[0015] An automatic printing device for marble slate glass, the printing process of which comprises the following steps:

[0016] S1: The staff starts the motor, and the transmission belt starts to transmit under the influence of the cylindrical rod. The fixed block and the printing roller are adjusted to the appropriate height of the marble slab glass through the hydraulic rod. Then the marble slab glass is placed on the transmission belt.

[0020] S5: The elastic force of spring 3 is transmitted to the circular wheel through sliding plate 2 and thin rod, so that the circular wheel supports the triangular scraper from the bottom. The triangular scraper can scrape off some impurities attached to the outer surface of the friction rod and collect them in the cleaning box for storage.

[0021] The present invention has the beneficial effects

[0022] The present invention uses a fixed block. When the printing roller needs to be replaced, the hydraulic rod is used to lift the fixed block to the maximum height. Then the staff pinches the long plate with their fingers and pulls it outward. The connecting block will drive the right-angle rod to move together. The staff can replace the printing roller, thereby achieving the effect of limiting the position of the printing roller. At the same time, the disassembly and installation methods are relatively simple.

[0023] The present invention uses a bottom plate and a hydraulic rod to adjust the fixed block and the printing roller to a suitable height of the marble slab glass, and then places the marble slab glass on a transmission belt. The printing roller will automatically print, thereby achieving the effect of automatic printing. The position of the printing roller can be adjusted by the hydraulic rod, so that the printing roller can print on marble slab glass of different heights, thereby improving the practicality of the device.

[0024] The present invention uses an extrusion component. When the marble slab glass is placed on the transmission belt, the extrusion plate affected by the pressure of the spring will push the marble slab glass to the central axis of the transmission belt, thereby adjusting the position of the marble slab glass, avoiding the situation where the marble slab glass will affect the printing effect due to its own inclination, and indirectly improving the printing effect of the marble slab glass.

[0025] The present invention uses a cleaning component. The top of the outer surface of the friction rod located inside the cleaning box will be in close contact with the bottom of the outer surface of the transmission belt under the push of spring 2. Through the friction force between the friction rod and the transmission belt, some impurities adsorbed on the transmission belt will be removed, thereby achieving the effect of cleaning the transmission belt, so that impurities will not be adsorbed on the marble slab glass and affect the printing of the marble slab glass.

[0026] The present invention uses a scraping assembly, and the elastic force of spring three is transmitted to the circular wheel through sliding plate two and a thin rod, so that the circular wheel supports the triangular scraper from the bottom. The triangular scraper can scrape off some impurities attached to the outer surface of the friction rod and collect them in a cleaning box for storage, thereby avoiding the outer surface of the friction rod absorbing too many impurities, thereby reducing the cleaning effect of the friction rod on the transmission belt. The triangular setting of the triangular scraper can reduce the problem of impurities adhering to the outer surface of the top of the triangular scraper for a long time due to static electricity due to its own inclined plane.

At this time, the cylindrical block 52 is no longer restricted by the right-angle rod 53, and the staff can replace the printing roller 51.

[0056] When the marble slate glass 4 is placed on the transmission belt 24, the extrusion plate 33 affected by the pressure of the spring will push the marble slate glass 4 to the central axis of the transmission belt 24, thereby adjusting the position of the marble slate glass 4;

[0057] The friction rod 46 located inside the cleaning box 41 is pushed by the spring 2, and the top of its outer surface is in close contact with the bottom of the outer surface of the transmission belt 24.

6. The automatic printing device for marble slab glass according to claim 5, characterized in that: The positioning rod (303) is internally slidably connected to a second sliding plate (305), the top of the second sliding plate (305) is fixedly connected to a thin rod (306), the inner surface of the triangular scraper (304) is provided with a sliding groove, the sliding groove is slidably connected to a circular wheel (308), the end of the thin rod (306) away from the second sliding plate (305) is internally fixedly connected to a second rotating shaft (307), the left and right ends of the second rotating shaft (307) are rotatably connected to the circular wheel (308), the bottom of the fixed rod (301) is fixedly connected to the inner surface of the fixed arc plate (422), and the top of the triangular scraper (304) is in contact with the outer surface of the friction rod (46); A spring three is provided inside the positioning rod (303), one end of the spring three is fixedly connected to the sliding plate two (305), and the other end of the spring three is fixedly connected to the inner wall of the positioning rod (303).

7. A printing process using an automatic printing device for marble slab glass according to claim 6, characterized in that: The printing process consists of the following steps: S1: The staff starts the motor (25), and the transmission belt (24) starts to transmit under the influence of the cylindrical rod (21). The fixed block (5) and the printing roller (51) are adjusted to a height suitable for the height of the marble slab glass (4) by the hydraulic rod (101). Then, the marble slab glass (4) is placed on the transmission belt (24). When the marble slab glass (4) moves to a certain position following the transmission belt (24), the printing roller (51) automatically prints, thereby achieving the function of automatic printing; S2: When the printing roller (51) needs to be replaced, the fixed block (5) is raised to the maximum height by using the hydraulic rod (101). Then, the staff member pinches the long plate (55) with his fingers and pulls it outward. The connecting block (54) drives the right-angle rod (53) to move together. At this time, the cylindrical block (52) loses the restriction of the right-angle rod (53), and the staff member can replace the printing roller (51). S3: When the marble slate glass (4) is placed on the transmission belt (24), the extrusion plate (33) affected by the pressure of the second spring will push the marble slate glass (4) onto the central axis of the transmission belt (24), thereby adjusting the position of the marble slate glass (4); S4: The top of the outer surface of the friction rod (46) located inside the cleaning box (41) is pushed by the spring to contact the bottom of the outer surface of the transmission belt (24) more closely. Through the influence of the friction force between the friction rod (46) and the transmission belt (24), some impurities adsorbed on the transmission belt (24) are removed; S5: The elastic force of the spring 3 is transmitted to the circular wheel (308) through the sliding plate 2 (305) and the thin rod (306), so that the circular wheel (308) supports the triangular scraper (304) from the bottom. The triangular scraper (304) can scrape off some impurities attached to the outer surface of the friction rod (46) and collect them in the cleaning box (41) for storage.
