Description
Technical field
The present invention relates to limit yarn tension controlling organization and Method And Principle in a kind of printed circuit board industry enhancing electronic grade glass fibre ultrathin fabric weaving process.
Background technology
As the basic reinforcing material supplier of PCB industry, along with the continuous upgrading of industry in recent years, the extensive use of high-density multi-layered printed wiring board, the models such as 1080# type electronics cloth and thinner 106#, 1037#, 1067#, 1027# present blowout formula and increase, but ultrathin fabric is because its difficulty of weaving is large, yields is low, technical threshold is high, domesticly still cannot provide, and supply mainly concentrates in the Japanese and minority Taiwan investment manufacturer hand such as Japanese NTB, UNITIKA.Ultrathin fabric has weaved a lot of difficult point, and wherein the left side warp tension (picking side) of warp beam controls, strand limit is bad, split the abnormal high-lighting problem being restriction ultrathin fabric and developing occurred frequently such as bad selvedge, running.To this, glass cloth manufacturer adopts and reduces rotating speed, loss yields and cost substantial contribution research and development electronic edge yarn tension controller and reach production object, but the yield of ultrathin fabric maintains a lower level all the time.
Existing ultrathin fabric weaving technology grows up in the production technology and production equipment of thick cloth (as 7628#), because the inherent shortcoming on its equipment and process makes it be difficult to break through weaving of ultrathin fabric, and inefficiency, cloth cover poor quality.
The selvedge tension control mechanism that the invention discloses designed, designed can effectively reduce even eliminates that strand limit is bad, to split the cloth cover such as bad selvedge, running abnormal, and simple and practical, convenient operation, improves production efficiency and the glass cloth interior quality of machine greatly.
Summary of the invention
Electronic grade glass fibre ultrathin fabric is commonly referred to as basic weight at 30g/m
2below, the glass fabric of thickness below 40 microns, its yarn used is generally below filament diameter 5um, number several 5.5 Tekes (Tex) below, so thin yarn proposes high requirement to the preparation (whole slurry through technique) before weaving, nonetheless by the subsequent affect of knitting front technique and bringing, weaving of ultrathin fabric is still made to bring tremendous influence.Superfine yarn tangles very easily mutually when whole slurry, lap wound, especially at the Bian Panchu (especially attaching most importance to limit, left side dish) of beam of a loom, the warp thread tangled easily produced the phenomenon of pine or tension, when there is problems in weaving time, because of the fluctuation of limit yarn tension, strand limit, left side becomes very difficulty.The yarn linear density that strand limit yarn uses normally stitch yarn 1/2 ~ 1/3, superfine strand limit yarn very easily broken when tension fluctuation, and then the running of selvedge, to split the float such as bad selvedge namely inevitable.The process of this type of exception needs the time of at substantial, and loom efficiency is low.Glass jet shuttleless loom simultaneously as main flow has strict requirement for the readability of fell, hightension, high traverse, high pressure are smooth woven prerequisites, but hightension, high traverse are for superfine glass warp thread simultaneously, particularly the warp thread injury of left side cloth avris is also very serious, fabric width direction convergent force and warp-wise tension force and and knit the longitudinal frictional force between tool acting in conjunction under, left side warp thread can become and be very easy to fracture and fluff, and the quality and weaving efficiency that make fabric have no to ensure by this.For improving the difficult point that above all tension force controls, the present invention adopts unique mechanism design, and design solves above-mentioned difficult point cleverly, makes ultrathin fabric be able to scale of mass production, breaches and weave bottleneck.
The present invention need protect technical scheme be:
Limit of the present invention yarn tension controlling organization comprises left regulon, right side regulon, lay respectively at the right and left side of loom, described left regulon comprises again main burner 5, left scissors 4, adjuster 2, strand limit yarn 3, fell (meaning not shown in the figures, be known in the art term), fell base 10
The active section of adjuster 2 is suspended from fabric, and its stiff end is fixed on fell base 10, and the strand limit that strand limit yarn 3 is formed is limited in the inner cavity of its active section by adjuster 2 all the time, forms left cell thus to the pressure of cloth cover and spacing;
Warp thread through reed, on reed seesaws and is positioned at weft yarn formerly between upper and lower two-layer warp thread fell border;
Picking yarn sprays to the right from main burner 5, through the fell that upper and lower two-layer warp thread is formed;
Described right side regulon comprises again She Er yarn 9, abandons limit yarn 12, fell base 10, right scissors 11, She Er yarn 9, abandon limit yarn 12 and be all positioned on fell base 10; Twisted by She Er yarn 9 after described picking yarn moves to right side regulon and form picking yarn tension, when picking yarn tension reaches loom control system preset setting value, the left scissors 4 of loom Systematical control performs cuts off picking yarn, and the tension force achieving weft yarn controls and cuts off; Cut off rear formation new abandon limit yarn;
What keep the same quantity of twisting in She Er yarn 9 abandons the cloth surface pressure that limit yarn forms right sided cell, corresponding to the cloth surface pressure of left cell, contributes to the plane control to fell and cloth cover;
Right scissors 11 for cut off formerly abandon limit yarn, depart from from original She Er yarn 9 limitation ot it;
After action cycle terminates, main burner 5 sprays new picking yarn to the right;
Under the synergy of left regulon adjuster 2; balance is formed between two regulons in left and right; cloth cover obtains excellent control; strand limit yarn and limit yarn are on same horizontal plane; strand limit obtains best protection; and the limit yarn tension of longitudinal direction also can be controlled, solve the problem of limit yarn tension inequality ripping.
Optimal design, the inner cavity of active section is designed to arc curve shape, guarantees that the tension force of the strand limit yarn 3 contacted with it can seamlessly transit.
Optimal design, the active section of adjuster 2 is suspended from the fabric that is positioned near beat-up line.
The mechanism design of uniqueness of the present invention makes strand limit yarn and limit yarn be on same horizontal plane, before loom is in time dead point (0 degree of angle), strand limit yarn and limit yarn are in tensioning state, such design can overcome the impact of fluctuation for selvage forming of limit yarn tension, avoids the generation split bad selvedge, twist the exceptions such as limit is bad, running.
The distinctive localized design of the present invention makes loom in high speed wefting insertion, fell place, left side warp thread can be limited under the effect of glass cloth fabric width direction convergent force, rise or decline, reduce cause because of its unsuitable forced position under large traverse, high tension forces for the impact that left side warp thread fractures and fluffs, loom efficiency is got a promotion.
When reed is when 0 ~ 180 degree of wefting insertion is interval, mechanism of the present invention can effectively reduce because fell forms the problem that the limit yarn tension that causes sharply increases, because when fell is opened, whole shedding motion runs up and down, and now limit yarn tension is maximum.Bound is to the inner cavity of adjuster 2 active section of left regulon, and thus reduce the traverse of limit yarn, reduce limit yarn tension, the arcuation inner cavity stretching into adjuster 2 active section ensure that seamlessly transitting of tension force.When reed 181 ~ 360 degree beat up interval time, mechanism of the present invention can limit the free degree in strand limit yarn and yarn fabric width direction, limit, because when fell closes, cloth width will get back to maximum fabric width under the promotion of reed, limit yarn tension raises again, reduce the increase of limit yarn tension whereby, thus the weaving efficiency of glass fibre ultrathin fabric can be improved, reduce and even eliminate that strand limit is bad, to split the selvedge such as bad selvedge, running abnormal, promote the production efficiency of fiberglass woven cloth machine and the exterior quality of glass fibre ultrathin fabric product.
