Adjusting the top rod forward and backward changes the gap between the doctor blade and the ink roller, thus controlling the amount of ink on the ink roller surface.

[0007] Preferably, the ink filling port has an inverted conical tail end structure surrounded by a metal sheet, and the ink filling port is located at the top of the ink fountain to facilitate the addition of ink and ensure continuous operation of the equipment.

[0008] Preferably, the ink outlet is a through-hole structure, which is attached to the tail end of the doctor blade and set on the side of the ink fountain. This facilitates the flow of ink from the ink fountain to the doctor blade. The ink on the doctor blade is evenly adhered to the surface of the ink roller through the tiny gap between the end of the doctor blade and the ink roller, thereby realizing the next printing step of the printing machine.

[0009] Preferably, the ink roller support is a metal sheet structure. The ink roller support is set at the front end of the ink adjustment table and extends upward at an angle. The upper end of the ink roller support is circumferentially inserted into the center of the ink roller to ensure that the ink roller is stably fixed.

[0010] Beneficial effects: This solution provides an ink supply adjustment device for printing ink rollers to improve the situation where general printing machines require changing inks of different viscosities and ink fountains when changing to different types of printed materials, which inadvertently extends the production cycle. This utility model adjusts the gap between the doctor blade and the ink roller through the ink supply adjustment device, so as to adapt to inks of different viscosities in the ink fountain, cope with the production of various printed materials, and thus improve production efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] The ink mixing table 1 is an L-shaped structure with angled corners, made of metal rectangular blocks. It is fixed to the printing press, providing a printing platform and facilitating the installation of subsequent parts. The plane of the ink mixing table 1 is parallel to the horizontal plane, facilitating the installation of the ink fountain 2. The ink fountain 2, a groove-like structure surrounded by metal sheets, is used for printing ink and serves as the ink source for the printing machine. It is positioned at the top of the vertical wall of the ink mixing table 1, parallel to it, ensuring stable installation. The doctor blade 3 is an elastic sheet structure with strong resilience, allowing the push rod 7 to move back and forth, changing the gap between the doctor blade 3 and the ink roller 4. This allows for adjustment of the ink volume by changing the gap size. The doctor blade 3 is located at the ink outlet of the ink fountain 2 and extends forward, near the ink roller 4. The ink roller 4 is cylindrical with a flexible surface that easily adheres to ink, ensuring uniform ink adhesion and clear printing. The ink roller 4 is mounted via an ink roller bracket. At the front end of the ink leveling table 1, ink flows easily from the ink fountain 2 to the doctor blade 3. The tiny gap between the doctor blade 3 and the ink roller 4 allows the ink to adhere evenly to the surface of the ink roller 4. The ends of the ink roller 4 and the doctor blade 3 are parallel and nearly non-contact, maintaining a tiny gap to ensure continuous ink adhesion to the surface of the ink roller 4. The adjusting rotating rod 5 is a spiral metal rod structure for easy rotation adjustment. The adjusting rotating rod 5 is parallel to the platform of the ink leveling table 1 and is spirally adjustable through the vertical wall at the rear end of the ink leveling table 1. The top rod spring 6 is a spring structure. Multiple top rod springs 6 are grouped together at the front end of the adjusting rotating rod 5 via metal plates. Adjusting the rotation of the adjusting rotating rod 5 extends and retracts the top rod spring 6, thereby adjusting the top rod 7 back and forth. The top rod 7 is a metal sheet structure. The tail end of the top rod 7 is located in front of the top rod spring 6, and the front end of the top rod 7 contacts the rear end face of the doctor blade 3. Adjusting the top rod 7 back and forth changes the gap between the doctor blade 3 and the ink roller 4, thereby adjusting the amount of ink on the surface of the ink roller 4.

[0016] Furthermore, the ink filling port 8 has an inverted conical tail end structure surrounded by a metal sheet. The ink filling port 8 is located at the upper end of the ink fountain 2, which facilitates the addition of ink and ensures continuous operation of the equipment.

[0017] Furthermore, the ink outlet 9 is a through-hole structure. The ink outlet 9 is attached to the tail end of the doctor blade 3 and set on the side of the ink fountain 2, so that the ink can flow from the ink fountain 2 to the doctor blade 3. The ink on the doctor blade 3 is evenly attached to the surface of the ink roller 4 through the tiny gap between the end of the doctor blade 3 and the ink roller 4, thereby realizing the next printing step of the printing machine.

[0018] Furthermore, the ink roller support 10 is a metal sheet structure. The ink roller support 10 is set at the front end of the ink adjustment table 1 and extends upward at an angle. The upper end of the ink roller support 10 is circumferentially inserted into the center of the ink roller 4 to ensure that the ink roller 4 is stably fixed.

[0019] Working steps: Ink is added to the ink fountain through the ink inlet. The ink flows from the ink outlet at the lower front of the ink fountain to the doctor blade. The tiny gap between the doctor blade and the ink roller allows the ink to adhere evenly to the ink roller, thus enabling the next printing step. The adjusting rotary rod located on the ink adjustment table can rotate to adjust the tension of the top rod spring. The extension and retraction of the top rod spring allows the top rod to move back and forth. Adjusting the back and forth of the top rod adjusts the size of the gap between the ink roller and the doctor blade. Specifically, moving the top rod backward increases the gap between the ink roller and the doctor blade, facilitating the smooth and even adhesion of inks with high viscosity to the ink roller; moving the top rod forward decreases the gap between the ink roller and the doctor blade, facilitating the smooth and even adhesion of inks with low viscosity and high fluidity to the ink roller, thus enabling the next printing step.
