Further, the double-end rapier 23 comprises a straight rod 231 and a triangular head 232 with two circular arc ends, one side of the circular arc triangular head 232 is provided with a notch 233 for clamping the weft thread end, and a spring clamp 433 is arranged inside the notch 233.

In this embodiment, circular-arc triangle head 232 sets up and is used for carrying out the joint pulling to the end of a thread of weft for weft enters into warp, and is stayed in warp, and the setting of spring clamp 433 is used for carrying out the centre gripping to the end of a thread of weft, thereby realizes that the end of a thread of weft is driven by double-end rapier 23.

Furthermore, the straight bar 231 slides in the groove 211 formed on the inner side surface of the guide groove 21 through the convex strips 234 on both sides, the ends of the two guide grooves 21 close to each other are rotatably provided with gear-shaped rapier guiding wheels 22, the rapier guiding wheels 22 are engaged with the tooth grooves 235 on the bottom surface of the straight bar 231, and the rapier guiding wheels 22 are in transmission connection with the power part 3.

In this embodiment, the gear-shaped rapier guiding wheel 22 drives the tooth grooves 235 on the bottom surface of the straight rod 231 to move, so that the double-headed rapier 23 reciprocates between the left and right guide grooves 21, and the two ends of the straight rod 231 are both triangular, so as to be conveniently and smoothly inserted into the left and right guide grooves 21.

Further, the guide groove 21 is fixedly connected to a bracket 24 on the side where the triangular head 232 is provided with the notch 233, and the bracket 24 is rotatably provided with a thread end processing part 4 for facilitating the clamping of the notch 233 for cutting and moving the weft.

In the present embodiment, the thread end processing part 4 is used to cut the weft thread by hooking the weft thread in the notch 233 of the triangular end 232 of the double-headed rapier 23.

Further, the thread end processing part 4 comprises a rotating plate 41 fixed below the bracket 24 through a bearing, a motor 42 is fixedly connected to the upper end of the rotating plate 41, and two thread end balls 43 fixed through bearings are respectively arranged at two ends of the rotating plate 41.

In the present embodiment, the thread end processing unit 4 is configured to cut the weft thread of the previous time and engage the double-headed rapier 23 with the weft thread of the next time, so that the positions of the two thread end balls 43 are alternately changed, and the thread end of the weft thread held by the outer thread end balls 43 is engaged and pulled by the notch 233 of the triangular head 232.

Further, the thread end ball 43 is provided with a through notch 431, the through notch 431 is provided with a front section and a rear section along the moving direction of the weft thread, the front section is provided with a cutting piece 432 for cutting the weft thread, and the rear section is annularly provided with a plurality of spring clamps 433 for locking the weft thread in a clasping manner to prevent retraction.

In the present embodiment, the through notches 431 are provided so that the two thread end balls 43 can clip the weft thread into the through notches 431 and be clamped and fixed by the internal spring clips 433 during the process of rotating the exchange position, thereby realizing the clamping and fixing of the triangular head 232 when the double-end rapier 23 moves. The cut-off elements 432 in the knob 43 cut the weft thread alternately and successively under the control of the sensors 212 and plc, and only the cut-off elements 432 in the knob 43 located on the inner side perform the cutting operation at a time. The spring clamp 433 automatically snaps-in and secures the weft thread that enters the through-going notch 431.

Further, the cutoff part 432 comprises a guillotine 4322 controlled by a hydraulic cylinder 4321, the guillotine 4322 moves up and down along a limiting groove penetrating the upper side of the notch 431, the upper end of the guillotine 4322 is rotatably connected with the hydraulic cylinder 4321 through a lever 4323, and the hydraulic cylinder 4321 is electrically connected with the two sensors 212 on the two guide grooves 21 in a one-to-one correspondence manner.

In the present embodiment, the sensor 212 on the left guide groove 21 controls the cut pieces 432 in the two thread balls 43 on the right thread end processing part 4, and the sensor 212 on the right guide groove 21 controls the cut pieces 432 in the two thread balls 43 on the left thread end processing part 4, so that the weft thread is cut and left in the warp thread for weaving.

Further, the spring clamp 433 includes a rotation rod 4331 hinged to move, a moving groove 4332 is formed in a side surface of the other end of the rotation rod 4331, a sliding foot 4333 slides in the moving groove 4332, and a spring 4334 for pushing the spring clamp 433 to move outward is disposed between the sliding foot 4333 and the accommodating groove 434 of the spring clamp 433.

In this embodiment, one end of the rotating rod 4331 on the spring clamp 433 rotates under the action of the spring 4334, and clamps the weft thread end under the cooperation of the side wall of the notch 233, so that the triangular head 232 drives the weft thread end to move; or the weft yarns are folded under the coordination of the other spring clamps 433 to clamp the weft yarns, so that the control on the yarn ends of the weft yarns is kept, the retraction of the yarn ends of the weft yarns is avoided, and the next operation cannot be smoothly carried out.

The working principle and the using process of the invention are as follows: after the double-headed rapier loom is installed, the power part 3 is started to drive the rapier wheel 22 in the weft insertion mechanism 2 to rotate, the rapier wheel 22 rotates to drive the tooth grooves 235 in the double-headed rapier 23 to move, so that the double-headed rapier 23 moves towards the right guide groove 21 along the left guide groove 21, when the triangular head 232 on the right side of the double-headed rapier 23 moves to the middle of the two head balls 43, the weft between the two head balls 43 enters the gap 233 along the arc edge and is clamped and fixed by the spring clamps 433 in the gap 233, and then the weft is separated from the head balls 43 close to the inner side of the guide groove 21, so that the weft is driven to be pulled out from the coil, and as the right end of the double-headed rapier 23 moves towards the right guide groove 21, when the right end of the double-headed rapier 23 contacts the right guide groove 21, the rotating plate 41 is driven to rotate by the rotation of the motor 42, and the two head balls 43, therefore, the thread end of the weft thread is directly drawn out from the gap 233 of the triangular head 232, the double-headed rapier 23 continues to move and is driven by the rapier guiding wheel 22 on the other side to move along the guide groove 21 on the other side, when the left end of the double-headed rapier 23 also enters the guide groove 21 on the right side on the other side, the sensor 212 on the right side senses and controls the hydraulic cylinder 4321 in the thread end ball 43 on the inner side to extend, the guillotine 4322 descends to cut off the weft thread, the cut weft thread is left in the warp thread and is vertically staggered by the warp thread, and the weaving process is completed.

When power portion 3 reverses, drive and lead sword wheel 22 and reverse, drive double-end rapier 23 reverse movement and move to left guiding groove 21, the breach 233 on left triangular head 232 carries out the joint to the weft end of a thread on the guiding groove 21 of right side and fixes to drive right side weft thread to the left side, and as above-mentioned one step, cut weft and stay in warp under the cooperation of motor 42, during self moves left guiding groove 21, so reciprocating motion, the realization is to the guide operation of weft.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
