Description

Technical Field

[0001] This utility model relates to the field of jet loom accessories, specifically a selvage winch frame. Background Technology

[0002] In the textile industry, the jet loom is an important piece of textile equipment, a shuttleless loom that uses jets of water or air to guide the weft yarn through the shed. The selvage guide, as an accessory of the jet loom, plays a crucial role in the selvage binding process. In actual production, the working environment of the jet loom needs to maintain a certain temperature and humidity, and the selvage guide needs to pass through at high speeds during operation. Over time, this leads to wear and tear on various connecting parts and guide yarn parts of the selvage guide, affecting its lifespan and requiring frequent replacement, thus increasing production costs. Therefore, it is necessary to provide a selvage binding selvage guide that is more wear-resistant and has a longer service life than common selvage guides. Utility Model Content

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] Combination Figure 1This embodiment provides a detailed description of a selvage edge winch frame, comprising: a winch frame 1, a yarn guide assembly 2, a yarn eyelet frame assembly 3, and a winch coil assembly 4; the winch frame 1 is provided with a first ceramic bushing 5, a second ceramic bushing 6, a third ceramic bushing 7, and a fourth ceramic bushing 8; the yarn guide assembly 2 includes a tension shaft 9, a first yarn guide 10, and a second yarn guide 11, the first yarn guide 10 and the second yarn guide 11 being sleeved on the tension shaft 9, and the two ends of the tension shaft 9 being connected to the first ceramic bushing 5 and the second ceramic bushing 6, respectively; the first yarn guide 10 and the second yarn guide 11 are respectively sleeved on the tension shaft 9; the first yarn guide 10 and the second yarn guide 11 are respectively connected to the first ceramic bushing 5 and the second ceramic bushing 6; the first yarn guide 10 and the second yarn guide 11 are respectively sleeved on the tension shaft 9, and the two ends of the tension shaft 9 are respectively connected to the first ceramic bushing 5 and the second ceramic bushing 6; the first yarn guide 10 and the second yarn guide 11 are respectively sleeved on the tension shaft 9, and ... The yarn guide 10 includes a first lead hole 12, a pawl 13, and a first protrusion 14; the second yarn guide 11 includes a second lead hole 15, a second protrusion 16, and a tension bracket 17; the yarn eyelet frame 3 includes an adjusting plate 18 and a third lead hole 19, and the yarn eyelet frame 3 is connected to the ear yarn frame 1 by bolts; the ear yarn coil assembly 4 includes an ear yarn coil shaft 20 and an ear yarn coil 21, the ear yarn coil 21 being sleeved on the ear yarn coil shaft 20, and the two ends of the ear yarn coil shaft 20 being connected to a third ceramic bushing 7 and a fourth ceramic bushing 8, respectively. The first ceramic bushing 5, the second ceramic bushing 6, the third ceramic bushing 7, and the fourth ceramic bushing 8 not only improve the wear resistance between the yarn guide assembly 2 and the ear yarn coil assembly 4 and the ear yarn frame 1, but also prevent rusting during long-term operation in humid environments, thus extending the service life of the ear yarn frame.

[0015] Furthermore, wear-resistant ceramic rings are installed on the inner sides of the first lead hole 12, the second lead hole 15, and the third lead hole 19. When the yarn passes through the second lead hole 15, the first lead hole 12, and the third lead hole 19, the wear-resistant ceramic rings can play a good role in wear resistance, reducing the wear caused by yarn friction on the second lead hole 15, the first lead hole 12, and the third lead hole 19 during long-term operation of the ear wire frame.

[0016] Furthermore, the pawl 13, the first protrusion 14, and the second protrusion 16 are all coated with wear-resistant ceramic. When the ear wire holder is in operation, the pawl 13 contacts the ratchet on the ear wire disc head 21, and the first protrusion 14 contacts the second protrusion 16. The wear-resistant ceramic coating on the pawl 13, the first protrusion 14, and the second protrusion 16 can reduce the wear caused by the contact of these components during operation.

[0017] Furthermore, the tension shaft 9 is made of tungsten steel, and a wear-resistant ceramic sleeve is provided between the tension shaft 9 and the first guide wire member 10 and the second guide wire member 11. Tungsten steel has excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. The first guide wire member 10 and the second guide wire member 11 are sleeved on the tension shaft 9, and the wear-resistant ceramic sleeve between them can also reduce wear caused during operation.

[0018] Furthermore, the ear wire frame 1 is provided with a bobbin hook 22, which is connected to one end of a tension spring 23, and the other end of the tension spring 23 is connected to the tension bracket 17. During operation, the tension spring 23 can be used to control the tension of the yarn.

[0019] Furthermore, it also includes a stop screw assembly 24, which is connected to the lug frame 1 by bolts.
