[0024] The utility model is further described below in conjunction with embodiments.

[0025] Embodiment 1:

[0026] See also Figure 1-Figure 5 The cleaning assembly 5 includes a connecting column 51 fixedly connected to the bottom end of the top plate 4, a first mounting frame 52 fixedly connected to the bottom end of the connecting column 51, a cleaning roller 53 movably arranged inside the first mounting frame 52, a fixing block 54 rotatably connected to one end of the cleaning roller 53, a bolt 55 threadedly connected between the fixing block 54 and the first mounting frame 52, a nut 56 threadedly connected to the outer surface of the bolt 55, and a dust sticking film 57 movably arranged on the outer surface of the cleaning roller 53. The cleaning roller 53 is movably arranged inside the first mounting frame 52, so that when the non-woven fabric passes through, the dust, impurities and fibers on its surface are effectively rolled and adhered to by the dust sticking film 57, thereby ensuring the cleanliness of the non-woven fabric before indentation. When the stickiness of the surface of the dust sticking film 57 is weakened or covered with too many impurities, the nut 56 and the bolt 55 are removed, the fixing block 54 is separated from the first mounting frame 52 and the cleaning roller 53 is removed, so that the old dust sticking film 57 can be removed and replaced with a new one. The disassembly and assembly are simple, and the maintenance cost is reduced.

[0027] A through slot 41 is provided on the upper surface of the top plate 4, and the indentation assembly 6 includes a bidirectional threaded rod 61 movably arranged inside the through slot 41, a connecting frame 62 threadedly connected to the outer surface of the bidirectional threaded rod 61, a first motor 63 fixedly connected to one side of the top plate 4, a second mounting frame 64 fixedly connected to the bottom end of the connecting frame 62, an indentation roller 65 movably arranged inside the second mounting frame 64, and a rotating shaft 66 rotatably connected between the indentation roller 65 and the second mounting frame 64. One end of the bidirectional threaded rod 61 is rotatably connected to the inner wall of the through slot 41, and the other end of the bidirectional threaded rod 61 passes through the through slot 41 and is fixedly connected to the output end of the first motor 63. The bidirectional threaded rod 61 is driven to rotate by the first motor 63, and the rotation of the bidirectional threaded rod 61 drives the connecting frame 62 to move, thereby driving the second mounting frame 64 and the indentation roller 65 to rotate along the bidirectional threaded rod 61, so as to facilitate the rapid adjustment of the indentation roller 65 according to non-woven fabrics of different sizes and different indentation requirements.

[0028] A support groove 3 is fixedly connected to one side of the workbench 1, and the support groove 3 is provided with two groups, one group of support grooves 3 is fixedly connected with a slide rod 7 inside, and a first slide block 71 is slidably connected to the outer surface of the slide rod 7, and a second motor 31 is fixedly connected to the top of the other group of support grooves 3, and a one-way threaded rod 8 is fixedly connected to the output end of the second motor 31. The one-way threaded rod 8 rotates and passes through the other group of support grooves 3, and a second slide block 81 is threadedly connected to the outer surface of the one-way threaded rod 8. The top plate 4 is fixedly connected between the first slide block 71 and the second slide block 81, and the one-way threaded rod 8 is driven to rotate by the second motor 31, and the rotation of the one-way threaded rod 8 drives the second slide block 81 to move up and down. At this time, the first slide block 71 slides up and down along the slide rod 7, thereby realizing the automatic adjustment of the height of the top plate 4, which is convenient for adjusting the height of the indentation component 6 and the cleaning component 5.

[0029] The lowest end of the creasing roller 65 is parallel to the lowest end of the cleaning roller 53 and is located on the same horizontal line. When the height or position needs to be adjusted, only the height of the top plate 4 needs to be adjusted to ensure the proper position of the creasing roller 65 and the cleaning roller 53 at the same time, which improves the convenience of work.

[0030] The conveying assembly 2 includes a first fixed frame 21 and a second fixed frame 22 fixedly connected to the top of the workbench 1, a first rotating rod 23 rotatably connected to the inner side of the first fixed frame 21, a third motor 25 fixedly connected to the outer side of the first fixed frame 21, a second rotating rod 24 rotatably connected to the inner side of the second fixed frame 22, and a conveyor belt 26 transmission-connected between the first rotating rod 23 and the second rotating rod 24. The first rotating rod 23 passes through the first fixed frame 21 and is fixedly connected to the output end of the third motor 25. The third motor 25 is started, and the third motor 25 drives the first rotating rod 23 to rotate. At this time, the transmission connection of the conveyor belt 26 is realized under the rotation cooperation of the first rotating rod 23 and the second rotating rod 24 to convey the non-woven fabric.

[0031] A support plate 9 is fixedly connected to the top of the workbench 1, and a rotating rod 91 is rotatably connected to the inner side of the support plate 9. The rotating rod 91 is arranged below the conveyor belt 26. The rotating rod 91 is located below the conveyor belt 26 to provide auxiliary guidance for the non-woven fabric during the conveying process, and also plays a supporting role during the indentation process.

[0032] When in use, the non-woven fabric is placed on the top of the conveyor belt 26, and the one-way threaded rod 8 is driven to rotate by the second motor 31. The rotation of the one-way threaded rod 8 drives the second slider 81 to move up and down. At this time, the first slider 71 slides up and down along the slide rod 7 to adjust the height of the indentation assembly 6 and the cleaning assembly 5, so that the indentation roller 65 and the cleaning roller 53 are in contact with the non-woven fabric. The second mounting frame 64 and the indentation roller 65 are driven by the first motor 63 to rotate along the bidirectional threaded rod 61. The indentation roller 65 is quickly adjusted according to non-woven fabrics of different sizes and different indentation requirements. After the adjustment is completed, the third motor 25 is started, and the third motor 25 drives the first rotating rod 23 to rotate. At this time, the first rotating rod 23 and the second rotating rod 24 realize the transmission connection of the conveyor belt 26 to convey the non-woven fabric. During the transmission process, the non-woven fabric first passes through the bottom end of the cleaning roller 53. The cleaning roller 53 effectively rolls when the non-woven fabric passes through and adheres to the dust, impurities and fibers on its surface through the sticky film 57, thereby ensuring the cleanliness of the non-woven fabric before indentation. The indentation treatment is then performed through the bottom end of the indentation roller 65. When the viscosity of the sticky film 57 surface is weakened or covered with too many impurities, the nut 56 and the bolt 55 are removed, the fixing block 54 is separated from the first mounting frame 52 and the cleaning roller 53 is removed, so that the old sticky film 57 can be removed and replaced with a new one. The disassembly and assembly are simple, and the maintenance cost is reduced.
