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

[0021] Example 1, please refer to Figure 1-Figure 5 , This embodiment is a non-woven composite device.

[0022] 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).

[0023] 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).

[0024] The rotating speed (line speed) of the first upper pressure roller 41, the first lower pressure roller 42, the second upper pres...

Embodiment 2

[0035] Embodiment 2, this embodiment is a non-woven composite device.

[0036] see figure 1 , The difference between this embodiment and embodiment one is that it also includes the fast roller 5 arranged at the rear of the last group of squeeze rollers 4 (the rear according to the moving direction of the nonwoven layer 3); the fast roller 5 comprises upper fast roller 51 and lower fast roller 52 that are arranged up and down; Upper fast roller 51 and lower fast roller 52 are all covered with friction sleeve 53; 1.05 times or more of the rotational speed (linear velocity) of the pressing roller 4.

[0037] The working principle of the non-woven fabric composite device in this embodiment is: the surface cloth layer 1, the hot melt adhesive layer 2 and the non-woven fabric layer 3 output from the last group of squeeze rollers 4, pass through the squeeze rollers 4 Afterwards, the hot melt glue is evenly distributed and the whole is wavy; when passing through the gap between the ...

Abstract

The invention relates to the field of non-woven production equipment, in particular to a non-woven compounding device. The non-woven compounding device comprises an extrusion press roller, wherein the extrusion press roller comprises a first upper press roller and a first lower press roller which are arranged up and down, as well as a second upper press roller and a second lower press roller which are arranged up and down; the first upper press roller is arranged in front of the second lower press roller; crescent bulges are fixed on the first upper press roller and the second upper press roller; the first upper press roller, the first lower press roller, the second upper press roller and the second lower press roller have the same rotating speed and have the same radius R; the distance between the axis of the first upper press roller and the axis of the second upper press roller is a distance A; the angle corresponding to the bulges is a bulge opposite angle B; the mutually staggered angle of the first upper press roller and the second upper press roller is a staggered angle C; the A, the B and the C meet A=(B / 360)*N*2*Pi*R and C=N / 2*B, or meet A= (B / 360)*N*2*Pi*R+(B / 2*360)*2*Pi*R and C=N*B. The non-woven compounding device enables hot melt adhesive to be distributed uniformly so as to guarantee the compounding strength between a surface cloth layer and a non-woven layer.

Description

technical field [0001] The invention relates to the field of non-woven fabric production equipment, in particular to a non-woven fabric composite 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 practice is to ap...
