S2：推袋组件动作：复位状态下推袋气缸处于伸出位置，推袋升降气缸处于回收位置，包装袋到位后推袋升降气缸伸出带动推袋板下行到推袋位置，后推袋气缸回缩将推袋升降气缸、推袋板均朝后滑移，即将包装袋从挂袋杆上推送至送袋输送带上；
S3：送袋机构及撑袋机构动作：包装袋经送袋输送带输送至端部后经张袋气缸驱动张袋吸盘吸附包装袋口将其张开，袋口张开后水平套袋气缸回缩使纵向撑袋板插入袋中，接着水平撑袋气缸伸出，通过送袋同步带使左右两个纵向撑袋板往两侧移动撑开包装袋，张袋气缸复位，再由水平移动气缸将撑开的包装袋移动到预套袋位置，即撑袋组件位置，将袋口套到撑袋板上；

S7：当物料即将走出进料对中组件时，对射传感器做一次检测，撑袋组件已携带包装袋就位，推包臂直接前进，物料途经两撑袋模具进入包装袋；物料完全落于包装袋中而继续前进时，两撑袋模具不再夹紧包装袋，包装袋和物料一齐被 推包臂向前推包至热封工位，两对中夹板夹住物料包(带物料包装袋)时，摆正物料包的同时靠摩擦力使物料包带有阻尼，推包臂的移动速度降低；当物料与包装袋缓慢向前移动时，包装袋的袋口逐渐脱离撑袋模具，当撑袋模具的圆孔露出时，上下对射竖直光路通，包装袋的袋口位置被对射感应器检测，推包电机开始计算脉冲；

本发明还提供了上述真空包装二次装袋机的工作方法，按以下步骤进行：
S1：供袋机构动作：首先分度盘转动将一挂袋杆转至推袋位置后停止；
S2：推袋组件动作：复位状态下推袋气缸处于伸出位置，推袋升降气缸处于回收位置，包装袋到位后推袋升降气缸伸出带动推袋板下行到推袋位置，后推袋气缸回缩将推袋升降气缸、推袋板均朝后滑移，即将包装袋从挂袋杆上推送至送袋输送带上；
S3：送袋机构及撑袋机构动作：包装袋经送袋输送带输送至端部后经张袋气缸驱动张袋吸盘吸附包装袋口将其张开，袋口张开后水平套袋气缸回缩使纵向撑袋板插入袋中，接着水平撑袋气缸伸出，通过送袋同步带使左右两个纵向撑袋板往两侧移动撑开包装袋，张袋气缸复位，再由水平移动气缸将撑开的包装袋移动到预套袋位置，即撑袋组件位置，将袋口套到撑袋板上；
S31：送袋机构及撑袋机构复位：水平撑袋气缸复位将两纵向撑袋板相向靠近，水平套袋气缸伸出将纵向撑袋板脱出袋口，套袋升降气缸复位带动纵向撑袋板上行，水平移动气缸回缩将整体平移复位；
S4：撑袋组件动作：
S41：撑袋组件的上袋工位动作：初始状态下，上、下方撑袋气缸均处于伸出位置，待包装袋套到撑袋板上之后，上、下方撑袋气缸同时收缩动作，将包装袋口撑开；
S42：撑袋组件的推袋工位动作：撑袋组件撑着包装袋口，经第一驱动组件驱动由上袋工位平移至推袋工位后，等待推包；
S5：进料对中组件动作：物料位于第一托板并经两对中导板靠拢进行对中导正，等待推包；
S6：初始状态下，推包臂位于推包原点；待物料于进料对中组件上准备就绪，在对中导板的导向下推包臂向前推动物料；
S7：当物料即将走出进料对中组件时，对射传感器做一次检测，撑袋组件已携带包装袋就位，推包臂直接前进，物料途经两撑袋模具进入包装袋；物料完全落于包装袋中而继续前进时，两撑袋模具不再夹紧包装袋，包装袋和物料一齐被推包臂向前推包至热封工位，两对中夹板夹住物料包(带物料包装袋)时，摆正物料包的同时靠摩擦力使物料包带有阻尼，推包臂的移动速度降低；当物料与包装袋缓慢向前移动时，包装袋的袋口逐渐脱离撑袋模具，当撑袋模具的圆孔露出时，上下对射竖直光路通，包装袋的袋口位置被对射感应器检测，推包电机开始计算脉冲；
S8：袋口被检测后，撑袋组件先行撤出，物料到达终点后推包臂撤出，在物料封口时推包臂以全速回退至原点，进行下一个工作流程；紧接着：
S81：理袋热封组件的理袋动作：初始状态下，上、下热封气缸处于缩回状态，上、下预成型理袋夹处于打开状态，理袋切于物料左右准备就位；由伺服电机设定理袋切的运动规律，待热封物料就位后，理袋切上的吹气管开始吹气，理袋切对中切入打在包装袋的袋口侧面中线上，使风琴袋形成稳定的“M”边；此时，上、下预成型理袋夹动作，同时理袋切进一步切入，直到上、下预成型理袋夹动作完毕，仅余一条细缝供理袋切撤出时，袋口预成型完毕；
S82：理袋热封组件的热封动作：上述袋口预成型完毕且理袋切撤出后，上热封板先行动作，其动作终点落在理袋夹的中线上，其后下热封板动作，将袋口夹紧并停留一定时间以完成热封；
S9：出料机构：热封完成后经出料机构的出料输送带出料。
在本发明实施例中，为了实现真空包装二次装袋机的自动控制，所述真空包装二次装袋机还包括PLC控制器；所述PLC控制器与对射传感器电性连接，以通过对射传感器在不同阶段检测撑袋机构是否已携包装袋位于套袋工位，以及检测包装袋的袋口位置；所述PLC控制器与撑袋机构的控制端电性连接，以控制撑袋机构在套上包装袋后撑开包装袋，并携带包装袋运动至套袋工位，以及控制撑袋机构在对射传感器检测到包装袋的袋口位置后退回起始工位；所述PLC控制器与进料对中组件的控制端电性连接，以控制进料对中组件对放置其上的物料进行对中导正；所述PLC控制器与推包机构的控制端电性连接，以控制推包机构的推包臂推动进料对中组件上的物料进入包装袋，并带动包装袋一起运动至理袋热封工位，以及控制推包臂在套有包装袋的物料，即物料包到达理袋热封工位后快速退回起始工位；所述PLC控制器与理袋热封组件的控制端电性连接，以控制理袋热封组件对物料包进行理袋热封，从而得到二次装袋的真空包装产品。
在本发明实施例中，所述对射传感器采用高精度激光检测传感器，当撑袋机构已携包装袋就位时，包装袋挡住对射传感器的对射光路，从而根据对射光路是否被遮挡判断撑袋机构是否已携包装袋位于套袋工位；当包装袋随物料一起向前运动至对射传感器的对射光路导通时，对射光路导通瞬间即为包装袋的袋口离开瞬间，从而得到包装袋的袋口位置；所述PLC控制器检测到包装袋的袋口位置后，计算推包臂还需要运动的距离，通过对驱动推包臂的推包伺服电机进行脉冲控制，驱动推包臂运动设定距离，从而实现对封口位置的精确定位。
本推包机构中封口高度与理袋高度受结构约束始终一致，且由图10中的封口高度调节电机控制，而理袋切受水平理袋伺服电机控制，所有动力皆为电控，切换包装规格时只需选择预设的参数组合，即可快速且精准地调整好机构，无需 手动干涉，安全、高效、便捷。
以上所述，仅是本发明的较佳实施例而已，并非是对本发明作其它形式的限制，任何熟悉本专业的技术人员可能利用上述揭示的技术内容加以变更或改型为等同变化的等效实施例。但是凡是未脱离本发明技术方案内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与改型，仍属于本发明技术方案的保护范围。

    S5：进料对中组件动作：物料位于第一托板并经两对中导板靠拢进行对中导正，等待推包；
    S6：初始状态下，推包臂位于推包原点；待物料于进料对中组件上准备就绪，在对中导板的导向下推包臂向前推动物料；
    S7：当物料即将走出进料对中组件时，对射传感器做一次检测，撑袋组件已携带包装袋就位，推包臂直接前进，物料途经两撑袋模具进入包装袋；物料完全落于包装袋中而继续前进时，两撑袋模具不再夹紧包装袋，包装袋和物料一齐被推包臂向前推包至热封工位，两对中夹板夹住物料包(带物料包装袋)时，摆正物料包的同时靠摩擦力使物料包带有阻尼，推包臂的移动速度降低；当物料与包装袋缓慢向前移动时，包装袋的袋口逐渐脱离撑袋模具，当撑袋模具的圆孔露出时，上下对射竖直光路通，包装袋的袋口位置被对射感应器检测，推包电机开始计算脉冲；
    S8：袋口被检测后，撑袋组件先行撤出，物料到达终点后推包臂撤出，在物料封口时推包臂以全速回退至原点，进行下一个工作流程；紧接着：
    S81：理袋热封组件的理袋动作：初始状态下，上、下热封气缸处于缩回状态，上、下预成型理袋夹处于打开状态，理袋切于物料左右准备就位；由伺服电 机设定理袋切的运动规律，待热封物料就位后，理袋切上的吹气管开始吹气，理袋切对中切入打在包装袋的袋口侧面中线上，使风琴袋形成稳定的“M”边；此时，上、下预成型理袋夹动作，同时理袋切进一步切入，直到上、下预成型理袋夹动作完毕，仅余一条细缝供理袋切撤出时，袋口预成型完毕；
    S82：理袋热封组件的热封动作：上述袋口预成型完毕且理袋切撤出后，上热封板先行动作，其动作终点落在理袋夹的中线上，其后下热封板动作，将袋口夹紧并停留一定时间以完成热封；
    S9：出料机构：热封完成后经出料机构的出料输送带出料。
  11. 根据权利要求10所述的一种真空包装二次装袋机的工作方法，其特征在于：所述真空包装二次装袋机还包括PLC控制器；所述PLC控制器与对射传感器电性连接，以通过对射传感器在不同阶段检测撑袋机构是否已携包装袋位于套袋工位，以及检测包装袋的袋口位置；所述PLC控制器与撑袋机构的控制端电性连接，以控制撑袋机构在套上包装袋后撑开包装袋，并携带包装袋运动至套袋工位，以及控制撑袋机构在对射传感器检测到包装袋的袋口位置后退回起始工位；所述PLC控制器与进料对中组件的控制端电性连接，以控制进料对中组件对放置其上的物料进行对中导正；所述PLC控制器与推包机构的控制端电性连接，以控制推包机构的推包臂推动进料对中组件上的物料进入包装袋，并带动包装袋一起运动至理袋热封工位，以及控制推包臂在套有包装袋的物料，即物料包到达理袋热封工位后快速退回起始工位；所述PLC控制器与理袋热封组件的控制端电性连接，以控制理袋热封组件对物料包进行理袋热封，从而得到二次装袋的真空包装产品。
  12. 根据权利要求11所述的一种真空包装二次装袋机的工作方法，其特征在于：所述对射传感器采用高精度激光检测传感器，当撑袋机构已携包装袋就位时，包装袋挡住对射传感器的对射光路，从而根据对射光路是否被遮挡判断撑袋机构是否已携包装袋位于套袋工位；当包装袋随物料一起向前运动至对射传感器的对射光路导通时，对射光路导通瞬间即为包装袋的袋口离开瞬间，从而得到包 装袋的袋口位置；所述PLC控制器检测到包装袋的袋口位置后，计算推包臂还需要运动的距离，通过对驱动推包臂的推包伺服电机进行脉冲控制，驱动推包臂运动设定距离，从而实现对封口位置的精确定位。
