Problems solved by technology

[0005] The hot melt adhesive coated between the non-woven fabric and the surface fabric may be unevenly coated due to various reasons, such as unstable voltage, annoyed coating equipment, etc.
Uneven application of hot melt adhesive will lead to low composite strength between non-woven fabric and surface fabric, which will affect product quality

Embodiment 1

[0020] Example 1, please refer to Figure 1-Figure 5 , This embodiment is a non-woven composite device.

[0021] Please refer to the accompanying drawings, the present invention is a non-woven composite device, which includes a squeeze roller 4; the squeeze roller 4 includes a first upper roller 41 arranged up and down and a first lower roller 42, a second roller arranged up and down. The upper pressing roller 43 and the second lower pressing roller 44; the first upper pressing roller 41 is arranged in front of the second lower pressing roller 44 (in front of the moving direction of the nonwoven fabric layer 3).

[0022] Both the first upper pressing roller 41 and the second upper pressing roller 43 are fixedly provided with crescent-shaped protrusions 45 (that is, the shape formed by the intersection of two circles with different centers).

[0023] The rotating speed (line speed) of the first upper pressure roller 41, the first lower pressure roller 42, the second upper pres...

Embodiment 2

[0034] Embodiment 2, this embodiment is a composite leveling device for non-woven fabrics.

[0035] see figure 1 , the difference between this embodiment and embodiment one is that it also includes the fast roller 5 arranged on the rear of the second upper pressing roller 43 (the rear according to the moving direction of the nonwoven layer 3); The upper quick roller 51 and the lower quick roller 52; the upper quick roller 51 and the lower quick roller 52 are all covered with friction sleeves 53; 1.05 times or more of the rotational speed (linear velocity) of the roller 43 .

[0036] The working principle of the non-woven composite flattening device of this embodiment is: the surface cloth layer 1, the hot melt adhesive layer 2 and the non-woven fabric layer 3 output from between the second upper pressure roller 43 and the second lower pressure roller 44, After passing through the pressing roller 4, the hot-melt glue is evenly distributed and has a wavy shape as a whole; when...

Abstract

The invention relates to the field of non-woven production equipment, in particular to a non-woven composite flattening device. The device comprises an extrusion press roller; the extrusion press roller comprises a first upper press roller and a first lower press roller which are arranged up and down, and a second upper press roller and a second lower press roller that are arranged up and down; the first upper press roller is arranged in front of the second lower press roller; the non-woven composite flattening device is characterized by further comprising a rapid roller wheels arranged behind the second upper press roller; the rapid roller wheel comprises an upper rapid roller wheel and a lower rapid roller wheel which are arranged up and down; two friction sleeves respectively sleeve the upper rapid roller wheel and the lower rapid roller wheel; the rotating speeds of the upper rapid roller wheel and the lower rapid roller wheel are equal to each other and are 1.05 times higher than that of the second upper press roller. The non-woven composite flattening device is capable of flattening a surface cloth layer, a hot melt adhesive layer and a non-woven layer by pulling, and prevents the surface cloth layer and the non-woven layer from being broken by pulling.

Description

technical field [0001] The invention relates to the field of non-woven fabric production equipment, in particular to a non-woven fabric composite flattening device. Background technique [0002] Non-woven fabrics are also called non-woven fabrics, and their manufacturing process is different from the traditional textile process. The biggest feature of non-woven fabrics is that no spinning is required, and the manufacturing process is similar to the papermaking process. [0003] At present, the fibers are usually directly and continuously processed into non-woven fabrics on a production line; in the non-woven fabric production line, the oriented or randomly arranged fibers are combined by friction, cohesion, bonding, etc. The needle punching unit repeatedly punctures the fibers in the direction perpendicular to the surface of the non-woven fabric to form a non-woven fabric. [0004] The produced non-woven fabric is usually compounded with the surface cloth; the usual practi...
