Abstract

The shaft withdrawing device for paper roll perforator includes one frame, one driving mechanism and one shifting mechanism. The driving mechanism includes one speed reducer, one tightening wheel and one driving chain connected between the speed reducer and the driving wheel, and there are also one spindle locating support with notch inside the driving wheel and paper roll supporting shafts on two sides of the driving chain. The shifting mechanism includes one shifting bottom board and one shifting baffle connected to the shifting bottom board, the shifting bottom board is connected to the driving chain and can shift between the spindle locating support and the driving wheel, and the shifting baffle has notch with direction and height corresponding to that in the spindle locating support. The present invention locates the spindle with the spindle locating support and its shifting baffle pushes the paper rolls to withdraw from the spindle automatically.

Description

technical field [0001] The invention relates to an auxiliary equipment for a rewinding and punching machine for household paper, in particular to a shaft-drawing device for a rewinding and punching machine for household paper. Background technique [0002] The rewinding production of household paper is to wind the paper core on the mandrel through the rewinding punching machine to make it rewind and form it. After the paper core is rewinded and formed, the paper is sealed. After the paper sealing is completed, the mandrel needs to be pulled out from the paper roll, and then the paper roll is cut and packaged. At present, the extraction of the mandrel is done manually by hand. One person needs to hold down the paper roll while the other extracts the mandrel. The operation is cumbersome, labor-intensive and time-consuming, which increases the labor intensity of the staff. Contents of the invention [0003] The object of the present invention is to provide a shaft-drawing de...
