A backflow lifting device comprises a frame and a lifting device body arranged in the frame; a backflow drawer is fixedly arranged at the lifting end of the lifting device body and comprises a seat body and a movable drawer; the movable drawer can tilt forwards or backwards in the seat body; by applying an external force to the rear half part of the movable drawer, the movable drawer can be in a backwards-tilting state in the lifting process and during supporting a backflow workpiece, so as to support and convey workpieces; and a limiting device which interferes with the rear half part of thebottom surface of the movable drawer or the front half part of the upper edge of the movable drawer is arranged on the moving track of the movable drawer, so that the movable drawer is changed from abackward tilting state to a forward tilting state and is used for conveying the workpieces. According to the backflow lifting device, the movable drawer is controlled by the spring or self-gravity tobe kept in a backward tilting state and is used for supporting the workpieces on a conveying line; under the cooperation of a limiting device in the frame, the movable drawer is limited to keep the movable drawer in a forward tilting state, and the movable drawer is used for conveying the workpieces to the conveying line; and the backflow lifting device has the advantages that the structure is simple, manual participation is not needed in the backflow conveying process, and the device is suitable for being popularized.

    一种回流升降装置,包括机架和设于机架中的升降装置,升降装置的升降端固设有回流屉,回流屉包括座体和活动屉,活动屉可于座体中进行前倾或后仰动作,在活动屉后半部施加外力使其在升降途中和托接回流工件时均处于后仰状态,用于托接以及运送工件;在活动屉运行轨迹上设置对活动屉底面后半部或在活动屉运行轨迹上设置对活动屉上边沿前半部形成干涉的限位装置,使活动屉由后仰状态转变为前倾状态,用于输送工件。本申请通过弹簧或自身重力控制活动屉保持后仰状态,用于托接输送线上的工件;配合机架中的限位装置对活动屉形成限位使其保持前倾状态,用于将工件输送至输送线;其结构简单,回流输送过程中无需人工参与,适合推广。
