[0035] The utility model provides a kind of impregnation device for producing water-repellent nonwoven fabric, including: input roller 100, impregnation pool 200 and output roller 300 are sequentially arranged along production direction;

[0036] As Figure 1 Indicated, the utility model provides a kind of impregnation device for producing water-repellent nonwoven fabric, including: input roller 100, impregnation pool 200 and output roller 300 are sequentially arranged along production direction;

[0037] Still be provided with the pressure roller 400 that nonwoven fabric lower surface meets with the water-repellent agent surface in impregnation pool 200;Spray assembly 500 is arranged on the upper surface of nonwoven fabric in impregnation pool 200 and is sprayed with water-repellent agent, impregnation pool 200 is communicated with spray assembly 500 by the liquid outlet of bottom opening.

[0038] Specifically, input roller 100, impregnation pool 200 and output roller 300 are sequentially arranged from left to right along production direction, so that nonwoven fabric enters from the top end of input roller 100, after the bottom of several pressure rollers 400 arranged in impregnation pool 200, from the top end of output roller 300 moves out;Input roller 100 and output roller 300 are in the form of roller, impregnation pool 200 is in the form of rectangle, through hole is opened at the top of the front and rear sides of impregnation pool 200, two pressure rollers 400 pass through the two sides of impregnation pool 200 and are arranged in impregnation pool 200.In impregnation pool 200, the height of water-repellent agent added is close to pressure roller 400, so that the lower surface of nonwoven fabric can contact with water-repellent agent in impregnation pool 200, water-repellent agent is fully contacted with the bottom of nonwoven fabric, and the nonwoven fabric with high water repellency is formed, while the upper surface is upward and does not immerse into impregnation pool 200, and floats on the surface of water-repellent agent.

[0039] The spraying assembly 500 is communicated with the communicating spraying pipe, and the repellent flows into the spraying pipe; the immersion tank 200 is further communicated with the spraying assembly 500 through the liquid outlet formed in the bottom, when the repellent sprayed by the spraying assembly 500 on the top is too much, causing the repellent water level in the immersion tank 200 to rise, the repellent is pumped away through the liquid outlet formed on one side of the bottom of the immersion tank 200 and is retransmitted to the spraying assembly 500, and the spraying assembly 500 is used for spraying the repellent on the upper surface of the non-woven fabric again, so that the effect of recycling can be realized, the cost is saved, the waste is prevented, and the repellent water level is prevented from exceeding the press roller 400, so that the repellent in the immersion tank 200 can only soak the lower surface of the non-woven fabric; the spraying assembly 500 is arranged above the immersion tank 200, and the spraying assembly 500 is used for spraying the repellent on the upper surface of the non-woven fabric from the top; because the content of the repellent sprayed is small, the repellency of the upper surface of the non-woven fabric is weaker than that of the soaked lower surface, so that the repellency of the upper and lower layers of the non-woven fabric is different, and the non-woven fabric is suitable for sanitary nursing supplies; the outer layer fabric needs to have good repellency to prevent liquid leakage, and the inner layer in contact with the skin needs to have weaker repellency than the outer layer, so as to be in contact with the skin.

[0043] When the non-woven fabric soaked absorbs the repellent, the water level in the immersion tank 200 drops, that is, the preset height does not reach the level of the press roller 400, the second water level sensor 202 controls the liquid inlet to be opened through the electric signal, and the repellent is supplemented in the immersion tank 200, so as to replace the traditional manual pouring into the tank, and the labor cost is saved. Furthermore, the press roller 400 can be cooperated with, so that the non-woven fabric can float on the upper part of the repellent water surface, and the lower surface is fully soaked under the action of the downward pressure of the press roller 400.

[0044] When the water repellent agent sprayed by the upper spraying assembly 500 is too much, causing the water level in the immersion pool 200 to rise, that is, exceed the preset height of the water level flush with the press roller 400, the first water level sensor 201 controls the water pump in the spraying assembly 500 to suck water through an electrical signal, restores the water surface to the preset height, and can re-spray the discharged water repellent agent on the upper surface of the non-woven fabric. While spraying the upper surface of the non-woven fabric, compared with directly discharging from the liquid outlet, economic cost is saved.

[0050] The bottom end of the water feeding pipe 503 is communicated with the water pumping pump 502 and the spraying pipe, when the water level does not exceed the preset height, the spraying head 505 is supplied with the water repellent agent through the spraying pipe and the water feeding pipe 503, and when the water level exceeds the preset height, the spraying head 505 is supplied with the water repellent agent by the water pumping pump 502.

[0051] The end of the water feeding pipe 503 is communicated with the spraying head 505 through an elbow, so that the direction of the spraying head 505 is just downward, and the sprayed water repellent agent is sprayed on the upper surface of the non-woven fabric. The control valve 504 is arranged on the water feeding pipe 503 and is used to control the opening and closing of the spraying head 505, and it can accurately control the water flow to ensure that the spraying head can spray the water repellent agent when needed.
