图1所示为一种包装盒101，包装盒101端部具有两个相对的侧盖1011，以及位于侧盖1011之间的两个主盖1012，包装盒的侧盖1011与两个相对的侧面板1013连接，包装盒的主盖1012与两个相对的主面板1014连接，包装盒撑开后的盒口1015大致呈矩形。侧盖1011的具体结构根据不同的包装需要有 所不同，图1中所示，侧盖1011上设置扣舌1016。对此包装盒进行封盒时，需将包装盒撑开，待放入被包装物料后，再将侧盖1011弯折，并使扣舌1016相互勾挂，再对主盖1012进行封合。
参考图2和图3，本申请第一种实施方式提出一种封盒装置1，包括折盖组件，所述折盖组件包括两个相对设置的转动杆11；
所述转动杆11一端凸设有弯折件12，两个所述弯折件12相向弯折设置，所述弯折件12与所述转动杆11呈锐角设置。
本实施方式提供的封盒装置1，两个转动杆11带动侧盖1011转动至预设位置时，两个弯折件12将两个侧盖1011弯折并使他们形成一定角度的钝角，使得侧盖的扣舌1016一定程度上相互勾挂，再进行前盖1012或后盖1013的按压，两个侧盖1011会完全勾住，封盒装置1结构简单且稳定性高。
具体地，所述弯折件12包括贴设于所述转动杆11上的固定部121，以及凸设于所述固定部121上的弯折部122。弯折件12与转动杆11之间的呈锐角设置，因此弯折部122与转动杆11之间成锐角，固定部121和弯折部122形成一定角度的锐角。作为优选，所述固定部121与所述转动杆11之间可拆卸链接。可以加工多种规格尺寸的弯折件12，在使用时，可以根据包装盒的尺寸或者型号更换弯折件12以适应不同型号的包装盒。
作为一种优选，所述弯折部122与所述固定部121之间的角度在60-85度之间。弯折部122与固定部121之间的角度可根据侧盖的形状或尺寸进行调整，以具有图1所示扣舌侧盖的包装盒为例，两个侧盖在形成160度左右的钝角时，两个侧盖的扣舌勾挂会很稳定，在下一步的前盖和后盖扣合时，两个侧盖实现完全勾挂。
作为一种优选实施方式，如图4和图5所示，所述弯折件12包括与所述转动杆11连接的弯折件本体123，所述弯折部122设于所述弯折件本体123远离所述转动杆11一端，两个所述弯折部122相互交错设置，两个所述弯折部122不会在运动过程中相互干涉，从而可以将侧盖1011弯折到预设的位置。具体地，所述弯折件本体123通过固定部121与所述转动杆11连接，也就是说所述弯折件本体123连接所述固定部121与弯折部122。此处弯折部122设于弯折件本体123的一端，在两个转动杆11相向移动时，两个弯折部122将侧盖1011弯折，并且由于相互交错设置，两个弯折部122不会相互碰撞，从而可以将侧盖1011尽量弯折。弯折件本体123与转动杆11基本成直角，侧盖1011被弯折后，弯折件本体123基本与侧盖1011贴合，可以防止侧盖1011变形。弯折部122与固定部121之间成锐角，因此，弯折部122与弯折件本体123之间成钝角，两个转动杆11移动到预设位置之后，两个弯折部122之间形成一个夹角，使得两个侧盖1011也呈一定夹角设置，使得两个侧盖1011在一定程度上相互勾挂。
两个转动杆11在弯折侧盖过程中可以通过转动相互靠近或相互远离，具体地，如图4所示，所述封盒装置1还包括安装架111，所述转动杆11铰接在所述安装架111两侧，所述转动杆11与第一驱动件112连接以驱动两个所述转动杆11相向移动。所述第一驱动件112一端与所述转动杆11连接以驱动转动杆11相互靠近或远离，所述第一驱动件112与所述转动杆11远离弯折件12的一端可转动地连接，所述驱动件112另一端与安装架111连接。转动杆11的长度可根据需要设置。此处需要说明的是，转动杆11可选用材质或者中空等方式以降低重量。第一驱动件112选取爪型气缸，重量低，成本低且寿命长，也可为其他的驱动形式，如电缸或液压缸等，可根据需要选择。
可选地，两个所述转动杆11对称设置，且两个所述转动杆11联动，以适用于两个侧盖相同的包装盒，保证两个侧盖的同步弯折和勾挂。
作为一种优选实施方式，如图5所示，所述转动杆11上还设有第一凸起件113，两个所述第一凸起件113相对设置，以限制两个所述转动杆11之间的最小距离，从而可以防止两个转动杆11的间距过小，转动杆11与侧盖1011的接触位置过于靠近侧盖1011的边缘，因而无法有效的对两个侧盖1011施加压力，实现侧盖1011的插入。此处第一凸起件113为设于转动杆11上的螺栓，可通过调节螺栓凸出于转动件11的高度，来调节两个转动杆11之间的最小间距，从而适应不同尺寸侧盖1011弯折和插入的需要。第一凸起件113数量可设置为两个，即，两个转动杆11上各设置一个，两个第一凸起件113相对设置。具体地，转动杆11包括：与安装架111可转动地连接的转动部1101，以及与转动部1101连接的杆部1102。杆部1102与转动部1101可拆卸连接，第一凸起件113设置在转动部1101上。因此，在弯折不同规格的侧盖时，无需拆卸整个转动杆，只需更换杆部即可。第一凸起件113位于转动部1101上，第一凸起件113向两个转动杆11之间凸起。
为了进一步提高勾挂的成功率，作为一种优选实施方式，如图4和图5所示，两个所述转动杆11上分别设有第二凸起件114，所述第二凸起件114设于其中一个转动杆11上并向另一转动杆11凸起，所述第二凸起件114的凸起高度小于所述弯折件12的凸起高度，即，所述第二凸起件114与转动杆11远离第一驱动件112的端部相连接，并且向两个转动杆11之间凸起。通过第二凸起件114和弯折件12的配合，在两个转动杆11相向移动时，弯折件12将侧盖1011弯折到预设位置时，第二凸起件114将会与盒体接触，并且压迫盒体使其 变形，稍稍变形的盒体其侧盖的勾挂更为简单，本实施方式的封盒装置用于侧盖的弯折及勾挂，结构简单且成功率高。
作为优选，如图5所示，所述转动杆11上设有第一导轨115，所述弯折件12可沿所述第一导轨115移动，以靠近或远离所述第二凸起件114。因不同侧盖1011的其受力的最佳位置与盒体的受力位置之间的距离不同，因此，可以通过调整弯折件12和第二凸起件114之间的距离，来满足不同尺寸或者形状的包装盒的弯折侧盖的需要。作为优选，所述第一导轨115为设于所述转动杆11上的滑槽，所述弯折件12卡设于所述滑槽中，从而沿所述滑槽移动，当移动至预设位置时，可通过螺栓或者卡扣等方式将所述弯折件12与所述转动杆11相互固定。此处需要说明的是，第一导轨115并不限于上述结构，导轨也可采用凸设于转动杆11上的滑杆或滑道等结构，再与螺栓或卡扣等配合进行定位。例如，弯折件12通过可滑动的卡扣与转动杆11连接，可实现弯折件12和第二凸起件114之间的距离的有效调节即可。
为了提高勾挂成功率，如图6所示，作为一种优选实施方式，所述封盒装置1还包括设于两个转动杆11之间的扣合机构13，扣合机构13包括第二驱动件131和旋转片132，第二驱动件131可拆卸的连接在安装架111上，旋转片132固定在第二驱动件131上随第二驱动件131旋转，两个所述转动杆11位于旋转片132的两侧。本实施方式中第二驱动件131选取旋转气缸。封盒装置1通过设置扣合机构13，在侧盖1011弯折的同时，旋转片132插入两侧盖1011之间，第二驱动件131带动旋转片132旋转180°，实现侧盖1011的勾挂使侧盖1011的扣舌1016完全扣合，该装置结构简单并且侧盖1011完全扣合的成功率高。
作为优选，如图7所示，所述弯折件12还包括延长部124，所述弯折件本体123一端与所述转动杆11连接，所述弯折件本体123另一端与所述延长部124连接，两个所述弯折件12的延长部124交错设置。弯折件本体123一端通过固定部121与所述转动杆11连接，弯折件本体123另一端通过弯折部122与所述延长部124连接，即，延长部124设于弯折部122的端部，延长部124作为弯折部122的延伸相互交错设置。所述延长部124相对于所述弯折件本体123向靠近所述旋转片132的方向倾斜，使两个转动杆11到达预设位置之后两个延长部124之间能形成一定的夹角，与延长部124接触的侧盖1011之间也能形成一定的夹角，便于后续侧盖1011扣合。两个延长部124交错设置，使两个延长部124在运行过程中不会互相干扰，可以将侧盖1011弯折到预设位置。本实施方式中，转动杆11上也可设置第一导轨115，使得弯折件12可以沿着第一导轨115移动，从而靠近或远离安装架111，并且弯折件12可定位在转动杆11上预设位置，以适应不同规格的侧盖1011弯折和勾挂。本实施方式中，第一导轨115选取滑槽，弯折件12上设置有与滑槽配合的滑块，当移动至预设位置时，可以通过螺栓等方式固定住。
如图8和图9所示，作为上述实施方式的一种优选，弯折件本体123的端部设有扣合片125，所述扣合片125位于所述延长部124的一侧，一个转动杆11上的延长部124和扣合片125与另一个转动杆11上的延长部124和扣合片125交错设置。扣合片125和延长部124均设于弯折件本体123的端部，两者并排设置，由于延长部124交错设置，因此扣合片125也相互交错，使得弯折件12在相向运动时不会互相干扰。也就是说，其中一个转动杆11上的延长部124与另一个转动杆11上的扣合片125相对设置。第一驱动件112驱动两个转 动杆11相向移动，同时带动弯折件12相互靠近，弯折件12进而与盒体接触，在延长部124弯折侧盖1011时，扣合片125下压一侧的侧盖1011，同时扣合片125插入另一侧的侧盖1011边沿，进一步提高了两个侧盖1011勾挂的成功率，实现侧盖1011的扣合。
本申请第一种实施方式提供的封盒装置1作为包装机的一部分应用于物料包装时，通常需要安装到包装机上，因此，如图2、图4、图6和图8所示，封盒装置1还包括：与所述安装架111连接的安装框架116，与安装框架116连接的第三驱动件118，第三驱动件118安装在机架117上，第三驱动件118可驱动所述安装框架运动。为了稳定封盒装置1的运动，可在所述机架117上设置第二导轨119，所述转动杆11可在所述第三驱动件118的驱动下沿所述第二导轨119移动。第三驱动件118选取电缸，调节更加精确。第三驱动件118可驱动转动杆11靠近包装盒101移动。具体地，第三驱动件118可选取电缸，也可采用其他能驱动折盖组件分段定位移动的驱动件。第三驱动件118驱动转动杆11向包装盒101分段移动，使得该封盒装置1可以分多段将侧盖1011弯折，以适应不同尺寸的包装盒101弯折和勾挂侧盖1011的需要。
本申请第一种实施方式提供的封盒装置结构简单，安装方便，用于产品包装时，可与盒胚展开、包装盒抓取、抓料等作业流程所使用的装置组合使用，也可以与主盖或侧盖的其他封装流程所使用的组件组合使用。
本申请第二种实施方式还提出一种包装机，包括前文所述的封盒装置1。
本申请第三种实施方式还提出一种侧盖勾挂的方法，包括如下步骤：
第一驱动件112驱动两个转动杆11相向运动，带动固定在转动杆11上的弯折件12相向运动；
两个弯折件12的弯折部15相互靠近，接触到包装盒并使包装盒侧盖1011弯折；
扣合机构13的旋转片132插入弯折的侧盖1011之间；
第二驱动件131带动旋转片132旋转一次，旋转角度为180°，侧盖1011的完全扣合；
第三驱动件118带动封盒装置1远离包装盒101。
上述方法实现了具有扣舌的侧盖的勾挂扣合，结构简单，侧盖1011勾挂成功率高。
作为一种优选实施方式，所述方法还包括如下步骤：
第三驱动件118带动封盒装置1到达指定位置；
第一驱动件112驱动两个转动杆11相向运动，带动固定在转动杆11上的弯折件12相向运动；
两个弯折件12的弯折部15相互靠近，接触到包装盒并使包装盒侧盖1011弯折；
扣合片125下压一侧的侧盖1011，并插入另一侧的侧盖1011边沿，使得侧盖1011初步勾挂；
扣合机构13的旋转片132插入弯折的侧盖1011之间；
第二驱动件131带动旋转片132旋转一次，旋转角度为180°，侧盖1011的完全扣合；
第三驱动件118带动封盒装置1脱离包装盒。
上述方法，扣合片和旋转片分步作用在侧盖上，实现侧盖的两次勾挂，大大提高了侧盖勾挂的成功率。
