Abstract

The invention relates to a rotary automatic expansion-releasing paper collet, which comprises a flange spindle, wherein an axial groove is reserved on the outer surface of the flange spindle; a shell is sleeved outside the flange spindle; an axial slide guide hole is reserved on the shell; a slide plate is arranged in the axial slide guide hole of the shell; a cylindrical pin is arranged between the slide plate and the flange spindle; an end cover is connected with the axial end of the flange spindle; and an axial through hole is reserved on the flange spindle. The rotary automatic expansion-releasing paper collet of the invention has multiple purposes, can be independently used, and can also be converted into a multi-section combined paper collet which is used for binding and clamping base paper spindles with various specifications. The conversion is simple; the number of mechanical spare parts is reduced; and the cost is saved.

Description

technical field [0001] The invention relates to a rotating and clamping part for a paper mandrel on a paper machine, in particular to a rotating automatic swelling paper chuck, which belongs to the technical field of mechanical rotating and clamping devices. Background technique [0002] The shafts used for roll paper in paper mills are basically hollow shafts made of hard paper because of their low cost and light weight. When used in production, the base paper chucks extend into the inner holes at both ends of the hollow shaft, and the base paper chucks expand the inner holes of the hollow shaft and drive it to rotate to roll or unload paper. [0003] The existing base paper chuck includes a flange mandrel, a shell, a sliding plate, a cylindrical pin and an end cover. An axial groove is opened on the outer surface of the flange mandrel, and a shell is set outside the flange mandrel. There is an axial guide hole on the top, and a sliding plate is installed in the guiding ho...
