Description

Needle cylinder periphery displacement circular warp-knitting machine

The utility model is a kind of cylinder type warp knitting machine of novelty.This machine can weave the knitted fabric of polychrome spirality decorative pattern.

In the prior art, the knitted fabric of spirality decorative pattern be by the cylindrical shape weft machine by increasing the inclination angle that the system for weaving number enlarges cross-over style on the fabric, the braiding of spirality ground.But the increase of system for weaving number is subjected to knitting needle and the triangle impulsive force forms keeping within bounds of resistance, thereby the helix angle of woven designs is little.In order to reduce to weave resistance, enlarge the woven designs helix angle, Russian Patent SUP 506,200 provides a kind of single-needle circle latitude machine.This machine has five needle tracks, and the knitting needle of five kinds of differing heights Zhen Chung is cycle arrangement successively, and the needle track frame is subjected to cam control lifting, be rotatably assorted with syringe, make knitting needle by certain track operation, the knitting position of adjacent needle track differs a needle gage, thereby forms the braid method of per five needle gages one tunnel.The helix angle of its fabric construction had enlarged some than in the past.In common cylinder type warp knitting machine, syringe does not rotate, and sley bar comes back rotation, does not form spiral woven.In the Buddhist nun's warp knitting machine of Milan, syringe does not rotate, and two two-way relatively rotating of sley bar form oblique tartan effect, even this machine can convert the warp knitting machine of similar spiral woven to through changing, but need have with the thread-carrier rotation through axle, mechanism is inevitable very complicated.

The purpose of this utility model is to provide a kind of simple in structure, braiding circular knitting machine that resistance is little, fabric line inclination angle is big, with braiding polychrome spiral pattern, have concurrently through compiling and the knitted fabric of weft-knitted characteristic.

To achieve these goals, the utility model adopts that a kind of thread-carrier is fixed, syringe is around the cylindrical shape warp knitting machine of its circle core shaft displacement.This machine is made up of feed carrier, knitting mechanism, draw-off mechanism and transmission mechanism.Feed carrier of the present utility model comprises a yarn guiding disk that is fixed on the annular on the frame, is fixed on the frame, and its position is above syringe, and is concentric with syringe.Its diameter is greater than syringe.Have thread guide eyelet equably along the yarn guiding disk circumference, the number of thread guide eyelet is corresponding with knitting needle on the syringe.The yarn of drawing from side creel penetrates thread guide eyelet through tension pulley, feeds knitting needle again.Knitting mechanism of the present utility model comprises the knitting needle on a syringe and the syringe.Outer wall circumference along syringe has needle tray equably, and the knitting needle of needle tray interpolation is a latch needles.The number of latch needles is pressed the barrel dliameter of syringe and plane No. and is decided.Syringe can be around its central shaft one-directional rotation, and the pin Chung of all latch needles is endured dials by one and connects together, simultaneously along the needle tray lifting.Draw-off mechanism of the present utility model comprises a pair of roller roller, and there is ridge design on the surface of roller roller, and coefficient of friction is higher.Transmission mechanism of the present utility model is to divide three tunnel transmissions by main shaft.The rotation of first control syringe, main shaft is by one group of gear mechanism, and needle cylinder is rotated to a direction.It two is control latch needles liftings, and main shaft is by toggle and the sliding bar mechanism that links to each other, drives to be positioned to endure the lifting of punch block drive knitting needle around the syringe.It three is that control tractive roller roller rotates, main shaft by the gear mechanism transmission it.Satisfy the weaving requirement in order to ensure above-mentioned three's action, a batch (-type) worm screw respectively is housed in syringe gear mechanism and pulling roll gear mechanism, the angle of its work is 150 °～210 °, and syringe and pulling roll are rotated once at each braiding intercycle with having a rest.The installation phase difference of two batch (-type) worm screws is 120 °～240 °, makes that syringe stops operating when knitting needle rises, and pulling roll turns over the distance of an about line; When knitting needle descended, syringe turned over one, two, three or four needle gage, and pulling roll stops operating.In transmission mechanism, some gears in the gear train of control syringe rotation can be changed by the needle gage of syringe circumferential displacement in each braiding circulation, change the gearratio of this gear train.

Operation principle of the present utility model is as follows:

The utility model utilizes latch needles braiding lopping, adopts the very big spiral pattern knitted fabric in principle braiding line inclination angle of the last needle gage one tunnel of weft knitting.In each braiding circulation, all knitting needles all weave a coil, turn over a needle gage with syringe then, remake next braiding circulation, thereby realize the braiding of a needle gage one tunnel.The latch needles lifting once in each braiding circulation, latch needles rises from minimum point, old coil encloses to shank from moving back in the pinhock because of being subjected to the traction force effect, open needle latch thus, this moment adjacent about two needle gages of old coil at syringe ability to speak place with its thread guide eyelet, formed oblique line is just in time pushed down the needle latch of opening on the rising knitting needle, prevented the needle latch backwash, the syringe band knitting needle and old coil turns over a needle gage to the direction away from thread-carrier when latch needles descends, make between thread guide eyelet and old coil at a distance of about three needle gages, and with latch needles at a distance of about two needle gages, the oblique line between thread guide eyelet and old coil is satisfied like this fills up the yarn requirement.Latch needles descends and to hook up this yarn, by old coil remain silent, lasso, knocking over, latch needles be yarn kinking, the lopping of hooking, and grips old coil by the syringe ability to speak.The pinhock top drops to the length of the following distance decision new coil of syringe mouth.This moment, new coil linked to each other with oblique line with thread guide eyelet, and its distance is got back to about two needle gages again.Circulate with this, just as the braiding of a needle gage one tunnel on the circle latitude machine, braiding spirality pattern fabric.When syringe in each braiding circulation, when its center of circle displacement was two, three or four needle gages, thread guide eyelet correspondingly was one to entry every three every two or one every one, one, its lopping principle is also identical, but has changed the inclination angle of the spiral pattern of braided fabric.

The utlity model has following advantage:

1, realized mostly being most in the similar weft knitting multichannel braiding of a needle gage one tunnel.

2, can knit out the knitted fabric of polychrome spirality decorative pattern.

3, its knitted fabric has concurrently through compiling and weft-knitted characteristic.

4, mechanism is fairly simple.
