Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.

As shown in fig. 1 and 2, a quick replacing structure for unwinding rollers of a rewinding machine comprises two side plates 1, a horizontal conveying device and a vertical lifting device; horizontal grooves 2 for allowing unwinding rollers 18 to penetrate are formed in the inner sides of the lower ends of the side plates 1, vertical grooves 3 are formed in the inner sides of the side plates 1 in the vertical direction, roller grooves 4 for allowing roller shafts 19 of the unwinding rollers 18 to be placed are formed in the inner sides of the top ends of the side plates 1, and one side wall of each vertical groove 3 is communicated with the roller groove 4; the horizontal conveying device comprises a conveying belt 5, carrier rollers, a driving wheel 6, a driven wheel 7 and a first motor, wherein the driving wheel 6 and the driven wheel 7 are respectively arranged at two ends of the lower side of the horizontal groove 2, the carrier rollers are arranged between the driving wheel 6 and the driven wheel 7 at equal intervals, the conveying belt 5 is arranged around the driving wheel 6, the driven wheel 7 and the carrier rollers, and the driving wheel 6 is driven by the first motor; vertical lifting device includes lead screw 8, the tray, second motor 15, the tray face of tray upper end is horizontal tray face 10 and slope tray face 11 from one side to the opposite side, the tray is equipped with screw 12, lead screw 8 passes screw 12 and is connected with the tray meshing, the bottom fixed connection of lead screw 8 has the first bevel gear 13 of level setting, the bottom rotatable coupling of first bevel gear 13 has support piece 16, the drive end of second motor 15 passes 1 fixedly connected with perpendicular second bevel gear 14 that sets up of curb plate, first bevel gear 13 is connected with second bevel gear 14 meshing, lead screw 8 and tray are all located in vertical groove 3.

The depths of the horizontal groove 2, the vertical groove 3 and the roller groove 4 are the same.
