Wheel for feeding sheet members and feed roller using the same

Abstract

A wheel for a feed roller for feeding sheet members includes an annular wheel body and a plurality of protrusions protruded from a circumferential periphery of the annular wheel body. The present invention is also to provide a feed roller for feeding sheet members, which use the wheels. The feed roller includes a shaft and the wheels, which are coaxially sleeved onto the shaft and closely abutted with one another.

1 . A wheel for a feed roller for feeding sheet members, said wheel comprising: 
 a circular wheel body; and    a plurality of protrusions protruded from a circumferential periphery of said circular wheel body.    
   
   
       2 . The wheel as claimed in  claim 1 , wherein said protrusions are equiangularly spaced around the circumferential periphery of said circular wheel body.  
   
   
       3 . The wheel as claimed in  claim 1 , wherein said circular wheel body has a center axle hole.  
   
   
       4 . The wheel as claimed in  claim 1 , wherein said circular wheel body has a mounting through hole.  
   
   
       5 . The wheel as claimed in  claim 1 , wherein said protrusions have a cylindrical shape.  
   
   
       6 . The wheel as claimed in  claim 1 , wherein said protrusions have a conical shape.  
   
   
       7 . A feed roller for feeding sheet members, comprising: 
 a plurality of circular wheels coaxially arranged relative one another;    wherein said wheels each have a circular wheel body and a plurality of protrusions protruded from a circumferential periphery of said circular wheel body.    
   
   
       8 . The feed roller as claimed in  claim 7 , wherein said circular wheel body has a center axle hole.  
   
   
       9 . The feed roller as claimed in  claim 7 , wherein said circular wheel body has a mounting through hole.  
   
   
       10 . The feed roller as claimed in  claim 7 , wherein said protrusions of said wheel have a cylindrical shape.  
   
   
       11 . The feed roller as claimed in  claim 7 , wherein said protrusions of said wheel have a conical shape.  
   
   
       12 . The feed roller as claimed in  claim 8 , further comprising a shaft inserted into the center axle holes of said wheel bodies of said wheels.  
   
   
       13 . The feed roller as claimed in  claim 12 , further comprising a bushing sleeved onto said shaft.  
   
   
       14 . A feed roller for feeding sheet members, comprising: 
 a shaft; and    a plurality of wheels each having an annular wheel body coaxially sleeved onto said shaft, and a plurality of protrusions protruded from a circumferential periphery of said annular wheel body.    
   
   
       15 . The feed roller as claimed in  claim 14 , wherein the wheels are abutted with one another.  
   
   
       16 . The feed roller as claimed in  claim 14 , further comprising a bushing sleeved onto the shaft to separate said wheels into two sets at two sides of said bushing.  
   
   
       17 . The feed roller as claimed in  claim 14 , wherein said wheel body of said wheels each have a mounting through hole through which a fastening rod is firmly inserted.
