Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic production, in particular to a plastic extrusion granulation production device. Background Art
[0002] Plastic slitting and granulation is an important part of the plastics industry, which involves the process of converting waste plastics or bulk plastic materials into small granular plastic materials. These granular materials can be further used to manufacture various plastic products, thus achieving effective reuse of resources.
[0003] At present, plastic processing generally adopts plastic extrusion, cooling and pelletizing processes. The plastic is melted under heating and pressure through the joint action of the screw and the die, and is extruded through a die mouth of a specific shape to form a continuous profile. After extrusion molding, the temperature of the plastic product is quickly reduced to fix its shape and prevent deformation. Finally, the extruded plastic profile is cut into granules for subsequent processing, storage and transportation. In the traditional plastic production process, plastic pelletizing and cooling are generally carried out separately, which leads to the need to equip the production line with cooling equipment and pelletizing equipment at the same time. There are many disadvantages such as scattered equipment, large space occupied, and high equipment cost. In view of this, the present application proposes a plastic extrusion granulation production device. Utility Model Content
