Description

Technical Field

[0001] This utility model relates to the field of textile machinery parts technology, specifically a steel reed for a rapier loom. Background Technology

[0002] As a key core component of rapier looms, the reed plays a crucial role in determining the fabric width, tightening the weft yarns to form the fabric, and guiding the warp yarns to arrange themselves according to a predetermined pattern. Its performance directly affects the weaving quality and production efficiency of the fabric.

[0003] In existing rapier looms, the reed teeth and reed beams of steel reeds are mostly fixedly connected by welding or integral molding. When some reed teeth are damaged, it is impossible to replace the damaged reed teeth individually; the entire steel reed must be replaced, which significantly increases production costs and equipment downtime. Furthermore, the reed teeth are usually made of a single metal material. During long-term high-speed weaving, the reed teeth will experience continuous friction and impact with the warp and weft yarns, which can easily lead to wear and deformation of the reed teeth. This not only shortens the service life of the steel reed but also scratches the warp and weft yarns, causing quality defects such as broken yarns and fuzz in the fabric. Therefore, it is necessary to design a steel reed for rapier looms to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a steel reed for a rapier loom to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel reed for a rapier loom, comprising a lower reed beam and an upper reed beam, wherein an end beam is fixedly connected to the outer side of the upper end of the lower reed beam, and an upper reed beam is fixedly connected to the upper end of the end beam; reed teeth are provided between the lower reed beam and the upper reed beam, and an mounting strip is provided on the outer side of the upper end of the reed teeth; the mounting strip is slidably connected to the upper reed beam; a limit rod is slidably connected to the inner side of the upper reed beam, and the limit rod is slidably connected to the mounting strip; A first rubber pad is fixedly connected to the lower end face of the upper reed beam, and a second rubber pad is fixedly connected to the upper end face of the lower reed beam. Both the first and second rubber pads are slidably connected to the reed teeth.

[0006] Preferably, both the lower reed beam and the upper reed beam have mounting slots inside. The shape and size of the mounting slot on the upper side correspond to the shape and size of the mounting clip, and the shape and size of the mounting slot on the lower side correspond to the shape and size of the reed teeth.

[0007] Preferably, the lower end face of the mounting strip is provided with an embedding groove, and the inner side of the embedding groove is provided with an anti-slip pad, which fits against the reed teeth.

[0008] Preferably, the upper reed beam has a disassembly end on the inner side of its left end, the front end of the disassembly end has a hexagonal insertion hole, the right end of the disassembly end is fixedly connected to a threaded end, the threaded end is fixedly connected to a limiting insertion rod, and the threaded end is spirally connected to the upper reed beam.

[0009] Preferably, a disassembly pad is slidably connected at the middle position inside the lower reed beam. The upper end face of the disassembly pad fits against the lower end face of the reed teeth. A push rod is fixedly connected to the lower end of the disassembly pad, and the push rod is slidably connected to the lower reed beam.

[0010] Preferably, the surface of the reed teeth is provided with a wear-resistant coating, and the wear-resistant coating is made of tungsten carbide.

[0011] Preferably, the lower reed beam, end beam, and upper reed beam are all made of high-strength aluminum alloy, and the surfaces of the lower reed beam, end beam, and upper reed are all provided with an anodized layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The steel reed used in this rapier loom can be inserted into the disassembly end using a hex wrench, which can be rotated to disconnect the threaded end from the upper reed beam. This allows the limiting rod to be removed from the upper reed beam, thus freeing the mounting clip. Pushing the push rod moves the disassembly pad upwards, which in turn moves the reed teeth upwards and removes the mounting clip from the upper reed beam. This facilitates individual replacement of damaged reed teeth without requiring complete reed replacement, significantly reducing maintenance costs and equipment downtime, and improving the economic efficiency of the equipment.

[0013] 2. The steel reed used in this rapier loom protects the inner end faces of the upper and lower reed beams through the action of the first and second rubber pads. The wear-resistant coating on the surface of the reed teeth provides wear-resistant protection to the outer surface of the reed teeth and avoids quality defects such as broken yarns and fuzz caused by friction with the warp and weft yarns. The anodized layer improves the corrosion resistance of the lower reed beam, end beams and upper reed beam, extending their service life. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 Please refer to Figure 1-6 As shown, this utility model provides a steel reed for a rapier loom, including a lower reed beam 1 and an upper reed beam 3. An end beam 2 is fixedly connected to the outer side of the upper end of the lower reed beam 1, and the upper reed beam 3 is fixedly connected to the upper end of the end beam 2. A reed tooth 4 is provided between the lower reed beam 1 and the upper reed beam 3. An installation clip 5 is provided on the outer side of the upper end of the reed tooth 4. The installation clip 5 is slidably connected to the upper reed beam 3. A limit rod 6 is slidably connected to the inner side of the upper reed beam 3. The limit rod 6 is slidably connected to the installation clip 5. By removing the limit rod 6, the installation clip 5 can be unrestricted, thereby allowing the installation clip 5 and the reed tooth 4 to be removed. This facilitates the individual disassembly and replacement of damaged reed teeth 4, eliminating the need to replace the entire steel reed, significantly reducing maintenance costs and equipment downtime, and improving the economic efficiency of equipment use. A first rubber pad 7 is fixedly connected to the lower end face of the upper reed beam 3, and a second rubber pad 8 is fixedly connected to the upper end face of the lower reed beam 1. Both the first rubber pad 7 and the second rubber pad 8 are slidably connected to the reed teeth 4. The inner end faces of the upper reed beam 3 and the lower reed beam 1 can be protected by the function of the first rubber pad 7 and the second rubber pad 8.

[0018] Specifically, both the lower reed beam 1 and the upper reed beam 3 have mounting slots 9 inside. The shape and size of the upper mounting slot 9 correspond to the shape and size of the mounting clip 5, and the shape and size of the lower mounting slot 9 correspond to the shape and size of the reed teeth 4. The mounting slots 9 enable the reed teeth 4 and the mounting clip 5 to be inserted into the lower reed beam 1 and the upper reed beam 3 respectively.

[0019] Specifically, the lower end face of the mounting strip 5 is provided with an embedding groove 10, and the inner side of the embedding groove 10 is provided with an anti-slip pad 11. The anti-slip pad 11 and the reed teeth 4 fit together. Through the action of the embedding groove 10, the upper end of the reed teeth 4 can be inserted into the inner side of the mounting strip 5, and the anti-slip pad 11 is used to perform anti-slip installation treatment on the reed teeth 4.

[0020] Specifically, a disassembly end 12 is provided on the inner side of the left end of the upper reed beam 3. A hexagonal insertion hole is provided on the front end face of the disassembly end 12. A threaded end 13 is fixedly connected to the right end of the disassembly end 12. The threaded end 13 is fixedly connected to the limiting rod 6. The threaded end 13 is spirally connected to the upper reed beam 3. A hexagonal wrench can be inserted into the inner side of the disassembly end 12. By rotating the hexagonal wrench, the disassembly end 12 can be rotated, which in turn drives the threaded end 13 to rotate. This allows the threaded end 13 to spirally move out of the upper reed beam 3. After the threaded end 13 moves out, the left end of the limiting rod 6 is no longer restricted, allowing the limiting rod 6 to move out of the upper reed beam 3.

[0021] Specifically, a disassembly pad 14 is slidably connected at the middle position inside the lower reed beam 1. The upper end face of the disassembly pad 14 is in contact with the lower end face of the reed tooth 4. A push rod 15 is fixedly connected to the lower end of the disassembly pad 14. The push rod 15 is slidably connected to the lower reed beam 1. By pushing the push rod 15, the disassembly pad 14 can move upward, thereby causing the reed tooth 4 to be pushed upward.

[0022] Specifically, the surface of the reed teeth 4 is provided with a wear-resistant coating 16, which is made of tungsten carbide. The wear-resistant coating 16 on the surface of the reed teeth 4 can provide wear-resistant protection for the outer surface of the reed teeth 4, and at the same time can prevent the fabric from having quality defects such as broken filaments and fuzz due to friction with the warp and weft yarns.

[0023] Specifically, the lower reed beam 1, end beam 2, and upper reed beam 3 are all made of high-strength aluminum alloy. The surfaces of the lower reed beam 1, end beam 2, and upper reed are all provided with an anodized layer 17. The anodized layer 17 can improve the corrosion resistance of the lower reed beam 1, end beam 2, and upper reed beam 3 and extend their service life.

[0024] Working Principle: This utility model is a steel reed for a rapier loom. When in use, the first rubber pad 7 and the second rubber pad 8 protect the inner end faces of the upper reed beam 3 and the lower reed beam 1. The wear-resistant coating 16 on the surface of the reed teeth 4 provides wear-resistant protection to the outer surface of the reed teeth 4, preventing quality defects such as broken threads and fuzz caused by friction with the warp and weft yarns. The anodized layer 17 improves the corrosion resistance of the lower reed beam 1, end beam 2, and upper reed beam 3, extending their service life. When a damaged reed tooth 4 appears inside the steel reed, a hexagonal wrench can be inserted into the disassembly end 12. Rotating the hexagonal wrench rotates the disassembly end 12, causing the threaded end 1 to rotate. 3. Rotate the upper reed beam 3 so that the threaded end 13 can be spirally moved out of the upper reed beam 3. After the threaded end 13 is moved out, the left end of the limiting rod 6 is unrestricted, so that the limiting rod 6 can be moved out of the upper reed beam 3. The mounting clip 5 is unrestricted, and the push rod 15 is pushed to move the disassembly pad 14 upward, so that the reed tooth 4 can be pushed upward and moved, and the mounting clip 5 can be moved out of the upper reed beam 3. The damaged reed tooth 4 is pulled out of the mounting clip 5, and the new reed tooth 4 is installed in the mounting clip 5. This allows the damaged reed tooth 4 to be replaced individually without replacing the entire reed, which greatly reduces maintenance costs and equipment downtime and improves the economic efficiency of the equipment.
