Description
Technical field
The invention belongs to technical field of knitting machinery, be specifically related to a kind of secondary roller device of computer plain flat knitter.
Background technology
Computer plain flat knitter is equipped with main roller device and secondary roller device usually.The particular location of secondary roller device on computer plain flat knitter is the Centromedian below of the forward and backward needle-bar (also claiming forward and backward needle plate) that splayed (or claiming herringbone) distributes corresponding to a pair substantially, and as far as possible near tube port position, that is require that the position of secondary roller device is as far as possible near nozzle.Concept about nozzle can see the 7th page the 3rd section, the description of Chinese invention patent application publication No. CN101225576A.Aforesaid main roller device is positioned at the below of secondary roller device, the fabric woven by knitting mechanism by computer plain flat knitter by secondary roller device draws downwards being under the state of seizing on both sides by the arms, supply main roller device and then drawn by main roller device, supplying follow-up cloth beam and batch.
Known by explanation above, secondary roller device is the transition mechanism between the knitting mechanism and main roller mechanism of computer plain flat knitter.Auxiliary roller mechanism why is claimed to be transition mechanism, because main roller mechanism had both been subject to the restriction of the narrow space between left and right needle-bar (also can claim forward and backward needle-bar), be subject to again the restriction of self structure and cannot installing close to aforesaid tube port position, unless first knit out one section of useless braided fabric (transitional weave thing) be enough to for main roller mechanism traction with refuse yarn before entering the formal braiding to braided fabric.But, refuse yarn (yarn that class is relatively low) is used to weave the disposal options of one section of useless braided fabric in advance more harm than good, with regard to fraud, not only affect braid efficiency, namely the time that computer plain flat knitter directly enters the woven condition to fabric is delayed, and waste refuse yarn line, more main drawback is if directly draw braided fabric by main roller mechanism, so because the uniformity of traction force is difficult to cannot ensure even at all, namely fabric cannot be drawn under desirable moderate tension, the final normal knitting affecting knitting mechanism, even makes braiding carry out.
In view of above-mentioned factor, the TECHNICAL INFORMATION SOURCES of the secondary roller device about computer plain flat knitter is no lack of in disclosed Chinese patent literature, secondary roller machine as CN10055455B(computer plain flat knitter), the auxiliary roller mechanism of CN101956291A(computer plain flat knitter), the selvage guide laura structure of CN104233619A(computer plain flat knitter), the roller rod of CN201186879Y(Computerized flat knitting machine improvement) and the auxiliary roller mechanism of CN201801707U(computer plain flat knitter), etc.
By particularly known to the reading of CN104233619A to being not limited to aforementioned patent literature: the structural system of secondary roller device is by that right form occurs and respectively by roller body, transition roller, support member with hold cloth cover under the arm and form to be made in a state of use, the lower support of the length direction of support member is in roller body, and match with transition roller in the top of the length direction of support member, hold cloth cover under the arm and to be nested with on transition roller and roller body and by support member envelope.During use, under the work of power drive mechanism, roller body is rotated, made by the rotation of roller body to hold cloth cover under the arm around roller body and transition roller motion, the fabric that knitting mechanism by computer plain flat knitter has woven is caused and holds under the arm between cloth cover, hold under the arm out by holding cloth cover under the arm, for the main roller mechanism in rear road, and then the work beam (cloth beam) of supply spooler batches.Aforesaid by power drive mechanism drive roller body rotate relevant technical information can emphasis see CN201801707U.
Aforementioned roller body is the critical component of secondary roller device, one end of its length direction can produce corresponding impact to the cloth effect of holding under the arm of holding cloth cover under the arm to the quality of the levelness of the other end, and that is to draw effect closely related for the flatness of roller body and glacing flatness and braided fabric.But, along with the door width (i.e. width) of braided fabric increases, the knitting mechanism of computer plain flat knitter gradually by single system to two systems, three systems and even four System Developments, so the also corresponding growth of the length of roller body.Typical as: when carpet woven or similar broad fabrics, generally use the knitting mechanism of three systems, the length of roller body reaches the even longer degree of 2m to 3m, and the trend increased gradually in addition.According to common practise, the length of roller body is longer, more easily produces amount of deflection, and once produce amount of deflection, so cannot ensure the uniform traction force of the width to braided fabric, affects braided fabric by the stability of holding cloth cover under the arm and holding under the arm out.Be embodied in: because the centre of roller body is weak, thus significantly both sides be inferior to the power of seizing on both sides by the arms at the middle part of the width of braided fabric.Although the diameter and the rigidity that rationally increase roller body can be avoided producing amount of deflection to a certain extent, but as aforementioned, because the space of tube port position is very limited, thus the diameter of roller body is objectively restricted, because will inevitably distance between corresponding increase itself and nozzle after directly increasing, and the distance leaving nozzle be larger, poorer to the tractive effect of braided fabric, and the diameter increasing roller body can cause the power consumption of previous power transmission mechanism to increase, and is unfavorable for energy-conservation.
" Computerized flat knitting machine monoblock type semicircle supports secondary roller " that utility model patent Authorization Notice No. CN2890114Y recommends changes an overall cloth drawing pole relative to the cloth drawing pole in prior art into by two sections of connections, although and overall cloth drawing pole can reduce the number of parts, easily produces amount of deflection.The cloth drawing pole that on the contrary this patent connects as the two-part of prior art can alleviate amount of deflection to a certain extent.But, the shape of cross section of the cloth drawing pole (patent claims secondary cloth drawing pole) connected due to this two-part is quincunx, and direct and clothing in contact under granny rag state, thus be not the structural system of aforementioned auxiliary roller device, thus easily on cloth cover, form indentation when a pair cloth drawing pole cooperatively interacted is at granny rag, and be not suitable for the traction to the high fabric of class requirement.In addition, the structure of the secondary granny rag of the Computerized flat knitting machine mentioned in background technology hurdle of this patent is connected little axle by two sections of secondary cloth drawing poles with two sections and a bearing is formed, bearing is connected being bonded with each other of little axle corresponding to two sections of secondary cloth drawing poles and locates with two sections, specifically, the outer ring (rotatably) of the abutting end in opposite directions of two sections of secondary cloth drawing poles and bearing is fixed, and the inner ring (not rotating) of the abutting end in opposite directions and bearing that connect little axle by two sections is fixed, so the length connecting little axle due to two sections need be equal with the length of two sections of secondary cloth drawing poles, thus cause whole secondary roller device heavy on the one hand and be unfavorable for that saving is for ordering about the power consumption of the power drive mechanism of secondary cloth drawing pole motion, cause the increase of manufacturing cost on the other hand.Therefore for the amount of deflection of roller body solved in the structural system of above mentioned secondary drawing device, not there is substantial enlightenment effect by the aforementioned structure introduced in the background technology hurdle of this CN2890114Y.
