[0018] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0020] The liquid resin material is located in the glue tank 4 . When the glue roller 2 rotates, the outer surface of the glue roller 2 is immersed in the liquid resin material in the glue tank 4 , and then the resin material adhered to the outer surface of the glue roller 2 is transferred to the outer surface of the non-woven fabric 32 .

[0021] The feed roller 5 and the discharge roller 6 are used to control the feeding and discharging of the non-woven fabric 32, and after passing through the feed roller 5 and the discharge roller 6, the moving direction of the non-woven fabric 32 is opposite to the incoming direction, which can also reduce the floor space. The squeezing roller 3 cooperates with the steering roller 7 to make the non-woven fabric 32 tightly attached to the outer surface of the squeezing roller 3, so that the glue coating roller 2 can stably coat the resin material on the outer surface of the non-woven fabric 32. The steering roller 7 is used to change the moving direction of the non-woven fabric 32 in the glue coating box 1, and can be used to control the thickness of the resin material layer on the surface of the non-woven fabric 32 by cooperating with the scraper plate 8, scrape off excess resin material from the non-woven fabric 32, and improve the quality consistency of the water-blocking tape product.

[0022] The output end of the driving motor 9 and the outer end of the glue coating roller 2 are both provided with a pulley 10, and the two pulleys 10 are driven by a belt 11, so that the rotation of the glue coating roller 2 can be controlled. In the glue coating box 1, only the interior of the glue storage tank 4 stores the resin material for a long time. After the scraper plate 8 scrapes off the excess resin material on the non-woven fabric 32, the resin material randomly falls to the position below the steering roller 7. Since this position is a certain distance away from the glue storage tank 4, the resin material of this part cannot be fully utilized. Therefore, the driving motor 9 can drive the extension rod 12 to rotate, and the extension rod 12 drives the eccentric rod 15 to move in the slide groove 25 of the second connecting rod 23 through the turntable 14, and through the cooperation of the first connecting rod 22 and the guide rod 21, it can drive the push rod 16 to do reciprocating motion in the glue coating box 1. The push rod 16 tilts and moves downward in the glue coating box 1. When the push rod 16 moves, it drives the push plate 17 to move. When the push plate 17 moves in the direction close to the glue storage tank 4, the resin material under the steering roller 7 can be pushed When the push plate 17 moves in the direction away from the glue groove 4, the resin material under the steering roller 7 will be brought away from the glue groove 4. In order to make the resin material under the steering roller 7 only be pushed in the direction of the glue groove 4, the push plate 17 can be controlled to rotate by cooperating with the elastic rod 20. That is, when the push plate 17 moves in the direction of the glue groove 4, the push plate 17 can be kept perpendicular to the glue coating box by the elastic belt 18 and the stop block 19. 1, both ends of the push plate 17 are at a distance from the two side walls of the glue coating box 1. When the push plate 17 moves in the direction away from the glue containing groove 4, the elastic rod 20 can deflect the push plate 17 and make the lower end of the push plate 17 continue to move away from the lower surface of the glue coating box 1, so as to prevent the push plate 17 from bringing the resin material under the steering roller 7 away from the position farther from the glue containing groove 4. Since the elastic rod 20 can be bent, it will not affect the normal movement of the push plate 17 towards the glue containing groove 4.

[0023] Furthermore, a rotating shaft 26 is provided at the bottom of the glue tank 4, and stirring brushes 27 are arranged evenly on the rotating shaft 26. The glue roller 2 and the rotating shaft 26 are driven by a gear 28. The ends of the glue roller 2 and the rotating shaft 26 are provided with gears 28. The glue roller 2 and the rotating shaft 26 are externally meshed by the gear 28, so that the rotating shaft 26 can be driven to rotate. When the rotating shaft 26 rotates, the stirring brush 27 can prevent the resin material at the bottom of the glue tank 4 from precipitating, and the stirring brush 27 can cover the glue roller 2. As the resin material in the glue tank 4 is used more and more, the stirring brush 27 can prevent the glue roller 2 from precipitating. When the amount of resin material is too little to come into direct contact with the glue coating roller 2, the resin material can be applied to the outer surface of the glue coating roller 2 by means of a stirring brush 27, and the number of teeth of the gear 28 on the glue coating roller 2 is greater than the number of teeth of the gear 28 on the rotating shaft 26, so the rotation speed of the rotating shaft 26 is faster, and the resin material can be transferred to the outer surface of the glue coating roller 2 by means of the stirring brush 27, and the rotation directions of the glue coating roller 2 and the stirring brush 27 are opposite, and the thickness of the resin material on the surface of the glue coating roller 2 can be reduced by means of the stirring brush 27, so as to reduce the scraping pressure of the subsequent scraper 8.

[0024] Furthermore, a heating device 29 is provided on one side of the glue containing groove 4, and the heating device 29 can heat the resin material in the glue containing groove 4 to improve the fluidity of the resin material and prevent it from being too viscous and affecting coating.

[0025] Furthermore, a glue injection port 30 is provided on one side of the glue coating box 1 , and resin material is injected into the glue containing groove 4 through the glue injection port 30 .

[0026] Furthermore, a top cover 31 is provided above the discharge roller 6, and the exposed area directly above the glue coating box 1 can be reduced by the top cover 31. The top cover 31 can be set to a telescopic shape, which can completely cover the upper end opening of the glue coating box 1 to reduce the entry of dust and impurities into the glue coating box 1.

[0027] Working principle: When the non-woven fabric 32 moves in the glue coating box 1, the resin material is coated on the outer surface of one side of the non-woven fabric 32 through the glue coating roller 2, and then the thicker resin material on the non-woven fabric 32 is reduced to a suitable thickness through the cooperation of the scraper plate 8 and the steering roller 7. The scraped resin material falls under the steering roller 7, and the driving motor 9 drives the guide rod 21 and the push rod 16 to move back and forth in the glue coating box 1 through the cooperation of the extension rod 12, the turntable 14, the eccentric rod 15, the slide groove 25 on the second connecting rod 23 and the first connecting rod 22, and pushes the resin material under the steering roller 7 to the direction close to the glue containing groove 4 through the push plate 17, and then the push plate 17 does not take the resin material away from the glue containing groove 4 when it is away from the glue containing groove 4 through the cooperation of the elastic rod 20 and the push plate 17.

[0028] The device can scrape off excess resin material from the non-woven fabric 32 and push it into the glue tank 4 in a timely manner through the push plate 17, and can effectively prevent the resin material from adhering to the bottom of the glue coating box 1 below the steering roller 7, so that the resin material can be fully used and the waste of resin material can be reduced. In addition, through the rotating shaft 26 and the stirring brush 27, it can prevent the resin material in the glue tank 4 from precipitating, and when the resin material in the glue tank 4 is insufficient, the resin material can be applied to the outer surface of the glue coating roller 2 by brushing, and the use effect is good.
