The invention relates to disposable hygiene product production equipment, in particular to a rotating pitch change mechanism for hygiene products. The rotating pitch change mechanism comprises a rackand a main shaft fixed on the rack, wherein the main shaft is rotationally connected with a driving disk; a sucker base is circumferentially arranged on the driving disk in a sliding manner; a suckerassembly is arranged on the sucker base; a reversing mechanism and a pitch change mechanism are arranged between the sucker base and the main shaft; the reversing mechanism comprises a sucker shaft rotationally connected to the sucker base; a cam disk is fixed on the main shaft; a guide groove is formed in the circumferential wall of the cam disk; a rocker arm is installed at the root part of thesucker shaft extending out of the sucker base and is rotationally connected with a first guide wheel; and the first guide wheel moves in the cam disk along the guide groove. According to the rotatingpitch change mechanism, materials can be reversed when transported and subjected to pitch change, that is to say, the reversing mechanism is added. According to the rotating pitch change mechanism forthe hygiene products, original five groups of link mechanisms are replaced with existing three groups of link mechanisms, so that the internal structure of the whole component is simplified, and theposition accuracy and stability of a rotary adsorption disk at the tail end during operation are improved.
Description
technical field [0001] The invention relates to a production equipment for disposable sanitary products, in particular to a rotary distance-changing mechanism for sanitary products. Background technique [0002] The patent number is CN201410294675.1 (reversing and pitch-changing assembly for sanitary products), which discloses a solution for changing the angle and speed of objects on the circumference. Through the compound movement of multiple sets of connecting rods and cam mechanisms, each adsorption device can be changed. The angle and the angular velocity running on the circular guide rail, so as to realize the angle difference and speed difference at the receiving and discarding positions. It is possible to change the angle of each piece of material and the distance between them after passing through the device. The internal structure of this device is relatively complicated. Each unit needs to use multiple sets of connecting rods to change the distance. The joints at ...
