Description
Technical Field
The utility model relates to the field of textile machinery, especially a heald frame for rapier loom.
Background
The heald frame is an important part in the loom and is a frame with heald penetrating rods and driving parts connected via upper and lower transverse beams and left and right side rails. After the heald frame is equipped with healds, the warps threaded through the healds are integrated, and the heald frame moves up and down according to the program of the shedding device along with the movement of the loom heald lifting mechanism, so that the warps are shed in layers, and weft yarns are shuttled among the warps to be interwoven into fabrics with different patterns. The existing heddles are generally formed by twisting steel wires, the number of the heddles in the heald frame generally depends on the diameter of a heddle eye in the heddle, if the heddle eye is smaller, more heddles can be arranged in one heald frame, but the workload is larger when a worker wears the healds; and if the heddle eye is smaller, the heald threading of workers is convenient, but the threading quantity of the heddles in one heald frame is smaller, so that the production efficiency of the rapier machine is influenced.
SUMMERY OF THE UTILITY MODEL
In view of the above-mentioned not enough, the utility model aims to provide a heald frame for rapier weaving machine can realize effective balance of harness wire quantity in drafting and the heald frame.
In order to achieve the above purpose, the technical scheme of the utility model is that:
a heald frame for a rapier machine comprises a body, two groups of drafting mechanisms which are arranged in the body in an up-and-down symmetrical manner, and healds which are arranged on the drafting mechanisms in a penetrating manner;
the drafting mechanism comprises a first rocker arm, a second rocker arm and a drafting rod, the first rocker arm is rotatably connected with a left side stop of the body, the second rocker arm is rotatably connected with a right side stop of the body, the drafting rod is horizontally arranged and detachably connected with inner side ends of the first rocker arm and the second rocker arm, a sleeve is fixedly connected with an outer side end of the second rocker arm, an inner side groove is hexagonal, a slot is radially formed in the side wall of the sleeve, and a plug pin capable of being inserted into the slot is arranged on the right side stop;
the heddle eyes of the heddles are round and can elastically deform when not stressed.
Further, a port of the slot is provided with a 45-degree chamfer.
Furthermore, a return spring is sleeved on the plug pin, the spring is arranged in the right side gear, and the plug pin is abutted against the side wall of the sleeve under the action of the return spring.
Furthermore, one end of the penetrating rod is connected with the second rocker arm in an inserting mode, and the other end of the penetrating rod penetrates through the first rocker arm and then is detachably connected with the first rocker arm through a pin shaft.
The working principle is as follows: the worker firstly threads the harness wire on two harness rods arranged up and down, and then fixes the harness rods on the first rocker arm and the second rocker arm. At the moment, the upper end and the lower end of the heddle are not subjected to the pulling force from the heddle drawing rod, namely, the heddle eyes on the heddle are still round, and the yarn can conveniently pass through the heddle eyes. In the process, the heddle eyes on adjacent heddles can be overlapped with each other without winding in consideration of the small gap between the yarns. And after all heddles penetrate the yarn, the upper and lower second rocker arms are rotated by an external wrench to enable the second rocker arms to rotate upwards and downwards by a certain angle respectively, the plug positioned on the body is inserted into the slot to block the second rocker arms, the heddles are deformed (the heddle eyes are changed into an oval shape from a round shape) due to the pulling force of the upper and lower heddle penetrating rods, the distance between the heddle eyes of adjacent heddles is enlarged, so that the mutual interference can not be generated, and meanwhile, the yarn can not be wound due to the undersized distance.
By the mode, the heddle eye is large when the heddle is not under tension, yarn threading is convenient, and the heddle eye becomes relatively long and narrow after being stressed, so that the occupied space in the heddle frame is reduced, and further more heddles can be inserted into a unit heddle frame, and the production efficiency is improved.

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 heald frame for the rapier loom shown in fig. 1 to 3 comprises a body 1, two sets of drafting mechanisms 2 and heddles 3, wherein the body consists of an upper crossbeam, a lower crossbeam, a left side stopper and a right side stopper. And the two groups of drafting mechanisms are symmetrically arranged in the body up and down. Meanwhile, the two groups of drafting mechanisms are rotatably connected with the body. The harness wire is detachably sleeved on the upper and lower groups of drafting mechanisms.
In particular, the drafting mechanism comprises a first rocker arm 21, a second rocker arm 22 and a drafting rod 23. The first rocker arm is rotatably connected with the left side gear of the body, and the second rocker arm is rotatably connected with the right side gear in the body. The heald penetrating rod is horizontally arranged, and two ends of the heald penetrating rod are detachably connected with the first rocker arm and the second rocker arm. Preferably, the drafting rod passes through the front end of the first rocker arm and then is inserted into the front end of the second rocker arm. In order to fix the heald-threading rod, a pin 24 is arranged on the first rocker arm, and when the heald-threading rod is mounted in place, the pin penetrates through the first rocker arm and then is inserted into the end part of the heald-threading rod.
In order to be able to rotate the first and second rocker arms through which a large number of heddles are threaded, a sleeve 25 is fixedly connected to the outer end of the second rocker arm, said sleeve being coaxial with the outer end of the second rocker arm. The groove of the sleeve is of a hexagon socket type, and a worker can drive the second rocker arm to rotate through the rocking handle with the hexagonal terminal, so that the effect of driving the drafting rod to move up and down is achieved.
Meanwhile, in order to make the heald rod rotated to the position keep fixed, a slot 26 is arranged on the sleeve, a plug 27 is arranged on the left side baffle of the body, when the heald rod rotates to the position and the sleeve rotates for a certain angle, the slot on the sleeve is opposite to the plug, at the moment, a worker inserts the plug into the slot to achieve the purpose of fixing the position of the heald rod, and the heald wire is stretched by the heald rod which moves up and down to make the heald eye 31 become long and narrow. Furthermore, the state of intensive interference is changed into the state of separation when the yarn is threaded, so that the yarn is prevented from being wound by being too close to each other or being broken due to friction with the adjacent heddles. In order to provide the effect of the repeated use of the healds in the above embodiment, the healds are twisted by manganese steel wires having a certain elastic deformability, and the eyelets 31 in the center are round when not subjected to a force. Can still rebound to the initial state without being stressed after being stretched.
As a further improvement of the above embodiment, a 45 ° chamfer is provided at the port of the slot to facilitate insertion of the plug.
As a further improvement of the above embodiment, in order to enable the latch to automatically fall after the worker rotates the drafting pole to the position, a spring 28 is sleeved on the latch, and the return spring is arranged in the right side rail. When the bolt is aligned with the slot, the bolt directly enters the slot under the action of the spring.
