Description

Technical Field

[0001] The utility model relates to the technical field of water jet braiding machines, in particular to a water jet braiding machine spray needle. Background Art

[0002] The water jet loom is a modern shuttleless loom. It uses the instantaneous negative pressure generated when water is sprayed at high speed to make the weaving silk thread spray out at high speed and straight line to replace the traditional weaving shuttle. The spray needle is one of the key components of the water jet loom. It cooperates with the water spray sleeve of the water jet loom to generate instantaneous negative pressure and make the silk thread passing through the spray needle spray out at high speed and straight line to interweave with the endless warp thread into a cloth. The spray needle in the prior art is conical, with a streamlined nozzle at the front, a rear cover with a wire inlet hole at the rear, and an O-shaped sealing ring in the middle that cooperates with the inner wall of the water spray sleeve. A conical wire hole for passing the silk thread is opened in the spray needle. When water enters the water spray sleeve and sprays out at high speed through the front end of the spray needle nozzle, an instantaneous negative pressure is generated in front of the nozzle, and the silk thread that passes through the rear wire inlet hole in the spray needle is sprayed out at high speed and straight line from the front end of the nozzle. Since the frequency and speed of the silk thread passing through the wire hole are very high, the wear of the wire inlet hole and the front end of the wire hole are very serious, which affects the service life of the spray needle.

[0003] After searching, the announcement number CN202099495U discloses a water jet loom needle, including a needle body; the front part of the needle body is a streamlined nozzle; the rear part of the needle body is provided with a back cover; the middle part of the needle body is provided with an O-ring; the needle body is provided with a conical thread hole for passing the thread; the streamlined nozzle is provided with a thread; the front of the streamlined nozzle is connected to a wear-resistant ceramic part by a thread; the back cover is provided with a threaded hole; a wear-resistant ceramic ring is provided in the threaded hole of the back cover: the outer wall of the wear-resistant ceramic ring is provided with a thread; the wear-resistant ceramic ring is provided with a hexagonal wire inlet hole. The utility model of the water jet loom needle can disassemble and assemble the wear-resistant ceramic part and the wear-resistant ceramic ring from the needle.

[0004] The spray needle of the utility model water jet loom replaces the wear-resistant ceramic parts and the wear-resistant ceramic rings by means of threads. Although the replacement is possible, the thread installation method is easily damaged. For example, the threads are prone to slippage, resulting in loose installation, or they are easily oxidized and rusted, resulting in subsequent disassembly and assembly being extremely difficult. In addition, the thread processing is difficult, and the manufacturing and processing of the threads are relatively complicated, requiring high processing precision, which cannot meet the use requirements. Therefore, a water jet weaving machine spray needle is proposed to solve the above-mentioned problems. Utility Model Content

The rear cover 104 is provided with a mounting hole 108 for mounting the wear-resistant ceramic ring 106.

[0026] In this embodiment, a sealing ring 103 is sleeved on the outer surface of the spray needle 101, and a rear cover 104 is detachably mounted on the end of the spray needle 101 away from the streamlined nozzle 102. A hexagonal wire inlet hole is provided inside the wear-resistant ceramic ring 106, and the front and rear ends of the wear-resistant ceramic part 107 are connected. The wear-resistant ceramic part 107 and the wear-resistant ceramic ring 107 are provided, so that the service life of the spray needle 101 is greatly extended, and the wear-resistant ceramic part 107 and the wear-resistant ceramic ring 106 are all detachably mounted with the spray needle 101, which further increases the service life of the spray needle body 1 of the water jet knitting machine.

[0027] In this embodiment, a disassembly and assembly structure 2 is provided on the wear-resistant ceramic ring 106 and the wear-resistant ceramic part 107, and the disassembly and assembly structure 2 includes a sleeve 201, a reset spring 203 arranged inside the sleeve 201, and a clamp fixedly installed on one end of the reset spring 203 and extending to the outside of the sleeve 201.

[0028] The clamping member is composed of a circular plate 204 and a clamping rod 205, and one end of the clamping rod 205 is welded to the circular plate 204, and the side of the circular plate 204 away from the clamping rod 205 is connected and fixed to the reset spring 203. The circular plate 204 and the clamping rod 205 form a T-shaped shape, which facilitates the full deformation of the reset spring 203 and improves the installation effect.

[0029] It should be noted that a cavity 202 is provided inside the sleeve 201, and the side of the return spring 203 away from the circular plate 204 is fixed to the inner wall of the cavity 202. The water jet knitting machine needle body 1 belongs to the conventional technology known to the public in the prior art, so its specific structure and working principle will not be described in detail in this article. When the clamping hole 206 is deep, the clamping rod 205 can be squeezed by the circular rod penetrating into the clamping hole 206.

[0030] In addition, a guide rod 209 is fixedly installed between the inner walls of the opposite side of the cavity 202, and the guide rod 209 passes through the inside of the circular plate 204. The insides of the wear-resistant ceramic ring 106 and the wear-resistant ceramic part 107 are provided with a clamping hole 206 adapted to the clamping rod 205. By installing the guide rod 209, the clamping part is linearly displaced, thereby improving the squeezing of the reset spring 203.

[0031] Embodiment 2:

[0034] By adopting the above technical solution, the installation of the disassembly structure 2 is realized, thereby the disassembly and assembly of the wear-resistant ceramic ring 106 and the wear-resistant ceramic part 107 is realized.

[0035] The working principle of the above embodiment is:

[0036] When in use, the clamping rod 205 is pressed to extend it into the interior of the sleeve 201 and squeeze the reset spring 203, and then the wear-resistant ceramic ring 106 is placed in the mounting hole 108 or the wear-resistant ceramic part 107 is placed in the streamlined nozzle 102. The reaction force of the reset spring 203 allows the clamping rod 205 to extend into the clamping hole 206, thereby achieving the installation of the wear-resistant ceramic ring 106 and the wear-resistant ceramic part 107. When disassembling, it is only necessary to squeeze the clamping rod 205 to extend it into the sleeve 201 for disassembly.
