Box body assembly, vertical box filling machine and fruit and vegetable sorting equipment Technical Field The embodiment of the application relates to the technical field of fruit and vegetable sorting, in particular to a box assembly, a vertical box filling machine and fruit and vegetable sorting equipment. Background In vertical boxing machines, some box assemblies employ flexible doors to open and close openings, such as for loading and unloading of articles. The tensioning state of the flexible door is critical to the sealing effect and the opening and closing smoothness of the opening. In these systems, the flexible door is normally opened and closed by a traction mechanism, the tension of which depends on the initial installation precision of the components of the traction mechanism and on the characteristics of the flexible door itself. However, during long-term use, the flexible door may undergo a certain degree of tensile deformation, or the connection members of the traction mechanism may undergo a minute displacement due to vibration, abrasion, or the like, which may cause a decrease in the tension of the flexible door. Once the tension is insufficient, the flexible door may be loose and sealed, and even jamming or unstable operation may occur in the opening and closing process, which affects the normal use of the box assembly.
