A kind of three-dimensional tubular loom of the utility model, woven three-dimensional tubular fabric is as shown in figure 16, justifies with conventional three-dimensional
Loom is different, and the loom of the utility model design does not have shedding mechanism, and relies on and vertical yarn pre-soaked resin is solidified into certain
Rigid yarn rod is open to be formed.Weaving starts the preceding rigid fibre rod by some equal lengths by pre-designed fabric knot
Structure is arranged in annular.Circumferential yarn and radial direction yarn alternately feed the gap of rigid fibre rod.After weaving starts, circumferential yarn is solid
Fixed position is introduced in the circular passage that vertical yarn is formed.Radial direction yarn then by radial direction knotting mechanism 8 by vertical yarn bondage into knot.With
It is constantly urgent the yarn helix layer weaved while the woven fabric formed constantly rotates along axle.Most end form
Into the fabric for completing densification.Forming process is broadly divided into three steps：
(1) production of axial bar：The pre- impregnation of glass fibre is heated and cured into the composite of glass fibre and phenolic aldehyde, into
To there is the rigid bar of favorable elasticity.And the yarn diameter for twisting with the fingers solidification should reach requirement of the fabric to the yarn that hangs down.Strict control bar
Diameter and quality.
(2) installation of axial bar：Using manual or semi-automatic drawing-in machine all axial bars (vertical yarn) according to fabric
Stitch technique requirement, is fixed on design attitude.
(3) introducing of circumferential yarn and radial direction yarn with into knot：Circumferential yarn and radial direction yarn are backed off from tube, through tensioner shape
Into after stable tension force, introduced from fell, chain coil is formed by the knotting mechanism 8 being radially arranged.
From the weaving principle of three-dimensional tubular fabric, three-dimensional tubular loom mainly realizes three motions, is radially respectively
Diametrically reciprocating for knotting mechanism is moved with the intermittent rotary of rotating mechanism, and the axial movement of urgent mechanism.It is main logical
This radial direction knotting mechanism, rotating mechanism, urgent mechanism and diameter changing mechanism are crossed to realize.
A kind of three-dimensional tubular loom of the utility model, three-dimensional woven is carried out by three groups of yarns, respectively hang down yarn, circumference
Yarn, radial direction yarn.It is fixed between arc 6-8 and gear c11-1, and arranges continuous in a ring in axial yarn before weaving starts
It is uniformly distributed.With motor b9-1 startup, rotating mechanism A10 and rotating mechanism B11 are rotated with constant speed.Circumferential yarn exists
Fixed weaving plane is introduced into from socket (not shown), in the concentric circular channel that axially yarn is formed, is laid and is referred in a circle
On shape cramp 5-7.Due to rotating mechanism A10 and rotating mechanism B11 effect, final circumferential yarn can form flat herein in a ring
The circumferential yarn helix layer without tension force.Radial direction yarn is after fixed weaving plane is introduced into, in woven generation point, shank
Chain type rings of the knitting needle 8-19 by weft-knitted lopping method the knotting closing of radial direction yarn on 8-18, surround the radial direction spiral shell of axial yarn composition
Revolve thread layers.This thread layers is located between axial yarn and the circumferential thread layers continuously fallen.When yarn helix layer forms fabric,
The circumference and radial direction thread layers of finger-like cramp 5-7 urgent new formation downwards, edge on grooved ring b10-4 is overlayed by urgent thread layers
Axial yarn to move gradually downward.Knotting mechanism 8 mainly is responsible for that radial direction yarn is knotted into chain ring and bundled with chain type lopping method to hang down
Yarn.
The motion principle of knotting mechanism 8 is：The yarn that hung down before weaving starts is first good by circular arrangement, and is fixed in grooved ring
On c11-4, the initiating terminal of circumferential yarn is fixed in the gap of vertical yarn.With the progress of weaving process, disk constantly rotates, week
Constantly backed off to yarn from creel.It is introduced in the circular passage of vertical yarn arrangement form, is wrapped on vertical yarn in fell, radially
Yarn then with knitting needle 8-19 radial motion hang down yarn circumferential movement, constantly formed yarn ring.
Knotting process is broadly divided into following process.
(a) draw pin, circle process is moved back, referring to Figure 17 (a)：
This process is the end time of upper one circulation, i.e., the initial time newly circulated, now knitting needle is farthest from radial direction yarn, and
Start close to radial direction yarn.During this, the old coil under crochet hook can be fallen back on the shank under needle latch.Due to yarn and the line of hanging down
The resistance formed is enclosed, the movable lug originally closed on crotch is opened.Pinhock is facilitated to catch on new yarn.
(b) yarn hook process, referring to Figure 17 (b)：
As latch needles moves forward, the front end of latch needles can contact with radial direction yarn.Now knitting needle and radial direction yarn are apart from most
Closely.Because radial direction yarn is limited at the horizontal plane of slightly below latch needles, and the front end of latch needles is in spindle.Radial direction yarn connects with latch needles
After touch, certain pressure can be produced, continues to move with latch needles, this pressure can be pressed into radial direction yarn into crotch, such latch needles
Smoothly catch on new radial direction yarn.
(c) kinking process, referring to Figure 17 (c)：
Direction can be changed by catching on the latch needles of radial direction yarn, be moved to the direction away from radial direction, the new yarn for touching pinhock
Bend lopping.When continuing motion, due to the resistance of lasso, originally movable lug in opened condition can be closed on crotch, prevented curved
Hook catches on old coil.
(d) knocking over, knitting cycle, referring to Figure 17 (d)：
As knitting needle 8-19 continues to take off and be enclosed on new coil from syringe needle away from radial direction yarn, old coil, at the same time
Rotating mechanism A10 and rotating mechanism B11, the distance of a stitching is rotated, new coil is reached defined size, and new is hung down
Yarn is sent into fell, and subsequent rotating mechanism A10 and rotating mechanism B11 remains stationaries, needle motion is to from radial direction yarn maximum distance.
Generate a circulation by this above-mentioned (a), (b), (c), (d) 4 processes, each circulation will bundle one group it is new
Vertical yarn.Due to hanging down, yarn is doing circumferential movement, and after vertical yarn rotates a circle along main shaft, the every group of yarn that hangs down can all be lived by bondage.It is this
Chain type lopping method can produce one layer of endless yarn layer, so complete the shaping of one layer of fabric.After one layer of weaving is completed, hang down
Yarn can decline corresponding height vertically, and this stylish one layer weaving will start.So circulation, final circumferential yarn and radial direction yarn are formed
Chain ring can twist bondage live hang down yarn, form complete fabric.
Knotting mechanism 8 except with rotating mechanism A10 and rotating mechanism B11 it is interrelated in addition to, also simultaneously need to be with diameter changing mechanism 6
Coordinate.When weaving the variable cross-section products such as coniform fabric, knotting mechanism 8 also need to be with the change of product diameter, the bottom of knotting mechanism 8
The chute 8-5 in portion makees to move radially accordingly with slide rail b weaving planes.The control of the motion process of knotting mechanism 8 is by motor
A7-2 is controlled, and motor a7-2 sends power to main shaft b8-7 by synchronous cog belt b8-10, and main shaft b8-7 passes through conical gear
C8-4 and conical gear d8-6, leading screw c8-3 is driven to rotate, leading screw c8-3 is connected by feed screw nut with support plate b8-2, and with
Base 8-1 moves back and forth on slide rail b, and while conical gear g8-23 engages with conical gear h8-24, conical gear
G8-23 can carry out axial displacement along splined shaft b8-21, therefore ensure that knotting mechanism 8 does not influence to move while radial displacement is done
Power is transmitted.
Rotating mechanism A10 and rotating mechanism B11 is also one of core institution of loom.Its main function is feeding.As
Coordinate being smoothed out for radial direction knotting mechanism chain type lopping method, in weaving process, when the smooth bondages of knitting needle 8-19 live one group
, it is necessary to which rotating mechanism A10 and rotating mechanism B11 rotates the angle of a stitching during vertical yarn, the vertical yarn that new non-bondage is lived is sent
Enter fell, carry out lopping.Simultaneously when the yarn weaving of one layer of circular section is completed, it is also desirable to by yarn it is urgent after decline vertically
One pitch height, in favor of the weaving of next layer of yarn.In addition yarn is urgent also by needing rotating mechanism A10 and rotating mechanism
B11 cooperation.
After one layer of new circumferential yarn is formed with radial direction yarn, it can be laid in loose form on old thread layers.In order to
Form the compact fabric of institutional framework, it is necessary to apply in new thread layers axially downward stablize urgent power.This process by
Urgent mechanism 5 realizes.
Finger-like cramp 5-7 in urgent mechanism 5 is in weaving, and in addition to it can make axial yarn and keep neat spacing, it is also
The thread layers slide downward being stacked on double layer support plate that can make to weave, and it is urgent.Finger-like cramp 5-7 is distributed in grooved ring b10-4
On rotated together around leading screw a3 and the fabric that weaves.Finger-like cramp 5-7 is leaned against on first layer yarn, and they are pressed downward
(second layer yarn at the same time newly woven can be covered on finger-like cramp 5-7).When they run into circular arc rail in gap regions
During a5-12 and circular arc rail b5-13, finger-like cramp 5-7 can be lifted and retract at circular arc rail a5-12 and arc orbit b5-13.
Therefore they have broken away from the second layer yarn woven being pressed on them, and back-pressure is on it, in order to and it is double-deck
Supporting plate, which coordinates, moves downward thread layers.So repeatedly, per warp layer line layer is newly woven, finger-like cramp 5-7 pushes with regard to urgent
Warp layer line layer.
In order that finger-like cramp 5-7 constantly keeps more constant urgent power, one is additionally provided with grooved ring a5-5
Fixed horizontal pressure force plate cover plate a5-8, to limit finger-like button 5-7 pieces on a constant horizontal line and make finger-like cramp 5-7
The yarn being woven into is controlled under a suitable pressure.By keeping double layer support plate in each circulation relative to solid
It is identical in the height that thickness direction is compacted with thread layers to allocate the height of face decline, then the constant urgent power of fabric acquisition.
In order to strengthen the ability of Product flexible manufacturing, loom is set to possess the ability for producing a variety of series of products, you can production
Different-diameter, changing cross-section fabric of different shapes.Loom needs diameter changing mechanism to control fabric diameter of section in real time.Diameter changing mechanism
6 are broadly divided into two parts, and Part I is responsible for controlling knotting mechanism to carry out radial displacement, and Part II is responsible for controlling vertical yarn yarn
The radial displacement of rod.Wherein Part II is controlled by motor a7-2 and moved, and after motor a7-2 is rotated, passes through synchronous cog belt a4
Reach at the belt wheel a6-2 of each diameter changing mechanism, belt wheel a6-2 drives conical gear a6-3 and conical gear b6-4 to rotate, circular cone tooth
Take turns b6-4 belt wheel leading screws b6-5 to rotate, the slide plate 6-6 on leading screw b6-5 moves radially along leading screw b6-5, and stock 6-7 is with cunning
Plate 6-6 is moved and is driven arc 6-8 to do radial motion in grooved ring a5-5 inner ring, and arc 6-8 is promoted and rested on thereon
Hang down yarn yarn rod, makes yarn bending of hanging down, thus changes the tubular fabric diameter that yarn is surrounded that hangs down, to realize reducing purpose.
