Description

Technical Field

[0001] The invention relates to the technical field of plastic processing, in particular to equipment for drying, plasticizing and integrated injection molding processing. Background Art

[0002] The drying and plasticizing integrated injection molding equipment is a device that integrates the drying and plasticizing processes of plastic raw materials, which can improve production efficiency, ensure product quality and reduce energy consumption. It is usually necessary to put the plastic granule raw materials into the drying hopper. Under the action of heating and hot air circulation, the moisture in the raw materials is removed, and the dried raw materials enter the barrel. Plasticization is carried out in the barrel by heating and rotation of the screw, and finally injected into the mold for molding. The commonly used plastic granule hopper dryer has different specifications and sizes of plastic thermoplastic particles. They are piled up and squeezed against each other in the drying bin to form a relatively tight structure. It is difficult for hot air to enter the gaps between the particles, so that the temperature of the outer plastic particles rises quickly and the temperature of the inner plastic particles rises slowly, which leads to uneven drying effect of the overall particles, affecting product quality. Secondly, during the drying process, the cone net at the bottom of the hopper will adhere to dust particles on the surface of the cone net due to the action of airflow and electrostatic adsorption, blocking the cone net. The hot air flow will increase the local temperature at the blockage of the cone net, thereby causing the plastic particles to agglomerate, thereby affecting the injection molding efficiency. In view of the above problems, the inventor proposes a drying and plasticizing integrated injection molding equipment to solve the above problems. Summary of the invention
