FOOD PATTY MOLDING MACHINE

摘要

The invention provides a patty-forming machine with many improvements. Th e machine includes a servo motor mold plate mechanism with improved swing li nks and reducer. The machine also includes a servomotor driven knockout appa ratus wherein the servomotor drives a cam and lever arrangement. A food syst em uses an integrated and compact motor and gearbox assemblies to drive the feed screws, and modular bearing assemblies on the shafts of the feed screws . The feed screws have heavy wall thickness flights. A sealed drum motor hou sed in the drive roller drives the hopper conveyor. The food system utilizes independent sensing means for indicating whenever the moldable food materia l accumulated at said one end of the hopper exceeds a given level. The cooli ng system with two fans and automatically closing dampers is improved and it s placement and arrangement within the machine is optimized to save space an d improve circulation. Linear displacement sensors are used in each hydrauli c power cylinder. The machine utilizes improve seals between mechanical comp artments and compartments in contact with food material. The machine provide s a swing out electrical enclosure and chassis and uses modular I/O blocks t o communicate between machine control and the solenoids.
