AI Technical Summary
Existing polyethylene granulation templates suffer from excessively fast airflow speeds and small channel contact areas, resulting in short residence times of hot air within the channels. This makes it difficult to achieve sufficient heat exchange with the material in the extrusion holes, affecting the molding time and molding effect.
A heat-conducting cavity and a baffle plate are set on the template body. The heat-conducting cavity is evenly distributed on both sides of the extrusion hole to increase the contact area, and the baffle plate reduces the flow rate of the high-temperature airflow to prolong the residence time and improve the heat exchange efficiency.
By increasing the contact area and extending the airflow residence time, the heating effect is improved, the material forming time is reduced, the forming effect is enhanced, and it is easier for staff to use.
