During operation, the driving mechanism drives the fixed gear 31 to rotate. The disc 32 is rotatably connected to the support block 28 through the rotating block 30. During the rotation of the disc 32, the connecting rod 34 will perform a circular motion along the center of the disc 32. The fixed block 33 fixed at the top of the connecting rod 34 slides in the movable frame 36. As the fixed block 33 slides on the movable frame 36, the movable frame 36 will reciprocally move in the front-rear direction.

When the second rack 60 reciprocates, the rotating gear 59 can rotate. The rear end of the rotating gear 59 is connected to the threaded rod 57, and the rear end of the threaded rod 57 is rotatably connected to the notch 58. The moving block 56 threadedly connected on the threaded rod 57 will move. The moving block 56 is connected to the first rack 54 through the long rod 55, and the first rack 54 is meshed with the fixed gear 31. Therefore, when the moving block 56 moves, the first rack 54 will drive the fixed gear 31 to rotate. The upper scraper 25 is provided with a notch 58, and the notch 58 contacts the moving block 56 to ensure that the moving block 56 does not rotate during movement. The bottom ends of the first rack 54 and the long rod 55 are both in contact with the support frame 53 to provide support for the movement of the first rack 54 and the long rod 55.

[0025] Further, the separation mechanism includes a connecting block 44, the connecting block 44 is fixedly connected to the scraper 40, one side of the connecting block 44 is fixedly connected to a fixed plate 42, the side of the connecting block 44 away from the scraper 40 is fixedly connected to a plug rod 45 and a spring 46, the spring 46 is sleeved on the plug rod 45, the side of the spring 46 away from the connecting block 44 is in contact with the long plate 50, the side of the plug rod 45 away from the connecting block 44 is rotatably connected to a pulley 47, the pulley 47 is slidably connected to the inside of a movable groove 49, and the movable groove 49 is opened on the long plate 50. 0, the front and rear sides of the long plate 50 are fixedly connected to the inner wall of the drying box 1, the inside of the movable groove 49 is fixedly connected with two groups of fixing strips 48, the spacing between the two groups of fixing strips 48 is slightly larger than the diameter of the insertion rod 45, the long plate 50 does not contact the abutment block 51, the abutment block 51 is fixedly connected to the upper scraper 25 and the lower scraper 26, the upper scraper 25 and the lower scraper 26 are provided with a rectangular groove 52 at a position close to the abutment block 51, the abutment block 51 is located below the fan 27, and the fan 27 is fixedly connected to the cover plate 20; The structural design of the separation mechanism is used to temporarily separate the scraper 40 from the upper scraper plate 25 and the lower scraper plate 26 during the resetting process of the scraper 40, so as to avoid that when the scraper 40 is reset, the other side of the scraper 40 will contact the surface of the upper scraper plate 25 and the lower scraper plate 26 again, causing the liquid to adhere to the back of the scraper 40, and ensure that only one side of the scraper 40 will contact the upper scraper plate 25 and the lower scraper plate 26 during the scraping process. When working, first when the scraper 40 moves backward, the scraper 40 can normally scrape one side of the upper scraper plate 25 and the lower scraper plate 26. When the scraper 40 moves backward to the maximum position, the fixed plate 42 will abut against the abutment block 51. 2 and the abutment block 51 are provided with inclined surfaces, the fixed plate 42 can be pushed smoothly, the spring 46 sleeved on the insertion rod 45 will be compressed, the insertion rod 45 and the pulley 47 will move a distance inside the movable groove 49, because two sets of fixed strips 48 are fixed inside the movable groove 49, the lower pulley 47 is in contact with one side of the fixed strip 48 in the initial state, when the fixed plate 42 is pushed by the abutment block 51, the scraper 40 fixed on the connecting block 44 will slide in the through groove 39, and the scraper 40 will also be separated from the upper scraper 25 and the lower scraper 26, and the pulley 47 moves inside the movable groove 49, causing the pulley 47 to contact the other side of the fixed strip 48 at this time, when the connecting plate 38 drives the scraper 40 to move forward When the scraper 40 is reset, the pulley 47 can abut against the other side of the fixed bar 48 to avoid the spring 46 from resetting, so that the scraper 40 will continue to remain separated from the upper scraper plate 25 and the lower scraper plate 26, thereby avoiding the other side of the scraper 40 from contacting the upper scraper plate 25 and the lower scraper plate 26 during the reset. When the scraper 40 moves back to its original position, the pulley 47 is not supported by the fixed bar 48, and the spring 46 will reset and push the scraper 40 to move, so that the scraper 40 continues to maintain contact with one side of the upper scraper plate 25 and the lower scraper plate 26 for the next scraping operation, wherein the two sets of fixed bars 48 do not contact each other and the spacing is greater than the diameter of the insertion rod 45, so as to facilitate the insertion of the rod 45 The front and rear sides of the fixed strip 48 do not contact the inner wall of the movable groove 49, and a certain distance is left between the inner wall of the movable groove 49, and the distance is larger than the diameter of the pulley 47 to ensure that the pulley 47 can move normally. The fan 27 is arranged above the abutment block 51. In addition to conveying gas to the interior of the drying box 1, the fan 27 can also blow the scraper 40 through the airflow of the fan 27, so that the liquid scraped off from the upper scraper plate 25 and the lower scraper plate 26 by the scraper 40 can fall off quickly. Through the design of the rectangular groove 52, when the scraper 40 moves backward to the maximum position, the liquid on the scraper 40 will not contact the upper scraper plate 25 and the lower scraper plate 26.

[0026] Further, the pushing mechanism includes a second rack 60, the second rack 60 is meshed with the rotating gear 59, the rear end of the second rack 60 is slidably connected to the guide block 63, the guide block 63 is fixedly connected to the front end of the drying box 1, the side of the second rack 60 away from the rotating gear 59 is fixedly connected to the push rod 61, the push rod 61 is rotatably connected to the connecting rod 62, the connecting rod 62 is rotatably connected to the rotating disk 67, the rotating disk 67 is fixedly connected to the rotating shaft of a group of conveying rollers 21, the bottom end of the second rack 60 is fixedly connected with a push plate 64, the push plate 64 is located below the lower scraper 26, the bottom end of the push plate 64 contacts the bottom end of the inner wall of the drying box 1, and two groups of discharge grooves 66 are opened on the bottom end of the drying box 1; Through the structural design of the pushing mechanism, when one group of conveying rollers 21 rotates, the second rack 60 can be driven to reciprocate, and the second rack 60 pushes the push plate 64 to move, and the push plate 64 can push the liquid scraped off from the upper scraper 25 and the lower scraper 26, so that the scraped liquid can be pushed to the discharge trough 66 for collection and cleaning of the liquid, thereby reducing the difficulty of subsequent cleaning.
