[0032] The collection box 9 is designed to facilitate the collection of excess coating liquid. The insertion rod 11 is designed to prevent the collection box 9 from sliding on the support plate 1. By lifting the insertion rod 11 and holding the two handles 10, the collection box 9 can be removed from the support plate 1.

[0033] To remove and replace the scraper 7, simply pull down the two pull blocks 16. The two pull blocks 16 will cause the two insert blocks 15 to move down, and the two springs 17 will be compressed and contracted. The tops of the two insert blocks 15 will come out of the slots at the bottom of the two stops 14. Rotating the cover 12 will release the restriction on the scraper 7, making it easy to remove and replace the scraper 7.

[0034] During installation, the top of the scraper 7 is placed in the blade holder 4, and the two positioning pins 40 pass through the two through slots on the scraper 7. After the pressure cover 12 is put on, the two pull blocks 16 are released. During the reset process of the two springs 17, the two insert blocks 15 are pushed upward. The tops of the two insert blocks 15 are inserted into the slots at the bottom of the two stops 14, which can prevent the pressure cover 12 from moving, thus facilitating the installation of the scraper 7.
