[0009] As a further improvement, at least two sliders are provided at each end of the scraper, one end of the adjusting screw is threadedly connected to one of the sliders, and one end of the adjusting screw is through-connected to the remaining sliders.

[0010] Furthermore, the thickness of the scraper is 3 mm to 5 mm, and the width of the scraper is adapted to the width of the roller.

[0011] Furthermore, a cleaning knife is provided on one side of the scraper, the side of the cleaning knife is attached to the side of the scraper, and a trigger mechanism that can drive the cleaning knife to reciprocate up and down is provided on one side of the scraper.

[0013] Furthermore, the cleaning knife is an L-shaped knife with a pointed structure at the bottom.

[0014] Beneficial Effects

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] 1. The utility model provides a scraper device for sintering round rollers. By arranging a scraper above the round roller, when the round roller rotates and the sticky material on its surface is higher than the gap between the scraper and the round roller, the sticky material can be automatically cleaned during the rotation of the round roller without manual cleaning of the sticky material, which effectively reduces labor intensity and improves production efficiency. Moreover, the height of the scraper relative to the round roller can be adjusted by adjusting the screw to achieve online adjustment of the gap, ensuring that the sticky material on the round roller is within a controllable range, which is more convenient to use.

[0017] 2. The sintered roller scraper device of the utility model is provided with a cleaning knife on one side of the scraper. After being used for a period of time, the cleaning knife can be driven downward by pushing the pull rod to cut off the sticky material adhering to the scraper. Since the cleaning knife is connected to the mounting plate by a spring, the cleaning knife can reciprocate and clean the sticky material on the scraper, which is convenient for observing the distance between the scraper and the roller, and also convenient for observing whether the bottom of the scraper is damaged, which is convenient for subsequent maintenance.
