Description

Technical Field

[0001] The utility model relates to the technical field of air jet looms, in particular to an anti-wrinkle device for cotton air jet looms. Background Art

[0002] Air jet loom is a shuttleless loom that uses jet air to pull the weft yarn through the shed. The working principle is to use air as the weft insertion medium, and the ejected compressed air flow generates friction traction on the weft yarn to pull it through the shed, and the purpose of weft insertion is achieved through the jet generated by the air jet.

[0003] After searching, the Chinese patent publication number CN220867646U discloses an anti-wrinkle device for air-jet looms. The technical point is: it solves the problem that in the severe cold weather in winter, the temperature of the fabric produced by the air-jet loom is low, and it is easy to be folded and wrinkled during the transportation process. In addition, the fabric itself is also prone to wrinkles due to factors such as friction and curling, which affects the overall quality of the fabric.

[0004] However, during the implementation of the above scheme, when the cotton cloth is being transferred, it may become loose or tense. Since the flattening mechanism in the above scheme is a fixed component, the height of the flattening mechanism cannot be adaptively adjusted according to the looseness of the cotton cloth during transfer. It cannot be guaranteed that the flattening mechanism will always hold the cotton cloth tight, which will still cause wrinkles in the cotton cloth.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0006] In view of the above background technology, the existing technology has the problem that it cannot adaptively adjust the height of the flattening mechanism according to the slackness of the cotton cloth during transmission, and cannot ensure that the flattening mechanism always holds the cotton cloth tight, which still causes the cotton cloth to wrinkle.

[0007] The utility model discloses an anti-wrinkle device for a cotton air-jet loom, comprising two square blocks and a stretching roller, the inner wall of each square block is provided with two sliding grooves, the inner wall of each sliding groove is slidably connected to a sliding block, the inner wall of each square block is in sliding contact with a connecting block, the left side and the right side of each connecting block are fixedly connected to the outer surface of the corresponding sliding block, the bottom surface of each connecting block is fixedly connected to a spring and a guide rod, the bottom end of each spring is fixedly connected to the inner bottom wall of the corresponding square block, the outer surface of each guide rod is slidably connected to the inner wall of the corresponding square block, and the inner wall of each connecting block is rotatably connected to the outer surface of the stretching roller.

[0008] Furthermore, the outer surface of each square block is fixedly connected to a cross bar, and a limiting groove is provided on a side of each cross bar that is close to each other, and the inner wall of each limiting groove is in sliding contact with the outer surface of the stretching roller.

[0009] Furthermore, a connecting piece is fixedly mounted on the upper surface of each cross bar, an electromagnetic heating roller is provided on the right side of the stretching roller, and an inner wall of each connecting piece is mounted on the outer surface of the electromagnetic heating roller.

[0010] Furthermore, the bottom surface of each cross bar is fixedly connected to two vertical poles, and a base plate and two connecting frames are provided below the stretching roller. The bottom end of each vertical pole is fixedly connected to the upper surface of the base plate, and the outer surface of each connecting frame is fixedly connected to the outer surface of the corresponding vertical pole.

[0011] Furthermore, the left sides of the two uprights are fixedly connected to support frame 1 and support frame 2, and the bottom surface of each support frame 1 is fixedly connected to the upper surface of the corresponding support frame 2.

[0012] Furthermore, a tensioning roller and two guide rollers are provided on the left side of the stretching roller, and the outer surface of each guide roller and tensioning roller is rotatably connected to the inner wall of the corresponding support frame 1 and support frame 2.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. The utility model provides a square block, a sliding block, a connecting block, a spring, a guide rod and other components. By providing a square block and opening a sliding groove, the sliding block is placed inside the square block. When the cotton cloth becomes loose during the transmission process, the spring and the guide rod provided on the bottom surface of the connecting block are used to make the corresponding connecting block rise and contact with the cotton cloth to tighten the cotton cloth. Thus, the device can adapt to the looseness of the cotton cloth during transmission by providing a spring, so that the stretching roller is always tight with the cotton cloth to prevent the cotton cloth from wrinkling due to looseness during transmission.

[0016] 2. The utility model sets up square blocks, connecting blocks, stretching rollers, electromagnetic heating rollers, connecting pieces and other components. The square blocks are set to provide moving space for the connecting blocks.
