Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a leveling device for nonwoven fabrics. Background Technology

[0002] In the production and processing of nonwoven fabrics, leveling devices play a crucial role. After manufacturing, nonwoven fabrics often have a certain degree of unevenness on their surface, which affects subsequent processing steps and the quality of the final product. To improve the surface smoothness of nonwoven fabrics, nonwoven fabric leveling devices have emerged. These devices mostly use the traction action of take-up rollers and steam rollers to achieve the leveling process of nonwoven fabrics. The working principle is that the take-up roller rotates continuously, providing forward power for the nonwoven fabric to pass smoothly through the steam roller. High-temperature steam is introduced into the steam roller, and the heat of the steam softens the nonwoven fabric fibers. Under the combined action of traction force, the nonwoven fabric is stretched and leveled, thereby achieving the purpose of improving surface smoothness. This leveling method based on the coordinated work of steam rollers and take-up rollers is currently a common technical means in the nonwoven fabric industry.

[0003] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art:

[0004] To ensure the ideal flatness of nonwoven fabrics, current nonwoven fabric leveling devices typically require a large radial dimension of the steam roller. This is because a larger radial dimension increases the contact area between the steam roller and the nonwoven fabric, allowing the steam to act more evenly on the nonwoven fabric, thereby more effectively softening the fibers and leveling them. However, this design also leads to a significant increase in the floor space occupied by the entire leveling device. In modern production workshops, large-footprint devices not only increase the construction cost of the production site but also limit the flexibility of the production line layout and reduce the utilization rate of production space. At the same time, large-sized steam rollers also face many difficulties in manufacturing, installation, and maintenance, increasing production costs and operational complexity.

[0005] Therefore, the aforementioned technical problems need to be solved. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, this utility model proposes a nonwoven fabric leveling device, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0008] A nonwoven fabric leveling device includes a flattening mechanism located in front of a winding machine for conveying the nonwoven fabric in a serpentine path. The flattening mechanism is composed of several stacked unit modules, and any two adjacent unit modules are fixedly connected by a first bolt.

[0009] The unit module includes a frame and a steam plate fixed to the frame by a second bolt. The front and rear sides of the steam plate are provided with clamping rollers for guiding and conveying nonwoven fabric.

[0010] Preferably, the steam plate includes a liner and a serpentine steam channel formed inside it, as well as an upper cover plate and a lower cover plate respectively covering and encapsulating the top and bottom of the liner. Both sides of the upper cover plate have flanges for second bolt assembly, and both sides of the lower cover plate have connection ports for connecting external pipelines. The steam plate is a key component for achieving non-woven fabric leveling. The external pipeline introduces high-temperature steam into the steam channel through a connection port. Preferably, the steam channel is configured with a serpentine structure, which helps to ensure uniform distribution of high-temperature steam within the steam plate.

[0011] Preferably, the device further includes two symmetrically distributed channels located on the inner sides of the two flanges and connected to the outside. Each channel has a baffle slidably inserted into its inner side, and each channel has a locking screw threaded vertically through its top for positioning the baffle. By adjusting the position of the baffle within the channel and using the locking screw for positioning, the device can accommodate the leveling of nonwoven fabrics of different widths.

[0012] Preferably, the frame consists of two symmetrically distributed side plates and two connecting beams vertically welded to the bottom between the two side plates. The frame provides stable support for the entire unit module.

[0013] Preferably, the lower part of the side plate has strip-shaped holes distributed along its length, and an operation window is provided above the strip-shaped holes. The strip-shaped holes provide structural support for the connection of external pipelines, while the operation window facilitates operation of the device's interior by staff, such as guiding the insertion and installation of non-woven fabric.

[0014] The beneficial effects of this utility model are:

[0015] The technical solution of this utility model, by setting up a flattening mechanism composed of several stacked unit modules, allows the nonwoven fabric to be transported in a serpentine path, effectively utilizing space, reducing the overall footprint of the device, and lowering the construction cost of the production site. At the same time, by replacing the traditional steam roller with a steam plate, it ensures uniform distribution of steam and heat transfer, guaranteeing the softening effect of the nonwoven fabric fibers, and making production and maintenance more convenient. In addition, the modular design allows for flexible adjustment of the production line layout to achieve flexible control of the flattening effect. Attached Figure Description

[0029] Based on the above structure, the nonwoven fabric leveling device consists of a flattening mechanism 100, which is composed of several stacked unit modules 110, so that the nonwoven fabric can be conveyed in a serpentine path within the flattening mechanism 100. At the same time, the nonwoven fabric is flattened. Specifically, when the nonwoven fabric passes through the steam plate 1130 during the serpentine path conveying process, heat is transferred to the nonwoven fabric, causing the nonwoven fabric fibers to soften. Meanwhile, the front and rear sides of the steam plate 1130 are equipped with clamping roller groups 1140 for guiding and conveying the nonwoven fabric. The clamping roller groups 1140 guide and clamp the nonwoven fabric, ensuring that the nonwoven fabric can pass through the steam plate 1130 stably. The nonwoven fabric leveling device is equipped with a flattening mechanism 100 composed of several unit modules 110 stacked together, which allows the nonwoven fabric to be conveyed in a serpentine path, effectively utilizing space, reducing the overall footprint of the device, and reducing the construction cost of the production site. At the same time, replacing the traditional steam rollers with the steam plate 1130 ensures the uniform distribution of steam and heat transfer, ensuring the softening effect of the nonwoven fabric fibers, and making production and maintenance more convenient. In addition, the modular design allows for flexible adjustment of the production line layout to achieve flexible control of the leveling effect.

[0030] Furthermore, the steam plate 1130 includes a liner 1131 and a steam channel 1132 formed inside it in a serpentine structure, as well as an upper cover plate 1133 and a lower cover plate 1134 respectively covering and encapsulating the top and bottom of the liner 1131. Both sides of the upper cover plate 1133 are provided with flanges 1135 for assembly of the second bolt 1120, and both sides of the lower cover plate 1134 are provided with connection ports 1136 for docking with external pipelines.

[0031] Furthermore, it also includes two symmetrically distributed channels 1137 located on the inner side of the two flanges 1135 and connected to the outside. Each channel 1137 has a baffle 1138 slidably inserted inside it, and each channel 1137 has a locking screw 1139 threaded vertically through its top for positioning the baffle 1138.

[0032] Furthermore, the frame 1110 consists of two symmetrically distributed side plates 1111 and two connecting beams 1112 vertically welded to the bottom between the two side plates 1111.

[0033] Furthermore, the lower part of the side plate 1111 is provided with strip-shaped holes 1113 distributed along its length, and an operation window 1114 is provided above the strip-shaped holes 1113.
