Two-for-one twister transmission device with universal joint coupler

The utility model provides a two-for-one twister transmission device with a universal joint coupler. Relating to the technical field of twisting mechanisms, the device comprises a rack, a driving motor, a first-layer belt wheel, a universal joint coupler, a transmission shaft, a supporting base and a second-layer belt wheel, the rack comprises an upper-layer support table and a lower-layer supporttable. The driving motor is fixedly mounted on the upper-layer bracket table; the first-layer belt wheel and the connecting end of the universal joint coupler are coaxially installed, the other connecting end of the universal joint coupler and the transmission shaft are coaxially installed in a matched mode, the supporting base is fixed to the lower-layer support table, the transmission shaft penetrates through the base support to be connected with the second-layer belt wheel, and the driving motor drives the first-layer belt wheel and the universal joint coupler to rotate. The two-for-one twister solves the technica
