[0014] Furthermore, collecting troughs are fixedly installed on the left and right sides of the lower cleaning scraper respectively, and the ceramic metallization printing paste scraped off by the lower cleaning scraper falls into the collecting trough for recovery.

[0015] Furthermore, the printing screen and the lifting frame can be disassembled and installed, which is convenient for repairing or replacing the printing screen.
