Description
Technical field
The utility model relates to a kind of double rib warp loom, specifically is meant the knitting mechanism of double rib warp loom.
Background technology
The knitting mechanism of existing double rib warp loom comprises needle-bar, is fixedly mounted on latch needles, latch needles motion, the comb arrangement that sley point is installed, sinker and knocking-over bar on this needle-bar.Weaving the lopping campaign in other words of moving is to be cooperatively interacted to move by latch needles, sinker and sley point etc. to finish.But there is following shortcoming in this knitting mechanism, at first, because latch needles is thicker, and makes more complicated, thereby makes the plane No. of its adaptation lower; Secondly, because latch needles is to rely on old coil to open and close needle latch up and down, this just makes yarn produce bigger tension force, and when particularly remaining silent, necessary spread loop makes its broad position of overlapping pin, and the tension force that makes yarn produce like this is bigger; In addition, because of when needle latch is closed, yarn can not be encased inside the pin mouth once more, easily causes the yarn slippage of having filled up, thereby the difficulty of starting; And on-streamly also need to install additional the self-closing steel wire of needle latch for preventing that the backwash of needle latch from closing, but as steel wire install improperly, it is much unfavorable then can to bring, as the damage needle latch, cause dropped stitch etc.; Once more, because the required traverse of latch needles braiding motion is bigger, thereby machine speed is lower.
The utility model content
It is less and can adapt to the knitting mechanism of the double rib warp loom of higher plane No. that the technical problems to be solved in the utility model provides a kind of tension force that can be used at a high speed and be difficult for producing dropped stitch or wrong pad yarn, yarn when braiding.
For solving the problems of the technologies described above, the utility model adopts the knitting mechanism of so a kind of double rib warp loom, comprise needle-bar, be fixedly mounted on knitting needle, the needle motion on this needle-bar, the comb arrangement that sley point is installed and knocking over parts, described knitting needle is a groove pin, this knitting mechanism also comprises nook closing member, nook closing member bed and the movement of slide mechanism that can do slip relatively in described groove pin needle tray, and described nook closing member is fixedly mounted on the upper end of nook closing member bed.
Described movement of slide mechanism comprises conjugate cam, lower link, swing arm, goes up connecting rod and little axle; One end of described lower link and the roller carriage of conjugate cam are hinged, and the other end and described swing arm are hinged; One end and the swing arm of described upward connecting rod are hinged, and an end of the other end and described little axle is hinged; The other end of little axle is fixedly connected on the bottom of described nook closing member bed; Offer through hole on the described needle-bar, described little axle passes this through hole and needle-bar is slidingly matched; Described swing arm is sleeved on the balance staff of described warp knitting machine.
After adopting such structure, because knitting needle adopts groove pin, and groove pin is thin, required traverse is less during the braiding motion, and it is few to need not heavy pressing plate, power consumption when installing, thereby can be used for braiding at a high speed; In addition, the rigidity of groove pin is bigger, thereby is difficult for producing dropped stitch or wrong pad yarn when weaving at a high speed, again since when braiding yarn be with very low tension force operation, thereby less to the friction of knitting element, prolonged service life of parts such as groove pin; Owing in knitting mechanism, installed nook closing member, nook closing member bed and movement of slide mechanism additional with the groove pin routing motion, and nook closing member can be removed the impurity in the groove pin needle tray when sliding, and because groove pin is thinner, thereby can adopt staple fibre yarn, blended yarn and stretch yarn etc. to weave, and can produce hyperfine fabric, therefore can adapt to higher plane No..
As further improvement of the utility model, between described little axle and needle-bar through hole, also be provided with a fairlead that is fixedly mounted in this through hole, described little axle is slidingly matched by this fairlead and needle-bar.Adopt such structure, can prevent that little axle from directly contacting with needle-bar, thereby prolong the service life of needle-bar greatly.
As another kind of improvement the of the present utility model, on described swing arm, also be provided with at least one and be used to change installing hole with the lower link articulated position.Adopt such structure, be convenient to regulate the nook closing member movement position, it is cooperated better with groove pin.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is a kind of structural representation of the utility model double rib warp loom knitting mechanism.
Fig. 2 is a kind of structural representation of movement of slide mechanism in the utility model.
The specific embodiment
Knitting mechanism referring to a kind of double rib warp loom shown in Figure 1, comprise needle-bar 1, be fixedly mounted on the groove pin 2 on this needle-bar 1, the comb arrangement 3 that sley point 3-1 is installed and knocking over parts 4, this knitting mechanism also comprises nook closing member 5, nook closing member bed 6 and the movement of slide mechanism 7 that can do slip relatively in described groove pin needle tray, and described nook closing member 5 is fixedly mounted on the upper end of nook closing member bed 6.Groove pin motion not shown in the figures, it can adopt former latch needles motion.Described knocking over parts 4 can adopt knocking-over bar, also can be made of knocking over needle-bar and knocking over pin.
As shown in Figure 2, described movement of slide mechanism 7 comprises conjugate cam 7-1, lower link 7-2, swing arm 7-3, goes up connecting rod 7-4 and little axle 7-5; The end of described lower link 7-2 and the roller carriage 7-1-1 of conjugate cam 7-1 are hinged, and the other end and described swing arm 7-3 are hinged; An end and the swing arm 7-3 of described upward connecting rod 7-4 are hinged, and the end of the other end and described little axle 7-5 is hinged; The other end of little axle 7-5 is fixedly connected on the bottom of described nook closing member bed 6; Offer through hole 1-1 on the described needle-bar 1, described little axle 7-5 passes this through hole 1-1 and needle-bar 1 is slidingly matched; Described swing arm 7-3 is sleeved on the balance staff 8 of described warp knitting machine frame 9.
When preventing that little axle 7-5 from moving up and down in through hole 1-1, needle-bar 1 is caused bigger wearing and tearing, shorten the service life of needle-bar 1, the utility model is provided with a fairlead 1-2 who is fixedly mounted in this through hole 1-1 between described little axle 7-5 and through hole 1-1, little axle 7-5 passes the endoporus of this fairlead 1-2 and is slidingly matched with it, when maintenance, only need to change fairlead 1-2 and get final product like this.
Referring to Fig. 2, the movement of slide process is as follows: the rotating drive lower link 7-2 by conjugate cam 7-1 moves up and down, moving up and down of lower link 7-2 makes swing arm 7-3 rotate around balance staff 8, thereby connecting rod 7-4 and little axle 7-5 move up and down in the driving, because little axle 7-5 is fixedly connected on the bottom of nook closing member bed 6, thereby make the nook closing member 5 that is fixedly mounted on nook closing member bed 6 upper ends in the groove pin needle tray, do to slide relatively.
For nook closing member can be cooperated better with groove pin, on described swing arm 7-3, also be provided with at least one and be used to change installing hole 7-3-1 with lower link 7-2 articulated position.
