Description

Technical Field

[0001] The utility model belongs to the technical field of printing equipment, and more specifically, relates to a printing mechanism of a flexible perovskite battery roll-to-roll printing equipment. Background Art

[0002] As a kind of printing process, gravure printing of ink has extremely important status in the fields of printing and packaging and graphic publishing due to its advantages such as thick ink layer of printed products, bright colors, high saturation, high printing resistance of printing plates, stable printed product quality, and fast printing speed. Currently, general gravure printing machines generally include pressure rollers, printing rollers, ink tanks, scrapers, etc. A part of the plate cylinder is immersed in the ink to coat the ink on the gravure surface of the plate cylinder during the rotation of the plate cylinder, and then the ink on the plate surface is printed onto the substrate.

[0003] The existing patent authorization announcement number: CN 217835049 U, discloses a printing roller adjusting device for printing equipment, including a bottom plate, a first-level column, a second-level column and a servo motor. Transverse tracks are respectively opened on both sides of the upper surface of the bottom plate, and the first-level column and the second-level column are respectively inserted into the two transverse tracks. The first-level column and the second-level column are respectively slidably connected with the two transverse tracks. A second-level printing roller is fixedly installed between the bottoms of the first-level column and the second-level column through a bearing. Longitudinal tracks are respectively opened on the outer walls of the opposite sides of the first-level column and the second-level column. A threaded rod is rotatably installed in the longitudinal track of the second-level column. The utility model can achieve the double-axis adjustment effect of the X and Y axes, has good usability in actual use, can meet different working requirements, has a wide range of use, and can meet the technical requirements of double-axis adjustment through a single motor and a telescopic rod. During equipment processing, the production and processing costs can be greatly reduced, and during use, electric power resources can be greatly saved, the printing cost can be reduced, and it is convenient to use.

[0004] However, the existing technology has the following problems: when adjusting the height of the printing roller, due to the certain weight of the printing roller itself, when only using a threaded rod for transmission at one end of the printing roller, the other end of the printing roller is greatly affected by gravity, and the overall printing roller will tilt, which affects the accuracy of the printing roller height adjustment, further affects the printing quality, and at the same time reduces the service life of the printing roller.

A film tearing device (30) is connected to both sides of the connecting plate (190) to tear off the protective films on the upper and lower surfaces of the film.

5. The printing mechanism of the flexible perovskite battery roll-to-roll printing equipment according to claim 4, characterized in that: The film tearing device (30) includes a film tearing shaft (301) and a film tearing shaft fixing seat (302). The film tearing shaft fixing seat (302) is connected to the connecting plate (190), and the film tearing shaft (301) is sleeved with the film tearing shaft fixing seat (302) and the connecting plate (190).

6. The printing mechanism of the flexible perovskite battery roll-to-roll printing equipment according to claim 5, characterized in that: The film tearing device (30) includes a first film tearing device (303) and a second film tearing device (304). The first film tearing device (303) is used to tear off the protective film on the lower surface of the film, and the second film tearing device (304) is used to tear off the protective film on the upper surface of the film. The first film tearing device (303) and the second film tearing device (304) are connected to one side of the connecting plate (190). On the other side of the connecting plate (190), there are a second servo motor (200), a second driving wheel (210), a synchronous wheel (220) and a synchronous belt (230). The second driving wheel (210) is connected to the film tearing shaft (301) of the first film tearing device (303), and the synchronous wheel (220) is connected to the film tearing shaft (301) of the second film tearing device (304). The second driving wheel (210) and the synchronous wheel (220) are connected by the synchronous belt (230), and the second servo motor (200) is connected to the second driving wheel (210), so that the first film tearing device (303) and the second film tearing device (304) rotate synchronously.

7. The printing mechanism of the flexible perovskite battery roll-to-roll printing equipment according to claim 6, characterized in that: A third groove (240) is provided on the film tearing shaft (301), and a limit clamping column (250) matching the third groove (240) is provided to increase the interaction force between the film tearing shaft (301) and the protective film.

8. The printing mechanism of the flexible perovskite battery roll-to-roll printing equipment according to claim 7, characterized in that: A limit hole (260) is further provided on the film tearing shaft (301), and a limit post (270) matching the limit hole (260) is provided to limit the left and right movement of the protective film after rewinding.

9. The printing mechanism of the flexible perovskite battery roll-to-roll printing equipment according to claim 1, characterized in that: A guide roller (280) is provided on one side of the second bracket (80) close to the unwinding roller (50), which plays a role in supporting and stabilizing when the protective film is torn off.

10. The printing mechanism of the flexible perovskite battery roll-to-roll printing equipment according to claim 1, characterized in that: Reinforcing plates (290) are provided on both sides of the support plate (100) to make the support plate (100) more stable.
