Description
Technical Field
The utility model relates to a weaving equipment field, especially a harness wire convenient to threading.
Background
The harness wire is one of the accessories of the weaving machine and is made of wires, steel wires or steel sheets. The middle part is provided with a small hole (heddle eye) for the warp yarn to pass through. Each heddle controls one warp yarn. During weaving, the warp yarns are driven to do lifting motion to form a shed so as to be convenient for introducing weft yarns. The heddle eyes of the existing heddle are of a closed structure, and when the heddle is used for drafting, because the heddle eyes are small, the warp yarns are difficult to pass through the heddle eyes, and the problems of eye fatigue of workers, heddle eye mistake-threading and the like are easily caused by long-time drafting.
SUMMERY OF THE UTILITY MODEL
In view of the above insufficiency, the utility model aims to provide a harness wire convenient to threading, the heddle eye of this harness wire is open structure, during the drafting the workman only need with the warp directly by the heddle eye opening part slide in can, convenient and fast. And after the heald wires after the drafting are tensioned by the heald frame, the heald eyes can be automatically closed, so that the situation that warp yarns run out of the heald eyes in the weaving process is avoided.
In order to achieve the above purpose, the technical scheme of the utility model is that:
a heddle convenient to thread comprises two pull rods which are oppositely arranged and arranged in a straight line shape, wherein each pull rod is provided with a first end and a second end, the first end of each pull rod is fixedly connected with a pull ring, a first heddle eye plate which is fixedly connected with the second end is arranged between the two pull rods, and the first heddle eye plate is arc-shaped and has elastic restoring capacity; the second end of one pull rod is fixedly connected with a second heddle eyelet plate opposite to the first heddle eyelet plate, the length of the second heddle eyelet plate is longer than the chord length of the first heddle eyelet plate, a gap exists between one end, which is not connected with the second end, of the second heddle eyelet plate and the pull rod, the second heddle eyelet plate is further provided with a clamping hole, the inner side surface of the first heddle eyelet plate is provided with a clamping plate, and the clamping plate enters the clamping hole after the first heddle eyelet plate is stretched to form a closed heddle eye.
Further, one end of the second heddle eye plate, which is not connected with the second end, is provided with a lead-in slope.
Furthermore, a plurality of convex teeth are arranged on the upper part of the clamping plate.
The working principle is as follows: when a draw is required, the heddles installed in the heddle frame are in an untensioned state. At this time, the clamping plate on the first heddle eyelet plate is not inserted into the clamping hole of the second heddle eyelet plate. The worker only needs to enter the warp yarns from the gap between the second heddle eye plate and the pull rod. When the whole drafting is finished, the worker adjusts the heald frame to tension the heald, the bent first heddle eyelet plate is gradually straightened in the tensioning process, and the clamping plate gradually moves towards the clamping hole and finally extends into the clamping hole in the straightening process. When the cardboard stretches into in the card hole completely the back cardboard receives the restraint of card hole and can't remove along the direction of pull rod, the cardboard card dies in the card hole promptly, and the heddle eye is closed this moment, and the warp can not be in placing the in-process from the heddle eye roll-off.
Has the advantages that: through the structure, a worker only needs to press the warp yarns against the pull rod and then pulls the warp yarns towards the heddle eye direction, and the heddle eye penetration of the warp yarns can be realized simply and quickly.

Reference numerals: 100. the pull rod 110, the first end 120, the second end 200, the pull ring 300, the first heddle eye plate 310, the clamping plate 320, the convex teeth 400, the second heddle eye plate 410, the clamping holes 420 and the lead-in slope.
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.
A heddle for facilitating threading, as shown in fig. 1, comprises two opposite draw bars 100 arranged in a line. Specifically, the tie rod has a first end 110 and a second end 120. Wherein, a pull ring 200 which can be sleeved into the heald frame is fixedly connected with the first end of each pull rod. In addition, a first heddle eyelet plate 300 is arranged between the two pull rods, and the first heddle eyelet plate is arc-shaped and has elastic recovery capability. Two ends of the first heddle eye plate are respectively fixedly connected with the second end of the pull rod. Meanwhile, a second end of one of the two pull rods is fixedly connected with a second heddle eyelet plate 400, the length of the second heddle eyelet plate is longer than the chord length of the first heddle eyelet plate, and a gap through which a yarn can pass is formed between one end of the second heddle eyelet plate, which is not connected with the second end, and the pull rod. It should be noted that the second heddle eyelet plate is further provided with a clamping hole 410, and the inner side surface of the first heddle eyelet plate is provided with a clamping plate 310. The clamping plate is close to the clamping hole along with the reduction of the curvature of the first heddle eyelet plate and is finally clamped in the clamping hole, so that the first heddle eyelet plate and the second heddle eyelet plate can form a closed heddle eye.
As a further modification of the above embodiment, in order to facilitate the entry of warp yarns into the heddle eyelet, the end of the second heddle plate not connected to the second end is provided with a lead-in ramp 420 turned outwards.
As a further improvement of the above embodiment, a plurality of convex teeth 320 are provided on the upper portion of the card plate for more stable engagement with the card hole when the card plate is in the card hole.
