Technical Field
[0001] The utility model relates to the technical field of granulation devices, in particular to a resin extrusion granulation device. Background Art
[0002] Resin generally refers to an organic polymer that has a softening or melting range after being heated, has a tendency to flow under the action of external force when softened, is solid, semi-solid, or sometimes liquid at room temperature. In order to facilitate the transportation of the resin, the resin is usually processed into particles. In the granulation process of a traditional resin granulator, the crushed resin needs to be placed on a screw extruder for extrusion and discharge. For example, the patent with publication number CN217531465U discloses a resin powder granulator, including a screw extruder, one side of the screw extruder is provided with a power motor, the other side is provided with an extrusion discharge tray, and the top side of the screw extruder is provided with a resin conveying feed hopper. A fixed cross bar is fixedly installed on the resin conveying hopper, and a rotating crushing mechanism is installed on the fixed cross bar. Granulation and discharge are carried out through the extrusion discharge disc on the screw extruder. When discharging, the rotating motor is operated to drive multiple rotating knives to rotate, and the granulation of the extruded material is cut off, thereby forming granulated particles one by one, and falling into the collection bucket below for collection. However, in order to ensure that the resin can form particles in the prior art, the resin is usually heated to melt it and then cooled to shape it, which may cause a temperature difference on both sides of the extrusion discharge disc. If the resin solidifies due to the colder temperature, it will cause the extrusion discharge disc to be blocked, affecting the discharge rate.
[0003] To this end, the utility model provides a resin extrusion granulation device. Utility Model Content
