DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1-4The utility model provides an embodiment: a screen printing machine for continuous printing, comprising a supporting fixed frame 1, a screen brush plate 2, a PLC controller 3 and an ink cartridge 11, the screen brush plate 2 is fixedly installed on the top of the supporting fixed frame 1, and the ink cartridge 11 is located directly above the screen brush plate 2. The top of the supporting fixed frame 1 is symmetrically fixedly connected with two top support frames 4, a servo motor 5 is fixedly installed on the middle top of one of the top support frames 4, and a power rod 6 is fixedly connected to the driving end of the servo motor 5. Two sliding rods 7 are symmetrically fixedly installed between the two top support frames 4, a sliding plate 9 is slidably connected to the sliding rod 7, and a linkage rod 8 is rotatably connected to the top of the sliding plate 9, and one end of the power rod 6 away from the servo motor 5 and the other end of the linkage rod 8 away from the sliding plate 9 are rotatably connected, the driving end of the servo motor 5 drives the power rod 6 to rotate, the rotation of the power rod 6 drives the linkage rod 8 to move, and the movement of the linkage rod 8 drives the sliding plate 9 to slide on the sliding rod 7, and two electric push rods 10 are symmetrically fixedly installed on the sliding plate 9.
[0021] Two lifting brackets 13 are symmetrically fixedly connected to the outside of the ink cartridge 11, a box cover 12 is provided at the top of the ink cartridge 11, an anti-overflow ink cartridge 14 is fixedly installed at the bottom of the ink cartridge 11, an ink feed roller 15 is rotatably connected to the middle of the bottom end of the ink cartridge 11, and an annular ink scraper strip 16 is fixedly connected to the bottom end of the inner side of the anti-overflow ink cartridge 14. The annular ink scraper strip 16 is made of rubber, and the inner side of the annular ink scraper strip 16 is designed to be tilted downward. The excess ink is scraped away by the annular ink scraper strip 16 so that it is stored inside the anti-overflow ink cartridge 14 to prevent overflow.
[0022] The PLC controller 3 is fixedly installed on the outer side of the supporting fixed frame 1. The PLC controller 3 is electrically connected to the servo motor 5 and the electric push rod 10 by wires. By setting a program through the PLC controller 3, the servo motor 5 and the electric push rod 10 can be controlled to start and run, thereby realizing continuous printing work.
[0023] The telescopic end of the electric push rod 10 is fixedly connected to the middle of the top of the lifting bracket 13. The electric push rod 10 can be extended by the PLC controller 3 to drive the ink cartridge 11 to move downward. When the bottom ends of the ink feed roller 15 and the anti-overflow ink cartridge 14 are close to the top of the screen brush plate 2, the PLC controller 3 controls the electric push rod 10 to stop extending.
[0024] An ink outlet is provided at the bottom end of the ink cartridge 11, and the top end of the ink feed roller 15 is located on the inner side of the ink outlet of the ink cartridge 11, and the bottom ends of the annular ink scraper strip 16, the ink feed roller 15 and the anti-overflow ink cartridge 14 are level, and when the ink feed roller 15 and the top end of the screen brush plate 2 are tightly attached and the ink feed roller 15 is driven to translate by the ink cartridge 11, the ink feed roller 15 rolls under the action of friction, and the rolling ink feed roller 15 adheres and brings out the ink inside the ink cartridge 11 and evenly coats it on the top end of the screen brush plate 2.
[0025] Working principle: During use, first set the control program through the PLC controller 3. Then, install the silk screen printing plate 2 with the required pattern on the support and fixing frame 1. Then, open the box cover 12 by an external force. Then, load the printing ink into the ink cartridge 11. Then, rotate the ink feeding roller 15 by an external force until the outer surface of the ink feeding roller 15 is evenly adhered with ink. Then, printing can be carried out. When the item to be printed moves to the bottom end of the silk screen printing plate 2 at the start of printing, the PLC controller 3 controls the electric push rod 10 to extend. The telescopic end of the electric push rod 10 drives the lifting bracket 13 to move downward. The movement of the lifting bracket 13 drives the ink cartridge 11 to move downward, thereby driving the overflow prevention ink cartridge 14 and the ink feeding roller 15 to move downward until the bottom ends of the overflow prevention ink cartridge 14 and the ink feeding roller 15 are closely attached to the top end of the silk screen printing plate 2. At the same time, the PLC controller 3 controls the servo motor 5 to start. The driving end of the servo motor 5 drives the power rod 6 to rotate. The rotation of the power rod 6 drives the linkage rod 8 to move. The movement of the linkage rod 8 drives the sliding plate 9 to slide on the slide rod 7. The movement of the sliding plate 9 drives the electric push rod 10 to move, thereby driving the ink cartridge 11 to move. The movement of the ink cartridge 11 drives the ink feeding roller 15 to move. Under the action of friction, the ink feeding roller 15 rolls on the top end of the silk screen printing plate 2. During the rolling process of the ink feeding roller 15, the ink inside the ink cartridge 11 is continuously adhered and coated on the top end of the silk screen printing plate 2. The movement of the ink cartridge 11 drives the overflow prevention ink cartridge 14 to move. The movement of the overflow prevention ink cartridge 14 drives the annular ink scraping strip 16 to move. The movement of the annular ink scraping strip 16 scrapes the ink on the top end of the silk screen printing plate 2, and at the same time transfers the ink in the pattern area to the top end of the item to be printed. Moreover, the annular ink scraping strip 16 collects the excess ink inside the overflow prevention ink cartridge 14. Since the annular ink scraping strip 16 is fixedly connected to the inner bottom end of the overflow prevention ink cartridge 14, the collected ink is stored inside the overflow prevention ink cartridge 14 to prevent spillage. When the driving end of the servo motor 5 rotates to half, the power rod 6 rotates 180 degrees as Figure 2 shown. At this time, the PLC controller 3 controls the servo motor 5 to pause and then continue to rotate. The pause time is determined according to the replacement speed of the item to be printed.
[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
