Description

Technical Field

[0001] The utility model relates to the technical field of dipping equipment, in particular to a non-woven fabric dipping equipment. Background Art

[0002] Non-woven fabric is a kind of fabric that does not require spinning and weaving. It is simply a directional or random arrangement of textile short fibers or filaments to form a fiber mesh structure, which is then reinforced by mechanical, thermal bonding or chemical methods. In order to improve the mechanical properties of non-woven fabrics, it is generally necessary to dip the non-woven fabric in glue so that the surface and gaps of the non-woven fabric are filled with glue. After the glue solidifies, the non-woven fabric will have strong mechanical properties. When dipping, the non-woven fabric needs to be completely immersed in the glue. In order to facilitate the penetration of the glue, a low-solid content glue is generally used. Although low-solid content glue can easily penetrate the non-woven fabric, it contains more water, and the subsequent drying process takes longer and uses more energy. After the non-woven fabric is dipped in glue with a high-solid content glue, the drying time of the non-woven fabric is shorter, but it is not easy to penetrate the non-woven fabric, resulting in poor dipping effect.

[0027] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] like Figure 1 and Figure 2As shown, a non-woven fabric dipping device includes a dipping tank 1, a conveyor roller 2, a vacuum box 3 and a vacuum pump 6. The upper end of the dipping tank 1 is an open structure. The interior of the dipping tank 1 is filled with glue for dipping. The glue is a high-solid content glue. The conveyor roller 2 is rotatably arranged in the dipping tank 1. There are two conveyor rollers 2, which are horizontally arranged. The conveyor rollers 2 are completely immersed in the glue. The fabric is wound between the two conveyor rollers 2, so that the fabric can be completely flattened between the two conveyor rollers 2, which is convenient for the adhesion and immersion of the glue. The vacuum box 3 is fixedly arranged at the dipping tank. In the pool 1, the glue completely immerses the vacuum box 3, and a vacuum cavity is provided inside the vacuum box 3. An adsorption plate 4 is fixedly provided on one side of the vacuum box 3. A plurality of suction holes 5 are provided on the adsorption plate 4. The suction holes 5 are connected to the vacuum cavity. The surface of the adsorption plate 4 in contact with the cloth is polished to make the surface smoother and will not scratch the cloth. An air suction pipe 7 is connected to the vacuum box 3, and the air suction pipe 7 is connected to the vacuum cavity. One end of the air suction pipe 7 extends to the outside of the dipping pool 1 and is connected to the input end of the vacuum pump 6. The output end of the vacuum pump 6 is connected to the dipping pool 1 through a connecting pipe. In the present invention, during the process of impregnation of the cloth, the cloth is completely immersed in the glue after being conveyed by the conveying roller 2. As the cloth is continuously conveyed, one side of the cloth contacts the adsorption plate 4, and the vacuum pump 6 sucks air to evacuate the vacuum chamber through the suction pipe 7. Since the suction hole 5 is connected with the vacuum chamber, the cloth can be adsorbed on the adsorption plate 4, and the glue on the side of the cloth away from the adsorption plate 4 can pass through the cloth and be sucked into the vacuum chamber. The glue impregnates the cloth when passing through the cloth, and the glue in the vacuum chamber can be transported back to the dipping tank 1 from the connecting pipe after being sucked by the vacuum pump 6, so as to avoid waste of glue. Since the glue is a glue with a high solid content, it has a low water content, and the subsequent drying is faster, which reduces the use of energy.

[0031] In another embodiment, there are two vacuum boxes 3 and two adsorption plates 4, which are respectively located on both sides of the cloth, and the two vacuum boxes 3 are staggered. In this embodiment, during the cloth conveying process, the two vacuum boxes 3 are respectively located on both sides of the cloth and the two vacuum boxes 3 are staggered. Each vacuum box 3 is provided with an adsorption plate 4, so that the glue can pass through both sides of the cloth, thereby improving the glue impregnation effect.

[0032] In another embodiment, Figure 3As shown, it also includes a glue squeezing component, which includes a frame 8, which is fixedly arranged above the dipping tank 1, and a fixed squeezing roller 9 and a dynamic squeezing roller 10 are rotatably arranged on the frame 8, and the fixed squeezing roller 9 is driven to rotate by a motor fixedly arranged on the frame 8, and a lifting plate 11 is slidably arranged on the frame 8, and the dynamic squeezing roller 10 is rotatably arranged on the lifting plate 11, and the cloth is located between the fixed squeezing roller 9 and the dynamic squeezing roller 10; in this embodiment, the position of the fixed squeezing roller 9 remains unchanged, and the distance between the fixed squeezing roller 9 and the dynamic squeezing roller 10 can be adjusted by adjusting the position of the lifting plate 11, and when the cloth passes between the fixed squeezing roller 9 and the dynamic squeezing roller 10, it can be squeezed by the fixed squeezing roller 9 and the dynamic squeezing roller 10 to squeeze out excess glue in the cloth, and the squeezed glue can drip from the cloth back into the dipping tank 1, so that the glue is recycled and reused to avoid glue waste.

[0033] Furthermore, a threaded rod 12 is threadedly connected to the frame 8, and one end of the threaded rod 12 is rotatably connected to the lifting plate 11. By rotating the threaded rod 12, the lifting and lowering of the threaded rod 12 on the frame 8 is controlled, and then the lifting plate 11 is driven to rise and fall on the frame 8, thereby realizing the distance adjustment between the fixed squeezing roller 9 and the movable squeezing roller 10.

[0034] In another embodiment, two squeezing rollers are rotatably provided on the frame 8, and the positions of the two squeezing rollers on the frame 8 are fixed, so the distance between the two squeezing rollers cannot be adjusted. The cloth is located between the two squeezing rollers, so the cloth can be squeezed by the two squeezing rollers when passing through the two squeezing rollers to squeeze out excess glue.

[0035] In another embodiment, a blowing nozzle 13 is provided above the dipping tank 1, and two blowing nozzles 13 are provided. The two blowing nozzles 13 are respectively located on both sides of the cloth, and the outlet end of the blowing nozzle 13 faces one side of the cloth. The blowing direction of the blowing nozzle 13 is inclined to the side of the cloth, and the blowing nozzle 13 is connected to a blowing pipe 14. One end of the blowing pipe 14 is connected to an air compressor, and high-pressure air can be sent into the blowing pipe 14. After the high-pressure air enters the blowing pipe 14, it is discharged from the outlet end of the blowing nozzle 13 and blown toward the cloth, so that the residual glue on the cloth can be blown off, and the glue falls back from the cloth into the dipping tank 1, and the glue is recycled.

[0036] Furthermore, a guide roller 15 is rotatably provided above the dipping tank 1 for guiding the cloth.

[0037] Furthermore, a liquid level gauge 16 is fixedly provided on the top of the dipping tank 1. The liquid level gauge 16 is an ultrasonic liquid level gauge, which is used to detect the liquid level of the glue solution, so that the glue solution in the dipping tank 1 remains stable. When the glue solution level is low, glue can be replenished in time.

[0038] Furthermore, a pressure sensor 17 is provided on the suction pipe 7. The pressure sensor 17 can detect the pressure in the suction pipe 7, so as to facilitate the adjustment of the air pressure in the vacuum box 3 and better achieve the dipping of glue.

[0039] Furthermore, a cylinder is fixedly installed in the dipping pool 1, and the vacuum box 1 is fixedly installed on the piston rod of the cylinder. The distance between the two vacuum boxes 1 can be adjusted by extending and retracting the piston rod of the cylinder to meet the dipping requirements of non-woven fabrics of different thicknesses.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
