Sheet arranging and conveying mechanism

Abstract

The invention belongs to the technical field of disposable hygienic product equipment, and particularly relates to a sheet arranging and conveying mechanism which comprises a sucker assembly and an arranging assembly. The sucker assembly comprises an inner sucker and an outer sucker which are the same in structure, the inner sucker and the outer sucker each comprise an air suction box, and a firstguide wheel and a second guide wheel are arranged at the bottom end of each air suction box. Air distribution assemblies provides suction force for the air suction boxes to adsorb rear lugs. The arranging assembly comprises a spiral rotor and a fixed cam which are coaxially arranged. The fixed cam is fixedly supported by a supporting assembly, and the spiral rotor is driven by a transmission assembly to rotate. An even number of spiral guide rails are sequentially arranged along the circumferential surface of the spiral rotor, a certain included angle is formed between the spiral guide railsand the axis of the spiral rotor, and two circumferentially closed track grooves are formed in the circumferential surface of the fixed cam. The first guide wheels of the inner sucker slide along onetrack groove, the first guide wheels of the outer sucker slide along the other track groove, the second guide wheels are matched with the corresponding spiral guide rails, and the inner sucker and theouter sucker in one set slide reversely along the adjacent spiral guide rails.

Description

technical field [0001] The invention belongs to the technical field of disposable sanitary products, and in particular relates to a sheet material arrangement and conveyance mechanism. Background technique [0002] H-shaped diapers (with front and rear ears) are relatively new products in disposable sanitary products compared with traditional arc-cut diapers. The advantage is that it can save raw materials, and the unique elastic back ear can make consumers more comfortable to wear. However, the production difficulty of this kind of product is much higher than that of ordinary arc-cut diaper products, and the bottleneck of limitation lies in the accurate compounding of the elastic back ear and the product. It is reflected in the fact that the elastic back ear is a stretchable and soft material, and a single back ear is easy to wrinkle during cross-mechanism transmission; there is a huge speed difference between the cut back ear and the product, and it cannot be directly com...

Problems solved by technology

[0003] In order to solve the problem existing in the prior art that at least two sets of transfer mechanisms are required to realize a pair of rear ears transported in a single way from horizontal arrangement to longitudinal arrangement, and the risk of the rear ears getting out of control in cross-mechanism transfer increases, the present invention provides a sheet material Arrangement conveyor mechanism
