Description

Technical Field

[0001] This utility model relates to the field of textile technology, specifically to an anti-wrinkle device for a textile air-jet loom. Background Technology

[0002] The air-jet loom is a modern textile machine that uses a high-speed airflow to pull the weft yarn through the warp yarn to complete the weaving process. Its core principle is to use nozzles to spray compressed air, propelling the weft yarn quickly through the shed, thus achieving efficient weaving. Air-jet looms are characterized by high speed, high output, and a high degree of automation. They are suitable for producing a variety of fabrics, especially for large-volume, high-quality textile manufacturing. Compared to traditional looms, air-jet looms are quieter, consume less energy, and reduce yarn wear, thus improving fabric quality. Due to their efficiency and flexibility, air-jet looms are widely used in the modern textile industry, becoming an important tool for improving production efficiency and product quality. During the weaving process, multiple rollers rotate and wind the fabric. If the fabric between two rollers sags during winding, it is prone to folding, resulting in creases. Creases affect the appearance of the product and impact subsequent processing of the finished product. Utility Model Content

[0003] The purpose of this invention is to provide an anti-wrinkle device for textile air-jet looms to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wrinkle-resistant device for a textile air-jet loom, characterized in that it comprises;

[0006] There are two positioning frames, with a gap between each pair of positioning frames, and two adjusting rods, with both ends of the adjusting rods slidingly connected through the two positioning frames. Each positioning frame has an integrally fixed frame at its top. There are two force-bearing rods, with the bottom of the force-bearing rods hinged to the positioning frames. There is a bracket between the two force-bearing rods, with both ends of the bracket (202) slidingly connected through the force-bearing rods. The scraper is located on the side of the bracket.

[0007] There are two tension springs B. Each tension spring B has a movable shaft connected to both ends. The end of the movable shaft away from the tension spring B is connected to the upper connecting rod. The movable shaft is rotatably connected to the upper connecting rod, and the upper connecting piece is sleeved on the outside of the upper connecting rod, while the movable shaft is sleeved on the outside of the lower connecting rod.

[0008] The inner side of the positioning frame has an integrally fixed lower limit shaft, which passes through the lower connector and is hinged to it. The inner side of the force-bearing rod has an integrally fixed upper limit shaft, which passes through the upper connector and is hinged to it.

The ends of the two positioning frames abut against each other to clamp and limit the position. Rotating sleeve B causes sleeve A to clamp the adjusting rod, thereby clamping and limiting the position of the adjusting rod. This method is suitable for machines with different bottom spacing.

[0016] 2. Rotating the upper connecting piece can adjust the length of the upper connecting rod extending out of the threaded tube, thereby adjusting the tension of the tension spring B. By adjusting the angle between the force-bearing rod and the fixed frame, the height of the scraper can be adjusted, making it suitable for machines of different heights.

[0017] 3. Tension spring A tightens the pull plate, causing the telescopic rod to push the scraper rod tightly against the outside of the fabric, making the fabric taut. The taut fabric is wound more evenly, preventing creases caused by folds in the fabric. High-temperature steam is delivered to the inside of the scraper rod by a high-temperature steam engine, thereby removing wrinkles from the fabric. Attached Figure Description

[0025] Please see Figure 1-3 This utility model provides a technical solution: a wrinkle-resistant device for a textile air-jet loom, comprising;

[0026] The fabric flattening assembly includes a positioning frame 100, an adjusting rod 104, a force-bearing rod 200, a scraper rod 400, an upper connecting rod 500, a lower connecting rod 501, a tension spring B503, an upper connector 600, and a lower connector 602.

[0027] There are two positioning frames 100, with a gap between each pair of positioning frames 100. There are also two adjusting rods 104, with both ends of the adjusting rods 104 slidably connected through the two positioning frames 100. Each positioning frame 100 has an integrally fixed fixing frame 105 at its top. There are also two force-bearing rods 200, with the bottom of the force-bearing rods 200 hinged to the positioning frame 100. There is a bracket 202 between the two force-bearing rods 200, with both ends of the bracket 202 slidably connected through the force-bearing rods 200. The scraper 400 is located on the side of the bracket 202.

[0028] There are two tension springs B503. Each tension spring B503 has a movable shaft 502 connected to both ends. The end of the movable shaft 502 away from the tension spring B503 is connected to the upper connecting rod 500. The movable shaft 502 is rotatably connected to the upper connecting rod 500. The upper connecting piece 600 is sleeved on the outside of the upper connecting rod 500, and the movable shaft 502 is sleeved on the outside of the lower connecting rod 501.

[0029] The positioning frame 100 has an integrally fixed lower limit shaft 101 on its inner side, which passes through the lower connector 602 and is hinged thereto. The force rod 200 has an integrally fixed upper limit shaft 201 on its inner side, which passes through the upper connector 600 and is hinged thereto.

[0030] Furthermore, one end of the positioning frame 100 is outwardly flared, and one end of the positioning frame 100 is attached to the inner side of the air jet loom base. The ends of the two positioning frames 100 abut against each other to clamp and limit the position.

[0031] Furthermore, each positioning frame 100 has multiple integrally fixed sleeves A102 on its outer side. Each sleeve A102 has an external thread and a through groove. A sleeve B103 is fitted on the outer side of each sleeve A102. The sleeve B103 is threadedly connected to the sleeve A102. After the sleeve A102 is fitted on the outer side of the adjusting rod 104, the sleeve B103 is fitted on the sleeve A102. Rotating the sleeve B103 causes the sleeve A102 to clamp the adjusting rod 104, thereby clamping and limiting the adjusting rod 104. The positioning frame 100 can slide on the adjusting rod 104 to adjust the distance between the two positioning frames 100, thus making it suitable for different models of machines.

[0032] Furthermore, the inner side of the scraper 400 has multiple telescopic rods 300 fixedly connected. One end of the telescopic rod 300 passes through the bracket 202 and is slidably connected to it. The end of the telescopic rod 300 away from the scraper 400 has a fixedly connected pull plate 301. The outer side of the telescopic rod 300 is fitted with a tension spring A302. The two ends of the tension spring A302 are fixedly connected to the pull plate 301 and the bracket 202, respectively. By tightening the pull plate 301 through the tension spring A302, the telescopic rod 300 pushes the scraper 400 to stick tightly to the outer side of the fabric, making the fabric taut. The taut fabric is wound more evenly, preventing creases caused by folding of the fabric.

[0033] Furthermore, the outer side of the scraper 400 is arc-shaped, and the arc-shaped structure fits the fabric better. The inside of the scraper 400 is hollow, and multiple air outlets 401 are opened on the outer side of the scraper 400.

By rotating the upper connector 600, the length of the upper connecting rod 500 extending out of the threaded tube 601 can be adjusted, thereby adjusting the tension of the tension spring B503. By adjusting the angle between the force-bearing rod 200 and the fixed frame 105, the height of the scraper 400 can be adjusted, which is suitable for machines of different heights. The lower connector 602 is sleeved with a sleeve C603, which is sleeved on the outside of the lower connecting rod 501 and rotatably connected to it.

[0035] Working principle: When in use, the two positioning frames 100 are adjusted at the distance between the two positioning frames 104 until the ends of the positioning frames 100 are close to the inner side of the air-jet loom base. The ends of the two positioning frames 100 abut against each other to clamp and limit the position. Rotating the sleeve B103 causes the sleeve A102 to clamp the adjusting rod 104, thereby clamping and limiting the adjusting rod 104.

[0036] Subsequently, by rotating the upper connecting piece 600, the length of the upper connecting rod 500 extending out of the threaded tube 601 can be adjusted, thereby adjusting the tension of the tension spring B503. By adjusting the angle between the force-bearing rod 200 and the fixed frame 105, the height of the scraper 400 can be adjusted to suit machines of different heights. By tightening the pull plate 301 with the tension spring A302, the telescopic rod 300 pushes the scraper 400 to press tightly against the outside of the fabric, making the fabric taut. The taut fabric is wound more evenly, preventing creases caused by folds in the fabric. High-temperature steam is delivered to the inside of the scraper 400 by a high-temperature steam generator, thereby removing wrinkles from the fabric.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
