The invention discloses an
underwater granulator for low-melting-point
hot melt adhesives. The
underwater granulator comprises a
workbench. An
extrusion device is fixedly installed on one side of the top surface of the
workbench, a granulating chamber is fixed to one side of the
extrusion device, and a U-shaped plate moving in the horizontal direction is arranged on the other side of the top surface of the
workbench. A first motor is fixedly installed at the center position of the side, close to the granulating chamber, of the U-shaped plate, a rotating rod is fixedly installed on an output shaft of the first motor, a fixing block is fixedly installed at one end of the rotating rod, and a fixing plate is connected to the fixing block in a clamped mode. According to the
underwater granulator for the low-melting-point
hot melt adhesives, the fixing block, the fixing plate, a fixing groove, clamping grooves, side grooves, second motors, first lead screws, clamping blocks, mounting blocks, through holes, mounting holes, an
insertion groove and screws are arranged, independent disassembly and fixation of a cutter head or blades can be completed, and therefore when the cutter head or the blades are damaged, the cutter head or the blades can be conveniently, independently and quickly disassembled and maintained or replaced, and the waste of the whole cutter head and blade materials is avoided.
