Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Examples
A scraper structure of a dry granulator is shown in figures 1-4 and comprises an upper press roll 1, a lower press roll 2, an upper scraper 3 and a lower scraper 4; an upper scraper 3 and a lower scraper 4 are respectively arranged on one side of the upper compression roller 1 and one side of the lower compression roller 2; the upper scraper 3 and the lower scraper 4 are both provided with a circular shaft hole 8 and an elliptical shaft hole 9, and the elliptical shaft hole 9 is provided with an adjusting shaft sleeve 7; the fixing shafts 5 are arranged in the circular shaft hole 8 and the elliptical shaft hole 9, and the fixing shafts 5 are locked through locking nuts 6 and used for fixing the upper scraper 3 and the lower scraper 4; one side of the upper scraper 3 close to the upper compression roller 1 is provided with an upper scraper main front angle 31, and an upper scraper limiting plane 32 which can be tangent with the upper compression roller 1 is arranged at the upper scraper main front angle 31; one side of the lower scraper 4 close to the upper compression roller 2 is provided with a lower scraper main front angle 41, and a lower scraper limiting plane 42 which can be tangent with the lower compression roller 2 is arranged at the lower scraper main front angle 41. An upper scraper rear angle 33 is arranged on one side of the upper scraper 3 close to the upper compression roller 1, and an arc notch is arranged between the upper scraper rear angle 33 and the upper scraper front angle 31; one side of the lower scraper 4 close to the lower press roller 2 is provided with a lower scraper back angle 43, and an arc notch is arranged between the lower scraper back angle 43 and the lower scraper front angle 41. An upper scraper minor front angle 34 is arranged on one side of the upper scraper 3 far away from the upper compression roller 1, an arc-shaped notch is arranged between the upper scraper minor front angle 34 and the upper compression roller major front angle 31, and the position of the upper scraper minor front angle 34 is lower than the upper scraper major front angle 31.
