Technical Field

[0001] The utility model relates to the technical field of needle felt processing, and specifically relates to an opening device for double-component fiber needle felt. Background Art

[0002] At present, the smallest ultrafine fiber in China is 0.89D, and the ultrafine fiber to achieve nano-level fineness depends on bicomponent fiber. Bicomponent fiber is a composite fiber formed by two polymers with different chemical structures or properties in a certain combination structure. The reason is that the production product has a fast transmission speed and a short process, and it is not possible to perform online dispersion processing on different components in the composite fiber.

[0003] If the bicomponent fibers are not dispersed during the production process, the two different polymer components in the bicomponent fibers will aggregate, resulting in an uneven structure of the bicomponent fibers, affecting the performance of the bicomponent fibers, and affecting the durability and strength of the bicomponent fibers. The unevenness of the bicomponent fibers will also lead to unstable quality of the textiles, and the filtering performance of fine dust particles will also be affected during use. Therefore, we propose a dispersion device for bicomponent fiber needle felt to ensure the stability of the fiber structure and quality. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] When the two-component fiber needle felt 3 is dispersed, the two-component fiber needle felt 3 is first placed in the box 1, and the two-component fiber needle felt 3 is clamped by the symmetrically arranged bent plates 4. Since the two sides of the bent plates 4 are arranged in an arc shape, the surface of the needle felt will not be scratched when it is placed. The vibration motors 5 on both sides provide the bending plates 4 with a vibration function, and then the two-component fiber needle felt 3 is symmetrically struck by the striking structure 6. The needle felt is dispersed by vibration and striking. After mechanical vibration, a certain proportion of different components in the composite fiber are separated from each other to form ultra-fine denier fibers with a finer diameter. The other side is transported by the symmetrical pressing rollers 2, which is convenient for subsequent processing of the two-component fiber needle felt 3.

[0017] The striking structure 6 includes a side plate 61, the side wall of the side plate 61 is fixedly connected to the side wall of the curved plate 4, the two ends of the side plate 61 are fixedly connected to the inner wall of the box body 1, the inner cavity of the side plate 61 is sleeved with a concave plate 62, the lower surface of the concave plate 62 is fixedly connected to a striking plate 63, the side wall of the striking plate 63 is gap-matched with the side wall of the two-component fiber needle-punched felt 3, the striking plate 63 is fixedly connected to the side plate 61 with a compression spring 64, the inner side wall of the concave plate 62 is fixedly connected to a rack 65, the side wall of the rack 65 is meshed with a semi-toothed roller 66, and the two sides of the semi-toothed roller 66 are connected to the box body 1 Next, when the striking work is performed, the semi-toothed rollers 66 on both sides are started, and the semi-toothed rollers 66 will rotate. A latching tooth is provided on one side of the semi-toothed rollers 66. When the semi-toothed rollers 66 are rotated to a certain position, the latching teeth of the semi-toothed rollers 66 will mesh with the rack 65 of the concave plate 62. After the semi-toothed rollers 66 are meshed with the rack 65, the semi-toothed rollers 66 are rotated to pull the concave plate 62 outward. When the semi-toothed rollers 66 are rotated to the other side where there is no latching tooth, the semi-toothed rollers 66 are disengaged from the rack 65, and the compression springs 64 are used to reset and push, and the striking plate 63 will strike the surface of the two-component fiber needle-punched felt 3.
