Description

Technical Field

[0001] The utility model relates to the field of ink scrapers, in particular to a scraper stand for the ink scraper. Background Art

[0002] The printing press needs to be equipped with a scraper. The scraper on the printing press plays a vital role in the printing process. In gravure printing, flexographic printing, screen printing and other processes, the scraper is used to scrape off excess ink, leaving only the ink carried by the image part engraved on the anilox roller or the printing plate, thus ensuring that the ink is only transferred to the required printing area.

[0003] There are multiple printing machines and they are arranged in a row. Each printing machine is equipped with a corresponding scraper. When the pattern of the printed packaging film product is changed, the scraper also needs to be replaced. Therefore, a spare scraper rack is now manufactured. The scraper to be replaced is placed on the spare scraper rack in advance. One side of the spare scraper rack can be used to place the scraper to be replaced, and the other side can be used to place the removed scraper. However, in the process of taking or placing the scraper, it may be inconvenient to rotate and adjust the spare scraper rack, which greatly reduces the replacement efficiency and increases the downtime opportunity.

[0004] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content

Through the base 1 and the shaft 21, the other steel The position of the square steel 22 is adjusted. After the square steel 22 is rotated and adjusted to 180°, the insertion rod 25 passes through the upper circular hole 28 and penetrates the positioning plate 24 and is connected to one of the lower circular holes 23, thereby limiting the position of the square steel 22 after adjustment. Subsequently, the disassembled scraper is placed on the right-angle steel 33 of the inclined steel 32 on the other side of the T-shaped steel 38. The position of the inclined steel 32 can be adjusted by rotation, thereby improving the efficiency of scraper replacement. Secondly, the distance between the two adjustment frames 31 is adjusted, and then the adjusted position of the adjustment frame 31 is stabilized by the threaded rod 37 and the threaded hole 36, thereby facilitating the placement of scrapers of different lengths.
