The invention discloses a main transmission device for a strip wrapping
machine. The main transmission device comprises a crossbeam and a plurality of transmission elements. The transmission elementsare detachably and fixedly mounted on the crossbeam at intervals, the transmission elements include bases, spindles and connecting rod mechanisms, the spindles are vertically and rotatably mounted onthe bases, the lower sides of the right ends of the bases are rotatably mounted on the lower end of the crossbeam, the right ends of the connecting rod mechanisms are rotatably connected to the upperend of the crossbeam, the left ends of the connecting rod mechanisms are rotatably connected to the left ends of the bases, the spindles the transmission elements are connected with a
transmission belt in a transmission mode, the connecting rod mechanisms are used for controlling the joint transmission or detachment of the spindles of the transmission elements with the
transmission belt, and wirethrough hole penetrating through axes are formed in the spindles. The structure design of the main transmission device is simple and reasonable, the synchronous operation of the multiple transmissionunits is driven by the
transmission belt, the working efficiency of the strip wrapping
machine equipment with the main transmission device is ensured, and each transmission unit can be controlled separately; and the structure design of the strip wrapping
machine can be simplified, and the production,
processing and maintenance efficiency of the strip wrapping machine can be guaranteed.
