DRIVING DEVICE OF A METERING AND MIXING APPARATUS

摘要

A driving device of a metering and mixing apparatus for multi-component substances is disclosed, which driving device has at least two cartridge holders for holding interchangeable cartridges, a discharging apparatus for the simultaneous discharging of the substance components from the cartridges by discharging pistons entering the cartridge holder or cartridges, where at least one discharging piston has a thread which can generate a forward propulsion of the discharging piston, and a mixing apparatus for discharging the substance components in mixed form. A transmission unit connects a drive motor, and a spindle-like discharging rod of the discharging piston is provided with the thread, a rear part of the longitudinal extent of which discharging rod has a spiral-toothed, non-self-locking spindle section, and at a front end of which has an engagement element for engaging in the discharging piston.

主权项

1. A driving device of a metering and mixing apparatus for multi-component substances, the driving device comprising:
at least two cartridge holders configured to hold replaceable cartridges with individual substance components; a discharging device configured to simultaneous discharge the substance components from cartridges through component outlets with aid of discharging pistons for entering the cartridge holder or cartridges, wherein at least one discharge piston has a threading which will produce forward propulsion of the at least one discharge piston by rotation; a mixing apparatus connected to the component outlets for mixing the discharged substance components and discharging them in mixed form; a spindle-like discharging rod of the at least one discharging piston provided with the threading, which in a rear part has a spiral-toothed spindle section and at a front end has an engagement element for engaging in the at least one discharging piston; and a transmission unit for connection of a drive motor, wherein the transmission unit has an internally toothed driven wheel which is matched to the spiral toothing of the spindle section.
