Description

底模双边锁定机构
技术领域
本发明涉及饮料瓶加工设备领域，特别涉及吹瓶机的底模双边定位机构。
背景技术
现有技术中的吹瓶机一般包括机架、设置在机架上的左右模和底模、以及驱动机构和定位机构，如公告号为CN201755911U中公开的一种直线式吹瓶机的底模锁定装置，包括模具安装板、瓶模模腔、底模、动力机构、定位机构与支座，瓶模模腔尾段套接底模，底模连接动力机构，定位机构水平设置在支座上，定位机构包括定位卡块气缸与定位卡块，定位卡块与定位卡块气缸连接，动力机构包括底模安装板与底模升降气缸，底模安装板上表面连接底模，下表面连接底模升降气缸，底模升降气缸固定在支架上。可见，该专利中的底模锁定装置需要2个动力机构分别驱动两侧的定位机构，使得能源损耗较大，且设备体积庞大。
发明内容
本发明所要解决的技术问题是提供一种改进的底模双边锁定机构。
为解决以上技术问题，本发明采用如下技术方案：一种底模双边锁定机构，该锁定机构安装在吹瓶机上，锁定机构包括能够绕一第一轴线转动的转轴、用于驱动转轴转动的动力源、可滑动地设置于吹瓶机的机架上的多个滑块、可摆动地设置于机架上并在摆动时牵引滑块移动的多个摆动件、用于控制多个摆动件摆动的固定设置在转轴上的转动件。在锁定机构处于锁定状态时，多个滑块插入底模与机架之间且抵住底模，在锁定机构处于解锁状态时，滑块离开底模。动力源驱动转轴，转轴带着转动件转动，转动件在转动时引起多个摆动件的摆动，从而通过多个摆动件牵引多个滑块移动，以对底模进行多处支撑定位或释放。
模进一步地，多个滑块包括第一滑块和第二滑块，机架上设置有第一导轨和第二导轨，第一滑块和第二滑块分别沿着第一导轨和第二导轨滑动地设置，多个摆动件包括第一摆动件和第二摆动件，第一摆动件、第二摆动件分别相应地牵引第一滑块、第二滑块滑动。通过两个摆动件的摆动来分开控制两个滑块的滑动，更利于控制方式的简单化设计。
更进一步地，转动件的外缘面上具有第一导向面和第二导向面，第一摆动件上形成朝向转动件突出的第一凸块，第二摆动件上形成朝向转动件突出的第二凸块，在转动件相对机架转动时，第一导向面与第一凸块相对滑动地接触，第二导向面与第二凸块相对滑动地接触，且第一导向面与第一凸块接触的位置以及第二导向面与第二凸块接触的位置与转动件的转动轴线之间的距离随转动件的转动而变化，通过这种距离变化，产生对凸块的导向作用，使得凸块位置移动，两个摆动件便可产生相应的摆动。
更进一步地，第一滑块和第二滑块上分别形成有第一凸起和第二凸起，第一摆动件在离其与机架连接的位置一段距离处开设一第一滑槽，第二摆动件在离其与机架连接的位置一段距离处开设一第二滑槽，第一凸起可滑动地插在第一滑槽中，第二凸起可滑动地插在第二滑槽中。两个摆动件的开滑槽的位置形成拨叉构造，摆动件通过该拨叉控制滑块的滑动。
更进一步地，第一滑块和第二滑块分列于底模的相对两侧，通过位于底模相对两侧的两个滑块来实现对底模的双边定位，以使定位更加可靠。
在一具体的实施例中，在各摆动件与机架之间设置一弹性部件，用于提供复位力给摆动件。例如，在转动件转动的过程中，当凸块和导向面接触的位置离第一轴线越来越远时，摆动件即被转动件推着发生摆动；反之，若在转动件转动的过程中，凸块和导向面接触的位置离第二轴线越来越近，摆动件即需要外力来牵引着才能产生摆动，而此处的弹性部件即用来提供所需要的这种外力。当然，也可以通过其它方式来提供该外力，例如通过转动件牵拉摆动件的方式。
优选地，底模、多个摆动件、多个滑块以及转动件等位于机架的上表面的上侧。
本发明的有益效果在于:只采用一个动力源即可实现多个滑块对底模的同时定位，既能使定位可靠，又可节省能源，减小设备体积。
附图说明
附图1为根据本发明实施的底模锁定机构在解锁状态下的俯视图（开模状态）；
附图2为根据本发明实施的底模锁定机构在锁定状态下的俯视图（合模状态）；
其中：2、机架；5、转轴；7、转动件；11、底模；31、第一滑块；32、第二滑块；33、第一导轨；34、第二导轨；35、第一摆动件；351、第一扭簧；36、第二摆动件；361、第二扭簧；37、第一凸块；38、第二凸块；41、第一凸起；42、第一滑槽；51、第二凸起；52、第二滑槽；71、第一导向面；72、第二导向面。
具体实施方式
下面结合附图对本发明作进一步阐述。
图1-2反映了根据本发明的底模双边锁定机构，该锁定机构应安装在吹瓶机上，由于吹瓶机的其它部件并不是本发明的要点，且已为本领域技术人员所熟知，因此，未在图中显示出来。
各图中所示的锁定机构包括相对机架2能够绕自身轴心线转动的转轴5、固定设置在转轴5上的转动件7、与转动件7配合的多个摆动件、可相对机架2滑动地设置的多个滑块，各个摆动件分别枢轴转动连接于机架2。转动件7在转轴5的带动下转动，在转动件7转动时驱使多个摆动件相对机架2摆动，从而控制多个滑块滑动。转轴5由动力源驱动而驱动而转动，动力源为本领域常见设备，因此未在附图中显示出来。
已知的是，吹瓶机上具有吹模组件，包括左右模及图1-2中可见的底模11。当吹模组件处于合模状态时，左右模相结合，底模11也朝左右模靠拢，三者之间形成一型腔，此时，底模11需要被定位，根据本发明的锁定机构即用来对底模11进行定位。在合模状态时，锁定机构处于锁定状态，多个滑块插入底模11与机架2之间且抵住底模11。
具体地，滑块包括第一滑块31和第二滑块32，摆动件包括第一摆动件35和第二摆动件36，第一滑块31和第一摆动件35构成第一定位单元，第二滑块32和第二摆动件36构成第二定位单元。第一定位单元和第二定位单元分别还包括大致沿水平方向延伸地设置在机架2上的第一导轨33和第二导轨34，第一滑块31和第二滑块32分别沿着第一导轨33和第二导轨34滑动地设置。在图1-2所示的实施例中，第一导轨33和第二导轨34均为直线形导轨。
转动件7上设置有第一导向面71和第二导向面72，第一摆动件35和第二摆动件36上分别设置有第一凸块37和第二凸块38，在转动件7随转轴5转动时，第一凸块37沿着第一导向面71滑动，第二凸块38沿着第二导向面38滑动。
第一导向面71可以如同图1-2所示的那样为渐开线形的构造，其沿转轴5的半径所在直线的纵截面外缘与转轴5的轴心线之间的距离按顺时针方向越来越大或越来越小，当然第一导向面71也可以为其它曲面构造，如同图1-2所示的第二导向面72。图1-2中所示的第二导向面72为异形曲面构造，其具有“峰”和“谷”，或者，第二导向面72也可以参照第一导向面71的设计。第一导向面71和第二导向面72的形成，主要是为了使两个凸块分别和两个导向面接触的位置与转轴5的轴心线之间的距离随着转动件7的转动而变化，从而产生两个摆动件的摆动。
优选地，在第一摆动件35与机架2之间设置第一扭簧351，在第二摆动件36与机架2之间设置有第二扭簧361，分别用于提供复位力给第一摆动件35和第二摆动件36。参照图1-2的变化，转动件7按照逆时针方向转动，由于第一导向面71和第二导向面72（由“峰”到 “谷”）的导向作用，与之相接触的第一凸块37和第二凸块38便可以朝靠近转轴5的轴心线（即转轴5相对机架2转动的转动轴线）的方向移动，此时，第一摆动件35在第一扭簧351的作用力下逆时针转动，第二摆动件36在第二扭簧361的作用力下顺时针摆动，两个摆动件的拨叉部分分别带动两个滑块沿导轨移动至图3所示的位置，即：两个滑块插入底模11与机架2之间并抵住底模11，对底模11形成定位。再参照图2-图1的变化，转动件7按顺时针方向转动，由于第一导向面71与第一凸块37接触的位置离转轴5的轴心线越来越远，第二导向面72与第二凸块38接触的位置也由“谷”变到“峰”，因而两个凸块被推着发生位移，在此过程中，第一摆动件35克服第一扭簧351的作用力按顺时针方向转动，第二摆动件36克服第二扭簧361的作用力按逆时针方向转动，并通过各自的拨叉部分带动两个滑块移动至图2所示的位置，即：两个滑块脱离底模11，从而将底模11释放。
第一滑块31和第二滑块32的上表面分别形成有第一凸起41和第二凸起51，第一摆动件35和第二摆动件36的离各自相对机架2转动的轴线一段距离处分别形成有第一滑槽42和第二滑槽52，第一凸起41可滑动地插在第一滑槽42中，第二凸起51可滑动地插在第二滑槽52中。两个摆动件上开设滑槽的部分形成拨叉结构，用于拨动两个滑块在导轨上来回滑动。。
第一滑块31和第二滑块32设置在底模11的相对两侧，便可以对底模11的两侧边进行定位，使得定位更可靠。
第一定位单元和第二定位单元位于机架2的上表面之上，转动件7和底模11等部件也处于机架2的上表面的上侧。
当吹模组件处于合模状态时，底模11相对机架2上升而与机架2之间形成一段间隔，滑块插入底模11与机架2之间且抵住底模11；当吹模组件开模时，动力源带动转轴5转动，转轴5带动转动件7转动，当转动件7转动时，第一凸块37沿着第一导向面71滑动，第二凸块38沿着第二导向面38滑动，使得第一摆动件35和第二摆动件36发生相对机架2的摆动，从而带动第一滑块31和第二滑块32分别沿着第一导轨33和第二导轨34滑动，继而锁定机构解锁，底模11可朝机架2回落。
上述实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范围。凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围之内。
