The user adjusts the top of the limit plate to be higher than the glass, and then puts the glass on the surface of the conveying roller. Then the third motor is controlled to work. The output end of the third motor drives the first reverse threaded rod to rotate through the fourth gear, the third toothed belt and the fifth gear. The movable plate and the limit plate can be brought close to each other through two groups of first reverse threaded rods until the glass on the surface of the conveying roller is straightened and centered. Step 2: Move, the output end of the first motor drives the power roller to rotate through the third gear, the second toothed belt and the second gear, and then the power roller drives the conveying roller to rotate through the first gear and the first toothed belt, and the glass is driven to move through the conveying roller; Step 3: Automatic cleaning: the cleaning roller at the bottom of the cleaning box is made to fit the glass through the first electric push rod, the surface of the glass can be cleaned through the fifth motor and the cleaning roller, and the position of the cleaning box can be adjusted through the third sliding rod, the second threaded rod and the fourth motor; Step 4: Select printing.

If high-precision printing is required, the print head is selected for printing. The user can adjust the position of the second adjustment plate and the print head on the glass through the third threaded rod and the sixth motor. Step 5: Select printing. If the user needs large quantities and does not need high precision, the user should first place the screen body inside the lower moving box, fix the screen body through the electromagnet and the pressure plate, and make the first scraper and the second scraper inside the screen body through the third and fourth electric push rods. The bottom end of the second scraper is fitted with the screen body through the fourth electric push rod. The ink or paint enters the liquid separation chamber through the water pump and the water pipe, and then flows into the surface of the screen body through the flow channel. The second scraper is moved up by the fourth electric push rod so that it no longer fits the screen body. The lower moving box and the screen body can be moved down by the second electric push rod until the bottom end of the screen body fits with the surface of the glass. At this time, the first scraper is moved up by the third electric push rod. The first scraper is moved to fit the inner wall of the screen body, and then the electric slider drives the first scraper to move through the fixed plate and the third electric push rod, and the ink or paint is applied to the screen body through the first scraper to make it evenly covered. At the same time, the first scraper applies pressure to allow the ink or paint to penetrate into the surface of the glass plate through the mesh holes on the surface of the screen body. After scraping once, the third electric push rod lifts the first scraper, and the fourth electric push rod fits the bottom end of the second scraper to the bottom end of the screen body. Then the electric slider and the fixed plate reset the second scraper. At this time, the remaining ink or paint on the surface of the screen body can be scraped to one side by the second scraper, and then the second electric push rod drives the downward moving box and the screen body to reset. At this time, the bottom end of the screen body is no longer in contact with the surface of the glass, and printing is completed at this time. Step 6: Drying: The printed glass is moved to the bottom of the dryer by the conveyor roller, and the ink or paint can be dried by the dryer.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The user first adjusts the height of the limit plate according to the thickness of the glass, controls the operation of the second motor, and enables the limit plate to rise and fall through the first threaded rod. The user adjusts the top end of the limit plate to be slightly higher than the glass, and then places the glass on the surface of the conveyor roller, and then controls the third motor to work.

The movable plate and the limit plate can be brought close to each other through two sets of first reverse threaded rods until the glass on the surface of the conveyor roller is straightened and centered, thereby facilitating automatic centering and straightening of the glass. The moving trajectory of the glass can be limited through the limit plate to ensure the accuracy of subsequent processing, and at the same time, the movement of the glass on the conveyor roller can be ensured. Then the output end of the first motor drives the power roller to rotate through the third gear, the second toothed belt and the second gear, and then the power roller drives the conveying roller to rotate through the first gear and the first toothed belt, and the glass is moved by the conveying roller. When the glass moves to the bottom end of the cleaning bracket, the cleaning roller at the bottom end of the cleaning box is fitted with the glass through the first electric push rod, and the surface of the glass can be cleaned by the fifth motor and the cleaning roller. The position of the cleaning box can be adjusted by the third sliding rod, the second threaded rod and the fourth motor, which can not only adjust the cleaning position but also comprehensively clean the glass surface. When the glass moves to the bottom end of the printing bracket, the user can select different printing methods according to printing needs. If high-precision printing is required, , then select the print head to print, the user can adjust the position of the second adjustment plate and the print head on the glass through the third threaded rod and the sixth motor. If the user needs large quantities and does not need high precision, the user first places the screen body inside the lower moving box, and then fixes the screen body through the electromagnet and the pressure plate, and at the same time, the first scraper and the second scraper are placed inside the screen body through the third electric push rod and the fourth electric push rod, and the fixed plate, the first scraper and the second scraper are placed at one end of the screen body through the electric slider, and the bottom end of the second scraper is fitted with the screen body through the fourth electric push rod, and the ink or paint enters the inside of the liquid separation tank through the water pump and the water pipe, and then flows into the surface of the screen body through the flow channel, and then is re-adjusted by the fourth electric push rod The second scraper moves up so that it no longer fits with the screen body, and then the second electric push rod can move the downward box and the screen body downward until the bottom end of the screen body fits with the surface of the glass. At this time, the first scraper is fit with the inner wall of the screen body through the third electric push rod, and then the electric slider drives the first scraper to move through the fixed plate and the third electric push rod, and ink or paint is applied to the screen body through the first scraper to cover it evenly. At the same time, the first scraper applies pressure to allow the ink or paint to penetrate into the surface of the glass plate through the mesh holes on the surface of the screen body. After scraping once, the third electric push rod lifts the first scraper, and the fourth electric push rod fits the bottom end of the second scraper with the bottom end of the screen body, and then the electric slider and the fixed plate reset the second scraper.At this time, the second scraper can scrape the remaining ink or paint on the surface of the screen body to one side, and then the second electric push rod drives the lower box and the screen body to reset. At this time, the bottom end of the screen body is no longer in contact with the surface of the glass. At this time, printing is completed, and the printed glass is moved to the bottom end of the dryer through the conveyor roller. The dryer can dry the ink or paint. After drying, the user can take the printed glass away. This device is not only convenient for users to use, but also can select the appropriate printing method according to the different needs of users, thereby reducing the limitations of its use. At the same time, this device can also perform cleaning work before printing, which can not only ensure the quality of printing, but also improve its printing accuracy.
