Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric technology, specifically to a component for the production of ultra-low basis weight leather base fabric. Background Technology

[0002] Ultra-low weight leather base fabric is a lightweight leather material commonly used in the manufacture of various soft bags, footwear, clothing, and accessories. This type of base fabric typically has a very low weight, such as below 100 g / m², or even lighter. Due to its low weight, finished products are lighter in use, making it suitable for applications requiring reduced weight. Ultra-low weight leather base fabric often has good softness and comfort, making it suitable for products worn close to the skin. Some ultra-low weight leather base fabrics may also have good breathability, making them particularly popular in footwear and clothing. With increasing environmental awareness, some ultra-low weight leather base fabrics may be made from renewable or environmentally friendly materials, aligning with the trend of sustainable development. This type of base fabric can be used in a variety of applications, not limited to traditional leather products, and can be combined with various types of materials.

[0003] The spinnerets in existing spinning components for producing leather base fabrics generally have circular holes with relatively large diameters. This makes it impossible to effectively reduce the basis weight of leather base fabrics by improving the thickness and shape of the filament bundles, thereby reducing the efficiency and quality of ultra-low basis weight leather base fabric production and increasing production costs. To address this, we propose a component for the production of ultra-low basis weight leather base fabrics. Utility Model Content

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figures 1-5 As shown in this embodiment, a component for producing ultra-low basis weight leather base fabric includes a housing 1. A pressure head structure and a sand cup structure are provided on the inner side of the housing 1. The pressure head structure is located above the sand cup structure. A component connecting seat 3 is provided on the top of the pressure head structure. A melt pipe 13 is opened on the top of the component connecting seat 3. One end of the melt pipe 13 passes through the pressure head structure and communicates with the sand cup structure. A spinneret 14 is provided below the sand cup structure and between the inner walls of the housing 1. A triangular hole 17 is opened inside the spinneret 14. A cylindrical pin 15 is slidably connected to the outer side of the housing 1. One end of the cylindrical pin 15 passes through the housing 1 and abuts against the spinneret 14. A screw 2 is threadedly connected to the side of the component connecting seat 3 near the housing 1. One end of the screw 2 extends to the top of the component connecting seat 3. A gasket 16 is provided on the outer side of the melt pipe 13 and at the top of the component connecting seat 3.

[0023] In the production of ultra-low basis weight leather base fabric, the input end of the externally designed metering pump is first extended through the gasket 16 into the interior of the melt pipe 13. The gasket 16 ensures the sealing of this connection process. Then, the externally designed metering pump is used to introduce the molten raw material into the melt pipe 13. The molten material passes through the pressure head structure and enters the sand cup structure along the melt pipe 13. After being filtered by the sand cup structure, it comes into contact with the spinneret 14. Finally, it is formed and flows out through the triangular holes 17 opened inside the spinneret 14. In this way, by changing the pressure bearing capacity of the components and the shape of the spinneret holes, the fineness of the filament bundle is reduced, the shape of the filament bundle is changed, the cohesion between the filament bundles after web formation is improved, and the effect of reducing the basis weight per unit area of ​​the base fabric is achieved, thus producing ultra-low basis weight leather base fabric.

[0024] like Figures 1-5 As shown, the pressure head structure includes an upper cover 4, which is disposed between the inner walls of the housing 1. An aluminum nozzle 5 is disposed between the upper cover 4 and the housing 1. A tightening ring 6 is disposed on the outside of the melt pipe 13 and between the inner walls of the upper cover 4.

[0025] The upper cover 4, located between the upper cover and the inner wall of the housing 1, helps to form a closed container, preventing the melt from leaking during processing and ensuring a clean and safe production environment. An aluminum nozzle 5 is provided between the upper cover and the housing 1, which takes advantage of the corrosion resistance of aluminum and helps to improve the durability of the entire component in long-term use. Finally, a tight ring 6 is provided on the outside of the melt pipe 13, which helps to improve the sealing of the system and prevent melt leakage or external contaminants from entering the pipe.

[0026] like Figures 1-5 As shown, the sand cup structure includes a sand cup body 11, with a perforation 18 inside the sand cup body 11. A first three-layer filter screen 7 is provided between the sand cup body 11 and the upper cover 4. A liner ring 9 and a second three-layer filter screen 10 are provided above the perforation 18 and inside the sand cup body 11. A ninth-layer filter screen 12 is provided between the sand cup body 11 and the spinneret 14. Filter sand 8 is provided inside the sand cup body 11 and between the first three-layer filter screen 7 and the second three-layer filter screen 10.

[0027] The falling melt, after passing through the melt pipe 13, comes into contact with the first three-layer filter screen 7. After being filtered once by the first three-layer filter screen 7, it enters the interior of the sand cup body 11 and comes into contact with the filter sand 8. After being deeply filtered by the filter sand 8, it finally passes through the second three-layer filter screen 10 and comes into contact with the ninth-layer filter screen 12 along the drain hole 18. After being filtered by the ninth-layer filter screen 12, it enters the spinneret 14. Thus, the melt is filtered in multiple stages through the sand cup structure, which can effectively improve the physical properties of the fiber and ultimately produce a higher quality and better performance ultra-low weight leather base fabric.

[0028] like Figures 1-5 As shown, the filter sand 8 is composed of coarse sea sand 19 and fine sea sand 20, with the coarse sea sand 19 placed on top of the fine sea sand 20.

[0029] The upper layer of coarse sea sand (approximately 20 mesh) acts as a preliminary filter for the melt, while the lower layer of fine sea sand (approximately 30 mesh) acts as a fine filter for the melt.

[0030] This utility model provides a component for the production of ultra-low basis weight leather base fabric. The specific working principle is as follows: In the production process of ultra-low basis weight leather base fabric, the input end of the externally designed metering pump is first extended through the gasket 16 into the interior of the melt pipe 13. The gasket 16 is used to ensure the sealing of this connection process. Then, the externally designed metering pump is used to introduce the melt raw material into the melt pipe 13. The melt flows along the melt pipe 13, passes through the tight ring 6, and comes into contact with the first three-layer filter screen 7. After the initial filtration by the first three-layer filter screen 7, the melt enters the interior of the sand cup 11 and is deeply filtered with the filter sand 8. Subsequently, after the melt is filtered again by the second three-layer filter screen 10, it comes into contact with the ninth-layer filter screen 12 through the drain hole 18. Finally, the melt raw material passes through the ninth-layer filter screen 12, contacts the spinneret 14, and flows out through the triangular hole 17.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
