Abstract
The utility model relates to a stitch-forming mechanism of double-needle bar warp knitting machine comprising a needle bed, a knitting needle, a needle bed connecting rod, a swing arm, a swing axis, a drive linkage, a mid-swing arm, a mid-swing axis and an eccentric driving mechanism. The needle bed connecting rod through the upper swing link and the lower swing link is connected with the swing arm to construct a four-bar linkage mechanism. The utility model has the advantages of that it realizes up-and-down movement of the needle bed through cycloidal motion of the upper-and-lower swing links to raise operating speed and mechanical efficiency of the mechanism greatly and to reduce noise, and the fulcrum of the swing arm for the needle bed moving is arranged on the swing arm which is provided with knocking-over bars, therefore relative position between the needle bed and the knocking-over bars keeps basically unchanged when the distance between the needle bed and the two knocking-over bars is regulated.
Description
Technical field
The utility model relates to the double rib warp loom field, particularly a kind of double rib warp loom looping mechanism.
Background technology
Needle-bar need move up and down and finish the lopping of yarn in double rib warp loom.The control of needle-bar movement position at present is to use ball ball-collecting rack guide pillar, guide pin bushing structure, and ball driving ball-collecting rack moves together when the ball guide pillar moves, and ball is attached to sizable frictional force on the ball ball-collecting rack.Because ball is numerous, the frictional force that produces during high-speed motion is also bigger, is unfavorable at a high speed, and produces bigger noise.Adjusting fabric thickness dependence knocking-over bar simultaneously is the center swing offset with the balance staff, the leading section of knocking-over bar produces deviation with respect to the leading section of knitting needle in stroke directions, so need revise to this, carry out adjustment, the change of needle stroke, make the change operation of knocking-over bar become complicated.
Summary of the invention
For overcoming the deficiency of existing double rib warp loom looping mechanism, the purpose of this utility model provides a kind of double rib warp loom looping mechanism, oscillating motion with connecting rod realizes moving up and down of needle-bar, need not to carry out the adjustment of needle stroke after the change knocking-over bar spacing.The technical scheme that its technical problem that solves the utility model adopts is: a kind of double rib warp loom looping mechanism, has needle-bar, the needle-bar connecting rod, swing arm, drive link, middle swing arm, middle balance staff, balance staff, eccentric drive mechanism, needle-bar and knitting needle are installed on the needle-bar connecting rod, swing arm and middle swing arm are installed on balance staff and the middle balance staff, balance staff and middle balance staff are installed on the frame, middle swing arm and eccentric drive mechanism, drive link one end flexibly connects, the other end of drive link is connected with the needle-bar connecting rod, and described needle-bar connecting rod is by upper pendulum bar and draft link and swing arm formation four-bar linkage structure.
The beneficial effects of the utility model are, the oscillating motion by last draft link realizes moving up and down of needle-bar, so can significantly improve motion of mechanism speed and mechanical efficiency, reduces noise.The fulcrum of controlling the fork of needle-bar motion simultaneously designs in the swing arm that knocking-over bar is installed, and makes when regulating double rib warp loom two knocking-over bar spacings, and the relative position between needle-bar and the knocking-over bar is constant substantially.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of first embodiment of the present utility model.
Fig. 2 is the left-half structural representation of second embodiment of the present utility model.
Among the figure: 3. eccentric drive mechanism, 7. in the middle of swing arm, 8. adjust connecting rod, 9. drive link, 10. draft link, 11. cruciform joints, 12. upper pendulum bar, 13. needle-bar connecting rods, 14. needle-bars, 15. knitting needle, 16. knocking-over bars, 17. swing arms, 18. frame, 19. middle balance staffs, 20. balance staffs, 21. bearing block, 22. adjust installing hole.
The specific embodiment
As shown in Figure 1 be first embodiment of the present utility model, have needle-bar 14, knitting needle 15, needle-bar connecting rod 13, swing arm 17, drive link 9, middle swing arm 7, middle balance staff 19, balance staff 20, eccentric drive mechanism 3.Swing arm 17 is installed some groups on the length direction of warp knitting machine, needle-bar 14 and knitting needle 15 are installed on the needle-bar connecting rod 13, swing arm 17 and middle swing arm 7 are installed on balance staff 20 and the middle balance staff 19, balance staff 20 and middle balance staff 19 are installed on the frame 18, the end of swing arm 17 is connected with adjustment connecting rod 8 by cruciform joint, adjusting connecting rod 8 is connected with frame 18 by cruciform joint 11, middle swing arm 7 and eccentric drive mechanism 3, the cruciform joint 11 that is connected with drive link 9 flexibly connects, the other end of drive link 9 is connected with needle-bar connecting rod 13 by cruciform joint 11, upper pendulum bar 12, draft link 10 splits up and down, their two ends respectively with needle-bar connecting rod 13, swing arm 17 flexibly connects, needle-bar connecting rod 13 constitutes four-bar linkage structure by upper pendulum bar 12 and draft link 10 with swing arm 17, swing arm 17 is as the frame of this quadric chain, upper pendulum bar 12, draft link 10 is as the side link of this four-bar linkage structure, upper pendulum bar 12 and the cruciform joint 11 coaxial connections that are connected drive link 9.Swing arm at ordinary times 17 is motionless, when needs are adjusted double rib warp loom two knocking-over bars 16 spacings, as long as it is middle spot wobble with balance staff 20 that the length of adjusting connecting rods 8 and drive link 9 by cruciform joint 11 adjustment can make swing arm 17, because knocking-over bar 16 is installed in the swing arm 17, spacing that knocking-over bar is 16 and needle-bar height are adjusted to the machine scope of application.During the warp knitting machine operation, swing arm 7 was the center swing with middle balance staff 19 in the middle of eccentric drive mechanism 3 on the main shaft drove, middle swing arm 7 drives needle-bar connecting rods 13 by drive link 9 and moves up and down, realize knitting needle by the braiding requirement with knocking-over bar 16 certain distance scopes in the rectilinear motion that is similar to finish looping mechanism.
As shown in Figure 2 be the left-half of second embodiment of the present utility model, the complete machine left-right symmetry, other parts as mentioned above, just balance staff 20 is installed on the bearing block 21, bearing block 21 is installed on the frame 18 by adjusting hole 22, compare with the fixed bearing mode that balance staff 20 is installed on the frame 18,, can obtain wideer knocking-over bar 16 spacings by adjusting the distance between the bearing block 21.
