Description

Technical Field

[0001] This utility model relates to the field of tension adjustment technology, and in particular to a nonwoven fabric winding mechanism with easily adjustable tension. Background Technology

[0002] In the production and processing of nonwoven fabrics, winding is a crucial step. Traditional nonwoven fabric winding mechanisms often suffer from inconvenient tension adjustment. If the tension of the nonwoven fabric is not properly controlled, defects such as wrinkles, loosening, and stretching deformation can easily occur during winding, seriously affecting the product quality. Therefore, a nonwoven fabric winding mechanism that can precisely adjust tension and is easy to operate is needed to meet market demands.

[0003] In the production of nonwoven fabrics, winding and traction is a necessary step when processing the raw material. However, existing winding equipment has certain shortcomings, making it difficult to accurately control the winding tension during the winding operation. When the winding tension is too high, it will cause the nonwoven fabric to stretch and deform; while when the tension is too low, it will cause the winding to become loose. These problems prevent the winding equipment from operating normally and stably, thus seriously reducing the overall winding efficiency.

[0004] Therefore, it is necessary to provide a nonwoven fabric winding mechanism with easily adjustable tension to solve the above-mentioned technical problems. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1 to 4 A tension-adjustable nonwoven fabric winding mechanism, comprising:

[0025] A base plate 1 is provided with several vertical plates 2. Feeding rollers 3 and winding rollers 5 are rotatably installed on the vertical plates 2 at both ends of the base plate 1. Tensioning rollers 4 are provided on the two vertical plates 2 in the middle of the base plate 1. A drive mechanism 9 is provided on the base plate 1 to drive the feeding rollers 3 and winding rollers 5 to rotate.

[0026] The tension adjustment mechanism 6 is set on the two vertical plates 2 located in the middle of the base plate 1 and at both ends of the tension roller 4;

[0027] The moving mechanism 7 is located on the lower surface of the base plate 1. Both ends of the moving mechanism 7 are provided with limiting mechanisms 8, which correspond to the feeding roller 3 and the winding roller 5, respectively.

[0028] refer to Figure 1 , Figure 2 As shown, two vertical plates 2 located in the middle of the base plate 1 are provided with movable grooves 10, and the tension roller 4 slides up and down along the inner wall of the movable groove 10.

[0029] refer to Figure 1 , Figure 2As shown, the tension adjustment mechanism 6 includes two support plates 601, each support plate 601 is fixedly installed on each vertical plate 2, and each support plate 601 is fixedly installed with an electric push rod 602. The output end of the electric push rod 602 is fixedly connected to a collar 603, and the two ends of the tension roller 4 are fixedly sleeved in the two collars 603.

[0030] In practice, the tension of the nonwoven fabric can be adjusted as needed during the winding process. The tension roller 4 moves up and down by controlling the extension and retraction of the electric push rod 602. When the electric push rod 602 retracts, the tension roller 4 moves down, increasing the tension of the nonwoven fabric; when the electric push rod 602 extends, the tension roller 4 moves up, decreasing the tension of the nonwoven fabric.

[0031] refer to Figure 1 , Figure 2 , Figure 3 As shown, the moving mechanism 7 includes three mounting frames 701, all of which are fixedly mounted on the lower surface of the base plate 1. A threaded rod 702 is rotatably mounted in the mounting frame 701 located in the middle of the base plate 1, and sliding rods 703 are fixedly connected in the mounting frames 701 located on both sides of the base plate 1. A threaded sleeve 704 is externally threaded to the threaded rod 702, and a moving plate 705 is fixedly mounted on the outer surface of the threaded sleeve 704. The two ends of the moving plate 705 slide on the inner walls of the two outer mounting frames 701 respectively. A first motor 706 is fixedly mounted on the mounting frame 701 located in the middle, and the output shaft of the first motor 706 is fixedly connected to one end of the threaded rod 702.

[0032] In practice, the first motor 706 is started to rotate the threaded rod 702, and the threaded sleeve 704, which is threadedly connected to the threaded rod 702, drives the moving plate 705 to move. During the movement, the sliding rod 703 ensures the stability of the moving plate 705.

[0033] refer to Figures 1-4 As shown, each limiting mechanism 8 includes a limiting plate 801. The two limiting plates 801 are fixedly installed at both ends of the moving plate 705, and both limiting plates 801 extend above the bottom plate 1. Each limiting plate 801 is fixedly installed with a bearing 802, and each bearing 802 is fixedly fitted with a limiting ring 803. One end of the feeding roller 3 and the winding roller 5 are inserted into the limiting ring 803.

[0034] In practice, as the movable plate 705 moves, the two limiting plates 801 on it move accordingly. At this time, the feeding roller 3 and the winding roller 5 are inserted into the limiting plates 801 through the limiting rings 803, and the limiting plates 801 also provide support for the feeding roller 3 and the winding roller 5. The distance between the vertical plate 2 and the limiting plates 801 is adjusted by moving the two limiting plates 801, thereby adapting to the winding requirements of nonwoven fabrics of different widths and improving the adaptability.

[0035] refer to Figures 1-4 As shown, the drive mechanism 9 includes two pulleys 901, which are fixedly connected to the other ends of the feeding roller 3 and the winding roller 5, respectively. The two pulleys 901 are connected by a belt 902. A second motor 903 is fixedly installed on one side of the vertical plate 2 by a bearing plate. The output shaft of the second motor 903 is fixedly connected to one of the pulleys 901.

[0036] In practice, the nonwoven fabric roll is installed on the feed roller 3, one end of which is passed under the tension roller 4 and then wound onto the take-up roller 5. Then, the second motor 903 is started to drive the pulley 901 connected to it to rotate. Through the transmission of the belt 902, the other pulley 901, the feed roller 3 and the take-up roller 5 rotate synchronously. At this time, the nonwoven fabric begins to be conveyed from the feed roller 3 to the take-up roller 5.

[0037] The working principle of the tension-adjustable nonwoven fabric winding mechanism provided by this utility model is as follows:

[0038] First, the nonwoven fabric roll is installed on the feed roller 3, one end of which is passed under the tension roller 4 and then wound onto the take-up roller 5. Next, the extension and retraction of the electric push rod 602 is controlled to move the tension roller 4 up and down. According to the tension of the nonwoven fabric, the tension roller 4 is adjusted to an appropriate height to meet the tension requirements of the nonwoven fabric, avoiding damage to the nonwoven fabric due to excessive tension and preventing the nonwoven fabric from falling off due to insufficient tension. Then, the first motor 706 is started to drive the threaded rod 702 to rotate, causing the two limit plates 801 to move with the moving plate 705 until the two limit plates 801 are aligned with the side of the nonwoven fabric, thus playing a limiting role. Finally, the second motor 903 is started to drive the pulley 901 connected to it to rotate, which synchronously drives the feed roller 3 and the take-up roller 5 to rotate through the transmission of the belt 902, thereby achieving the purpose of winding the nonwoven fabric.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
