Embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
The roller group for silicon wafer wool making of the utility model, make pressure ring on roller and silicon chip contact area replaces change
Change, so that the response difference caused by rolling wheel stamp is solved the problems, such as, to obtain preferable making herbs into wool effect.Below by specific embodiment
Illustrate the structure for the roller group that refreshing utility model provides.
Embodiment one
As shown in Figures 1 to 3, a kind of roller group for silicon wafer wool making, by taking two adjacent rollers as an example, two rollers wrap
Include the roller bodies 10 of tubulose, two pressure rings 11 for being used to contact with silicon chip, phase are circumferentially with along it on 10 outer wall of roller bodies
Pressure ring 11 in adjacent two roller bodies 10 mutually staggers, i.e. two pressure rings 11 difference position in one of roller bodies 10
In the not homonymy of two pressure rings in another roller bodies.
Further, pressure ring 11 and the material of roller bodies 10 are PVDF, are made up of integrally formed, cost is low, and resistance to
Burn into service life is grown, easy processing manufacture.
When roller is used for making herbs into wool, roller bodies 10 are through on carbon-point 15, drive roller to rotate by gear 12.Specifically
Multiple card slots 14 for being used to block teeth 13 on gear 12 can be uniformly arranged on the end of roller bodies 10.Pass through the side of engagement
Formula, rotates roller.During making herbs into wool, silicon chip is driven when being run in machine by roller, both rollers are staggered successively, are made
