Segment-driven automatic single-tool silk screen printing device

The invention relates to the textile machinery technology, in particular to a segment-driven automatic single-tool silk screen printing device. The device comprises an oval rail and printing table plates, wherein two adjacent printing table plates are connected through a rigid connection rod; a driving device is arranged on the inner side of the oval rail; a single-tool scraper-printing and ink-returning device is arranged right above a printing table plate in a working station; the driving device and the single-tool scraper-printing and ink-returning device both are electrically connected to a control device. According to the segment-driven automatic single-tool silk screen printing device, the two adjacent printing table plates are connected through the rigid connection rod, so that the pulling force and the pushing force can be transmitted; the device has rigidity, so that the problem that the positioning is inaccurate, caused by the flexibility of a chain can be overcome; the driving device is driven by a servo motor; by integrating the control of a programmable controller with the feedback of a photoelectric switch position, the device is high in automation degree and is accurate to position; two main actions of scraper printing and ink returning of printing can be implemented by the single tool; the printing process is simplified; the structure is simplified; the manufacturing process is simple; the device cost is reduced; the scraper printing and ink returning are implemented by using one action; the printing speed is high; the production efficiency is improved.
