Abstract
A blowing device for a belt grinding machine has a nozzle arrangement having nozzles positioned relative to its grinding belt for blowing cleaning air jets onto the circulating grinding belt. The device further has an oscillating drive to oscillate the nozzle arrangement in the longitudinal direction thereof. A pair of elastic members suspend the nozzle arrangement, which is oscillated in the longitudinal direction by using a magnetic field. A ferromagnetic member is connected to the nozzle arrangement and is positioned within the magnetic field produced by an electric coil. By varying the magnetic field, the nozzle arrangement can be moved in the longitudinal direction, the spring providing an elastic restoring force to move the nozzle arrangement is the opposite direction when the magnetic field is turned off.
Claims20
A blowing device for a belt grinding machine, comprising:
- a nozzle arrangement adapted to be positioned relative to a grinding belt of the grinding machine, wherein the nozzle arrangement is adapted to provide cleaning air jets onto the grinding belt;
- and
- a driver for oscillating the nozzle arrangement along a longitudinal direction of the nozzle arrangement, the driver comprising:
- a mount for holding and guiding the nozzle arrangement in the longitudinal direction;
- and
- a ferromagnetic member connected to the nozzle arrangement;
- a magnetic field generator for generating a magnetic field, wherein the ferromagnetic member is positioned adjacent the magnetic field generator and is moved by varying the magnetic field, the nozzle arrangement being moved along the longitudinal direction by moving the ferromagnetic member.
A blowing device for a belt grinding machine, comprising:
- a nozzle arrangement adapted to be positioned relative to a grinding belt of the grinding machine, wherein the nozzle arrangement is adapted to provide cleaning air jets onto the grinding belt;
- and
- a driver for oscillating the nozzle arrangement along a longitudinal direction of the nozzle arrangement, the driver comprising:
- means for suspending the nozzle arrangement, which means enables the nozzle arrangement to move along the longitudinal direction;
- and
- means for pulling or pushing the nozzle arrangement in the longitudinal direction using a magnetic field.
