Detailed description of the invention
Below in conjunction with accompanying drawing, describe the specific embodiments of the drive unit of last volume sideband in a kind of crimping machine described in the utility model in detail for V-belt for Rolldown hem band:
As Fig. 1, shown in Fig. 2 and Fig. 3, the drive unit of last volume sideband in a kind of crimping machine described in the utility model, comprise: frame 1, frame 1 is movably set with the driving shaft 2 be parallel to each other, Rolldown hem bridge shaft 3, first Rolldown hem axle 4 and the second Rolldown hem axle 5, wherein, first Rolldown hem axle 4 is near Rolldown hem bridge shaft 3, described Rolldown hem bridge shaft 3 comprises: Rolldown hem gap bridge driving shaft 31, Rolldown hem gap bridge driven axle 33 and being arranged between Rolldown hem gap bridge driving shaft 31 and Rolldown hem gap bridge driven axle 33 for controlling the overbridge clutch 32 of Rolldown hem gap bridge driving shaft 31 and the clutch of Rolldown hem gap bridge driven axle 33, overbridge clutch 32 is provided with clutch handle 321, the respective two ends of described driving shaft 2, Rolldown hem gap bridge driving shaft 31, Rolldown hem gap bridge driven axle 33, first Rolldown hem axle 4 and the second Rolldown hem axle 5 are all arranged in frame 1 by bearing and bearing block, described driving shaft 2 are provided with the drive sprocket 21 linked with the driving chain on glove line and the Rolldown hem gap bridge drive sprocket 22 driving Rolldown hem bridge shaft 3, described Rolldown hem gap bridge driving shaft 31 is provided with the Rolldown hem gap bridge drive sprocket 311 matched with Rolldown hem gap bridge drive sprocket 22, Rolldown hem gap bridge drive sprocket 311 and Rolldown hem gap bridge drive sprocket 22 are engaged with Rolldown hem gap bridge driving chain 203, Rolldown hem gap bridge driven axle 33 is provided with Rolldown hem drive sprocket 331, the first described Rolldown hem axle 4 is provided with the Rolldown hem drive sprocket 41 matched with Rolldown hem drive sprocket 331 and is positioned at the first last volume cincture 42 of Rolldown hem drive sprocket 41 both sides for a pair, Rolldown hem drive sprocket 41 and described Rolldown hem drive sprocket 331 are engaged with Rolldown hem driving chain 304, the second described Rolldown hem axle 5 is provided with a pair and the first last volume cincture 42 second last volume cincture 52 one to one, first last volume cincture 42 and the second last volume cincture 52 are vee-pulley.
