device for mixing and spreading of mehrkomponentenmassen.

摘要

A device for mixing and applying two-component materials, has two pistons 15, 16 which can be displaced in cartridges 12, 13 and which can be driven forwards together by an electric motor via a magnetic coupling 30, but which can be drawn back manually and inserted again via a manual wheel 33 when the motor is switched off and the magnetic coupling 30 moved out. At the end of the manual return movement, the pistons 15, 16 drive a shaft 18 which drives a mixing head 14 in rotation and which, simultaneously with the emergence of the pistons 15, 16 from the cartridges 12, 13, disengages with the mixing head 14. In this way, it is possible to remove the cartridges 12 and 13, together with the mixing head 14 connected thereto, out of the device as a unit and to replace them by another unit in order to change the spent cartridges or when the cartridges are still partially full to use the device in the interim to produce a different product. Despite the motor drive which is designed for a slow advance of the pistons 15, 16, such changing of the cartridges is quick and easy due to the manual extension and retraction of the pistons. …IMAGE…
