[0002] Printing technology refers to the technology of copying text, images and colors onto various substrates. Common printing technologies are divided into several types, such as letterpress printing, gravure printing, screen printing, and flexographic printing. Among them, screen printing is a printing technology that uses a screen to press ink onto the substrate.

[0003] Simply put, the worker first places the substrate under the screen and evenly applies ink on the screen. Then, a scraper or roller is used to apply pressure on the screen, so that the ink is transferred through the grid on the screen to the substrate.

[0004] Workers usually manually tilt the container and slowly move it from one end of the screen along the length of the screen to evenly pour the ink onto the screen. This process requires high operating skills of the workers. Once the operation is not careful, it may cause ink accumulation or uneven ink distribution, which will affect the subsequent printing effect. After pouring the ink, when the worker moves the scraper or roller to transfer the ink to the substrate, it is difficult to control the moving speed of the scraper or roller manually. Therefore, a printing device with an ink supply device is needed to solve the above problems. Utility Model Content

[0034] The stamping device 3 further includes a rotating handle 37 , which is mounted on the end of the rotating rod 35 .

[0035] The working principle and use process of this utility model:

[0036] The printing material is placed flatly under the screen 1. In the initial state, the ink supply tube 21 is in a horizontal state. The motor 25 drives the belt rotating rod 26 to rotate, causing the active bevel gear 22 to rotate along the belt rotating rod 26 along the axial direction of the belt rotating rod 26. This in turn drives the driven bevel gear 23 engaged with the active bevel gear 22 to rotate synchronously, causing the ink supply tube 21 to rotate synchronously around its own center. That is, the ink supply tube 21 rotates intermittently from a horizontal state to an inclined state. Under the action of gravity, the ink in the ink supply tube 21 is evenly distributed along the axial direction of the ink supply tube 21 as the ink supply tube 21 tilts.

[0037] After the ink in the ink supply tube 21 is evenly distributed and the ink supply tube 21 is in a horizontal state, the worker then moves the telescopic column 211 upward along the axial direction of the telescopic cylinder 212, thereby driving the movable column 29 to move upward in a direction away from the screen 1, so that the flow control ball 27 is separated from the hole where the ink supply tube 21 connects to the ink outlet nozzle 24. In this way, the ink flows from the ink supply tube 21 to the screen 11 through the ink outlet nozzle 24. This is a simple operation without the need for the worker to tilt the container containing ink. At the same time, it better ensures the uniformity of the ink flowing to the screen 11, thereby improving the degree of automation of the printing equipment.

[0038] After an appropriate amount of ink flows to the screen 11, the handle 37 is rotated, and the rotating rod 35 rotates along its own axis, thereby driving the active bevel gear 34 and the driven bevel gear 36 meshing with the active bevel gear 34 to rotate synchronously, so that the rotating screw 32 rotates along its own axis, so that the stamping member 31 arranged between the two belt shifting blocks 33 moves along the axial direction of the rotating screw 32, and the moving stamping member 31 evenly applies the ink to the entire screen 11; at this time, the pressure applied by the stamping member 31 to the screen 11 is uniform, ensuring that the ink transferred to the substrate under the screen 1 is evenly colored, thereby improving the printing quality.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
