Description

Weft thread weaving method for bamboo glass fabric

The invention belongs to TECHNICAL FABRIC and weave the field, particularly a kind of method of bamboo matter silver and fiberglass weaving well-thought-out plan glass cloth.

Traditional bamboo curtain splint loom and bamboo offset plate are to be that warp thin bamboo strips used for weaving bar is worn latitude and is interwoven with the yarn with thin bamboo strips used for weaving sheet bamboo-curtain braiding machine, and used warp density (line-spacing 6-15cm) can not satisfy weaves the Weft bamboo glass fabric requirement.Satisfying the warp yarns fabric texture with glass fiber yarn increase density requires to weave Weft bamboo glass fabric.Because of thin bamboo strips used for weaving bar bamboo curtain splint that limited length is knitted is not suitable for making stressed bamboo matter composite plate greater than bamboo bar length, also be not suitable for making continuously shaped various section bars and goods.Now weaving warp-wise bamboo curtain splint loom through bar with the yarn broadwise with the thin bamboo strips used for weaving row culture does not also have.The weaving process that warp thread and weft yarn are intertwined to form fabric on now traditional various cloth looms is cooperatively interacted by five main motions and finishes, promptly opening, wefting insertion, beat up and the warp let-off, takeup motion, loom has a mechanism to carry out these motions accordingly.These five motions have determined the kind of loom again with wefting insertion and beating motion.For example: loom, injection, arrow shaft, projectile shuttle, knit-weaving machine etc.Harness motion and opening degree should satisfy wefting insertion and the requirement of beating up, and the warp let-off and takeup motion are to cooperate wefting insertion and beating motion.One group of bamboo fiber bar radially organized weave the well-thought-out plan glass cloth with the glass fibre broadwise with traditional loom following difficult point is arranged: isolating property of bamboo material rift grain is big, therefore various thin bamboo strips used for weaving bars or bamboo chip all have the fiber thorn, the glass fiber yarn ABRASION RESISTANCE is poor again, and this just causes being not suitable for adopting traditional wefting insertion and the mode of beating up to weave the bamboo glass cloth.Even not beating up, do not adopt by traditional loom by latitude, also exist and draw single latitude or double weft wefting insertion quantity is low at every turn, knitting lock seaming when hanging down the crammed weaving yarns is difficult for, wide cut opening simultaneously will cause weft yarn rear portion linear velocity excessive, serious wear, this mainly is because fill yarns float is sunken to many bamboos in the certain thickness same plane has increased between bar due to the length of latitude paper money.

Purpose of the present invention is exactly that the speed of growth is surpassed fast-growing woods.Area and total resources and output the first in the world are cultivated by China, wide material sources, the bamboo fiber resource of the low modest superior performance of price, there are the fortifying fibre of fine intermiscibility and bamboo fiber bar warp yarns fabric texture to weave the well-thought-out plan glass cloth with glass fibre etc. is various with polymer and chlorine oxygen magnesium adhesive, glass fibre has just been eliminated the big defective of isolating property of bamboo material like this, realized the complementary intensity of bamboo glass two-phase fiber two-dimensional direction, the bamboo glass cloth is just paid good composite molding characteristic like this, make shop lamination material with the bamboo glass cloth again, doing the adhesive composite molding with polymer or chlorine oxygen magnesium is glass fiber reinforced polymer base or unorganic glass base steel bamboo fabric composite engineering material and goods, select different matrix materials and corresponding composite molding technique for use, can produce the bamboo fiber pipe that satisfies different instructions for uses, jar, the storehouse, plate, section bar, case, groove, watt, many based articles such as hull, these goods not only have the external performance that glass strengthens matrix, have also guaranteed inherent performance requirement.

Weft thread weaving method of the present invention is to use shedding mechanism warp yarns fabric texture separated into two parts, forms the full fell passage of shop latitude operation.With the getting or send shop latitude frame mechanism to coordinate alternately to connect of loom both sides, in warp yarns fabric texture fell, drive shop latitude frame and finish and get or send the shop latitude to operate with shop latitude frame.On the latitude frame of shop a plurality of cops or cop can be installed, spread the latitude operation so each time and can realize many latitudes lay.Spooler draws (drawing) to the fabric that has been made into and rolls rolling or customized cut-off becomes curtain from fell.Draw through mechanism and guarantee that warp fiber has certain tension force and can be pulled out the warp yarns fabric texture in the volume frame.Transmission mechanism guarantees between each mechanism under dynamic action, by going on foot the task of coordinating to finish separately, frame and auxiliary body guarantee locus and effective work to guarantee the quality of fabric between each mechanism, the same mechanism that finishes same work can form with different structure parts, above-mentioned job requirement is finished with corresponding mechanism according to the following steps, and to satisfy to weave the bamboo glass cloth be prerequisite, weaving other fibrid fabric only needs adjustment member mechanism to accomplish.

1, warping: all kinds of limit for length's of having bamboo strips of same scale cross dimension or bamboo chip by butt joint, finger, beat groove overlap joint etc. and glued joint into endless bamboo fiber bar.Every bamboo fiber bar is rolled into monovolume or is rolled into the group volume to one group with identical opening rule.Single or group is rolled up the cylinder shape of frame with similar cinefilm frame, also available other shape.Need roll up array by the fabric tissue width at last and become beam of a loom, in a narrow margin also can be only with a volume.

2, shop latitude frame: shop latitude frame is designed to the key shaped offset flat shape, and the major part hollow position is equipped with a plurality of shuttles or bobbin clip etc. and is used for laying a plurality of cops, cop or cop, and the yarn on cop, the cop passes separately the line hole by shaft groove separately at small end head and draws and hit.One of off working state shop latitude frame is filled cop, cop and is placed in the loom both sides along the warp-wise level and respectively has in one the latitude frame nest, and small end head points to fell, and with to be furnished with one section overlapping.Weft yarn uses up and can change shop latitude frame by hand, and that also can employ similar shuttle changing mechanism certainly changes the latitude frame mechanism, and shop latitude frame is pushed latitude frame nest in latitude frame case, changes the empty latitude frame of spreading.

3, the Shen arm of drawing back one's hand: the loom both sides respectively are equipped with the Shen arm of drawing back one's hand, and what two arms were alternately finished shop latitude frame gets or send work.Help the unloaded location of manipulator of installing unsettled arm front and spread the latitude frame and connect with getting shop latitude frame operation, guarantee that easily wide cut weaves effective location, realize easily that equally also an arm drags shop latitude asynchronous follow-up opening simultaneously, opening another arm follow-up is later got latitude, this will shorten the operation of shop latitude greatly and finish the back and wait for and getting the latitude operating time that this point is weaved highly beneficial to raising wide cut bamboo glass cloth.The Shen arm of drawing back one's hand can have multiple implementation method, and this machine selects for use the hinged travel prolongation mechanism of rhombus to finish this work.

4, manipulator: also can drag the manipulator that shop latitude frame moves the shop latitude by rotatable can a connection with shop latitude frame major part is housed before the arm, the lower berth latitude frame drive manipulator that stops at fell horizontally rotates an angle, reverse at manipulator and arm and to make shop latitude frame small end head be close to fell shop latitude all the time under the yellow effect of bullet, latitude stroke end shop, shop latitude frame recoils to the arm plumbness and is brought into the latitude frame, and manipulator unclamps and spreads latitude frame return simultaneously.Shop latitude frame waits the other side's arm to get the operation of latitude frame in latitude frame nest.Manipulator and the many kinds of modes that are connected with of spreading the latitude frame, this manipulator connects with shop latitude frame major part side arm double-pin lockhole plug with compound double-pin skew bolt lock, and is compound in order to guarantee effectively to connect and reduce the suffered torsion of single shank.The inclined tongue of lock pin is hinged with palm with one on a long oblique tongue lever, and adjacent have an oblique projection, and it is oblique tongue that opposite side has the yellow other end of pressure bullet, and lever is placed in that oblique tongue is forced out outside the shank in the shank under the elastic force effect.When getting shop latitude frame operation with arm, when the manipulator shank inserts latitude frame lock hole, shop, be pressed in the shank at the pressure declivity tongue of hole arm, tiltedly tongue is by ejecting locking shop latitude frame behind the arm of hole.Pawnshop latitude frame is taken back the oblique projection that latitude frame nest retreads on the tongue lever and is depressed, and lever rotates around pin joint, makes in the oblique tongue withdrawal shank of other end, extracts lock in latitude frame lock hole, shop.Manipulator has a pair of alignment pin corresponding with a pair of horn mouth on the machine frame at two sides, connects to guarantee that lock is accurately located with shop latitude frame.Horn mouth is positioned on and is not subjected to size restrictions can guarantee accurate location on the frame.

5, shedding mechanism: the wefting insertion of Weft thread weaving and shop latitude and traditional wefting insertion with beat up weave different, therefore also different to the requirement of fell, do not need the conventional steel latitude of cramping, with traditional heald frame opening fell just by heald frame in two, steel wire heald also is not suitable for using between the different size bamboo fiber bar (the wide 1-5mm of 4-5mm is thick) and adjusts size and pass.Pass through in order to ensure shop latitude frame and the Shen arm of drawing back one's hand, enough big fell passage must be arranged.When weaving, wide cut should be able to realize asynchronous follow-up opening.There are many kinds of mechanisms can realize these requirements.Swing cantilever relatively with two of a pair of gear drivens, cantilever is left behind the bamboo that passes masthead portion bamboo bar folder and provoke through bar and makes it that stroke distances be arranged, and just can determine stroke distances by adjusting pendulum angle or jib-length.Allow a pair of both arms band bamboo be rocked to range and just form a full fell through bar, form one group of shedding mechanism and be connected with power by one or more pairs of both arms by crank, one group of shedding mechanism can be used a pair of gear driven, can form a warp yarns fabric texture by one or more groups shedding mechanism.The fabric tissue of being made up of many groups shedding mechanism can be realized asynchronous opening follow-up and get the latitude follow-up and get ready for asynchronous.

6, spooler: Weft thread weaving spooler and traditional loom are basic identical, different is that the yardage roll radius of gyration is big, only need be adjusted into traditional spooler and be fit to cloth-winding mechanism and batch the major diameter yardage roll, require and can smoothly pull out the requirement that cuts into curtain.Bamboo has good tensile strength therefore to batch pressue device with spring through bar increases pulling force, pulls out bamboo through the bar fabric tissue by the opening cantilever top from row's volume frame.The bamboo glass cloth of selecting for use the batch (-type) spooler to be fit to each many latitudes lay batches.

7, draw through mechanism: drawing through mechanism of Weft thread weaving is identical with the warp-feeding mechanism effect of traditional loom passive type, the structure difference.Be not both by many monovolumes or group volume frame with traditional monoblock type beam of a loom and combine beam of a loom.It is to have volume bamboo to hold up through row's volume frame of bar with carrier roller frame, makes the rotation of carrying roller volume backward rotation tension bamboo through bar by friction, batches pulling force greater than reverse friction when spooler is worked, and all bamboo is drawn out through bar and becomes the warp yarns fabric texture.When a volume bamboo after bar uses up, in a row volume frame, extract the blank coil frame out, change on another cigarette bamboo and turn back to original position through bar and get final product.

8, transmission mechanism, the transmission mechanism of Weft thread weaving can be machine driving (electronic transmission), hydraulic pressure, fluid power, Pneumatic Transmission etc., also can be the compound transmissions of these transmissions, to realize that accurately, efficiently, easily automation is controlled to be prerequisite.Determine connecting mode between each mechanism according to selected transmission mechanism.The Pneumatic Transmission of this machine, but like this between the each several part mechanism machine driving also can make up very convenient by the independent transmission of discrete cylinder.
