TECHNICAL FIELD

[0001] The utility model belongs to the technical field of textile equipment, especially relate to a flexible double sword bar device for loom. BACKGROUND

[0002] The flexible sword bar loom is mainly used for fabric weaving in the textile industry, and its core feature lies in the use of flexible sword bars to complete the weft insertion action. Compared with the rigid sword bar loom, it has stronger adaptability, higher efficiency and wider application range. Its core components include sword bars made of flexible materials (such as stainless steel belts and carbon fiber belts), which can bend and adapt to complex motion trajectories. The sword head installed at the end of the sword bar is responsible for clamping the weft yarn and ensuring accurate transfer. The sword transmission mechanism drives the sword bar to reciprocate through gear and rack, connecting rod or cam, and the guiding device ensures the stability of the sword bar during movement, reducing vibration and deviation.

[0003] According to the relevant information, the patent application number 2021100925619 is a flexible large sword bar velvet loom, which belongs to the technical field of textile machinery. The uniform acceleration shedding opening device is designed and manufactured according to the special curve principle of eccentric cam. In the shuttle throwing and beating-up device, the flexible sword belt reciprocates to complete the shuttle throwing and weft insertion with the sword head. The cross section of the flexible sword belt in the entering shed part is slightly convex arc shape. The reciprocating motion of the flexible sword belt is completed by the chain hole in the sword belt driven by the chain wheel of the sword transmission gear box of the sword loom. The base at the two ends of the linear guide rail of the velvet cutting device has an adjustable front and rear swing and left and right lifting device. The invention not only solves the key problem of double-layer double-shed double-sword bar velvet loom that cannot weave thin velvet, but also breaks through the single problem of double-layer double-shed double-sword bar cutting velvet surface. It also solves the problems of low yield, poor quality and multiple weft winding processes of single-layer single-shed weft velvet loom.

[0004] The patent application number 2018220707377 is a sword wheel for sword bar weft insertion of sword bar loom, which includes wheel teeth on the rim matched with the pitch of sword belt holes. The center hole of the sword wheel is provided with a plurality of light holes distributed in a circular array along the radial direction outward to the rim. The nearest first right triangle hole to the center hole is arranged in a positive direction. An inverted second inverted triangle hole is inserted between two first right triangle holes. A third right triangle hole is arranged in a positive direction and parallel to the bottom edge of the second inverted triangle hole. Two fourth inverted triangle holes are inserted between two adjacent third right triangle holes. A fifth trapezoidal hole is arranged in a positive direction and parallel to the bottom edge of the fourth inverted triangle hole. Two sixth inverted triangle holes are arranged between two fifth trapezoidal holes. The sword wheel of the utility model has large diameter and light weight, meeting the requirements of high speed transmission ratio.

[0005] But there are still the following problems: in the use process of double sword lever loom, the tightness of double sword lever cannot be accurately adjusted, and the efficiency is not high in the process of weft insertion. SUMMARY

[0006] The utility model discloses a flexible double sword lever device for loom to overcome the deficiency in the prior art.

[0007] In order to realize the above-mentioned purpose, the utility model adopts the technical scheme of:

[0008] A flexible double sword lever device for loom, including frame, sword wheel, sword lever I, sword lever II, limit shaft, guide shaft, nervous axis, control assembly, the sword wheel is connected on the frame, be equipped with two sword lever on the sword wheel respectively sword lever I and sword lever II, the other side of frame is connected with control assembly, limit shaft, guide shaft, nervous axis all are connected to the frame through control assembly.

[0009] In the working process, the sword head of sword lever weft insertion mechanism clamps and takes weft yarn to pass through the shed, at this moment, the sword wheel reciprocating rotation drives flexible sword lever I and sword lever II to enter and exit the shed, the limit shaft is used for controlling sword lever I and sword lever II to accurately clamp the sword wheel, the guide shaft is used for separating sword lever I and sword lever II, and the control assembly is used for controlling the nervous axis to adjust the tightness of sword lever I and sword lever II.

[0010] Preferably, the control assembly includes a screw rod, a handle, and a nut, the nut is fixed on one side of the screw rod, the screw rod passes through the nut and is connected with the nut through threads, the handle is fixed on the top of the screw rod, when the tightness needs to be adjusted, the handle is rotated to drive the screw rod to rotate, and then the nut drives the nervous axis to move up and down along the screw rod, so as to change the tightness of sword lever I and sword lever II.

[0011] Preferably, the nervous axes are staggered in up and down directions.

[0012] The utility model has the advantages that compared with the prior art, the utility model has the advantages that:

[0013] By rotating the screw rod, the nut moves up and down along the screw rod under the action of threads, at the same time, the nut drives the nervous axis to move up and down synchronously, and then the running route of sword lever I and sword lever II is changed, so as to accurately adjust the tightness of sword lever I and sword lever II.
