Patent ID: 6991145

Claim:
A synchronous fine tunable feeding mechanism comprising: a platform including a first side panel, a second side panel, a top panel disposed on said first and second side panels, a fixed roller pivotally coupled between said first and second side panels and a movable roller contacting said fixed roller; two control members being disposed at said top panel and elastically pushing against said movable roller; and a link device being disposed between said two control members for simultaneously driving one of said control members according to the movement of another one of said control members to synchronize said two control members to elastically push said movable roller; wherein said movable roller maintains a constant pressure with respect to said fixed roller as to exert an even force onto a work piece clamped by contact surfaces of said movable roller and said fixed roller, wherein said link device comprises two active components, a passive component and two bases, and said two active components are coupled to said two control members respectively and said passive component is coupled between said two active components for generating a synchronous movement, and said two bases are secured on one side of said top panel for fixing said two active components at appropriate positions.
