Abstract
Description
Technical Field
[0001] This utility model relates to the field of air-jet loom technology, and in particular to an anti-breakage yarn feeding mechanism for air-jet looms. Background Technology
[0002] Air-jet looms are shuttleless looms that use jet airflow to pull the weft yarn through the shed. The working principle is to use air as the weft-introducing medium, and the compressed airflow generated by the jet will generate frictional traction force on the weft yarn to pull it through the shed. The jet generated by the airflow achieves the purpose of weft introduction.
[0003] In the prior art, such as the Chinese patent publication number CN212713943U, a yarn-winding air-jet loom for smoothing yarn winding includes an air-jet loom body. A weaving frame is fixedly connected to the upper surface of the air-jet loom body, and a tensioning device is fixedly connected to the lower side of the air-jet loom body near the weaving frame. A take-up roller is fixedly connected to the lower side of the air-jet loom body near the tensioning device, and a control console is fixedly connected to one side of the air-jet loom body. A drive motor is fixedly connected to the side of the air-jet loom body near the control console. This utility model relates to the field of textile equipment technology. The smoothing device in this yarn-winding air-jet loom is equipped with two sets of ironing plates with controllable spacing for ironing the woven product. Simultaneously, a smoothing wheel can roll and smooth the woven product, thereby improving product quality. Furthermore, the yarn feeding device has multiple sets of yarn grooves, and a moving plate can confine the yarn within different yarn grooves.
[0004] However, when the yarn is fed into the air-jet loom, the yarn bundle is often pulled, creating traction. When the traction reaches a certain critical point, the yarn bundle will break. Therefore, how to prevent yarn breakage is an urgent problem to be solved. Utility Model Content
[0005] The purpose of this invention is to provide a breakage-proof yarn feeding mechanism for an air-jet loom, which can prevent yarn bundle breakage during the yarn feeding process.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a breakage-proof yarn feeding mechanism for an air-jet loom, comprising a side plate, a track fixedly connected to the inner side of the side plate, a slider slidably connected inside the track, a pulley rotatably connected inside the slider, a limiting groove formed on the inner side of the track, the pulley extending into the limiting groove, a bearing fixedly installed on the outer side of the slider, a rotating shaft rotatably connected inside the bearing, a pay-off roller fixedly connected to one end of the rotating shaft, a yarn ring fixedly connected to the outer side of the pay-off roller, a yarn groove formed inside the yarn ring, and spring seats fixedly connected to the sides of both the slider and the track, with a spring fixedly connected inside the spring seats.
[0007] By adopting the above technical solution, the wire feeding roller is installed inside the bearing via a rotating shaft. The wire harness is then wound into the groove inside the wire ring. There are multiple wire rings and grooves, allowing multiple sets of wire harnesses to be fed simultaneously. The wire feeding roller can rotate via the bearing. When the wire harness generates traction force, the slider will slide inside the track. The displacement of the slider can release the traction force of the wire harness. The slider and the track are connected by a spring. When the slider moves to the end of the track, the contraction of the spring can generate tension between the slider and the track. This not only prevents the wire harness from breaking during the feeding process but also achieves a tensioning effect, preventing the wire harness from wrinkling. Furthermore, when the slider is displaced, the pulley will travel inside the limiting groove, thereby improving the smoothness of the slider during the sliding process.
[0008] A further feature of this invention is that a horizontal plate is fixedly connected to the inner side of the side plate, a guide plate is fixedly connected to the top of the horizontal plate, and a guide wheel is rotatably connected inside the guide plate.
[0009] By adopting the above technical solution, the middle part of the wire harness is connected to the wire wheel inside the wire guide plate, thereby limiting and isolating each wire harness and preventing the phenomenon of crossover and series connection between multiple wire harnesses.
[0010] A further feature of this invention is that the number of guide wheels is several, and each of the several guide wheels is divided into two groups.
[0011] By adopting the above technical solution, since there are multiple wire rings and wire grooves, the two sets of guide wheels are divided into multiple groups.
[0012] A further feature of this invention is that an extension plate is fixedly connected to the outer side of the side plate, and a linear rail is fixedly connected to the inner side of the extension plate.
[0013] By adopting the above technical solution, the extension plate is set on the outside of the side plate, and the linear rail is linear in shape.
[0014] A further feature of this invention is that: both sides of the inner wall of the linear rail are fixedly connected to limit blocks, and a linear plate is slidably connected inside the linear rail.
[0015] By adopting the above technical solution, the linear plate is extended into the interior of the linear rail. When the linear plate comes into contact with the limiting block, the linear plate will be overlapped inside the linear rail.
[0016] A further feature of this invention is that an outer plate is fixedly connected to one side of the linear plate, and a wire hole is provided inside the outer plate.
[0017] By adopting the above technical solution, there are multiple wire holes, and each wire hole is parallel to multiple guide wheels. Each wire bundle extends into the interior of each guide wheel and each wire hole, thereby preventing the phenomenon of crossover and series connection between multiple wire bundles.
[0018] A further feature of this invention is that the number of side plates is two, and the two side plates are symmetrical to each other.
[0019] By adopting the above technical solution, the two ends of the wire feeding roller are supported by two side plates respectively.
[0020] A further feature of this invention is that mounting blocks are fixedly connected to the inner sides of both side plates, and bolts are threaded into the internal parts of the mounting blocks.
[0021] By adopting the above technical solution, the bolt is threaded into the interior of the mounting block, so that the bolt extends into the base surface, thereby fixing the side plate in the base surface.
[0022] A further feature of this invention is that the number of bolts is four, and an anti-slip pad is fitted onto the middle of each of the four bolts.
[0023] By adopting the above technical solution, the anti-slip pad increases friction and prevents the bolts from falling off.
[0024] A further feature of this invention is that lighting lamps are provided on the outer sides of both side plates.
[0025] By adopting the above technical solution, the lighting provides illumination, making it easier for staff to observe the wiring process.
[0026] The beneficial effects of this utility model are:
[0027] 1. This utility model, through the arrangement of side plates, tracks, sliders, pulleys, limiting grooves, bearings, rotating shafts, wire feeding rollers, wire rings, wire grooves, spring seats, and springs, allows the wire feeding rollers to be installed inside the bearings via rotating shafts. The wire harness is then wound into the wire groove inside the wire ring. Multiple wire rings and grooves are used, enabling simultaneous feeding of multiple wire harnesses. The wire feeding rollers rotate via the bearings. When the wire harness generates traction, the slider slides inside the track. The displacement of the slider releases the traction force on the wire harness. The slider and track are connected by springs. When the slider moves to the end of the track, the spring's contraction generates tension between the slider and the track, preventing wire harness breakage and achieving tension during feeding, thus preventing wire harness wrinkles. Furthermore, as the slider moves, the pulley travels inside the limiting groove, improving the smoothness of the slider's movement.
[0028] 2. This utility model, through the arrangement of a horizontal plate, a guide plate, a guide wheel, an extension plate, a linear guide, a limiting block, a linear plate, an outer plate, and wire holes, allows the middle part of the wire harness to overlap with the guide wheel inside the guide plate, thereby limiting and isolating each wire harness and preventing multiple wire harnesses from intersecting or being connected in series. The linear plate extends into the interior of the linear guide, and when the linear plate contacts the limiting block, the linear plate will overlap into the interior of the linear guide. There are multiple wire holes, and each wire hole is parallel to multiple guide wheels. Each wire harness extends into the interior of each guide wheel and each wire hole, thereby preventing multiple wire harnesses from intersecting or being connected in series.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0036] Reference Figure 1-4A breakage-proof yarn feeding mechanism for an air-jet loom includes a side plate 1. A track 2 is fixedly connected to the inner side of the side plate 1. A slider 3 is slidably connected inside the track 2. A pulley 4 is rotatably connected inside the slider 3. A limit groove 5 is formed on the inner side of the track 2, and the pulley 4 extends into the limit groove 5. A bearing 6 is fixedly installed on the outer side of the slider 3. A rotating shaft 7 is rotatably connected inside the bearing 6. A pay-off roller 8 is fixedly connected to one end of the rotating shaft 7. A yarn loop 9 is fixedly connected to the outside of the pay-off roller 8. A yarn groove 10 is formed inside the yarn loop 9. Spring seats 11 are fixedly connected to the sides of both the slider 3 and the track 2. A spring 12 is fixedly connected inside the spring seat 11. The pay-off roller 8 is installed into the bearing 6 via the rotating shaft 7, and then the yarn bundle is wound into the yarn groove 10 inside the yarn loop 9. There are multiple wire loops 9 and wire grooves 10, enabling simultaneous feeding of multiple wire harnesses. The feeding roller 8 rotates via bearing 6. When the wire harness generates traction, the slider 3 slides inside the track 2. The displacement of the slider 3 releases the traction force of the wire harness. The slider 3 and the track 2 are connected by a spring 12. When the slider 3 moves to the end of the track 2, the contraction of the spring 12 generates tension between the slider 3 and the track 2, preventing wire harness breakage and achieving tension during feeding to prevent wrinkles. During the displacement of the slider 3, the pulley 4 travels inside the limiting groove 5, improving the smoothness of the slider 3's sliding process. The inner side plate 1... A horizontal plate 13 is fixedly connected to the side, and a guide plate 14 is fixedly connected to the top of the horizontal plate 13. A guide wheel 15 is rotatably connected inside the guide plate 14, which overlaps the middle part of the wire bundle with the guide wheel 15 inside the guide plate 14, thereby limiting and isolating each wire bundle to prevent the phenomenon of multiple wire bundles crossing or connecting in series. There are several guide wheels 15, and the several guide wheels 15 are divided into two groups. Since there are multiple wire rings 9 and wire grooves 10, the two groups of guide wheels 15 are divided into multiple groups. An extension plate 16 is fixedly connected to the outer side of the side plate 1, and a linear rail 17 is fixedly connected to the inner side of the extension plate 16. The extension plate 16 is located on the outer side of the side plate 1, and the linear rail 17 is linear in shape. Limiting blocks 18 are fixedly connected to both sides of the inner wall of the linear rail 17. A linear plate 19 is slidably connected inside the linear rail 17, extending into the interior of the linear rail 17. When the linear plate 19 contacts the limiting block 18, it will overlap inside the linear rail 17. An outer plate 20 is fixedly connected to one side of the linear plate 19. The outer plate 20 has multiple wire holes 21, which are parallel to multiple guide wheels 15. Each wire bundle extends into each guide wheel 15 and each wire hole 21, thus preventing the wire bundles from intersecting or connecting in series. There are two side plates 1, which are symmetrical to each other. The two ends of the feed roller 8 are supported by the two side plates 1, and mounting blocks 22 are fixedly connected to the inner sides of both side plates 1.The mounting block 22 has internal threaded connections for bolts 23. These bolts 23 are threaded into the mounting block 22, extending into the base surface, thus fixing the side plate 1 to the base surface. There are four bolts 23, and anti-slip washers are fitted around the center of each bolt 23. These washers increase friction and prevent the bolts 23 from falling off. Lighting is installed on the outer sides of both side plates 1 to provide illumination, facilitating observation of the wiring process by workers.
[0037] In this invention, the feed roller 8 is installed inside the bearing 6 via the rotating shaft 7. The wire harness is then wound into the groove 10 inside the wire ring 9. Multiple wire rings 9 and grooves 10 are used, allowing for simultaneous feed of multiple wire harnesses. The feed roller 8 rotates via the bearing 6. When the wire harness generates traction, the slider 3 slides inside the track 2. The displacement of the slider 3 releases the traction force on the wire harness. The slider 3 and the track 2 are connected by a spring 12. When the slider 3 moves to the end of the track 2, the contraction of the spring 12 generates tension between the slider 3 and the track 2. This prevents wire harness breakage during feed and also achieves a tensioning effect, preventing wire harness breakage. The slider 3 is folded, and when it is displaced, the pulley 4 will move inside the limiting groove 5, thereby improving the smoothness of the slider 3 during the sliding process. The middle part of the wire harness is connected to the guide wheel 15 inside the guide plate 14, so that each wire harness can be limited and isolated, preventing the phenomenon of multiple wire harnesses crossing or connecting in series. The wire plate 19 is extended into the interior of the wire rail 17. When the wire plate 19 contacts the limiting block 18, the wire plate 19 will be connected to the interior of the wire rail 17. There are multiple wire holes 21, and the multiple wire holes 21 are parallel to multiple guide wheels 15 respectively. Each wire harness extends into the interior of each guide wheel 15 and each wire hole 21, thereby preventing the phenomenon of multiple wire harnesses crossing or connecting in series.
