The apparatus comprises: an assembly defining a drive axis, a translation axis perpendicular to the drive axis and an offset axis perpendicular to both the drive and translation axes, the assembly including a yoke; a shuttle mounted to the yoke for reciprocating motion along the yoke parallel to the translation axis; and a pair of drive mechanisms spaced apart from one another in the direction of the offset axis and disposed in flanking relation to the yoke, each drive mechanism including a body that follows a closed loop, said body being operatively coupled to the shuttle to reciprocate the yoke along a path parallel to the drive axis.

A mixing device with rotatable container, which can simultaneously meet the sealing, material mixing and cleaning requirements of large-sized mixers, includes a fixed container having a top opening; a mixing container having a top opening and a bottom material outlet, rotatably connected to and positioned inside the fixed container; a driving cover configured to open or close the top opening of the fixed container; a mixing container cover integrally and coaxially arranged with the driving cover and to rotate relative to the driving cover, configured to open or close the top opening of the mixing container and to rotate synchronously with the mixing container after the mixing container is covered by the mixing container cover; and a discharge and sealing mechanism arranged coaxially with the driving cover to form an integral body, and configured to open or close the material outlet from inside.

Disclosed is a mixed reactor and a method for preparing electrothermal film precursor solution based on the mixed reactor. The mixed reactor includes a reaction kettle body, a reflux condensation mechanism, and a multifunctional stirring mechanism. The reflux condensation mechanism includes a condensate tank, a condensing coil is wound around inside of the condensate tank, two ends of the condensing coil are horizontally arranged, and hermetically and rotatably installed on both sides of the condensate tank, the condensing coil is driven by a coil driving motor; the multifunctional stirring mechanism includes a stirring shaft and a plurality of stirring blades driven by the stirring shaft. The bottom of the stirring shaft is fixedly sleeved with an isolation sleeve. Buffer rubber gaskets are hermetically connected between the mounting parts and the installation holes. It can effectively improve the quality of products and the quality controllability during the product preparation process.
