Description

Technical Field

[0001] The utility model relates to the technical field of composite particle processing, in particular to a granulator which is convenient for discharging. Background Art

[0002] Composite particles are particles that are made of multiple materials. A granulator is needed to process and produce composite particles. A granulator is a molding machine that can make materials into specific shapes.

[0003] For example, the utility model with application number CN202023257160.4 discloses an anti-adhesion plastic granule extrusion granulator. The utility model sets a driving motor to drive the connecting shaft and the spiral blade thereon to rotate, extrude the plastic, and sets a rotary motor to drive the blade to rotate to cut the plastic extruded from the inside of the outer shell. By distributing the blades at equal intervals, the plastic can be cut evenly to improve product quality. By setting a feed hopper, it is convenient to load the material. By setting a guide table, the cut plastic particles can be automatically moved to prevent blockage at the outlet. However, in the actual use of the device, when the blade is cutting the extruded material, due to the high temperature of the plastic after extrusion and a certain viscosity, part of the cut material may adhere to the blade, causing the subsequent material discharge and unloading to be affected.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved to provide a granulator that is easy to discharge. Utility Model Content

[0007] Furthermore, the blade is slidably connected to the die, and the blade is inclined.

[0008] Furthermore, the crankshaft is rotatably connected to the fixed frame, and the blades are equidistantly distributed around the outer side of the left end of the crankshaft.

[0009] Furthermore, the air jets are equidistantly distributed about the bottom of the diverter pipe, and the length of the diverter pipe is greater than the length of the die.

[0010] Furthermore, an anti-blocking component is provided at the upper right end of the fixed frame, and the anti-blocking component includes a filter cover and a diverter plate. The filter cover is placed on the right side of the fixed frame, and the diverter plate is fixed to the upper right end of the fixed frame.

[0011] Furthermore, the anti-blocking component also includes a through hole and a vent pipe. The bottom of the diverter plate is provided with a through hole, and the top of the diverter plate is connected to the vent pipe.

[0014] The utility model provides a granulator that is easy to discharge and has the following beneficial effects:

[0015] 1. The utility model sets an anti-sticking component. When the motor drives the crankshaft to rotate so that the blade cuts off the extruded material on the die, the crankshaft also drives the piston rod to move up and down reciprocatingly inside the piston cylinder through the connecting rod. When the piston rod moves down, the external air will be replenished into the piston cylinder through the one-way valve 1, and when the piston rod moves up, the internal airflow will pass through the one-way valve 2 and the fixed pipe and spray out from the spray head at the bottom of the shunt pipe to spray and clean the outer side of the blade, so as to avoid the adhesion of the material and affect the normal discharge of the material.

[0016] 2. The utility model provides an anti-blocking component. When external air is added to the inside of the piston cylinder through a one-way valve, the filter cover can be used to filter the air to prevent dust and impurities from clogging the nozzle and affecting its service life. At the same time, when the piston rod moves downward, the airflow at the lower part of the piston cylinder can be ejected from the through hole on the diverter plate through the ventilation pipe. Since the impact force of the airflow is relatively large, the outside of the filter cover can be automatically cleaned by jets to avoid clogging due to excessive impurities attached to the outside of the filter cover during long-term use.
