[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.
[0019] Please see Figures 1 to 7 This invention provides a technical solution: a drying device for ink printing on paper packaging boxes, comprising: a baking oven 1, a first conveyor belt 2, a second conveyor belt 3, and a baking lamp 4. The first conveyor belt 2 and the second conveyor belt 3 are both fixedly installed inside the baking oven 1. One end of the first conveyor belt 2 is located outside one end of the second conveyor belt 3, and both are located outside one end of the baking oven 1. The first conveyor belt 2 and the second conveyor belt 3 are used to transport the paper packaging boxes after printing the pattern. The upper ends of the first conveyor belt 2 and the second conveyor belt 3 are both fixedly installed with baking lamps 4. The baking lamps 4 are fixedly installed inside the baking oven 1 and are used to bake the paper packaging boxes.
[0020] At the other end of the baking oven 1, a fixing plate 5 and a fixing plate 6 are fixedly installed on the front and rear sides respectively. Several rotating rollers 9 are evenly fixed between the fixing plate 5 and the fixing plate 6. A fixing block 7 is fixedly installed on the inner end of the fixing plate 5 and the fixing plate 6. A side plate 8 is fixedly installed at the inner end of the fixing block 7 at an angle. The side plate 8 is located at the upper end of the second conveyor belt 3 and on the outer side of the first conveyor belt 2. Several rotating rollers 9 are evenly rotatably connected between the two side plates 8. The rotating rollers 9 are used to transfer the paper packaging boxes on the first conveyor belt 2 to the second conveyor belt 3.
[0021] A flipping component is installed at the inner end of the fixed plate 5. The flipping component is used to flip the paper packaging boxes on the conveyor belt 2. The flipping component includes a linear motor 10. A motor 12 is fixedly installed at the outer end of the moving block 11 of the linear motor 10. When the linear motor 10 is started, it can drive the moving block 11 at its upper end to move the motor 12 inside the fixed plate 5. A rotating plate 13 is fixedly installed on the output shaft of the motor 12. When the motor 12 is started, it can drive the rotating plate 13 to rotate. A clamping plate 18 is fixedly installed on the outer side of one end of the rotating plate 13. The clamping plate 18 is located on the lower side of the outer end of the conveyor belt 2. A straight cylinder 14 is fixedly installed on the outer end of the rotating plate 13. A groove 15 is opened on the outer end of the straight cylinder 14. A threaded rod 16 is rotatably connected inside the straight cylinder 14. A second motor 17 is fixedly installed on the upper end of the straight cylinder 14. The output shaft of the second motor 17 is fixedly connected to one end of the threaded rod 16 through a coupling. The second motor 17 is a servo motor that can drive the threaded rod 16 to rotate in both directions.
[0022] A movable plate 19 is provided at the upper end of the clamping plate 18. A slider 20 is fixedly installed at one end of the movable plate 19. A threaded sleeve 21 is fixedly installed at the outer end of the slider 20. One end of the slider 20 is slidably inserted into the groove 15. The threaded sleeve 21 and the outer wall of the threaded rod 16 are threadedly connected. Anti-slip pads are fixedly installed on the sides of the clamping plate 18 and the movable plate 19 that are close to each other. When the motor 17 drives the threaded rod 16 to rotate, the threaded rod 16 drives the threaded sleeve 21 to move the movable plate 19, thus completing the clamping and releasing of the paper packaging box.
[0023] Specifically, when the paper packaging box is being conveyed on conveyor belt 2, as it is about to leave conveyor belt 2, under the action of inertia, the paper packaging box moves outward and lands on the upper end of clamping plate 18. Then, motor 2 17 is started to drive moving plate 19 to one side of clamping plate 18 to clamp the paper packaging box. Next, linear motor 10 is started to move the paper packaging box to one side of rotating roller 9. Finally, motor 12 is started to drive rotating plate 13 to rotate clamping plate 18, moving plate 19 and paper packaging box to be parallel to rotating roller 9. Motor 2 17 is started again to drive moving plate 19 away from clamping plate 18. Under the action of gravity, the paper packaging box slides off clamping plate 18 and lands on conveyor belt 2 3 under the guidance of rotating roller 9, completing the flipping of the paper packaging box.
[0024] Cleaning components are provided at the lower ends of both conveyor belt 2 and conveyor belt 3. The cleaning components are used to clean the surfaces of conveyor belt 2 and conveyor belt 3. The cleaning components include an operating port 22, a mounting plate 23, a motor 3 24, and a sliding frame 26. The operating port 22 is opened on one side wall of the baking oven 1. The mounting plate 23 is fixed to the outer wall of the baking oven 1 by bolts, and the mounting plate 23 is located outside the operating port 22. The motor 3 24 is fixedly installed at the outer end of the mounting plate 23. The output shaft of the motor 3 24 rotates through the mounting plate 23 and is fixedly installed with a protrusion 25.
[0025] The sliding frame 26 is fixedly installed inside the oven 1. There are two sliding frames 26, which are located below the first conveyor belt 2 and the second conveyor belt 3 respectively. The sliding plate 27 is slidably connected inside the sliding frame 26. The sliding plate 27 is located inside the operating port 22. The sliding plate 27 can enter the sliding frame 26 from the operating port 22. The front and rear ends of the sliding plate 27 are fixedly installed with upright plates 28. The two upright plates 28 are rotatably connected to the rotating drum 29. The end of the rotating drum 29 near the operating port 22 has a docking groove 30. Both the protrusion 25 and the docking groove 30 are hexagonal. When the mounting plate 23 is fixed to the outer end of the oven 1, the protrusion 25 slides into the docking groove 30 and limits the sliding plate 27 inside the sliding frame 26. When the motor 3 24 is started, the rotating drum 29 can be driven to rotate.
[0026] Several ear plates 31 are evenly fixedly installed on the outer end of the rotating drum 29. Cleaning brushes 32 are fixedly installed on the ear plates 31 by bolts. The bristles of the cleaning brushes 32 are in contact with the outer walls of the first conveyor belt 2 and the second conveyor belt 3. When the rotating drum 29 rotates, it drives the cleaning brushes 32 to clean the surfaces of the first conveyor belt 2 and the second conveyor belt 3.
[0027] A dust collection box 33 is fixedly installed on one side of the upper end of the skateboard 27 via a support plate 35. A dust collection pipe 34 is fixedly installed on one end of the dust collection box 33. One end of the dust collection pipe 34 extends out of the mounting plate 23. The outer end of the dust collection pipe 34 is connected to an external vacuum cleaner. When the vacuum cleaner is started, it can absorb the ink dust cleaned by the cleaning brush 32 through the dust collection box 33.
[0028] When this device is in operation, the printed paper packaging boxes are transported to the upper end of conveyor belt 2. Conveyor belt 2 transports and bakes the boxes through baking lamps 4. When the boxes reach the other end of conveyor belt 2, a flipping component flips them over. The flipped boxes fall onto the upper end of roller 9 and then roll onto the upper end of conveyor belt 3. Conveyor belt 3 transports the flipped boxes and bakes them through baking lamps 4, thus completing the transport and drying of the paper packaging boxes. At the same time, a cleaning component is activated to clean the surfaces of conveyor belts 2 and 3, making it easier to remove the ink from the surfaces of conveyor belts 2 and 3 and ensuring the exterior of the packaging boxes is clean.
