The sensing assembly 6 can monitor the bottle 3 in real time, avoid the contact between the scraper mechanism 5 and the printing mechanism 1 when there is no bottle 3 to be printed, avoid the occurrence of empty scraping, reduce the damage of the scraper mechanism 5 and the printing mechanism 1 due to the contact, and prolong the service life of the scraper mechanism 5 and the printing mechanism 1.

[0074] When the sensing assembly 6 detects the bottle 3 on the conveying belt 2, the scraper mechanism 5 moves downward to reciprocate in the vertical direction, so as to contact or separate from the printing mechanism 1; when the sensing assembly 6 detects that there is no bottle 3 on the conveying belt 2, the scraper mechanism 5 moves upward in the vertical direction and separates from the printing mechanism 1.

[0075] In some embodiments, the sensing assembly 6 comprises a sensor 61 and a sensing line 62, and the sensing line 62 connects the sensor 61 and the scraper mechanism 5.
