[0002] PVC is a polymer formed by the polymerization of vinyl chloride monomers through a free radical polymerization mechanism under the action of an initiator or light or heat. PVC was once the world's largest-volume general-purpose plastic and is still widely used in building materials, industrial products, daily necessities, floor coverings, pipes and other fields. In the production process of PVC granules, since the temperature of PVC is high when it reaches a viscous flow state, it needs to be cooled after extrusion before subsequent packaging. Traditionally, water cooling is often used for cooling, that is, the extruded PVC strips are introduced into cooling water, cooled by cooling water, dried and cut into granules, and finally the finished PVC granules are obtained.

[0003] When the existing water-cooling structure is used, there is no suitable collecting device, so the PVC pellets after cooling have no suitable collection method. After the PVC pellets are taken out, they are all mixed together and very wet. If they are not dried in time, they will be soaked in water for a long time, which will affect the material of the PVC pellets, and it is impossible to distinguish good PVC pellets from bad PVC pellets. In addition, since the volume of PVC pellets is very small, it is very difficult to salvage them after water cooling, and it is very time-consuming and laborious to unload them.
