Technical Field
[0001] This utility model relates to the field of steel drum inkjet printing technology, specifically to a steel drum inkjet printing mechanism with a drum rotation function. Background Technology
[0002] Currently, various types of containers require coding and labeling. However, most existing technologies rely on manual labor for coding and labeling, resulting in extremely low efficiency, high time and labor costs, and reduced overall productivity. Furthermore, most labeling or coding machines on the market operate separately, leading to cumbersome workflows.
[0003] For example, CN222329316U discloses a rotary inkjet printing device for finished product barrels, including a conveyor table and a conveyor belt. The conveyor belt is installed inside the conveyor table, and a rotating device and an inkjet printing device are arranged on the conveyor table. This rotary inkjet printing device places the finished product barrels between two sets of rotating devices. Then, a rotary motor is started, driving a rotating shaft to rotate inside a rotating bearing, which in turn drives the rollers on the outer surface of the rotating shaft to rotate, thus causing the finished product barrels to rotate. This achieves continuous feeding, transport, and inkjet printing of the finished product barrels, improving inkjet printing efficiency. The ink inside the ink cartridge is sprayed onto the outer wall of the finished product barrel through the inkjet printhead. After inkjet printing, the finished product barrel continues to rotate. A dryer is started, and hot air is blown through an air duct to the drying hood and then to the inkjet printing area to quickly dry the ink and prevent ink dripping, which would cause blurry printing.
[0004] However, existing steel drum coding equipment struggles to achieve stable rotation of the steel drums, leading to uneven coding and positional deviations, which affect coding quality. Furthermore, poor connection between the conveying and rotating mechanisms can cause jamming or positional shifts during steel drum transfer, reducing coding efficiency and increasing production risks. Therefore, those skilled in the art provide a steel drum coding mechanism with a rotating function to solve the problems mentioned in the background. Utility Model Content

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] Please see Figures 1-4As shown, this utility model provides a technical solution: a steel drum inkjet coding mechanism with a rotating drum function, including a base plate 1 for supporting the upper part, a conveyor belt 2 for conveying steel drums fixedly connected to the top of the base plate 1, a rotating mechanism 3 for providing rotational power during the inkjet coding process of the steel drums is provided on the side of the conveyor belt 2 near the discharge end, a pushing mechanism 4 for pushing the steel drums to the rotating mechanism 3 is provided on one side of the upper end of the base plate 1, the conveyor belt 2 is horizontally arranged from the feeding end to the discharge end, and the pushing mechanism 4 and the rotating mechanism 3 are on the same horizontal plane in the vertical direction of the conveyor belt 2, an inkjet coding machine body 5 for inkjet coding the rotating steel drums is fixedly connected to the side of the conveyor belt 2 near the discharge end, the inkjet coding machine body 5 is located directly above the rotating mechanism 3, and a drum body 6 to be inkjet coded is provided at the upper end of the conveyor belt 2.
[0022] The horizontally positioned conveyor belt 2 ensures the steel drum maintains a stable posture during transport, preventing swaying or positional shifts caused by tilted transport, thus providing a precise positional foundation for subsequent coding processes. The pushing mechanism 4 and rotating mechanism 3 are on the same horizontal plane in the vertical direction of the conveyor belt 2, ensuring a seamless connection in height when the steel drum is pushed from the conveyor belt 2 to the rotating mechanism 3. This prevents the drum from bouncing or falling due to height differences, ensuring a smooth transfer process. The rotating mechanism 3 provides continuous and stable rotational power for coding the steel drum, enabling the coding machine 5 to perform omnidirectional and uniform coding on the rotating drum. This effectively avoids problems such as incomplete coding and positional deviations that may occur during static coding. Furthermore, the coding machine 5, positioned directly above the rotating mechanism 3, can precisely align with the coding area on the steel drum, further improving coding accuracy. The overall structure features clearly defined functions and close cooperation among its components, achieving stable transport, precise pushing, and reliable rotation of the steel drum while ensuring consistent and accurate coding quality, significantly improving the efficiency and automation level of steel drum coding operations.
[0023] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, the rotating mechanism 3 includes a motor 31, which is fixedly connected to the side of the conveyor belt 2 near the discharge end. A rotating shaft 32 is rotatably connected to the center of the bottom end of the motor 31, and two sets of synchronous belts 33 are provided on the outer surface of the rotating shaft 32.
[0024] When the steel drum is conveyed to a position near the discharge end, the motor 31 starts, and the rotating shaft 32 at the center of the bottom end of the motor 31 begins to rotate. Since two sets of synchronous belts 33 are provided on the outer surface of the rotating shaft 32, the rotational motion of the rotating shaft 32 is transmitted to the movable shaft 34 rotatably connected to the inner cavity at the end away from the rotating shaft 32 through the synchronous belts 33, so that the movable shaft 34 rotates accordingly.
[0025] As one implementation method in this embodiment, please refer to Figures 1-3As shown, the inner cavity of the synchronous belt 33 away from the rotating shaft 32 is rotatably connected to a movable shaft 34, and the movable shaft 34 is rotatably connected to the upper surface of the base plate 1. The outer surface of the top end of the movable shaft 34 is fixedly connected to a rotating drum ring 35. The two sets of symmetrically arranged rotating drum rings 35 are rotatably connected to the upper side between the two sets of rollers included in the conveyor belt 2.
[0026] The rotating drum ring 35, which is fixedly connected to the outer surface of the top of the movable shaft 34, rotates synchronously with the rotation of the movable shaft 34. At this time, the steel drum is pushed onto the rotating drum ring 35 by the pushing mechanism 4. The rotation of the rotating drum ring 35 drives the steel drum to rotate together, so that the inkjet printer body 5 can perform a comprehensive and uniform inkjet printing operation on the rotating steel drum.
[0027] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the pushing mechanism 4 includes a first fixed column 41, which is fixedly connected to the top of the base plate 1 on one side. A cylinder 42 is fixedly connected to the top of the first fixed column 41, and a telescopic rod 43 is slidably connected to the inner cavity of the cylinder 42 at the end away from the motor 31.
[0028] After the conveyor belt 2 transports the steel drum to be printed to the designated position, the pushing mechanism 4 starts to work. The cylinder 42 at the top of the first fixed column 41 is activated, and the telescopic rod 43 in the inner cavity of the end of the cylinder 42 away from the motor 31 extends outward under the drive of the cylinder 42.
[0029] As one implementation method in this embodiment, please refer to Figure 4 As shown, a hinge 44 is fixedly connected to the end of the telescopic rod 43 away from the cylinder 42. A second fixed column 45 is rotatably connected to both sides of the hinge 44. A movable column 46 is fixedly connected to the bottom end of the second fixed column 45. A connecting shaft 49 is fixedly connected to the top end of the movable column 46. A pusher ring 410 is rotatably connected to the outer surface of the top end of the connecting shaft 49. The two sets of symmetrically arranged pusher rings 410 and rotating rings 35 are positioned correspondingly in the horizontal direction of the conveyor belt 2, and the pusher rings 410 and rotating rings 35 are respectively arranged on both sides of the conveyor belt 2 in the vertical direction.
[0030] As one implementation method in this embodiment, please refer to Figure 4 As shown, a third fixed post 47 is fixedly connected to one side of the top of the base plate 1. One end of the third fixed post 47 is fixedly connected to a guide shaft 48, and the guide shaft 48 is slidably connected to the inner cavity of the moving post 46.
[0031] The end of the telescopic rod 43 away from the cylinder 42 drives the second fixed column 45 to move via the hinge 44. Since the bottom end of the second fixed column 45 is fixedly connected to the moving column 46, the moving column 46 moves together with the second fixed column 45. During the movement of the moving column 46, the guide shaft 48 at one end of the third fixed column 47 at the top of the base plate 1 slides in the inner cavity of the moving column 46, guiding the movement of the moving column 46 and ensuring that the moving column 46 moves smoothly in a straight line. The connecting shaft 49 fixedly connected to the top of the moving column 46 moves accordingly, and the pusher ring 410 rotatably connected to the outer surface of the top of the connecting shaft 49 also moves. After the pusher ring 410 contacts the steel drum, it pushes the steel drum from the conveyor belt 2 onto the rotating drum ring 35 of the rotating mechanism 3, completing the transfer of the steel drum from the conveyor belt to the rotating inkjet printing position.
[0032] Working Principle: First, the barrel 6 to be printed is placed on the upper end of the conveyor belt 2. Since the conveyor belt 2 is horizontally arranged from the inlet to the outlet, the barrel 6 is stably conveyed horizontally under the action of the conveyor belt 2. When the barrel 6 is conveyed to the designated position near the outlet, the pushing mechanism 4 starts to operate. The cylinder 42 drives the telescopic rod 43 to extend, and through a series of connecting structures, drives the pusher ring 410 to push the barrel 6 from the conveyor belt 2 onto the rotating ring 35 of the rotating mechanism 3. During the pushing process, the guide shaft 48 ensures the smooth movement of the moving column 46, while the hinge 44 provides a certain buffering and adjustment function. After the barrel 6 reaches the rotating ring 35, the rotating mechanism 3 starts to work. The motor 31 drives the rotating shaft 32 to rotate, and transmits power to the movable shaft 34 through the synchronous belt 33, causing the rotating ring 35 to rotate, thereby driving the barrel 6 to rotate. At this time, the inkjet printer 5, fixedly connected to the side of the conveyor belt 2 near the discharge end, begins to operate. Since the inkjet printer 5 is positioned directly above the rotating mechanism 3, it can accurately perform inkjet printing on the rotating drum 6 below. Throughout the process, the pushing mechanism 4 and the rotating mechanism 3 are on the same horizontal plane in the vertical direction of the conveyor belt 2, ensuring that the drum 6 is pushed to the rotating mechanism 3 at a consistent height, thus ensuring a smooth inkjet printing process. After inkjet printing is completed, the relevant mechanisms reset, waiting for the next drum 6 to enter the inkjet printing process, thereby achieving continuous and efficient inkjet printing operation on the steel drums.
