[0020] The adaptive swing seat 3 is formed with a mounting groove 31, in which a mounting rod 5 is inserted along the front-to-back direction. A joint bearing 7 is provided at one end of the support rod 2 away from the mounting seat 1 and is sleeved on the mounting rod 5 through the joint bearing 7. Elastic limit members 6 are respectively sandwiched between the front end of the support rod 2 and the front wall of the mounting groove 31, and between the rear end of the support rod 2 and the rear wall of the mounting groove 31. Since the elastic limit member 6 has a certain elasticity, there is a certain swing space between the adaptive swing seat 3 and the support rod 2. By cooperating with the joint bearing 7, the scraper 43 can achieve front and rear adaptive adjustment when encountering different heights of the front and rear ends of the plate.

[0021] The elastic limiting member 6 in this embodiment is a rubber pad. Of course, in other embodiments, the elastic limiting member 6 can also be other components such as a spring.

[0022] The scraper module 4 includes a mounting block 41, an adjusting column 42 slidably connected to the mounting block 41 in the vertical direction, a scraper 43 arranged on the adjusting column 42, an adjusting bolt 44 arranged on the top of the mounting block 41, and a stopper 45 arranged on the front end of the mounting block 41.

[0027] Working principle:

[0028] The plates to be scraped with glue are conveyed through the utility model in turn. As the plates move, the scraper 43 in the scraper module 4 of the utility model scrapes away the residual glue on the surface of the plates. When the front and rear ends of the plates to be scraped are at different heights, the plates will push the scraper 43 forward and upward or rearward and upward, and the adaptive swing seat 3 will swing forward and upward or rearward and upward accordingly, and the blade position of the scraper 43 will swing forward and upward or rearward and upward adaptively, thereby realizing the front and rear adaptive adjustment of the scraper 43. The scraper 43 of the utility model can automatically perform front and rear adaptive adjustment. Even when scraping glue on plates with different front and rear ends, the blade of the scraper 43 can always fit the surface of the plate and only scrape away the residual glue on the surface of the plate without scraping the plate itself. The residual glue on the surface of the plate can be well removed while ensuring that the plate will not be damaged.

[0029] Of course, the above is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
