20090101235 | FEEDING MECHANISM FOR A WOODWORKING MACHINE - A feeding mechanism adapted for use with a woodworking machine includes a driving unit and a feeding roller unit. The feeding roller unit includes a driven shaft that extends along an axis from the driving unit and that is driven by the driving unit to rotate about the axis, a feeding roller that is disposed co-rotatably around the driven shaft, a plurality of contact components, and a plurality of resilient components. Each of the contact components has a contact end portion and is resiliently movable relative to the feeding roller between an extended position, where the contact end portion is exposed from the feeding roller, and a retracted position, where the contact end portion is retracted into the feeding roller. Each of the resilient components is disposed for biasing a respective one of the contact components toward the extended position. | 04-23-2009 |
20090133779 | FEEDING MECHANSIM FOR A WOODWORKING MACHINE - A feeding mechanism is adapted for use with a woodworking machine. The feeding mechanism includes a rail unit adapted to be disposed on two sides of a worktable, a feeding unit, and a press roller unit. The feeding unit includes a slidable body adapted to extend across the worktable and disposed slidably on the rail unit, two spaced apart rollers disposed on the slidable body, a belt component trained on the rollers, and a driving component for driving the rollers to rotate along with the belt component. The press roller unit is adapted to extend slidably across the worktable and includes a slidable seat disposed slidably on the rail unit, a press roller connected pivotally to the slidable seat, and a resilient component adapted for biasing the press roller to press the workpiece against the feeding unit. | 05-28-2009 |
20100175789 | Floating Caterpillar Feeder - A floating caterpillar feeder is used for moving a workpiece on a worktable. The feeder includes a housing unit having a bottom edge, a driving unit including two pairs of sprockets and two chains respectively trained on the pairs of the sprockets, and a plurality of feeding units connected between the chains. Each feeding unit includes two mounting members connected respectively and fixedly to two corresponding links of the chains, parallel horizontal inner and outer rods connected fixedly between the mounting members, parallel pushing plates sleeved on the inner and outer rods, and resilient members for biasing the pushing plates to project from the bottom edge. Each pushing plate has a pair of inner and outer holes engaging respectively and movably the inner and outer rods so as to allow the corresponding pushing plate to move relative to the inner and outer rods in an inner-to-outer direction. | 07-15-2010 |
20110088815 | ROTARY TYPE FEEDING DEVICE FOR WOODWORKING MACHINE - A rotary type feeding device for a woodworking machine includes a support post unit including a base adapted to be mounted on a worktable, and a pivot shaft disposed uprightly on the base. A cantilever unit includes a cantilever rotatable about the pivot shaft and having a pivot end proximate to the pivot shaft, and a free end distal from the pivot shaft, and a return member. A feeding wheel unit includes a feeding wheel disposed pivotally on the free end of the cantilever. The feeding wheel has a diameter that is not smaller than 250 mm. The return member of the cantilever unit is adapted for biasing the feeding wheel of the feeding wheel unit to pivot toward a cutter. | 04-21-2011 |
20120097003 | ROTARY TYPE FEEDING DEVICE FOR A WOODWORKING MACHINE - A rotary type feeding device for a woodworking machine includes a support post unit, a cantilever unit, and a feeding wheel unit. The support post unit includes a base fixed on a worktable, and an upright pivot shaft fixed on the base. The cantilever unit includes a cantilever rotatable about the pivot shaft, and a return member disposed between the support post unit and the cantilever for biasing the cantilever to pivot toward a cutter. The feeding wheel unit includes a mounting seat disposed on a free end of the cantilever, and a plurality of feeding wheels disposed rotatably on the mounting seat. A reference line is defined to extend through a contact surface of the fence member and a top surface of the worktable. Outer peripheries of the feeding wheels are spaced apart from the reference line by different distances. | 04-26-2012 |
