Comb foundation machine for roller alignment by using helical gear pair

The utility model relates to a device for producing artificial honeycomb foundations. In order to overcome the defects that the process of aligning and adjusting two rollers of a conventional comb foundation machine is complicated and the precision is not easy to control, heads of the two rollers are respectively equipped with one helical gear with identical number of teeth and identical shape by the mode of key joints. Based on the principle that the change of axial opposite positions of two helical gears during the engagement of the helical gear pair surely leads to the change of circumferential opposite positions of the two helical gears, the driving helical gear is fixed on one end of the upper roller, and the driven helical gear is installed to the other end of the lower roller. The axial position of the driven helical gear can be changed by arranging pads with different thicknesses, so as to achieve the aim of roller alignment.
