Spindle Moulder Adjustment

What follows was one of the key when I made the decision for that combination machine rather than another one. All the needed elements to use the spindle moulder stand just underneath the shaft and doesn't require the operator to move other than slightly leaning to open the front door. Spindle lock and vernier gauge as well as belt switching are within arm reach and as soon as the door opens a micro-switch breaks the circuit preventing any unexpected motor start. As matter of interest I sometimes forgot to remove the rod keeping the spindle at a standstill before starting on previous machines. This can no longer happen since that mechanism is behind the door and the rod in lock place does not allow the door to be closed.

Overview


The right hand wheel drives the lift mechanism and the left lock knob prevent the spindle from rising or lowering. The micro-adjustment device freely rotates in the wheel and enables for all relative moves. First I line up the zero with the water level then pivot both wheel and vernier up to the wished adjustment. Forty seven sections of one tenth of a millimetre provide 4.7mm per rotation.

Micro Adjustment


I always use the rod to block the spindle before replacing cutter heads that results in breaking the electrical circuit and the spindle moulder can only start after closing the door which means the rod to be put away along the internal face of that door.

Shaft Lock


That same rod also provides a means of loosening the transmission and shifting the belt amongst three positions for speed range or torque as you wish : 4200, 6750 and 8500 rotations per minute. Besides I connected a variable frequency drive that enables for dynamically adjust the speed from 1500 to 8500 rpm.
