[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] Please see Figures 1 to 5This utility model provides a technical solution: a rotary printing device, including a worktable 1, an L-shaped frame 2 fixedly installed at the top of one end of the worktable 1, a printing mechanism 7 installed below the top of the L-shaped frame 2 via a hydraulic rod 5, a turntable 3 installed on the top of the worktable 1 via a drive mechanism, and placement mechanisms 4 symmetrically arranged on both sides of the top of the turntable 3, the placement mechanism 4 including a placement frame 11, a horizontal plate 12 slidably installed inside the placement frame 11, the horizontal plate 12 being a filter plate, an air hole 13 opened at the bottom of the placement frame 11 corresponding to the interior of the turntable 3, a fixing column 8 fixedly installed below the top of the L-shaped frame 2 corresponding to one side of the printing mechanism 7, an inclined surface opened at the bottom of the fixing column 8, one end of the horizontal plate 12 in contact with the inclined surface, hot air inside the turntable 3 can dry the items through the air hole 13 and the horizontal plate 12, thereby improving the drying efficiency of printed patterns, facilitating the subsequent removal of items, and having high practicality.
[0025] In this embodiment, the placement frame 11 is square in shape, and symmetrical grooves are provided inside one end of the placement frame 11. One end of the horizontal plate 12 is located on the outside of the placement frame 11. Slider 21 is fixedly installed on both sides of one end of the horizontal plate 12 at the position corresponding to the groove. The slider 21 is slidably installed inside the groove. A spring 20 is fixedly installed between the bottom of the horizontal plate 12 and the turntable 3. The driving mechanism includes a first servo motor 9, which is fixedly installed on the bottom of the worktable 1. The turntable 3 is fixedly installed on the output shaft of the first servo motor 9. An air inlet pipe 10 is fixedly installed inside the worktable 1 on one side corresponding to the first servo motor 9. The top end of the air inlet pipe 10 is located inside the turntable 3. Through the limiting effect of the slider 21 and the groove, the stability of the horizontal plate 12 can be improved, making it easier for the horizontal plate 12 to slide up and down. Under the elastic force of the spring 20, the horizontal plate 12 lifts the item upward, making it easy to take out the item.
[0026] In this embodiment, a fixed tube 6 is provided above the printing mechanism 7 corresponding to the interior of the L-shaped frame 2. The printing mechanism 7 includes a limiting frame 15. The hydraulic rods 5 are symmetrically fixed inside the top of the L-shaped frame 2. The two ends of the limiting frame 15 are slidably mounted on the outside of the output rod of the hydraulic rod 5. An adjusting plate 14 is fixedly provided at the bottom of the output rod of the hydraulic rod 5. The limiting frame 15 is movably positioned above the adjusting plate 14. Springs 20 are fixedly installed between the two ends of the limiting frame 15 and the adjusting plate 14. A second servo motor 17 is fixedly installed on the outer wall of the top of the limiting frame 15. A screw 18 is fixedly provided on the output shaft of the second servo motor 17. The screw 18 is rotatably mounted inside the top of the limiting frame 15. The outer side of the screw 18 is screwed together. A scraper 19 is provided, which is movably disposed inside a limiting frame 15. The limiting frame 15 and an adjusting plate 14 are snapped together and mounted on a screen printing plate 16. The bottom end of the scraper 19 is in contact with the bottom inner side of the screen printing plate 16. The hydraulic rod 5 can drive the adjusting plate 14, the limiting frame 15, and the screen printing plate 16 to descend and abut against the top of the item. The second servo motor 17 and the screw 18 drive the scraper 19 to move inside the screen printing plate 16, which facilitates the application of ink to the top of the item, thus facilitating printing. The limiting frame 15 can limit the screen printing plate 16 under the tension of the spring 20, which can improve the stability of the screen printing plate 16. The screen printing plate 16 can also be easily replaced by adjusting the limiting frame 15, so as to print different patterns or text.
[0027] When using this rotary printing device, the item to be printed is placed inside the placement frame 11 above the horizontal plate 12. The first servo motor 9 is started, and the first servo motor 9 drives the turntable 3 to rotate on the top of the worktable 1. The turntable 3 drives the item to rotate through the placement mechanism 4, such as the placement frame 11. Through the squeezing action of the fixed column 8, the inclined plane, and the horizontal plate 12, the horizontal plate 12 slides downward inside the placement frame 11 via the slider 21 and the slide groove. The horizontal plate 12 drives the item to move downward and to the bottom of the printing mechanism 7. Printing ink is added to the screen printing plate 16 through the fixed tube 6. The hydraulic rod 5 is started, and the hydraulic rod 5 drives the adjusting plate 14 and the limiting frame 15 to descend. The limiting frame 15 moves upward on the output rod of the hydraulic rod 5, and the limiting frame 15 stretches the spring 20, placing the screen printing plate 16 between the top of the two adjusting plates 14 and the limiting frame 15. The bottom of both ends of the positioning frame 15 is provided with protrusions, while the top of both ends of the screen printing plate 16 is provided with grooves. When the positioning frame 15 is released, it slides downward under the tension of the spring 20 and contacts the top of the screen printing plate 16. The protrusions are engaged inside the grooves to facilitate the positioning of the screen printing plate 16. The adjusting plate 14 drives the screen printing plate 16 to descend and make contact with the top of the item. The second servo motor 17 drives the screw 18 to rotate, and the screw 18 drives the squeegee 19 to move inside the screen printing plate 16 to print on the item. At the same time, hot air is introduced into the turntable 3 through the air inlet pipe 10. The hot air dries the surface of the item through the air hole 13 and the horizontal plate 12. After printing, as the turntable 3 rotates, the horizontal plate 12 can lift the item upward under the elastic force of the spring 20, making it easy to remove the item without scratching the printed pattern, which is highly practical.
