[0002] A printing machine is a device used to transfer text, images or other designs onto paper, fabric, plastic or other materials. The most common printing machine technology is lithography, where the image part and the non-image part are distinguished through chemical treatment. Ink only adheres to the image area, and then the image is transferred to a rubber blanket and then from the rubber blanket to paper or other materials. During the use of existing printing machines, it is difficult to manually control the ink volume.

[0018] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes, but the protection scope and application scope of the present utility model are not limited.

[0019] Embodiment 1

[0020] An ink volume adjustment device for a printing machine, as Figure 1 and Figure 2 shown, includes a feeder 1. The feeder 1 includes a feed hopper 101, a door panel 102 and a mounting frame 103. A mounting frame 103 is installed on the front side of the feed hopper 101. A door panel 102 is rotatably connected to the upper part of the feed hopper 101. A booster plate is installed on the door panel 102. A rubber pad 2 is installed on the upper part of the feed hopper 101. The rubber pad 2 is used for buffering and protecting the door panel 102. An extension plate 3 for preventing accidental spillage of powder is installed in the feed hopper 101. A material conveying assembly 4 and a transfer assembly 5 are respectively installed in the mounting frame 103. The material conveying assembly 4 is used for conveying the powder that needs to be used, and the rotating assembly is used for adsorbing and using the conveyed powder. An adjustment mechanism 6 for controlling the powder feeding amount is installed in the feed hopper 101.

[0021] As Figures 2 - 4 shown, the material conveying assembly 4 includes a drive assembly 41. A drive assembly 41 is installed in the front part of the feed hopper 101. A developing roller 42 is installed on the output shaft of the drive assembly 41. The developing roller 42 is used for conveying the conveyed powder. A sponge roller 44 is rotatably connected to the right part of the feed hopper 101. The sponge roller 44 is used for flexibly adsorbing the excess powder. A first gear 43 is connected to the front side of the developing roller 42, and a second gear 45 is connected to the front side of the sponge roller 44. The first gear 43 and the second gear 45 are meshed with each other.

[0022] As Figures 1 - 3As shown, the transfer component 5 includes a servo motor 51. A servo motor 51 is installed at the front part inside the feed hopper 101. The servo motor 51 is located on the left side of the driving component 41. A drum 52 is connected to the output shaft of the servo motor 51. The drum 52 is used to adsorb and use the powder. A charging roller 53 is rotatably connected to the left part inside the feed hopper 101. The charging roller 53 is used to generate adsorption ions. The charging roller 53 is located above the drum 52.

[0023] As Figure 2 and Figure 3 As shown, the adjusting mechanism 6 includes an electric push rod 61. Three electric push rods 61 are installed in the middle part inside the feed hopper 101. An adjusting plate 63 for controlling the material discharge amount is connected to the telescopic end of the electric push rod 61. The adjusting plate 63 is of a folded angle structure. Two guiding members 62 are connected to the right part of the adjusting plate 63. The guiding members 62 are slidably connected to the feed hopper 101.

[0024] It should be noted that this device can be installed on a printing machine. When powder replenishment is required, the powder material is put into the feed hopper 101, and then the adjusting mechanism 6 is controlled to operate as needed. The position of the adjusting plate 63 is controlled by the telescopic end of the electric push rod 61, so as to control the powder discharge amount. The powder will move downward under the guidance of the adjusting plate 63 and thus fall on the conveying component. At this time, the driving component 41 is started. The rotation of the output shaft of the driving component 41 will drive the developing roller 42 to rotate, so as to adhere to and drive the powder, making the powder move to the right and approach the drum 52. At the same time, the servo motor 51 and the charging roller 53 need to be started at this time. After the charging roller 53 operates, adsorption ions are generated. The adsorption ions act on the drum 52, enabling the drum 52 to adsorb and use the powder conveyed by the developing roller 42, so that the printing machine can work normally. In this process, it is difficult for the drum 52 to utilize all the powder. Under the continuous rotation of the developing roller 42, the powder will be driven to the right. At this time, due to the continuous rotation of the developing roller 42, the first gear 43 will drive the second gear 45 to rotate, so that the sponge roller 44 and the developing roller 42 rotate in opposite directions, and thus scrape off the powder on the developing roller 42 that has not been adsorbed and used, preventing the powder from sticking to the developing roller 42 all the time and affecting the use. At the same time, the flexible material of the sponge roller 44 can also prevent the developing roller 42 from being damaged, greatly improving the service life of the developing roller 42.

[0025] Embodiment 2

[0026] On the basis of Embodiment 1, as Figure 3 and Figure 4As shown in the figure, it further includes a recycling mechanism 7. The recycling mechanism 7 includes a drawer 71. The drawer 71 is slidably connected to the right part inside the feed hopper 101. A baffle plate 72 is installed in the right part inside the feed hopper 101. The baffle plate 72 is located above the drawer 71. The baffle plate 72 is used to prevent the collected powder from flying out. Two symmetrically arranged limiting members 73 are rotatably connected to the lower right side of the feed hopper 101. The limiting members 73 are used to block and limit the drawer 71.

[0027] It should be noted that the excess powder adhered to the developing roller 42 will be scraped and cleaned by the sponge roller 44 and fall into the drawer 71. When a certain amount of powder accumulates in the drawer 71, the limiting member 73 can be rotated 90 degrees so that the drawer 71 is no longer locked. Then the drawer 71 can be pulled out to recycle the accumulated powder and avoid powder waste.

[0028] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present invention.
