Description

Technical Field

[0001] This utility model relates to a satellite-type flexographic printing machine, belonging to the technical field of flexographic printing machines. Background Technology

[0002] Flexographic printing presses mainly consist of four units: an unwinding unit, a traction unit, a printing unit, and a rewinding unit. With technological advancements, non-stop unwinding and rewinding units have been developed. The unwinding unit unfolds the rolled printing substrate and continuously and stably transports it to the next stage. The traction unit, located before the printing unit, controls the speed, tension, and lateral position of the printing substrate. The printing unit is the core unit of the flexographic printing press, employing a short ink path inking system. Currently, drying is integrated within the printing unit. After printing, the printing substrate is dried and then rewound for storage or subsequent processing. To ensure smooth processing, the rewinding process ensures uniform tension, neat end faces, and regular outer contours of the rewound printing substrate.

[0003] Currently, many printing and packaging industries use traditional "bottom-feed" and "top-feed" flexographic printing presses. In practice, "bottom-feed" flexographic printing presses have a series of drawbacks: because the paper path is at the bottom, close to the bottom surface, the printing substrate will absorb dust from the bottom, leading to ink splatter and leakage during printing; it is also inconvenient to pass the paper through the printing substrate. "Top-feed" flexographic printing presses have a series of drawbacks: because the paper path is at the top, the height is too high, making it inconvenient to pass the paper through the printing substrate; the paper path is too long when printing substrate; misalignment of the frame installation can easily cause misregistration; the center of gravity is too high, causing resonance when the fan is running, affecting registration; and the equipment occupies a large area, among other problems. This not only reduces printing efficiency but also leads to waste of materials and labor. Furthermore, the positions of the anilox roller and printing plate roller in existing technologies are not easily adjustable automatically, making it impossible to adjust the pressure and printing accuracy during the printing process.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This invention addresses the shortcomings of the prior art by providing a satellite-type flexographic printing machine that can precisely control the displacement of the anilox roller and the printing plate roller, flexibly adjust the printing effect on paper, and has a simple structure, reasonable design, and convenient installation.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] A satellite-type flexographic printing machine includes two parallel wall panels, which are fixedly connected by a support roller, and a printing roller is provided in the middle of the two wall panels.

[0008] Multiple printing components are arranged around the printing roller. Each printing component includes a printing plate roller and an anilox roller. The printing plate roller is disposed close to the surface of the printing roller, and the anilox roller is disposed in close contact with the printing plate roller.

[0009] Furthermore, the printing assembly comprises six components, with three printing assemblies symmetrically arranged on each side of the printing roller.

[0010] Furthermore, each end of the anilox roller is provided with an anilox roller mounting seat, and the anilox roller is rotatably mounted on the anilox roller mounting seat. Each end of the printing plate roller is provided with a printing plate mounting seat, and the printing plate roller is rotatably mounted on the printing plate mounting seat. The anilox roller mounting seat and the printing plate mounting seat are slidably mounted on the outside of the wall panel via guide rails.

[0011] Furthermore, a first lead screw is provided on one side of the printing roller mounting base. The first lead screw is rotatably engaged with the printing roller mounting base via a thread. The first lead screw is rotatably mounted on a first motor base. A first adjusting motor is mounted on the first motor base. The rotating shaft of the first adjusting motor is connected to the first lead screw.

[0012] Furthermore, the printing roller mounting base is provided with a nut block, the screen roller mounting base is fixed with a second motor base, the second motor base is rotatably mounted with a second lead screw, the second lead screw is threadedly engaged with the nut block, the second motor base is mounted with a second adjusting motor, and the rotating shaft of the second adjusting motor is connected to the second lead screw.

[0013] Furthermore, a guide rail is provided at both the upper and lower positions of the printing roller mounting base and the screen roller mounting base, and the guide rail is set horizontally.

[0014] Furthermore, a first drive motor is installed on one side of the anilox roller mounting base to drive the anilox roller, and a second drive motor is installed on the printing roller mounting base to drive the printing plate roller.

[0015] Furthermore, a first paper guide roller, a second paper guide roller, a third paper guide roller, and a fourth paper guide roller are rotatably arranged between the wall panels.

[0016] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0017] The first lead screw rotates, causing the printing roller mounting base and the anilox roller mounting base to move horizontally as a whole. This pulls the printing roller and the anilox roller horizontally, adjusting the distance between them and the substrate roller, thereby adjusting the pressure of the printing roller on the substrate roller and thus the printing effect on the paper. The second lead screw moves the printing roller mounting base and the anilox roller mounting base closer or further apart, adjusting the distance between the printing roller and the anilox roller, thereby adjusting the amount of ink applied from the anilox roller to the printing roller and thus the printing effect. Both the first and second adjusting motors are servo motors, which can precisely control the displacement of the anilox roller and the printing roller, and are simple in structure, reasonable in design, and easy to install.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0025] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, this utility model provides a satellite-type flexographic printing machine, including two parallel wall panels 1, which are fixedly connected by a support roller 2, and a printing roller 7 is provided in the middle of the two wall panels 1.

[0027] Multiple printing components are arranged around the printing roller 7. Each printing component includes a printing plate roller 8 and an anilox roller 9. The printing plate roller 8 is arranged close to the surface of the printing roller 7, and the anilox roller 9 is arranged in close contact with the printing plate roller 8.

[0028] During printing, the paper is wound around the surface of the printing roller 7 and is driven by the anilox roller 9, which is used to pick up ink. The anilox roller 9 and the printing plate roller 8 are set in close contact with each other, so that the anilox roller 9 applies ink to the printing plate roller 8, and the printing plate roller 8 prints on the paper on the surface of the printing roller 7.

[0029] The printing assembly consists of six parts, with three printing assemblies symmetrically arranged on each side of the printing roller 7.

[0030] The anilox roller 9 is provided with an anilox roller mounting seat 11 at both ends, and the anilox roller 9 is rotatably mounted on the anilox roller mounting seat 11. The printing plate roller 8 is provided with a printing plate mounting seat 10 at both ends, and the printing plate roller 8 is rotatably mounted on the printing plate mounting seat 10. The anilox roller mounting seat 11 and the printing plate mounting seat 10 are slidably mounted on the outside of the wall panel 1 via the guide rail 18.

[0031] A first lead screw 12 is provided on one side of the printing roller mounting base 10. The first lead screw 12 is rotatably engaged with the printing roller mounting base 10 via a thread. The first lead screw 12 is rotatably mounted on the first motor base 141. A first adjusting motor 14 is mounted on the first motor base 141. The rotating shaft of the first adjusting motor 14 is connected to the first lead screw 12.

[0032] The printing roller mounting base 10 is provided with a nut block 101, the screen roller mounting base 11 is fixed with a second motor base 151, a second lead screw 13 is rotatably mounted on the second motor base 151, the second lead screw 13 is threadedly engaged with the nut block 101, a second adjusting motor 15 is mounted on the second motor base 151, and the rotating shaft of the second adjusting motor 15 is connected to the second lead screw 13.

[0033] A guide rail 18 is provided at both the upper and lower positions of the printing roller mounting base 10 and the screen roller mounting base 11, and the guide rail 18 is set horizontally.

[0034] The first adjusting motor 14 drives the first lead screw 12 to rotate, thereby causing the printing roller mounting base 10 and the anilox roller mounting base 11 to move horizontally as a whole. This pulls the printing roller 8 and the anilox roller 9 horizontally, adjusting the distance between them and the printing roller 7, thus adjusting the pressure of the printing roller 8 on the printing roller 7, and consequently adjusting the printing effect on the paper. When the second adjusting motor 15 drives the second lead screw 13, it can cause the printing roller mounting base 10 and the anilox roller mounting base 11 to move closer or further apart, thereby adjusting the distance between the printing roller 8 and the anilox roller 9, thus adjusting the amount of ink applied from the anilox roller 9 to the printing roller 8, and consequently adjusting the printing effect. Both the first adjusting motor 14 and the second adjusting motor 15 are servo motors, which can precisely control the displacement of the anilox roller 9 and the printing roller 8, and are simple in structure, reasonable in design, and convenient to install.

[0035] A first drive motor 16 is installed on one side of the anilox roller mounting base 11. The first drive motor 16 is used to drive the anilox roller 9. A second drive motor 17 is installed on the printing roller mounting base 10. The second drive motor 17 is used to drive the printing plate roller 8.

[0036] A first paper guide roller 3, a second paper guide roller 4, a third paper guide roller 5, and a fourth paper guide roller 6 are rotatably arranged between the wall panels 1. The first paper guide roller 3, the second paper guide roller 4, the third paper guide roller 5, and the fourth paper guide roller 6 are used to guide the conveyed paper.
