Description
Technical field
The present invention relates to the servicing unit of warp knitting machine, the thread tension device particularly in these warp knitting machines.
Background technology
Warp knitting machine is when running well, and warp thread gets off from unwinding warp beam, and send into cam system according to certain warp run-in, weave for loop-forming element, such process is called the warp let-off.The system completing this process is called feeding system of warp.Feeding system of warp directly affects through compiling the quality of product and flower pattern kind, and different warp knitting fabrics has different requirements to let-off motion and warp run-in, and warp run-in must accurately control, and makes it consistent with grey cloth structure, could form the fabric meeting technological requirement.If warp run-in controls bad, may cause Yarn break, affect production efficiency, the density of grey cloth can not ensure, affects grey quality.As can be seen here warp-feeding mechanism importance, simultaneously the tension force of warp knitting machine controls to be the important step of warp-feeding mechanism.
At present, many warp knitting machines all adopt spring chain sprocket wheel of ining succession to carry out tension compensating, thus control tension force.These part movement are more, and need butter lubrication on piece surface, in machine running process, greasy dirt can pollute fabric, and makes troubles to cleaning work.And these parts are easy to wear, the life-span is shorter, often needs to change, and reduces production efficiency.
Wang Zhanhong has invented " a kind of tension compensating mechanism of Raschel looms ", application publication number is CN201220053995.4, date of publication is on 02 20th, 2012, this contrive equipment comprises transmission mechanism, eccentric shaft, tension rail, flexible couplings etc., this device can compensate yarn tension in time when yarn lopping weaves, and yarn tension is easy to adjust, the long service life of bearing, production efficiency is high, is useful in many comb Raschel loomss.
The tensioner of existing warp knitting machine, many devices are handed over complicated, can not ensure the even of yarn tension, have impact on the accuracy and the uniformity of sending yarn, thus impact fabric quality and production efficiency.
Summary of the invention
For above-mentioned Problems existing, the present invention can design a kind of device for adjusting tension of yarn, solves the tension recovery phenomenon occurred in braiding process, improves warp tension stability, and adjustable yarn scope is relatively wider, does not have special requirement to the kind of yarn.
For solving above-mentioned technical problem, the present invention adopts so a kind of two-needle bar through compiling small sample loom device, this device comprises: comprise lever jack, connecting rod, sleeve, clamping plate, spring, yarn etc., the wallboard of warp knitting machine is installed the first lever jack of at least one; Described connecting rod two ends are fixed on the wallboard of warp knitting machine; Described both sides clamping plate make to be screwed on connecting rod, and clamping plate are provided with groove, and sleeve can move along groove; Described sleeve two ends are placed in the groove of clamping plate, and are connected with connecting rod by spring; Described spring one end is hooked on connecting rod, the other end is hooked on sleeve; Described yarn is walked around sleeve through lever jack and is entered knitting zone.
Described lever jack is at least one, can increase according to yarn radical, when lever jack quantity increases, should arrange by staggered parallel up and down, and spaced certain distance, thus play the effect of dividing sinker, many lever jacks are arranged on the wallboard of warp knitting machine.
Described sleeve is placed in the groove of clamping plate, and the two ends of sleeve are connected with spring simultaneously, and by the stretching of spring, sleeve can move along groove direction in the groove of clamping plate.In described sleeve inner, roller bearing arrangement is installed, makes sleeve along sending the rotation of yarn direction, thus reduce the friction of yarn, and play the effect sending yarn.
Described Boards wall is on connecting rod, and clamping plate and connecting rod at right angle setting, but the center line of clamping plate can not vertically, certain angle is arranged in clamping plate tiltable, and the angle of inclination can regulate according to actual conditions such as the tension force of yarn installs.
After adopting said apparatus, warp thread is in extended state when walking around sleeve by effect of stress, a large amount of warp thread is when being in equal state, in yarn, stress can gather together, according to stress polymerization principle, all stress embodies a concentrated expression of the pulling force to sleeve, be delivered to spring by lever jack thus make spring tension elongated, when the pulling force in yarn reduces, spring starts to recover original state, force yarn tensioning, tension force is applied to yarn, in solution practical operation, warp thread is when swinging with sley bar, occurring relaxing causes yarn can not be fed to the problem of knitting needle, improve the quality of fabric.
In braiding process, when yarn tension increases, by sleeve extension spring, now spring also can limit elongation, thus suitably regulates the tension force of yarn; When strain is relieved, spring contraction, now spring also has certain elongation, thus increases yarn tension, and this structure is simple, long service life, convenient operation, and adjustable range is wide, and yarn applicability is good.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
Fig. 1 is the schematic perspective view of the tensioner of a kind of warp knitting machine of the present invention.
Fig. 2 is the front view of the tensioner of a kind of warp knitting machine of the present invention.
Fig. 3 is the side view of the tensioner of a kind of warp knitting machine of the present invention.
Detailed description of the invention
See the tensioner of a kind of warp knitting machine shown in Fig. 1 to 3, comprise lever jack 1, connecting rod 2, sleeve 3, clamping plate 4, spring 5, yarn 6 etc., it is characterized in that: the first lever jack 1 installing at least one on the wallboard of warp knitting machine; Described connecting rod 2 two ends are fixed on the wallboard of warp knitting machine; Described both sides clamping plate 4 make to be screwed on connecting rod 2, and clamping plate 4 are provided with groove, and sleeve 3 can move along groove; Described sleeve 3 two ends are placed in the groove of clamping plate 4, and are connected with connecting rod 2 by spring 5; Described spring 5 one end is hooked on connecting rod 2, the other end is hooked on sleeve 3; Described yarn 6 is walked around sleeve 3 through lever jack 1 and is entered knitting zone.
