Detailed Description

To facilitate understanding of those skilled in the art, the present invention will be described in further detail with reference to specific embodiments and drawings.

Referring to fig. 1-2, an embodiment of the present invention includes:

a low-abrasion loom comprises a frame, an opening mechanism, a weft insertion mechanism, a beating-up mechanism, a winding mechanism and a let-off mechanism, wherein the weft insertion mechanism comprises a weft straightener 02 and a low-abrasion monofilament tensioner, and the low-abrasion monofilament tensioner straightens weft yarns 01 output by the weft straightener 02 and then sends the weft yarns to a shed. This low-wear monofilament tensioner includes support frame 1, the screw rod 2, preforming 3 on the three, preforming 4 under the three, the nut 5, dial line ware 6, screw rod 2 sets up on support frame 1, preforming 3 and three preforming 4 suit down are on screw rod 2 on the three, preforming 4 and screw rod 2 sliding connection under preforming 3 and the three on the three, the adjustable dynamics that compresses tightly between preforming 3 and the preforming 4 down of nut 5, dial line ware 6 and set up on support frame 1, weft centre gripping is in last preforming 3 and 4 clearances of preforming down and is straightened by dialling line ware 6 and tighten in proper order. The wire poking device 6 comprises a wire poking seat 7 fixedly connected with the support frame 1, a first support plate 8 and a second support plate 9 which are arranged on the wire poking seat 7, a wire poking rod 10 which can rotate relative to the wire poking seat 7, and whether the wire poking rod 10 can rotate relative to the wire poking seat 7 or not is controlled by a limiter. The stopper includes the gear of cover on dialling line pole 10, sets up the catch wheel pole on dialling line seat 7, and the catch wheel pole realizes can not dialling line pole 10 for dialling line seat 7 pivoted state through the tooth of a cogwheel with the tip card on the gear. The wire pulling seat 7 is provided with a cavity for the gear to rotate. Set up first through-hole 11 on the first backup pad 8, set up second through-hole 12 on the second backup pad 9, dial line pole 10 and be located between first backup pad 8 and second backup pad 9. The lower pressing sheet 4 has a hemispherical curved surface 15 and a circular truncated cone 13 disposed at the center of the concave side of the curved surface 15, the upper pressing sheet 3 has the same shape and size as the lower pressing sheet 4, the lower pressing sheet 3 has a hemispherical curved surface 16 and a circular truncated cone 17 disposed at the center of the concave side of the curved surface 16, and the convex side of the curved surface of the upper pressing sheet 3 and the convex side of the curved surface of the lower pressing sheet 4 are opposed to each other and pressed against each other. The lower pressing plate 4 is indirectly connected with the nut 5 through a spring 14, one side of the spring 14 is abutted with the curved surface concave part of the lower pressing plate 4, and the other side of the spring is abutted with the nut 5.

In the weaving industry, the weft yarns are produced by upstream enterprises and then wound into a yarn roll, so that the weft yarns in the yarn roll need to be corrected and then stretched to be delivered to a shed of a loom. The specific working principle is as follows, a yarn roll with a proper specification is taken, a thread end is found on the yarn roll and is pulled to the input end of the weft straightener, weft yarns are output from the output end of the weft straightener after being corrected by the weft straightener, the output thread end sequentially passes through three gaps formed by three groups of upper pressing sheets and lower pressing sheets, then passes through a first through hole and a second through hole and finally reaches a shed, the weft yarns positioned between the first through hole and the second through hole can also be acted by a thread pulling rod, and the thread pulling rod pulls the weft yarns to enable the weft yarns to deviate to a certain degree, so that the weft yarns are straightened and tightened, and the tightened weft yarns enter the shed according to a preset speed. Because the curved surface that upper and lower holding-down blades held the woof can take place to warp through nut, spring, the clamping force of adjustable upper and lower holding-down blades to the woof guarantees that upper and lower holding-down blades are with appropriate clamping force centre gripping woof to effectively avoid the cracked condition of woof to take place.
