Description

Technical Field

[0001] The invention belongs to the technical field of non-woven fabric processing, and in particular relates to a non-woven fabric composite device and a composite method. Background Art

[0002] Non-woven fabrics are also called nonwoven fabrics. Their manufacturing process is different from the traditional textile process. The biggest feature of non-woven fabrics is that they do not require spinning, and the manufacturing process is similar to the papermaking process. At present, fibers are usually processed into non-woven fabrics directly and continuously on a production line; in the non-woven fabric production line, oriented or randomly arranged fibers are combined by friction, cohesion, bonding and other methods, and repeatedly punctured by a needle punching machine or a needle punching unit in the direction perpendicular to the non-woven fabric surface to form a non-woven fabric. The produced non-woven fabric is usually compounded with the surface fabric; the usual practice is to apply hot melt adhesive between the non-woven fabric and the surface fabric to bond the non-woven fabric and the surface fabric together. The hot melt adhesive applied between the non-woven fabric and the surface fabric may be unevenly applied due to various reasons. Uneven hot melt adhesive coating will result in low composite strength between the non-woven fabric and the surface fabric, affecting product quality.

[0003] The existing Chinese patent document with publication number CN106346939B proposes a non-woven fabric composite device, in which the distance between the axis center of the first upper pressing roller and the axis center of the second upper pressing roller is distance A, the angle subtended by the protrusion is protrusion diagonal B, and the angle between the first upper pressing roller and the second upper pressing roller is staggered as staggered angle C to uniformly extrude the non-woven fabric and the hot melt adhesive to solve the above problems. However, for different non-woven fabric materials, thicknesses and characteristics of hot melt adhesives, it is necessary to frequently adjust the distance parameters between the first upper pressing roller and the second upper pressing roller to achieve the best composite effect. The adjustment process may be time-consuming and troublesome, affecting production efficiency.

[0004] Therefore, the present invention proposes a non-woven fabric composite device and a composite method to solve the problem that the non-woven fabric composite device in the prior art cannot easily adjust the distance parameters between the first upper pressing roller and the second upper pressing roller according to different non-woven fabric materials, thicknesses and characteristics of hot melt adhesives. A deformable roller is used in conjunction with a glue coating roller to integrate the glue coating and pressing of the non-woven fabric material, thereby improving the production efficiency of the non-woven fabric.

The inner walls of the two sets of limited fixed disks 212 are both rotatably installed with driving gears 215, and the outer surfaces of the two sets of driving gears 215 are respectively meshed with the outer surfaces of the two sets of adjusting toothed disks 214, and an adjusting toothed disk 214 is fixedly installed between the rotating shafts of the two sets of driving gears 215. The rod 213, the inner walls of the extrusion composite roller 21 and the limit fixing disk 212 are all provided with a rotating hole adapted to the adjusting rod 213, and the outer surface of one end of the extrusion composite roller 21 is provided with a locking disk adapted to the adjusting rod 213, and the position of the locking disk of the adjusting rod 213 corresponds to the position of the operating port 112, and the sliding rod 2111 is slidably installed on the side surface of the limit fixing disk 212 close to the adjusting toothed disk 214, and one end of the sliding rod 2111 is fixedly installed with a sliding cylinder adapted to the adjusting groove 2141;

[0038] In this embodiment, the conveyor belt 12 installed above the base 1 serves to transport non-woven fabrics, the material guide assembly 13 serves to introduce the upper layer of non-woven fabrics, the device frame 11 serves to install the extrusion composite roller assembly 2 and the uniform glue coating roller assembly 3, the observation window 111 can observe the pressing distance between the extrusion composite roller 21 and the conveyor belt 12, and the operation port 112 is convenient for operating the rotating adjustment rod 213.

Embodiment 2

[0039] See also Figures 1 to 12 On the basis of the first embodiment, in order to make the extrusion composite roller 21 have a better pressing and composite effect on the non-woven fabric layers, the present embodiment further proposes that a main extrusion pad 2112 is arranged in the middle of the extrusion pad 211, and side extrusion pads 2114 are symmetrically arranged on both sides of the main extrusion pad 2112, and an extrusion spring 2113 is fixedly installed on one side of the main extrusion pad 2112, and one end of the extrusion spring 2113 is fixedly connected to the inner wall of the extrusion pad 211, and a connecting rod 2115 is movably installed between the main extrusion pad 2112 and the side extrusion pad 2114, and the middle part of the connecting rod 2115 is rotatably connected to the inner side wall of the extrusion pad 211;

[0040] In this embodiment, as the squeezing pad 211 rotates, the squeezing spring 2113 is pulled by the centrifugal force, causing the main squeezing pad 2112 to be thrown out to hit the non-woven fabric, and then squeeze the non-woven fabric after contacting it.

Embodiment 3

[0041] See also Figures 1 to 12 On the basis of the second embodiment, in order to allow the lower layer of the non-woven fabric to be coated with glue before compounding, the present embodiment further proposes that the glue coating roller 31 is rotatably mounted on the inner side of the device frame 11, and a second motor 32 is fixedly mounted on the outer surface of the device frame 11, and the output shaft of the second motor 32 is fixedly connected to one end of the rotating shaft of the glue coating roller 31, and a pump 33 is provided on one side of the base 1, and a glue delivery pipe 34 is fixedly mounted on the output pipe of the pump 33, and the outer surface of the glue delivery pipe 34 penetrates the side wall of the device frame 11 and is rotatably connected to the other end of the rotating shaft of the glue coating roller 31, and the other end of the rotating shaft of the glue coating roller 31 is provided with a glue delivery pipe 34.

[0047] See also Figures 1 to 12 Based on the fifth embodiment, this embodiment further proposes a non-woven fabric composite method, comprising the following steps:

[0048] Step 1: The upper layer of the non-woven fabric is introduced through the material guide component 13, and the conveyor belt 12 transports the non-woven fabric;

[0049] Step 2: Connect the input pipe of the pump 33 to the supply pipe of the composite glue, and the pump 33 delivers and sprays the composite glue to the inside of the glue coating roller 31 through the glue delivery pipe 34.
