具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例提供一种可活动式流道连接机构。本发明的可活动式流道连接机构通过第二放置座的表面设置为球形曲面，连接头的首侧适配第二放置座，连接头的首侧能够在多个方向顶触第二放置座，无论连接头在任意方向顶触第二放置座时，连接头与第二放置座连接处都不会产生缝隙，使用期间，连接管的管道的轴线与第二连接件的第二开孔的轴线存在微量的偏移，但并不会影响塑料从塑料挤出机流向塑料制品生产设备中，能够在前端设备的出料口与后端设备的入料口不完全对准的情况下，将前端设备的出料口与后端设备的入料口进行无缝隙接驳(连接)。
现有的解决方案，调整塑料挤出机以及生产设备本身内部各个连接处存在的公差，通过重复调整，从而达到接驳后不存在泄漏的情况。现有的解决方案的工程量大，并且调整过程中受随机性的影响较大，可能存在长时间都在调整的情况。
如图1-4所示，本发明提供一种可活动式流道连接机构，包括连接管1、第一连接件2和第二连接件3，连接管1设置有管道11，连接管1的首端设置有连接头12，第一连接件2设置有第一放置座21，第一放置座21的底面设置有第一开孔22，连接管1的尾端穿设过第一开孔22，连接头12的尾侧与第一放置座21的表面相触， 第二连接件3设置有第二放置座31，第二放置座31的表面为球形曲面，连接头12的首侧为与第二放置座31的表面适配的球形曲面，连接头12的首侧与第二放置座31的表面相触，第二放置座31的底面设置有第二开孔32，管道11与第二开孔32连通，第一连接件2和第二连接件3之间可拆卸地固定连接。
本方案的可活动式流道连接机构原理如下：
在第一连接件2和第二连接件3固定连接后，第一连接件2的第一放置座21顶触连接头12的尾侧，使连接头12的首侧顶触第二连接件3的第二放置座31，并由于第二放置座31的表面为球形曲面，同时连接头12的首侧为与第二放置座31的表面适配的球形曲面，连接头12的首侧能够在多个方向顶触第二放置座31，并且无论连接头12在任意方向顶触第二放置座31时，连接头12与第二放置座31连接处都不会产生缝隙。
如图5所示，使用期间，连接管1的尾端连接前端的塑料挤出机的出料口，第二连接件3连接后端的塑料制品生产设备的进料口(连接管的“首端”、“尾端”分别对应的是连接管的沿物流方向的起始端、末端；连接头的“首侧”、“尾侧”分别对应的是连接头的沿物流方向的起始侧、末侧)。虽然，由于塑料挤出机以及生产设备本身内部各个连接处存在一定的公差，前端的塑料挤出机的出料口与后端的塑料制品生产设备的进料口无法完全对准，实际情况与设备图纸理想的结构存在一定的偏差，塑料挤出机和塑料制品生产设备之间接驳流道连接机构，塑料挤出机以及生产设备本身存在的公差的影响会作用于流道连接机构中，但是，该偏差毕竟为公差 产生的系统性偏差，偏移量有限，受到影响，连接管1的管道11的轴线与第二连接件3的第二开孔32的轴线存在微量的偏移，但并不会影响熔解的塑料从塑料挤出机的出料口挤出经过管道11和第二开孔32顺利流向塑料制品生产设备中。
本方案的可活动式流道连接机构能够在前端设备的出料口与后端设备的入料口不完全对准的情况下，将前端设备的出料口与后端设备的入料口进行无缝隙接驳。
一种实施例，第一连接件2和第二连接件3之间具有间隔4。
本实施例中，在理论上，塑料挤出机的出料口与塑料制品生产设备的进料口的偏差会作用于第一连接件2和第二连接件3，第一连接件2和第二连接件3之间会存在与塑料挤出机的出料口与塑料制品生产设备的进料口之间的相同夹角，而间隔4的目的在于提供第一连接件2和第二连接件3偏移的空间，
一种实施例，连接头12的中段的外径小于第二放置座31的顶部的口径，第二放置座31的顶部不与连接头12相触。
本实施例中，由于连接管1的管道11的轴线与第二连接件3的第二开孔32的轴线存在微量的偏移，而在实际情况下，偏移方向是不能确定的，可以看作，在最终固定前，连接头12会随机在不同方向转动，该结构中，第二放置座31覆盖连接头12的首端，提供连接头12的首端的转动空间，但连接头12的首端不完全和第二放置座31接触，又使得连接头12的首端转动时不会超出第二放置座31外与其它零件接触。
一种实施例，第一放置座21的表面为圆台面或球形曲面，连接头12的尾侧为 与第一放置座21的表面适配的圆台面或球形曲面。
本实施例中，将第一放置座21的表面设置为圆台面或球形曲面，能够使第一放置座21的表面与连接头12的尾侧之间的总接触面积和轴向方向的接触面积都更充足，第一放置座21充分顶触连接头12压向第二放置座31，保证连接头12的首端与第二放置座31的表面之间的密封性，并且不会影响连接管1的尾端连接前端的塑料挤出机的出料口。
一种实施例，第一连接件2和第二连接件3之间通过设置螺栓5连接。
本实施例中，在第一连接件2和第二连接件3沿轴线的周围设置通孔23或螺孔33，通孔23和螺孔33的位置对应，通过螺栓5将第一连接件2和第二连接件3固定连接。
具体的，第一连接件2设置有通孔23，第二连接件3设置有33螺孔，通孔23和螺孔33的位置对应，螺栓5穿设过通孔23后与螺孔33螺接。将螺栓5的头部设置在第一连接件2的一侧，螺栓5的螺纹部设置在第二连接件3的一侧，在安装螺栓5将第一连接件2和第二连接件3固定时，有效地使第一连接件2压向连接头12，并将连接头12压向第二放置座31。
再具体的，螺栓5和第一连接件2之间设置有橡胶垫片51。由于螺栓5与第二连接件3螺接，再由于第一连接件2和第二连接件3之间会存在一定夹角，会导致螺栓5的头部不能与第一连接件2完全接触，通过借助橡胶垫片51的可变形特性，抵消第一连接件2和第二连接件3之间存在夹角带来的影响，
具体的，第一连接件2的外侧面和第二连接件3的外侧面设置有固定套6，通过固定套6将第一连接件2和第二连接件3进一步加固。
一种实施例，连接管1的尾端和第一开孔22之间为间隙配合。
一种实施例，连接管1和第一连接件2通过一体连接。
一种实施例，连接管1和第一连接件2通过一体成型。
对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发明。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
