Underwater granulator for low-melting-point hot melt adhesives

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of underwater pelletizers, in particular to an underwater pelletizer for low melting point hot melt adhesives. Background technique [0002] Hot melt adhesive is a kind of plastic adhesive. Its physical state changes with temperature within a certain temperature range, but its chemical properties remain unchanged. It is non-toxic and tasteless. It is an environmentally friendly chemical product because the product itself is solid. Convenient for packaging, transportation, storage, solvent-free, non-polluting, non-toxic, and simple production process, high value-added, strong bonding strength, fast speed and other advantages; [0003] Hot melt adhesive needs to use pelletizer in the process of production and processing. Underwater pelletizer is a new type of processing machinery for semi-finished polymer polymers. Because its cutting process is carried out in water, it is named after it. Now it is Some under...

Problems solved by technology

[0003] Hot melt adhesive needs to use pelletizer in the process of production and processing. Underwater pelletizer is a new type of processing machinery for semi-finished polymer polymers. Because its cutting process is carried out in water, it is named after it. Now it is Some underwater granulator blades and cutterheads are generally fixed and welded. When one of them is damaged, it cannot be disassembled and replaced separately, which easily causes waste of material resources.
