[0038] Example 2

[0039] See Figure 1-7Furthermore, based on Embodiment 1, the coating mechanism 3 includes a rectangular groove 304, which is formed inside the top plate 2. There are two rectangular grooves 304, with openings at the top and bottom. Slide grooves 39 are formed on the front and rear sides of the inner wall of the rectangular groove 304. A square base 305 is fixedly connected to the top right side of the top plate 2. An electric push rod 31 is fixedly connected to the left side of the square base 305. A connecting plate 32 is fixedly connected to the left side of the electric push rod 31. Connecting boxes 36 are fixedly connected to both ends of the left side of the connecting plate 32. The surface of the connecting box 36 is inserted into the inside of the rectangular groove 304. Slider 38 is fixedly connected to the front and rear sides of the connecting box 36. The surface of the slider 38 is connected to the inside of the slide groove 39. A sliding connection is used. A water pump 35 is fixedly connected to the center of the left side of the connecting plate 32. A material pipe 33 is fixedly connected to the left side of the water pump 35. A first diversion pipe 34 is fixedly connected to the top of the water pump 35. A discharge pipe 37 is fixedly connected to both ends of the bottom of the first diversion pipe 34. The discharge pipe 37 is located inside the connecting box 36. A second diversion pipe 301 is fixedly connected to the bottom of the connecting box 36. A nozzle 303 is densely fixedly connected to the bottom of the second diversion pipe 301. A connecting seat 302 is fixedly connected to the outside of the two discharge pipes 37. There are two connecting seats 302. The two connecting seats 302 are located at the bottom of the top plate 2. The inside of the two connecting seats 302 is fixedly connected to the second diversion pipe 301.

[0040] Furthermore, the material pipe 33 is connected to an external container for loading coating. When the water pump 35 is started, the material pipe 33 can transport the coating to the first diversion pipe 34 and then divert it into two outlet pipes 37. After that, the coating in the two outlet pipes 37 is combined through the second diversion pipe 301 until the nozzle 303 coats the surface of the artificial leather. When the electric push rod 31 is running, it drives the connecting plate 32 to move. The connecting plate 32 drives the connecting box 36, which can coat different positions on the surface of the artificial leather.

[0041] In actual operation, when this device is used, since the material pipe 33 is connected to the external container for loading coating, when the water pump 35 is started, the material pipe 33 can transport the coating to the first diversion pipe 34 and then divert it to the two outlet pipes 37. Then, the coating in the two outlet pipes 37 is combined through the second diversion pipe 301 until the nozzle 303 coats the artificial leather surface.

[0042] The electric push rod 31 drives the connecting plate 32 to move, the connecting plate 32 drives the connecting box 36, and the connecting box 36 drives the slider 38 to slide in the slide groove 39, which can coat different positions on the surface of the artificial leather.

[0043] When the two ends of the artificial leather are partially wound around the surface of the roller 421, the spring 428 can move the mounting plate 423 under the rebound force of the spring 428. The mounting plate 423 drives the pressing ring 422 to press and fix the artificial leather wound on the surface of the roller 421. Under the stretching of the telescopic plate 424, it is inserted into the slot 425, which can fix the pressing ring 422 on the surface of the artificial leather, making it convenient to fix the artificial leather on the top of the workbench 1.

[0044] When the dual-axis motor 414 starts, it drives the worm gear 413 to rotate, and the worm wheel 415 rotates on the surface of the worm gear 413. At the same time, the worm wheel 415 drives the bidirectional threaded rod 411 to rotate, and the two moving plates 412 move to opposite sides on the surface of the bidirectional threaded rod 411. When the moving plates 412 move, they can drive the fixed seat 417. The fixed seat 417 drives the T-block 418 to slide in the T-slot 419, which can tension the artificial leather and avoid wrinkles on the surface of the artificial leather, making it easier to apply a more even surface coating.
