Abstract
A spiral cutting device includes a blade, a blade driving shaft, a guiding device, a driving device, and a controller. The blade is for processing a roller. The blade driving shaft drives the blade to move toward the roller. The guiding device moves in a guiding direction perpendicular to a moving direction of the blade. The driving device is movably supported on the guiding device and rotates the roller. The controller controls a feeding amount of the blade, a moving speed of the driving device, and a rotate speed of the roller to spirally cut the roller. When an outer surface of the roller is unfolded to a plane, the blade path of the blade is in sinusoidal shape or in cosinusoidal shape.
Claims4
A spiral cutting device configured for processing a roller, comprising:
- a blade for processing the roller;
- a blade driving shaft holding the blade and configured for driving the blade to move in a moving direction;
- a guiding device capable of moving in a guiding direction perpendicular to the moving direction of the blade;
- a driving device movably supported on the guiding device and configured for rotating the roller, the driving device comprises a lower plate and two supporting arms extending upward from two opposite edges of the lower plate, the lower plate is supported on the guiding device, and the two supporting arms are configured for rotatably holding the roller;
- and
- a controller in communication with the blade driving shaft, the guiding device, and the driving device and configured for controlling a feeding amount of the blade, a moving speed of the driving device, and a rotate speed of the roller to spirally cut the roller;
- wherein when an outer surface of the roller is unfolded to a plane, a blade path of the blade is in sinusoidal shape or in cosinusoidal shape.
