[0002] Digital printing machines are developed on the basis of inkjet printers. They can print different types of printing devices according to different process requirements. Digital printing machines need to apply glue to the printed part before printing to prevent the printing from falling off easily after printing. The gluing device of the digital printing machine applies glue to the gluing drum, and uses a scraper to scrape the glue on the drum and evenly apply the glue on the printed material. Since the glue is in gel form, the amount of glue discharged is not fixed when discharging, which can easily make the amount of glue on the drum surface uncertain, affecting the gluing of the digital printing machine.

[0026] The control assembly includes a driving motor 6, a rotating drum 7 is installed at the side end of the driving motor 6, the rotating drum 7 crosses the glue outlet of the glue box 4, a positioning block 9 is installed at the side end of the rotating drum 7, the positioning block 9 is located on the inner wall of the glue box 4, and a plurality of transverse plates 8 are installed on the outer surface of the rotating drum 7, the plurality of transverse plates 8 are equally spaced around the outer surface of the rotating drum 7, and the plurality of transverse plates 8 are at least not less than three, and the rotating drum 7 is driven to rotate by the output shaft of the driving motor 6 under the action of the positioning block 9, which is fixed in the position and convenient for rotation. , several horizontal plates 8 rotate along the center of the rotating drum 7 on the outer surface of the rotating drum 7. During the rotation process, an equal amount of glue is discharged between two adjacent horizontal plates 8, which facilitates the glue to flow out evenly and be smeared on the surface of the adhesive cylinder 11, avoiding uneven glue discharge affecting the gluing of the printing machine and improving the quality of the finished product. The glue outlet of the glue box 4 is V-shaped, and the plates on both sides of the opening have a certain angle. When the two horizontal plates 8 are vertically placed on the plates on both sides of the glue outlet of the glue box 4 at the same time, it can also prevent the glue from contacting the air and solidifying when not in use.

[0027] Embodiment 2

[0028] Based on the first embodiment, Figure 3 , Figure 2 as well as Figure 5 As shown, this embodiment proposes a technical solution to solve the problem of excess glue on the surface of the glue tube 11;

[0029] Specifically, a scraper 3 is fixedly installed on the inner wall of the gluing machine housing 1, and the scraper 3 is placed in an inclined position. The scraper 3 scrapes the glue on the outer surface of the glue cylinder 11 flat. The inner wall of the gluing machine housing 1 is installed with a fixed sleeve rod 2, and a glue collecting box 13 is installed on the outer surface of the fixed sleeve rod 2. Both ends of the top of the glue collecting box 13 are movably sleeved on the fixed sleeve rod 2, and the bottom of the opening of the glue collecting box 13 is flush with the bottom of the scraper 3. A heating lamp 14 is installed on the top of the inner wall of the glue collecting box 13, and baffles 15 are installed on the outer walls of both ends of the glue collecting box 13. The baffles 15 prevent the bottom of the glue collecting box 13 from tilting toward the inside of the gluing machine housing 1. In order to prevent the glue from solidifying, the heating lamp 14 scrapes the excess glue into the glue collecting box 13, which is convenient for recycling and reuse, saving glue and avoiding waste of resources.

[0030] The inner wall of the glue collecting box 13 is installed with a limit block 16, and a screw rod 18 is installed at the center of the side wall of the limit block 16. The screw rod 18 penetrates the side wall of the glue collecting box 13, and a transmission motor 20 is installed at one end of the screw rod 18. A fixed rod 17 is installed inside the glue collecting box 13, and a square plate 19 is installed around the outer surfaces of the fixed rod 17 and the screw rod 18. A hole groove is opened at the bottom of the glue collecting box 13, and the hole groove is close to the bottom of the transmission motor 20. A rubber plug 21 is installed inside the hole groove. When the glue application device is finished, the glue collecting box 13 is removed from the fixed position. The fixed sleeve rod 2 is removed, and the limit block 16 fixes the screw rod 18 without affecting the rotation of the screw rod 18. The screw rod 18 is driven to rotate by the transmission motor 20. Under the action of the fixed rod 17, the screw rod 18 drives the square plate 19 to move along the screw rod 18 in the glue collection box 13 through the thread. The initial position of the square plate 19 is always the position where the end of the screw rod 18 is close to the limit block 16. When the square plate 19 moves from the initial position to the position close to the transmission motor 20, the glue is pushed to the hole groove of the glue collection box 13, and the rubber plug 21 is opened to discharge the glue and recover it into the glue loading box 4.

[0031] Embodiment 3

[0032] like Figure 2 As shown, a rotating rod 12 is installed through the inner wall of the gluing machine housing 1, and a power motor 10 is installed at one end of the rotating rod 12. The power motor 10 is located on the side wall of the gluing machine housing 1. A glue cylinder 11 is installed around the outer surface of the rotating rod 12. The glue cylinder 11 is located at the center just below the bottom of the glue outlet of the glue box 4. The scraping opening of the scraper 3 is located at the center side of the glue cylinder 11 and has a fixed distance from the glue cylinder 11. The power motor 10 drives the rotating rod 12 to rotate, and the rotating rod 12 drives the glue cylinder 11 to evenly stick the glue on the outer surface, and the glue is applied to the printed material;

[0033] A hole is provided at the top center of the glue box 4, and a sealing cover 5 is installed inside the hole. The hole is convenient for filling glue, and the sealing cover 5 prevents the glue from flowing out and solidifying.

[0034] Working principle: When in use, the output shaft of the driving motor 6 drives the rotating drum 7 to rotate, and a plurality of horizontal plates 8 rotate on the outer surface of the rotating drum 7 along the center of the rotating drum 7. During the rotation process, an equal amount of glue is discharged between two adjacent horizontal plates 8, so that the glue flows out evenly and is applied to the surface of the adhesive cylinder 11, avoiding uneven glue discharge affecting the gluing of the printing machine and improving the quality of the finished product. When the two horizontal plates 8 are vertically mounted on both sides of the glue outlet of the glue box 4 at the same time, the glue can be prevented from solidifying due to contact with air when not in use. The power motor 10 drives the rotating rod 12 to rotate, and the rotating rod 12 drives the adhesive cylinder 11 to evenly stick the glue to the outer surface. When the adhesive cylinder 11 rotates, the scraper 3 scrapes the glue on the outer surface of the adhesive cylinder 11 and applies the glue on the printed material. The transmission motor 20 drives the screw rod 18 to rotate. Under the action of the fixed rod 17, the screw rod 18 drives the square plate 19 to move along the screw rod 18 in the glue collection box 13 through the thread. The initial position of the square plate 19 is always the position where the end of the screw rod 18 is close to the limit block 16. When the square plate 19 moves from the initial position to the position close to the transmission motor 20, the glue is pushed to the hole groove of the glue collection box 13, and the rubber plug 21 is opened to discharge the glue and recover it to the glue loading box 4. The glue is recycled and utilized while saving material resource costs.
