DETAILED DESCRIPTION

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the protection scope and application scope of the present invention are not limited.

[0018] Embodiment 1: A coating machine, such as Figure 1-Figure 5 As shown, it includes a frame 1, a first roller 2 and a second roller 3. The first roller 2 and the second roller 3 are rotated at an interval on the front side of the frame 1. A motor 5 is installed on the right side of the frame 1. The output shaft of the motor 5 is fixedly connected to one end of the first roller 2. A collection box 4 is fixedly connected to the frame 1 below the first roller 2. A stirring component is arranged in the collection box 4. A preparation box 6 is fixedly connected to the front side of the collection box 4. A feed port 601 is provided on the top of the preparation box 6. A discharge port 602 is provided on the rear side of the preparation box 6. The discharge port 602 is connected to the inside of the collection box 4. An opening and closing component for controlling the opening and closing of the discharge port 602 based on the liquid level is arranged in the collection box 4.

[0019] The stirring assembly includes a stirring rod 501 and a synchronous belt assembly 502. Two stirring rods 501 are rotatably connected in the collecting box 4. The left end of the first roller 2 and the left rod end of the stirring rod 501 are transmission-connected through a synchronous belt assembly 502. The synchronous belt assembly 502 includes three synchronous wheels and a synchronous belt. The left end of the first roller 2 and the left rod ends of the two stirring rods 501 are respectively fixed to a synchronous wheel, and the synchronous belt is wound around the three synchronous wheels.

[0020] The feeding assembly includes a floating plate 701 and a stopper 703. The floating plate 701 is slidably connected to one side of the collecting box 4 near the discharge port 602. A groove 702 is opened on the floating plate 701 near the discharge port 602. A stopper 703 is fixedly connected to the lower part of the groove 702 on the floating plate 701.

[0021] The working principle of this embodiment is as follows: before the coating operation, the coating is added through the feed port 601 of the material preparation box 6, and flows into the collection box 4 from the discharge port 602. The liquid level in the collection box 4 gradually rises, and the float plate 701 rises with the liquid level. When the liquid level reaches a preset height, the block 703 on the float plate 701 will block the discharge port 602 to prevent the coating from continuing to flow into the collection box 4. During the coating process, the cloth is passed between the first roller 2 and the second roller 3. The first roller 2 is driven to rotate by the motor 5, and the second roller 3 cooperates with the first roller 2 to clamp. The first roller 2 is used as a coating roller to evenly coat the coating on the cloth. At the same time, the first roller 2 drives the stirring rod 501 to rotate through the synchronous belt assembly 502, and continuously stirs the paint in the collection box 4 to ensure the uniformity of the paint; as the coating operation proceeds, the paint in the collection box 4 gradually decreases, the liquid level gradually decreases, and the floating plate 701 decreases with the decrease in the liquid level. When the block 703 no longer blocks the discharge port 602, the paint in the preparation box 6 automatically flows from the discharge port 602 into the collection box 4 for replenishment. After the paint in the collection box 4 is replenished, the liquid level rises again, and the block 703 on the floating plate 701 blocks the discharge port 602 again, thereby realizing the automatic replenishment cycle of the paint.

[0022] Embodiment 2: Based on embodiment 1, a coating machine, such as Figure 1-Figure 5 As shown, it also includes a slider 10, and both ends of the second roller shaft 3 are slidably connected to the frame 1 through the slider 10. A screw rod 11 is fixedly connected to the slider 10, and the screw rod 11 is threadedly connected to the frame 1. The upper ends of the two screw rods 11 are transmission connected through a synchronous belt assembly 12. The synchronous belt assembly 12 includes two synchronous wheels and a synchronous belt. The upper ends of the two screw rods 11 are respectively fixedly connected to a synchronous wheel, and the synchronous belt is wound around the two synchronous wheels. The upper end of the screw rod 11 on the right side is fixedly connected to a driving member 13, and the driving member 13 is a crank rod.

[0023] The machine frame 1 also includes a distance sensor 14 . The distance sensor 14 is fixedly disposed on the left side of the machine frame 1 . The distance sensor 14 is used to monitor the distance between the first roller 2 and the second roller 3 .

[0024] It also includes a waste box 8 and a scraper 9. The waste box 8 is slidably connected to the top of the material preparation box 6, and the scraper 9 is fixedly connected to one side of the waste box 8 close to the first roller 2.

[0025] The working principle of this embodiment is as follows: the screw 11 connected to it is driven to rotate by the driving member 13, and the screw 11 drives another screw 11 to rotate synchronously through the synchronous belt assembly 2 12, so that the two screws 11 are synchronously raised or lowered on the frame 1, and this movement drives the slider 10 and the second roller 3 to rise or fall, thereby adjusting the distance between the second roller 3 and the first roller 2, so that the coating machine can adapt to the coating requirements of fabrics of different thicknesses, thereby improving the flexibility and adaptability of the coating machine; after the coating operation is completed, the waste box 8 is moved close to the first roller 2 until the scraper 9 contacts the first roller 2, and the first roller 2 is driven to rotate by the motor 5. During the contact process, the scraper 9 can promptly scrape off the paint on the surface of the first roller 2 to prevent the paint from remaining on the surface of the first roller 2 and affecting the subsequent coating effect. The paint scraped off by the scraper 9 will naturally fall into the waste box 8 by gravity for collection.

Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the utility model concept of the present invention.
