Description

利用废PVC生产PVC片材的挤压机
技术领域
本实用新型涉及PVC生产领域,具体涉及一种利用废PVC生产PVC片材的挤压机。
背景技术
在传统的PVC生产工艺流程中,经过密炼机对原材料进行混炼之后,从密炼机的出料口排出,转运至下一道工序,进入开炼机制备塑炼胶、混炼胶或进行热炼、出型。经过长期的生产发现,通过开炼机进行PVC片材的热炼,其拉力系数和材料密度往往都达不到理想的指标,究其原因是因为开炼机的机械结构特征,使密炼之后的原料无法得到更充分的糅合、挤压,最终影响成品的产品性能指标。
实用新型内容
针对以上现有技术中存在的问题,本实用新型提供了一种挤压充分、产品性能好的利用废PVC生产PVC片材的挤压机。
本实用新型是通过以下技术方案实现的:
利用废PVC生产PVC片材的挤压机,所述挤压机包括加料装置、传动机构、螺杆、螺套以及模头,所述螺杆为锥形螺杆。
所述螺杆上设有螺纹,所述近加料装置一端的螺纹直径大于螺杆一端的螺纹直径。
本实用新型的有益效果为:摒弃了现有技术中糅合、挤压不充分,影响产品性能指标的开炼机,选用挤压机对经过密炼的原材料进行糅合、挤压,利用螺杆和螺纹的推进式配合,对材料进行更为充分的挤压和糅合,经过挤压机处理的材料,其拉力系数和材料密度都远高于经过开炼机处理的材料,因而能获得性能指标高的产品。
附图说明
图1为本实用新型的结构示意图。
图中:1为加料装置;2为传动机构;3为螺杆;4为螺套;5为模头;6为螺纹。
具体实施方式
以下结合附图和具体实施方式对本实用新型做进一步详细说明。
本实用新型提供了一种利用废PVC生产PVC片材的挤压机,包括加料装置1、传动机构2、螺杆3、螺套4以及模头5,其中螺杆3为锥形螺杆,螺杆3上设有螺纹6,近加料装置1一端的螺纹直径大于模头5一端的螺纹直径。
本实用新摒弃了现有技术中糅合、挤压不充分,影响产品性能指标的开炼机,选用挤压机对经过密炼的原材料进行糅合、挤压,利用螺杆和螺纹的推进式配合,对材料进行更为充分的挤压和糅合,经过挤压机处理的材料,其拉力系数和材料密度都远高于经过开炼机处理的材料,因而能获得性能指标高的产品。
