Problems solved by technology

[0002] To granulate or process plastic materials, it needs to be mixed first, then enter the extruder to extrude the molten material into strips or columns through a mold, and the plastic strips or columns coming out of the extruder need to be cooled by water to make them Hardening to facilitate the subsequent granulation or molding processes, but since the surface of the water-cooled strip or columnar plastic will inevitably stick or adhere to cooling water after passing through the water cooling device, this will affect the transportation of processed materials, Inconvenient to pack or store

[0003] Nowadays, the cooling and drying process of plastic extrusion molding generally adopts a combination of water-cooling device and air-cooling device. Among them, the air-cooling device mostly uses a blower, and the blower blows directly to the material so that the material is cooled while further drying the surface. The cooling water can be blown dry, and the wind can also be directed to the top of the extruded strips through a pipe, and then the strips are air-cooled from top to bottom. The above air-cooling methods are all from one direction Blow cooling air at a fixed point, which will not only cause the moisture around the strips to not be completely blown away, but also cause the surface of the extruded material to be affected by the wind force and uneven cooling, resulting in the wall of the extruded part The problem of uneven thickness or inconsistent mechanical properties of materials makes it difficult to guarantee the processing quality. At the same time, if multi-directional blowers are used in conjunction with multi-directional operations, it will lead to increased production costs and waste of energy.
