A preparation device for non-woven fabric with convex lines on the surface

Abstract

The invention discloses a device for preparing non-woven fabrics with convex stripes on the surface, which comprises a fiber mixing assembly and a forming tray, wherein the fiber mixing assembly comprises a water tank and a plurality of first liquid guide pipes; a water body uniformly mixed with short fibers is filled in the water tank; the water body is introduced into the forming tray through the first liquid guide pipes; the forming tray is provided with a plurality of regular and / or irregular strip-shaped grooves at intervals; the grooves are provided with a plurality of first opening holes; the non-grooves of the forming tray are provided with a plurality of second opening holes; the apertures of the first opening holes and the second opening holes are smaller than the length of the short fibers; a blocking hole plate is arranged below the forming tray; the diameter and the arrangement of the hole plugs on the blocking hole plate are arranged relative to the second opening holes.According to the device, the short fibers can be uniformly dispersed in the water body, and the water body mixed with the short fibers is introduced into the forming tray with the opening holes; the diameter of the first opening holes and the diameter of the second opening holes are smaller than the length of the short fibers, so that the short fibers are deposited on the forming tray to form thenon-woven fabrics with the three-dimensional convex stripe paths, and the device has the advantages that the structure is simple.

Description

technical field [0001] The invention relates to the field of preparation of non-woven fabrics, in particular to a preparation device for non-woven fabrics with convex lines on the surface. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or randomly arranged fibers. Compared with traditional non-woven fabrics, the manufacturing process is simple. The preparation process of non-woven fabrics mainly includes the steps of web formation and reinforcement. Specifically, the raw materials are firstly sent to the carding mechanism after being loosened. On the curtain, after laying 5-20 layers on the net curtain, a fiber net is formed, and finally it is reinforced by a reinforcement mechanism to form a non-woven fabric. However, as the demand for non-woven products gradually increases, people cannot be satisfied with traditional non-woven fabrics, and begin to need more functional non-woven fabrics. Non-woven fabrics with th...

Problems solved by technology

However, as the demand for non-woven products gradually increases, people cannot be satisfied with traditional non-woven fabrics, and begin to need more functional non-woven fabrics. Non-woven fabrics with three-dimensional touch are one of them, but When preparing this type of non-woven fabric, the formation of the fiber web and whether it is evenly arranged are technical difficulties.
