Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In practical implementation: such as Figures 1-4 As shown, a surface coating device for composite needle-punched felt includes: a housing 100, a coating nozzle 200 fixedly connected inside the housing 100, and a driven roller 110 rotatably connected to the housing 100 on one side of the coating nozzle 200.

[0028] As shown in Figure 1 , Figure 3 and Figure 4 , two first cylinders 350 are arranged between the adjusting block 340 and the moving frame 330, the top end of the first cylinder 350 is fixedly connected to the adjusting block 340, the top end of the adjusting block 340 is slidingly connected to the inner wall of the support frame 310, the inner wall of the support frame 310 is rotationally connected with a threaded rod 380, one end of the threaded rod 380 is provided with a driving motor 390, the driving motor 390 is fixedly connected to the support frame 310, the driving end of the driving motor 390 is fixedly connected to one end of the threaded rod 380, the top end of the adjusting block 340 is arranged on the surface of the threaded rod 380, the inner wall of the first cylinder 350 is slidingly connected with a first piston 351, the first piston 351 penetrates out of the first cylinder 350 and is fixedly connected to the moving frame 330, the two first cylinders 350 are connected in communication through an air pipe, the inner wall of the support frame 310 is fixedly connected with a second cylinder 360, the second cylinder 360 is connected in communication with the air pipe, the inner wall of the second cylinder 360 is slidingly connected with a second piston 361, the bottom end of the second piston 361 is fixedly connected with a spring 362 between the inner bottom wall of the second cylinder 360, the outer surface of the support frame 310 is fixedly connected with an air pump 370, and the air pump 370 is connected in communication with the second cylinder 360.

[0029] The communication points of the two first cylinders 350 are located in the chamber formed between the first piston 351 and the inner bottom wall of the second cylinder 360, and the communication points of the second cylinder 360 and the air pump 370 and the two first cylinders 350 are located in the chamber formed between the second piston 361 and the inner top wall of the second cylinder 360. When it is necessary to coat the thicker needle punching felt, in order to prevent the pressure of the limiting roller 320 on the needle punching felt from being too large, the air pump 370 is needed to fill air into the second cylinder 360, at this time, the pressure in the second cylinder 360 increases, and the spring 362 and the second piston 361 are matched to pass part of the gas into the two first cylinders 350, the pressure in the chamber between the first piston 351 and the inner bottom wall of the first cylinder 350 increases, the first piston 351 is extruded upwards, so as to reduce the pressure of the limiting roller 320 on the needle punching felt. When it is necessary to coat the thinner needle punching felt, the air in the second cylinder 360 is extracted through the air pump 370, and the principle is opposite to the above.

[0031] In this embodiment, before the needle punching felt is coated, it needs to be wound on the winding roller 120 first, and then the movable end passes below the flattening roller 130, so that the needle punching felt is taut and the probability of wrinkles on the surface is reduced, and then passes between the driven roller 110 and the limiting roller 320, and then passes through the coating nozzle 200, and then is fixed to the collecting roller 140, the collecting roller 140 is driven to rotate by the motor, and the needle punching felt is moved by the rotation of the collecting roller 140, so as to be coated.

[0032] When the needle punching felt passes between the limiting roller 320 and the driven roller 110, the pressure in the first cylinder 350 is adjusted by adjusting the pressure in the second cylinder 360 through the air pump 370, so as to adjust the pressure of the first piston 351 on the needle punching felt, so that the limiting roller 320 applies appropriate pressure to the needle punching felt, so that it stably passes between the driven shaft and the limiting roller 320.

[0033] When the needle felt position deviates from the preset position, the rotation direction of the driving motor 390 is selected according to the direction of its deviation, thereby driving the threaded rod 380 to rotate, and the adjusting block 340 is moved transversely through the rotation of the threaded rod 380, thereby driving the limiting roller 320 to move transversely, and through the friction between the limiting roller 320 and the surface of the needle felt, the needle felt is driven to slide transversely on the surface of the driven roller 110, thereby returning to the right track.
