Straight strip folding device for sanitary towels and panty liners and folding method of straight strip folding device

Abstract

The invention discloses a straight strip folding device for sanitary towels and panty liners and a folding method of the straight strip folding device. The straight strip folding device comprises an installation plate, a main supporting shaft, an air distributing chamber, an inside rotary disc, an outside rotary disc, a driving motor and a transmission structure, wherein the inside rotary disc andthe outside rotary disc synchronously rotate, a plurality of air boxes are installed on the inside rotary disc, each air box is provided with a pair of rocker arms, and a rocker arm end face cam, a central cam and a lifting cam are installed between the inside rotary disc and the outside rotary disc from the transmission side to the operation side in sequence. One ends of the rocker arms are connected with the rocker arm end face cam, the other ends of the rocker arms are provided with push rods, a plurality of press plate assemblies are installed on the outside rotary disc, and each press plate assembly comprises a press plate, a slider and a guide rail installation plate. The sliders are slidably connected to the guide rail installation plates, the press plates are installed at the front ends of the tops of the sliders, the bottoms of the sliders are connected with the central cam, and one sides of the guide installation plates are slidably connected to the outside rotary disc. Thestraight strip folding device is simple in structure, low in space occupation, high in production efficiency and high in folding stability, and the processing steps are reduced.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and in particular relates to a device for folding straight strips of sanitary napkins and protective pads and a folding method thereof. Background technique [0002] In the production process of sanitary napkins and panty liners, there is usually a straight folding process. The traditional straight folding device generally needs to rotate the product substrate delivered by the front end by 90°, and then laminate the bottom film. Folding again leads to the need to use several transfer wheels to transfer and laminate the material, so that the lamination and folding need to be reduced to achieve good lamination and folding. Not only the structure of the device is complicated, the floor space is large, but also there are many processing procedures, which affects production. At the same time, the folding stability of the product and the shape effect of the folded product cannot be guaranteed. ...
