Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, and in particular to a spunlace nonwoven fabric water needle plate structure. Background Technology

[0002] Spunlace nonwoven fabric is a type of nonwoven fabric that uses high-pressure water jets to weave fibers into a cloth. It is widely used in fields such as wet wipes, hygiene products, medical supplies, and filter materials. Spunlace nonwoven needle plates are devices used in the spunlace process to pass water through the fiber layer. They are plate-like structures composed of multiple needles. The impact force of the high-pressure water jets interweaves the fibers together to form a mesh structure of nonwoven fabric.

[0003] Chinese patent discloses a stabilizing water needle plate for spunlace nonwoven fabric production (authorization announcement number CN214938266U). The patented technology includes a plate, a guide positioning block, a protective groove, micro water spray needle holes, a corrosion-resistant coating, a guide positioning inclined surface, a fixing block, and a push-pull block. This utility model achieves the effect of reducing the wear of the water needle plate by high-pressure water flow, greatly improving the service life of the water needle plate, while reducing the possibility of water needle plate slippage, increasing the stability of the water needle plate, and enabling the water needle plate to output water stably.

[0004] However, most existing spunlace nonwoven fabric needle plate structures are fixedly installed, which necessitates complete replacement when the needle plate is damaged, increasing costs. For example, the aforementioned prior art uses a fixed installation method. Therefore, those skilled in the art provide a spunlace nonwoven fabric needle plate structure to solve the problems mentioned in the background section. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a spunlace nonwoven fabric needle plate structure, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a spunlace nonwoven fabric needle plate structure, comprising a sheet material, a connecting plate installed at the end face of the upper surface of the sheet material, a guide positioning block connected to the upper surface of the connecting plate, and an adsorption magnetic block provided inside the guide positioning block;

[0007] The upper surface of the sheet metal is provided with a protective groove, and a needle plate is installed inside the protective groove. The upper surface of the needle plate is provided with water needle holes. Screws are symmetrically arranged on both sides of the sheet metal. A movable groove is provided inside the protective groove. One end of the screw is provided with a movable plate inside the protective groove, and a positioning rod is provided through the outer side of the movable plate.

[0008] As a further technical solution of this utility model, the guide positioning block and the connecting plate are arranged in an "L" shape, and the adsorption magnetic block is arranged in the middle position inside the guide positioning block.

[0009] As a further technical solution of this utility model, limit holes are provided on both sides of the needle plate, and one end of the positioning rod is embedded in the limit hole.

[0010] As a further technical solution of this utility model, a guide hole is provided on the inner side of the moving groove, and the other end of the positioning rod slides inside the guide hole.

[0011] As a further technical solution of this utility model, a bearing is installed on one side of the movable plate, and one end of the screw is embedded inside the bearing.

[0012] As a further technical solution of this utility model, the plate material has a screw hole inside, and the screw is threadedly connected to the screw hole.

[0013] This utility model provides a spunlace nonwoven fabric needle plate structure, which has the following advantages compared with the prior art:

[0014] 1. This design provides a spunlace nonwoven fabric needle plate structure. The rotation of the screw causes the moving plate to move inside the moving groove. During the movement, a positioning rod that penetrates the outside of the moving plate moves towards the needle plate and embeds into the limiting hole. This allows the needle plate to be installed inside the protective groove, achieving the purpose of installing the needle plate. This structure is simple and allows for quick installation and disassembly of the needle plate, facilitating its replacement for spunlace nonwoven fabric processing operations and reducing costs.

[0015] 2. The spunlace nonwoven fabric needle plate structure designed in this paper, through the setting of guide positioning blocks, adsorption magnetic blocks and connecting plates, allows the plate to be quickly slidably installed on the mounting surface of the spunlace head using the connecting plate and guide positioning blocks, and improves its installation stability by using adsorption magnetic blocks, which can be strong magnetic blocks or electromagnetic blocks, thus making the stability better.

A positioning rod 44 is provided through the outer side of the moving plate 41.

[0027] like Figure 2 As shown, the guide positioning block 2 and the connecting plate 22 are arranged in an "L" shape. The magnetic adsorption block 21 is located in the middle of the guide positioning block 2. This arrangement allows the plate 1 to be installed below the water jet head using the guide positioning block 2 and the connecting plate 22. The magnetic adsorption block 21 of the strong magnetic block or electromagnetic block can be used to install the plate 1 with the water jet head, thus achieving the purpose of quick installation and disassembly of the plate 1.

[0028] like Figure 3 As shown, limit holes are provided on both sides of the needle plate 3. One end of the positioning rod 44 is embedded in the limit hole.
