Description

Opening harness wire

Technical Field

The utility model relates to a weaving equipment field, especially an opening harness wire.

Background

In the weaving process, the lifting of the heddles drives the warp yarns to move up and down to form a shed, and the weft yarns are interwoven with the warp yarns to form a fabric after being introduced into the shed. Heddles are an important accessory in weaving machines for lifting warp yarns up and down. The heddle consists of a body, an upper heddle lug and a lower heddle lug at two ends of the body, wherein the body is provided with a through heddle eye for threading warp yarns. In the actual process, each time of fabric style change, a worker needs to perform new drafting, and the drafting labor intensity of the worker is high and the drafting efficiency is low because the diameter of the heddle eye is small in the drafting process.

SUMMERY OF THE UTILITY MODEL

In view of the above, the utility model aims at providing an open harness wire, the opening when can realizing the warp and threading is worn the yarn, the degree of difficulty when reducing workman's working strength and threading.

In order to achieve the above purpose, the technical scheme of the utility model is that:

an open heddle comprising a body; the body comprises a first half ring and a second half ring which are combined to form an O-shaped heddle eye; the upper end of the first half ring and the upper end of the second half ring are fixedly connected and are also fixedly connected with an upper screw rod which is longitudinally arranged, and the upper end of the upper screw rod is fixedly connected with an upper heddle lug; the lower end of the first half ring is fixedly connected with a lower screw rod which is longitudinally arranged, the lower end of the lower screw rod is fixedly connected with a lower heddle, and the section of the upper end of the lower screw rod is semicircular; the lower end of the second half ring is fixedly connected with an auxiliary rod, the auxiliary rod protrudes along the radial direction of the second half ring, and the cross section of the auxiliary rod is semicircular; after the first half ring and the second half ring are closed, the upper end of the lower screw rod and the auxiliary rod are overlapped to form a cylindrical lock cylinder, and a lock groove is annularly formed on the surface of the lock cylinder; the lower screw rod is sleeved with a magnetic buckle matched with the locking groove; the magnetic buckle comprises a sleeve which is sleeved on the lower screw rod in a sliding mode, a cavity is formed in the sleeve, the lower portion of the cavity is cylindrical, the upper portion of the cavity is gradually closed, an iron ring and a reset spring are arranged in the cavity, the iron ring and the reset spring are sleeved on the lower screw rod, the reset spring is abutted to the lower surface of the iron ring, a plurality of iron beads are arranged in the cavity and are circumferentially and uniformly distributed on the outer side surface of the lower screw rod, and the iron beads are arranged above the iron ring.

Further, the lower screw rod is made of 304 stainless steel.

Further, the sleeve is made of nylon.

The working principle is as follows: when the magnetic button works, the magnetic button is sleeved on a lock cylinder formed by the upper end of the lower screw rod and the auxiliary rod, and at the moment, an iron ball in the magnetic button is positioned in a lock groove on the surface of the lock cylinder, so that the iron ball forms a longitudinal limit on the lock cylinder. The first half ring and the second half ring are guaranteed not to be opened when warp yarns are lifted. When the heald needs to be healed again, a worker places a magnet with strong magnetism below the magnetic buckle, the iron ring is attracted by the magnet to overcome the action force of the reset spring to move downwards, when the iron bead is not pressed by the iron ring, the iron bead also moves downwards under the action force of the magnet to fall out of the lock groove, the limiting effect of the iron bead on the lock column is relieved, the magnetic buckle can slide on the lock column, the worker can longitudinally pull out the lock column along with the magnetic buckle, after the auxiliary rod loses constraint, the second half ring can be separated from being matched with the first half ring, and when the worker heals, warps can enter from the openings of the first half ring and the second half ring.

Has the advantages that: through the structure, when a worker heals, the warp yarns are pulled in from the opening parts of the first half ring and the second half ring, the original step of penetrating the fine heald eyes is omitted, the difficulty of the heald is greatly reduced, and the working strength of the worker is further reduced.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The shedding heddle as shown in fig. 1 to 4 comprises a body 100, an upper screw 200, an upper heddle 300, a lower screw 400 and a lower heddle 500. The body is composed of a first half ring 110 and a second half ring 120, which are C-shaped. Specifically, the upper end 111 of the first half ring and the upper end 121 of the second half ring are fixedly connected into a whole and are fixedly connected with the upper screw rod which is longitudinally arranged. And the upper end 210 of the upper cord rod is fixedly connected with the upper heddle ear. In addition, the lower end 112 of the first half ring is fixedly connected with a lower screw rod 400 which is longitudinally arranged, and the section of the upper end 410 of the lower screw rod is semicircular. In addition, the lower end 420 of the lower lead screw is fixedly connected with the lower heddle. Meanwhile, as shown in fig. 2, a sub-rod 600 is fixedly connected to the lower end 122 of the second half ring. In detail, the secondary rod extends outwards along the radial direction of the second half ring, and the section of the secondary rod is also semicircular. When the first half ring and the second half ring are closed, the first half ring and the second half ring form an O-shaped heddle eyelet 130. The upper end 410 of the lower lead screw and the sub-rod 600 together form a cylindrical lock cylinder 700. The surface of the lock cylinder is provided with a ring of lock grooves 710. But to limit the split cylinders. The lower screw rod is sleeved with a magnetic buckle 800 matched with the lock groove. Specifically, the magnetic buckle comprises a sleeve 810 sleeved on the lower screw rod, and a cavity 811 is arranged in the sleeve.
