瓶盖机的圆周面旋转式多压力油路机构
本专利技术涉及瓶盖机,特别是涉及瓶盖机的圆周面旋转式多压力油路机构。
技术介绍
用于制造矿泉水瓶和油瓶等瓶盖的设备,在成型过程中包括挤塑机构、模压机构、切环机构和折边机构等,由挤塑机构挤出热熔的胶料经刮料机构将挤出料送到模压机构的模具中,经模压成型的瓶盖经脱模装置从上模中脱出。其中模压机构包括上模板和下模板,上模板中设置定模,下模板中设置油缸,油缸上设置动模,当热融的塑料落到动模上后,由油缸带动动模向上与定模合模,从而得到模压成型的瓶盖。已有模压机构中的油缸通过设置换向阀进行油压的换向,实现高压油路和回油油路的换向(即下模要向上合模时,油缸下腔中通入8MPa的高压油液,油缸的上腔回油,高压油液推动活塞杆向上移动,使模具合模;当下模要向下开模时,通过换向阀对油压进行换向,使油缸的下腔回油,油缸的上腔通入8MPa的高压油液,使模具开模),该结构的油压变换单一,在合模或开模时直接通入8MPa的高压油液,压力高,导致油缸以及模具开合模动作的冲击力大,使用寿命短,合模动作产生的噪音响,而换向阀易磨损,配件更换成本高。
