Automatic single-knife screen printing device with segmented drive

Abstract

The invention relates to textile machinery technology, in particular to an automatic single-knife screen printing device with segmental transmission, which includes an elliptical track and a printing platen, and two adjacent printing platens are connected by rigid connecting rods; a transmission device is arranged inside the elliptical track, A single-knife scraping and ink return device is arranged directly above the printing table of the working station, and the transmission device, single-knife scrape and ink return device are all electrically connected to the control device. In the present invention, two adjacent printing plates are connected by a rigid connecting rod, which can transmit both pulling force and pushing force, and has rigidity, which overcomes the problem of inaccurate positioning caused by the flexibility of the chain; the transmission device is driven by a servo motor and cooperates with a programmable controller Control, photoelectric switch position feedback, high degree of automation, and accurate positioning; single-knife realizes the main two actions of printing scraping and ink return, simplifies the printing process, simplifies the mechanism, simple manufacturing process, and reduces device costs; scraping and ink return adopts One action is realized, the printing speed is fast, and 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...

AI Technical Summary

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.
