[0026] Example 2

[0027] like Figure 1-3 As shown, a papermaking glue scraping mechanism proposed by the utility model, compared with embodiment 1, this embodiment also includes a glue collecting mechanism including a conduit 13, the conduit 13 is located at the bottom of the glue collecting box 6, the bottom outer ring of the conduit 13 is rotatably connected to a glue collecting bottle 14, a support plate 18 is welded to the outer side of the right side plate of the device frame 1, a motor 2 is installed on the top of the support plate 18, the output end of the motor 2 is fixedly connected to a center column 3, the two center columns 3 both penetrate the left and right side walls of the device frame 1, a center column 3 is fixedly sleeved with a glue rolling roller 4 on the outer ring, and the other center column 3 is fixedly sleeved with a glue rolling roller 4 on the outer ring. The outer ring of a central column 3 is rotatably connected to the inner ring of another rubber rolling roller 4, two clamps 10 are welded to the outer walls on the left and right sides of the device frame 1, and a two-way screw rod 9 is rotatably sleeved on the two clamps 10 and the inner rings of the two connecting plates 7. A moving handle 8 is welded to the end of the two-way screw rod 9 away from the clamp 10, and a mounting frame 15 is provided on the outer walls on the left and right sides of the device frame 1. A fan 16 is installed on the inner side of the mounting frame 15, and the fan 16 is fixed with fan blades 17 through a rotating shaft. Universal wheels 20 are fixedly installed at the four corners of the bottom of the device frame 1 through hinged seats.

[0028] In this embodiment, the glue collecting mechanism includes a conduit 13, which is located at the bottom of the glue collecting box 6.

After the front end of the cardboard is passed through, the moving handle 8 is adjusted and rotated, and the two-way screw rod 9 is driven to rotate by the moving handle 8. When the two-way screw rod 9 rotates, the two connecting plates 7 can be moved away or closer. When the two connecting plates 7 are adjusted to a suitable use distance, the two scraper plates 5 can contact the two sides of the paper. When the two connecting plates 7 are close, the two scraper plates 5 are close. When the two scraper plates 5 are mutually When the two glue collecting boxes 6 and the glue collecting mechanism are close, they will also move closer to determine the appropriate position.
