[0002] The bag-opening clamping and closing assembly is a device component used to handle bags, especially large bags such as ton bags. A solid fluid refers to a solid substance subjected to low stress at temperatures below its melting point. Its total strain consists of four components: elastic strain, plastic strain, transient creep, and viscous strain. As the stress duration increases, the other strain components become less significant, leaving only the viscous strain in a steady-state state. When the stress persists long enough for the viscous strain to exceed the elastic strain by at least three orders of magnitude, the object essentially behaves like a viscous fluid. With the development of society, the bag-opening clamping and closing assembly is used when ton bags need to be closed.
