Description

Technical Field

[0001] This utility model relates to the field of gauze loom technology, and in particular to a multi-functional heddle for a loom. Background Technology

[0002] Gauze weave refers to a fabric structure in which the warp yarns of two systems (ground and skein) and one system (weft) are twisted together. The openings formed by the twisting of the warp yarns in gaveneer fabric are called skein openings. A gaveneer structure with evenly distributed skein openings and no visible stripes is called a yarn weave, such as the weave of mosquito netting and sieve silk. Gauze with skein openings arranged along the warp direction is called straight gaveneer, such as curtain gaveneer; gaveneer with skein openings arranged along the weft direction is called horizontal gaveneer, such as Hangzhou gaveneer. The simplest yarn weave structure has one skein warp and one ground warp alternating, with each shuttle starting a skein. Five shuttles per skein is a relatively simple horizontal gaveneer structure.

[0003] A search of Chinese patent publication number CN217438385U reveals a durable heddle for looms.

[0004] The above technical solution includes a heddle body and a reinforcing device. Two lifting heddles are fixedly connected to the surface of the heddle body, and two heddle holes are formed on the surface of the heddle body. The reinforcing device includes two long steel rods, both of which are slidably connected to the interior of the heddle body. Positioning holes are formed on the surface of each of the two long steel rods, and short steel rods are slidably connected to the inner walls of the two positioning holes. External threads are formed on both sides of each short steel rod, and nuts are threaded onto the surface of the external threads. A sliding rod is slidably connected to the interior of each long steel rod. A rotating block is fixedly connected to the end of the sliding rod away from the long steel rod, and a rope is fixedly connected to the end of the long steel rod away from the sliding rod. This utility model solves the problem of easy bending during use caused by materials made of plastic-steel.

[0005] However, in the above-mentioned scheme, during the spinning process, the yarn spinning action causes large changes in the force on the yarn passing through the heddle, and the yarn tension is not stable enough, which can easily cause the yarn to fly off or get stuck.

[0006] Therefore, we propose a multi-functional heddle for looms. Utility Model Content

[0007] The present invention aims to solve the technical problems existing in the prior art and provide a multi-functional heddle for looms.

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments: Embodiment 1

[0023] Please see Figures 1 to 2 Embodiment 1 describes a heddle 10 with multiple heddle eyes 11 for threading. Each heddle eye 11 has a thread-pressing assembly 20, which includes a thread-pressing rod 22 sliding within the heddle eye 11. The thread-pressing rod 22 clamps the yarn in conjunction with the heddle eye 11. A connecting rod 24 is fixedly connected to the lower end of the thread-pressing rod 22, connecting the thread-pressing rod 22 and a spring sleeve 25. The spring sleeve 25 is fixedly connected to the lower end of the connecting rod 24, fixing one end of a first spring 27. A spring sleeve 27 is fixedly connected to the lower end of the spring sleeve 25. Spring 27, the first spring 27 is used to relieve the pressure of the yarn passing through the heald eye 11. The lower end of the first spring 27 is fixedly connected to the spring seat 26. The pressure rod 22 is slidably connected in the limiting groove 21 and the sliding groove 23. The connecting rod 24 is in the sliding groove 23 at one end. The function of the limiting groove 21 is to cooperate with the sliding groove 23 to limit the pressure rod 22. The limiting groove 21 is set on one side of the short side of the heald eye 11, and the sliding groove 23 is set on the other side of the heald eye 11. The length of the limiting groove 21 depends on the length of the heald eye 11. Spring sleeve 25 is slidably connected in the sliding groove 23. Spring seat 26 is fixedly connected to the bottom end face of the sliding groove 23.

[0024] In this embodiment, the yarn passes through the heddle eye 11, releasing the first spring 27. The first spring 27 pushes the spring sleeve to move, and the spring sleeve 25 drives the connecting rod 24 to slide upward. The movement of the connecting rod 24 causes the pressing rod 22 to move upward. The pressing rod 22 squeezes the yarn at one end of the heddle eye 11, thereby restricting the yarn. When the yarn is too loose, the squeezing of the pressing rod 22 prevents the looser part of the yarn from passing through the heddle eye 11, thus avoiding yarn slippage. When the yarn is too tight, the yarn can squeeze the pressing rod 22, thereby squeezing the first spring 27 and relieving the pressure on the yarn.

[0025] Example 2

[0026] Please see Figure 1 and Figure 3 Example 2 describes a slide groove 23 connected to a reset assembly 30. The reset assembly 30 includes a slot 32, one end of which is connected to the slide groove 23 and the other end extends to the surface of the heddle 10. A connecting plate 33 is slidably connected within the slot 32. The connecting plate 33 is used to transmit power. One end of the connecting plate 33 extends out of the slot 32 and is fixedly connected to a sliding button 31. Pressing the sliding button 31 causes the first spring 27 to compress, and vice versa, it resets. The other end of the connecting plate 33 extends into the slide groove 23 and is fixedly connected to a pressure block 34. The pressure block 34 is located at the moving end of the spring sleeve 25. The pressure block 34 contacts the spring sleeve 25 and applies pressure to reset the spring sleeve 25. The position of the pressure block 34 is equivalent to the position of the spring sleeve 25 when the pressure rod 22 moves to the end. A second spring 35 is fixedly connected to the lower end of the connecting plate 33. The compression of the second spring 35 is not greater than the length of the heddle eye 11. The function of the second spring 35 is to reset the pressure block 34.

[0027] In this embodiment, pressing the sliding button 31 causes the connecting plate 33 to slide within the slot 32, and the pressure block 34 at the other end of the connecting plate 33 slides downward within the slot 23, thereby squeezing the spring sleeve 25. The squeezing of the spring sleeve 25 causes the first spring 27 to compress, thereby resetting the wire pressing rod 22 at the end of the movable heddle eye 11, which can clear the heddle eye 11 and facilitate threading.
