Underwater granulator for plastic

Abstract

The invention relates to the field of plastic particle processing equipment, in particular to an underwater granulator for plastic. The underwater granulator for the plastic comprises a rack, wherein a sliding seat is slidably connected to the rack, a shaft seat is arranged on the sliding seat, a core shaft is rotatably connected to the interior of the shaft seat, a spline is arranged at one end of the core shaft, a key sleeve sleeves the spline, a cutter is arranged at the end of the key sleeve, a first fixing ring is arranged on the key sleeve, a supporting plate for allowing the core shaft to penetrate therethrough is arranged on the side wall of the shaft seat, a second fixing ring is rotationally connected to the side wall of the supporting plate through a rotating part, a spring is connected between the second fixing ring and the first fixing ring, a driving motor used for driving the core shaft to rotate is arranged at the end, away from the cutter, of the shaft seat, a driving piece used for driving the sliding seat to move is arranged on the rack, a sealing cover right opposite to the cutter is arranged on the rack, a die head is arranged in the sealing cover, and a water inlet pipe, a water outlet pipe and a locking sealing piece are arranged on the sealing cover. The underwater granulator for the plastic has the effect of improving the particle forming quality.

Description

technical field [0001] The present application relates to the field of plastic granule processing equipment, in particular to a plastic underwater granulator. Background technique [0002] For low-viscosity, high-elastic polymer materials or granulation with special requirements for granulation, the molten rubber and plastic materials extruded through the die are usually cut into granules in flowing water by an underwater pelletizer. To get the best cutting effect, the cutter of the underwater pelletizer needs to keep in close contact with the die surface. [0003] In view of the related technologies mentioned above, the inventor believes that the conventional cutter is in hard contact with the end face of the die, which easily disturbs the cutter, thereby affecting the molding quality of the cut particles. Contents of the invention [0004] In order to improve the pellet forming quality, the application provides a plastic underwater pelletizer. [0005] A plastic underw...
