Description

Technical Field

[0001] This invention relates to the field of spinning composite board technology, and in particular to a spinning composite board and its spunbond bicomponent spinning assembly. Background Technology

[0002] Hygiene products have become commonplace in people's lives. Non-woven fabrics are used in hygiene products to improve their softness. Non-woven fabric production is carried out using spinning components. These components adopt a core-sheath composite structure. In the spinning component, a composite plate gathers one material from multiple sets of channels to the center, while another material passes through the center. The two form a cylindrical material with a core-sheath structure. In the existing composite plate, when one material gathers, the material flows directly to the center. As more and more material accumulates, the adjacent materials will merge, resulting in poor fusion between the materials in the multiple channels and a lack of adhesion between the materials. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: in order to solve the problem that when one of the materials in the existing composite board converges, the material flows directly to the middle, and the materials between adjacent materials only merge as more and more materials are added, resulting in poor fusion between the materials in multiple material channels and no adhesion between the materials, a spinning composite board and a spunbond bicomponent spinning assembly are provided.

[0004] The technical solution adopted by this invention to solve its technical problem is: a spinning composite board, comprising a board body, on which a fusion groove corresponding to multiple material channels is formed. A composite hole is formed within the fusion groove, and the multiple material channels are arranged around the composite hole. An island is provided within the fusion groove, and the island is used to guide a portion of the material in the corresponding material channel towards another material channel, and to fuse the material between adjacent material channels. Compared with the prior art, this solution, by setting islands within the fusion groove, allows a portion of the material in two adjacent material channels to converge and fuse, improving the fusion properties and adhesion between the materials, and ultimately improving the physical properties of the product.

[0005] To improve the material cohesion between adjacent material channels, some implementation methods are adopted in which the islands are arranged in a one-to-one correspondence with the material channels. This one-to-one correspondence between islands and material channels ensures that material in each channel can be diverted, thereby improving the material cohesion between adjacent material channels.

[0006] To achieve the fusion tank, in some preferred embodiments, the fusion tank is formed by an intermediate fusion zone and a confluence zone that is arranged around and interconnected with the fusion zone, wherein there are at least two confluence zones. The fusion tank is configured as two zones, one zone being the fusion zone and the other zone being the confluence zone. The fusion zone is used to combine two different materials to form a core-skin structure, and the confluence zone is used to correspond to the flow channel and to converge the material from the flow channel to the fusion zone.

[0007] To facilitate the merging of materials from two adjacent feed channels, in some preferred embodiments, the island is positioned within the confluence zone, and the composite hole is positioned within the fusion zone. By positioning the island in the confluence zone and the composite hole in the fusion zone, the material in one feed channel is guided through the island and merged with the material guided through the island in the other feed channel.

[0008] To facilitate the fusion of materials from adjacent feed channels, in some preferred embodiments, the cross-sectional area of ​​the confluence zone gradually increases from the outside to the inside of the fusion groove. By setting the cross-sectional area of ​​the confluence zone to gradually increase from the outside to the inside of the fusion groove, similar to a trumpet-shaped structure, it serves two purposes: firstly, it allows one material to better diffuse and coat the other material, thus forming a core-skin structure; secondly, it improves the fusion between materials from adjacent feed channels, ensuring adhesion between the materials.

[0009] To facilitate better material convergence during fusion between adjacent feed channels, in some preferred embodiments, a rounded transition surface is provided between adjacent feed channels. This rounded transition surface guides the material and facilitates better material convergence during fusion.

[0010] In some preferred embodiments, the island is elliptical.

[0011] To better facilitate material flow through the island, in some preferred embodiments, the major axis of the island is positioned along the flow direction of the material within the confluence area. The island is elliptical in shape, and its major axis is aligned with the material flow direction. This guides the material as it passes through the island, causing some material to flow outwards while the rest flows inwards towards the center, thus improving the island's ability to direct material flow.

[0012] To facilitate the installation of the composite panel, in some preferred embodiments, mounting holes are provided on the composite panel.

[0013] This embodiment is an application of a spinning composite plate, specifically: a spunbond bicomponent spinning assembly, which is equipped with the spinning composite plate as described above.

[0014] The beneficial effects of the present invention are as follows: When the spinning composite board and its spunbond bicomponent spinning assembly of the present invention are used, by setting islands in the fusion tank, the islands will gather and fuse a portion of the material in two adjacent material channels, thereby improving the fusion and adhesion between the materials and improving the physical properties of the product. This avoids the problem in the existing composite board where, when one type of material gathers, the material flows directly to the middle, and the materials between adjacent materials only fuse as more and more material accumulates, resulting in poor fusion between the materials in multiple material channels and a lack of adhesion between the materials.

[0024] Example 1

[0025] like Figure 1-3 As shown, a spinning composite board includes a board body 1, on which a composite zone is provided. Fusion grooves 2 are arrayed within the composite zone, each fusion groove 2 corresponding to multiple material channels. A composite hole 3 is opened within the fusion groove 2, used to allow two materials to pass through and fuse into a core-sheath structure. Multiple material channels are arranged around the composite hole 3. An island 4 is provided within the fusion groove 2, corresponding one-to-one with each material channel. The island 4 is used to guide a portion of the material in its corresponding channel towards another channel and to fuse the materials between adjacent material channels.

[0026] The fusion tank 2 is formed by the intermediate fusion zone 5 and the confluence zones 6 that are arranged around the fusion zone 5 and interconnected with each other. In this embodiment, there are four confluence zones 6 that are evenly distributed along the circumference. The confluence zones 6 include, but are not limited to, four, two, three, five or more. It can also be said that there are four material channels. At the same time, the islands 4 correspond one-to-one with the confluence zones 6 in this embodiment, and there are also four islands 4.

[0027] An island 4 is located within the confluence zone 6. The island 4 is elliptical, and its major axis is aligned with the flow direction of the material within the confluence zone 6. A composite hole 3 is located within the fusion zone 5. The cross-sectional area of ​​the confluence zone 6 gradually increases from the outside to the inside of the fusion tank 2. An arc transition surface 7 is provided between adjacent confluence zones 6.

[0028] The composite board has mounting holes. External screws or limiting posts pass through the mounting holes to install and fix the composite board, distribution plate, and spinneret.

[0029] Example 2

[0030] Example 2 is an application of Example 1, specifically: a spunbond bicomponent spinning assembly, which is equipped with the above-mentioned spinning composite plate.

[0031] When the above-mentioned spinning composite board and its spunbond bicomponent spinning assembly are in use, the material in the four feed channels enters the confluence zone 6 in the fusion tank 2. The island 4 in each confluence zone 6 guides the material, directing a portion of the material to another confluence zone 6, and causing the materials in the two confluence zones 6 to adhere to each other and fuse together. The other portion of the material converges in the middle and flows to the composite hole 3 in the fusion zone 5. Another material passes through the composite hole 3, so that the converged material covers the other material and forms a core-skin structure.

[0032] The above description, based on the preferred embodiments of the present invention, provides inspiration. Those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification but must be determined according to the claims.
