[0002] When cosmetics are produced, a screen printing machine is required to print patterns, texts, etc. on the bottle. The printing machine is mainly composed of ink, screen, scraper and ink return knife for printing. The scraper and ink return knife move back and forth. The scraper drives the ink accumulated in one place to move, so that the ink is printed on the bottle through the screen. The ink return knife scrapes the ink back to its original position so that the scraper can push the ink again to achieve printing.
[0003] Existing screen printing machines are limited by screen plates, ink scrapers and ink return knives and can only complete single-color screen printing. If two-color printing is required, it needs to be printed twice, and it needs to be dried quickly after each printing to ensure that the ink adheres firmly to the bottle. However, two-color printing requires drying twice, and the dried ink will be heated due to the second drying, which can easily cause the ink in the printed area to turn yellow and affect the printing quality. Therefore, an anti-yellowing screen printing machine is proposed. Utility Model Content

DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this technical field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-6 The anti-yellowing silk-screen printing machine of this embodiment comprises a frame 1 and two groups of suspensions 3, a partition bar 2 is fixedly connected to the middle of the frame 1, a first screen 5 and a second screen 6 are respectively installed between the two sides of the partition bar 2 and the inner wall of the frame 1, a moving platform 4 is installed on the bottom surface of the suspension 3, and two support bars 8 are driven on the moving platform 4 and are respectively located above the first screen 5 and the second screen 6, two groups of telescopic rods 9 are installed on the support bars 8, and a scraper 10 and an ink return knife 11 are respectively fixedly installed at the lower ends of the two groups of telescopic rods 9, and an adjusting unit 7 for controlling the up and down movement of the scraper 10 and the ink return knife 11 is installed on the inner walls of both sides of the lower end of each group of suspensions 3.
[0026] like Figure 1 , 3As shown in Figures 4 and 5, the structure of the screen printing machine in the present invention is similar to that of the existing screen printing machine. The main improvement of the present invention is that it can perform rapid two-color printing, reduce drying time, and prevent the ink from yellowing. When the two-color cosmetic body needs to be printed with screen, the suspension 3 supports the motion platform 4, and different inks are added to the first screen 5 and the second screen 6. The motion platform 4 drives the two support bars 8 to move, and the support bars 8 drive the scraper 10 and the ink return knife 11 to move through the telescopic rod 9. The two scrapers 10 scrape the ink in the first screen 5 and the second screen 6 onto the bottle body for printing, and the two ink return knives 11 scrape the ink in the first screen 5 and the second screen 6 to return to their positions, and the bottle body is printed under the frame 1. There is no need to dry the ink, print it again, and then dry it again. The two-color ink on the bottle body is printed in one place, and the yellow edge of the ink can be avoided by using a single drying method.
[0027] As shown in the figure, the adjustment unit 7 includes two fixed bars 71 respectively installed on the inner walls of both sides of the lower end of the suspension 3, the two ends of the ink scraper 10 and the ink return knife 11 are fixedly connected with sliding rods 72, the side walls of the fixed bar 71 are provided with two sliding grooves 73, and the sliding grooves 73 are fixedly connected with blocking bars 75, the blocking bars 75 are parallelogram structures, the sliding bars 72 at both ends of the ink scraper 10 and the ink return knife 11 are respectively slidably connected with the inner walls of the two sliding grooves 73, the blocking bars 75 in the two sliding grooves 73 are symmetrically distributed, and the two ends of the blocking bars 75 are rotatably connected with inclined plates 76, and the upper surface of the inclined plate 76 is embedded with an elastic sheet 74, and the other end of the elastic sheet 74 is embedded in the inclined surface of the blocking bar 75; when the support bar 8 drives the ink scraper 10 and the ink return knife 11 to move through the telescopic rod 9, the ink scraper 1 The sliding rods 72 at both ends of the chute 73 slide in the two sliding grooves 73 respectively. When the sliding rod 72 slides to one end of the chute 73, the inclined plate 76 is pushed up. After sliding over the inclined plate 76, the inclined plate 76 is returned to its original position under the elastic force of the elastic sheet 74. At this time, when the sliding rod 72 moves back, the inclined plate 76 is blocked, which makes the sliding rod 72 move to the chute 73 on the other side of the baffle 75 and continue to slide, thereby realizing the up and down movement of the ink scraper 10 and the ink return knife 11. When the ink scraper 10 and the ink return knife 11 move up and down, the telescopic rod 9 is telescoped, so that when the ink scraper 10 scrapes the ink, the ink return knife 11 moves up, and vice versa. The structure is used to realize the up and down movement of the ink scraper 10 and the ink return knife 11, without the need to install a driving device, reducing manufacturing costs and improving practicality.
[0028] like Figure 3As shown, the ink scraper 10 and the ink return knife 11 on the first screen 5 and the second screen 6 are in opposite positions, and the sliding rods 72 at both ends of the ink scraper 10 above the first screen 5 and the sliding rods 72 at both ends of the ink return knife 11 above the second screen 6 slide with the sliding grooves 73 under the side walls of the two fixed strips 71 respectively; when the ink scraper 10 above the first screen 5 is scraping ink, the ink return knife 11 above the second screen 6 is returning ink, and the first screen 5 and the second screen 6 stagger the time for inking the bottle body, so as to efficiently ink the bottle body.
[0029] like Figure 2 As shown, a mounting groove 12 is provided on the side wall of the lower end of the suspension 3, and a threaded rod 13 is fixedly connected to the outer wall of the fixing strip 71. The threaded rod 13 passes through the mounting groove 12 and is threadedly connected to a nut 14. The fixing strip 71 is fixed by screwing the nut 14 on the threaded rod 13 passing through the mounting groove 12. The height of the fixing strip 71 is adjustable, so that the height of the scraper 10 and the ink return knife 11 can be adjusted to meet different printing requirements and improve adaptability.
[0030] like Figure 2 As shown, the lower end of the mounting groove 12 is an externally open structure; the threaded rod 13 can slide out along the mounting groove 12, so that the fixing strip 71 can be removed for easy replacement and maintenance.
[0031] like Figure 5 As shown, the thickest part of the baffle 75 is not less than 10 cm; the thickness of the baffle 75 determines the rising height of the ink scraper 10 and the ink return knife 11, so that the ink scraper 10 and the ink return knife 11 have a sufficient rising height to facilitate adding sufficient ink to the first screen 5 and the second screen 6.
[0032] like Figure 1 , 2 As shown, each group of suspensions 3 has two suspensions 3 , and the two suspensions 3 support both ends of the fixing bar 71 through threaded rods 13 and nuts 14 ; the two suspensions 3 suspend both ends of the fixing bar 71 , and the suspension is stable.
[0033] Implementation steps in this embodiment: when it is necessary to print silk screen on the two-color cosmetic body, the suspension 3 supports the motion platform 4, and by adding different inks into the first screen 5 and the second screen 6, the motion platform 4 drives the two support bars 8 to move, and the support bar 8 drives the ink scraper 10 and the ink return knife 11 to move through the telescopic rod 9, and the slide bars 72 at both ends of the ink scraper 10 and the ink return knife 11 slide in the two slide grooves 73 respectively. When the slide bar 72 slides to one end of the slide groove 73, the inclined plate 76 is pushed up, and after sliding over the inclined plate 76, the inclined plate 76 is returned to its position under the elastic force of the elastic sheet 74. At this time, when the slide bar 72 moves back, it is blocked by the inclined plate 76, which causes the slide bar 72 to move to the slide groove 73 on the other side of the blocking bar 75 and continue to slide. The scraper 10 and the ink return knife 11 are moved up and down. When the scraper 10 and the ink return knife 11 move up and down, the telescopic rod 9 is extended and retracted, so that when the scraper 10 scrapes the ink, the ink return knife 11 moves up, and vice versa. The structure is used to realize the up and down movement of the scraper 10 and the ink return knife 11. The two scrapers 10 scrape the ink in the first screen 5 and the second screen 6 onto the bottle body for printing. The two ink return knives 11 scrape the ink in the first screen 5 and the second screen 6 to return to their positions. The bottle body is printed under the frame 1 without drying the ink, printing again, and then drying again. The two-color ink on the bottle body is printed in one place, and the single drying method can avoid yellowing of the ink.
[0034] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
