[0031] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0032] like Figure 1As shown in Figure 3, a nonwoven fabric drying device according to one embodiment of the present invention includes a frame 1, a main conveyor roller device 2, a first drying device 3, a second drying device 4, and a winding device 5. The main conveyor roller device 2 is mounted on the frame 1. The first drying device 3 includes a first auxiliary conveyor roller mechanism 31 and a heating mechanism 32. The first auxiliary conveyor roller mechanism 31 is mounted on the frame 1, and the heating mechanism 32 is mounted on the first auxiliary conveyor roller mechanism 31. The heating mechanism 32 is used to heat the first auxiliary conveyor roller mechanism 31, which is used to support and dry one side of the nonwoven fabric. The second drying device 4 is mounted on the frame 1 and is used to dry the other side of the nonwoven fabric. The winding device 5 is mounted on the frame 1 and is used to wind up the nonwoven fabric.

[0033] The aforementioned nonwoven fabric drying equipment, by setting up a dedicated first drying device 3 (drying the back side) and a second drying device 4 (drying the front side), can simultaneously and independently and efficiently dry both sides of the nonwoven fabric, significantly shortening the overall drying time and improving production efficiency. It avoids the problems of low efficiency and uneven drying on both sides found in traditional hot air ovens. The heating mechanism 32 directly heats the first auxiliary conveyor roller; when one side of the nonwoven fabric is in close contact with the heated roller surface, heat is directly and efficiently transferred to the nonwoven fabric through heat conduction. This nonwoven fabric drying equipment solves the problem of inconsistent drying on both sides of the nonwoven fabric in traditional equipment.

[0034] like Figure 1As shown in Figure 2, in one embodiment, the main conveying roller device 2 includes a power mechanism 21, a first support frame 22, a first roller 23, a second roller 24, and a third roller 25; the first roller 23, the second roller 24, and the third roller 25 are all mounted on the first support frame 22 and rotatably connected to the first support frame 22; the first roller 23 and the third roller 25 are used to support one side of the nonwoven fabric, and the second roller 24 is used to press down on the other side of the nonwoven fabric; the output end of the power mechanism 21 is respectively connected to the first roller 23 and the third roller 25 for transmission, and the power mechanism 21 is used to drive the first roller 23 and the third roller 25 to rotate; the power mechanism 21 includes a first gear 211, a second gear 212, a third gear 213, a fourth gear 214, and a first motor 215. The first motor 215 is mounted on the frame 1, and the first gear 211 is mounted on the output end of the first motor 215, which drives the first gear 211 to rotate. The second gear 212 is sleeved on one end of the first roller 23, and the third gear 213 is mounted on the first support frame 22 and rotatably connected to it. The fourth gear 214 is sleeved on one end of the third roller 25. The first gear 211, second gear 212, third gear 213, and fourth gear 214 mesh sequentially. Thus, the first roller 23 and third roller 25 support the lower surface of the nonwoven fabric, while the second roller 24 presses down on the upper surface, forming an S-shaped path. This effectively tensions the nonwoven fabric, preventing deviation and wrinkles, and ensuring smooth conveying.

[0035] like Figure 1As shown in Figure 3, in one embodiment, the first auxiliary conveying roller mechanism 31 includes a fourth roller 311, a second motor 312, a gearbox 313, and a rack 314; the second motor 312 is connected to the gearbox 313, a fifth gear is provided on the output end of the gearbox 313, the outer contour of the rack 314 is arranged in a circular shape, the rack 314 is provided on one end face of the fourth roller 311, and the fifth gear meshes with the rack 314; the second motor 312 and the gearbox 313 are both provided on the frame 1; the heating mechanism 32 includes a second support frame 321 and a blower 322, the second support frame 321 is provided with On the frame 1, a through hole is provided on one end face of the fourth roller 311, and the central axis of the fourth roller 311 passes through the through hole. The blower 322 is mounted on the second support frame 321, and the output end of the blower 322 is aligned with the through hole. A heating wire is provided on the air inlet of the blower 322. A track 315 is provided on the first end of the fourth roller 311. The outer contour of the track 315 is arranged in a circular shape. A first roller 316 and a second roller are provided on the frame 1. The first roller 316 and the second roller are slidably connected to the track 315. The first roller 316 and the second roller cooperate to support the track 315. Thus, by using the fourth roller 311 as the first auxiliary conveying roller, its large-diameter surface provides a large area and stable heat-conducting surface for the back of the nonwoven fabric, significantly improving heat transfer efficiency and drying uniformity. The hot air generated by the heating mechanism 32 (blower 322 + heating wire) is directly blown into the inner cavity of the fourth roller 311 through the through hole on the end face of the roller, uniformly heating the roller wall from the inside, resulting in high thermal efficiency and uniform heating. The annular track 315 on the end face of the roller is slidably connected with the first roller 316 and the second roller on the frame 1, providing stable and low-friction rotational support for the large, heated fourth roller 311, preventing deformation and vibration, and ensuring smooth and reliable operation.

[0036] like Figure 1 As shown, in one embodiment, the second drying device 4 includes a third support frame 41, a blower 42, and a heating block 43. The third support frame 41 is mounted on the frame 1, the blower 42 is mounted on the third support frame 41, and the heating block 43 is located at the air inlet of the blower 42. Thus, by using the blower 42 in conjunction with the heating block 43 (which generates hot air), the upper surface (front side) of the nonwoven fabric is directly and centrally dried, achieving convection heating, which complements the contact heat conduction of the lower surface.

[0037] like Figure 1As shown, in one embodiment, the winding device 5 includes a fifth roller 51, a fourth support block 52, and a third motor 53. The third motor 53 and the fourth support block 52 are mounted on the frame 1. The fifth roller 51 is mounted on the fourth support block 52 and rotatably connected to it. The output end of the third motor 53 is connected to the fifth roller 51. Thus, by rotating the fifth roller 51 on the fourth support block 52 and being directly driven by the third motor 53, stable and controllable winding power is provided for the dried nonwoven fabric, ensuring neat winding of the finished product.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
