondary roller machine of computer plain flat knitter）、CN101956291A（Computer-controlled flat knitting
The auxiliary roller mechanism of machine）、CN104233619A（The selvage guide laura structure of computer plain flat knitter）、CN201186879Y（Computer

The good and bad cloth effect of holding under the arm that can be covered on holding cloth under the arm produces corresponding impact, that is to say, that the flatness of roller body is glacing flatness and braiding
It is closely related that thing draws effect.However, the door width with braid（That is width）Increase, the knitting mechanism of computer plain flat knitter
Gradually from single system to two systems, three systems or even four System Developments, then the length of roller body also accordingly increases.Typically
Such as：In carpet woven or similar broad fabrics, it is common to use the knitting mechanism of three systems, the length of roller body reach
The even longer degree of 2m to 3m, and also have the trend for gradually increasing.According to common knowledge, the length of roller body is longer,
Amount of deflection is more also easy to produce, and once produces amount of deflection, then the uniform traction force of the width to braid cannot be ensured, affected
Braid is held under the arm the stability that cloth set is held under the arm out.It is embodied in：Due to the centre of roller body weak, thus the width to braid
The power of seizing on both sides by the arms at the middle part in degree direction is significantly inferior to both sides.Although rationally the diameter of increase roller body and rigidity can be certain
Avoid producing amount of deflection in degree, but it has been observed that as the space of tube port position is extremely limited, thus the diameter of roller body is objective
On be restricted because will necessarily accordingly increase which after directly increasing the distance between with nozzle, and the distance for leaving nozzle is got over
Greatly, the drawing effect to braid is poorer, and increases the electric energy that the diameter of roller body can cause previous power transmission mechanism
Consuming increases, and is unfavorable for energy-conservation.
