Technical Field

[0002] A silk screen printer is a type of printing equipment. Its full name is a screen printer. Its basic principle is to transfer ink through the mesh of the screen plate to the surface of the printing object (substrate) through the extrusion of a scraper, thereby forming images. The image part on the screen plate is a transparent mesh, and the ink can pass through; the non-image part is blocked by the plate-making material, and the ink cannot pass through. It is like using a template with holes for spraying paint, only the holes can be sprayed with paint. In a silk screen printer, only the mesh part can be printed with ink.

[0003] In daily work, it is found that the traditional silk screen printing structure has many parts and is mainly driven by cylinders. The installation is cumbersome. When in use, the printing efficiency is low and the adjustment is inconvenient. The cylinder is noisy and has a short life. The synchronization between the connected actions is inconsistent, resulting in low production efficiency and poor stability. Utility Model Content

A servo motor is installed on the surface of the fixed base plate, and a connecting rod mechanism is provided between the output end of the servo motor and the drive shaft, the rotating connecting shaft, and the lifting slide rail mounting plate 2. A transmission mechanism is provided between the rotating connecting shaft and the lifting slide rail mounting plate 1;

[0007] One end of the driving shaft is provided with a grabbing mechanism 1, the surface of the rotating connecting seat is provided with a grabbing mechanism 2, and the rotating connecting shaft is respectively provided with a grabbing mechanism 3, a grabbing mechanism 4 and a grabbing mechanism 5.
