Description

A kind of basalt grid weft yarn instant twister online

Technical field

The utility model belongs to twisting equipment technical field, and in particular to a kind of basalt grid weft yarn is twisted immediately online Device.

Background technique

Glass fiber grid improves pavement loading endurance, extension road surface makes as reinforcing rib earth working material during building the road With the service life by wide popularization and application.But in the case where extreme condition and very harsh requirement, glass fiber grid is just difficult to reach to want Ask, such as the variation of high temperature, high and cold or day and night temperature very greatly in the case where or the runway that is gone up and down for airport.Basalt fibre sheet Body has strength more higher than glass fibre, bigger modulus and impact resistance, better wearability, better high temperature resistant and resistance to The characteristics of freeze thawing, so wouling have in the case where some crucial, special with basalt grid.Produce basalt grid institute Basalt fibre roving, be with the parallel precursor of multiply in the state of not twisting and close made of bulk.Profound In military rock rove bulk, parallel protofilament convergence is very poor, precursor is in dispersity, and multiply precursor and closes When, since the tension between precursor is different, makes and the rove closed has tightly in tensioning state Shi Yousong, while because of basalt fibre sheet Body modulus is big, rigidity is strong, is easy to be broken off the easily formation " filoplume " when there is resistance.Basalt fibre is used as weft yarn using warp When compiling woven TGXG, 12 weft yarns pass through 12 porcelain eyes on Weft laying trolley, have Weft laying trolley to drive in 6 meters of breadth Latitude is back and forth spread on tricot machine.12 weft yarns that trolley is spread are held and simultaneously with completing by the weft gripper of tricot machine two sides Weft yarn travel forward.When weft yarn moves forward to knitting zone (binding area), by the very thin polyester filament line of knitting mechanism The weft yarn being laid on warp thread is formed by crosspoint to bundle, forms sheet fabric-grid of mesh.By with The basalt rove for making weft yarn is made of not twisted and closed in parallel as multiply precursor, this results in the precursor of formed rove Tension is inconsistent.Rove in a tensioned state, wherein some precursor are still in relaxed state.In this case, bundle is moved to Binding needle, the line that tying up the rove (weft yarn) in area cannot be run at high speed bundle, or even can also damage binding crochet hook and lead to nothing Method normally produces.When 12 weft yarns carry reciprocal paving latitude by Weft laying trolley, each paving latitude is reciprocal, the variation of weft yarn movement velocity All be: static-acceleration-deceleration-is static；Then it returns: static from static-acceleration-deceleration-.So the stress of weft yarn It is also in variation, when weft yarn moves to tricot machine two sides, after being held by weft gripper, the direction of motion moment of weft yarn transfers 180 °, the stress of weft yarn is very big at this time.Because basalt precursor parallel and while closing there is no the twist and basalt fibre have it is rigid Property big feature form " filoplume " blocking guide eyelit so basalt filament is easy to be broken off and influence to produce.Although the Black Warrior Rock grid has lot of advantages, but the method because of basalt fibre performance itself and its rove and when closing processing, determines the Black Warrior The structure of rock rove, so to carry out specially treated to weft yarn, otherwise basalt grid just can not when producing grid with basalt Production.

The specification of multiply basalt precursor as requested passes through buncher multiply wound in parallel and closes, and forms diameter one The yarn group of cause.It is fixed for doing the yarn group outside of weft yarn with heat-sealing film heat sealed package, yarn group inner hole is lined with paper tube.Under normal circumstances Yarn group's inner hole is without paper tube, and yarn is to be extracted to use from yarn group inner hole when yarn group uses, and yarn group remains static.Work as multiply Precursor is parallel and the basalt rove that closes does weft yarn in use, fiber when in order to solve its rove and close being used to manufacture grid The inconsistent problem of tension, must just twist rove, and yarn group is allowed to rotate.So rove is (profound from outside unwinding use Military rock thick line works as warp thread in use, inner hole does not put paper tube, and rove is unwound from inside, and yarn group remains static).

Be to the principle of Yarn twisting in existing textile industry: the yarn group being twisted remains static, and yarn is from yarn group On be drawn out on the spool of twisting spindle, spindle drives spool high speed rotation, and yarn is coupled with the twist and will add the twist simultaneously Yarn be wrapped on spool, complete twisting to yarn.

Basalt rove " immediately online twisting " in the utility model and the Yarn twisting in textile industry just on the contrary, It is that rove is twisted in the yarn group rotation being twisted, the rove of the twist then will have been added to release from yarn group to be made immediately With twisting of the completion to rove.

The composition and principle of basalt grid weft yarn twisting mechanism:

1. twister includes yarn group placement mechanism, fixed mechanism and transmission mechanism three parts composition.The first, yarn group places Mechanism: in the outside of twisting rotation axis, six pieces of arc tension blocks are placed with around twisting rotation axis.On the spindle nose of twisting rotation axis There is rotation bolt, is adjusted by rotation bolt and be covered in circular shaft composed by the axial six pieces of arc tension blocks of twisting rotation The size of diameter.When yarn group is put into, six pieces of arc tension blocks are in deflated state, and diameter is less than yarn and rolls into a ball the interior straight of interior spool Diameter, in order to load and unload.After yarn group puts well, bolt is rotated, six pieces of arc tension blocks in deflated state extend to the outside, will The yarn of loading rolls into a ball tensioning, is integrally formed yarn group with twisting rotation axis, and yarn group rotates together with rotation axis.Placement mechanism is rolled into a ball in yarn Below be fixed with round tray, diameter 340mm(yarn rolls into a ball the not super 300mm of maximum gauge), be integrated with rotation axis.Yarn group puts It sets on pallet, is rotated together with yarn disk.The second, in the lower section dress of yarn group pallet, there are two bearing blocks, will be added by bearing block Twisted moving axis is fixed on the rack.The upper plane of all twisting rotation axis all necessary vertical frames when fixing on the rack, to protect Stability when card twisting rotation axis drives yarn group to run at high speed.Third, the twisting rotation axis that is vertically fixed in rack Bottom is equipped with belt pulley, and belt pulley is connected to motor by V-belt, and motor speed is by Frequency Converter Control, a motor drive One twisting rotation axis individually controls.8 rotation axis are housed in every rack, it can be simultaneously to 8 yarn group twisting.When needing to twist Yarn roll into a ball more than 8 such as 12, (16 twisting rotation axis only use 12 to optional 2 twisting equipment, remaining 4 are spare.Often Platform twisting mill also mountable 8 or more twisting rotation axis, but if installation is excessive first is that equipment heaviness is not well placed, second is that behaviour It is inconvenient to make).

2. rack section；8 groups of twisting rotation axis are divided into the two sides that 2 straightened portions are mounted on rack, 4 groups of every side, and every two groups Between distance of shaft centers be 800mm(general basalt yarn group specification are as follows: height 260mm, 250~300mm of diameter, diameter of bore 75mm).The size of rack are as follows: long * wide * high=3200*1800*600, motor are mounted on the following crossbeam of frame central, belt Disk is downward and the belt pulley of twisting rotation axis is in same level.Each twisting rotation axis has a motor to drive.In machine In rack beside frame two sides, every twisting rotation axis, it is all respectively provided with shield screen covering and yarn circle protector, prevents yarn group high speed from turning Influence of the looping that effect rove when dynamic because of centrifugal force is formed to twisting.

3. protecting screen covering.One shield screen covering is installed in the surface of each twisting rotation axis basalt yarn group, shield screen covering is in circle Cone cell is equipped with porcelain eye on vertebra point, is exported after the twisting of basalt rove by porcelain eye.Shield screen covering is made into stainless steel plate, inside Want smooth, seam cannot hang yarn.Shield screen covering has rocking lever to be fixed by vertical rocker arm fixed link, and rocking lever is rectangular in shape, and erects on one side Straight cutting enters in rocker arm fixed link, and another side rocker arm horizon bar is connected with shield screen covering conical points below porcelain eye.Rocker arm horizon bar will protect Screen covering is vertically hung in the surface of twisting rotation axis, and the yarn group of one third height is covered.Shaking in insertion rocker arm fixed link Arm vertical bar can be extracted out and be able to rotate from fixed rod tube.It, can be by rocker arm when basalt yarn group needs replacing or when handling failure The basalt yarn group protected under screen covering is exposed and carries out changing yarn or troubleshooting, after being disposed again by vertical bar extraction, turn away By shield homing.When rocking lever is in the working condition right above yarn group, have one between rocker arm fixed link and rocking lever Positioning pin fixes shield screen covering, it is ensured that high speed rotation twisting, the rove unwound shroud in shield screen covering.

4. yarn circle protector；Yarn circle protective device-yarn circle protection is housed below the centre that the basalt yarn of rotation is rolled into a ball Device, the formation of yarn circle when prevention yarn rolls into a ball high-speed rotation.Yarn circle protector is that have two horizontal reinforcements and a vertical annulus and not The rectangular frame that the steel plate surface that becomes rusty forms, casing are mounted on the pedestal on the outside of rocker arm bottom of fixed, by torque spring to yarn Enclose the certain torsion of protector, include yarn circle protector be fixed on pedestal swivel mount on the outside of rocker arm bottom of fixed, Drive vertical direction frame reverse in the horizontal plane, by be mounted on the rectangular frame other end, with certain arc not Rust steel plate tightly sticks on the outside (can not disengage when yarn rolls into a ball high speed rotation) of yarn group, the basalt for unwinding high speed rotation Rove is under the action of the shield yarn stainless steel plate tightly sticked, because the coil that high speed rotation centrifugal force is formed is deteriorated, rove It is tightly sticked on surface, side that yarn is rolled into a ball to be twisted, while exporting from the porcelain eye hole on taper shield screen covering top.

It will be taken as the inner hole that weft yarn uses to be placed in twisting rotation axis with the basalt fibre group for knitting pipe, screw twisting Bolt above rotation axis keeps basalt fine under the action of twisting rotates the twisting six pieces of tension block expanding forces in rotation axis surface Group is integrally formed with twisting rotation axis.Basalt yam head is passed through to the porcelain hole on taper shield screen covering top, then will protect screen covering lid In the surface of yarn group.Specification requirement according to the production of basalt grid is different, at the same the fill yarn ends used have 6,8, The differences such as 10,12 can determine the quantity of twisting rotation axis according to the radical of weft yarn actual requirement.Each twisting rotation axis point There are not a motor and frequency control, which group is used when which group twists rotation axis can start, unused not open.Apart from ground 2 Yarn poteye, porcelain eye of the basalt rove from taper shield screen covering top are equipped with right above every twisting rotation axis of height of rice In export vertically upward, the Weft laying trolley of tricot machine is redirected by the yarn poteye of surface, with the water of Weft laying trolley It is flat to move back and forth, complete the paving latitude work of basalt grid.General 5 twists/m of quantity of basalt twisting as weft yarn, That is one meter of twisting rotation axis of the every output of weft yarn will turn 5 circles.Because the motor of twisting is by Frequency Converter Control, when production The speed that motor can be adjusted according to the actual situation, that is, the twist number twisted, can guarantee production under the premise of twist Number should not excessively, i.e. the revolving speed of twisting rotation axis is unsuitable excessively high.According to the requirement of grid specification fill yarn ends, by used latitude Yarn yarn group is placed on twister, and rove is introduced on the Weft laying trolley of tricot machine by export path, and starting tricot machine is " slow Vehicle " driving button, when twisting mills and tricot machine being waited to cooperate no problem, normal boot-strap produces again.The booting of tricot machine and twisting mill Be it is synchronous, when tricot machine opens " slow train ", twisting mill, which is in, to slowly run, it is normal after tricot machine open high speed twisting mill Open high speed automatically therewith, tricot machine stops, twisting mill is also simultaneously stopped rotation.The reciprocating motion of Weft laying trolley of warp knitting machine, drawing Basalt rove is constantly from unwinding output outward in yarn group, and during unwinding output, rove leans on the high speed rotation pair of yarn group The rove unwound out is twisted, and the twisting of basalt rove, unwinding, the process for spreading latitude is completed, to realize basalt lattice The production of grid.

The production technology of basalt protofilament rove parallel with precursor and close technique, determine basalt rove yarn beam The precursor tension without cohesive force, composition rove is inconsistent between dispersed strong and conjunction protofilament, is tensioned Shi Youyuan in rove The phenomenon that silk is still in relaxed state, makes tricot machine in the binding area of warp and weft, the binding needle to run at high speed can not be to whole Weft yarn is bundled, so as to cause that can not produce.Basalt fibre rove is making weft yarn in use, will mention for woven fabric at present Before twisted, to improve the cohesive force between rove precursor, when meeting weft yarn moment high-speed cruising because tension it is inconsistent caused by Rove plays filoplume；Or avoid tricot machine that from cannot all bundling latitude because part precursor is loose in rove, bundlees crochet hook when producing grid The problem of yarn.Basalt rove is having many drawbacks using preceding specially twisting: first is that the machine equipment of twisting thread of large package is put into, because For the rove for basalt grid, generally all weigh 2.4 kilograms in 2400tex(1 km) left and right, only with big twisting machine, The spool of large package could accommodate more rove, buy twisting machine and production needs to put into a large amount of human and material resources；Second is that twisting The basalt twisted on line machine spool is thick, cannot directly do weft yarn use, and does latitude again after having to pass through winder network resultant yarn group Yarn uses (the spool both ends of twisting mill are not able to satisfy the high-speed unwinding of weft yarn moment with plug).When on spool When rove becomes yarn group, because the modulus of basalt fibre is big, i.e. rigidity is big, so causing very big unexpected damage again to fiber Wound.Basalt rove is specially twisted using preceding, although solving the problems, such as precursor cohesive force in rove, also band simultaneously The unfavorable factor of production efficiency and product quality to influence.Third is that the spool of a large package capacity can only also accommodate 5 kilograms The rove of left and right, and basalt yarn group weighs 20 kilograms, a large yarn group be not intended to be divided into twisting process 4 spools, Generate four connectors.Non junction in large yarn group, and there have been 4 tieing for spool, artificially cause when connector increases, uses Machine stop times increase.Calculated by 12 paving latitude rove, with large yarn after line twist immediately and is twisted using rove network at yarn group It compares, it is assumed that yarn group calculates all based on 20 kilograms of weight, and online twisting immediately, which has used one yarn to roll into a ball machine stop times, will lack nearly 50 It is secondary, so having seriously affected production efficiency using the yarn group after twisting doff.

Basalt grid compared with glass fiber grid in performance with greater advantage, especially in extreme environment and special Application, play even more important effect, be that glass fiber grid is irreplaceable.So with the development of society, profound The application field of military rock grid can increasingly wider, dosage also can be increasing.The increase of basalt grid dosage it may first have to solve Certainly the problem of basalt grid difficult processing, i.e., how under the premise of guaranteeing quality, improve production efficiency.And basalt grid is raw Produce the raising of efficiency, it is important to precursor obvolvent in rove after solving the problems, such as basalt rove and closing.Precursor obvolvent in rove Power is good, forms the tension of rove precursor with regard to consistent, convenient for the high-speed production of basalt grid, otherwise just influences basalt grid Production efficiency and product quality.There are three the approach for solving basalt rove cohesive force: one is by changing basalt fibre Rove production technology, the cohesive force to change basalt rove, just as the production technology of the direct yarn of glass fibre, in wire drawing The rove number (tex number) that technique requirement is disposably completed on machine, the plying process for being no longer pass through precursor and closing, but the current Black Warrior The production technology of rock fiber is unable to reach this requirement.Second of approach is when basalt rove is used as weft yarn to weave grid When, twisting processing is carried out during use, to increase the cohesive force in plying rove between precursor, that is, it is originally practical new The online instant twisting method of type.The third is method used at present, is carried out using the preceding basalt rove to after plying Twisting, to improve the cohesive force between precursor.In these three approach, only second of approach be the most reality, operation most Convenient and effect is best.In the production process of basalt grid, it is used as the basalt rove that weft yarn uses, using spreading It is twisted during latitude, i.e., spreads latitude in twisting and have many good qualities.The first, reduce the process twisted in advance together, to reduce The investment of equipment and manpower, reduces production cost；The second, it avoids caused by twisting artificially in advance to basalt rove Problem more than damage and connector, to ensure that the quality and production efficiency of final grid finished product；Third reduces operation Difficulty, improve product row yielding.The premise of basalt grid large area implementation is exactly to solve basalt grid weft yarn rove After middle precursor and conjunction the problem of cohesive force, and solving cohesive force best bet is exactly to twist to basalt rove, is passed through Mutual between protofilament tangles and mutual extrusion, is integrally formed precursor that is all parallel and closing, furtherly to profound Military rock weft yarn twisting most efficient method is exactly to twist during grid production, paving latitude, i.e. online production is twisted (only immediately Weft yarn is twisted, because weft yarn its instantaneous speed during back and forth paving latitude changes very greatly :-zero-high speed-zero of high speed Velocity variations.The movement of warp thread be at the uniform velocity, use so not having to twisting), here it is the purpose of this utility model and crucial institute In.

Yarn is twisted using twisting machine, is very common technique, the yarn no matter twisted is thick or thin, and principle is all The same, the yarn being twisted at the uniform velocity is unwound from yarn group and is come out, is transported to by certain speed by the tractive force of roller In company with the high-speed rotating spool of spindle, spool twists in high speed rotation, while the yarn after twisting is wrapped on spool.Its principle It is that the rotation drive of spindle is twisted the rotation of yarn, by Yarn twisting, and the yarn after twisting is wrapped on spool.And this Utility model to the principle doing basalt rove twist principle that grid weft yarn uses and twisting machine and being twisted to yarn just On the contrary.By the traction force of Weft laying trolley of warp knitting machine, according to certain speed (speed for completing primary paving latitude), by basalt rove From yarn, group is pulled out, and yarn rolls into a ball rove while being pulled power drawing unwinding, and entire yarn group twists rotation axis in high speed rotation Driving under, by setting speed high speed rotation twist, i.e., basalt rove while from yarn group on unwind while twisted.This is practical new Type is the high speed rotation rolled into a ball by yarn, the twisting to rove is completed, to realize basalt grid weft yarn in use Online instant twisting, this be the utility model twisting equipment basic principle and thinking.

Rotation axis is twisted, is the core component of basalt rove twisting, is equivalent to the spindle of spinning machine.Due to a Black Warrior The weight of rock yarn group will be in 20kg or more, and yarn group will be in the next superhigh speed operating of drive of twisting rotation axis, so will The stability for asking twisting rotation axis to have high intensity and run at high speed, will give from material and machining accuracy and guarantee.Basalt Yarn group be put into twisting rotation axis be it is directive, the direction of rove unwinding and twisting rotation rotational axis direction are necessary identical.Each Rotation axis is twisted all by a motor by V -- belt Drive, each motor is by a Frequency Converter Control, general supply and host " slow train ", " express " switch button of (tricot machine) are connected, and are controlled together by host.The size for twisting the twist, can be according to production Actual conditions determine, are produced as standard to meet machine normal boot-strap, and turning for yarn group is adjusted by adjusting the frequency converter of motor Speed is realized.Rove is during with the yarn group unwinding to run at high speed, due to the effect of circular motion centrifugal force, because of rove weight It is larger, it will form very big yarn circle.Rove output all cannot proceed normally after the formation of yarn circle will lead to the rotation of yarn group and twisting, So device-yarn circle protector that yarn circle is formed when yarn rolls into a ball the centre of height hereinafter, devising prevention yarn group's high speed rotation, It prevents the effect because of yarn group high-speed rotation centrifugal force to be formed by yarn circle, ensure that rove is twisted and what is unwound is normally carried out. When rove unwinding yarn group top when, tie up be attached to yarn group surface yarn circle protector just do not have effect, so in yarn cluster centre The surface of (rotation axis center) devises cone shield screen covering, the rove yarn circle after twisting is gradually collapsed, by shield screen covering The output of tapered tip porcelain eye hole completes the design objective unwound to rove in twisting.So through protecting screen covering top after twisting The basalt rove of porcelain eye output, moves vertically after 1.5 meters upwards along porcelain eye direction, then respectively passes through a porcelain eye and change rove The direction of motion, rove enters the Weft laying trolley of tricot machine.It by the effect of each design organization and is mutually linked, realizes the Black Warrior (rove after twisting is thick to 1.5 meters vertically upward to the function of twisting paving latitude to weft yarn to rock grid immediately online in process of production The twisting area of yarn, rove will rotation axis be axially vertical moves upwards along twisting, and the twisting and output, reduction for being conducive to rove are to thick The damage of yarn).

2. rack section；8 groups of twisting rotation axis are divided into the two sides that 2 straightened portions are mounted on rack, 4 groups of every side, and every two groups Between distance of shaft centers be 800mm(general basalt yarn group specification are as follows: height 260mm, 250~300mm of diameter, diameter of bore 75mm).The size of rack are as follows: long * wide * high=3200*1800*600, motor are mounted on the following crossbeam of frame central, belt Disk is downward and the belt pulley of twisting rotation axis is in same level.Each twisting rotation axis has a motor to drive.In machine In rack beside frame two sides, every twisting rotation axis, it is all respectively provided with shield screen covering and yarn circle protector, prevents yarn group high speed from turning Influence of the looping that effect rove when dynamic because of centrifugal force is formed to twisting.

3. protecting screen covering.One shield screen covering is installed in the surface of each twisting rotation axis basalt yarn group, shield screen covering is in circle Cone cell is equipped with porcelain eye on vertebra point, is exported after the twisting of basalt rove by porcelain eye.Shield screen covering is made into stainless steel plate, inside Want smooth, seam cannot hang yarn.Shield screen covering has rocking lever to be fixed by vertical rocker arm fixed link, and rocking lever is rectangular in shape, and erects on one side Straight cutting enters in rocker arm fixed link, and another side rocker arm horizon bar is connected with shield screen covering conical points below porcelain eye.Rocker arm horizon bar will protect Screen covering is vertically hung in the surface of twisting rotation axis, and the yarn group of one third height is covered.Shaking in insertion rocker arm fixed link Arm vertical bar can be extracted out and be able to rotate from fixed rod tube.It, can be by rocker arm when basalt yarn group needs replacing or when handling failure The basalt yarn group protected under screen covering is exposed and carries out changing yarn or troubleshooting, after being disposed again by vertical bar extraction, turn away By shield homing.When rocking lever is in the working condition right above yarn group, have one between rocker arm fixed link and rocking lever Positioning pin fixes shield screen covering, it is ensured that high speed rotation twisting, the rove unwound shroud in shield screen covering.

4. yarn circle protector；Yarn circle protective device-yarn circle protection is housed below the centre that the basalt yarn of rotation is rolled into a ball Device, the formation of yarn circle when prevention yarn rolls into a ball high-speed rotation.Yarn circle protector is that have two horizontal reinforcements and a vertical annulus and not The rectangular frame that the steel plate surface that becomes rusty forms, casing are mounted on the pedestal on the outside of rocker arm bottom of fixed, by torque spring to yarn Enclose the certain torsion of protector, include yarn circle protector be fixed on pedestal swivel mount on the outside of rocker arm bottom of fixed, Drive vertical direction frame reverse in the horizontal plane, by be mounted on the rectangular frame other end, with certain arc not Rust steel plate tightly sticks on the outside (can not disengage when yarn rolls into a ball high speed rotation) of yarn group, the basalt for unwinding high speed rotation Rove is under the action of the shield yarn stainless steel plate tightly sticked, because the coil that high speed rotation centrifugal force is formed is deteriorated, rove It is tightly sticked on surface, side that yarn is rolled into a ball to be twisted, while exporting from the porcelain eye hole on taper shield screen covering top.

Certainly, above description is also not limited to the example above, and technical characteristic of the utility model without description can lead to It crosses or realizes that details are not described herein using the prior art；Above embodiments and attached drawing are merely to illustrate the technology of the utility model Scheme is not limitations of the present invention, and the utility model is described in detail referring to preferred embodiment, this Field it is to be appreciated by one skilled in the art that those skilled in the art institute in the essential scope of the utility model The variations, modifications, additions or substitutions made without departure from the objective of the utility model, want by the right that also should belong to the utility model Seek protection scope.
