Segment-driven automatic single-tool silk screen printing device

Abstract

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.

Description

technical field [0001] The invention relates to textile machinery technology, in particular to a screen printing device with single-knife one-time scraping and ink return with segmental transmission. Background technique [0002] The screen printing process is more complicated, so there are many stations. In addition, in order to improve work efficiency, the screen printing is generally set to an elliptical orbit or a circular orbit. The circular orbit is easy to drive, but the stations are fixed and cannot be added at will. The drive of the elliptical orbit is more complicated, but the station is flexible, and the station can be added in the straight section according to the need. At present, the transmission of the elliptical track mostly adopts the chain transmission method, and each printing table is connected to the chain. Due to the flexibility of the chain, the transmission accuracy of this method is not high, which makes the subsequent printing incorrect. In additio...

Problems solved by technology

At present, the transmission of the elliptical track mostly adopts the chain transmission method, and the printing plates are connected to the chain. Due to the flexibility of the chain, the transmission accuracy of this method is not high, which makes the subsequent printing incorrect.

In addition, the traditional screen printing scraping and ink return are usually realized by two knives alternately rising and falling, which has the problems of complex mechanism, inconvenient operation and adjustment, and low production efficiency.
