Description

Technical Field

[0001] This utility model relates to the field of flattening device technology, specifically to a flattening device for an acupuncture machine. Background Technology

[0002] In the field of nonwoven fabric production, the needle punching machine, as a core processing equipment, primarily functions to reinforce the fiber web into a finished nonwoven fabric with a certain strength and thickness through needle punching. To address the issue of flatness when the fiber web enters the needle punching machine, the commonly used solution in existing technologies is to install a spreading roller at the machine's inlet. The spreading roller has spreading strips that move to both sides, stretching the nonwoven fabric laterally and thus flattening it. Because the spreading roller needs to be in close contact with the nonwoven fabric surface and generate relative movement during operation, some short fibers and lint on the nonwoven fabric surface easily adhere to the spreading roller surface under friction and electrostatic adsorption. As the production process continues, fibers adhere to the surface of the spreading roller, accumulating over time. If these fibers are not cleaned promptly, they will affect the roller's normal operation: the accumulated fibers alter the roller's surface texture and roughness, reducing friction between the roller and the fiber web, thus decreasing its stretching effect. To ensure the spreading roller's performance, operators need to periodically stop the machine to clean the fibers, increasing labor intensity and potentially interrupting needle punching machine production, reducing the overall efficiency of the nonwoven fabric production line. Therefore, this invention provides a flattening device for a needle punching machine. Utility Model Content

[0003] The purpose of this invention is to provide a flattening device for acupuncture machines.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: A flattening device for a needle punching machine includes: a frame on which two guide rollers and a spreading roller are arranged in a staggered manner, the spreading roller being located on the side of the lower guide roller away from the higher guide roller and having a higher horizontal height than the lower guide roller; the first end of the spreading roller is connected to a drive device. A shaft is rotatably mounted on the frame, located below the spreading roller. Several mounting seats are mounted on the shaft, and overlapping first and second brushes are mounted on the mounting seats. Both the first and second brushes can rotate to contact the spreading roller, with the first brush contacting the spreading roller before the second brush. The bristles of the first brush have a higher hardness than those of the second brush. The second end of the spreading roller is provided with a first gear; the second end of the shaft is provided with a second gear that meshes with the first gear.

[0005] Based on the above scheme and as a preferred embodiment of the above scheme, the diameter of the first gear is smaller than the diameter of the second gear.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme, the diameter of the first gear is less than one-fifth of the diameter of the second gear.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme, the outer covers of the first gear and the second gear are provided with protective isolation covers.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme, the material of the first brush bristles is PA66 or PA610; the material of the second brush bristles is PA6.

[0009] Compared with the prior art, this utility model has the following advantages and beneficial effects: A shaft is provided on one side of the spreading roller, and several sets of brushes are provided on the shaft. By rotating the shaft, the brushes are driven to contact the spreading roller in sequence to remove the fibers adhering to the spreading roller, ensuring that the roller surface of the spreading roller is clean and tidy, thereby ensuring the spreading effect of the spreading roller.

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0016] like Figure 1 As shown, a flattening device for a needle punching machine includes: a frame 1, on which two guide rollers 2 arranged vertically in a staggered manner and a spreading roller 3 are mounted. The spreading roller 3 is located on the side of the lower guide roller 2 away from the higher guide roller 2, and its horizontal height is higher than that of the lower guide roller 2, causing the nonwoven fabric being guided to be conveyed in an S-shape. The first end of the spreading roller 3 is connected to a drive device 4 for transmission to achieve rotation. The spreading roller 3 is an aluminum alloy spreading roller, which is existing technology, and its structure and working principle will not be described in detail here.

[0017] like Figures 2 to 4 As shown, a shaft 5 is rotatably mounted on the frame 1, located below the spreading roller 3. Several mounting seats 6 are evenly arranged circumferentially on the shaft 5. Overlapping first brushes 7 and second brushes 8 are mounted on the mounting seats 6. Both the first brush 7 and the second brush 8 can rotate with the shaft 5 to contact the spreading roller 3, with the first brush 7 contacting the spreading roller 3 before the second brush 8. When the first brush 7 and the second brush 8 contact the spreading roller 3, they can remove fibers from the spreading roller 3. The bristles of the first brush 7 are harder than those of the second brush 8. Because the first brush 7 contacts the spreading roller 3 first, its relatively harder bristles can peel off stubborn fibers. The second brush 8 contacts the spreading roller 3 later, used to remove short, fine fibers, forming a double cleaning effect to ensure cleaning efficiency.

[0018] Preferably, the bristles of the first brush 7 are made of PA66 or PA610, and the bristles of the second brush 8 are made of PA6. PA66 or PA610 has a higher Mohs hardness than PA6, and the nylon bristles are more wear-resistant and durable, which can extend the service life of the bristles.

[0019] like Figure 3 As shown, a first gear 9 is provided at the second end of the spreading roller 3, and a second gear 10 that meshes with the first gear 9 is provided at the second end of the shaft 5. The synchronous rotation of the spreading roller 3 and the shaft 5 is achieved through the meshing of the two gears.

[0020] In this configuration, the diameter of the first gear 9 is smaller than the diameter of the second gear 10; more specifically, the diameter of the first gear 9 is less than one-fifth the diameter of the second gear 10. Different gear diameter ratios allow for different rotational speeds between the spreading roller 3 and the shaft 5. The larger diameter of the second gear 10 reduces the rotational speed of the central tube 5 and the brush.

[0021] The outer covers of the first gear 9 and the second gear 10 are equipped with protective isolation covers 11 to isolate the gear assembly and provide good protection.

[0022] During operation, the nonwoven fabric passes over the spreading roller 3, then under the lower guide roller 2, and finally over the higher guide roller 2 before entering the needle punching machine.

[0023] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
