Description

Technical Field

[0001] This utility model relates to the field of screen printing machine cutter heads, specifically a cutter head mechanism for a two-station servo fully automatic shuttle screen printing machine. Background Technology

[0002] In screen printing equipment production, the cutter head (squeegee) mechanism plays an important role. The cutter head is responsible for printing the paste on the screen printing frame onto the film.

[0003] Existing cutting head mechanisms apply appropriate pressure during the printing process to push ink through openings in the screen, allowing the ink to be transferred to the substrate and ensuring the clarity and accuracy of the printed pattern.

[0004] However, when the cutting head applies pressure to transfer ink through the screen onto the substrate, the contact between the cutting head and the screen will generate a certain impact force. These impacts may not only affect the printing quality, but also cause the cutting head to wear faster and shorten its service life. Utility Model Content

[0025] Please see Figures 1-6 The present invention provides the following two preferred embodiments: a cutter head mechanism for a two-station servo fully automatic shuttle screen printing machine;

[0026] Example 1:

[0027] To mitigate the impact energy of the squeegee 20 contacting the screen printing mesh surface, a movable rod 2 is provided on the lower surface of the blade holder 1. A first spring 3 is sleeved on the outer surface of the movable rod 2. A buffer mechanism is fixedly installed on the lower surface of the movable rod 2. The buffer mechanism includes: a connecting plate 9, a second sliding groove 10 on the inner surface of the connecting plate 9, a second sliding rod 11 fixedly installed on the inner side of the second sliding groove 10, a second spring 13 sleeved on the outer surface of the second sliding rod 11, a second sliding plate 12 slidably installed on the outer surface of the second sliding rod 11, an installation groove 14 on the inner surface of the second sliding plate 12, a connecting rod 15 rotatably installed on the inner side of the installation groove 14, a first sliding groove 6 on the inner surface of the blade holder 1, a first sliding rod 7 fixedly installed on the inner side of the first sliding groove 6, a first sliding plate 8 slidably installed on the outer surface of the first sliding rod 7, and the connecting rod 15 is away from the first spring 3. One end of the second sliding plate 12 is rotatably connected to the first sliding plate 8. A sliding sleeve 5 is fixedly installed on the upper surface of the connecting plate 9. The sliding sleeve 5 is sleeved on the outer surface of the movable rod 2. When the squeegee 20 contacts the screen printing mesh surface, it drives the connecting plate 9 to rise. The sliding sleeve 5 moves upward to compress the first spring 3 on the movable rod 2. Then, the second sliding plate 12 in the second sliding groove 10 squeezes the second spring 13 on the second sliding rod 11. The connecting rod 15 in the mounting groove 14 is connected to the first sliding plate 8 on the first sliding rod 7 to achieve synchronous movement. This can ensure that the squeegee 20 maintains stable pressure throughout the entire stroke, avoid pressure fluctuations caused by impact, thereby ensuring the consistency of ink transfer, improving printing quality, and helping the squeegee 20 absorb and disperse impact energy by reducing impact, reducing wear rate, and extending the overall service life of the squeegee 20.

[0028] Example 2:

[0029] Based on Embodiment 1, in order to achieve the angle adjustment of the scraper 20 and obtain the best printing effect, an angle adjustment mechanism is fixedly installed on the lower surface of the connecting plate 9. The angle adjustment mechanism includes: a limiting groove 16, two fasteners 17 are fixedly installed on the inner surface of the limiting groove 16, a clamping plate 18 is rotatably installed on the inner side of the fasteners 17, a pin 19 is provided on the outer side of the clamping plate 18, the fasteners 17 are rotatably connected to the clamping plate 18 through the pin 19, the scraper 20 is fixedly installed on the inner side of the clamping plate 18, and a nut 21 is fixedly installed at the bottom end of the movable rod 2. The movable rod 2 is fixedly connected to the connecting plate 9 through the nut 21.

[0030] Working principle: In order to reduce the impact energy of the squeegee 20 contacting the screen printing mesh surface, the connecting plate 9 is raised when the squeegee 20 contacts the screen printing mesh surface. The sliding sleeve 5 moves upward to compress the first spring 3 on the movable rod 2. Then, the second slide plate 12 in the second slide groove 10 squeezes the second spring 13 on the second slide rod 11. The connecting rod 15 in the mounting groove 14 connects with the first slide plate 8 on the first slide rod 7 to achieve synchronous movement. This ensures that the squeegee 20 maintains stable pressure throughout the entire stroke, avoids pressure fluctuations caused by impact, and thus ensures the consistency of ink transfer, improves printing quality, and helps the squeegee 20 absorb and disperse impact energy by reducing impact, reducing wear rate, and extending the overall service life of the squeegee 20.
