Abstract
The application relates to a doctoring unit for a printing apparatus for printing flat substrates, in particular circuit boards, wafers, or solar cells, comprising two doctor blades, which extend parallel to one another and are pivotably mounted. It is provided that the doctor blades are operatively connected to a gearing, which is formed in a self-locking manner and can be coupled or is coupled to a drive device.
Claims18
A doctoring unit for a printing apparatus for printing flat substrates, comprising two doctor blades, which extend parallel to one another and are pivotably mounted, wherein the doctor blades are operatively connected to a gearing and by means of the gearing, which is formed in a self-locking manner as worm gearing and can be coupled or is coupled to a drive device, wherein the gearing has a drive shaft, which, on the one hand, is coupled to a worm shaft and which, on the other hand, has a coupling end, which is formed for releasably coupling the drive shaft to the drive device.
A doctoring unit for a printing apparatus for printing flat substrates, comprising two doctor blades, which extend parallel to one another and are pivotably mounted, wherein the doctor blades are operatively connected to a gearing and by means of the gearing, which is formed in a self-locking manner as worm gearing and can be coupled or is coupled to a drive device,
- wherein the drive device has a doctoring unit holder, which can be releasably connected to the doctoring unit,
- wherein a controllable actuator for pivoting the doctoring unit holder is assigned to the doctoring unit holder on at least one protrusion, which is spaced apart from a center axis, and
- wherein the actuator is formed as a pneumatic actuator comprising a lifting piston, which is assigned to said at least one protrusion and which can be displaced tangentially to the center axis.
