[0002] Silk screen printing machines are widely used in printing products such as textiles, metal plates, plastics, leather, luggage and ceramics. The silk screen printing machine first makes the text and image to be printed into a printing plate, installs it on the printing machine, and then applies ink to the places with text and images on the printing plate. The text and image are transferred to the workpiece through a scraper, thereby replicating a printed product identical to the printing plate.
[0003] Currently, the commonly used screen printing machines adopt a single-platform structure, which will cause the following problems during use: (1) Due to the limitation of the single platform, after printing, the machine needs to be stopped to replace the material, which wastes time; (2) The ink return knife and scraper often cause damage to the printing plate by squeezing the printing plate, and when different patterns need to be printed, the printing plate also needs to be replaced. However, the printing plate is directly installed on the printing machine, which makes replacement cumbersome. Summary of the invention

[0018] Reference Figure 1-5 A dual-platform screen printing device includes a main board 1, a first servo motor 101 is fixedly connected to the bottom of the main board 1, and a first rotating shaft 102 is fixedly connected to the end of the first servo motor 101 located at the top of the main board 1, and further includes: The side walls on both sides of the first rotating shaft 102 are fixedly connected to the connecting plates 2, the side walls of the connecting plates 2 are fixedly connected to the printing platform 201, the first fixing frames 202 are fixedly connected to the two sides of the surface of the printing platform 201, the top of the first fixing frame 202 is rotatably connected to the rotating column 203, the bottom of the internal rotating column 203 of the first fixing frame 202 is fixedly connected to the first fixing plate 204, and the first spring 205 is fixedly connected between the first fixing plate 204 and the first fixing frame 202; The top of the rotating column 203 is fixedly connected to the limiting plate 206, the top of the first fixing frame 202 is fixedly connected to the limiting column 207, and the limiting plate 206 can be overlapped on the top of the limiting column 207; It should be noted that: when the first servo motor 101 is turned on, the first servo motor 101 will drive the first rotating shaft 102 to rotate. During the rotation process, the first rotating shaft 102 will drive the printing platform 201 to rotate through the connecting plate 2, and the printing platform 201 will be rotated to the bottom of the screen printing plate 309 for printing. At this time, the material of another printing platform 201 can be replaced, that is, the rotating column 203 is lifted upward, and the rotating column 203 will drive the first fixed plate 204 to move upward. At this time, the first spring 205 will be squeezed to generate a rebound force, and then the limit plate 204 at the top of the rotating column 203 is rotated. 06, overlap the limit plate 206 on the top of the limit column 207, and then replace the material on the printing platform 201. After the replacement is completed, rotate the limit plate 206 to move it away from the limit column 207. At this time, there is no limiting effect of the limit column 207, and then under the elastic force of the first spring 205, the rotating column 203 and the first fixed plate 204 are pressed down to fix the material on the printing platform 201, and drive the first rotating shaft 102 to rotate, and rotate it to the screen printing plate 309 for printing. The above can make the device continue to print without stopping the equipment to replace the material, thereby speeding up the work efficiency.
[0019] Reference Figure 1-5 The side wall of the main board 1 is fixedly connected with a sliding frame 3, the inner wall of the sliding frame 3 is slidably connected with a mounting plate 301, and the side wall of the mounting plate 301 is fixedly connected with a second servo motor 302; The second servo motor 302 is fixedly connected to the second rotating shaft 303 at the end thereof, the outer wall screw of the second rotating shaft 303 is connected to the sliding block 304, the top of the sliding block 304 is fixedly connected to two telescopic motors 305, and the bottom of the telescopic motor 305 is respectively fixedly connected to an ink return knife 306 and a scraper 307; The bottom of the mounting plate 301 is fixedly connected with an elastic component, the bottom of the elastic component is fixedly connected with a second fixing frame 308, the inner cavity of the second fixing frame 308 is clamped with a screen printing plate 309, and the screen printing plate 309 is located on the top of the first fixing frame 202; It should be noted that: the telescopic motor 305 is driven so that the ink return knife 306 and the scraper 307 at the bottom of the telescopic motor 305 contact the screen printing plate 309 in turn, and through the driving force of the telescopic motor 305, the elastic component is squeezed to move the screen printing plate 309 downward to the material on the top of the printing platform 201, so that the screen printing plate 309 contacts the material, and then the second servo motor 302 is driven to drive the second rotating shaft 303 to rotate. Since the second rotating shaft 303 and the sliding block 304 are connected by a screw rod, the sliding block 304 will slide on the outer wall of the second rotating shaft 303 when the second rotating shaft 303 rotates, and at the same time drive the ink return knife 306 and the scraper 307 to slide on the screen printing plate 309, thereby completing printing.
[0020] Reference Figure 1-5The elastic component includes a sleeve 4, a sliding column 401 and a second spring 402. The sleeve 4 is fixedly mounted on the bottom of the mounting plate 301. The inner wall of the sleeve 4 is slidably connected with the sliding column 401. The sliding column 401 is fixedly connected to the second fixing frame 308. The second spring 402 is fixedly connected between the sliding column 401 and the sleeve 4. The top of the second fixing frame 308 is threadedly connected with a threaded bolt 403, and the bottom end of the internal threaded bolt 403 located in the second fixing frame 308 is rotatably connected with a second fixing plate 404; An L-shaped plate 405 is clamped between the second fixing plate 404 and the second fixing frame 308. The L-shaped plate 405 is fixedly connected to the screen printing plate 309, and the screen printing plate 309 is located at the bottom of the ink return knife 306 and the scraper 307; It should be noted that: when the elastic component is triggered, the sliding column 401 will drive the screen printing plate 309 fixed inside the second fixing frame 308 to slide down together, so that the second spring 402 is stretched to generate a rebound force. After printing is completed, the ink return knife 306 and the scraper 307 are driven upward by the telescopic motor 305, and the screen printing plate 309 is no longer subjected to pressure. Therefore, under the action of the rebound force of the second spring 402, it returns to its original position, that is, one printing is completed, and the threaded bolt 403 can be rotated in the reverse direction, so that the threaded bolt 403 drives the second fixing plate 404 to move up, thereby releasing the fixed state of the second fixing frame 308 and the screen printing plate 309, and replacing the screen printing plate 309, which is convenient for replacing the printing pattern.
[0021] Operation method: Turn on the first servo motor 101, the first servo motor 101 will drive the first rotating shaft 102 to rotate, and the first rotating shaft 102 will drive the printing platform 201 to rotate through the connecting plate 2 during the rotation, and rotate the printing platform 201 to the bottom of the screen printing plate 309 for printing. When printing, drive the telescopic motor 305, so that the ink return knife 306 and the scraper 307 at the bottom of the telescopic motor 305 contact the screen printing plate 309 in turn, and the driving force of the telescopic motor 305 , squeeze the elastic component to move the screen printing plate 309 downward to the material on the top of the printing platform 201, so that the screen printing plate 309 contacts the material, and then drive the second servo motor 302 to drive the second rotating shaft 303 to rotate. Since the second rotating shaft 303 and the sliding block 304 are connected by a screw rod, when the second rotating shaft 303 rotates, the sliding block 304 will slide on the outer wall of the second rotating shaft 303, and at the same time drive the ink return knife 306 and the scraper 307 to slide on the screen printing plate 309, thereby completing printing; When one printing platform 201 is printing, the material on the other printing platform 201 can be replaced, that is, the rotating column 203 is lifted upward, and the rotating column 203 will drive the first fixed plate 204 to move upward. At this time, the first spring 205 will be squeezed to generate a rebound force, and then the limit plate 206 on the top of the rotating column 203 is rotated, and the limit plate 206 is overlapped on the top of the limit column 207, and then the material on the printing platform 201 is replaced. After the replacement is completed, the limit plate 206 is rotated to keep it away from the limit column 207. At this time, there is no restriction effect of the limit column 207, and the first spring 205 is released. Under the elastic force of the spring 205, the rotating column 203 and the first fixed plate 204 are pressed down to fix the material on the printing platform 201, and the first rotating shaft 102 is driven to rotate and rotate it to the screen printing plate 309 for printing. The above can make the device continue to print without stopping the equipment to replace the material, thereby speeding up the work efficiency. The threaded bolt 403 can be rotated in the reverse direction so that the threaded bolt 403 drives the second fixed plate 404 to move up, release the fixed state of the second fixing frame 308 and the screen printing plate 309, and replace the screen printing plate 309 to facilitate the replacement of the printing pattern.
