Technical Field
The utility model relates to the technical field of granulator, in particular to a cyclone cooling structure in the process of granulating medical PVC plastic.
Background
Plastic pelleting is a process of plastic machining, and plastic pelleting machine equipment mainly comprises a preheating device, a cooling device and an extruder. The extrusion unit uses different auxiliary equipment for its matching. Such as a granulator, dryer, etc.
PVC material in a molten state extruded by the existing extruder is cut into particles by using a blade of a granulator after being shaped by a die discharge plate, the blade needs to be clung to the plane of the discharge plate, a gap cannot be formed between the blade and the plane, otherwise, burrs and flying chips are formed on the particles, or the particles are attached to the surface of the PVC material to influence the appearance of the PVC material, as shown in figure 1, the existing tool rest surface A is too far away from the side surface of the installed blade, so that the PVC material cannot be positioned, and a gap of 5mm is formed between the blade and the blade. The other two cutting edges are not collinear, the plane where the two cutting edges are positioned is parallel to the plane of the discharging plate, and the operation and adjustment difficulty is high. When the blade is installed and replaced, the position of the blade needs to be adjusted repeatedly, once the blade is slightly uneven with the tool rest surface A, a gap is formed between the blade and the plane of the discharging plate, so that cut aggregate has flash, and poor product quality is caused.
