Roll paper extracting device

Abstract

The invention relates to a roll paper extracting device which comprises a wheel drum and a pressing shaft corresponding to the wheel drum. Roll paper penetrates between the wheel drum and the pressing shaft. The two ends of the wheel drum are mounted on the main shaft portion of an eccentric shaft, and a paper cutter is mounted on the eccentric portion of the eccentric shaft. A guide groove is formed in the wheel drum, and the paper cutter is limited in the guide groove. The roller paper is pulled with external force to drive the wheel drum to rotate, the wheel drum drives the paper cutter to rotate synchronously, the paper cutter stretches out of the long and thin groove of the wheel drum to cut the roll paper under the action of the eccentric shaft, and the cut-off position of the paper is determined. After the paper cutter stretches out of the long and thin groove of the wheel drum to cut off the roll paper, the wheel drum is driven by a reset spring to continue to rotate forwards to be reset, and a paper head is driven to stretch out of the machine by a distance to execute the next extracting action conveniently. A mechanical mechanism is provided, the performance and function similar to those of a paper extracting machine can be achieved, mounting is simplified, paper cutting is reliable and stable, part cost is reduced, and great economic benefits can be brought.

Description

technical field [0001] The invention relates to a paper pumping device, in particular to a roll paper pumping device, and belongs to the technical field of roll paper tissue pumping devices. Background technique [0002] Paper towels are very common in public places and households, and there are three main types of paper dispensers for this type of paper towels. One is to place the cut paper towels of a fixed length in the paper pumping machine, and when the user pulls out a paper towel, the next paper towel is ready; the second is to place each fixed length of the whole roll of paper towels There is a row of dotted holes for the user to break off; the third type is the small holes that are not dotted in the whole roll of paper, and a certain fixed length of paper towels is cut through various movement modes of the paper pumping machine. [0003] Among these three types of paper pumping machines, the third type has the lowest requirement for paper, so it is more economical....
