| 摘要 |
The invention concerns equipment for feeding materials into plastics-processing machines. The equipment consists of a large number of modules which can be put together interchangeably to form the following assemblies: a first assembly, comprising a vacuum-feed device (10; 20, 20') connected on the output side to a funnel (30') which is connected to the plastics-processing machine (70) either directly, or indirectly via a mixer head (50') which can be connected to another assembly; a second assembly, comprising a vacuum-feed device (10; 20, 20') connected on the output side via a funnel (30) to a metering device (40) which is connected to the plastics-processing machine (70) via a mixer (50) which can be connected to at least one other assembly; a third assembly, comprising a storage bin (35, 40'), for granular, powder or liquid ingredients, and, connected to the output side of the storage bin, a metering device (40, 40') which is connected to the plastics-processing machine (70) via a mixer (50) which can be connected to at least one other assembly. The drive, measurement and control equipment of the modules in all the assemblies is powered by a low-voltage d.c. supply from a central power-supply unit using wire-free connectors. |
