Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing equipment, and particularly relates to an air-expansion shaft for non-woven fabrics. Background Technique

[0002] An air-expansion shaft is a specially designed winding and unwinding shaft, that is, a shaft whose surface can protrude after being inflated under high pressure, and a shaft whose surface part quickly retracts after deflation is called an air-expansion shaft. Its names are diverse, also called pneumatic shaft, expansion shaft, inflation shaft, air-expansion roller, inflatable shaft, pressure shaft, air-expansion roller, etc.

[0003] Traditional air-expansion shafts for non-woven fabrics have some disadvantages. The traditional air-expansion shaft is fixedly installed on the machine frame. When producing non-woven fabrics, workers need to manually pass the non-woven fabric through the surface of the air-expansion shaft. Since the air-expansion shaft is fixed on the machine frame, the space around the air-expansion shaft is small, making it difficult for the non-woven fabric to pass through the surface of the air-expansion shaft, resulting in high labor intensity and long operation time, thus affecting the cutting and processing efficiency of non-woven fabrics. Content of the Utility Model

[0004] The main purpose of the utility model is to provide an air-expansion shaft for non-woven fabrics, which can effectively solve the problems in the background technique.

[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As Figures 1-4 shown, an air-expansion shaft for non-woven fabric includes a frame 1. A regulation mechanism 6 is provided on the inner wall of the inner side of the frame 1. The regulation mechanism 6 includes a fixed frame 61 fixedly connected to the inner wall of the inner side of the frame 1. A guiding groove 62 is opened at one end of the fixed frame 61. An installation ring 63 is slidably connected to the inner side of the fixed frame 61. An air-expansion shaft main body 64 is installed inside the installation ring 63. A sliding block 65 is slidably connected to the inner side of the guiding groove 62. A regulation frame 66 is fixedly connected to the upper end of the fixed frame 61. An adjusting rod 67 is threadedly connected to the inner side of the regulation frame 66. A connecting ring 68 is fixedly connected to the upper end of the installation ring 63. A limiting block 69 is slidably connected inside the connecting ring 68. One end of the sliding block 65 is fixedly connected to a fixing plate 610.

[0022] In this embodiment, a limiting frame 611 is fixedly connected to one end of the regulation frame 66. A limiting plate 612 is slidably connected to the inner side of the limiting frame 611. A fastening bolt 613 is threadedly connected to the inside of the limiting frame 611. The other end of the sliding block 65 is fixedly connected to one end of the installation ring 63. The outer side of the adjusting rod 67 is movably connected to the inner side of the connecting ring 68 near the lower side of the regulation frame 66. The adjusting rod 67 penetrates through the inside of the limiting block 69. A fixed connection is made between the adjusting rod 67 and the limiting block 69. The lower end of the limiting plate 612 is fixedly connected to the upper end of the fixing plate 610. The fastening bolt 613 is in contact with the limiting plate 612.

[0023] Specifically, screw out the fastening bolt 613 from the inside of the limiting frame 611, and then rotate the adjusting rod 67 to make the adjusting rod 67 rotate inside the regulation frame 66 and the connecting ring 68, so that the adjusting rod 67 drives the connecting ring 68 to move upward through the limiting block 69. Furthermore, the connecting ring 68 drives the air-expansion shaft main body 64 to move upward through the installation ring 63. At the same time, the installation ring 63 drives the sliding block 65 to slide inside the guiding groove 62, and the sliding block 65 drives the limiting plate 612 to slide upward inside the limiting frame 611 through the fixing plate 610. Then screw the fastening bolt 613 into the inside of the limiting frame 611 and make the fastening bolt 613 contact the limiting plate 612, and the height of the air-expansion shaft main body 64 can be limited. By rotating the adjusting rod 67, the adjusting rod 67 drives the connecting ring 68 to move upward through the limiting block 69, so that the connecting ring 68 drives the air-expansion shaft main body 64 to move upward through the installation ring 63, and the installation ring 63 drives the sliding block 65 to slide upward inside the guiding groove 62, which can achieve the purpose of facilitating the adjustment of the position of the air-expansion shaft main body 64. Furthermore, there is more space below the air-expansion shaft main body 64, so that it is convenient for the non-woven fabric to pass through the lower side of the air-expansion shaft main body 64.

[0024] In this embodiment, a driving wheel 2 is installed on one side of the inner wall of the frame 1 close to the fixing frame 61, a driven wheel 3 is installed on the other side of the inner wall of the frame 1 close to the fixing frame 61, a placing wheel 4 is installed on the side of the inner wall of the frame 1 close to the driving wheel 2, and a placing plate 5 is fixedly connected to one end of the frame 1. There are multiple groups of driven wheels 3.

[0025] Specifically, wind the non-woven fabric around the outside of the placing wheel 4, then pass the non-woven fabric through the driving wheel 2, then pass the non-woven fabric under the air shaft body 64, and pass the non-woven fabric through the outside of the driven wheel 3, so as to facilitate the slitting of the non-woven fabric.

[0026] Working principle:

[0027] In use, first wind the non-woven fabric around the outside of the placing wheel 4, then screw out the fastening bolt 613 from the inside of the limiting frame 611, and then rotate the adjusting rod 67 so that the adjusting rod 67 rotates inside the regulating frame 66 and the connecting ring 68, causing the adjusting rod 67 to drive the connecting ring 68 to move upward through the limiting block 69. Further, the connecting ring 68 drives the air shaft main body 64 to move upward through the mounting ring 63. At the same time, the mounting ring 63 drives the sliding block 65 to slide inside the guiding groove 62, and the sliding block 65 drives the limiting plate 612 to slide upward inside the limiting frame 611 through the fixing plate 610. Then screw the fastening bolt 613 into the inside of the limiting frame 611 and make the fastening bolt 613 contact the limiting plate 612 to limit the height of the air shaft main body 64. At this time, pass the non-woven fabric through the driving wheel 2, then pass the non-woven fabric under the air shaft main body 64, and pass the non-woven fabric around the outside of the driven wheel 3. Then screw out the fastening bolt 613 and reverse-rotate the adjusting rod 67 to press the air shaft main body 64 downward onto the surface of the non-woven fabric, and then screw the fastening bolt 613 into the inside of the limiting frame 611 to limit the position of the air shaft main body 64. Then start the air shaft main body 64 to inflate the surface of the air shaft main body 64, so that the diameter of the air shaft main body 64 changes, and then the non-woven fabric can be slit. By rotating the adjusting rod 67, the adjusting rod 67 drives the connecting ring 68 to move upward through the limiting block 69, so that the connecting ring 68 drives the air shaft main body 64 to move upward through the mounting ring 63, and the mounting ring 63 drives the sliding block 65 to slide upward inside the guiding groove 62, which can achieve the purpose of facilitating the adjustment of the position of the air shaft main body 64, and further there is more space under the air shaft main body 64 to facilitate the non-woven fabric to pass under the air shaft main body 64. Secondly, the sliding block 65 drives the limiting plate 612 to slide upward inside the limiting frame 611 through the fixing plate 610, and then screw the fastening bolt 613 into the inside of the limiting frame 611, so that the fastening bolt 613 contacts the limiting plate 612, which can achieve the purpose of facilitating the fastening bolt 613 to limit the limiting plate 612 inside the limiting frame 611, and further the position of the air shaft main body 64 can be limited.
