[0001] The utility model relates to the field of film printing, and more specifically, to a dust removal device for a film double-sided printing machine. Background Art

[0002] Film printing machine is a kind of equipment that can be widely used in various packaging fields. Generally, ink is transferred to the substrate through the printing plate. In the current printing work, it is often encountered that the substrate needs to be printed on both sides. In order to ensure the printing quality of the film during the printing process, a dust removal device is used to remove dust or hair on the film.

DETAILED DESCRIPTION

[0023] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] A dust removal device for a film double-sided printing machine, such as Figure 1-3As shown, it includes a placing table 1, a winding drum 2 fixedly connected to the placing table 1, a printing mechanism 3 and an unwinding drum 4, the placing table 1 is fixedly connected with a fixing rod 5, and an adhesive drum 1 6 and an adhesive drum 2 7 are rotatably connected to the fixing rod 5. The film is rolled up by the winding drum 2, and the film is allowed to pass between the adhesive drum 1 6 and the adhesive drum 2 7, so that the stubborn dust on the film is removed, the placing table 1 is fixedly connected with a placing frame 1 8 between the fixing rod 5 and the unwinding drum 4, the placing table 1 is fixedly connected with a placing frame 2 9 between the fixing rod 5 and the printing mechanism 3, the placing frame 1 8 and the placing frame 2 9 are provided with a groove 10, and liquid is stored in the groove 10, the placing frame 1 8 and the placing frame 2 9 are slidably connected with a sliding plate 11, and a sponge block 12 is fixedly connected to the sliding plate 11, and the sponge block 12 is in a saturated state of water absorption, and the sponge block 12 is pressed by the sliding plate 11 to fit the adhesive drum 1 6 and the adhesive drum 2 7, so that the adhesive drum 1 6 and the adhesive drum 2 can be attached to each other. The dust on 7 is removed, a cutter 13 is fixedly connected to the placement frame 1 8 and the placement frame 2 9, and two pressing components for cooperating with the cutter 13 to cut the sponge block 12 are provided on the fixed rod 5, and a driving component for driving the sliding plate 11 to slide is provided on the fixed rod 5. After the two sponge blocks 12 are attached to the adhesion tube 1 6 and the adhesion tube 2 7 for a period of time, the cleaning effect will be lost. At this time, the invalid part of the sponge block 12 can be cut off by the cooperation of the pressing component and the cutter 13, and the next working part of the sponge block 12 will be pressed into the groove 10 by the pressing component to absorb water again, and then the sliding plate 11 is driven by the driving component to slide to one side of the fixed frame 22, so that the sponge block 12 fixedly connected to the sliding plate 11 is attached to the adhesion tube 1 6 and the adhesion tube 2 7 again. In this way, the stubborn dust can be effectively cleaned, and the adhesion tube 1 6 and the adhesion tube 2 7 are processed to ensure the stubborn dust cleaning effect and avoid affecting the printing quality.

[0025] like Figure 1-3 As shown, the pressing assembly includes an electric push rod 14 fixedly connected to the fixed rod 5 and a pressure plate 15 fixedly connected to the electric push rod 14. A storage frame 18 is fixedly connected to the bottom side of the placement frame 8. The electric push rod 14 drives the pressure plate 15 to press the sponge block 12 downward. When the pressure plate 15 continues to move downward, it will contact the cutter 13. At this time, the invalid part of the sponge block 12 is cut off, and the cut sponge block 12 is brought into the storage frame 18 because the adhesion tube 6 rotates, thereby completing the cutting work of the invalid part of the sponge block 12, and the cut sponge block 12 is stored to prevent the cut sponge block 12 from falling onto the film.

[0026] like Figure 1-3As shown, the driving assembly includes an electric push rod 2 16 fixedly connected to the fixed rod 5 and a connecting plate 17 fixedly connected to the electric push rod 2 16. The connecting plate 17 is fixedly connected to the sliding plate 11. The connecting plate 17 is driven by the electric push rod 2 16, and then the connecting plate 17 drives the sliding plate 11 to approach the fixed rod 5, so that the sponge block 12 fixedly connected to the sliding plate 11 is again attached to the adhesive tube 1 6 and the adhesive tube 2 7, thereby completing the driving work.

[0027] like Figure 1 , Figure 2 , Figure 4 As shown, both ends of the adhesive cylinder 16 are rotatably connected to the limit blocks 19, and the fixing rod 5 is provided with a groove 20 for the limit blocks 19 to slide. When it is necessary to perform adhesive operations on films of different thicknesses, the adhesive cylinder 16 can be lifted, and then the film can be clamped by the adhesive cylinder 16's own gravity, and it is convenient to pass the film through between the adhesive cylinder 16 and the adhesive cylinder 27 before work.

[0028] like Figure 1 , Figure 2 , Figure 5 As shown, the inner bottom surface of the storage frame 18 is gradually lowered close to the unwinding drum 4, so that the cut sponge block 12 can automatically slide to the bottom of the storage frame 18.

[0029] like Figure 1 , Figure 2 , Figure 5 As shown, a guide tube 21 is fixedly connected to the bottom side of the storage frame 18 to prevent the film from contacting the bottom of the storage frame 18 and being contaminated.

[0030] like Figure 1 As shown, a fixing frame 22 is fixedly connected between the fixing rod 5 and the printing mechanism 3 on the placement table 1, and a plurality of fans 23 are fixedly connected to the fixing frame 22 to dry any water stains on the film.

[0031] like Figure 1 As shown, the output ends of the fans 23 are tilted toward the side close to the fixing rod 5, which can speed up the drying of water stains.

[0032] Working principle: Before printing, the film is passed through between the adhesive cylinder 1 6 and the adhesive cylinder 2 7, and then the fan 23 is turned on and the film is rolled up by the winding cylinder 2. At this time, the winding cylinder 2 will also rotate due to the pumping of the film to adhere to the stubborn dust. At the same time, the two sponge blocks 12 will fit the adhesive cylinder 1 6 and the adhesive cylinder 2 7 to clean the adhesive cylinder 1 6 and the adhesive cylinder 2 7. After the two sponge blocks 12 fit the adhesive cylinder 1 6 and the adhesive cylinder 2 7 for a period of time, the electric push rod 1 14 can drive the pressure plate 15 to squeeze the sponge block 12 downward. When the pressure plate 15 continues to move downward, it will contact the cutter 13. At this time, part of the sponge block 12 is ineffective. The sponge block 12 is cut off immediately, and because the adhesion tube 16 rotates, the cut sponge block 12 is brought into the storage frame 18. At the same time, the next working part of the sponge block 12 will be pressed into the groove 10 by the pressing plate 15 to absorb liquid again, and then the connecting plate 17 is driven by the electric push rod 2 16, and the connecting plate 17 drives the sliding plate 11 to approach the fixed rod 5, so that the sponge block 12 fixedly connected to the sliding plate 11 is again attached to the adhesion tube 1 6 and the adhesion tube 2 7. In this way, the stubborn dust can be effectively cleaned, and the adhesion tube 1 6 and the adhesion tube 2 7 can be processed to ensure the stubborn dust cleaning effect and avoid affecting the printing quality.
