Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of needle felt processing, and specifically relates to a device for uniformly impregnating a water-repellent auxiliary agent for needle felt. Background Art
[0002] At present, the water-repellent effect given to needle-punched felt is mainly achieved by impregnating the needle-punched felt with a slurry tank filled with water-repellent and oil-proof additives, and then entering the squeezing roller under the stretching of the transmission device to squeeze out the excess liquid contained in the needle-punched felt. In this process, the amount of liquid in the slurry tank in the transverse width direction of the felt body and the squeezing force of the squeezing roller in the transverse width direction of the felt body are different, resulting in different amounts of liquid at different positions in the width direction, resulting in differences in water-repellent effect. This difference may lead to a deterioration in the uniformity of the water-repellent effect. Since the amount of liquid and the squeezing force cannot be fully controlled, the water-repellent effect will be unstable, which will affect the reliability of the needle-punched felt. Therefore, we propose a uniform impregnation device for water-repellent additives for needle-punched felt. Utility Model Content

[0015] When giving the needle felt a water-repellent effect, the box 1 is used to support and fix the slurry tank 2, and the water-repellent and oil-proof additive is poured into the slurry tank 2 in advance to ensure that the amount of liquid in the slurry tank is appropriate to ensure a uniform impregnation effect. Then the needle felt is wound around the outer wall of the second inner roller 4. At the same time, a first inner roller 3 is also provided inside the slurry tank 2. At the same time, the needle felt is fitted with the first inner roller 3 and stretched by the first inner roller 3 so that the needle felt is soaked in the slurry tank 2.
