DETAILED DESCRIPTION
[0023] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.
[0024] A screen printing machine for flannel spring couplets, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 As shown, it includes a placing table 1, a driving device 2 installed on the placing table 1 and a scraper 3 installed on the driving device 2, the driving device 2 can control the movement of the scraper 3, the placing table 1 is fixedly connected with an electric slide rail 4, the electric slide rail 4 is slidably connected with a slider 5, the slider 5 is fixedly connected with a positioning frame 6, the positioning frame 6 is slidably connected with a screen printing plate 7 and is provided with a resetting member for resetting the screen printing plate 7, so that the screen printing plate 7 can be moved up and down for easy removal of the printed spring couplets, the positioning frame 6 is provided with slide grooves 8 on both sides, the slide grooves 8 are provided with a scraping member for removing the fluff on the bottom side of the screen printing plate 7, and the positioning frame 6 and the scraper 3 are provided with connecting members that enable the scraping member to be controlled by the driving device 2.
[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6As shown, when printing, first pour ink into the screen printing plate 7, then put the spring couplets between the placement table 1 and the screen printing plate 7, then start the electric slide 4 to drive the positioning frame 6 to move downward until the positioning frame 6 fits with the placement table 1, and then start the drive device 2 to drive the scraper 3 to move downward to press the screen printing plate 7 until the silk screen on the screen printing plate 7 fits with the spring couplets, and then start the drive device 2 to control the scraper 3 to print. After printing is completed, the drive device 2 will drive the scraper 3 to move upward, and at this time the reset member drives the screen printing plate 7 to move upward. The plate 7 is reset, and during the reset, the screen printing plate 7 always remains in contact with the scraper 3 until the reset is completed. After the reset is completed, the electric slide rail 4 is started again to move the positioning frame 6 upward and take out the printed spring festival couplets, and then the drive device 2 is started to control the movement of the scraper 3. At this time, the connecting part will drive the scraper to remove the fluff adhered to the bottom of the screen printing plate 7. In this way, the fluff adhered to the bottom side of the screen printing plate 7 can be scraped off by reciprocating, so as to avoid a large amount of fluff mixing with ink to produce particulate impurities, which will affect the printing quality and cause defective products.
[0026] like Figure 1-Figure 3 As shown, the reset member includes a plurality of fixed blocks 11 fixedly connected to the positioning frame 6 and a sliding rod 12 slidably connected to the fixed block 11, the sliding rod 12 is fixedly connected to the screen printing plate 7, and the sliding rod 12 is between the positioning frame 6 and the screen printing plate 7 and is sleeved with a spring 13. When the screen printing plate 7 is pressed down, the top side of the sliding rod 12 will approach the positioning frame 6 and stretch the spring 13. After printing is completed, the driving device 2 will drive the scraper 3 to move upward. At this time, the top side of the sliding rod 12 will be reset away from the positioning frame 6 due to the spring 13, and drive the screen printing plate 7 to reset and keep in contact with the scraper 3 until the screen printing plate 7 is reset. In this way, the screen printing plate 7 can be reset.
[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 As shown, the scraping member includes a slider 9 slidably connected to the slide groove 8, and a scraper 10 is fixedly connected between the two sliders 9. When the spring 13 is in a normal state, the top side of the scraper 10 and the bottom side of the screen printing plate 7 are arranged on the same horizontal line. If the scraper 10 moves left and right on the slide groove 8 at this time, the scraper 10 passes through the bottom side of the screen printing plate 7, and the fluff on the bottom side of the screen printing plate 7 can be removed.
[0028] like Figure 1 , Figure 3 , Figure 4As shown, the connecting member includes a magnet 14 fixedly connected to the slider 2 9, a positioning rod 15 fixedly connected to the scraper 3, and a magnet 2 16 fixedly connected to the positioning rod 15. When the screen printing plate 7 is pressed down and printing is performed, causing the magnet 14 to contact the magnet 2 16, the magnet 14 will be attracted to the magnet 2 16, but since the scraper 10 will be blocked by the screen printing plate 7 at this time, when the magnet 2 16 is away from the magnet 14, it will only separate from the magnet 14. After the screen printing plate 7 is reset, the scraper 10 will no longer be restricted by the screen printing plate 7. At this time, the driving device 2 drives the scraper 10 to move left and right when the scraper 10 does not contact the screen printing plate 7, causing the magnet 14 to attract the magnet 2 16, and then the scraper 10 can be driven to move on the bottom side of the screen printing plate 7 to scrape off the fluff on the bottom side of the screen printing plate 7.
[0029] like Figure 1 , Figure 3 , Figure 5 As shown, a sliding plate 17 is slidably connected to the scraper 3, and a rejection plate 18 for removing particulate impurities in the ink is provided on the sliding plate 17. The rejection plate 18 will slide on the scraper 3 due to gravity and always adhere to the screen printing plate 7. At this time, the driving device 2 drives the scraper 3 to move left and right to remove the particulate impurities in the ink.
[0030] like Figure 5 As shown, the rejection plate 18 includes a plurality of fixed plates 181 and connecting rods 182 fixedly connected to the plurality of fixed plates 181. There are gaps between the plurality of fixed plates 181, through which ink can pass and particulate impurities can be blocked. The plurality of fixed plates 181 are located on the upper side of the screen printing plate 7 and are in contact with the screen on the screen printing plate 7. When the scraper 3 moves left and right, the plurality of fixed plates 181 will be driven by the sliding plate 17 to move in the ink. When moving, the particulate impurities in the ink can be rejected through the gaps between the fixed plates 181.
[0031] like Figure 2 , Figure 6 As shown, a receiving plate 19 is fixedly connected between the two sliders 9 at the lower side of the scraper 10. When the scraper 10 scrapes the lower side of the screen printing plate 7, the receiving plate 19 can receive the fluff on the scraper 10 to prevent the fluff from falling onto the placement table 1 and causing the spring festival couplets to be contaminated.
[0032] like Figure 4 , Figure 6 As shown, a scraper block 20 is slidably connected between the receiving plate 19 and the scraper 10. When a lot of fluff remains in the receiving plate 19, the scraper block 20 can be moved left and right to conveniently remove the fluff on the receiving plate 19.
[0033] Working principle: When printing, first pour the ink into the screen printing plate 7, then put the spring couplets between the placement table 1 and the screen printing plate 7, then start the electric slide rail 4 to drive the positioning frame 6 to move downward until the positioning frame 6 fits with the placement table 1, and then start the drive device 2 to drive the scraper 3 to move downward to press the screen printing plate 7 until the screen on the screen printing plate 7 fits with the spring couplets. At this time, the spring 13 is in a stretched state, and then start the drive device 2 to control the scraper 3 to print. During printing, several fixed plates 181 will be driven by the sliding plate 17 And move in the ink to remove the particle impurities in the ink. After printing is completed, the driving device 2 will drive the scraper 3 to move upward. At this time, the top side of the sliding rod 12 will be reset away from the positioning frame 6 due to the spring 13. After the reset is completed, the electric slide rail 4 is started again to move the positioning frame 6 upward and take out the printed spring festival couplets, and then the driving device 2 is started to control the movement of the scraper 3. After the magnet 14 and the magnet 2 16 are attracted, the driving device 2 can drive the scraper 10 to move on the bottom side of the screen printing plate 7 to scrape off the fluff on the bottom side of the screen printing plate 7.
[0034] With this method, the fluff adhering to the bottom side of the screen printing plate 7 can be scraped off after each printing to avoid a large amount of fluff mixing with the ink to produce particulate impurities. A reject plate 18 is provided to remove the particulate impurities produced by the screen printing plate 7 after long-term operation to avoid the problem of defective products caused by printing failure.
