Description

Technical Field

[0001] This utility model relates to the field of coating machine feeding technology, and more specifically, it relates to a coating machine feeding device. Background Technology

[0002] Coating machines are mainly used for surface coating processes on films, paper, etc. This machine coats a roll of substrate with a specific functional adhesive, paint, or ink, dries it, and then rewinds it. The coating machine uses a dedicated multi-functional coating head, enabling various forms of surface coating. Both the unwinding and rewinding of the coating machine are equipped with a full-speed automatic film splicing mechanism, and the tension is automatically controlled by a PLC program in a closed-loop manner. A feeding device is required during the coating process. Existing coating machine feeding devices typically place the paint into a tank and then feed it. The tank usually has a stirring rod to agitate the paint, but the agitation method is relatively simple and prone to creating dead zones, thus reducing mixing efficiency. Secondly, existing coating machine feeding devices tend to have paint adhering to the tank during use, resulting in paint residue during feeding. Over time, the paint tends to solidify on the inner wall of the tank, making cleaning the device extremely difficult. Utility Model Content

[0028] Please see Figures 1-5A feeding device for a coating machine includes a material tank 1. A cover 2 is installed on the upper end of the material tank 1 by bolts and nuts. A feed hopper 3 is fixed on the material tank 1. A bracket 4 is fixed on the cover 2. A first motor 5 is fixed on the bracket 4. The drive end of the first motor 5 extends into the bracket 4 and is fixedly fitted with a screw 6. A drive rod 7 is threadedly connected to the screw 6. The two sides of the drive rod 7 are slidably connected to the bracket 4 through a track structure. An installation frame 8 is fixedly installed at the lower end of the drive rod 7. A second motor 9 is fixedly installed inside the installation frame 8. A rotating rod 10 is fixedly installed through the installation frame 8 at the drive end of the second motor 9. One end of the rotating rod 10 extends into the material tank 1 and is fixedly fitted with multiple stirring rods 11. A discharge pipe 23 is fixedly installed at the lower end of the material tank 1. A movable block 24 is fixedly installed at one end of the rotating rod 10.

[0029] In this embodiment, the paint is placed into the material cylinder through the feed hopper 3. The second motor 9 is started, which drives the rotating rod 10 to rotate. The rotating rod 10 drives the stirring rod 11 to rotate, stirring the paint in the material tank 1. At the same time, the first motor 5 is started, which drives the screw 6 to rotate. Since the screw 6 is threadedly connected to the drive rod 7, the drive rod 7 moves downward along the bracket 4. When the first motor 5 reverses, the drive rod 7 moves upward, causing the drive rod 7 to move up and down. The drive rod 7 drives the mounting frame 8 to move up and down, which in turn drives the second motor 9 to move up and down. The second motor 9 drives the rotating rod 10 to move up and down, which in turn drives the stirring rod 11 to move up and down. This up-and-down movement of the stirring rod 11 while rotating avoids dead zones in the stirring. While the rotating rod 10 is moving, it also drives the movable block 24 to move up and down, allowing the movable block 24 to clear the material in the discharge pipe 23 and prevent blockage.

[0030] Please see Figures 1-5 As one embodiment for scraping and cleaning the inner wall of the material tank 1: A turntable 12 is rotatably provided inside the cover 2 via a bearing. Two scrapers 13 are installed on the turntable 12. A square rod 14 is rotatably provided at the lower end of the mounting frame 8. The square rod 14 is fixedly connected to the rotating rod 10. One end of the square rod 14 extends into the material tank 1 and is movably connected to the turntable 12. A square hole 15 is provided on the turntable 12 to cooperate with the square rod 14. Two mounting slots 16 are provided on the turntable 12. A mounting seat 17 is movably provided in each mounting slot 16. One end of the mounting seat 17 passes through the mounting slot 16 and is fixedly connected to the scraper 13. A fixing chamber 18 is provided on one side of each mounting slot 16. A bidirectional lead screw 19 is rotatably provided in the fixing chamber 18. A handle 20 is fixedly provided at one end of the bidirectional lead screw 19 through the fixing chamber 18. Two moving plates 21 are threaded on the bidirectional lead screw 19. A fixing block 22 is fixedly provided on one side of each moving plate 21. One end of the fixing block 22 is inserted into the mounting seat 17.

[0031] More specifically, when it is necessary to scrape and clean the inner wall of the material tank 1, the cover 2 is provided with a round hole that mates with the square rod. While the mounting frame 8 moves up and down, the mounting frame 8 drives the square rod 14 to move up and down. At the same time, the square rod 14 rotates with the rotation of the rotating rod 10. The square rod 14 drives the turntable 12 to rotate around the rotational connection with the cover 2 through the square hole 15. The turntable 12 drives the installed scraper 13 to rotate, so that the scraper 13 scrapes and cleans the inner wall of the material tank 1. When it is necessary to disassemble, repair and replace the scraper 13, the cover 2 is separated from the material tank 1 by removing the bolts and nuts. The handle 20 is turned, and the handle 20 drives the double-acting screw 19 to rotate. Since the double-acting screw 19 is provided with two threaded areas in opposite directions, the two moving plates 21 are moved. The moving plates 21 drive the fixed block 22 to move, so that the fixed block 22 is separated from the mounting base 17. The scraper 13 can be removed by pulling it. The replacement scraper 13 can be installed by using the reverse operation.

[0032] In summary, during the use or operation of the overall equipment: The paint is placed into the material cylinder through the feed hopper 3. The second motor 9 is started, which drives the rotating rod 10 to rotate. The rotating rod 10 drives the stirring rod 11 to rotate, stirring the paint in the material tank 1. Simultaneously, the first motor 5 is started, which drives the screw 6 to rotate. Since the screw 6 is threadedly connected to the drive rod 7, the drive rod 7 moves downward along the bracket 4. When the first motor 5 reverses, the drive rod 7 moves upward, causing it to move up and down. The drive rod 7 drives the mounting frame 8 to move up and down, which in turn drives the second motor 9 to move up and down. The second motor 9 drives the rotating rod 10 to move up and down, which in turn drives the stirring rod 11 to move up and down. This up-and-down movement of the stirring rod 11 while it rotates avoids dead zones in the mixing process. Simultaneously, the rotating rod 10 drives the movable block 24 to move up and down, allowing the movable block 24 to clear the material in the discharge pipe 23 and prevent blockage.

[0033] When it is necessary to scrape and clean the inner wall of the material tank 1, the cover 2 is provided with a round hole that mates with the square rod. While the mounting frame 8 moves up and down, the mounting frame 8 drives the square rod 14 to move up and down. At the same time, the square rod 14 rotates with the rotation of the rotating rod 10. The square rod 14 drives the turntable 12 to rotate around the rotational connection with the cover 2 through the square hole 15. The turntable 12 drives the installed scraper 13 to rotate, so that the scraper 13 scrapes and cleans the inner wall of the material tank 1. When it is necessary to disassemble, repair and replace the scraper 13, the cover 2 is separated from the material tank 1 by removing the bolts and nuts. The handle 20 is turned, and the handle 20 drives the double-acting screw 19 to rotate. Since the double-acting screw 19 is provided with two threaded areas in opposite directions, the two moving plates 21 are moved. The moving plates 21 drive the fixed block 22 to move, so that the fixed block 22 is separated from the mounting base 17. The scraper 13 can be removed by pulling it. The replacement scraper 13 can be installed by using the reverse operation.
